Do I have to pay sales tax on a used car?
How sales tax works on used cars
Sales tax on a used car is typically collected by the DMV when you register the vehicle, not at the point of sale. The tax is usually a percentage of the purchase price, but some states use a standardized value guide (like Kelly Blue Book) to prevent underreporting.
Rates vary by state and sometimes by county or city. For example, California's base rate is 7.25% plus local additions, while Oregon has no sales tax at all. New Hampshire, Montana, Alaska, Delaware, and Oregon generally don't charge sales tax on vehicle purchases, though other fees may apply.
If you buy from a dealer, they often collect the tax and handle registration. In private sales, you'll pay when you title and register the car. Some states offer credits if you traded in a vehicle, reducing the taxable amount.
- Tax is usually paid at registration, not to the seller.
- Rate depends on your state, county, and city.
- Some states use a value guide instead of the sale price.
- Dealers may collect tax; private sales require you to pay at the DMV.
- Trade-in credits can lower the taxable amount in some states.
What if you buy out of state?
If you buy a car in one state but register it in another, you typically pay sales tax in your home state when you register. However, some states have reciprocal agreements, and you might get credit for tax paid to the other state.
For example, if you buy in Arizona (5.6% tax) and register in California (7.25% base), California may charge the difference. Keep all receipts to prove what you paid.
Always check with your local DMV before buying out of state to avoid paying tax twice.
- You usually pay tax where you register the car.
- Some states credit tax paid elsewhere.
- Keep receipts to avoid double taxation.
- Rules vary—confirm with your DMV.
Common mistakes
- Thinking you can avoid sales tax by claiming a lower purchase price—many states use a value guide.
- Assuming the seller collects the tax in a private sale; usually you pay it at the DMV.
- Forgetting that local taxes can add to the state rate, increasing the total.
