New Hampshire Property Tax Appeal — Key Facts
How to Appeal in New Hampshire
Check your assessment notice
Your county assessor mails assessment notices — usually in spring. The notice shows your assessed value and the appeal deadline. In most states you have 30–90 days from the notice date.
Gather comparable sales
Find 3–5 similar properties in your neighborhood that sold recently at prices below your assessed value. Use Zillow, Redfin, or your county recorder's public records. The more recent and similar the sales, the stronger your case.
File your formal appeal
In New Hampshire, you file with the Municipal Assessor, then Board of Tax and Land Appeals. File abatement application with your town/city assessor by September 1. If denied, appeal to the NH Board of Tax and Land Appeals (BTLA) by March 1 of the following year. File before September 1 (Abatement application to Assessor).
Present your evidence at the hearing
Show up with your comparables. Be calm and factual. You don't need a lawyer. Appeals boards are accustomed to homeowners representing themselves. Simply demonstrating that comparable properties sold for less than your assessment is often enough to win a reduction.
Expert tip for New Hampshire
New Hampshire has no income or sales tax — property taxes fund nearly everything, making over-assessments especially costly. The BTLA process is thorough but effective.
