Section 67.1925 - Special trust fund created1. All revenue received by a county from the tax authorized pursuant to the provisions of section 67.1922 shall be deposited in a special trust fund, and be used solely for the purposes specified in the proposal submitted pursuant to subsection 1 of section 67.1922 for so long as the tax shall remain in effect.2. Once the tax authorized pursuant to the provisions of section 67.1922 is abolished or terminated by any means, all funds remaining in the special trust fund shall be used solely for activities initiated with revenues raised by the tax authorized. Any funds in such special trust fund which are not needed for current expenditures may be invested by the governing body in accordance with applicable laws relating to the investment of other county funds.3. All sales taxes collected by the director of revenue pursuant to section 67.1922 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 in a special trust fund, which is hereby created, to be known as the "Economic Development Sales Tax Trust Fund". The moneys in the economic development 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 and which was collected in each county imposing a sales tax pursuant to this section, and the records shall be open to inspection by officers of the county 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 county which levied the tax; such funds shall be deposited with the county treasurer of each such county, and all expenditures of funds arising from the local economic development trust fund shall be by an appropriation act to be enacted by the governing body of such county. Expenditures may be made from the fund for any purposes authorized pursuant to subsection 1 of section 67.1922, provided water quality programs receive one-third, infrastructure programs receive one-third and tourism programs receive one-third; and provided no more than five percent of the total fund shall be used annually for administration costs.4. The director of revenue may authorize the state treasurer to make refunds from the amounts in the trust fund and credit any county for erroneous payments and overpayments made, and may redeem dishonored checks and drafts deposited to the credit of such counties. If any county abolishes the tax, the county 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 county, the director of revenue shall remit the balance in the account to the county and close the account of that county. The director of revenue shall notify each county of each instance of any amount refunded or any check redeemed from receipts due the county.5. Except as modified in this section, all provisions of sections 32.085 and 32.087 shall apply to the tax imposed pursuant to section 67.1922.
