(30 ILCS 105/6z-20) (from Ch. 127, par. 142z-20)
    Sec. 6z-20. County and Mass Transit District Fund. Of the money received from the 6.25% general rate (and, beginning July 1, 2000 and through December 31, 2000, the 1.25% rate on motor fuel and gasohol, and beginning on August 6, 2010 through August 15, 2010, the 1.25% rate on sales tax holiday items) on sales subject to taxation under the Retailers' Occupation Tax Act and Service Occupation Tax Act and paid into the County and Mass Transit District Fund, distribution to the Regional Transportation Authority tax fund, created pursuant to Section 4.03 of the Regional Transportation Authority Act, for deposit therein shall be made based upon the retail sales occurring in a county having more than 3,000,000 inhabitants. The remainder shall be distributed to each county having 3,000,000 or fewer inhabitants based upon the retail sales occurring in each such county.
    For the purpose of determining allocation to the local government unit, a retail sale by a producer of coal or other mineral mined in Illinois is a sale at retail at the place where the coal or other mineral mined in Illinois is extracted from the earth. This paragraph does not apply to coal or other mineral when it is delivered or shipped by the seller to the purchaser at a point outside Illinois so that the sale is exempt under the United States Constitution as a sale in interstate or foreign commerce.
    Of the money received from the 6.25% general use tax rate on tangible personal property which is purchased outside Illinois at retail from a retailer and which is titled or registered by any agency of this State's government and paid into the County and Mass Transit District Fund, the amount for which Illinois addresses for titling or registration purposes are given as being in each county having more than 3,000,000 inhabitants shall be distributed into the Regional Transportation Authority tax fund, created pursuant to Section 4.03 of the Regional Transportation Authority Act. The remainder of the money paid from such sales shall be distributed to each county based on sales for which Illinois addresses for titling or registration purposes are given as being located in the county. Any money paid into the Regional Transportation Authority Occupation and Use Tax Replacement Fund from the County and Mass Transit District Fund prior to January 14, 1991, which has not been paid to the Authority prior to that date, shall be transferred to the Regional Transportation Authority tax fund.
    Whenever the Department determines that a refund of money paid into the County and Mass Transit District Fund should be made 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 such notification from the Department. Such refund shall be paid by the State Treasurer out of the County and Mass Transit District Fund.
    As soon as possible after the first day of each month, beginning January 1, 2011, upon certification of the Department of Revenue, the Comptroller shall order transferred, and the Treasurer shall transfer, to the STAR Bonds Revenue Fund the local sales tax increment, as defined in the Innovation Development and Economy Act, collected during the second preceding calendar month for sales within a STAR bond district and deposited into the County and Mass Transit District Fund, less 3% of that amount, which shall be transferred into the Tax Compliance and Administration Fund and shall be used by the Department, subject to appropriation, to cover the costs of the Department in administering the Innovation Development and Economy Act.
    After the monthly transfer to the STAR Bonds Revenue Fund, on or before the 25th day of each calendar month, the Department shall prepare and certify to the Comptroller the disbursement of stated sums of money to the Regional Transportation Authority and to named counties, the counties to be those entitled to distribution, as hereinabove provided, of taxes or penalties paid to the Department during the second preceding calendar month. The amount to be paid to the Regional Transportation Authority and each county having 3,000,000 or fewer inhabitants shall be the amount (not including credit memoranda) collected during the second preceding calendar month by the Department and paid into the County and Mass Transit District Fund, plus an amount the Department determines is necessary to offset any amounts which were erroneously paid to a different taxing body, and not including an amount equal to the amount of refunds made during the second preceding calendar month by the Department, and not including any amount which the Department determines is necessary to offset any amounts which were payable to a different taxing body but were erroneously paid to the Regional Transportation Authority or county, and not including any amounts that are transferred to the STAR Bonds Revenue Fund, less 2% of the amount to be paid to the Regional Transportation Authority, which shall be transferred into the Tax Compliance and Administration Fund. The Department, at the time of each monthly disbursement to the Regional Transportation Authority, shall prepare and certify to the State Comptroller the amount to be transferred into the Tax Compliance and Administration Fund under this Section. Within 10 days after receipt, by the Comptroller, of the disbursement certification to the Regional Transportation Authority, counties, and the Tax Compliance and Administration Fund provided for in this Section to be given to the Comptroller by the Department, the Comptroller shall cause the orders to be drawn for the respective amounts in accordance with the directions contained in such certification.
    When certifying the amount of a monthly disbursement to the Regional Transportation Authority or to a county under this Section, the Department shall increase or decrease that amount by an amount necessary to offset any misallocation of previous disbursements. The offset amount shall be the amount erroneously disbursed within the 6 months preceding the time a misallocation is discovered.
    The provisions directing the distributions from the special fund in the State Treasury provided for in this Section and from the Regional Transportation Authority tax fund created by Section 4.03 of the Regional Transportation Authority Act shall constitute an irrevocable and continuing appropriation of all amounts as provided herein. The State Treasurer and State Comptroller are hereby authorized to make distributions as provided in this Section.
    In construing any development, redevelopment, annexation, preannexation or other lawful agreement in effect prior to September 1, 1990, which describes or refers to receipts from a county or municipal retailers' occupation tax, use tax or service occupation tax which now cannot be imposed, such description or reference shall be deemed to include the replacement revenue for such abolished taxes, distributed from the County and Mass Transit District Fund or Local Government Distributive Fund, as the case may be.
