New Hampshire Property Tax Calculator 2026

This New Hampshire property tax calculator is a free, browser-based tool that turns a home value into an annual and monthly tax bill using the 2.18% statewide effective rate, or any town rate you enter. New Hampshire bills at the municipal level, so a $355,000 home costs about $7,739 a year — roughly $645 a month in escrow.

How New Hampshire Property Tax Works

Property tax in New Hampshire is an annual tax levied on real estate by local governments — primarily counties, municipalities, and school districts. The amount you owe is determined by your property's assessed value multiplied by the local mill rate. The statewide effective rate is approximately 2.18% of market value, placing New Hampshire 1.08% above the national average of 1.10%.

The effective rate combines all local levies: county tax, municipal tax, school district tax, and any special assessments. Because New Hampshire has multiple taxing jurisdictions, your actual rate depends heavily on where in the state your property is located. The 2.18% figure is a weighted average across all New Hampshire counties.

On the median New Hampshire home valued at $355,000, the typical annual property tax bill is about $7,739 — or roughly $645 per month when paid through a mortgage escrow account.

Who Collects Property Tax in New Hampshire — and How Rates Are Set

New Hampshire is one of the few states where property tax is assessed and collected almost entirely at the municipal level, not the county. Each of the state's 234 cities and towns runs its own assessing office, sets its own tax rate, and issues its own bill. The county levy exists, but it is billed to you through your town — you never deal with a county assessor. That is why two neighbouring New Hampshire towns can differ by several dollars per $1,000 of assessed value.

Mill rates (expressed as dollars of tax per $1,000 of assessed value) are set annually based on local budget needs. A mill rate of 10 equals a 1.0% effective rate. Most jurisdictions reassess properties every one to four years, though some reassess annually. If your home's market value rises faster than neighboring properties, your share of the tax burden can increase even if the mill rate stays the same.

To find your exact rate, contact your town or city assessing office — not the county. Your New Hampshire tax bill breaks the rate into four separate lines: municipal, local school, state education (SWEPT), and county. Add those four together and enter the total in the Local Tax Rate field above; the calculator then replaces the 2.18% statewide average with your real number.

New Hampshire Property Tax Exemptions and Relief Programs

New Hampshire does not have a general homestead exemption for property tax — a common and expensive misconception. What it has instead is a set of locally-adopted programs: the elderly exemption under RSA 72:39-a (age 65+, three consecutive years' residency before 1 April), a veterans' tax credit, exemptions for the blind and for the disabled, and the statewide Low & Moderate Income Homeowners Property Tax Relief claim.

Veterans may qualify for a partial or full exemption depending on disability rating and service history. Agricultural land often receives a preferential assessment based on use-value rather than market value. If you believe your assessment is incorrect, you have the right to appeal — typically within 30 to 90 days of receiving your assessment notice.

Apply through your town or city assessing office on state Form PA-29, generally by 15 April. The detail that trips people up: the statute sets only a floor, and each of the 234 municipalities adopts its own income limit, asset limit, and exemption amount above that floor. Exemption values commonly run from $50,000 to well over $200,000 off assessed value depending on the town, so never assume a neighbouring town's published figures apply to yours — check locally, every year.

Why New Hampshire's Property Tax Rate Is the Highest in New England

New Hampshire levies no broad-based income tax and no general sales tax. That revenue has to come from somewhere, and it comes almost entirely from property. The result is a 2.18% statewide effective rate against a 1.10% national average — but it is not a straight loss. A household earning $120,000 pays roughly $0 in state income tax here versus several thousand dollars in Maine, Vermont or Massachusetts, which is why the honest comparison is total state and local burden, not the property line alone.

One line on your bill is state-level: the Statewide Education Property Tax (SWEPT), levied under RSA 76:3 and collected by your town on the state's behalf to fund an adequate education. It is included in the combined rate you enter above, so do not add it a second time. Full rate tables and the Form PA-29 exemption application are published by the New Hampshire Department of Revenue Administration, which certifies every municipality's tax rate each autumn before bills go out.

How to Appeal a New Hampshire Property Tax Assessment

New Hampshire runs an abatement process with hard statutory dates, and missing one costs you the whole year. Under RSA 76:16 you file an abatement application with your town or city — not the county — by 1 March following the final tax bill. The municipality then has until 1 July to grant, deny, or say nothing; silence counts as a denial. From there you appeal to either the NH Board of Tax and Land Appeals or the superior court — one or the other, never both — by 1 September.

The Equalization Ratio Trap

Before you claim you are over-assessed, apply your town's equalization ratio. Assessed values drift below market between revaluations, and the Department of Revenue Administration publishes a ratio each year showing how far. If your town's ratio is 85%, a house genuinely worth $400,000 should be assessed near $340,000 — so an assessment of $350,000 is only about 3% high, not 13%, and an abatement is unlikely to succeed. Comparing your raw assessment with a recent sale price and skipping the ratio is the single most common reason NH abatement claims fail.

What Happens If You Miss a New Hampshire Property Tax Bill

New Hampshire towns bill property tax twice a year, and an unpaid bill does not simply sit as a debt: interest starts the day after the due date, and after a statutory notice period the town records a tax lien against the property. From the date the lien is executed the owner has a redemption window of two years before the municipality can issue a tax deed and take title outright, which is why a small unpaid balance can end in the loss of the home rather than a collection lawsuit. Redemption costs the unpaid tax plus interest and the lien and deeding fees, so paying during the interest-only stage is far cheaper than redeeming later. If you cannot pay, ask the town about an abatement, a hardship deferral for elderly or disabled owners, or a payment arrangement before the lien executes, since options narrow sharply afterwards. The Department of Revenue Administration publishes the process at revenue.nh.gov. Updated September 2026.

Tips to Manage Your New Hampshire Property Tax Bill

First, verify your assessment is accurate. Review your property record card at your town assessing office and check for errors in square footage, bedroom/bathroom count, or lot size. Even small errors can inflate your assessed value and tax bill. If the assessment seems high, look up recent sale prices of comparable homes in your neighborhood and file an appeal if warranted.

Second, apply for every exemption you qualify for. Homestead, senior, veteran, and disability exemptions can reduce your taxable value by thousands of dollars. Third, if your mortgage servicer handles tax payments through escrow, review your escrow statement annually. Servicers sometimes over-estimate and hold excess funds — you may be entitled to a refund. Finally, New Hampshire property taxes are due July 1 and December 1.

Appealing a New Hampshire Property Tax Assessment

New Hampshire has no income or sales tax, which is exactly why its property tax carries so much weight — and why an over-assessment is worth challenging. The route is an abatement application to your town or city’s board of selectmen or assessors, filed after the final tax bill for the year is issued, with an appeal to the state Board of Tax and Land Appeals or the Superior Court if the town denies it. Two points decide most cases. You must argue that the assessed value is wrong, not that the tax bill is too high: the rate is set by the budget and is not appealable. And you must account for the town’s equalisation ratio, because assessments often sit deliberately below or above full market value — comparing your assessment straight against a recent sale price without adjusting for that ratio is the most common reason an otherwise sound abatement fails. Bring three comparable sales, not one. Source: New Hampshire Department of Revenue Administration. Updated 2026-09-18.
