A sales tax refund is money the state or a business gives back when you have paid more sales tax than you owed
Sales tax refunds happen in two main situations. First, a state may refund sales tax you paid on items that turned out to be tax-exempt — things like groceries, prescription medications, or medical equipment that should never have been taxed in the first place. Second, a business refunds the sales tax portion of your purchase when you return an item for a refund. The refund includes both the item's price and the tax you paid on it.
The third, less common situation involves businesses or nonprofits that are registered to collect sales tax but should not have charged it to you because of your status — for example, a nonprofit organization making a tax-exempt purchase, or a reseller buying inventory for resale. In those cases, the business may refund the tax after you provide proof of your exemption.
Sales tax refunds are different from income tax refunds. You are not getting money back from the government because you overpaid during the year. Instead, you are getting back tax that was incorrectly charged or that should be returned as part of a purchase reversal.
Key Takeaways
- A sales tax refund returns money you paid in sales tax on a purchase, either because the item was tax-exempt or because you returned the item.
- When you return an item to a store, the refund should include the full purchase price plus the sales tax you paid, not just the pre-tax amount.
- If you were charged sales tax on an item that should have been exempt, you can request a refund from the business or, in some cases, from the state.
- Refunds for incorrectly charged tax usually take two to four weeks if you request them from the business, or longer if you file a claim with your state.
When a store charges you sales tax by mistake
Some items are legally exempt from sales tax in your state, but a cashier or checkout system charges it anyway. Common examples include unprepared food (groceries), prescription drugs, medical devices, and in some states, clothing or diapers. When this happens, you have the right to ask for the tax back.
The fastest way is to return to the store with your receipt and ask the customer service desk for a refund of the tax amount. Bring the receipt and, if possible, the item itself. Most stores will process this on the spot or within a few days. If the store refuses or if you no longer have the receipt, you can file a claim with your state's department of revenue, though this takes longer — typically four to eight weeks — and requires documentation that the item was tax-exempt under state law.
Keep your receipt. It shows the tax amount charged and the date of purchase, both of which you will need if the store does not refund it immediately.
Sales tax refunds when you return items
When you return an item to a store and receive a refund, the store should refund both the item price and the sales tax you paid. If the store only refunds the pre-tax amount and keeps the tax, you have been shortchanged.
Check your receipt or refund confirmation to see whether the tax was included. If it was not, ask the customer service desk to add it. Most stores will correct this without argument once you point it out. If the store refuses, contact the state's department of revenue or consumer protection office — they track complaints about stores that systematically fail to refund sales tax.
Online returns work the same way. When you return an item ordered online, the refund should include tax. If you paid tax on an order that was later cancelled or never shipped, the refund should include that tax as well.
How to request a refund from the state if the business won't pay
If a store refuses to refund sales tax you were incorrectly charged, or if you cannot locate the business, you can file a claim with your state's department of revenue. Each state has a different process, but most allow you to submit a form with your receipt, the date of purchase, the item description, and an explanation of why the tax should not have been charged.
Contact your state's department of revenue website directly — search "[your state] department of revenue sales tax refund" to find the right form and instructions. Some states process these claims within four weeks; others take two to three months. You will need documentation: your receipt, proof of purchase, and often a statement from the business explaining why they charged tax or why they will not refund it.
This route is slower than asking the store directly, so exhaust that option first. But if the business is unresponsive or has closed, the state can sometimes recover the tax for you or credit it against future purchases.
Sales tax refunds for businesses and resellers
If you are a registered reseller or a business buying inventory, you should not pay sales tax on those purchases. Instead, you provide the seller with a resale certificate or tax exemption number, and the seller does not charge tax. If you forget to provide the certificate and are charged tax anyway, you can request a refund from the business.
Bring your resale certificate and a copy of the receipt to the business's accounting or customer service department. Most businesses process these refunds within one to two weeks once they verify your exemption status. Keep copies of all resale certificates and receipts for your records — the IRS and state tax authorities may ask to see them during an audit.
Nonprofits and government agencies follow the same process. Provide proof of your tax-exempt status (usually a letter from the IRS or a state exemption certificate) and request a refund of any sales tax charged on purchases made for the organization's operations.
What happens if you paid sales tax on a tax-exempt purchase long ago
Most states have a time limit for requesting refunds of sales tax. This limit is usually between one and three years from the date of purchase, though it varies by state. If you discover you were overcharged years ago, you may still be able to recover the tax, but you need to act before the deadline passes.
Check your state's department of revenue website for the refund deadline and the process for filing an old claim. You will need the original receipt or a statement from the business showing the tax was charged. If you no longer have the receipt, some states will accept a credit card or bank statement showing the purchase, along with a written explanation of why the tax should not have been charged.
The longer ago the purchase was, the harder it is to prove. Start with the business itself — they may have records going back several years. If the business is no longer in operation, contact the state directly.
Sales tax refunds on online purchases and out-of-state orders
Online retailers are now required to collect sales tax in most states, even if the company is based out of state. If an online retailer charged you sales tax and later you discover the item was tax-exempt in your state, you can request a refund from the retailer using the same process as an in-store purchase: contact customer service with your order number and receipt.
If you ordered from a retailer that did not charge sales tax because they were not required to at the time, you may owe use tax to your state — a tax on purchases made out of state. Most states do not actively pursue individuals for use tax on small purchases, but the liability exists. This is different from a refund; it is a tax you may owe. Check your state's rules on use tax if you are unsure.
For refunds on online purchases, keep your order confirmation email and receipt. Most online retailers process refunds within five to ten business days, and the refund should include tax if the item was tax-exempt or if you returned it.
Frequently Asked Questions
Do I have to pay sales tax on groceries?
Most states do not charge sales tax on unprepared food like fruits, vegetables, bread, and milk. However, prepared foods (hot deli items, restaurant meals) are usually taxed. Some states tax all food; others exempt certain categories like baby food or dietary supplements. Check your state's rules, and if you were charged tax on an exempt item, request a refund from the store.
If I return something, do I get the sales tax back?
Yes. When you return an item for a refund, the store should refund the full amount you paid, including sales tax. If the refund receipt shows only the pre-tax price, ask the customer service desk to add the tax. Most stores correct this immediately once you point it out.
Can I get a refund if I lost my receipt?
You can try. If you paid by credit card or debit card, bring your bank statement showing the purchase. Some stores will refund tax based on the transaction alone. If the store refuses, you can file a claim with your state's department of revenue, though you will need to describe the item and explain why it should have been tax-exempt.
How long does it take to get a sales tax refund from the state?
State refunds typically take four to eight weeks, depending on how busy the department is and whether your claim is complete. Refunds from businesses usually come faster — one to four weeks. The timeline depends on whether you have all required documentation and whether the business or state needs to investigate your claim.
What if a business refuses to refund sales tax I was incorrectly charged?
Document the refusal in writing or by email if possible. Then contact your state's department of revenue or consumer protection office and file a complaint. You can also file a claim for the refund directly with the state, though this takes longer than asking the business first.
