(35 ILCS 525/10-15)
    Sec. 10-15. Filing of returns and deposit of proceeds. On or before the last day of each calendar month, every operator engaged in the business of providing to purchasers parking areas and garages in this State during the preceding calendar month and every booking intermediary required to collect tax under Section 10-10 shall file a return with the Department, stating:
        (1) the name of the operator or booking intermediary;
        (2) the address of its principal place of business
    
and, if applicable, the address of the principal place of business from which it provides parking areas and garages in this State;
        (3) the total amount of receipts received by the
    
operator during the preceding calendar month or quarter, as the case may be, from sales of parking spaces to purchasers in parking areas or garages during the preceding calendar month or quarter; the total amount of receipts for separately stated service fees that are charged to the customer by the booking intermediary in connection with the booking intermediary's facilitation of parking spot reservations for an operator during the preceding calendar month or quarter, as the case may be; and, if the return is filed by a booking intermediary that collects the tax under this Act on behalf of an unregistered operator, as provided in Section 10-10, then the total amount of receipts received by the booking intermediary on behalf of the unregistered operator during the preceding calendar month or quarter, as the case may be, from sales of parking spaces to purchasers in parking areas or garages during the preceding calendar month or quarter;
        (4) deductions allowed by law;
        (5) the total amount of receipts received by the
    
operator during the preceding calendar month or quarter upon which the tax was computed; the total amount of receipts for separately stated service fees that are charged to the customer by a booking intermediary in connection with the booking intermediary's facilitation of parking spot reservations for an operator during the preceding calendar month or quarter upon which the tax was computed; and, if the return is filed by a booking intermediary that collects the tax under this Act on behalf of an unregistered operator, as provided in Section 10-10, then the total amount of receipts received by the booking intermediary on behalf of the unregistered operator during the preceding calendar month or quarter upon which the tax was computed;
        (6) the amount of tax due; and
        (7) such other reasonable information as the
    
Department may require.
    If an operator or booking intermediary ceases to engage in the kind of business that makes it responsible for filing returns under this Act, then that operator or booking intermediary shall file a final return under this Act with the Department on or before the last day of the month after discontinuing such business.
    All returns required to be filed and payments required to be made under this Act shall be by electronic means. Taxpayers who demonstrate hardship in filing or paying electronically may petition the Department to waive the electronic filing or payment requirement, or both. The Department may require a separate return for the tax under this Act or combine the return for the tax under this Act with the return for other taxes. In addition to the requirement to file all returns required to be filed and payments required to be made under this Act by electronic means, booking intermediaries shall file returns in the form and manner required by the Department.
    If the same person has more than one business registered with the Department under separate registrations under this Act, that person shall not file each return that is due as a single return covering all such registered businesses but shall file separate returns for each such registered business.
    If the operator or booking intermediary is a corporation, the return filed on behalf of that corporation shall be signed by the president, vice-president, secretary, or treasurer, or by a properly accredited agent of such corporation.
    The operator or booking intermediary filing the return under this Act shall, at the time of filing the return, pay to the Department the amount of tax imposed by this Act less a discount of 1.75%, not to exceed $1,000 per month, which is allowed to reimburse the operator or booking intermediary for the expenses incurred in keeping records, preparing and filing returns, remitting the tax, and supplying data to the Department on request.
    If any payment provided for in this Section exceeds the taxpayer's liabilities under this Act, as shown on an original return, the Department may authorize the taxpayer to credit such excess payment against liability subsequently to be remitted to the Department under this Act, in accordance with reasonable rules adopted by the Department. If the Department subsequently determines that all or any part of the credit taken was not actually due to the taxpayer, the taxpayer's discount shall be reduced by an amount equal to the difference between the discount as applied to the credit taken and that actually due, and that taxpayer shall be liable for penalties and interest on such difference.
