How New Hampshire property taxes work

How is a property tax bill calculated?

The bill is the assessed value multiplied by a tax rate expressed per $1,000 of value. The rate combines several parts—municipal, local school, state education and county—and is set each year with oversight from the NH Department of Revenue Administration.

Because towns raise their own budgets and have different tax bases, two homes with the same market value in different towns can have quite different bills. It is the most common surprise for buyers moving from a state with a broad income tax. See current town rates on our New Hampshire property tax page.

Why isn’t the assessed value the same as market value?

Towns update assessments on a cycle rather than continuously, so an assessed value can lag the market. The Department of Revenue Administration publishes equalization ratios that put towns on a common footing. When you compare towns, compare equalized figures—or better, the actual dollar bill—rather than two raw rates.

A low rate on a high assessment and a high rate on a low assessment can produce the same bill. Compare the dollar amount for a specific property.

How do I check the taxes on a specific home?

• Ask the listing agent for the most recent tax bill, not an estimate.
• Confirm the current rate and the assessment year with the town’s assessing office.
• Ask whether a revaluation is underway or scheduled—it can change your bill after you buy.
• Ask whether any exemptions or credits on the current bill belong to the seller and will not carry over to you.
• Ask about village district taxes or special assessments that appear on some bills.
• Run the numbers with the property tax calculator, then compare two towns.

Are there exemptions, credits or appeals?

New Hampshire lets towns offer exemptions and credits—for example for qualifying veterans, elderly residents, people who are blind and certain improvements—with eligibility rules and, in several cases, amounts adopted locally. Check with the town where you are buying rather than assuming what applied where you live now.

If you believe an assessment is wrong, you can apply to the town for an abatement, with further appeal routes beyond it. Deadlines are strict; confirm current dates with the town and the Department of Revenue Administration.

How should I budget for property taxes?

Treat property tax as a monthly cost alongside principal, interest and insurance. It is often what makes two towns comparable—or puts one out of range. If your lender escrows taxes, ask for the escrow to be quoted from the actual current bill. Our cost of living guide puts taxes alongside heating, driving and utilities.
