66.630. Taxes on motor vehicles, trailers, boats and outboard motors — how collected and distributed (St. Louis County). — 1. County sales taxes imposed pursuant to sections 66.600 to 66.630 on the purchase and sale of motor vehicles, trailers, boats, and outboard motors shall not be collected and remitted by the seller, but shall be collected by the director of revenue at the time application is made for a certificate of title, if the address of the applicant is within a county imposing a county sales tax. The amounts so collected, less the one percent collection cost, shall be deposited in the county sales tax trust fund to be distributed in accordance with section 66.620 until March 31, 1988. Beginning April 1, 1988, seventy-five percent of the distributable sales tax revenue shall be distributed in accordance with section 66.620 . The remaining twenty-five percent of the distributable sales tax revenue shall be held in an interest-bearing account and, less annual costs of distribution, shall be distributed monthly to each city, town or village and the county based upon the number of transactions occurring within each city, town or village and the unincorporated area of the county during the preceding month as reported to the department of revenue in the monthly dealer sales report subject, however, to the redistribution formula defined in section 66.620 and, except that any city, town or village and the county contained in group B as defined in section 66.620 shall have distributed to it by the director of revenue its share of the remaining twenty-five percent as calculated herein in accordance with section 66.620 . The cost incurred by the department of revenue for distribution shall be paid by each city, town or village in proportion to the number of transactions occurring within its boundaries and shall be deducted annually from such distributable revenue. In the event that an alternative distribution system is adopted pursuant to section 67.581 , all of the moneys collected under this section shall be distributed in accordance with that formula. The purchase or sale of motor vehicles, trailers, boats, and outboard motors shall be deemed to be consummated at the address of the applicant.
