Massachusetts Has One Simple Sales Tax — and a Second Tax Most Buyers Forget

Massachusetts charges a flat 6.25% sales tax on vehicle purchases, with no city or county add-on anywhere in the state. That part is simple: a $35,000 car owes exactly $2,187.50 in sales tax, whether you buy in Boston or the Berkshires.

What trips buyers up is a second, completely separate tax: the annual motor vehicle excise tax, billed by your city or town every year you own the car. This isn't part of your out-the-door price at the dealership — it arrives later as a municipal bill — but it's a real, recurring cost that catches new Massachusetts car owners off guard.

The excise tax rate is $25 per $1,000 of the vehicle's assessed value, which starts at 90% of MSRP in the year of manufacture and steps down in later years (50% the year before manufacture, 60% in year two, 40% in year three, 25% in year four, and 10% from year five onward).

On a new $35,000 car, first-year assessed value is roughly $31,500 (90% of MSRP), putting the first excise bill near $787.50. That bill shrinks substantially as the vehicle ages — by year five it's typically under $100.

Frequently Asked Questions

What is the car sales tax in Massachusetts?

Massachusetts charges a flat 6.25% sales tax on vehicle purchases, with no city or county add-on anywhere in the state. It's one of the simpler states to calculate — the rate never changes based on location.

What is the Massachusetts motor vehicle excise tax?

It's a separate annual tax billed by your city or town, not collected at purchase. The rate is $25 per $1,000 of the vehicle's assessed value, which starts near 90% of MSRP and steps down each year as the car ages.

Is the excise tax included in my out-the-door price?

No. The excise tax is billed annually and separately by your municipality after you register the vehicle — it isn't part of what you pay at the dealership. Our calculator shows your purchase-time total; budget for the excise bill separately each year.

Does Massachusetts tax trade-ins?

Yes. Your trade-in value is subtracted from the purchase price before the 6.25% sales tax is calculated, lowering your total tax proportionally, the same as most other states.

Is there a doc fee cap in Massachusetts?

No. Massachusetts does not cap dealer documentation fees by statute, so amounts vary by dealer — it's worth asking for a reduction before you sign.
