The 2026 Texas sales tax holiday begins Friday, August 7, and runs through Sunday, August 9. During that weekend, you won’t pay sales tax on most clothing, shoes, school supplies and backpacks that are priced under $100. A Little Planning Could Save You Even MoreIn an effort to attract you to their stores during the sales tax holiday, many retailers will also mark down clothing, backpacks and school supplies. It also needs to be made clear that the qualifying items must be purchased during the actual sales tax holiday. Of course, you’re not really saving money if you’re buying a bunch of unnecessary stuff just because it’s tax-free.
