Beginning July 1, 1994, and continuing through June 30, 1995, the Treasurer shall transfer each month from the General Revenue Fund to the Local Government Distributive Fund an amount equal to 1/11 of the net revenue realized from the tax imposed by subsections (a) and (b) of Section 201 of this Act during the preceding month.

For all other fiscal years, the Annual Percentage shall be calculated as a fraction, the numerator of which shall be the amount of refunds approved for payment by the Department during the preceding fiscal year as a result of overpayment of tax liability under subsections (a) and (b)(1), (2), and (3) of Section 201 of this Act plus the amount of such refunds remaining approved but unpaid at the end of the preceding fiscal year, minus the amounts transferred into the Income Tax Refund Fund from the Tobacco Settlement Recovery Fund, and the denominator of which shall be the amounts which will be collected pursuant to subsections (a) and (b)(1), (2), and (3) of Section 201 of this Act during the preceding fiscal year; except that in State fiscal year 2002, the Annual Percentage shall in no event exceed 7.6%. The Director of Revenue shall certify the Annual Percentage to the Comptroller on the last business day of the fiscal year immediately preceding the fiscal year for which it is to be effective.
        (2) Beginning on January 1, 1989 and thereafter, the
    Department shall deposit a percentage of the amounts collected pursuant to subsections (a) and (b)(6), (7), and (8), (c) and (d) of Section 201 of this Act into a fund in the State treasury known as the Income Tax Refund Fund.

For fiscal year 2007, the Annual Percentage shall be 17.5%. For fiscal year 2008, the Annual Percentage shall be 15.5%. For fiscal year 2009, the Annual Percentage shall be 17.5%. For fiscal year 2010, the Annual Percentage shall be 17.5%. For fiscal year 2011, the Annual Percentage shall be 17.5%.

        (3) As soon as possible after the end of each fiscal
    year, the Director shall order transferred and the State Treasurer and State Comptroller shall transfer from the Income Tax Refund Fund to the Personal Property Tax Replacement Fund an amount, certified by the Director to the Comptroller, equal to the excess of the amount collected pursuant to subsections (c) and (d) of Section 201 of this Act deposited into the Income Tax Refund Fund during the fiscal year over the amount of refunds resulting from overpayment of tax liability under subsections (c) and (d) of Section 201 of this Act paid from the Income Tax Refund Fund during the fiscal year.
        (4) As soon as possible after the end of each fiscal

    (35 ILCS 5/902)(from Ch. 120, par. 9‑902)
    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 after the sale or transfer, file a notice of sale or transfer of business assets with the Chicago office of 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.

    (35 ILCS 5/904) (from Ch. 120, par. 9‑904)
    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.

    (35 ILCS 5/905)(from Ch. 120, par. 9‑905)
    Sec. 905. Limitations on Notices of Deficiency.
    (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.
    (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.
    (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.
    (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 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 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
