From the desk
New Hampshire has no sales tax and wears it proudly on every border billboard. The desk's whole job on out-of-state deals is the reverse warning: Massachusetts and Maine buyers still owe use tax at home, no matter what the sticker celebrates.
Selling to an out-of-state buyer in New Hampshire
New Hampshire has no state sales tax on vehicle purchases.[2]
The tax answer is only half the job. The desk still has to move the title, issue the temp tag, and keep the deal from stalling while paperwork crosses state lines, and that chain is what Voltra's title tracking holds in one view.

Buying a car in a no-sales-tax state does not make it tax-free. Tax follows registration: register the vehicle in another state and that state's use tax is due there, at its rate. No sales tax is owed at registration in New Hampshire.[2]

Vehicle-type exceptions
No vehicle type pays sales tax in New Hampshire, so the type-specific issue here is titling, not tax. New Hampshire does not issue titles for vehicles of model year 1999 or older, which means an out-of-state buyer taking an older NH car home can end up with only a bill of sale and whatever prior title exists. Heavy trucks with three or more axles and truck-tractors over 18,000 lbs gross weight are always titled regardless of age. Older vehicles can be titled at the owner's request. On the registration side, RSA 261:153 sets a flat $5 town permit fee for farm tractors and for agricultural/industrial utility vehicles, and routes construction equipment to RSA 261:64.[6]
How New Hampshire actually levies this
New Hampshire collects nothing at the point of sale on a vehicle: no sales tax, no use tax, no title excise. The vehicle levy that does exist is the annual municipal permit fee, collected by the town or city clerk at registration under RSA 261:153, and it runs off the manufacturer's list price rather than what the buyer paid. The schedule is 18 mills per dollar of list price for a current model year vehicle, stepping down through 15, 12, 9 and 6 mills, and bottoming out at 3 mills for a vehicle five model years old or older, with a $5 floor. A state registration fee under RSA 261:141 and an $8 first-time plate fee are paid on top of it.[7]
