New Hampshire property taxes
New Hampshire property tax calculator
Choose a town and enter the town’s assessed value for the property — not the purchase price. New Hampshire property tax is charged on assessed value. This estimate uses the town’s 2025 rate before exemptions, credits and any separate district charges.
Where to find the assessed value: it is printed on your property tax bill, and every New Hampshire town publishes its assessment records through the town assessing office — most have an online property lookup. Use the current assessed value from the municipality. Purchase price and assessment can differ in either direction; one is not a substitute for the other.
Rates shown are the 2025 New Hampshire tax rates set by the New Hampshire Department of Revenue Administration (source). Enter the town’s assessed value, not a purchase price or market value. Towns set a new rate each year and reassess on their own schedule, so a future bill may differ; exemptions, credits and separate district charges are not included.
How this is calculated
New Hampshire tax rates are quoted per $1,000 of assessed value, so the calculation is assessed value ÷ 1,000 × rate. The multiplication is straightforward, but the final tax bill can change with the applicable tax district, exemptions, credits, adjustments and tax year.
A purchase price is not an assessed value. Revaluations and property changes can alter assessments, and the relationship between assessed and market value varies. A townwide equalization ratio is not a property-specific appraisal. Ask the assessing office about the current parcel record and pending changes rather than converting an asking price into a promised bill.
Full rate detail by town, including each rate’s municipal, county, state education and local education components, is on the New Hampshire property tax rate guide.
