OKLAHOMA CITY (AP) — An Oklahoma lawmaker says he wants to change the state's back-to-school sales tax holiday law to provide more tax relief on the purchase of school supplies.

The annual sales tax holiday occurs during the first weekend in August and is scheduled this year from Aug. 5 through Aug. 7. But House Democratic Leader Scott Inman of Del City says tax-free items include costumes, girdles, formal wear and wedding apparel instead of backpacks, crayons or erasers.

Inman says lawmakers adopted the sales tax holiday in 2007 to help families save money on purchases before the start of fall classes. He says changes are needed to get back to the original spirit of the law.

Oklahoma is one of 15 states with clothing sales tax holidays. Ten have school supplies tax holidays.
