Missouri’s 8th Annual “Back-to-School” Sales Tax Holiday runs August 5th thru 7th, giving shoppers the opportunity to save money on clothes, computers and school supplies. Local governments can participate in the holiday and forego local sales tax collection, or can opt out of the holiday and maintain local tax revenue during the holiday. Morgan and Camden Counties are opting out, as are many cities and towns including Osage Beach, Camdenton, Eldon and Laurie. Lake Ozark and Miller County will participate in the Sales Tax Holiday. Under state law, the sales tax holiday begins on the first Friday in August and continues through the following Sunday. This year, the three-day holiday begins at midnight on Friday, August 5 and runs through Sunday, August 7. During this period, the state’s 4.225 percent sales tax will not be assessed on certain purchases.
