New Hampshire charges no sales tax on vehicles — none at state level, none locally. Alongside Montana, it's the cleanest 'the price is the price' state in the country: your out-the-door number is the negotiated price plus title, registration, and the dealer's doc fee, full stop.
Doc fees are uncapped, typically $300–450 — and with no tax line to hide behind, they're the main soft spot on a New Hampshire buyer's order. The registration side carries the state's real recurring charge: town-level registration includes a value- and age-based component that starts around $18 per $1,000 of list value in year one, declining as the vehicle ages — a few hundred dollars annually on a newer car, dropping steadily.
One cross-border reality check, since half the state shops the Massachusetts market: the tax follows the buyer, not the lot. A New Hampshire resident buying in Massachusetts titles at home tax-free (dealers handle the paperwork routinely), while a Massachusetts resident buying in New Hampshire still owes Massachusetts its 6.25% at registration. The border saves New Hampshirites nothing extra — the savings were already theirs — and saves Bay Staters nothing at all.
Every figure above was last verified against official New Hampshire sources in August 2026. Tax rules do change — the final word is always your paperwork and the DMV.
