1. All city sales taxes collected by the director of revenue under sections 94.500 to 94.550 on behalf of any city, less one percent for cost of collection which shall be deposited in the state‘s general revenue fund after payment of premiums for surety bonds as provided in section 32.087, shall be deposited with the state treasurer in a special trust fund, which is hereby created, to be known as the “City Sales Tax Trust Fund”. The moneys in the city sales tax trust fund shall not be deemed to be state funds and shall not be commingled with any funds of the state. The director of revenue shall keep accurate records of the amount of money in the trust fund which was collected in each city imposing a city sales tax, and the records shall be open to the inspection of officers of the city and the public. Not later than the tenth day of each month the director of revenue shall distribute all moneys deposited in the trust fund during the preceding month, to the city treasurer, or such other officer as may be designated by the city ordinance, of each city imposing the tax authorized by sections 94.500 to 94.550, the sum due the city as certified by the director of revenue.

2. The director of revenue may authorize the state treasurer to make refunds from the amounts in the trust fund and credited to any city for erroneous payments and overpayments made, and may redeem dishonored checks and drafts deposited to the credit of such cities. If any city abolishes the tax, the city shall notify the director of revenue of the action at least ninety days prior to the effective date of the repeal and the director of revenue may order retention in the trust fund, for a period of one year, of two percent of the amount collected after receipt of such notice to cover possible refunds or overpayment of the tax and to redeem dishonored checks and drafts deposited to the credit of such accounts. After one year has elapsed after the effective date of abolition of the tax in such city, the director of revenue shall authorize the state treasurer to remit the balance in the account to the city and close the account of that city. The director of revenue shall notify each city of each instance of any amount refunded or any check redeemed from receipts.
