(35 ILCS 405/8) (from Ch. 120, par. 405A-8)

Sec. 8. Penalties for failure to file tax return or to pay tax.

(a) Failure to file return. In case of failure to file any return required under this Act with the Attorney General by the due date, unless it is shown that the failure to file is due to a reasonable cause, there shall be added to the amount required to be shown as tax on the return 5% of the amount of that tax (or 5% of the additional tax due in the case of a supplemental return) if the failure is for not more than one month from the due date, with an additional 5% for each additional month or fraction of a month thereafter during which the failure to file continues, not exceeding in the aggregate 25% of the tax or, in the case of a supplemental return, 25% of the additional tax.

(b) Failure to pay tax. In the case of failure to pay the amount of tax shown due on any return required under this Act on or before the due date for payment of that tax, unless it is shown that the failure to pay is due to reasonable cause, there shall be added to the unpaid amount of the tax 0.5% of that unpaid amount if the failure is for not more than one month from the due date, with an additional 0.5% for each additional month or fraction of a month thereafter during which the failure to pay continues, not exceeding in the aggregate 25% of the unpaid amount.

(c) Extensions of Time.

(1) Internal Revenue Service Extensions. If the date for filing the federal return or the date for payment of the federal transfer tax is extended by the Internal Revenue Service, the filing of the return and payment of the tax imposed by this Act shall be due on the respective date specified by the Internal Revenue Service in granting a request for extension. If the request for extension is granted by the Internal Revenue Service, the person required to file the Illinois transfer tax return shall furnish the Attorney General with a copy of the request for extension showing approval of the extension by the Internal Revenue Service. If a request for extension of time to file the federal return is denied by the Internal Revenue Service, no penalty shall be due under this Act if the return required by this Act is filed within the time specified by the Internal Revenue Service for filing the federal return. If a request for extension of time to pay the federal transfer tax is denied by the Internal Revenue Service, no penalty shall be due under this Act if the tax is paid within the time specified by the Internal Revenue Service for paying the federal transfer tax.

(2) Attorney General Extensions. The person or persons required to file the Illinois transfer tax return and to pay the Illinois transfer tax may apply to the Attorney General for an extension of time to file the Illinois transfer tax return or to pay the Illinois transfer tax. The application must establish reasonable cause why it is impossible or impractical to file a reasonably complete return or to pay the full amount of tax due by the due date. The Attorney General may for reasonable cause extend the time for filing the return or paying the tax for a reasonable period from the date fixed for filing the return or paying the tax.

(d) Waiver of Penalties.

(1) Internal Revenue Service Waiver. If the Internal Revenue Service waives the penalty provided in the Internal Revenue Code for failure to timely file the federal return or the penalty for failure to timely pay the federal transfer tax liability, such waiver or waivers shall be deemed to constitute reasonable cause for purposes of this Section.

(2) Attorney General Waiver. The Attorney General may waive the penalty or penalties for failure to file or pay for reasonable cause, notwithstanding the failure of the Internal Revenue Service to waive the penalty or penalties for failure to timely file the federal transfer tax return or to pay the federal transfer tax.

(35 ILCS 405/10) (from Ch. 120, par. 405A-10)

Sec. 10. Liens and Personal Liability.

(a) Lien for Illinois transfer tax. Unless the Illinois transfer tax is sooner paid in full, the Illinois transfer tax shall be a lien in favor of this State upon the transferred property having a tax situs within this State for 10 years from the date of the taxable transfer, or, in the case of Illinois transfer tax subject to deferral or payable in installments, the later of 10 years from the date of the taxable transfer or one year after the last deferred or installment payment may become due. The lien imposed by this Section on the transferred property shall not be valid as against any purchaser, mortgagee, pledgee, or other holder of a security interest for a full and adequate consideration in money or money's worth; provided, however, that any property, consideration or proceeds received as a result of any sale, mortgage, pledge or granting of a security interest shall remain subject to the lien imposed by this Section. In addition, the lien imposed by this Section on the transferred property shall be subject to the exceptions set forth in Section 6324(c)(i) of the Internal Revenue Code as if the lien were a lien imposed by that Section. In no event shall the issuance by the Attorney General of a release of the lien imposed by this subsection be required with respect to the sale, mortgage, pledge, granting of a security interest in, transfer or distribution of transferred property.

(b) Special lien for property valued under Section 2032A of the Internal Revenue Code. In the event the Illinois estate tax is reduced as a result of an election under Section 2032A of the Internal Revenue Code, then an amount equal to the additional Illinois estate tax that would be due in the absence of such an election shall be a lien in favor of this State on the transferred property that has a tax situs in this State and is subject to such election. The lien imposed by this subsection shall arise at the time an election is filed under Section 2032A of the Internal Revenue Code and shall continue with respect to such transferred property:

(1) until the liability for the Illinois estate tax with respect to such transferred property has been satisfied or has become unenforceable by reason of lapse of time or otherwise; or

(2) until it is established to the satisfaction of the Attorney General that no further tax liability may arise under this Act with respect to such transferred property.

The lien imposed by this subsection shall not be valid as against any purchaser, mortgagee, pledgee, other holder of a security interest, mechanic's lien, or judgment lien creditor until notice of such lien has been filed as provided by the laws of this State. In regulations prescribed in accordance with Section 16 of this Act, the Attorney General may require that the qualified heir file such notice of lien. Even though notice of said lien has been filed as provided in the preceding sentence, such lien shall be subject to the rules set forth in paragraph (3) of Section 6324A(d) of the Internal Revenue Code as if the lien were a lien imposed by that Section.

(c) Personal liability. If the Illinois transfer tax is not paid when due, then the person required to file the federal return and the transferee of any transferred property having a tax situs within this State shall be personally liable for the Illinois transfer tax, to the extent of such transferred property originally received, controlled or transferred to that person or transferee, less the amount of any expenses or charges against the transferred property, related to the taxable transfer, which have a higher priority of payment under applicable law than the Illinois transfer tax.

(d) Collection. The Attorney General shall have the right to sue for collection of the Illinois transfer tax for 3 years after the date of the actual filing of the related Illinois transfer tax return with the Attorney General, or, if later, the last date upon which application for refund of the Illinois transfer tax could be filed with the State Treasurer.

(e) Waiver of lien and personal liability. If the Attorney General is satisfied that no liability for Illinois transfer tax exists or that the Illinois transfer tax has been fully discharged or provided for, the Attorney General shall issue a certificate releasing all of the transferred property having a tax situs within the State of Illinois from the lien imposed by this Section. Issuance of such certificate shall discharge the person required to file the Illinois return and any transferee from personal liability for the Illinois transfer tax.

Sec. 11. Reimbursement. If the person who pays the Illinois transfer tax arising from a taxable transfer is entitled under the Internal Revenue Code or any other state or federal statute or rule of law to reimbursement of a portion of the federal transfer tax from any other person who has received transferred property, then, unless the governing document directs otherwise, the person who paid the Illinois transfer tax shall also be entitled to reimbursement from that other person of a portion of the Illinois transfer tax. The amount of reimbursement shall be determined by multiplying the total Illinois transfer tax by a fraction, the numerator of which shall be the gross value of the transferred property received by that other person and having a tax situs in this State which gives rise to a right of reimbursement of the federal transfer tax, and the denominator of which shall be the gross value of all transferred property having a tax situs in this State.

A parent, without being appointed guardian of the person or guardian of the estate, or a guardian of the estate, or, if no guardian of the estate has been appointed, a guardian of the person, of any minor or person with a disability whose interest is not adverse to the minor or person with a disability, may make any election and sign, without court approval, any agreement on behalf of the minor or person with a disability under (i) Section 2032A of the Internal Revenue Code for the valuation of property under that Section or (ii) Section 2057 of the Internal Revenue Code relating to deduction of the value of certain property under that Section. Any election so made, and any agreement so signed, shall have the same legal force and effect as if the election had been made and the agreement had been signed by the minor or person with a disability and the minor or person with a disability had been legally competent.

This amendatory Act of the 91st General Assembly applies to elections and agreements made on or after January 1, 1998 in reliance on or pursuant to Section 2057 of the Internal Revenue Code, and those elections and agreements made before the effective date of this amendatory Act are hereby validated.

Sec. 13. Collection by county treasurers; tax collection distribution fund.

(a) Collection by county treasurers. Each county treasurer shall transmit to the State Treasurer all taxes, interest or penalties paid to the county treasurer under this Act and in the county treasurer's possession as of the last day of the previous month, together with a report under oath identifying the taxpayer for or by whom an amount was paid. Those amounts and the report shall be transmitted to and received by the State Treasurer by the 10th day of each month. At the same time, a copy of the report shall be furnished to the Attorney General. The report shall be in a form and contain the particulars as the State Treasurer may prescribe. The State Treasurer shall give the county treasurer a receipt for the amount transmitted to the State Treasurer. Except as provided in subsection (a-5) of this Section, if any county treasurer fails to pay to the State Treasurer all amounts that may be due and payable under this Act as required by this Section, the county treasurer shall pay to the State Treasurer, as a penalty, a sum of money equal to the interest on the amounts not paid at the rate of 1% per month from the time those amounts are due by the county treasurer until those amounts are paid. The sureties upon the official bond of the county treasurer shall be security for the payment of the penalty. The penalty under this Section may be recovered in a civil action against the county treasurer and his or her sureties, in the name of the People of the State of Illinois, in the circuit court within the county wherein the county treasurer is resident; and the penalty, when recovered, shall be paid into the State treasury. The civil action to recover the penalty shall be brought by the State treasurer within 10 days after the failure of the county treasurer to pay to the State Treasurer any amounts collected by the county treasurer within the time required by this Act. Failure to bring the action within that time shall not prevent the bringing of the action thereafter. It is the duty of the State Treasurer to make necessary and proper investigation to determine what amounts should be paid under this Act.

(a-5) The State Treasurer may waive penalties imposed by subsection (a) of this Section on a case-by-case basis if the State Treasurer finds that imposing penalties would be unreasonable or unnecessarily burdensome because the delay in payment was due to an incident caused by the operation of an extraordinary force, including, but not limited to, the occurrence of a natural disaster, that cannot be foreseen, that cannot be avoided by the exercise of due care, and for which no person can be held liable.

(b) (Blank).

(c) On and after July 1, 2012, 94% of the amounts collected from the taxes, interest, and penalties collected under this Act shall be deposited into the General Revenue Fund and 6% of those amounts shall be deposited into the Estate Tax Refund Fund, a special fund created in the State treasury.

Moneys in the Estate Tax Refund Fund shall be expended exclusively for the purpose of paying refunds resulting from overpayment of tax liability under this Act, except that, whenever the State Treasurer determines that any such moneys in the Fund exceed the amount required for the purpose of paying refunds resulting from overpayment of tax liability under this Act, the State Treasurer may transfer any such excess amounts from the Estate Tax Refund Fund to the General Revenue Fund.

The Treasurer shall order payment of refunds resulting from overpayment of tax liability under this Act from the Estate Tax Refund Fund only to the extent that amounts have been deposited and retained in the Fund.

Public Act 97-732 shall constitute an irrevocable and continuing appropriation from the Estate Tax Refund Fund for the purpose of paying refunds upon the order of the Treasurer in accordance with the provisions of this Act and for the purpose of paying refunds under this Act.

It is the duty of the Attorney General to exercise general supervision over the assessment and collection of the tax provided in this Act, and in the discharge of that duty, the Attorney General may prescribe rules and regulations as are deemed necessary and may institute and prosecute suits and proceedings as may be necessary and proper, appearing therein for that purpose; and it shall be the duty of the several State's Attorneys to render assistance when requested by the Attorney General to do so. The Attorney General shall determine and assess the tax as provided for in this Act.

(b) Disclosure of federal return information. When receipt of estate tax information from the Internal Revenue Service under the Agreement on Coordination of Tax Administration between the Internal Revenue Service and the Attorney General discloses possible Illinois estate tax liability, any person possessing federal estate tax information shall be required to submit such information to the Attorney General upon request to enable the Attorney General to audit the return or Internal Revenue Service audit adjustments and to determine whether any tax, penalty, or interest is due the State of Illinois where such return information has not been filed with the Attorney General. A claim of confidentiality under Section 48.1 of the Illinois Banking Act shall not prohibit or preclude the dissemination of tax information required under this Section and shall not constitute grounds for failing or refusing to surrender such tax information to the Attorney General in the administration and enforcement of this Act. Any tax information submitted in compliance with this Section shall be treated and afforded with the same confidentiality as a return filed under the Act.
