Property Tax Appeals · New Hampshire
Appeal your property taxes
in New Hampshire.
New Hampshire funds local government almost entirely through property taxes — no broad income or sales tax — so the stakes per assessment dollar are among the highest anywhere. Relief runs through abatement: a written application to your town’s assessing officials (selectmen or assessors) by March 1 after the final tax bill. The town rules on it; if it denies you or fails to act, you appeal to the state Board of Tax and Land Appeals or superior court by September 1. Values are set as of April 1, and towns assess at varying ratios of market value, so the case is made by comparing your assessment — through the town’s equalization ratio — against real market evidence.
The abatement application is due to your municipality by March 1 following the final tax bill — statewide. Appeals to the BTLA or superior court follow by September 1 if the town denies you.
Because towns assess at different percentages of market value, a fair-looking assessment can still be too high once you apply the equalization ratio. A licensed appraisal as of April 1 nails down the market-value side of that equation — the half the town can’t argue with a spreadsheet.
The evidence
Boards act on value,
not frustration.
However New Hampshire labels the process, the case underneath is identical: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal — comparable sales, documented adjustments, a signed opinion of value — is that showing. Start with the $5 check to see if the numbers are on your side before you spend real money.
- Valued as of your assessment date — not today
- Comparable sales with adjustments and citations
- Signed by a state-licensed NH appraiser
- Phone walkthrough — no stranger in your home

New Hampshire questions
March 1 following the date of the final tax bill — the application goes to your municipality’s assessing officials. If denied, you have until September 1 to appeal to the BTLA or superior court.
The Board of Tax and Land Appeals — the state body that hears abatement appeals after a town denies one. It’s less formal than court and weighs market-value evidence like comparable sales as of April 1.
With no broad income or sales tax, property taxes carry most of the load for schools and towns. That’s exactly why an over-assessment costs more here than almost anywhere — and why checking it is worth the effort.
