Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

REVENUE
(35 ILCS 5/) Illinois Income Tax Act.

35 ILCS 5/1001

    (35 ILCS 5/1001) (from Ch. 120, par. 10-1001)
    Sec. 1001. Failure to File Tax Returns.
    (a) Failure to file tax return. In case of failure to file any tax return required under this Act on the date prescribed therefor, (determined with regard to any extensions of time for filing) there shall be added as a penalty the amount prescribed by Section 3-3 of the Uniform Penalty and Interest Act.
    (b) Failure to disclose reportable transaction. Any taxpayer who fails to include on any return or statement any information with respect to a reportable transaction that is required under Section 501(b) of this Act to be included with such return or statement shall pay a penalty in the amount determined under this subsection. Such penalty shall be deemed assessed upon the date of filing of the return for the taxable year in which the taxpayer participates in the reportable transaction. A taxpayer shall not be considered to have complied with the requirements of Section 501(b) of this Act unless the disclosure statement filed with the Department includes all of the information required to be disclosed with respect to a reportable transaction pursuant to Section 6011 of the Internal Revenue Code, the regulations promulgated under that statute, and regulations promulgated by the Department under Section 501(b) of this Act.
        (1) Amount of penalty. Except as provided in
    
paragraph (2), the amount of the penalty under this subsection shall be $15,000 for each failure to comply with the requirements of Section 501(b).
        (2) Increase in penalty for listed transactions. In
    
the case of a failure to comply with the requirements of Section 501(b) with respect to a "listed transaction", the penalty under this subsection shall be $30,000 for each failure.
        (3) Authority to rescind penalty. The
    
Department may rescind all or any portion of any penalty imposed by this subsection with respect to any violation, if:
            (A) the violation is with respect to a reportable
        
transaction other than a listed transaction, and
            (B) rescinding the penalty would promote
        
compliance with the requirements of this Act and effective tax administration.
        A determination made under this subparagraph (3) may
    
be reviewed in any administrative or judicial proceeding.
        (4) Coordination with other penalties. The penalty
    
imposed by this subsection is in addition to any penalty imposed by this Act or the Uniform Penalty and Interest Act. The doubling of penalties and interest authorized by the Illinois Tax Delinquency Amnesty Act (P.A. 93-26) are not applicable to the reportable penalties under subsection (b).
    (c) The total penalty imposed under subsection (b) of this Section with respect to any taxable year shall not exceed 10% of the increase in net income (or reduction in Illinois net loss under Section 207 of this Act) that would result had the taxpayer not participated in any reportable transaction affecting its net income for such taxable year.

35 ILCS 5/1002

    (35 ILCS 5/1002) (from Ch. 120, par. 10-1002)
    Sec. 1002. Failure to Pay Tax.
    (a) Negligence. If any part of a deficiency is due to negligence or intentional disregard of rules and regulations (but without intent to defraud) there shall be added to the tax as a penalty the amount prescribed by Section 3-5 of the Uniform Penalty and Interest Act.
    (b) Fraud. If any part of a deficiency is due to fraud, there shall be added to the tax as a penalty the amount prescribed by Section 3-6 of the Uniform Penalty and Interest Act.
    (c) Nonwillful failure to pay withholding tax. If any employer, without intent to evade or defeat any tax imposed by this Act or the payment thereof, shall fail to make a return and pay a tax withheld by him at the time required by or under the provisions of this Act, such employer shall be liable for such taxes and shall pay the same together with the interest and the penalty provided by Sections 3-2 and 3-3, respectively, of the Uniform Penalty and Interest Act and such interest and penalty shall not be charged to or collected from the employee by the employer.
    (d) Willful failure to collect and pay over tax. Any person required to collect, truthfully account for, and pay over the tax imposed by this Act who willfully fails to collect such tax or truthfully account for and pay over such tax or willfully attempts in any manner to evade or defeat the tax or the payment thereof, shall, in addition to other penalties provided by law, be liable for the penalty imposed by Section 3-7 of the Uniform Penalty and Interest Act.
    (e) Penalties assessable.
        (1) In general. Except as otherwise provided in this
    
Act or the Uniform Penalty and Interest Act, the penalties provided by this Act or by the Uniform Penalty and Interest Act shall be paid upon notice and demand and shall be assessed, collected, and paid in the same manner as taxes and any reference in this Act to the tax imposed by this Act shall be deemed also to refer to penalties provided by this Act or by the Uniform Penalty and Interest Act.
        (2) Procedure for assessing certain penalties. For
    
the purposes of Article 9 any penalty under Section 804(a) or Section 1001 shall be deemed assessed upon the filing of the return for the taxable year.
        (3) Procedure for assessing the penalty for failure
    
to file withholding returns or annual transmittal forms for wage and tax statements. The penalty imposed by Section 1004 will be asserted by the Department's issuance of a notice of deficiency. If taxpayer files a timely protest, the procedures of Section 908 will be followed. If taxpayer does not file a timely protest, the notice of deficiency will constitute an assessment pursuant to subsection (c) of Section 904.
        (4) Assessment of penalty under Section 1005(a).
    
The penalty imposed under Section 1005(a) shall be deemed assessed upon the assessment of the tax to which such penalty relates and shall be collected and paid on notice and demand in the same manner as the tax.
    (f) Determination of deficiency. For purposes of subsections (a) and (b), the amount shown as the tax by the taxpayer upon his return shall be taken into account in determining the amount of the deficiency only if such return was filed on or before the last day prescribed by law for the filing of such return, including any extensions of the time for such filing.

    (a) In general. If any amount of tax imposed by this Act, including tax withheld by an employer, is not paid on or before the date prescribed for payment of such tax (determined without regard to any extensions), interest on such amount shall be paid in the manner and at the rate prescribed in Section 3-2 of the Uniform Penalty and Interest Act for the period from such date to the date of payment of such amount, except that if a waiver of restrictions under Section 907 on the assessment and collection of such amount has been filed, and if notice and demand by the Director for the payment of such amount is not made within 30 days after the filing of such waiver, interest shall not be imposed on such amount for the period beginning immediately after such 30th day and ending with the date of notice and demand.
    (b) Interest treated as tax. Interest prescribed under this Section on any tax, including tax withheld by an employer, or on any penalty, shall be deemed assessed upon the assessment of the tax or penalties to which such interest relates and shall be collected and paid on notice and demand in the same manner as tax. Any reference in this Act to the tax imposed by this Act shall be deemed also to refer to interest imposed by this Section on such tax.
    (c) Exception as to estimated tax. This Section shall not apply to any failure to pay estimated tax required by Section 803.
(Source: P.A. 87-205.)

35 ILCS 5/1004

    (35 ILCS 5/1004) (from Ch. 120, par. 10-1004)

(Source: P.A. 87-205.)

35 ILCS 5/1005

    (35 ILCS 5/1005) (from Ch. 120, par. 10-1005)
    Sec. 1005. Penalty for Underpayment of Tax.
    (a) In general. If any amount of tax required to be shown on a return prescribed by this Act is not paid on or before the date required for filing such return (determined without regard to any extension of time to file), a penalty shall be imposed in the manner and at the rate prescribed by the Uniform Penalty and Interest Act.
    (b) Reportable transaction penalty. If a taxpayer has a reportable transaction understatement for any taxable year, there shall be added to the tax an amount equal to 20% of the amount of that understatement. This penalty shall be deemed assessed upon the assessment of the tax to which such penalty relates and shall be collected and paid on notice and demand in the same manner as the tax.
        (1) Reportable transaction understatement.
    
For purposes of this Section, the term "reportable transaction understatement" means the sum of subparagraphs (A) and (B):
            (A) The product of (i) the amount of the increase
        
(if any) in Illinois net income, as determined by reference to the amount of post-apportioned income that results from a difference between the proper tax treatment of an item to which this subsection applies and the taxpayer's treatment of that item (as shown on the taxpayer's return of tax), including an amended return filed prior to the date the taxpayer is first contacted by the Department regarding the examination of the return, and (ii) the applicable tax rates under Section 201 of this Act.
            (B) Special rules in the case of carrybacks and
        
carryovers. The penalty for an understatement of income attributable to a reportable transaction applies to any portion of an understatement for a year to which a loss, deduction, or credit is carried that is attributable to a reportable transaction for that year in which the carryback or carryover of the loss, deduction, or credit arises (the "loss or credit year").
        (2) Items to which subsection applies.
    
This subsection shall apply to any item which is attributable to either of the following: (i) any listed transaction as defined in Treasury Regulations Section 1.6011-4, and (ii) any reportable transaction as defined in Treasury Regulations Section 1.6011-4 (other than a listed transaction) if a significant purpose of the transaction is the avoidance or evasion of federal income tax.
        (3) Subsection (b) shall be applied by
    
substituting "30%" for "20%" with respect to the portion of any reportable transaction understatement with respect to which the requirements of (4)(B)(i) of this subsection are not met.
        (4) Reasonable cause exception.
            (A) In general. No penalty shall be
        
imposed under this subsection with respect to any portion of a reportable transaction understatement if it is shown that there was a reasonable cause for such portion and that the taxpayer acted in good faith with respect to such portion.
            (B) Special rules. Subparagraph (A) does
        
not apply to any reportable transaction (including listed transaction) unless all of the following requirements are met:
                (i) The relevant facts affecting the tax
            
treatment of the item are adequately disclosed in accordance with Section 501(b) of this Act. A taxpayer failing to adequately disclose in accordance with Section 501(b) shall be treated as meeting the requirements of this subparagraph (i) if the penalty for that failure was rescinded under Section 1001(b)(3) of this Act;
                (ii) There is or was substantial authority
            
for such treatment; and
                (iii) The taxpayer reasonably believed that
            
such treatment was more likely than not the proper treatment.
            (C) Rules relating to reasonable belief. For
        
purposes of subparagraph (B), a taxpayer shall be treated as having a reasonable belief with respect to the tax treatment of an item only if such belief meets the requirements of this subparagraph (C):
                (i) Such belief must be based on the facts
            
and law that exist at the time the return of tax that includes that tax treatment is filed;
                (ii) Such belief must relate solely to the
            
taxpayer's chances of success on the merits of that treatment and does not take into account the possibility that the return will not be audited, that the treatment will not be raised on audit, or that the treatment will be resolved through settlement if it is raised; and
                (iii) Such belief is not solely based on the
            
opinion of a disqualified tax advisor or on a disqualified opinion.
        (5) Definitions.
            (A) Disqualified tax advisor. The term
        
"disqualified tax advisor" is a tax advisor that meets any of the following conditions:
                (I) Is a material advisor who participates in
            
the organization, management, promotion, or sale of the transaction or who is related (within the meaning of Sections 267(b) or 707(b)(1) of the Internal Revenue Code) to any person who so participates;
                (II) Is compensated directly or indirectly by
            
a material advisor with respect to the transaction;
                (III) Has a fee arrangement with respect to
            
the transaction that is contingent on all or part of the intended tax benefits from the transaction being sustained; or
                (IV) As determined under regulations
            
prescribed by either the Secretary of the Treasury for federal income tax purposes or the Department, has a continuing financial interest with respect to the transaction.
            (B) Disqualified opinion. The term
        
"disqualified opinion" means an opinion that meets any of the following conditions:
                (I) Is based on unreasonable factual or legal
            
assumptions (including assumptions as to future events);
                (II) Unreasonably relies on representations,
            
statements, findings, or agreements of the taxpayer or any other person;
                (III) Does not identify and consider all
            
relevant facts; or
                (IV) Fails to meet any other requirement as
            
either the Secretary of the Treasury for federal income tax purposes or the Department may prescribe.
            (C) Material Advisor. The term "material
        
advisor" shall have substantially the same meaning as the same term is defined under Treasury Regulations Section 301.6112-1, (26 CFR 301.6112-1) and shall include any person that is a material advisor for federal income tax purposes under such regulation.
        (6) Effective date. This subsection shall
    
apply to taxable years ending on and after December 31, 2004, except that a reportable transaction understatement shall include an understatement (as determined under paragraph (1)) with respect to any taxable year for which the limitations period on assessment has not expired as of January 1, 2005 that is attributable to a transaction which the taxpayer has entered into after February 28, 2000 and before December 31, 2004 that becomes a listed transaction (as defined in Treasury Regulations Section 1.6011-4(b)(2) at any time.
    (c) 100% interest penalty. If a taxpayer has been contacted by the Internal Revenue Service or the Department regarding the use of a potential tax avoidance transaction with respect to a taxable year and has a deficiency with respect to such taxable year or years, there shall be added to the tax attributable to the potential tax avoidance transaction (determined as described in subsection (b)(1) of Section 1005) an amount equal to 100% of the interest assessed under the Uniform Penalty and Interest Act (determined without regard to subsection (f) of Section 3-2 of such Act) for the period beginning on the last date prescribed by law for the payment of such tax and ending on the date of the notice of deficiency. Such penalty shall be deemed assessed upon the assessment of the interest to which such penalty relates and shall be collected and paid in the same manner as such interest. The penalty imposed by this subsection is in addition to any penalty imposed by this Act or the Uniform Penalty and Interest Act. For purposes of this subsection and subsection (d) of this Section, the term "potential tax avoidance transaction" means any tax shelter as defined in Section 6111 of the Internal Revenue Code. This subsection shall apply to taxable years ending on and after December 31, 2004, except that the penalty may also be imposed with respect to any taxable year for which the limitations period on assessment has not expired as of January 1, 2005 that is attributable to a transaction in which the taxpayer has entered into after February 28, 2000 and before December 31, 2004, which transaction becomes a listed transaction (as defined in Treasury Regulations Section 1.6011-4(b)(2)) at any time.
    (d) 150% interest rate. For taxable years ending on and after July 1, 2002, for any notice of deficiency issued before the taxpayer is contacted by the Internal Revenue Service or the Department regarding a potential tax avoidance transaction, the taxpayer is subject to interest as provided under Section 3-2 of the Uniform Penalty and Interest Act, but with respect to any deficiency attributable to a potential tax avoidance transaction, the taxpayer is subject to interest at a rate of 150% of the otherwise applicable rate.
    (e) Coordination with other penalties. Except as provided in regulations, the penalties imposed by this Section are in addition to any other penalty imposed by this Act or the Uniform Penalty and Interest Act. The doubling of penalties and interest authorized by the Illinois Tax Delinquency Amnesty Act (P.A. 93-26), are not applicable to the reportable transaction penalties and interest under subsections (b), (c), and (d).

    Sec. 1006. Frivolous Returns. In addition to any other penalty provided by this Act there is imposed a penalty of $500 upon any individual who files a purported return that does not contain information from which the substantial correctness of the stated tax liability can be determined or contains information indicating that the stated tax liability is substantially incorrect and such conduct is due to a desire to delay or impede the administration of this Act or is due to a position that is frivolous.

transaction under subsection (c) of Section 1405.6, the penalty shall be $100,000.
    (c) Authority to rescind penalty. The Department may rescind all or any portion of any penalty imposed by this subsection with respect to any violation, if
        (1) the violation is with respect to a reportable
    
transaction other than a listed transaction, and
        (2) rescinding the penalty would promote compliance
    
with the requirements of this Act and effective tax administration.

    (35 ILCS 5/1008)

Except as herein provided, the provisions of Section 6700 of the Internal Revenue Code shall apply for purposes of this Act as if such Section applied to an Illinois deduction, credit, exclusion from income, allocation or apportionment rule, or other Illinois tax benefit. Notwithstanding Section 6700(a) of the Internal Revenue Code, if an activity with respect to which a penalty imposed under Section 6700(a) of the Internal Revenue Code, as applied for purposes of this Act, involves a statement described in Section 6700(a)(2)(A) of the Internal Revenue Code, as applied for purposes of this Act, the amount of the penalty imposed under this Section shall be the greater of $10,000 or 50% of the gross income received (or to be received) from any person to whom such statement is furnished that is required to file a return under Section 502 of this Act.

ARTICLE 11. LIENS AND JEOPARDY ASSESSMENT.

35 ILCS 5/1101

    (35 ILCS 5/1101) (from Ch. 120, par. 11-1101)
    Sec. 1101. Lien for Tax.
    (a) If any person liable to pay any tax neglects or refuses to pay the same after demand, the amount (including any interest, additional amount, addition to tax, or assessable penalty, together with any costs that may accrue in addition thereto) shall be a lien in favor of the State of Illinois upon all property and rights to property, whether real or personal, belonging to such person.
    (b) Unless another date is specifically fixed by law, the lien imposed by subsection (a) of this Section shall arise at the time the assessment is made and shall continue until the liability for the amount so assessed (or a judgment against the taxpayer arising out of such liability) is satisfied or becomes unenforceable by reason of lapse of time.
    (c) Deficiency procedure. If the lien arises from an assessment pursuant to a notice of deficiency, such lien shall not attach and the notice referred to in this Section shall not be filed until all proceedings in court for review of such assessment have terminated or the time for the taking thereof has expired without such proceedings being instituted.
    (d) Notice of lien. The lien created by assessment shall terminate unless a notice of lien is filed, as provided in Section 1103 hereof, within 3 years from the date all proceedings in court for the review of such assessment have terminated or the time for the taking thereof has expired without such proceedings being instituted. Where the lien results from the filing of a return without payment of the tax or penalty shown therein to be due, the lien shall terminate unless a notice of lien is filed within 3 years from the date such return was filed with the Department. For the purposes of this subsection (d), a tax return filed before the last day prescribed by law, including any extension thereof, shall be deemed to have been filed on such last day. The time limitation period on the Department's right to file a notice of lien shall not run (1) during any period of time in which the order of any court has the effect of enjoining or restraining the Department from filing such notice of lien, or (2) during the term of a repayment plan that taxpayer has entered into with the Department, as long as taxpayer remains in compliance with the terms of the repayment plan.

35 ILCS 5/1102

    (35 ILCS 5/1102) (from Ch. 120, par. 11-1102)
    Sec. 1102. Jeopardy assessments.
    (a) Jeopardy assessment and lien.
        (1) Assessment. If the Department finds that a
    
taxpayer is about to depart from the State, or to conceal himself or his property, or to do any other act tending to prejudice or to render wholly or partly ineffectual proceedings to collect any amount of tax or penalties imposed under this Act unless court proceedings are brought without delay, or if the Department finds that the collection of such amount will be jeopardized by delay, the Department shall give the taxpayer notice of such findings and shall make demand for immediate return and payment of such amount, whereupon such amount shall be deemed assessed and shall become immediately due and payable.
        (2) Filing of lien. If the taxpayer, within 5 days
    
after such notice (or within such extension of time as the Department may grant), does not comply with such notice or show to the Department that the findings in such notice are erroneous, the Department may file a notice of jeopardy assessment lien in the State Tax Lien Registry and shall notify the taxpayer of such filing. Such jeopardy assessment lien shall have the same scope and effect as a statutory lien under this Act. The taxpayer is liable for any administrative fee imposed by the Department by rule in connection with the State Tax Lien Registry. The filing fees shall be paid to the Department in addition to payment of the tax, penalty, and interest included in the amount of the lien.
    (b) Termination of taxable year. In the case of a tax for a current taxable year, the Director shall declare the taxable period of the taxpayer immediately terminated and his notice and demand for a return and immediate payment of the tax shall relate to the period declared terminated, including therein income accrued and deductions incurred up to the date of termination if not otherwise properly includible or deductible in respect of such taxable year.
    (c) Protest. If the taxpayer believes that he does not owe some or all of the amount for which the jeopardy assessment lien against him has been filed, or that no jeopardy to the revenue in fact exists, he may protest within 20 days after being notified by the Department of the filing of such jeopardy assessment lien and request a hearing, whereupon the Department shall hold a hearing in conformity with the provisions of Section 908 and, pursuant thereto, shall notify the taxpayer of its decision as to whether or not such jeopardy assessment lien will be released.

    (35 ILCS 5/1103) (from Ch. 120, par. 11-1103)
    Sec. 1103. Filing and priority of liens.
    (a) Filing in the State Tax Lien Registry. Nothing in this Article shall be construed to give the Department a preference over the rights of any bona fide purchaser, holder of a security interest, mechanics lienor, mortgagee, or judgment lien creditor arising prior to the filing of a regular notice of lien or a notice of jeopardy assessment lien in the State Tax Lien Registry. For purposes of this Section, the term "bona fide," shall not include any mortgage of real or personal property or any other credit transaction that results in the mortgagee or the holder of the security acting as trustee for unsecured creditors of the taxpayer mentioned in the notice of lien who executed such chattel or real property mortgage or the document evidencing such credit transaction. Such lien shall be inferior to the lien of general taxes, special assessments and special taxes heretofore or hereafter levied by any political subdivision of this State.
    (b) Filing in the State Tax Lien Registry. In case title to land to be affected by the notice of lien or notice of jeopardy assessment lien is registered under the provisions of "An Act concerning land titles," approved May 1, 1897, as amended, such notice shall also be filed in the State Tax Lien Registry, and the Department shall not have a preference over the rights of any bona fide purchaser, mortgagee, judgment creditor or other lien holder arising prior to the registration of such notice.
    (c) Index. The Department of Revenue shall maintain a State Tax Lien Index of all tax liens filed in the State Tax Lien Registry as provided for by the State Tax Lien Registration Act.
    (d) (Blank).
    (e) The taxpayer is liable for any filing fees imposed by the Department for filing the lien in the State Tax Lien Registry and any filing fees imposed by the Department for the release of that lien. The filing fees shall be paid to the Department in addition to payment of the tax, penalty, and interest included in the amount of the lien.

The lien provided herein shall continue for 20 years from the date of filing the notice of lien under the provisions of section 1103 unless sooner released, or otherwise discharged.

    (35 ILCS 5/1105) (from Ch. 120, par. 11-1105)
    Sec. 1105. Release of liens.
    (a) In general. Upon payment by the taxpayer to the Department in cash or by guaranteed remittance of an amount representing the filing fees and charges for the lien and the filing fees and charges for the release of that lien, the Department shall release all or any portion of the property subject to any lien provided for in this Act and file that complete or partial release of lien in the State Tax Lien Registry if it determines that the release will not endanger or jeopardize the collection of the amount secured thereby.
    (b) Judicial determination. If on judicial review the final judgment of the court is that the taxpayer does not owe some or all of the amount secured by the lien against him, or that no jeopardy to the revenue exists, the Department shall release its lien to the extent of such finding of nonliability, or to the extent of such finding of no jeopardy to the revenue. The taxpayer shall, however, be liable for the filing fee imposed by the Department to file the lien and the filing fee imposed to release the lien. The filing fees shall be paid to the Department.
    (c) Payment. The Department shall also release its jeopardy assessment lien against the taxpayer whenever the tax and penalty covered by such lien, plus any interest which may be due and an amount representing the filing fee to file the lien and the filing fee imposed to release that lien, are paid by the taxpayer to the Department in cash or by guaranteed remittance.
    (d) Certificate of release. The Department shall issue a certificate of complete or partial release of the lien upon payment by the taxpayer to the Department in cash or by guaranteed remittance of an amount representing the filing fee imposed by the Department to file the lien and the filing fee imposed to release that lien:
        (1) to the extent that the fair market value of any
    
property subject to the lien exceeds the amount of the lien plus the amount of all prior liens upon such property;
        (2) to the extent that such lien shall become
    
unenforceable;
        (3) to the extent that the amount of such lien is
    
paid by the person whose property is subject to such lien, together with any interest and penalty which may become due under this Act between the date when the notice of lien is filed and the date when the amount of such lien is paid;
        (4) to the extent that there is furnished to the
    
Department on a form to be approved and with a surety or sureties satisfactory to the Department a bond that is conditioned upon the payment of the amount of such lien, together with any interest which may become due under this Act after the notice of lien is filed, but before the amount thereof is fully paid;
        (5) to the extent and under the circumstances
    
specified in this Section.
    A certificate of complete or partial release of any lien shall be held conclusive that the lien upon the property covered by the certificate is extinguished to the extent indicated by such certificate.
    Such release of lien shall be issued to the person, or his agent, against whom the lien was obtained and shall contain in legible letters a statement as follows:
    FOR THE PROTECTION OF THE OWNER, THIS RELEASE SHALL
    BE FILED IN THE STATE TAX LIEN REGISTRY.
    (e) Filing. When a certificate of complete or partial release of lien issued by the Department is filed in the State Tax Lien Registry, the Department shall permanently attach the certificate of release to the notice of lien or notice of jeopardy assessment lien and shall enter the certificate of release and the date in the "State Tax Lien Index" on the line where the notice of lien or notice of jeopardy assessment lien is entered.

    (35 ILCS 5/1109) (from Ch. 120, par. 11-1109)
    Sec. 1109. Demand and Seizure. In addition to any other remedy provided for by the laws of this State, if the tax imposed by this Act is not paid within the time required by this Act, the Department, or some person designated by it, may cause a demand to be made on the taxpayer for the payment thereof. If such tax remains unpaid for 10 days after such demand has been made and no proceedings have been taken to review the same, the Department may issue a warrant directed to any sheriff or other person authorized to serve process, commanding the sheriff or other person to levy upon the property and rights to property (whether real or personal, tangible or intangible) of the taxpayer, without exemption, found within his jurisdiction, for the payment of the amount thereof with the added penalties, interest and the cost of executing the warrant. The term "levy" includes the power of distraint and seizure by any means. In any case in which the warrant to levy has been issued, the sheriff or other person to whom the warrant was directed may seize and sell such property or rights to property. Such warrant shall be returned to the Department together with the money collected by virtue thereof within the time therein specified, which shall not be less than 20 nor more than 90 days from the date of the warrant. The sheriff or other person to whom such warrant is directed shall proceed in the same manner as prescribed by law in respect to the enforcement against property upon judgments by a court, and shall be entitled to the same fees for his services in executing the warrant, to be collected in the same manner. The Department, or some officer, employee or agent designated by it, is hereby authorized to bid for and purchase any property sold under the provisions hereof. No proceedings for a levy under this Section shall be commenced more than 20 years after the latest date for filing of the notice of lien under the provisions of Section 1103, without regard to whether such notice was actually filed.
    Any officer or employee of the Department designated in writing by the Director is authorized to serve process under this Section to levy upon accounts or other intangible assets of a taxpayer held by a financial organization, as defined in Section 1501 of this Act. In addition to any other provisions of this Section, any officer or employee of the Department designated in writing by the Director may levy upon the following property and rights to property belonging to a taxpayer: contractual payments, accounts and notes receivable and other evidences of debt, and interest on bonds, by serving a notice of levy on the person making such payment. Levy shall not be made until the Department has caused a demand to be made on the taxpayer in the manner provided above. In addition to any other provisions of this Section, any officer or employee of the Department designated in writing by the Director, may levy upon the salary, wages, commissions and bonuses of any employee, including officers, employees, or elected officials of the United States as authorized by Section 5520a of the Government Organization and Employees Act (5 U.S.C. 5520a), but not upon the salary or wages of officers, employees, or elected officials of any state other than this State, by serving a notice of levy on the employer, as defined in Section 701(d). Levy shall not be made until the Department has caused a demand to be made on the employee in the manner provided above. The provisions of Section 12-803 of the Code of Civil Procedure relating to maximum compensation subject to collection under wage deduction orders shall apply to all levies made upon compensation under this Section. To the extent of the amount due on the levy, the employer or other person making payments to the taxpayer shall hold any non-exempt wages or other payments due or which subsequently come due. The levy or balance due thereon is a lien on wages or other payments due at the time of the service of the notice of levy, and such lien shall continue as to subsequent earnings and other payments until the total amount due upon the levy is paid, except that such lien on subsequent earnings or other payments shall terminate sooner if the employment relationship is terminated or if the notice of levy is rescinded or modified. The employer or other person making payments to the taxpayer shall file, on or before the return dates stated in the notice of levy (which shall not be more often than bimonthly) a written answer under oath to interrogatories, setting forth the amount due as wages or other payments to the taxpayer for the payment periods ending immediately prior to the appropriate return date. A lien obtained hereunder shall have priority over any subsequent lien obtained pursuant to Section 12-808 of the Code of Civil Procedure, except that liens for the support of a spouse or dependent children shall have priority over all liens obtained hereunder.
    In any case where property or rights to property have been seized by an officer of the Illinois State Police, or successor agency thereto, under the authority of a warrant to levy issued by the Department of Revenue, the Department of Revenue may take possession of and may sell such property or rights to property and the Department of Revenue may contract with third persons to conduct sales of such property or rights to the property. In the conduct of such sales, the Department of Revenue shall proceed in the same manner as is prescribed by law for proceeding against property to enforce judgments which are entered by a circuit court of this State. If, in the Department of Revenue's opinion, no offer to purchase at such sale is acceptable and the State's interest would be better served by retaining the property for sale at a later date, then the Department may decline to accept any bid and may retain the property for sale at a later date.

                    (d) more than 50% of all interest-bearing
                
obligations of the affiliated group payable to persons outside the group determined in accordance with generally accepted accounting principles must be obligations of the corporation.

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.

calendar year, or the fiscal year ending during such calendar year, upon the basis of which the base income is computed under this Act. "Taxable year" means, in the case of a return made for a fractional part of a year under the provisions of this Act, the period for which such return is made.
        (24) Taxpayer. The term "taxpayer" means any person
    
subject to the tax imposed by this Act.
        (25) International banking facility. The term
    
international banking facility shall have the same meaning as is set forth in the Illinois Banking Act or as is set forth in the laws of the United States or regulations of the Board of Governors of the Federal Reserve System.
        (26) Income Tax Return Preparer.
            (A) The term "income tax return preparer" means
        
any person who prepares for compensation, or who employs one or more persons to prepare for compensation, any return of tax imposed by this Act or any claim for refund of tax imposed by this Act. The preparation of a substantial portion of a return or claim for refund shall be treated as the preparation of that return or claim for refund.
            (B) A person is not an income tax return preparer
        
if all he or she does is
                (i) furnish typing, reproducing, or other
            
mechanical assistance;
                (ii) prepare returns or claims for refunds
            
for the employer by whom he or she is regularly and continuously employed;
                (iii) prepare as a fiduciary returns or
            
claims for refunds for any person; or
                (iv) prepare claims for refunds for a
            
taxpayer in response to any notice of deficiency issued to that taxpayer or in response to any waiver of restriction after the commencement of an audit of that taxpayer or of another taxpayer if a determination in the audit of the other taxpayer directly or indirectly affects the tax liability of the taxpayer whose claims he or she is preparing.
        (27) Unitary business group.
            (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. 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.
        (28) Subchapter S corporation. The term "Subchapter
    
S corporation" means a corporation for which there is in effect an election under Section 1362 of the Internal Revenue Code, or for which there is 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.
        (30) Foreign person. The term "foreign person" means
    
any person who is a nonresident individual who is a national or citizen of a country other than the United States and any nonindividual entity, regardless of where created or organized, whose business activity outside the United States is 80% or more of the entity's total business activity.
    (b) Other definitions.
        (1) Words denoting number, gender, and so forth, when
    
used in this Act, where not otherwise distinctly expressed or manifestly incompatible with the intent thereof:
            (A) Words importing the singular include and
        
apply to several persons, parties or things;
            (B) Words importing the plural include the
        
singular; and
            (C) Words importing the masculine gender include
        
the feminine as well.
        (2) "Company" or "association" as including
    
successors and assigns. The word "company" or "association", when used in reference to a corporation, shall be deemed to embrace the words "successors and assigns of such company or association", and in like manner as if these last-named words, or words of similar import, were expressed.
        (3) Other terms. Any term used in any Section of this
    
Act with respect to the application of, or in connection with, the provisions of any other Section of this Act shall have the same meaning as in such other Section.
