NEW HAMPSHIRE PROPERTY TAX & EQUALIZATION FAQ

STATUTORY REFERENCE
What is the statutory deadline to appeal property taxes in New Hampshire? +
The resolved statutory filing deadline for New Hampshire is March 1, 2027 (to local selectmen/assessors). Initial local reviews are filed with the Local Board of Selectmen / Assessors (Abatement), with administrative escalation to the New Hampshire Board of Tax and Land Appeals (BTLA) / Superior Court.
How is residential property assessed in New Hampshire? +
Under New Hampshire law, residential real property is assessed at 100% of fair market value (and commercial property at 100%). Equal and uniform taxation across properties is protected under N.H. Const. pt. II, art. 5 ("To impose and levy proportional and reasonable assessments, rates, and taxes").
How does Truth-in-Taxation work during New Hampshire county reappraisals? +
Under RSA § 21-J:9-a (Department of Revenue Administration municipal equalization ratios), when a county completes a reappraisal cycle (Every 5 years by municipal revaluation mandate (N.H. Const. pt. 2, art. 6)), the taxing authority must calculate a certified revenue-neutral tax rate so the reappraisal itself does not automatically create an unadvertised windfall tax increase.
