These are the rules for a new car bought from a dealer. Used-car and private-sale rules can differ. How we check this data.

Massachusetts charges 6.25% at the state level. That rate is higher than 35 states and lower than 13 states. County and city taxes may add to it, so check your local rate and enter the total in the calculator.

What to know in Massachusetts

Massachusetts charges 6.25% on vehicle purchases, and there are no local sales taxes on top, so that's the full rate wherever you live.

When you buy from a dealer, the tax is figured on the price minus your trade-in, so trading in lowers it. If you're weighing a private sale of your old car instead, remember to count the 6.25% of its value that you'd give up in tax savings.

Does Massachusetts tax your trade-in?

No. Massachusetts only taxes the difference between the new car's price and your trade-in. On a $35,000 car with a $10,000 trade-in, you'd pay $1,562.50 in state tax instead of $2,187.50, a saving of $625.00. That saving is worth counting when you compare a dealer's trade-in offer with selling the car yourself.

Example: a car loan in Massachusetts

A $35,000 car with $5,000 down, $1,500 in fees, and a 60-month loan at 6.5% APR ($2,187.50 state tax, rolled into the loan):

Rebates and fees

The calculator charges tax on the price before any manufacturer rebate. Ask the dealer how Massachusetts treats your specific rebate. Title, registration and dealer documentation fees vary, so ask for an itemized out-the-door price and put the fee total in the calculator.
