If there is no sales tax, what do I pay at registration?

You pay an annual municipal permit fee to your town or city, calculated from the manufacturer's original list price using the RSA 261:153 mill schedule, plus a small state registration and agent fee. The newer the car, the higher the permit fee.

How is the municipal permit fee calculated?

The town fee is a mill rate per $1,000 of the manufacturer's list price that steps down with the vehicle's age: 18 mills in the current model year, 15, 12, 9, 6, then 3 mills for cars five years or older. So a $30,000 list-price new car costs about $540 in town fees.

Does buying out of state help me avoid New Hampshire fees?

No. If you are a New Hampshire resident registering the car here, you still pay your town's municipal permit fee and state registration fees regardless of where you bought it. The benefit of New Hampshire is that there is no sales tax to add.

Does this include title and inspection costs?

No. This estimates the sales tax (zero) and the municipal permit plus state registration fees. New Hampshire title fees, plate fees, and the required annual safety and emissions inspection are separate costs you pay on top.

New Hampshire is one of five U.S. states with no general sales tax, and that exemption covers vehicles too — the car sales tax rate in New Hampshire is 0%. What you actually pay at registration is the annual municipal permit fee your town charges, plus small state fees. This tool confirms the zero sales tax and estimates that permit fee.

How it works

There is no sales or use tax line — the calculation is simply:

sales tax = purchase price × 0% = $0

The municipal permit fee follows New Hampshire RSA 261:153, a mill rate applied to the manufacturer’s original list price (not what you paid), stepping down as the car ages:

permit fee = (list price / 1000) × mills
mills = 18 (new) → 15 → 12 → 9 → 6 → 3 (5+ years old)

A small flat state registration and agent fee is added on top.

Example and notes

A brand-new car with a $30,000 manufacturer’s list price is in its current model year, so the mill rate is 18: the town permit fee is 30,000 / 1,000 × 18 = $540, plus the state fee — and $0 in sales tax. Towns add minor clerk, plate, and title fees and may set minimums, so confirm the exact figure with your town or city clerk. The headline takeaway stands: New Hampshire adds no sales tax to a vehicle purchase.
