New Hampshire Used Car Sales Tax: None, but Town Permit and Title Fees

New Hampshire has no sales tax on used cars, from a dealer or a private seller. What you pay instead is a town or city permit fee when you register, figured from the car's original list price and its age, plus a state registration fee by weight and a $35 title fee. On an older car that's usually a modest bill. The trap is for Massachusetts residents: buying in New Hampshire doesn't get you out of Massachusetts tax.

I checked the New Hampshire Department of Revenue Administration's FAQ, the current text of RSA 261 on the General Court's site, and the motor vehicle fee pages for Nashua and Exeter on Oct 20, 2026. Treat every fee below as a snapshot as of that date. The example math is mine.

No sales tax, but a local permit fee

The DRA's FAQ answers the basic question in one line: "No, there is no general sales tax on goods purchased in New Hampshire." Cars aren't an exception. The cost that takes its place is the municipal permit fee in RSA 261:153, which you pay to your town clerk or city when you register. It's charged in mills, meaning dollars per $1,000 of the maker's list price:

• 18 mills for a current model year vehicle
• 15, 12, 9 and 6 mills for the first through fourth preceding model years
• 3 mills for the fifth preceding model year and anything older

The fee can't be less than $5. The statute also uses a "straight line" method, so a car steps down one mill rate for each 12 months it has been registered, counted from its first registration. In practice, an old car sits at the bottom rate.

My own example: a used car with a $30,000 original list price that's five or more model years old pays 3 mills, or $90 to the town. The same list price at the 18-mill rate would be $540. That's why a nearly new used car costs a lot more to register here than an older one.

State fees, title and town add-ons

On top of the town permit, RSA 261:141 as posted on Oct 20, 2026 sets the state registration fee for most passenger vehicles at $42 up to 3,000 pounds, $48 from 3,001 to 5,000 pounds and $66 from 5,001 to 8,000 pounds. That section was amended in 2025 and twice in 2026, and Exeter's fee page still listed older, lower figures when I checked, so don't be surprised if a town website lags the statute.

The title application fee under RSA 261:20 went from $25 to $35 on Jan. 1, 2026. Nashua lists $37, which is the $35 state fee plus a $2 municipal agent fee. One quirk helps buyers of old cars: RSA 261:3 exempts any vehicle with a model year before 2000 from titling, except heavy trucks over 18,000 pounds. That means a 1998 car may change hands on a bill of sale and the old registration, which makes a history check matter even more. Our New Hampshire title transfer guide covers the paperwork.

Towns can also add small fees. RSA 261:153 lets them collect a reclamation fee and a transportation improvement fee of up to $5. Exeter, for example, lists a $4 transportation fee and a $3 municipal agent fee, and registers new vehicles to the owner's birth month. Finishing my $30,000 example in a town like Exeter for a 3,500-pound car: $90 town permit, $48 state, $35 title, plus a handful of dollars in local fees. Call it roughly $180 to $190, not counting plates.

If you live in Massachusetts

This is where people get burned. Massachusetts' motor vehicle sales and use tax guide (updated Sept. 15, 2022) says the 6.25% tax applies when a vehicle is bought in another state and brought into Massachusetts within six months for permanent use (its own example is a car bought in New Hampshire), and it gives credit only for tax paid to a state that offers Massachusetts the same courtesy. New Hampshire charges nothing, so you get no credit. On a private sale, Massachusetts taxes the higher of the price paid or the clean trade-in (book) value, and the trade-in credit doesn't apply to casual sales. Our Massachusetts used car sales tax guide runs through that math. The savings only applies if you really live in New Hampshire.

Check the car before the town clerk does

The town clerk checks paperwork, not the car's past. Run the VIN through NMVTIS for title brands, then a CARFAX or AutoCheck report for accidents and odometer history, especially on a pre-2000 car that doesn't carry a title. If the car has any damage history, read our New Hampshire salvage and rebuilt title rules before you pay.

A word on what we charge: CarVins is a licensed CARFAX and AutoCheck reseller, not affiliated with either brand or with any New Hampshire agency. As of late October 2026 our guest price was close to $5.50 a report, members paid near $4.50, and the two-report bundle was about $6.75, while buying direct runs around $39.99 to $44.99. The checkout page has the current number, so confirm it there before paying.
