For over a decade, Texas shoppers have taken advantage of the back-to-school sales tax holiday. This period allows for you to purchase all of those school supplies and outfits tax-free before the start of the new school year. These costs really add up for families, especially for those with multiple children. The sales tax holiday is a good opportunity for families to save ahead of the school year. This year’s sales tax holiday falls on August 7th, 8th and 9th.
