What actually sets New Hampshire apart
New Hampshire levies no general income tax and no sales tax, so property tax carries almost the whole load. That is why the effective rate is among the highest in the country, and why comparing a New Hampshire bill against a Massachusetts one in isolation is misleading: you have to weigh the income and sales tax you are not paying.

Rate and bill agree in New Hampshire
New Hampshire sits 4th of the fifty by tax rate and 3rd by the amount a median-value owner actually pays. That agreement is less common than it sounds: 19 of the 50 states move ten places or more between the two rankings, because home values vary far more widely than rates do. In New Hampshire the 1.77% headline is a fair summary rather than a figure that needs correcting.
How New Hampshire works out what you owe
Municipalities assess at market value and must revalue at least every five years. The bill combines town, county, local school and a statewide education tax.
New Hampshire sets no statutory limit on how fast a home's taxable value can rise, so a New Hampshire assessment tracks the market more closely than it would in a capped state.
Exemptions New Hampshire homeowners should claim
Each of these reduces a New Hampshire bill every year you hold the property, and almost none are granted without a claim:
- Elderly exemption: Towns adopt their own elderly exemption amounts and income and asset limits by vote, so the relief available differs sharply from one town to the next.
- Veterans' tax credit: A credit applied directly against the bill for qualifying veterans, with a larger credit for service-connected total disability. The amount is again set locally.
Where you buy inside New Hampshire changes the bill
A statewide average hides its extremes. Where they show up in New Hampshire:
- Hillsborough County: Manchester and Nashua, where the southern-tier towns compete directly with Massachusetts on total cost
- Rockingham County: the seacoast and the Massachusetts border towns, with the state's highest values
- Merrimack County: Concord and the centre of the state, with rates that vary widely between adjoining towns
New Hampshire and its neighbours
The same $367,200 — the New Hampshire median — taxed at each neighbouring state's average rate:
- Maine at 1.1%: about $4,039 a year, roughly $2,466 less than the $6,505 a New Hampshire owner would pay on the same value.
- Vermont at 1.71%: about $6,279 a year, roughly $226 less than the $6,505 a New Hampshire owner would pay on the same value.
- Massachusetts at 1.11%: about $4,076 a year, roughly $2,429 less than the $6,505 a New Hampshire owner would pay on the same value.
Appealing a New Hampshire assessment
If the assessed value on your New Hampshire home overstates what it is worth, the route is an appeal to the town for abatement, then the Board of Tax and Land Appeals or Superior Court. The window is abatement requests are due by 1 March following the final bill, and it is strict — missing it means waiting a full cycle.
Frequently asked questions
When are New Hampshire property taxes due, and when must exemption claims be filed?
Most towns bill semi-annually, with an estimated bill due 1 July and the final, reconciled bill due in December. Applications are filed with the town selectmen or assessor by 15 April for that tax year.
Does this calculator use my exact New Hampshire county tax rate?
No — it applies the New Hampshire statewide average of 1.77%. Rates are set locally, and the spread inside New Hampshire is wide enough to matter: on a $367,200 home, $2,880 a year separates New Hampshire from an averagely taxed state before any county variation is counted. Check the parcel's own rate with its New Hampshire county before relying on this figure.

How this estimate is built
Principal and interest come from the standard amortization formula, worked through in full on the formula reference page. Property tax, insurance, PMI and loan-program figures layer on top from published assumptions — each one sourced, dated and listed on the methodology page. Every result here is an estimate built from public data, not a quote: confirm the specifics with a lender before relying on it.
