Back-to-school sales tax holidays are already moving across the calendar, and the biggest mistake is assuming every school purchase will ring up tax-free. As of July 18, 2026, Alabama's holiday is in progress, Florida's monthlong window starts July 20, and several states have August weekends on the way.

The useful move is not to chase every sale. It is to check your state's exact dates, price caps and local rules before you buy bigger items like laptops, backpacks, shoes or school supplies.

State revenue agencies are the best source because the details vary. Alabama says its back-to-school holiday starts on the third Friday in July and runs through that Sunday, while local governments can decide whether to join the local-tax exemption. Florida's Department of Revenue says its 2026 holiday runs from July 20 through August 20 and covers categories such as clothing, school supplies, learning aids and personal computers only up to specific price limits.

Do this first

  • Check the date window. Alabama runs July 17-19 in 2026, Florida runs July 20-August 20, Arkansas runs August 1-2, and Ohio runs August 7-9. Texas also lists an annual back-to-school weekend for clothing, footwear, school supplies and backpacks priced under $100.
  • Read the price cap per item. Florida lists clothing and many bags at $100 or less, school supplies at $50 or less, learning aids at $30 or less, and personal computers or accessories at $1,500 or less for noncommercial home or personal use.
  • Do not assume local tax disappears. Alabama's state tax holiday does not automatically erase every county or city tax unless that locality participates.
  • Watch shipping and timing for online orders. Texas says qualifying items can be bought from online or catalog sellers doing business in the state. In many states, the order time and the total sales price can decide whether the exemption applies.

Check these details

Start with the state tax department page, not a retailer's banner. Retail ads can be useful reminders, but the official page tells you whether a backpack, computer accessory, textbook, lunch box or sports item qualifies. Some exclusions are easy to miss: Florida excludes several travel bags, watches, jewelry and video game consoles from its back-to-school holiday, while Ohio says its 2026 holiday is limited to back-to-school items and will not include the broader $500-and-under exemption that applied in an earlier expanded version.

For bigger purchases, compare the tax savings with the actual price. A tax-free laptop that is $75 more expensive than last week's sale is not a bargain just because the receipt removes sales tax. The same logic applies to clothing bundles: if each item must be under a cap, one over-limit pair of shoes can still be taxable even when the rest of the cart qualifies.

Common mistakes

Do not buy outside the window and expect a retroactive refund. Do not assume every bag is a school backpack. Do not assume every online seller handles the exemption correctly at checkout. If tax appears on a qualifying purchase during the holiday, save the receipt and check your state's refund instructions or ask the seller promptly.

Also check whether your state has no holiday at all. Many states skip back-to-school sales tax holidays, and some states have different holidays for emergency supplies, energy-efficient appliances or tools. A state-by-state list can help you plan, but the final answer should come from the state revenue agency for the place where the item is sold or delivered.

Bottom line

A sales tax holiday is most useful when you already know what you need. Make the list first, mark which items fit your state's caps, compare prices across retailers, and then use the holiday window for purchases that were already worth making.
