Frequently asked questions
How much is sales tax on a car in New Hampshire?
New Hampshire has no general state sales tax on vehicle purchases, so the state sales tax is $0. Some local taxes or state-specific fees can still apply — see the notes below and confirm with New Hampshire Division of Motor Vehicles.
Do I pay sales tax when buying a used car from a private seller in New Hampshire?
In most states, sales or use tax on a private-party vehicle purchase is collected when you title and register the car, not at the point of sale. The rate is generally the same as a dealer sale. Confirm the private-sale rules with New Hampshire Division of Motor Vehicles.
Does New Hampshire give a sales tax credit for a trade-in?
Most states tax only the difference between the vehicle price and your trade-in value, which lowers the tax you owe. A handful of states tax the full price with no trade-in credit. Verify New Hampshire's treatment before you rely on the estimate above.
Are there local or county car sales taxes in New Hampshire?
Often, yes. The rate shown here is the New Hampshire state rate only; many counties, cities, and transit districts add a local sales tax on vehicle purchases, so your combined rate can be higher. New Hampshire Division of Motor Vehicles publishes the official combined rates.
Can you legally avoid sales tax on a used car in New Hampshire?
The legitimate ways to lower or avoid vehicle sales/use tax in New Hampshire are a qualifying trade-in credit (where the state allows one), a genuine gift or qualifying family transfer, or a specific exemption the state grants — not understating the sale price, which is illegal and easily caught by New Hampshire Division of Motor Vehicles against the vehicle's fair-market value. Confirm any exemption with New Hampshire Division of Motor Vehicles before relying on it.
