Frequently Asked Questions
What taxes and fees do I pay when buying a car?
You'll typically pay state sales tax (0-10%+), registration fees, title transfer fees, plate fees, and dealer doc fees. Some states also charge county or city taxes. Our calculator covers all of these for every US state.
Do I pay sales tax on a trade-in?
It depends on your state. Many states offer a trade-in tax credit — you only pay sales tax on the difference between the new car price and your trade-in value. This can save hundreds or thousands of dollars.
What is a dealer doc fee?
A documentation fee (doc fee) covers the dealer's cost to process paperwork. It varies by state — some cap it ($75-$200), while others allow unlimited charges ($500-$1,000+). It's negotiable at most dealerships.
Which states have no sales tax on vehicles?
Five states have no sales tax: Alaska, Delaware, Montana, New Hampshire, and Oregon. However, some of these states charge higher registration fees or other vehicle-specific taxes. Always calculate the total drive-off cost, not just the sales tax rate.
Can I save money by buying a car in a different state?
Generally no. Most states require you to pay your home state's sales tax when you register the vehicle, regardless of where you bought it. Some states offer credits for taxes paid in another state, but you rarely save by crossing state lines to purchase.
