The sticker isn’t the price. Enter your numbers and get an itemized breakdown — tax, title, and fees included — so you can give it a proper side-eye before you ever sit down.

How to use it: enter the agreed price, pick your state, add your trade and financing — the out-the-door total builds line by line in The Math.

Massachusetts keeps it flat: 6.25% statewide on vehicles, no city or town add-ons anywhere from the Berkshires to the Cape. Your trade-in reduces the taxable amount in full on dealer purchases, so a $32,000 purchase with an $8,000 trade is taxed on $24,000 — an even $500 saved at the state rate.

One Massachusetts habit to know: the state is strict about taxing private-party sales on fair value, not just claimed price. Report a suspiciously low price on a private sale and the RMV will assess tax on the vehicle's book value instead (typically NADA clean trade-in value). Genuine bargains happen, but the paperwork price and the market price can't drift too far apart without the state noticing.

Doc fees are uncapped and typically run $400–500 here. And a budgeting note beyond the purchase itself: Massachusetts levies an annual motor vehicle excise tax of $25 per $1,000 of the car's (depreciated) value, billed by your city or town — roughly $600 in year one on a $30,000 car, declining each year. It's not part of the out-the-door price, but it's a real cost of ownership that catches first-time Massachusetts buyers off guard.

Every figure above was last verified against official Massachusetts sources in July 2026. Tax rules do change — the final word is always your paperwork and the DMV.
