If you paid sales tax in one state on something you’re bringing home to another, most states give you a credit for sales tax paid to another state against the use tax you would otherwise owe at home. The credit is dollar for dollar, capped at what your home state would charge. Pay less than your home rate and you owe the difference; pay the same or more and you owe nothing further, though you don’t get the extra back.
How the Credit Is Calculated
The math is simple. Compare what you paid in the selling state to what your home state would charge on the same purchase, and credit the smaller of the two figures against your home use tax.
- You paid less than your home rate. You owe the difference. Pay 5% on a $10,000 item ($500) and your home state charges 7%, and your use tax bill is $700 minus the $500 credit, leaving $200 due.
- You paid the same or more than your home rate. The credit wipes out the home state’s use tax and you owe nothing additional. Pay 8% ($800) where your home state charges 6% ($600) and you have no remaining obligation. You don’t get the extra $200 refunded, though. That money stays with the state that collected it.
The practical result: you pay at least the higher of the two rates, but never both stacked together.
When the Credit Applies
The tax you paid must have been legally owed under the other state’s law. This is sometimes called the “legally due and paid” standard. If the selling state actually exempted the transaction, or the seller collected tax in error, your home state can deny the credit because you weren’t legally required to pay in the first place. The remedy in that case is a refund request from the state that overcollected, not a credit at home.
The credit traditionally covers tangible personal property: furniture, electronics, appliances, equipment, and most commonly vehicles. Some states have extended their use tax to digital goods, software subscriptions, and certain services, and the credit rules follow along.
Five states have no statewide sales tax at all: Alaska, Delaware, Montana, New Hampshire, and Oregon. Residents of those states generally have no use tax obligation and no need for a credit. Buyers from other states who purchase there and take the goods home may owe full use tax at home, with no credit to offset it, because no sales tax was paid.
Local Tax Complications
Many states layer county and city sales taxes on top of the state rate, and how these interact with the credit varies. Some states credit the full combined state-and-local tax you paid elsewhere. Others credit only the state-level portion. The Multistate Tax Compact directs that any unused credit after satisfying state use tax should be applied against local use tax, and specifies that a purchaser owing use tax on tangible personal property “shall be entitled to full credit for the combined amount or amounts of legally imposed sales or use taxes paid” to another state or its local jurisdictions.1Multistate Tax Commission. Multistate Tax Compact Not every state follows that approach, so check your home state’s guidance when local rates are in play.
Vehicles: Where Most People Encounter This
Vehicles are the most common reason to claim the credit, because the dollar amounts are large and the tax gets collected at a chokepoint: registration. When you buy a car in another state and bring it home, your state’s motor vehicle or tax agency assesses use tax before issuing title and registration. You can’t quietly skip it the way some people do with smaller items.
To claim the credit on a vehicle, you’ll typically need the purchase agreement or bill of sale, proof that sales tax was paid (usually the dealer’s invoice or a receipt from the other state’s tax authority), and in some states a use tax affidavit. The credit reduces or eliminates the use tax portion of your registration costs. If the selling state’s rate was lower, you pay the difference at the registration window.
One thing to watch: some states impose flat title fees or environmental surcharges that are separate from use tax. The out-of-state credit only offsets the tax itself, not those add-on fees.
How to Claim the Credit on Other Purchases
For non-vehicle purchases, states generally use one of two methods.
- On your state income tax return. Many states include a use tax line on the individual return. You report the purchase price, calculate the use tax, and subtract the credit for tax paid elsewhere on the same form. This is the most common route.
- On a separate consumer use tax return. Some states require a standalone form, especially when the amount owed exceeds a threshold or must be reported within a set window after the purchase.
Most states offer online filing. If you file by mail, send copies of your receipts rather than originals.
Documentation You’ll Need
The credit only works if you can prove what you paid. Keep the original sales receipt or dealer invoice showing the purchase price, the amount of tax collected, and the jurisdiction that received it. For vehicles, the bill of sale and any title paperwork from the selling state serve the same purpose. If your receipts don’t break out the tax as a separate line, bank or credit card statements showing the total can serve as backup.
Hold onto these records for at least three to four years. The IRS recommends keeping tax records for three years in most situations and four years for employment-related taxes.2Internal Revenue Service.

If You Never Paid Use Tax in the First Place
Use tax is technically owed whether or not anyone reminds you. For vehicles and other titled property, the tax is caught at registration. For furniture, electronics, and other untitled items, many consumers don’t report, and the Supreme Court has described consumer compliance with use tax obligations as “notoriously low.”3Congress.gov.

If a state catches an underpayment, you’ll owe the original tax plus penalties and interest. Penalties for failing to file or pay use tax typically range from 5% to 25% of the unpaid tax, and interest accrues on top of that, commonly between 7% and 11% annually.
The point that matters for credit purposes: if you owed use tax and didn’t pay it, you can still claim the credit for tax paid to the other state when you eventually settle up. The penalty and interest apply to the net amount you should have paid after the credit, not to the full purchase price. Squaring things up voluntarily before an audit often reduces or eliminates the penalty portion.
Why Online Purchases Rarely Trigger This Anymore
Before 2018, online retailers with no physical presence in your state weren’t required to collect sales tax, leaving consumers to self-report use tax. The Supreme Court’s 2018 decision in South Dakota v. Wayfair let states require remote sellers to collect sales tax based on their economic activity in the state, even without a physical presence.3Congress.gov.

Today, most major online retailers and marketplace platforms collect sales tax at checkout based on your shipping address, meaning the tax already goes to your home state and no credit claim is needed. The credit mechanism now matters mostly for in-person purchases made in another state: buying a car on a trip, picking up furniture at an out-of-state store, or buying equipment at a trade show. If a smaller online seller happens to collect another state’s tax instead of yours, the credit still applies the same way.
The principle that you shouldn’t pay tax twice on the same purchase is so basic to interstate commerce that virtually every state with a sales tax recognizes the credit in some form. The specifics vary enough, though, that a quick check of your home state’s department of revenue guidance is worth doing before you file, especially when local rates or a vehicle are involved.
