This calculator estimates Massachusetts motor vehicle sales/use tax you’ll owe when buying or receiving a vehicle (dealer sale, private-party sale, out-of-state purchase, gift, and common exemptions). You’ll need the price paid, whether it’s dealer/private/out-of-state/gift, and (for private sales) the NADA clean trade-in value if applicable. Massachusetts uses a 6.25% state sales/use tax rate with no local add-ons. Dealer document/title prep fees are generally part of the taxable sales price. Trade-ins can reduce the taxable amount when eligible, and rebates may reduce the taxable price only if applied at the time of sale. For private-party sales, Massachusetts guidance often compares the price paid to NADA clean trade-in value (with applicable adjustments), which can increase the taxable base. For out-of-state purchases, tax paid to another state may reduce MA use tax to the extent allowed by law. Verified January 28, 2026. Informational estimate only—use MA DOR/RMV rules and your transaction documents for official amounts.

FAQs

Is Massachusetts car sales tax always 6.25%?

Yes—MA’s state sales/use tax rate is 6.25%, with no local add-ons.

Why does MA sometimes tax a private sale above the bill of sale?

MA guidance references NADA clean trade-in value (with adjustments) for private sales, which can be higher than the price paid.

Are dealer doc/title prep fees taxable?

Generally yes—Massachusetts treats dealer document/title preparation fees as part of the taxable sales price.

Does a trade-in reduce the taxable amount?

Often yes—MA law provides a trade-in allowance that can reduce the taxable sales price when eligible.

My trade-in has a loan. Does that change the credit?

Trade-in credit is typically the trade-in value minus any debt encumbering it (payoff).

Do manufacturer rebates reduce MA vehicle sales tax?

If applied at the time of sale, rebates are generally treated as discounts; after-sale rebates typically don’t reduce taxable sales price.

I bought a car out of state and paid that state’s tax—do I still owe MA?

Possibly. If MA’s 6.25% rate is higher, you generally owe the difference (subject to conditions).

If I buy in a no-tax state like NH, what happens?

You generally owe MA use tax (6.25%) when registering/using the vehicle in MA, unless an exemption applies.

Is a gifted vehicle tax-free?

It can be if it qualifies as a true gift with required affidavit (MVU-24).

Is MA motor vehicle excise tax the same as sales tax?

No—excise tax is a separate annual local tax for registering a vehicle.
