16 states offer tax-free weekends to help with school shopping. Is yours one of them?

For 20 years, bargain-hunting parents in South Carolina have saved money on clothing, school supplies and computers right before sending their kids back to the classroom. That’s because the Palmetto State is one of 16 in the country that holds annual back-to-school sales tax “holidays.” Typically held on a weekend in August, the state sales tax is waived on certain school-related items.

The promotion is a boon for people who live in states with a high combined state and local sales tax. According to the Tax Foundation, Tennessee (9.53{a38ddb2ded6b05e28c8ae73a8db0e271c21f7193684bd9e4e28acae292f81d99}), Arkansas (9.47{a38ddb2ded6b05e28c8ae73a8db0e271c21f7193684bd9e4e28acae292f81d99}) and Alabama (9.22{a38ddb2ded6b05e28c8ae73a8db0e271c21f7193684bd9e4e28acae292f81d99}) are at the top of the list.

In South Carolina, where the state and local sales tax can reach a total of 7.46{a38ddb2ded6b05e28c8ae73a8db0e271c21f7193684bd9e4e28acae292f81d99} , consumers in past years have saved between $2 million and $3 million over the sales tax-free weekend, according to the state’s tax-free holiday website.

Five states — Alaska, Delaware, Montana, New Hampshire and Oregon — don’t need a holiday. There is no sales tax in these states, according to Kiplinger. That’s a perk for residents and those who live near their borders.

Here is a rundown of states with sales tax holiday events this summer. Note that some counties or municipalities may not participate. Check the sales’ start and end times; some events begin at 12:01 a.m. on the first day and end at midnight on the last. Visit your state’s tax website for updates before you shop.
