You won’t see any of the parties, cakes or balloons usually associated with anniversaries as the Texas Sales Tax Holiday celebrates its 20th anniversary Aug. 9-11 — just the annual ringing of cash registers and clacking of fingers on keyboards.

Texans will be taking advantage of the state’s three-day suspension of state and local sales taxes on qualifying clothing, footwear and school supplies priced below $100 in stores and online.

Learn how this holiday has helped Texans save more than $1.3 billion in state and local taxes in the past two decades in the latest Line Items story from Fiscal Notes.

During this annual sales tax holiday, you can buy most clothing, footwear, school supplies and backpacks (sold for less than $100) tax free from a Texas store or from an online or catalog seller doing business in Texas. In most cases, you do not need to give the seller an exemption certificate to buy qualifying items tax free.

This year’s sales tax holiday begins Friday, Aug. 9, and goes through midnight Sunday, Aug. 11.

The sales tax exemption applies only to qualifying items you buy during the sales tax holiday. Items you buy before or after the sales tax holiday do not qualify for exemption, and there is no tax refund available.
