How is New Hampshire property tax calculated?

Property tax equals your assessed value divided by 1,000, multiplied by your town's total tax rate. New Hampshire towns publish a combined rate per $1,000 that bundles the municipal, county, local school, and state education portions into one number.

Why are New Hampshire property taxes so high?

Because New Hampshire has no broad sales or income tax, local government and schools are funded largely through property taxes. The state's effective property tax rate is among the highest in the country, often near 2 percent of value.

What is the difference between assessed and market value?

Market value is what a buyer would pay; assessed value is the figure your town's assessor places on the property for tax purposes. Towns periodically revalue, and an equalization ratio adjusts assessments toward market value across the state.

Does New Hampshire offer property tax relief?

Yes. New Hampshire offers a low and moderate income homeowners property tax relief program, plus elderly, disabled, veteran, and blind exemptions that vary by town. These reduce taxable value or rebate part of the bill but are not modeled here.

What rate should I use if I don't know my town's?

Town rates vary widely, from roughly $10 to over $30 per $1,000. The statewide average total rate is in the low-to-mid $20s per $1,000. Use your exact town rate from your tax bill for an accurate result.

New Hampshire funds most local government through property taxes because it has no general sales or income tax. That makes its effective property tax rate one of the highest in the nation. This estimator multiplies your assessed value by your town’s combined rate per $1,000 to project the annual bill.

How it works

Every New Hampshire town sets one combined rate per $1,000 of assessed value:

Annual tax = (assessed value ÷ 1,000) × total town rate
Effective rate = total rate ÷ 1,000 × 100%

The town rate bundles four components — municipal, county, local school, and the state education tax — into a single number. Higher assessed value or a higher town rate raises the bill linearly. Optional exemptions for elderly, disabled, or veteran homeowners reduce the taxable value before the rate is applied.

Example

A home assessed at $400,000 in a town with a total rate of $22.50 per $1,000 owes (400,000 ÷ 1,000) × 22.50 = $9,000 a year. That is an effective rate of 2.25 percent of assessed value.

Notes

Use your assessed value from the town tax card, not the market price, and your town’s published total rate, which changes annually after the state sets it. Available exemptions and the low and moderate income relief program can lower the amount owed and are not included here. Verify rates with your town’s assessing office and the New Hampshire Department of Revenue Administration.
