Trade-In Tax Savings Calculator
A dealer's trade-in offer is often lower than a private sale price, but in most states the trade-in also cuts your sales tax. This calculator adds that saving to the offer so you can compare the two fairly.
Selling it yourself for $13,500 would leave you about $750.00 ahead, before the time and hassle of a private sale.
Why the tax credit changes the math
When you trade in, most states tax only the difference between the new car's price and the trade-in. A $12,000 trade-in in a state with a 7% rate saves $840 of tax, so the offer is really worth $12,840. Selling the old car yourself for $13,000 would leave you only $160 ahead.
The saving depends entirely on your state. It's zero in California and Virginia, limited to $12,000 of trade value in Michigan, and in Ohio it applies only when you buy a new car. Our trade-in credit guide lists every state.
FAQ
Do you pay sales tax on a trade-in?
In most states you pay tax only on the difference between the new car's price and your trade-in, so the trade-in itself saves tax. California and Virginia don't give that credit, and Michigan caps it.
Is it better to trade in or sell privately?
Compare the private sale price with the dealer's offer plus the tax the trade-in saves. If the private price is higher than that total, selling yourself comes out ahead before counting the time it takes.
Does a trade-in with a loan still save tax?
In the states we've checked, the credit is the trade-in allowance, not your equity, so a loan payoff doesn't reduce it. Massachusetts says this explicitly.
