This year, Ohio’s sales tax holiday will run from midnight on August 1 until Aug. 14, at 11:59 p.m. And for 2025, state leaders expanded the annual sales tax holiday — ten days this year, as opposed to just three days in years past. Ohio sets aside at least three days each year (to include the first Friday, Saturday, and Sunday in August) for consumers to buy certain items without sales tax. This sales tax-free holiday helps families buy clothing, supplies, and more items their children may need to be successful in the coming school year. It allows tax-free purchases made in-person or online on all eligible items costing up to $500.
