(55 ILCS 5/5-1035.1) (from Ch. 34, par. 5-1035.1)
    Sec. 5-1035.1. County Motor Fuel Tax Law. The county board of the counties of DuPage, Kane and McHenry may, by an ordinance or resolution adopted by an affirmative vote of a majority of the members elected or appointed to the county board, impose a tax upon all persons engaged in the county in the business of selling motor fuel, as now or hereafter defined in the Motor Fuel Tax Law, at retail for the operation of motor vehicles upon public highways or for the operation of recreational watercraft upon waterways. Kane County may exempt diesel fuel from the tax imposed pursuant to this Section. The tax may be imposed, in half-cent increments, at a rate not exceeding 4 cents per gallon of motor fuel sold at retail within the county for the purpose of use or consumption and not for the purpose of resale. The proceeds from the tax shall be used by the county solely for the purpose of operating, constructing and improving public highways and waterways, and acquiring real property and right-of-ways for public highways and waterways within the county imposing the tax.
    A tax imposed pursuant to this Section, and all civil penalties that may be assessed as an incident thereof, shall be administered, collected and enforced by the Illinois Department of Revenue in the same manner as the tax imposed under the Retailers' Occupation Tax Act, as now or hereafter amended, insofar as may be practicable; except that in the event of a conflict with the provisions of this Section, this Section shall control. The Department of Revenue shall have full power: to administer and enforce this Section; to collect all taxes and penalties due hereunder; to dispose of taxes and penalties so collected in the manner hereinafter provided; and to determine all rights to credit memoranda arising on account of the erroneous payment of tax or penalty hereunder.
    Whenever the Department determines that a refund shall be made under this Section to a claimant instead of issuing a credit memorandum, the Department shall notify the State Comptroller, who shall cause the order to be drawn for the amount specified, and to the person named, in the notification from the Department. The refund shall be paid by the State Treasurer out of the County Option Motor Fuel Tax Fund.
    The Department shall forthwith pay over to the State Treasurer, ex-officio, as trustee, all taxes and penalties collected hereunder, which shall be deposited into the County Option Motor Fuel Tax Fund, a special fund in the State Treasury which is hereby created. On or before the 25th day of each calendar month, the Department shall prepare and certify to the State Comptroller the disbursement of stated sums of money to named counties for which taxpayers have paid taxes or penalties hereunder to the Department during the second preceding calendar month. The amount to be paid to each county shall be the amount (not including credit memoranda) collected hereunder from retailers within the county during the second preceding calendar month by the Department, but not including an amount equal to the amount of refunds made during the second preceding calendar month by the Department on behalf of the county; less 2% of the balance, which sum shall be retained by the State Treasurer to cover the costs incurred by the Department in administering and enforcing the provisions of this Section. The Department, at the time of each monthly disbursement to the counties, shall prepare and certify to the Comptroller the amount so retained by the State Treasurer, which shall be transferred into the Tax Compliance and Administration Fund.
    A county may direct, by ordinance, that all or a portion of the taxes and penalties collected under the County Option Motor Fuel Tax shall be deposited into the Transportation Development Partnership Trust Fund.
    Nothing in this Section shall be construed to authorize a county to impose a tax upon the privilege of engaging in any business which under the Constitution of the United States may not be made the subject of taxation by this State.
    An ordinance or resolution imposing a tax hereunder or effecting a change in the rate thereof shall be effective on the first day of the second calendar month next following the month in which the ordinance or resolution is adopted and a certified copy thereof is filed with the Department of Revenue, whereupon the Department of Revenue shall proceed to administer and enforce this Section on behalf of the county as of the effective date of the ordinance or resolution. Upon a change in rate of a tax levied hereunder, or upon the discontinuance of the tax, the county board of the county shall, on or not later than 5 days after the effective date of the ordinance or resolution discontinuing the tax or effecting a change in rate, transmit to the Department of Revenue a certified copy of the ordinance or resolution effecting the change or discontinuance.
    This Section shall be known and may be cited as the County Motor Fuel Tax Law.
