The Texas sales tax holiday is Aug. 20-22 as shoppers prepare to head for stores the weekend before most public schools resume classes.
"As our economy continues to recover, this tax break will help families get more bang for their back-to-school bucks," said Texas Comptroller Susan Combs.
The Texas comptroller's office says the law exempts most clothing and footwear priced under $100 from sales and use taxes, which could save shoppers about $8 on every $100 they spend.
The agency says backpacks under $100 and used by elementary and secondary students are also exempt.
The 2009 Legislature expanded the list of items qualifying for tax exemption during the three-day weekend. Texas families get a sales tax break on most school supplies priced at less than $100 purchased for use by a student in an elementary or secondary school.
This year, Combs predicts shoppers will save $59.3 million in state and local sales taxes during the Sales Tax Holiday
