Sec. 1-45. Jurisdiction of the Tax Tribunal.

(a) Except as provided by the Constitution of the United States, the Constitution of the State of Illinois, or any statutes of this State, including, but not limited to, the State Officers and Employees Money Disposition Act, the Tax Tribunal shall have original jurisdiction over all determinations of the Department reflected on a Notice of Deficiency, Notice of Tax Liability, Notice of Claim Denial, or Notice of Penalty Liability issued under the Illinois Income Tax Act, the Use Tax Act, the Service Use Tax Act, the Service Occupation Tax Act, the Retailers' Occupation Tax Act, the Cigarette Tax Act, the Cigarette Use Tax Act, the Tobacco Products Tax Act of 1995, the Hotel Operators' Occupation Tax Act, the Motor Fuel Tax Law, the Automobile Renting Occupation and Use Tax Act, the Coin-Operated Amusement Device and Redemption Machine Tax Act, the Gas Revenue Tax Act, the Water Company Invested Capital Tax Act, the Telecommunications Excise Tax Act, the Telecommunications Infrastructure Maintenance Fee Act, the Public Utilities Revenue Act, the Electricity Excise Tax Law, the Aircraft Use Tax Law, the Watercraft Use Tax Law, the Gas Use Tax Law, or the Uniform Penalty and Interest Act. Jurisdiction of the Tax Tribunal is limited to Notices of Tax Liability, Notices of Deficiency, Notices of Claim Denial, and Notices of Penalty Liability where the amount at issue in a notice, or the aggregate amount at issue in multiple notices issued for the same tax year or audit period, exceeds $15,000, exclusive of penalties and interest. In notices solely asserting either an interest or penalty assessment, or both, the Tax Tribunal shall have jurisdiction over cases where the combined total of all penalties or interest assessed exceeds $15,000.

(b) Except as otherwise permitted by this Act and by the Constitution of the State of Illinois or otherwise by State law, including, but not limited to, the State Officers and Employees Money Disposition Act, no person shall contest any matter within the jurisdiction of the Tax Tribunal in any action, suit, or proceeding in the circuit court or any other court of the State. If a person attempts to do so, then such action, suit, or proceeding shall be dismissed without prejudice. The improper commencement of any action, suit, or proceeding does not extend the time period for commencing a proceeding in the Tax Tribunal.

(c) The Tax Tribunal may require the taxpayer to post a bond equal to 25% of the liability at issue (1) upon motion of the Department and a showing that (A) the taxpayer's action is frivolous or legally insufficient or (B) the taxpayer is acting primarily for the purpose of delaying the collection of tax or prejudicing the ability ultimately to collect the tax, or (2) if, at any time during the proceedings, it is determined by the Tax Tribunal that the taxpayer is not pursuing the resolution of the case with due diligence. If the Tax Tribunal finds in a particular case that the taxpayer cannot procure and furnish a satisfactory surety or sureties for the kind of bond required herein, the Tax Tribunal may relieve the taxpayer of the obligation of filing such bond, if, upon the timely application for a lien in lieu thereof and accompanying proof therein submitted, the Tax Tribunal is satisfied that any such lien imposed would operate to secure the assessment in the manner and to the degree as would a bond. The Tax Tribunal shall adopt rules for the procedures to be used in securing a bond or lien under this Section.

(d) If, with or after the filing of a timely petition, the taxpayer pays all or part of the tax or other amount in issue before the Tax Tribunal has rendered a decision, the Tax Tribunal shall treat the taxpayer's petition as a protest of a denial of claim for refund of the amount so paid upon a written motion filed by the taxpayer.

(e) The Tax Tribunal shall not have jurisdiction to review:

(1) any assessment made under the Property Tax Code;

(2) any decisions relating to the issuance or denial of an exemption ruling for any entity claiming exemption from any tax imposed under the Property Tax Code or any State tax administered by the Department;

(3) a notice of proposed tax liability, notice of proposed deficiency, or any other notice of proposed assessment or notice of intent to take some action;

(4) any action or determination of the Department regarding tax liabilities that have become finalized by law, including but not limited to the issuance of liens, levies, and revocations, suspensions, or denials of licenses or certificates of registration or any other collection activities;

(5) any proceedings of the Department's informal administrative appeals function; and

(6) any challenge to an administrative subpoena issued by the Department.

(f) The Tax Tribunal shall decide questions regarding the constitutionality of statutes and rules adopted by the Department as applied to the taxpayer, but shall not have the power to declare a statute or rule unconstitutional or otherwise invalid on its face. A taxpayer challenging the constitutionality of a statute or rule on its face may present such challenge to the Tax Tribunal for the sole purpose of making a record for review by the Illinois Appellate Court. Failure to raise a constitutional issue regarding the application of a statute or regulations to the taxpayer shall not preclude the taxpayer or the Department from raising those issues at the appellate court level.
