AUSTIN, Texas (AP) - The annual Texas sales tax break weekend will be Aug. 21-23 as students prepare to return to school and other shoppers also benefit.

The state comptroller's office says the law exempts most clothing and footwear priced under $100 from sales and use taxes.

The agency says backpacks under $100 and used by elementary and secondary students are also exempt. The item is defined as a pack with straps, for wearing on the back.

The 2009 Legislature expanded the items exempt from state, local and use taxes during the Aug. 21-23 period to include most school supplies costly less than $100.

Examples of exempt school supplies are calculators, lunch boxes, notebooks and markers.

Tax-free clothing items include coats, dresses, jackets, jeans, pants, boots, shirts and shoes.
