A New Hampshire dealer may issue a 20-day temporary plate on any vehicle it sells - RSA 261:56 is not written as resident-only - so an out-of-state buyer normally drives home on the dealer's 20-day plate and titles and registers at home inside that window.

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]
