Texas shoppers get a break from state and local sales taxes Aug 20-22, the state's annual tax holiday.

Parents all across the state whose children are heading back to school are also being reminded that lay-away plans can be used again this year to take advantage of the sales tax holiday.

As in previous years, 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. Backpacks under $100 and used by elementary and secondary students are also exempt.

A backpack is a pack with straps one wears on the back. The exemption during the sales tax holiday includes backpacks with wheels, provided they can also be worn on the back like a traditional backpack, and messenger bags.

The exemption does not include items that are reasonably defined as luggage, briefcases, athletic/duffle/gym bags, computer bags, purses or framed backpacks. Ten or fewer backpacks can be purchased tax-free at one time without providing an exemption certificate to the seller.

No exemption certificate is required - with one exception. If the purchaser is buying the supplies under a business account, the retailer must obtain an exemption certificate from the purchaser certifying that the items are purchased for use by an elementary or secondary school student.

"Under a business account" means the purchaser is using a business credit card or business check rather than a personal credit card or personal check; being billed under a business account maintained at the retailer; or is using a business membership at a retailer that is membership based.
