    Sec. 4. Taxes.
    (a) The board of commissioners of any county water commission may, by ordinance, impose throughout the territory of the commission any or all of the taxes provided in this Section for its corporate purposes. However, no county water commission may impose any such tax unless the commission certifies the proposition of imposing the tax to the proper election officials, who shall submit the proposition to the voters residing in the territory at an election in accordance with the general election law, and the proposition has been approved by a majority of those voting on the proposition.
    The proposition shall be in the form provided in Section 5 or shall be substantially in the following form:
---------------------------------------------------------------------------------------------------------------------
    Shall the (insert corporate
name of county water commission)           YES
impose (state type of tax or         ------------------------------------------------------------------------
taxes to be imposed) at the                NO
rate of 1/4%?
---------------------------------------------------------------------------------------------------------------------
    Taxes imposed under this Section and civil penalties imposed incident thereto shall be collected and enforced by the State Department of Revenue. The Department shall have the power to administer and enforce the taxes and to determine all rights for refunds for erroneous payments of the taxes.
    (b) The board of commissioners may impose a County Water Commission Retailers' Occupation Tax upon all persons engaged in the business of selling tangible personal property at retail in the territory of the commission at a rate of 1/4% of the gross receipts from the sales made in the course of such business within the territory. Beginning January 1, 2021, this tax is not imposed on sales of aviation fuel for so long as the revenue use requirements of 49 U.S.C. 47107(b) and 49 U.S.C. 47133 are binding on the District.
    The tax imposed under this paragraph and all civil penalties that may be assessed as an incident thereof shall be collected and enforced by the State Department of Revenue. The Department shall have full power to administer and enforce this paragraph; 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. In the administration of, and compliance with, this paragraph, the Department and persons who are subject to this paragraph shall have the same rights, remedies, privileges, immunities, powers and duties, and be subject to the same conditions, restrictions, limitations, penalties, exclusions, exemptions and definitions of terms, and employ the same modes of procedure, as are prescribed in Sections 1, 1a, 1a-1, 1c, 1d, 1e, 1f, 1i, 1j, 2 through 2-65 (in respect to all provisions therein other than the State rate of tax except that tangible personal property taxed at the 1% rate under the Retailers' Occupation Tax Act shall not be subject to tax hereunder), 2c, 3 (except as to the disposition of taxes and penalties collected, and except that the retailer's discount is not allowed for taxes paid on aviation fuel sold on or after December 1, 2019 and through December 31, 2020), 4, 5, 5a, 5b, 5c, 5d, 5e, 5f, 5g, 5h, 5i, 5j, 5k, 5l, 6, 6a, 6b, 6c, 6d, 7, 8, 9, 10, 11, 12, and 13 of the Retailers' Occupation Tax Act and Section 3-7 of the Uniform Penalty and Interest Act, as fully as if those provisions were set forth herein.
    Persons subject to any tax imposed under the authority granted in this paragraph may reimburse themselves for their seller's tax liability hereunder by separately stating the tax as an additional charge, which charge may be stated in combination, in a single amount, with State taxes that sellers are required to collect under the Use Tax Act and under subsection (e) of Section 4.03 of the Regional Transportation Authority Act, in accordance with such bracket schedules as the Department may prescribe.
    Whenever the Department determines that a refund should be made under this paragraph to a claimant instead of issuing a credit memorandum, the Department shall notify the State Comptroller, who shall cause the warrant 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 a county water commission tax fund established under subsection (g) of this Section.
    For the purpose of determining whether a tax authorized under this paragraph is applicable, 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 Federal Constitution as a sale in interstate or foreign commerce.
    If a tax is imposed under this subsection (b), a tax shall also be imposed under subsections (c) and (d) of this Section.
    No tax shall be imposed or collected under this subsection on the sale of a motor vehicle in this State to a resident of another state if that motor vehicle will not be titled in this State.
    Nothing in this paragraph shall be construed to authorize a county water commission 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.
    (c) If a tax has been imposed under subsection (b), a County Water Commission Service Occupation Tax shall also be imposed upon all persons engaged, in the territory of the commission, in the business of making sales of service, who, as an incident to making the sales of service, transfer tangible personal property within the territory. The tax rate shall be 1/4% of the selling price of tangible personal property so transferred within the territory. Beginning January 1, 2021, this tax is not imposed on sales of aviation fuel for so long as the revenue use requirements of 49 U.S.C. 47107(b) and 49 U.S.C. 47133 are binding on the District.
    The tax imposed under this paragraph and all civil penalties that may be assessed as an incident thereof shall be collected and enforced by the State Department of Revenue. The Department shall have full power to administer and enforce this paragraph; 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. In the administration of, and compliance with, this paragraph, the Department and persons who are subject to this paragraph shall have the same rights, remedies, privileges, immunities, powers and duties, and be subject to the same conditions, restrictions, limitations, penalties, exclusions, exemptions and definitions of terms, and employ the same modes of procedure, as are prescribed in Sections 1a-1, 2 (except that the reference to State in the definition of supplier maintaining a place of business in this State shall mean the territory of the commission), 2a, 3 through 3-50 (in respect to all provisions therein other than the State rate of tax except that tangible personal property taxed at the 1% rate under the Service Occupation Tax Act shall not be subject to tax hereunder), 4 (except that the reference to the State shall be to the territory of the commission), 5, 7, 8 (except that the jurisdiction to which the tax shall be a debt to the extent indicated in that Section 8 shall be the commission), 9 (except as to the disposition of taxes and penalties collected and except that the returned merchandise credit for this tax may not be taken against any State tax, and except that the retailer's discount is not allowed for taxes paid on aviation fuel sold on or after December 1, 2019 and through December 31, 2020), 10, 11, 12 (except the reference therein to Section 2b of the Retailers' Occupation Tax Act), 13 (except that any reference to the State shall mean the territory of the commission), the first paragraph of Section 15, 15.5, 16, 17, 18, 19, and 20 of the Service Occupation Tax Act as fully as if those provisions were set forth herein.
    Persons subject to any tax imposed under the authority granted in this paragraph may reimburse themselves for their serviceman's tax liability hereunder by separately stating the tax as an additional charge, which charge may be stated in combination, in a single amount, with State tax that servicemen are authorized to collect under the Service Use Tax Act, and any tax for which servicemen may be liable under subsection (f) of Section 4.03 of the Regional Transportation Authority Act, in accordance with such bracket schedules as the Department may prescribe.
    Whenever the Department determines that a refund should be made under this paragraph to a claimant instead of issuing a credit memorandum, the Department shall notify the State Comptroller, who shall cause the warrant 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 a county water commission tax fund established under subsection (g) of this Section.
    Nothing in this paragraph shall be construed to authorize a county water commission 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 the State.
    (d) If a tax has been imposed under subsection (b), a tax shall also be imposed upon the privilege of using, in the territory of the commission, any item of tangible personal property that is purchased outside the territory at retail from a retailer, and that is titled or registered with an agency of this State's government, at a rate of 1/4% of the selling price of the tangible personal property within the territory, as "selling price" is defined in the Use Tax Act. The tax shall be collected from persons whose Illinois address for titling or registration purposes is given as being in the territory. The tax shall be collected by the Department of Revenue for a county water commission. The tax must be paid to the State, or an exemption determination must be obtained from the Department of Revenue, before the title or certificate of registration for the property may be issued. The tax or proof of exemption may be transmitted to the Department by way of the State agency with which, or the State officer with whom, the tangible personal property must be titled or registered if the Department and the State agency or State officer determine that this procedure will expedite the processing of applications for title or registration.
    The Department shall have full power to administer and enforce this paragraph; to collect all taxes, penalties, and interest due hereunder; to dispose of taxes, penalties, and interest so collected in the manner hereinafter provided; and to determine all rights to credit memoranda or refunds arising on account of the erroneous payment of tax, penalty, or interest hereunder. In the administration of and compliance with this paragraph, the Department and persons who are subject to this paragraph shall have the same rights, remedies, privileges, immunities, powers, and duties, and be subject to the same conditions, restrictions, limitations, penalties, exclusions, exemptions, and definitions of terms and employ the same modes of procedure, as are prescribed in Sections 2 (except the definition of "retailer maintaining a place of business in this State"), 3 through 3-80 (except provisions pertaining to the State rate of tax, and except provisions concerning collection or refunding of the tax by retailers), 4, 11, 12, 12a, 14, 15, 19 (except the portions pertaining to claims by retailers and except the last paragraph concerning refunds), 20, 21, and 22 of the Use Tax Act and Section 3-7 of the Uniform Penalty and Interest Act that are not inconsistent with this paragraph, as fully as if those provisions were set forth herein.
    Whenever the Department determines that a refund should be made under this paragraph 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 a county water commission tax fund established under subsection (g) of this Section.
    (e) A certificate of registration issued by the State Department of Revenue to a retailer under the Retailers' Occupation Tax Act or under the Service Occupation Tax Act shall permit the registrant to engage in a business that is taxed under the tax imposed under subsection (b), (c), or (d) of this Section and no additional registration shall be required under the tax. A certificate issued under the Use Tax Act or the Service Use Tax Act shall be applicable with regard to any tax imposed under subsection (c) of this Section.
    (f) Any ordinance imposing or discontinuing any tax under this Section shall be adopted and a certified copy thereof filed with the Department on or before June 1, whereupon the Department of Revenue shall proceed to administer and enforce this Section on behalf of the county water commission as of September 1 next following the adoption and filing. Beginning January 1, 1992, an ordinance or resolution imposing or discontinuing the tax hereunder shall be adopted and a certified copy thereof filed with the Department on or before the first day of July, whereupon the Department shall proceed to administer and enforce this Section as of the first day of October next following such adoption and filing. Beginning January 1, 1993, an ordinance or resolution imposing or discontinuing the tax hereunder shall be adopted and a certified copy thereof filed with the Department on or before the first day of October, whereupon the Department shall proceed to administer and enforce this Section as of the first day of January next following such adoption and filing.
    (g) The State Department of Revenue shall, upon collecting any taxes as provided in this Section, pay the taxes over to the State Treasurer as trustee for the commission. The taxes shall be held in a trust fund outside the State Treasury.
    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 under this Section during the second preceding calendar month for sales within a STAR bond district.
    After the monthly transfer to the STAR Bonds Revenue Fund, on or before the 25th day of each calendar month, the State Department of Revenue shall prepare and certify to the Comptroller of the State of Illinois the amount to be paid to the commission, which shall be the amount (not including credit memoranda) collected under this Section during the second preceding calendar month by the Department plus an amount the Department determines is necessary to offset any amounts that were erroneously paid to a different taxing body, and not including any amount equal to the amount of refunds made during the second preceding calendar month by the Department on behalf of the commission, and not including any amount that the Department determines is necessary to offset any amounts that were payable to a different taxing body but were erroneously paid to the commission, and less any amounts that are transferred to the STAR Bonds Revenue Fund, less 1.5% of the remainder, which shall be transferred into the Tax Compliance and Administration Fund. The Department, at the time of each monthly disbursement to the commission, shall prepare and certify to the State Comptroller the amount to be transferred into the Tax Compliance and Administration Fund under this subsection. Within 10 days after receipt by the Comptroller of the certification of the amount to be paid to the commission and the Tax Compliance and Administration Fund, the Comptroller shall cause an order to be drawn for the payment for the amount in accordance with the direction in the certification.
