Frequently Asked Questions

What is vehicle sales tax?

Vehicle sales tax is a consumption tax paid to state and local governments when purchasing a vehicle. The tax is calculated as a percentage of the vehicle's purchase price and varies by state and locality.

How is car sales tax calculated?

Car sales tax is calculated by multiplying the taxable amount (purchase price minus trade-in value) by the applicable tax rate. Most states have a base state rate plus additional local taxes that vary by county or city.

Do I pay sales tax on trade-in value?

No, in most states you only pay sales tax on the net purchase price after subtracting your trade-in value. This can result in significant savings when trading in a vehicle.

Which states have no vehicle sales tax?

Five states have no statewide sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, some local jurisdictions in these states may still impose local sales taxes on vehicle purchases.

When do I pay vehicle sales tax?

Vehicle sales tax is typically paid when you register the vehicle and transfer the title. For dealer purchases, the dealer often collects the tax at the time of sale. For private party sales, you pay when registering the vehicle.

Can I deduct vehicle sales tax on my taxes?

You may be able to deduct state and local sales taxes, including vehicle sales tax, on your federal tax return if you itemize deductions. You can choose to deduct either state income tax or sales tax, but not both.

How do local taxes affect my vehicle sales tax?

Many states allow counties, cities, or other local jurisdictions to impose additional sales taxes on vehicle purchases. These local taxes are added to the state rate and can significantly increase your total tax burden.
