Buying a car in Massachusetts.

By The Model Black · Updated October 7, 2026

Massachusetts charges sales and use tax of 6.25% statewide on vehicles, with no local add-on. A trade-in does reduce the taxable price, which is real money on the deal.

Lease

To see a lease, pick a vehicle. A lease is priced on one car: what it is expected to be worth at the end (its residual) and the leasing company's money factor change by model and by month.

Pick a vehicleHow leasing works

An estimate on the numbers you type, not an offer of credit or a quote from any dealership. Starting loan rates are Rateous's rates for each credit range and term; they are not an offer from any lender. The documentary fee starts at an example figure, the state's legal cap where it has one or $599 where it does not, not any dealership's fee; each dealership sets its own. Taxes and state fees are estimates for Massachusetts; the dealership's paperwork and your motor vehicle agency have the final numbers. Nothing you type is sent, saved, or used to check your credit.

How the tax works.

No local sales tax in Massachusetts.

Manufacturer rebates do not reduce the taxable sales price (the rebate is consideration paid by a third party); dealer discounts do.

Sales tax on a dealer sale is paid to the RMV when the vehicle is registered (within 10 days), based on the actual price.

Trade-ins: Trade-in of a motor vehicle to a registered dealer reduces the taxable sales price (M.G.L. c. 64H, s. 26).

Title, registration and fees.

On a $35,000 new car with a $37,000 sticker, registered in Boston, no trade-in: the same figures the calculator above uses. The dealership's documentary fee is its own and is not included.

FeeAmount
Title fee$75.00
Registration (est., flat based)$60.00
In all$135.00
Passenger registration $60 for a two-year term (plates included).
Annual value-based tax: Motor vehicle excise tax. $25 per $1,000 of value; value = MSRP x 90% in the model year, 60% year 2, 40% year 3, 25% year 4, 10% thereafter. Billed annually by the city or town; a $40,000 car owes $900 in the model year.

Leasing in Massachusetts.

Massachusetts taxes a lease one payment at a time: the tax is added to each monthly payment, so you pay it as you go.
