COLUMBUS, Ohio (WCMH) — The day, or days, that many parents have been waiting for has arrived, as students get ready to head back to the classroom.

Ohio’s annual tax-free weekend, a “sales tax holiday,” where parents can save money on clothing, backpacks and other school supplies, is happening August 6 through August 8.

It’s not a free-for-all, though. There are a few rules to follow. Here’s what you need to know before you start making your shopping list.

The items that qualify for tax exemption:

– Clothing priced $75 or less

– An item of school supplies priced $20 or less

– Or an item of school instructional material priced $20 or less

What about those of you who don’t wish to shop at a brick-and-mortar store?

The tax exemption does apply to online orders, if purchased during the tax-free weekend.

You will also not pay tax on shipping and handling if all your items in the shipment are eligible. For example, nothing is over the $20 limit for school supplies or the $75 limit for clothes.

Again, tax-free weekend runs Friday, August 6 through 11:59 Sunday, August 8.
