A BILL FOR

AN ACT concerning revenue.

Be it enacted by the People of the State of Illinois, represented in the General Assembly:

Section 5. The Illinois Income Tax Act is amended by changing Sections 203, 304, and 1501 and by adding Section 1009 as follows:

(35 ILCS 5/203) (from Ch. 120, par. 2-203)

Sec. 203. Base income defined.

(a) Individuals.

(1) In general. In the case of an individual, base income means an amount equal to the taxpayer's adjusted gross income for the taxable year as modified by paragraph (2).

(2) Modifications. The adjusted gross income referred to in paragraph (1) shall be modified by adding thereto the sum of the following amounts:

(A) An amount equal to all amounts paid or accrued to the taxpayer as interest or dividends during the taxable year to the extent excluded from gross income in the computation of adjusted gross income, except stock dividends of qualified public utilities described in Section 305(e) of the Internal Revenue Code;

(B) An amount equal to the amount of tax imposed by this Act to the extent deducted from gross income in the computation of adjusted gross income for the taxable year;

(C) An amount equal to the amount received during the taxable year as a recovery or refund of real property taxes paid with respect to the taxpayer's principal residence under the Revenue Act of 1939 and for which a deduction was previously taken under subparagraph (L) of this paragraph (2) prior to July 1, 1991, the retrospective application date of Article 4 of Public Act 87-17. In the case of multi-unit or multi-use structures and farm dwellings, the taxes on the taxpayer's principal residence shall be that portion of the total taxes for the entire property which is attributable to such principal residence;

(D) An amount equal to the amount of the capital gain deduction allowable under the Internal Revenue Code, to the extent deducted from gross income in the computation of adjusted gross income;

(D-5) An amount, to the extent not included in adjusted gross income, equal to the amount of money withdrawn by the taxpayer in the taxable year from a medical care savings account and the interest earned on the account in the taxable year of a withdrawal pursuant to subsection (b) of Section 20 of the Medical Care Savings Account Act or subsection (b) of Section 20 of the Medical Care Savings Account Act of 2000;

(D-10) For taxable years ending after December 31, 1997, an amount equal to any eligible remediation costs that the individual deducted in computing adjusted gross income and for which the individual claims a credit under subsection (l) of Section 201;

(D-15) For taxable years 2001 through 2025, an amount equal to the bonus depreciation deduction taken on the taxpayer's federal income tax return for the taxable year under subsection (k) of Section 168 of the Internal Revenue Code; for taxable years 2026 and thereafter, an amount equal to the bonus depreciation deduction taken on the taxpayer's federal income tax return for the taxable year under subsection (k) or (n) of Section 168 of the Internal Revenue Code;

(D-16) If the taxpayer sells, transfers, abandons, or otherwise disposes of property for which the taxpayer was required in any taxable year to make an addition modification under subparagraph (D-15), then an amount equal to the aggregate amount of the deductions taken in all taxable years under subparagraph (Z) with respect to that property.

If the taxpayer continues to own property through the last day of the last tax year for which a subtraction is allowed with respect to that property under subparagraph (Z) and for which the taxpayer was allowed in any taxable year to make a subtraction modification under subparagraph (Z), then an amount equal to that subtraction modification.

The taxpayer is required to make the addition modification under this subparagraph only once with respect to any one piece of property;

(D-17) An amount equal to the amount otherwise allowed as a deduction in computing base income for interest paid, accrued, or incurred, directly or indirectly, (i) for taxable years ending on or after December 31, 2004 and ending before January 1, 2027, to a foreign person who would be a member of the same unitary business group but for the fact that foreign person's business activity outside the United States is 80% or more of the foreign person's total business activity and (ii) for taxable years ending on or after December 31, 2008, to a person who would be a member of the same unitary business group but for the fact that the person is prohibited under Section 1501(a)(27) from being included in the unitary business group because he or she is ordinarily required to apportion business income under different subsections of Section 304. The addition modification required by this subparagraph shall be reduced to the extent that dividends were included in base income of the unitary group for the same taxable year and received by the taxpayer or by a member of the taxpayer's unitary business group (including amounts included in gross income under Sections 951 through 964 of the Internal Revenue Code and amounts included in gross income under Section 78 of the Internal Revenue Code) with respect to the stock of the same person to whom the interest was paid, accrued, or incurred. For taxable years ending on and after December 31, 2025, for purposes of applying this paragraph in the case of a taxpayer to which Section 163(j) of the Internal Revenue Code applies for the taxable year, the reduction in the amount of interest for which a deduction is allowed by reason of Section 163(j) shall be treated as allocable first to persons who are not foreign persons referred to in this paragraph and then to such foreign persons.

For taxable years ending before December 31, 2025, this paragraph shall not apply to the following:

(i) an item of interest paid, accrued, or incurred, directly or indirectly, to a person who is subject in a foreign country or state, other than a state which requires mandatory unitary reporting, to a tax on or measured by net income with respect to such interest; or

(ii) an item of interest paid, accrued, or incurred, directly or indirectly, to a person if the taxpayer can establish, based on a preponderance of the evidence, both of the following:

(a) the person, during the same taxable year, paid, accrued, or incurred, the interest to a person that is not a related member, and

(b) the transaction giving rise to the interest expense between the taxpayer and the person did not have as a principal purpose the avoidance of Illinois income tax, and is paid pursuant to a contract or agreement that reflects an arm's-length interest rate and terms; or

(iii) the taxpayer can establish, based on clear and convincing evidence, that the interest paid, accrued, or incurred relates to a contract or agreement entered into at arm's-length rates and terms and the principal purpose for the payment is not federal or Illinois tax avoidance; or

(iv) an item of interest paid, accrued, or incurred, directly or indirectly, to a person if the taxpayer establishes by clear and convincing evidence that the adjustments are unreasonable; or if the taxpayer and the Director agree in writing to the application or use of an alternative method of apportionment under Section 304(f).

For taxable years ending on or after December 31, 2025, this paragraph shall not apply to the following:

(i) an item of interest paid, accrued, or incurred, directly or indirectly, to a person if the taxpayer can establish, based on a preponderance of the evidence, both of the following:

(a) the person, during the same taxable year, paid, accrued, or incurred, the interest to a person that is not a related member, and

(b) the transaction giving rise to the interest expense between the taxpayer and the person did not have as a principal purpose the avoidance of Illinois income tax and is paid pursuant to a contract or agreement that reflects an arm's-length interest rate and terms; or

(ii) an item of interest paid, accrued, or incurred, directly or indirectly, to a person if the taxpayer establishes by clear and convincing evidence that the adjustments are unreasonable; or if the taxpayer and the Director agree in writing to the application or use of an alternative method of apportionment under Section 304(f).

Nothing in this subsection shall preclude the Director from making any other adjustment otherwise allowed under Section 404 of this Act for any tax year beginning after the effective date of this amendment provided such adjustment is made pursuant to regulation adopted by the Department and such regulations provide methods and standards by which the Department will utilize its authority under Section 404 of this Act;

(D-18) An amount equal to the amount of intangible expenses and costs otherwise allowed as a deduction in computing base income, and that were paid, accrued, or incurred, directly or indirectly, (i) for taxable years ending on or after December 31, 2004 and ending before January 1, 2027, to a foreign person who would be a member of the same unitary business group but for the fact that the foreign person's business activity outside the United States is 80% or more of that person's total business activity and (ii) for taxable years ending on or after December 31, 2008, to a person who would be a member of the same unitary business group but for the fact that the person is prohibited under Section 1501(a)(27) from being included in the unitary business group because he or she is ordinarily required to apportion business income under different subsections of Section 304. The addition modification required by this subparagraph shall be reduced to the extent that dividends were included in base income of the unitary group for the same taxable year and received by the taxpayer or by a member of the taxpayer's unitary business group (including amounts included in gross income under Sections 951 through 964 of the Internal Revenue Code and amounts included in gross income under Section 78 of the Internal Revenue Code) with respect to the stock of the same person to whom the intangible expenses and costs were directly or indirectly paid, incurred, or accrued. The preceding sentence does not apply to the extent that the same dividends caused a reduction to the addition modification required under Section 203(a)(2)(D-17) of this Act. As used in this subparagraph, the term "intangible expenses and costs" includes (1) expenses, losses, and costs for, or related to, the direct or indirect acquisition, use, maintenance or management, ownership, sale, exchange, or any other disposition of intangible property; (2) losses incurred, directly or indirectly, from factoring transactions or discounting transactions; (3) royalty, patent, technical, and copyright fees; (4) licensing fees; and (5) other similar expenses and costs. For purposes of this subparagraph, "intangible property" includes patents, patent applications, trade names, trademarks, service marks, copyrights, mask works, trade secrets, and similar types of intangible assets.

For taxable years ending before December 31, 2025, this paragraph shall not apply to the following:

(i) any item of intangible expenses or costs paid, accrued, or incurred, directly or indirectly, from a transaction with a person who is subject in a foreign country or state, other than a state which requires mandatory unitary reporting, to a tax on or measured by net income with respect to such item; or

(ii) any item of intangible expense or cost paid, accrued, or incurred, directly or indirectly, if the taxpayer can establish, based on a preponderance of the evidence, both of the following:

(a) the person during the same taxable year paid, accrued, or incurred, the intangible expense or cost to a person that is not a related member, and

(b) the transaction giving rise to the intangible expense or cost between the taxpayer and the person did not have as a principal purpose the avoidance of Illinois income tax, and is paid pursuant to a contract or agreement that reflects arm's-length terms; or

(iii) any item of intangible expense or cost paid, accrued, or incurred, directly or indirectly, from a transaction with a person if the taxpayer establishes by clear and convincing evidence, that the adjustments are unreasonable; or if the taxpayer and the Director agree in writing to the application or use of an alternative method of apportionment under Section 304(f);

For taxable years ending on or after December 31, 2025, this paragraph shall not apply to the following:

(i) any item of intangible expense or cost paid, accrued, or incurred, directly or indirectly, if the taxpayer can establish, based on a preponderance of the evidence, both of the following:

(a) the person during the same taxable year paid, accrued, or incurred, the intangible expense or cost to a person that is not a related member, and

(b) the transaction giving rise to the intangible expense or cost between the taxpayer and the person did not have as a principal purpose the avoidance of Illinois income tax, and is paid pursuant to a contract or agreement that reflects arm's-length terms; or

(ii) any item of intangible expense or cost paid, accrued, or incurred, directly or indirectly, from a transaction with a person if the taxpayer establishes by clear and convincing evidence, that the adjustments are unreasonable; or if the taxpayer and the Director agree in writing to the application or use of an alternative method of apportionment under Section 304(f).

Nothing in this subsection shall preclude the Director from making any other adjustment otherwise allowed under Section 404 of this Act for any tax year beginning after the effective date of this amendment provided such adjustment is made pursuant to regulation adopted by the Department and such regulations provide methods and standards by which the Department will utilize its authority under Section 404 of this Act;

(D-19) For taxable years ending on or after December 31, 2008, an amount equal to the amount of insurance premium expenses and costs otherwise allowed as a deduction in computing base income, and that were paid, accrued, or incurred, directly or indirectly, to a person who would be a member of the same unitary business group but for the fact that the person is prohibited under Section 1501(a)(27) from being included in the unitary business group because he or she is ordinarily required to apportion business income under different subsections of Section 304. The addition modification required by this subparagraph shall be reduced to the extent that dividends were included in base income of the unitary group for the same taxable year and received by the taxpayer or by a member of the taxpayer's unitary business group (including amounts included in gross income under Sections 951 through 964 of the Internal Revenue Code and amounts included in gross income under Section 78 of the Internal Revenue Code) with respect to the stock of the same person to whom the premiums and costs were directly or indirectly paid, incurred, or accrued. The preceding sentence does not apply to the extent that the same dividends caused a reduction to the addition modification required under Section 203(a)(2)(D-17) or Section 203(a)(2)(D-18) of this Act;

(D-20) For taxable years beginning on or after January 1, 2002 and ending on or before December 31, 2006, in the case of a distribution from a qualified tuition program under Section 529 of the Internal Revenue Code, other than (i) a distribution from a College Savings Pool created under Section 16.5 of the State Treasurer Act or (ii) a distribution from the Illinois Prepaid Tuition Trust Fund, an amount equal to the amount excluded from gross income under Section 529(c)(3)(B).

In the case of a corporation which is a member of an affiliated group of corporations filing a consolidated income tax return for the taxable year for federal income tax purposes, taxable income determined as if such corporation had filed a separate return for federal income tax purposes for the taxable year and each preceding taxable year for which it was a member of an affiliated group. For purposes of this subparagraph, the taxpayer's separate taxable income shall be determined as if the election provided by Section 243(b)(2) of the Internal Revenue Code had been in effect for all such years;

(F) Cooperatives. In the case of a cooperative corporation or association, the taxable income of such organization determined in accordance with the provisions of Section 1381 through 1388 of the Internal Revenue Code, but without regard to the prohibition against offsetting losses from patronage activities against income from nonpatronage activities; except that a cooperative corporation or association may make an election to follow its federal income tax treatment of patronage losses and nonpatronage losses. In the event such election is made, such losses shall be computed and carried over in a manner consistent with subsection (a) of Section 207 of this Act and apportioned by the apportionment factor reported by the cooperative on its Illinois income tax return filed for the taxable year in which the losses are incurred. The election shall be effective for all taxable years with original returns due on or after the date of the election. In addition, the cooperative may file an amended return or returns, as allowed under this Act, to provide that the election shall be effective for losses incurred or carried forward for taxable years occurring prior to the date of the election. Once made, the election may only be revoked upon approval of the Director. The Department shall adopt rules setting forth requirements for documenting the elections and any resulting Illinois net loss and the standards to be used by the Director in evaluating requests to revoke elections. Public Act 96-932 is declaratory of existing law;

(G) Subchapter S corporations. In the case of: (i) a Subchapter S corporation for which there is in effect an election for the taxable year under Section 1362 of the Internal Revenue Code, the taxable income of such corporation determined in accordance with Section 1363(b) of the Internal Revenue Code, except that taxable income shall take into account those items which are required by Section 1363(b)(1) of the Internal Revenue Code to be separately stated; and (ii) a Subchapter S corporation for which there is in effect a federal election to opt out of the provisions of the Subchapter S Revision Act of 1982 and have applied instead the prior federal Subchapter S rules as in effect on July 1, 1982, the taxable income of such corporation determined in accordance with the federal Subchapter S rules as in effect on July 1, 1982; and

(H) Partnerships. In the case of a partnership, taxable income determined in accordance with Section 703 of the Internal Revenue Code, except that taxable income shall take into account those items which are required by Section 703(a)(1) to be separately stated but which would be taken into account by an individual in calculating his taxable income.

(3) Recapture of business expenses on disposition of asset or business. Notwithstanding any other law to the contrary, if in prior years income from an asset or business has been classified as business income and in a later year is demonstrated to be non-business income, then all expenses, without limitation, deducted in such later year and in the 2 immediately preceding taxable years related to that asset or business that generated the non-business income shall be added back and recaptured as business income in the year of the disposition of the asset or business. Such amount shall be apportioned to Illinois using the greater of the apportionment fraction computed for the business under Section 304 of this Act for the taxable year or the average of the apportionment fractions computed for the business under Section 304 of this Act for the taxable year and for the 2 immediately preceding taxable years.

(f) Valuation limitation amount.

(1) In general. The valuation limitation amount referred to in subsections (a)(2)(G), (c)(2)(I) and (d)(2)(E) is an amount equal to:

(A) The sum of the pre-August 1, 1969 appreciation amounts (to the extent consisting of gain reportable under the provisions of Section 1245 or 1250 of the Internal Revenue Code) for all property in respect of which such gain was reported for the taxable year; plus

(B) The lesser of (i) the sum of the pre-August 1, 1969 appreciation amounts (to the extent consisting of capital gain) for all property in respect of which such gain was reported for federal income tax purposes for the taxable year, or (ii) the net capital gain for the taxable year, reduced in either case by any amount of such gain included in the amount determined under subsection (a)(2)(F) or (c)(2)(H).

(2) Pre-August 1, 1969 appreciation amount.

(A) If the fair market value of property referred to in paragraph (1) was readily ascertainable on August 1, 1969, the pre-August 1, 1969 appreciation amount for such property is the lesser of (i) the excess of such fair market value over the taxpayer's basis (for determining gain) for such property on that date (determined under the Internal Revenue Code as in effect on that date), or (ii) the total gain realized and reportable for federal income tax purposes in respect of the sale, exchange or other disposition of such property.

(B) If the fair market value of property referred to in paragraph (1) was not readily ascertainable on August 1, 1969, the pre-August 1, 1969 appreciation amount for such property is that amount which bears the same ratio to the total gain reported in respect of the property for federal income tax purposes for the taxable year, as the number of full calendar months in that part of the taxpayer's holding period for the property ending July 31, 1969 bears to the number of full calendar months in the taxpayer's entire holding period for the property.

(C) The Department shall prescribe such regulations as may be necessary to carry out the purposes of this paragraph.

(g) Double deductions. Unless specifically provided otherwise, nothing in this Section shall permit the same item to be deducted more than once.

Sec. 304. Business income of persons other than residents.

(a) In general. The business income of a person other than a resident shall be allocated to this State if such person's business income is derived solely from this State. If a person other than a resident derives business income from this State and one or more other states, then, for tax years ending on or before December 30, 1998, and except as otherwise provided by this Section, such person's business income shall be apportioned to this State by multiplying the income by a fraction, the numerator of which is the sum of the property factor (if any), the payroll factor (if any) and 200% of the sales factor (if any), and the denominator of which is 4 reduced by the number of factors other than the sales factor which have a denominator of zero and by an additional 2 if the sales factor has a denominator of zero. For tax years ending on or after December 31, 1998, and except as otherwise provided by this Section, persons other than residents who derive business income from this State and one or more other states shall compute their apportionment factor by weighting their property, payroll, and sales factors as provided in subsection (h) of this Section.

(1) Property factor.

(A) The property factor is a fraction, the numerator of which is the average value of the person's real and tangible personal property owned or rented and used in the trade or business in this State during the taxable year and the denominator of which is the average value of all the person's real and tangible personal property owned or rented and used in the trade or business during the taxable year.

(B) Property owned by the person is valued at its original cost. Property rented by the person is valued at 8 times the net annual rental rate. Net annual rental rate is the annual rental rate paid by the person less any annual rental rate received by the person from sub-rentals.

(C) The average value of property shall be determined by averaging the values at the beginning and ending of the taxable year, but the Director may require the averaging of monthly values during the taxable year if reasonably required to reflect properly the average value of the person's property.

(2) Payroll factor.

(A) The payroll factor is a fraction, the numerator of which is the total amount paid in this State during the taxable year by the person for compensation, and the denominator of which is the total compensation paid everywhere during the taxable year.

(B) Compensation is paid in this State if:

(i) The individual's service is performed entirely within this State;

(ii) The individual's service is performed both within and without this State, but the service performed without this State is incidental to the individual's service performed within this State; or

(iii) For tax years ending prior to December 31, 2020, some of the service is performed within this State and either the base of operations, or if there is no base of operations, the place from which the service is directed or controlled is within this State, or the base of operations or the place from which the service is directed or controlled is not in any state in which some part of the service is performed, but the individual's residence is in this State. For tax years ending on or after December 31, 2020, compensation is paid in this State if some of the individual's service is performed within this State, the individual's service performed within this State is nonincidental to the individual's service performed without this State, and the individual's service is performed within this State for more than 30 working days during the tax year. The amount of compensation paid in this State shall include the portion of the individual's total compensation for services performed on behalf of his or her employer during the tax year which the number of working days spent within this State during the tax year bears to the total number of working days spent both within and without this State during the tax year. For purposes of this paragraph:

(a) The term "working day" means all days during the tax year in which the individual performs duties on behalf of his or her employer. All days in which the individual performs no duties on behalf of his or her employer (e.g., weekends, vacation days, sick days, and holidays) are not working days.

(b) A working day is spent within this State if:

(1) the individual performs service on behalf of the employer and a greater amount of time on that day is spent by the individual performing duties on behalf of the employer within this State, without regard to time spent traveling, than is spent performing duties on behalf of the employer without this State; or

(2) the only service the individual performs on behalf of the employer on that day is traveling to a destination within this State, and the individual arrives on that day.

(c) Working days spent within this State do not include any day in which the employee is performing services in this State during a disaster period solely in response to a request made to his or her employer by the government of this State, by any political subdivision of this State, or by a person conducting business in this State to perform disaster or emergency-related services in this State. For purposes of this item (c):

Conversely, duty days for any person who leaves a team during this period shall end on the day that person leaves the team. Where a person switches teams during a taxable year, a separate duty-day calculation shall be made for the period the person was with each team.

(D) Days for which a member of a professional athletic team is not compensated and is not performing services for the team in any manner, including days when such member of a professional athletic team has been suspended without pay and prohibited from performing any services for the team, shall not be treated as duty days.

This compensation shall include, but is not limited to, salaries, wages, bonuses as described in this subpart, and any other type of compensation paid during the taxable year to a member of a professional athletic team for services performed in that year. This compensation does not include strike benefits, severance pay, termination pay, contract or option year buy-out payments, expansion or relocation payments, or any other payments not related to services performed for the team.

(ii) In the case where film or radio programming is broadcast by a station, a network, or a cable system for a fee or other remuneration received from the recipient of the broadcast, the portion of the service that is received in this State is measured by the portion of the recipients of the broadcast located in this State. Accordingly, the fee or other remuneration for such service that is included in the Illinois numerator of the sales factor is the total of those fees or other remuneration received from recipients in Illinois. For purposes of this paragraph, a taxpayer may determine the location of the recipients of its broadcast using the address of the recipient shown in its contracts with the recipient or using the billing address of the recipient in the taxpayer's records.

(iii) In the case where film or radio programming is broadcast by a station, a network, or a cable system for a fee or other remuneration from the person providing the programming, the portion of the broadcast service that is received by such station, network, or cable system in this State is measured by the portion of recipients of the broadcast located in this State. Accordingly, the amount of revenue related to such an arrangement that is included in the Illinois numerator of the sales factor is the total fee or other total remuneration from the person providing the programming related to that broadcast multiplied by the Illinois audience factor for that broadcast.

(iv) In the case where film or radio programming is provided by a taxpayer that is a network or station to a customer for broadcast in exchange for a fee or other remuneration from that customer the broadcasting service is received at the location of the office of the customer from which the services were ordered in the regular course of the customer's trade or business. Accordingly, in such a case the revenue derived by the taxpayer that is included in the taxpayer's Illinois numerator of the sales factor is the revenue from such customers who receive the broadcasting service in Illinois.

(v) In the case where film or radio programming is provided by a taxpayer that is not a network or station to another person for broadcasting in exchange for a fee or other remuneration from that person, the broadcasting service is received at the location of the office of the customer from which the services were ordered in the regular course of the customer's trade or business. Accordingly, in such a case the revenue derived by the taxpayer that is included in the taxpayer's Illinois numerator of the sales factor is the revenue from such customers who receive the broadcasting service in Illinois.

(B-8) Gross receipts from winnings under the Illinois Lottery Law from the assignment of a prize under Section 13.1 of the Illinois Lottery Law are received in this State. This paragraph (B-8) applies only to taxable years ending on or after December 31, 2013.

(C) For taxable years ending before December 31, 2008, sales, other than sales governed by paragraphs (B), (B-1), (B-2), and (B-8) are in this State if:

(i) The income-producing activity is performed in this State; or

(ii) The income-producing activity is performed both within and without this State and a greater proportion of the income-producing activity is performed within this State than without this State, based on performance costs.

(C-5) For taxable years ending on or after December 31, 2008, sales, other than sales governed by paragraphs (B), (B-1), (B-2), (B-5), and (B-7), are in this State if any of the following criteria are met:

(i) Sales from the sale or lease of real property are in this State if the property is located in this State.

(ii) Sales from the lease or rental of tangible personal property are in this State if the property is located in this State during the rental period. Sales from the lease or rental of tangible personal property that is characteristically moving property, including, but not limited to, motor vehicles, rolling stock, aircraft, vessels, or mobile equipment are in this State to the extent that the property is used in this State.

(iii) In the case of interest, net gains (but not less than zero) and other items of income from intangible personal property, the sale is in this State if:

(a) in the case of a taxpayer who is a dealer in the item of intangible personal property within the meaning of Section 475 of the Internal Revenue Code, the income or gain is received from a customer in this State. For purposes of this subparagraph, a customer is in this State if the customer is an individual, trust or estate who is a resident of this State and, for all other customers, if the customer's commercial domicile is in this State. Unless the dealer has actual knowledge of the residence or commercial domicile of a customer during a taxable year, the customer shall be deemed to be a customer in this State if the billing address of the customer, as shown in the records of the dealer, is in this State;

(a-5) in the case of the sale or exchange of shares in a Subchapter S corporation or an interest in a partnership, other than an investment partnership as defined in paragraph (11.5) of subsection (a) of Section 1501, the Subchapter S corporation or partnership was taxable in this State; for purposes of this subparagraph, the amount attributable to this State shall be determined in proportion to the average of the pass-through entity's Illinois apportionment factor computed under this Section in the year of the sale or exchange and the 2 tax years immediately preceding the year of the sale or exchange; if the pass-through entity was not in existence during both of the preceding 2 years, then only the years in which the pass-through entity was in existence shall be considered when computing the average; or

(b) in all other cases, if the income-producing activity of the taxpayer is performed in this State or, if the income-producing activity of the taxpayer is performed both within and without this State, if a greater proportion of the income-producing activity of the taxpayer is performed within this State than in any other state, based on performance costs.

(iv) Sales of services are in this State if the services are received in this State. For the purposes of this section, gross receipts from the performance of services provided to a corporation, partnership, or trust may only be attributed to a state where that corporation, partnership, or trust has a fixed place of business. If the state where the services are received is not readily determinable or is a state where the corporation, partnership, or trust receiving the service does not have a fixed place of business, the services shall be deemed to be received at the location of the office of the customer from which the services were ordered in the regular course of the customer's trade or business. If the ordering office cannot be determined, the services shall be deemed to be received at the office of the customer to which the services are billed. If the taxpayer is not taxable in the state in which the services are received, the sale must be excluded from both the numerator and the denominator of the sales factor. The Department shall adopt rules prescribing where specific types of service are received, including, but not limited to, publishing, and utility service.

(D) For taxable years ending on or after December 31, 1995, the following items of income shall not be included in the numerator or denominator of the sales factor: dividends; amounts included under Section 78 of the Internal Revenue Code; and Subpart F income as defined in Section 952 of the Internal Revenue Code. No inference shall be drawn from the enactment of this paragraph (D) in construing this Section for taxable years ending before December 31, 1995.

(E) Paragraphs (B-1) and (B-2) shall apply to tax years ending on or after December 31, 1999, provided that a taxpayer may elect to apply the provisions of these paragraphs to prior tax years. Such election shall be made in the form and manner prescribed by the Department, shall be irrevocable, and shall apply to all tax years; provided that, if a taxpayer's Illinois income tax liability for any tax year, as assessed under Section 903 prior to January 1, 1999, was computed in a manner contrary to the provisions of paragraphs (B-1) or (B-2), no refund shall be payable to the taxpayer for that tax year to the extent such refund is the result of applying the provisions of paragraph (B-1) or (B-2) retroactively. In the case of a unitary business group, such election shall apply to all members of such group for every tax year such group is in existence, but shall not apply to any taxpayer for any period during which that taxpayer is not a member of such group.

(b) Insurance companies.

(1) In general. Except as otherwise provided by paragraph (2), business income of an insurance company for a taxable year shall be apportioned to this State by multiplying such income by a fraction, the numerator of which is the direct premiums written for insurance upon property or risk in this State, and the denominator of which is the direct premiums written for insurance upon property or risk everywhere. For purposes of this subsection, the term "direct premiums written" means the total amount of direct premiums written, assessments and annuity considerations as reported for the taxable year on the annual statement filed by the company with the Illinois Director of Insurance in the form approved by the National Convention of Insurance Commissioners or such other form as may be prescribed in lieu thereof.

(2) Reinsurance. If the principal source of premiums written by an insurance company consists of premiums for reinsurance accepted by it, the business income of such company shall be apportioned to this State by multiplying such income by a fraction, the numerator of which is the sum of (i) direct premiums written for insurance upon property or risk in this State, plus (ii) premiums written for reinsurance accepted in respect of property or risk in this State, and the denominator of which is the sum of (iii) direct premiums written for insurance upon property or risk everywhere, plus (iv) premiums written for reinsurance accepted in respect of property or risk everywhere. For purposes of this paragraph, premiums written for reinsurance accepted in respect of property or risk in this State, whether or not otherwise determinable, may, at the election of the company, be determined on the basis of the proportion which premiums written for reinsurance accepted from companies commercially domiciled in Illinois bears to premiums written for reinsurance accepted from all sources, or, alternatively, in the proportion which the sum of the direct premiums written for insurance upon property or risk in this State by each ceding company from which reinsurance is accepted bears to the sum of the total direct premiums written by each such ceding company for the taxable year. The election made by a company under this paragraph for its first taxable year ending on or after December 31, 2011, shall be binding for that company for that taxable year and for all subsequent taxable years, and may be altered only with the written permission of the Department, which shall not be unreasonably withheld.

(c) Financial organizations.

(1) In general. For taxable years ending before December 31, 2008, business income of a financial organization shall be apportioned to this State by multiplying such income by a fraction, the numerator of which is its business income from sources within this State, and the denominator of which is its business income from all sources. For the purposes of this subsection, the business income of a financial organization from sources within this State is the sum of the amounts referred to in subparagraphs (A) through (E) following, but excluding the adjusted income of an international banking facility as determined in paragraph (2):

(A) Fees, commissions or other compensation for financial services rendered within this State;

(B) Gross profits from trading in stocks, bonds or other securities managed within this State;

(C) Dividends, and interest from Illinois customers, which are received within this State;

(D) Interest charged to customers at places of business maintained within this State for carrying debit balances of margin accounts, without deduction of any costs incurred in carrying such accounts; and

(E) Any other gross income resulting from the operation as a financial organization within this State.

In computing the amounts referred to in paragraphs (A) through (E) of this subsection, any amount received by a member of an affiliated group (determined under Section 1504(a) of the Internal Revenue Code but without reference to whether any such corporation is an "includible corporation" under Section 1504(b) of the Internal Revenue Code) from another member of such group shall be included only to the extent such amount exceeds expenses of the recipient directly related thereto.

(2) International Banking Facility. For taxable years ending before December 31, 2008:

(A) Adjusted Income. The adjusted income of an international banking facility is its income reduced by the amount of the floor amount.

(B) Floor Amount. The floor amount shall be the amount, if any, determined by multiplying the income of the international banking facility by a fraction, not greater than one, which is determined as follows:

(i) The numerator shall be:

The average aggregate, determined on a quarterly basis, of the financial organization's loans to banks in foreign countries, to foreign domiciled borrowers (except where secured primarily by real estate) and to foreign governments and other foreign official institutions, as reported for its branches, agencies and offices within the state on its "Consolidated Report of Condition", Schedule A, Lines 2.c., 5.b., and 7.a., which was filed with the Federal Deposit Insurance Corporation and other regulatory authorities, for the year 1980, minus

The average aggregate, determined on a quarterly basis, of such loans (other than loans of an international banking facility), as reported by the financial institution for its branches, agencies and offices within the state, on the corresponding Schedule and lines of the Consolidated Report of Condition for the current taxable year, provided, however, that in no case shall the amount determined in this clause (the subtrahend) exceed the amount determined in the preceding clause (the minuend); and

(ii) the denominator shall be the average aggregate, determined on a quarterly basis, of the international banking facility's loans to banks in foreign countries, to foreign domiciled borrowers (except where secured primarily by real estate) and to foreign governments and other foreign official institutions, which were recorded in its financial accounts for the current taxable year.

(C) Change to Consolidated Report of Condition and in Qualification. In the event the Consolidated Report of Condition which is filed with the Federal Deposit Insurance Corporation and other regulatory authorities is altered so that the information required for determining the floor amount is not found on Schedule A, lines 2.c., 5.b. and 7.a., the financial institution shall notify the Department and the Department may, by regulations or otherwise, prescribe or authorize the use of an alternative source for such information. The financial institution shall also notify the Department should its international banking facility fail to qualify as such, in whole or in part, or should there be any amendment or change to the Consolidated Report of Condition, as originally filed, to the extent such amendment or change alters the information used in determining the floor amount.

(3) For taxable years ending on or after December 31, 2008, the business income of a financial organization shall be apportioned to this State by multiplying such income by a fraction, the numerator of which is its gross receipts from sources in this State or otherwise attributable to this State's marketplace and the denominator of which is its gross receipts everywhere during the taxable year. "Gross receipts" for purposes of this subparagraph (3) means gross income, including net taxable gain on disposition of assets, including securities and money market instruments, when derived from transactions and activities in the regular course of the financial organization's trade or business. The following examples are illustrative:

(i) Receipts from the lease or rental of real or tangible personal property are in this State if the property is located in this State during the rental period. Receipts from the lease or rental of tangible personal property that is characteristically moving property, including, but not limited to, motor vehicles, rolling stock, aircraft, vessels, or mobile equipment are from sources in this State to the extent that the property is used in this State.

(ii) Interest income, commissions, fees, gains on disposition, and other receipts from assets in the nature of loans that are secured primarily by real estate or tangible personal property are from sources in this State if the security is located in this State.

(iii) Interest income, commissions, fees, gains on disposition, and other receipts from consumer loans that are not secured by real or tangible personal property are from sources in this State if the debtor is a resident of this State.

(iv) Interest income, commissions, fees, gains on disposition, and other receipts from commercial loans and installment obligations that are not secured by real or tangible personal property are from sources in this State if the proceeds of the loan are to be applied in this State. If it cannot be determined where the funds are to be applied, the income and receipts are from sources in this State if the office of the borrower from which the loan was negotiated in the regular course of business is located in this State. If the location of this office cannot be determined, the income and receipts shall be excluded from the numerator and denominator of the sales factor.

(v) Interest income, fees, gains on disposition, service charges, merchant discount income, and other receipts from credit card receivables are from sources in this State if the card charges are regularly billed to a customer in this State.

(vi) Receipts from the performance of services, including, but not limited to, fiduciary, advisory, and brokerage services, are in this State if the services are received in this State within the meaning of subparagraph (a)(3)(C-5)(iv) of this Section.

(vii) Receipts from the issuance of travelers checks and money orders are from sources in this State if the checks and money orders are issued from a location within this State.

(viii) For tax years ending before December 31, 2024, receipts from investment assets and activities and trading assets and activities are included in the receipts factor as follows:

(1) Interest, dividends, net gains (but not less than zero) and other income from investment assets and activities from trading assets and activities shall be included in the receipts factor. Investment assets and activities and trading assets and activities include, but are not limited to: investment securities; trading account assets; federal funds; securities purchased and sold under agreements to resell or repurchase; options; futures contracts; forward contracts; notional principal contracts such as swaps; equities; and foreign currency transactions. With respect to the investment and trading assets and activities described in subparagraphs (A) and (B) of this paragraph, the receipts factor shall include the amounts described in such subparagraphs.

(A) The receipts factor shall include the amount by which interest from federal funds sold and securities purchased under resale agreements exceeds interest expense on federal funds purchased and securities sold under repurchase agreements.

(B) The receipts factor shall include the amount by which interest, dividends, gains and other income from trading assets and activities, including, but not limited to, assets and activities in the matched book, in the arbitrage book, and foreign currency transactions, exceed amounts paid in lieu of interest, amounts paid in lieu of dividends, and losses from such assets and activities.

(2) The numerator of the receipts factor includes interest, dividends, net gains (but not less than zero), and other income from investment assets and activities and from trading assets and activities described in paragraph (1) of this subsection that are attributable to this State.

(A) The amount of interest, dividends, net gains (but not less than zero), and other income from investment assets and activities in the investment account to be attributed to this State and included in the numerator is determined by multiplying all such income from such assets and activities by a fraction, the numerator of which is the gross income from such assets and activities which are properly assigned to a fixed place of business of the taxpayer within this State and the denominator of which is the gross income from all such assets and activities.

(B) The amount of interest from federal funds sold and purchased and from securities purchased under resale agreements and securities sold under repurchase agreements attributable to this State and included in the numerator is determined by multiplying the amount described in subparagraph (A) of paragraph (1) of this subsection from such funds and such securities by a fraction, the numerator of which is the gross income from such funds and such securities which are properly assigned to a fixed place of business of the taxpayer within this State and the denominator of which is the gross income from all such funds and such securities.

(C) The amount of interest, dividends, gains, and other income from trading assets and activities, including, but not limited to, assets and activities in the matched book, in the arbitrage book and foreign currency transactions (but excluding amounts described in subparagraphs (A) or (B) of this paragraph), attributable to this State and included in the numerator is determined by multiplying the amount described in subparagraph (B) of paragraph (1) of this subsection by a fraction, the numerator of which is the gross income from such trading assets and activities which are properly assigned to a fixed place of business of the taxpayer within this State and the denominator of which is the gross income from all such assets and activities.

(D) Properly assigned, for purposes of this paragraph (2) of this subsection, means the investment or trading asset or activity is assigned to the fixed place of business with which it has a preponderance of substantive contacts. An investment or trading asset or activity assigned by the taxpayer to a fixed place of business without the State shall be presumed to have been properly assigned if:

(i) the taxpayer has assigned, in the regular course of its business, such asset or activity on its records to a fixed place of business consistent with federal or state regulatory requirements;

(ii) such assignment on its records is based upon substantive contacts of the asset or activity to such fixed place of business; and

(iii) the taxpayer uses such records reflecting assignment of such assets or activities for the filing of all state and local tax returns for which an assignment of such assets or activities to a fixed place of business is required.

(E) The presumption of proper assignment of an investment or trading asset or activity provided in subparagraph (D) of paragraph (2) of this subsection may be rebutted upon a showing by the Department, supported by a preponderance of the evidence, that the preponderance of substantive contacts regarding such asset or activity did not occur at the fixed place of business to which it was assigned on the taxpayer's records. If the fixed place of business that has a preponderance of substantive contacts cannot be determined for an investment or trading asset or activity to which the presumption in subparagraph (D) of paragraph (2) of this subsection does not apply or with respect to which that presumption has been rebutted, that asset or activity is properly assigned to the state in which the taxpayer's commercial domicile is located. For purposes of this subparagraph (E), it shall be presumed, subject to rebuttal, that taxpayer's commercial domicile is in the state of the United States or the District of Columbia to which the greatest number of employees are regularly connected with the management of the investment or trading income or out of which they are working, irrespective of where the services of such employees are performed, as of the last day of the taxable year.

(ix) For tax years ending on or after December 31, 2024, receipts from investment assets and activities and trading assets and activities are included in the receipts factor as follows:

(1) Interest, dividends, net gains (but not less than zero), and other income from investment assets and activities from trading assets and activities shall be included in the receipts factor. Investment assets and activities and trading assets and activities include, but are not limited to the following: investment securities; trading account assets; federal funds; securities purchased and sold under agreements to resell or repurchase; options; futures contracts; forward contracts; notional principal contracts, such as swaps; equities; and foreign currency transactions. With respect to the investment and trading assets and activities described in subparagraphs (A) and (B) of this paragraph, the receipts factor shall include the amounts described in those subparagraphs.

(A) The receipts factor shall include the amount by which interest from federal funds sold and securities purchased under resale agreements exceeds interest expense on federal funds purchased and securities sold under repurchase agreements.

(B) The receipts factor shall include the amount by which interest, dividends, gains and other income from trading assets and activities, including, but not limited to, assets and activities in the matched book, in the arbitrage book, and foreign currency transactions, exceed amounts paid in lieu of interest, amounts paid in lieu of dividends, and losses from such assets and activities.

(2) The numerator of the receipts factor includes interest, dividends, net gains (but not less than zero), and other income from investment assets and activities and from trading assets and activities described in paragraph (1) of this subsection that are attributable to this State.

(A) The amount of interest, dividends, net gains (but not less than zero), and other income from investment assets and activities in the investment account to be attributed to this State and included in the numerator is determined by multiplying all of the income from those assets and activities by a fraction, the numerator of which is the total receipts included in the numerator pursuant to items (i) through (vii) of this subparagraph (3) and the denominator of which is all total receipts included in the denominator, other than interest, dividends, net gains (but not less than zero), and other income from investment assets and activities and trading assets and activities.

(B) The amount of interest from federal funds sold and purchased and from securities purchased under resale agreements and securities sold under repurchase agreements attributable to this State and included in the numerator is determined by multiplying the amount described in subparagraph (A) of paragraph (1) of this subsection from such funds and such securities by a fraction, the numerator of which is the total receipts included in the numerator pursuant to items (i) through (vii) of this subparagraph (3) and the denominator of which is all total receipts included in the denominator, other than interest, dividends, net gains (but not less than zero), and other income from investment assets and activities and trading assets and activities.

(C) The amount of interest, dividends, gains, and other income from trading assets and activities, including, but not limited to, assets and activities in the matched book, in the arbitrage book and foreign currency transactions (but excluding amounts described in subparagraphs (A) or (B) of this paragraph), attributable to this State and included in the numerator is determined by multiplying the amount described in subparagraph (B) of paragraph (1) of this subsection by a fraction, the numerator of which is the total receipts included in the numerator pursuant to items (i) through (vii) of this subparagraph (3) and the denominator of which is all total receipts included in the denominator, other than interest, dividends, net gains (but not less than zero), and other income from investment assets and activities and trading assets and activities.

(4) (Blank).

(5) (Blank).

(c-1) Federally regulated exchanges. For taxable years ending on or after December 31, 2012, business income of a federally regulated exchange shall, at the option of the federally regulated exchange, be apportioned to this State by multiplying such income by a fraction, the numerator of which is its business income from sources within this State, and the denominator of which is its business income from all sources. For purposes of this subsection, the business income within this State of a federally regulated exchange is the sum of the following:

(1) Receipts attributable to transactions executed on a physical trading floor if that physical trading floor is located in this State.

(2) Receipts attributable to all other matching, execution, or clearing transactions, including without limitation receipts from the provision of matching, execution, or clearing services to another entity, multiplied by (i) for taxable years ending on or after December 31, 2012 but before December 31, 2013, 63.77%; and (ii) for taxable years ending on or after December 31, 2013, 27.54%.

(3) All other receipts not governed by subparagraphs (1) or (2) of this subsection (c-1), to the extent the receipts would be characterized as "sales in this State" under item (3) of subsection (a) of this Section.

"Federally regulated exchange" means (i) a "registered entity" within the meaning of 7 U.S.C. Section 1a(40)(A), (B), or (C), (ii) an "exchange" or "clearing agency" within the meaning of 15 U.S.C. Section 78c (a)(1) or (23), (iii) any such entities regulated under any successor regulatory structure to the foregoing, and (iv) all taxpayers who are members of the same unitary business group as a federally regulated exchange, determined without regard to the prohibition in Section 1501(a)(27) of this Act against including in a unitary business group taxpayers who are ordinarily required to apportion business income under different subsections of this Section; provided that this subparagraph (iv) shall apply only if 50% or more of the business receipts of the unitary business group determined by application of this subparagraph (iv) for the taxable year are attributable to the matching, execution, or clearing of transactions conducted by an entity described in subparagraph (i), (ii), or (iii) of this paragraph.

In no event shall the Illinois apportionment percentage computed in accordance with this subsection (c-1) for any taxpayer for any tax year be less than the Illinois apportionment percentage computed under this subsection (c-1) for that taxpayer for the first full tax year ending on or after December 31, 2013 for which this subsection (c-1) applied to the taxpayer.

(d) Transportation services. For taxable years ending before December 31, 2008, business income derived from furnishing transportation services shall be apportioned to this State in accordance with paragraphs (1) and (2):

(1) Such business income (other than that derived from transportation by pipeline) shall be apportioned to this State by multiplying such income by a fraction, the numerator of which is the revenue miles of the person in this State, and the denominator of which is the revenue miles of the person everywhere. For purposes of this paragraph, a revenue mile is the transportation of 1 passenger or 1 net ton of freight the distance of 1 mile for a consideration. Where a person is engaged in the transportation of both passengers and freight, the fraction above referred to shall be determined by means of an average of the passenger revenue mile fraction and the freight revenue mile fraction, weighted to reflect the person's

(A) relative railway operating income from total passenger and total freight service, as reported to the Interstate Commerce Commission, in the case of transportation by railroad, and

(B) relative gross receipts from passenger and freight transportation, in case of transportation other than by railroad.

(2) Such business income derived from transportation by pipeline shall be apportioned to this State by multiplying such income by a fraction, the numerator of which is the revenue miles of the person in this State, and the denominator of which is the revenue miles of the person everywhere. For the purposes of this paragraph, a revenue mile is the transportation by pipeline of 1 barrel of oil, 1,000 cubic feet of gas, or of any specified quantity of any other substance, the distance of 1 mile for a consideration.

(3) For taxable years ending on or after December 31, 2008, business income derived from providing transportation services other than airline services shall be apportioned to this State by using a fraction, (a) the numerator of which shall be (i) all receipts from any movement or shipment of people, goods, mail, oil, gas, or any other substance (other than by airline) that both originates and terminates in this State, plus (ii) that portion of the person's gross receipts from movements or shipments of people, goods, mail, oil, gas, or any other substance (other than by airline) that originates in one state or jurisdiction and terminates in another state or jurisdiction, that is determined by the ratio that the miles traveled in this State bears to total miles everywhere and (b) the denominator of which shall be all revenue derived from the movement or shipment of people, goods, mail, oil, gas, or any other substance (other than by airline). Where a taxpayer is engaged in the transportation of both passengers and freight, the fraction above referred to shall first be determined separately for passenger miles and freight miles. Then an average of the passenger miles fraction and the freight miles fraction shall be weighted to reflect the taxpayer's:

(A) relative railway operating income from total passenger and total freight service, as reported to the Surface Transportation Board, in the case of transportation by railroad; and

(B) relative gross receipts from passenger and freight transportation, in case of transportation other than by railroad.

(4) For taxable years ending on or after December 31, 2008, business income derived from furnishing airline transportation services shall be apportioned to this State by multiplying such income by a fraction, the numerator of which is the revenue miles of the person in this State, and the denominator of which is the revenue miles of the person everywhere. For purposes of this paragraph, a revenue mile is the transportation of one passenger or one net ton of freight the distance of one mile for a consideration. If a person is engaged in the transportation of both passengers and freight, the fraction above referred to shall be determined by means of an average of the passenger revenue mile fraction and the freight revenue mile fraction, weighted to reflect the person's relative gross receipts from passenger and freight airline transportation.

(e) Combined apportionment. Where 2 or more persons are engaged in a unitary business as described in subsection (a)(27) of Section 1501, a part of which is conducted in this State by one or more members of the group, the business income attributable to this State by any such member or members shall be apportioned by means of the combined apportionment method. For purposes of applying this Section, for tax years ending on or after December 31, 2025, sales of each member of the unitary business group, as defined in paragraph (27) of subsection (a) of Section 1501, who is not a taxpayer, as defined in paragraph (24) of subsection (a) Section 1501, shall be determined based upon the apportionment rules applicable to the member and shall be aggregated. Each taxpayer member of the unitary business group shall include in its sales factor numerator a portion of the aggregate Illinois sales of non-taxpayer members based on a ratio, the numerator of which is that taxpayer member's Illinois sales taking into account its applicable sales factor provisions, and the denominator of which is the aggregate Illinois sales of all the taxpayer members of the group taking into account their respective sales factor provisions. In addition, if inclusion of sales in the sales factor or numerator of the sales factor depends on whether a taxpayer is considered taxable in another state within the meaning of subsection (f) of Section 303, that taxpayer shall be considered taxable in any state in which any member of its unitary business group is considered taxable under subsection (f) of Section 303.

(f) Alternative allocation. If the allocation and apportionment provisions of subsections (a) through (e) and of subsection (h) do not, for taxable years ending before December 31, 2008, fairly represent the extent of a person's business activity in this State, or, for taxable years ending on or after December 31, 2008, fairly represent the market for the person's goods, services, or other sources of business income, the person may petition for, or the Director may, without a petition, permit or require, in respect of all or any part of the person's business activity, if reasonable:

(1) Separate accounting;

(2) The exclusion of any one or more factors;

(3) The inclusion of one or more additional factors which will fairly represent the person's business activities or market in this State; or

For purposes of applying subparagraphs (B) or (C) of this paragraph to all of those years, the election allowed by this subparagraph applies only to the taxpayer making the election and to those members of the taxpayer's unitary business group who are ordinarily required to apportion business income under the same subsection of Section 304 of this Act as the taxpayer making the election. No election allowed by this subparagraph shall be made under a claim filed under subsection (d) of Section 909 more than 30 days after the effective date of this amendatory Act of 1996.

(F) Finance Leases. For purposes of this subsection, a finance lease shall be treated as a loan or other extension of credit, rather than as a lease, regardless of how the transaction is characterized for any other purpose, including the purposes of any regulatory agency to which the lessor is subject.

(A) The term "unitary business group" means a group of persons related through common ownership whose business activities are integrated with, dependent upon and contribute to each other. For taxable years ending before January 1, 2027, the The group will not include those members whose business activity outside the United States is 80% or more of any such member's total business activity; for purposes of this paragraph and clause (a)(3)(B)(ii) of Section 304, business activity within the United States shall be measured by means of the factors ordinarily applicable under subsections (a), (b), (c), (d), or (h) of Section 304 except that, in the case of members ordinarily required to apportion business income by means of the 3 factor formula of property, payroll and sales specified in subsection (a) of Section 304, including the formula as weighted in subsection (h) of Section 304, such members shall not use the sales factor in the computation and the results of the property and payroll factor computations of subsection (a) of Section 304 shall be divided by 2 (by one if either the property or payroll factor has a denominator of zero). The computation required by the preceding sentence shall, in each case, involve the division of the member's property, payroll, or revenue miles in the United States, insurance premiums on property or risk in the United States, or financial organization business income from sources within the United States, as the case may be, by the respective worldwide figures for such items. Common ownership in the case of corporations is the direct or indirect control or ownership of more than 50% of the outstanding voting stock of the persons carrying on unitary business activity. Unitary business activity can ordinarily be illustrated where the activities of the members are: (1) in the same general line (such as manufacturing, wholesaling, retailing of tangible personal property, insurance, transportation or finance); or (2) are steps in a vertically structured enterprise or process (such as the steps involved in the production of natural resources, which might include exploration, mining, refining, and marketing); and, in either instance, the members are functionally integrated through the exercise of strong centralized management (where, for example, authority over such matters as purchasing, financing, tax compliance, product line, personnel, marketing and capital investment is not left to each member).

(B) In no event, for taxable years ending prior to December 31, 2017, shall any unitary business group include members which are ordinarily required to apportion business income under different subsections of Section 304 except that for tax years ending on or after December 31, 1987 this prohibition shall not apply to a holding company that would otherwise be a member of a unitary business group with taxpayers that apportion business income under any of subsections (b), (c), (c-1), or (d) of Section 304. If a unitary business group would, but for the preceding sentence, include members that are ordinarily required to apportion business income under different subsections of Section 304, then for each subsection of Section 304 for which there are two or more members, there shall be a separate unitary business group composed of such members. For purposes of the preceding two sentences, a member is "ordinarily required to apportion business income" under a particular subsection of Section 304 if it would be required to use the apportionment method prescribed by such subsection except for the fact that it derives business income solely from Illinois. As used in this paragraph, for taxable years ending before December 31, 2017, the phrase "United States" means only the 50 states and the District of Columbia, but does not include any territory or possession of the United States or any area over which the United States has asserted jurisdiction or claimed exclusive rights with respect to the exploration for or exploitation of natural resources. For taxable years ending on or after December 31, 2017, the phrase "United States", as used in this paragraph, means only the 50 states, the District of Columbia, and any area over which the United States has asserted jurisdiction or claimed exclusive rights with respect to the exploration for or exploitation of natural resources, but does not include any territory or possession of the United States.

(C) Holding companies.

(i) For purposes of this subparagraph, a "holding company" is a corporation (other than a corporation that is a financial organization under paragraph (8) of this subsection (a) of Section 1501 because it is a bank holding company under the provisions of the Bank Holding Company Act of 1956 (12 U.S.C. 1841, et seq.) or because it is owned by a bank or a bank holding company) that owns a controlling interest in one or more other taxpayers ("controlled taxpayers"); that, during the period that includes the taxable year and the 2 immediately preceding taxable years or, if the corporation was formed during the current or immediately preceding taxable year, the taxable years in which the corporation has been in existence, derived substantially all its gross income from dividends, interest, rents, royalties, fees or other charges received from controlled taxpayers for the provision of services, and gains on the sale or other disposition of interests in controlled taxpayers or in property leased or licensed to controlled taxpayers or used by the taxpayer in providing services to controlled taxpayers; and that incurs no substantial expenses other than expenses (including interest and other costs of borrowing) incurred in connection with the acquisition and holding of interests in controlled taxpayers and in the provision of services to controlled taxpayers or in the leasing or licensing of property to controlled taxpayers.

(ii) The income of a holding company which is a member of more than one unitary business group shall be included in each unitary business group of which it is a member on a pro rata basis, by including in each unitary business group that portion of the base income of the holding company that bears the same proportion to the total base income of the holding company as the gross receipts of the unitary business group bears to the combined gross receipts of all unitary business groups (in both cases without regard to the holding company) or on any other reasonable basis, consistently applied.

(iii) A holding company shall apportion its business income under the subsection of Section 304 used by the other members of its unitary business group. The apportionment factors of a holding company which would be a member of more than one unitary business group shall be included with the apportionment factors of each unitary business group of which it is a member on a pro rata basis using the same method used in clause (ii).

(iv) The provisions of this subparagraph (C) are intended to clarify existing law.

(D) If including the base income and factors of a holding company in more than one unitary business group under subparagraph (C) does not fairly reflect the degree of integration between the holding company and one or more of the unitary business groups, the dependence of the holding company and one or more of the unitary business groups upon each other, or the contributions between the holding company and one or more of the unitary business groups, the holding company may petition the Director, under the procedures provided under Section 304(f), for permission to include all base income and factors of the holding company only with members of a unitary business group apportioning their business income under one subsection of subsections (a), (b), (c), or (d) of Section 304. If the petition is granted, the holding company shall be included in a unitary business group only with persons apportioning their business income under the selected subsection of Section 304 until the Director grants a petition of the holding company either to be included in more than one unitary business group under subparagraph (C) or to include its base income and factors only with members of a unitary business group apportioning their business income under a different subsection of Section 304.

(E) If the unitary business group members' accounting periods differ, the common parent's accounting period or, if there is no common parent, the accounting period of the member that is expected to have, on a recurring basis, the greatest Illinois income tax liability must be used to determine whether to use the apportionment method provided in subsection (a) or subsection (h) of Section 304. The prohibition against membership in a unitary business group for taxpayers ordinarily required to apportion income under different subsections of Section 304 does not apply to taxpayers required to apportion income under subsection (a) and subsection (h) of Section 304. The provisions of this amendatory Act of 1998 apply to tax years ending on or after December 31, 1998.
