(2) Lower Required Installment where Annualized Income Installment is Less Than Amount Determined Under Paragraph (1).

(A) In General. In the case of any required installment if a taxpayer establishes that the annualized income installment is less than the amount determined under paragraph (1),

(i) the amount of such required installment shall be the annualized income installment, and

(ii) any reduction in a required installment resulting from the application of this subparagraph shall be recaptured by increasing the amount of the next required installment determined under paragraph (1) by the amount of such reduction, and by increasing subsequent required installments to the extent that the reduction has not previously been recaptured under this clause.

(B) Determination of Annualized Income Installment. In the case of any required installment, the annualized income installment is the excess, if any, of:

(ii) dividing the resulting amount by the number of months in the taxable year ending before the month in which such installment date falls; and

(iii) deducting from such amount the standard exemption allowable for the taxable year, such standard exemption being determined as of the last date prescribed for payment of the installment.

(E) Annualized Net Income; Corporations. For corporations, net income shall be placed on an annualized basis by multiplying by 12 the taxable income

(i) for the first 3 months of the taxable year, in the case of the installment required to be paid in the 4th month,

(3) Notwithstanding any other provision of this subsection (c), in the case of a federally regulated exchange that elects to apportion its income under Section 304(c-1) of this Act, the amount of each required installment due prior to June 30 of the first taxable year to which the election applies shall be 25% of the tax that would have been shown on the return for that taxable year if the taxpayer had not made such election.

Notwithstanding the provisions of the preceding subsections, the penalty imposed by subsection (a) shall not be imposed if the taxpayer was not required to file an Illinois income tax return for the preceding taxable year, or, for individuals, if the taxpayer had no tax liability for the preceding taxable year and such year was a taxable year of 12 months. The penalty imposed by subsection (a) shall also not be imposed on any underpayments of estimated tax due before the effective date of this amendatory Act of 1998 which underpayments are solely attributable to the change in apportionment from subsection (a) to subsection (h) of Section 304. The provisions of this amendatory Act of 1998 apply to tax years ending on or after December 31, 1998.

(e) The penalty imposed for underpayment of estimated tax by subsection (a) of this Section shall not be imposed to the extent that the Director or his or her designate determines, pursuant to Section 3-8 of the Uniform Penalty and Interest Act that the penalty should not be imposed.

(g) Application of Section in case of tax withheld under Article 7. For purposes of applying this Section:

(1) tax withheld from compensation for the taxable year shall be deemed a payment of estimated tax, and an equal part of such amount shall be deemed paid on each installment date for such taxable year, unless the taxpayer establishes the dates on which all amounts were actually withheld, in which case the amounts so withheld shall be deemed payments of estimated tax on the dates on which such amounts were actually withheld;

(2) amounts timely paid by a partnership, Subchapter S corporation, or trust on behalf of a partner, shareholder, or beneficiary pursuant to subsection (f) of Section 502 or Section 709.5 and claimed as a payment of estimated tax shall be deemed a payment of estimated tax made on the last day of the taxable year of the partnership, Subchapter S corporation, or trust for which the income from the withholding is made was computed; and

(3) all other amounts pursuant to Article 7 shall be deemed a payment of estimated tax on the date the payment is made to the taxpayer of the amount from which the tax is withheld.

(g-5) Amounts withheld under the State Salary and Annuity Withholding Act. An individual who has amounts withheld under paragraph (10) of Section 4 of the State Salary and Annuity Withholding Act may elect to have those amounts treated as payments of estimated tax made on the dates on which those amounts are actually withheld.

Sec. 902. Notice and demand.

(a) In general. Except as provided in subsection (b) the Director shall, as soon as practicable after an amount payable under this Act is deemed assessed (as provided in Section 903), give notice to each person liable for any unpaid portion of such assessment, stating the amount unpaid and demanding payment thereof. In the case of tax deemed assessed with the filing of a return, the Director shall give notice no later than 3 years after the date the return was filed. Upon receipt of any notice and demand there shall be paid at the place and time stated in such notice the amount stated in such notice. Such notice shall be left at the dwelling or usual place of business of such person or shall be sent by mail to the person's last known address.

(b) Judicial review. In the case of a deficiency deemed assessed under Section 903(a)(2) after the filing of a protest, notice and demand shall not be made with respect to such assessment until 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.

(c) Action for recovery of taxes. At any time that the Department might commence proceedings for a levy under Section 1109, regardless of whether a notice of lien was filed under the provisions of Section 1103, it may bring an action in any court of competent jurisdiction within or without this State in the name of the people of this State to recover the amount of any taxes, penalties and interest due and unpaid under this Act. In such action, the certificate of the Department showing the amount of the delinquency shall be prima facie evidence of the correctness of such amount, its assessment and of the compliance by the Department with all the provisions of this Act.

(d) Sales or transfers outside the usual course of business-Report-Payment of Tax - Rights and duties of purchaser or transferee - penalty. If any taxpayer, outside the usual course of his business, sells or transfers the major part of any one or more of (A) the stock of goods which he is engaged in the business of selling, or (B) the furniture or fixtures, or (C) the machinery and equipment, or (D) the real property, of any business that is subject to the provisions of this Act, the purchaser or transferee of such assets shall, no later than 10 business days before the sale or transfer, file a notice of sale or transfer of business assets with the Department disclosing the name and address of the seller or transferor, the name and address of the purchaser or transferee, the date of the sale or transfer, a copy of the sales contract and financing agreements which shall include a description of the property sold or transferred, the amount of the purchase price or a statement of other consideration for the sale or transfer, and the terms for payment of the purchase price, and such other information as the Department may reasonably require. If the purchaser or transferee fails to file the above described notice of sale with the Department within the prescribed time, the purchaser or transferee shall be personally liable to the Department for the amount owed hereunder by the seller or transferor but unpaid, up to the amount of the reasonable value of the property acquired by the purchaser or transferee. The purchaser or transferee shall pay the Department the amount of tax, penalties, and interest owed by the seller or transferor under this Act, to the extent they have not been paid by the seller or transferor. The seller or transferor, or the purchaser or transferee, at least 10 business days before the date of the sale or transfer, may notify the Department of the intended sale or transfer and request the Department to make a determination as to whether the seller or transferor owes any tax, penalty or interest due under this Act. The Department shall take such steps as may be appropriate to comply with such request.

Any order issued by the Department pursuant to this Section to withhold from the purchase price shall be issued within 10 business days after the Department receives notification of a sale as provided in this Section. The purchaser or transferee shall withhold such portion of the purchase price as may be directed by the Department, but not to exceed a minimum amount varying by type of business, as determined by the Department pursuant to regulations, plus twice the outstanding unpaid liabilities and twice the average liability of preceding filings times the number of unfiled returns which were not filed when due, to cover the amount of all tax, penalty, and interest due and unpaid by the seller or transferor under this Act or, if the payment of money or property is not involved, shall withhold the performance of the condition that constitutes the consideration for the sale or transfer. Within 60 business days after issuance of the initial order to withhold, the Department shall provide written notice to the purchaser or transferee of the actual amount of all taxes, penalties and interest then due and whether or not additional amounts may become due as a result of unpaid taxes required to be withheld by an employer, returns which were not filed when due, pending assessments and audits not completed. The purchaser or transferee shall continue to withhold the amount directed to be withheld by the initial order or such lesser amount as is specified by the final withholding order or to withhold the performance of the condition which constitutes the consideration for the sale or transfer until the purchaser or transferee receives from the Department a certificate showing that no unpaid tax, penalty or interest is due from the seller or transferor under this Act.

The purchaser or transferee is relieved of any duty to continue to withhold from the purchase price and of any liability for tax, penalty, or interest due hereunder from the seller or transferor if the Department fails to notify the purchaser or transferee in the manner provided herein of the amount to be withheld within 10 business days after the sale or transfer has been reported to the Department or within 60 business days after issuance of the initial order to withhold, as the case may be. The Department shall have the right to determine amounts claimed on an estimated basis to allow for periods for which returns were not filed when due, pending assessments and audits not completed, however the purchaser or transferee shall be personally liable only for the actual amount due when determined.

If the seller or transferor has failed to pay the tax, penalty, and interest due from him hereunder and the Department makes timely claim therefor against the purchaser or transferee as hereinabove provided, then the purchaser or transferee shall pay to the Department the amount so withheld from the purchase price. If the purchaser or transferee fails to comply with the requirements of this Section, the purchaser or transferee shall be personally liable to the Department for the amount owed hereunder by the seller or transferor up to the amount of the reasonable value of the property acquired by the purchaser or transferee.

Any person who shall acquire any property or rights thereto which, at the time of such acquisition, is subject to a valid lien in favor of the Department, shall be personally liable to the Department for a sum equal to the amount of taxes, penalties and interests, secured by such lien, but not to exceed the reasonable value of such property acquired by him.

Sec. 903. Assessment. (a) In general. (1) Returns. The amount of tax which is shown to be due on the return shall be deemed assessed on the date of filing of the return (including any amended returns showing an increase of tax). In the event that the amount of tax is understated on the taxpayer's return due to a mathematical error, the Department shall notify the taxpayer that the amount of tax in excess of that shown on the return is due and has been assessed. Such notice of additional tax due shall be issued no later than 3 years after the date the return was filed. Such notice of additional tax due shall not be considered a notice of deficiency nor shall the taxpayer have any right of protest. In the case of a return properly filed without the computation of the tax, the tax computed by the Department shall be deemed to be assessed on the date when payment is due.

(2) Notice of deficiency. If a notice of deficiency has been issued, the amount of the deficiency shall be deemed assessed on the date provided in section 904(d) if no protest is filed; or, if a protest is filed, then upon the date when the decision of the Department becomes final.

(3) Federal change. If an amended return or report is filed with the Department pursuant to section 506(b), any deficiency in tax under this Act resulting therefrom shall be deemed to be assessed on the date of filing such report or amended return and such assessment shall be timely notwithstanding any other provisions of this Act.

(4) Payments. Any amount paid as tax or in respect of tax paid under this Act, other than amounts withheld or paid as estimated tax under Articles 7 or 8, shall be deemed assessed upon the date of receipt of payment, notwithstanding any other provisions of this Act.

(b) Limitations on assessment. No deficiency shall be assessed with respect to a taxable year for which a return was filed unless a notice of deficiency for such year was issued not later than the date prescribed in section 905.

Sec. 904. Deficiencies and Overpayments.

(a) Examination of return. As soon as practicable after a return is filed, the Department shall examine it to determine the correct amount of tax. If the Department finds that the amount of tax shown on the return is less than the correct amount, it shall issue a notice of deficiency to the taxpayer which shall set forth the amount of tax and penalties proposed to be assessed. If the Department finds that the tax paid is more than the correct amount, it shall credit or refund the overpayment as provided by Section 909. The findings of the Department under this subsection shall be prima facie correct and shall be prima facie evidence of the correctness of the amount of tax and penalties due.

(b) No return filed. If the taxpayer fails to file a tax return, the Department shall determine the amount of tax due according to its best judgment and information, which amount so fixed by the Department shall be prima facie correct and shall be prima facie evidence of the correctness of the amount of tax due. The Department shall issue a notice of deficiency to the taxpayer which shall set forth the amount of tax and penalties proposed to be assessed.

(c) Notice of deficiency. A notice of deficiency issued under this Act shall set forth the adjustments giving rise to the proposed assessment and the reasons therefor. In the case of a joint return, the notice of deficiency may be a single joint notice except that if the Department is notified by either spouse that separate residences have been established, it shall issue joint notices to each spouse.

(d) Assessment when no protest. Upon the expiration of 60 days after the date on which it was issued (150 days if the taxpayer is outside the United States), a notice of deficiency shall constitute an assessment of the amount of tax and penalties specified therein, except only for such amounts as to which the taxpayer shall have filed a protest with the Department, as provided in Section 908.

(a) In general. Except as otherwise provided in this Act:

(1) A notice of deficiency shall be issued not later than 3 years after the date the return was filed, and

(2) No deficiency shall be assessed or collected with respect to the year for which the return was filed unless such notice is issued within such period.

(a-5) Notwithstanding any other provision of this Act to the contrary, for any taxable year included in a claim for credit or refund for which the statute of limitations for issuing a notice of deficiency under this Act will expire less than 6 months after the date a taxpayer files the claim for credit or refund, the statute of limitations is automatically extended for 6 months from the date it would have otherwise expired.

(b) Substantial omission of items.

(1) Omission of more than 25% of income. If the taxpayer omits from base income an amount properly includible therein which is in excess of 25% of the amount of base income stated in the return, a notice of deficiency may be issued not later than 6 years after the return was filed. For purposes of this paragraph, there shall not be taken into account any amount which is omitted in the return if such amount is disclosed in the return, or in a statement attached to the return, in a manner adequate to apprise the Department of the nature and the amount of such item.

(2) Reportable transactions. If a taxpayer fails to include on any return or statement for any taxable year any information with respect to a reportable transaction, as required under Section 501(b) of this Act, a notice of deficiency may be issued not later than 6 years after the return is filed with respect to the taxable year in which the taxpayer participated in the reportable transaction and said deficiency is limited to the non-disclosed item.

(3) Withholding. If an employer omits from a return required under Section 704A of this Act for any period beginning on or after January 1, 2013, an amount required to be withheld and to be reported on that return which is in excess of 25% of the total amount of withholding required to be reported on that return, a notice of deficiency may be issued not later than 6 years after the return was filed.

(c) No return or fraudulent return. If no return is filed or a false and fraudulent return is filed with intent to evade the tax imposed by this Act, a notice of deficiency may be issued at any time. For purposes of this subsection (c), any taxpayer who is required to join in the filing of a return filed under the provisions of subsection (e) of Section 502 of this Act for a taxable year ending on or after December 31, 2013 and who is not included on that return and does not file its own return for that taxable year shall be deemed to have failed to file a return; provided that the amount of any proposed assessment set forth in a notice of deficiency issued under this subsection (c) shall be limited to the amount of any increase in liability under this Act that should have reported on the return required under the provisions of subsection (e) of Section 502 of this Act for that taxable year resulting from proper inclusion of that taxpayer on that return.

(d) Failure to report federal change. If a taxpayer fails to notify the Department in any case where notification is required by Section 304(c) or 506(b), or fails to report a change or correction which is treated in the same manner as if it were a deficiency for federal income tax purposes, a notice of deficiency may be issued (i) at any time or (ii) on or after August 13, 1999, at any time for the taxable year for which the notification is required or for any taxable year to which the taxpayer may carry an Article 2 credit, or a Section 207 loss, earned, incurred, or used in the year for which the notification is required; provided, however, that the amount of any proposed assessment set forth in the notice shall be limited to the amount of any deficiency resulting under this Act from the recomputation of the taxpayer's net income, Article 2 credits, or Section 207 loss earned, incurred, or used in the taxable year for which the notification is required after giving effect to the item or items required to be reported.

(e) Report of federal change.

(1) Before August 13, 1999, in any case where notification of an alteration is given as required by Section 506(b), a notice of deficiency may be issued at any time within 2 years after the date such notification is given, provided, however, that the amount of any proposed assessment set forth in such notice shall be limited to the amount of any deficiency resulting under this Act from recomputation of the taxpayer's net income, net loss, or Article 2 credits for the taxable year after giving effect to the item or items reflected in the reported alteration.

(2) On and after August 13, 1999, in any case where notification of an alteration is given as required by Section 506(b), a notice of deficiency may be issued at any time within 2 years after the date such notification is given for the taxable year for which the notification is given or for any taxable year to which the taxpayer may carry an Article 2 credit, or a Section 207 loss, earned, incurred, or used in the year for which the notification is given, provided, however, that the amount of any proposed assessment set forth in such notice shall be limited to the amount of any deficiency resulting under this Act from recomputation of the taxpayer's net income, Article 2 credits, or Section 207 loss earned, incurred, or used in the taxable year for which the notification is given after giving effect to the item or items reflected in the reported alteration.

(f) Extension by agreement. Where, before the expiration of the time prescribed in this Section for the issuance of a notice of deficiency, both the Department and the taxpayer shall have consented in writing to its issuance after such time, such notice may be issued at any time prior to the expiration of the period agreed upon. In the case of a taxpayer who is a partnership, Subchapter S corporation, or trust and who enters into an agreement with the Department pursuant to this subsection on or after January 1, 2003, a notice of deficiency may be issued to the partners, shareholders, or beneficiaries of the taxpayer at any time prior to the expiration of the period agreed upon. Any proposed assessment set forth in the notice, however, shall be limited to the amount of any deficiency resulting under this Act from recomputation of items of income, deduction, credits, or other amounts of the taxpayer that are taken into account by the partner, shareholder, or beneficiary in computing its liability under this Act. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the period previously agreed upon.

(g) Erroneous refunds. In any case in which there has been an erroneous refund of tax payable under this Act, a notice of deficiency may be issued at any time within 2 years from the making of such refund, or within 5 years from the making of such refund if it appears that any part of the refund was induced by fraud or the misrepresentation of a material fact, provided, however, that the amount of any proposed assessment set forth in such notice shall be limited to the amount of such erroneous refund.

Beginning July 1, 1993, in any case in which there has been a refund of tax payable under this Act attributable to a net loss carryback as provided for in Section 207, and that refund is subsequently determined to be an erroneous refund due to a reduction in the amount of the net loss which was originally carried back, a notice of deficiency for the erroneous refund amount may be issued at any time during the same time period in which a notice of deficiency can be issued on the loss year creating the carryback amount and subsequent erroneous refund. The amount of any proposed assessment set forth in the notice shall be limited to the amount of such erroneous refund.

(h) Time return deemed filed. For purposes of this Section 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.

(i) Request for prompt determination of liability. For purposes of subsection (a)(1), in the case of a tax return required under this Act in respect of a decedent, or by his estate during the period of administration, or by a corporation, the period referred to in such Subsection shall be 18 months after a written request for prompt determination of liability is filed with the Department (at such time and in such form and manner as the Department shall by regulations prescribe) by the executor, administrator, or other fiduciary representing the estate of such decedent, or by such corporation, but not more than 3 years after the date the return was filed. This subsection shall not apply in the case of a corporation unless:

(1) (A) such written request notifies the Department that the corporation contemplates dissolution at or before the expiration of such 18-month period, (B) the dissolution is begun in good faith before the expiration of such 18-month period, and (C) the dissolution is completed;

(2) (A) such written request notifies the Department that a dissolution has in good faith been begun, and (B) the dissolution is completed; or

(3) a dissolution has been completed at the time such written request is made.

(j) Withholding tax. In the case of returns required under Article 7 of this Act (with respect to any amounts withheld as tax or any amounts required to have been withheld as tax) a notice of deficiency shall be issued not later than 3 years after the 15th day of the 4th month following the close of the calendar year in which such withholding was required.

(k) Penalties for failure to make information reports. A notice of deficiency for the penalties provided by Subsection 1405.1(c) of this Act may not be issued more than 3 years after the due date of the reports with respect to which the penalties are asserted.

(l) Penalty for failure to file withholding returns. A notice of deficiency for penalties provided by Section 1004 of this Act for the taxpayer's failure to file withholding returns may not be issued more than three years after the 15th day of the 4th month following the close of the calendar year in which the withholding giving rise to the taxpayer's obligation to file those returns occurred.

(m) Transferee liability. A notice of deficiency may be issued to a transferee relative to a liability asserted under Section 1405 during time periods defined as follows:

(1) Initial Transferee. In the case of the liability of an initial transferee, up to 2 years after the expiration of the period of limitation for assessment against the transferor, except that if a court proceeding for review of the assessment against the transferor has begun, then up to 2 years after the return of the certified copy of the judgment in the court proceeding.

(2) Transferee of Transferee. In the case of the liability of a transferee, up to 2 years after the expiration of the period of limitation for assessment against the preceding transferee, but not more than 3 years after the expiration of the period of limitation for assessment against the initial transferor; except that if, before the expiration of the period of limitation for the assessment of the liability of the transferee, a court proceeding for the collection of the tax or liability in respect thereof has been begun against the initial transferor or the last preceding transferee, as the case may be, then the period of limitation for assessment of the liability of the transferee shall expire 2 years after the return of the certified copy of the judgment in the court proceeding.

(n) Notice of decrease in net loss. On and after August 23, 2002, no notice of deficiency shall be issued as the result of a decrease determined by the Department in the net loss incurred by a taxpayer in any taxable year ending prior to December 31, 2002 under Section 207 of this Act unless the Department has notified the taxpayer of the proposed decrease within 3 years after the return reporting the loss was filed or within one year after an amended return reporting an increase in the loss was filed, provided that in the case of an amended return, a decrease proposed by the Department more than 3 years after the original return was filed may not exceed the increase claimed by the taxpayer on the original return.

Sec. 906. Further Notices of Deficiency Restricted.

If a protest has been filed with respect to a notice of deficiency issued by the Department with respect to a taxable year, and the decision of the Department on such protest has become final, the Department shall be barred from issuing a further or additional notice of deficiency for such taxable year, except in the case of fraud, mathematical error, a return that is not considered processable, as the term is defined in Section 3-2 of the Uniform Penalty and Interest Act, or as provided in section 905(d), (e), or (g).

Sec. 908. Procedure on protest.

(a) Time for protest. Within 60 days (150 days if the taxpayer is outside the United States) after the issuance of a notice of deficiency, the taxpayer may file (i) a protest against the proposed assessment with the Department or (ii) a petition with the Illinois Independent Tax Tribunal, as provided in this subsection (a). Prior to July 1, 2013, a written protest against the proposed assessment shall be filed with the Department in such form as the Department may by regulations prescribe, setting forth the grounds on which such protest is based. If such a protest is filed, the Department shall reconsider the proposed assessment and, if the taxpayer has so requested, shall grant the taxpayer or his authorized representative a hearing.

On and after July 1, 2013, all protests of a notice of deficiency that are subject to the jurisdiction of the Illinois Independent Tax Tribunal shall be filed by petition pursuant to the Illinois Independent Tax Tribunal Act of 2012.

With respect to protests filed with the Department prior to July 1, 2013 that are otherwise subject to the jurisdiction of the Illinois Independent Tax Tribunal, the taxpayer may elect to be subject to the provisions of the Illinois Independent Tax Tribunal Act of 2012 at any time on or after July 1, 2013, but not later than 30 days after the date on which the protest was filed. If made, the election shall be irrevocable.

(b) Notice of decision. With respect to protests filed with the Department that are not subject to the provisions of the Illinois Independent Tax Tribunal Act of 2012, as soon as practicable after such reconsideration and hearing, if any, the Department shall issue a notice of decision by mailing such notice by certified or registered mail. Such notice shall set forth briefly the Department's findings of fact and the basis of decision in each case decided in whole or in part adversely to the taxpayer.

(c) Request for rehearing. With respect to protests filed with the Department that are not subject to the provisions of the Illinois Independent Tax Tribunal Act of 2012, within 30 days after the mailing of a notice of decision, the taxpayer may file with a Department a written request for rehearing in such form as the Department may by regulations prescribe, setting forth the grounds on which rehearing is requested. In any such case, the Department shall, in its discretion, grant either a rehearing or Departmental review unless, within 10 days of receipt of such request, it shall issue a denial of such request by mailing such denial to the taxpayer by certified or registered mail. If rehearing or Departmental review is granted, as soon as practicable after such rehearing or Departmental review, the Department shall issue a notice of final decision as provided in subsection (b).

(d) Finality of decision. If the taxpayer fails to file a timely protest or petition under subsection (a) of this Section, then the Department's notice of deficiency shall become a final assessment at the end of the 60th day after the date of issuance of the notice of deficiency (or the 150th day if the taxpayer is outside the United States). If the taxpayer files a protest with the Department, and the taxpayer does not elect to be subject to the provisions of the Illinois Independent Tax Tribunal Act of 2012, then the action of the Department on the taxpayer's protest shall become final:

(1) 30 Days after issuance of a notice of decision as provided in subsection (b); or

(2) if a timely request for rehearing was made, upon the issuance of a denial of such request or the issuance of a notice of final decision as provided in subsection (c).

After the issuance of a final assessment, or a notice of deficiency which becomes final without the necessity of actually issuing a final assessment as provided in this Section, the Department, at any time before such assessment is reduced to judgment, may (subject to rules of the Department) grant a rehearing (or grant departmental review and hold an original hearing if no previous hearing in the matter has been held) upon the application of the person aggrieved. Pursuant to such hearing or rehearing, the Department shall issue a revised final assessment to such person or his legal representative for the amount found to be due as a result of such hearing or rehearing.

If the taxpayer files a petition with the Illinois Independent Tax Tribunal, or otherwise elects to be subject to the provisions of the Illinois Independent Tax Tribunal Act of 2012, then the Department's decision will become final as provided in that Act.

Sec. 909. Credits and Refunds.

(a) In general. In the case of any overpayment, the Department, within the applicable period of limitations for a claim for refund, may credit the amount of such overpayment, including any interest allowed thereon, against any liability in respect of the tax imposed by this Act, regardless of whether other collection remedies are closed to the Department on the part of the person who made the overpayment and shall refund any balance to such person or credit any balance to that person pursuant to an election under subsection (b) of this Section.

(b) Credits against estimated tax. The Department shall prescribe regulations providing for a taxpayer election on an original return, an amended return, or otherwise for the crediting against the estimated tax for any taxable year of the amount determined by the taxpayer or the Department to be an overpayment of the tax imposed by this Act for a preceding taxable year.

(c) Interest on overpayment. Interest shall be allowed and paid at the rate and in the manner prescribed in Section 3-2 of the Uniform Penalty and Interest Act upon any overpayment in respect of the tax imposed by this Act. For purposes of this subsection, no amount of tax, for any taxable year, shall be treated as having been paid before the date on which the tax return for such year was due under Section 505, without regard to any extension of the time for filing such return.

(d) Refund claim. Every claim for refund shall be filed with the Department in writing in such form as the Department may by regulations prescribe, and shall state the specific grounds upon which it is founded.

(e) Notice of denial. As soon as practicable after a claim for refund is filed, the Department shall examine it and either issue a notice of refund, abatement or credit to the claimant or issue a notice of denial. If the Department has failed to approve or deny the claim before the expiration of 6 months from the date the claim was filed, the claimant may nevertheless thereafter file with the Department a written protest in such form as the Department may by regulation prescribe, provided that, on or after July 1, 2013, protests concerning matters that are subject to the jurisdiction of the Illinois Independent Tax Tribunal shall be filed with the Illinois Independent Tax Tribunal and not with the Department. If the protest is subject to the jurisdiction of the Department, the Department shall consider the claim and, if the taxpayer has so requested, shall grant the taxpayer or the taxpayer's authorized representative a hearing within 6 months after the date such request is filed.

On and after July 1, 2013, if the protest would otherwise be subject to the jurisdiction of the Illinois Independent Tax Tribunal, the claimant may elect to treat the Department's non-action as a denial of the claim by filing a petition to review the Department's administrative decision with the Illinois Independent Tax Tribunal, as provided by Section 910.

(f) Effect of denial. A denial of a claim for refund becomes final 60 days after the date of issuance of the notice of such denial except for such amounts denied as to which the claimant has filed a protest with the Department or a petition with the Illinois Independent Tax Tribunal, as provided by Section 910.

(g) An overpayment of tax shown on the face of an unsigned return shall be considered forfeited to the State if after notice and demand for signature by the Department the taxpayer fails to provide a signature and 3 years have passed from the date the return was filed. An overpayment of tax refunded to a taxpayer whose return was filed electronically shall be considered an erroneous refund under Section 912 of this Act if, after proper notice and demand by the Department, the taxpayer fails to provide a required signature document. A notice and demand for signature in the case of a return reflecting an overpayment may be made by first class mail. This subsection (g) shall apply to all returns filed pursuant to this Act since 1969.

(h) This amendatory Act of 1983 applies to returns and claims for refunds filed with the Department on and after July 1, 1983.

Such notice shall set forth briefly the Department's findings of fact and the basis of decision in each case decided in whole or in part adversely to the claimant.

(c) Request for rehearing. Within 30 days after the mailing of a notice of decision as provided in subsection (b), the claimant may file with the Department a written request for rehearing in such form as the Department may by regulations prescribe, setting forth the grounds on which rehearing is requested. In any such case, the Department shall, in its discretion, grant either a rehearing or Departmental review unless, within 10 days of receipt of such request, it shall issue a denial of such request by mailing such denial to the claimant by certified or registered mail. If rehearing or Departmental review is granted, as soon as practicable after such rehearing or Departmental review, the Department shall issue a notice of final decision as provided in subsection (b).

(d) Finality of decision. If the taxpayer fails to file a timely protest or petition under subsection (a) of this Section, then the Department's notice of deficiency shall become a final assessment at the end of the 60th day after the date of issuance of the notice of deficiency. If the protest is subject to the jurisdiction of the Department, and the taxpayer does not elect to be subject to the provisions of the Illinois Independent Tax Tribunal Act of 2012, then the action of the Department on the claimant's protest shall become final:

(1) 30 days after issuance of a notice of decision as provided in subsection (b); or

(2) If a timely request for rehearing was made, upon the issuance of a denial of such request or the issuance of a notice of final decision as provided in subsection (c).

If the taxpayer files a petition with the Illinois Independent Tax Tribunal, or otherwise elects to be subject to the provisions of the Illinois Independent Tax Tribunal Act of 2012, then the Department's decision will become final as provided in that Act.

Sec. 911. Limitations on claims for refund.

(a) In general. Except as otherwise provided in this Act:

(1) A claim for refund shall be filed not later than 3 years after the date the return was filed (in the case of returns required under Article 7 of this Act respecting any amounts withheld as tax, not later than 3 years after the 15th day of the 4th month following the close of the calendar year in which such withholding was made), or one year after the date the tax was paid, whichever is the later; and

(2) No credit or refund shall be allowed or made with respect to the year for which the claim was filed unless such claim is filed within such period.

(b) Federal changes.

(1) In general. In any case where notification of an alteration is required by Section 506(b), a claim for refund may be filed within 2 years after the date on which such notification was due (regardless of whether such notice was given), but the amount recoverable pursuant to a claim filed under this Section shall be limited to the amount of any overpayment resulting under this Act from recomputation of the taxpayer's net income, net loss, or Article 2 credits for the taxable year after giving effect to the item or items reflected in the alteration required to be reported.

(2) Tentative carryback adjustments paid before January 1, 1974. If, as the result of the payment before January 1, 1974 of a federal tentative carryback adjustment, a notification of an alteration is required under Section 506(b), a claim for refund may be filed at any time before January 1, 1976, but the amount recoverable pursuant to a claim filed under this Section shall be limited to the amount of any overpayment resulting under this Act from recomputation of the taxpayer's base income for the taxable year after giving effect to the federal alteration resulting from the tentative carryback adjustment irrespective of any limitation imposed in paragraph (1) of this subsection.

(c) Extension by agreement. Where, before the expiration of the time prescribed in this section for the filing of a claim for refund, both the Department and the claimant shall have consented in writing to its filing after such time, such claim may be filed at any time prior to the expiration of the period agreed upon. The period so agreed upon may be extended by subsequent agreements in writing made before the expiration of the period previously agreed upon. In the case of a taxpayer who is a partnership, Subchapter S corporation, or trust and who enters into an agreement with the Department pursuant to this subsection on or after January 1, 2003, a claim for refund may be filed by the partners, shareholders, or beneficiaries of the taxpayer at any time prior to the expiration of the period agreed upon. Any refund allowed pursuant to the claim, however, shall be limited to the amount of any overpayment of tax due under this Act that results from recomputation of items of income, deduction, credits, or other amounts of the taxpayer that are taken into account by the partner, shareholder, or beneficiary in computing its liability under this Act.

(d) Limit on amount of credit or refund.

(1) Limit where claim filed within 3-year period. If the claim was filed by the claimant during the 3-year period prescribed in subsection (a), the amount of the credit or refund shall not exceed the portion of the tax paid within the period, immediately preceding the filing of the claim, equal to 3 years plus the period of any extension of time for filing the return.

(2) Limit where claim not filed within 3-year period. If the claim was not filed within such 3-year period, the amount of the credit or refund shall not exceed the portion of the tax paid during the one year immediately preceding the filing of the claim.

(e) Time return deemed filed. For purposes of this section a tax return filed before the last day prescribed by law for the filing of such return (including any extensions thereof) shall be deemed to have been filed on such last day.

(f) No claim for refund or credit based on the taxpayer's taking a credit for estimated tax payments as provided by Section 601(b)(2) or for any amount paid by a taxpayer pursuant to Section 602(a) or for any amount of credit for tax withheld pursuant to Article 7 may be filed unless a return was filed for the tax year not more than 3 years after the due date, as provided by Section 505, of the return which was required to be filed relative to the taxable year for which the payments were made or for which the tax was withheld. The changes in this subsection (f) made by this amendatory Act of 1987 shall apply to all taxable years ending on or after December 31, 1969.

(g) Special Period of Limitation with Respect to Net Loss Carrybacks. If the claim for refund relates to an overpayment attributable to a net loss carryback as provided by Section 207, in lieu of the 3 year period of limitation prescribed in subsection (a), the period shall be that period which ends 3 years after the time prescribed by law for filing the return (including extensions thereof) for the taxable year of the net loss which results in such carryback (or, on and after August 13, 1999, with respect to a change in the carryover of an Article 2 credit to a taxable year resulting from the carryback of a Section 207 loss incurred in a taxable year beginning on or after January 1, 2000, the period shall be that period that ends 3 years after the time prescribed by law for filing the return (including extensions of that time) for that subsequent taxable year), or the period prescribed in subsection (c) in respect of such taxable year, whichever expires later. In the case of such a claim, the amount of the refund may exceed the portion of the tax paid within the period provided in subsection (d) to the extent of the amount of the overpayment attributable to such carryback. On and after August 13, 1999, if the claim for refund relates to an overpayment attributable to the carryover of an Article 2 credit, or of a Section 207 loss, earned, incurred (in a taxable year beginning on or after January 1, 2000), or used in a year for which a notification of a change affecting federal taxable income must be filed under subsection (b) of Section 506, the claim may be filed within the period prescribed in paragraph (1) of subsection (b) in respect of the year for which the notification is required. In the case of such a claim, the amount of the refund may exceed the portion of the tax paid within the period provided in subsection (d) to the extent of the amount of the overpayment attributable to the recomputation of the taxpayer's Article 2 credits, or Section 207 loss, earned, incurred, or used in the taxable year for which the notification is given.

(h) Claim for refund based on net loss. On and after August 23, 2002, no claim for refund shall be allowed to the extent the refund is the result of an amount of net loss incurred in any taxable year ending prior to December 31, 2002 under Section 207 of this Act that was not reported to the Department within 3 years of the due date (including extensions) of the return for the loss year on either the original return filed by the taxpayer or on amended return or to the extent that the refund is the result of an amount of net loss incurred in any taxable year under Section 207 for which no return was filed within 3 years of the due date (including extensions) of the return for the loss year.

(i) Periods of limitation suspended while taxpayer is unable to manage financial affairs due to disability. In the case of an individual, the running of the periods specified in this Section shall be suspended during any period when that individual is financially disabled.

For purposes of this subsection (i), an individual is financially disabled if that individual is unable to manage his or her financial affairs by reason of a medically determinable physical or mental impairment of the individual that can be expected to result in death, or which has lasted or can be expected to last for a continuous period of not less than 12 months.

An individual shall not be treated as financially disabled during any period when that individual's spouse or any other person is authorized to act on behalf of that individual with respect to financial matters.
