2

No statewide homestead exemption — check your municipality for local exemptions

3

Board of Tax and Land Appeals (BTLA) is the state-level appeal body

Appeal Deadline

March 1 following the FINAL tax bill (abatement to the municipality); BTLA or Superior Court — not both — by September 1

The March 1 clock runs from the final tax bill, which in semiannual towns is the second bill, not the first. The municipality must act by July 1; silence counts as a denial. You then choose the BTLA or Superior Court by September 1 — they are mutually exclusive, so picking one forecloses the other. If notice of the tax is issued after December 31, RSA 76:16-d substitutes a 2-month abatement window and 6- and 8-month appeal windows instead.

Understanding New Hampshire's Assessment Ratio

100%
100% of full and true value

New Hampshire assesses at 100% of market value, so your assessed value should equal what your property is worth on the open market.

This makes appeals straightforward: if comparable homes in your area sold for less than your assessed value, you have grounds for an appeal.

New Hampshire's assessment ratio study

How closely New Hampshire assessors' values actually track real sale prices — and whether you can use that in an appeal.

Applied directly in appealsLatest study: 2025

Equalization Reports / Assessment-to-Sales Ratio Study

Divide your assessment by the property's true market value and compare to the town's DRA-certified median equalization ratio — if yours is higher, the assessment is disproportionate and the excess is abated under RSA 76:16, or on appeal to the BTLA or superior court.

Supplemental, Escape & Corrected Bills in New Hampshire

New Hampshire has no supplemental or prorated property tax bill - everything keys off the April 1 assessment date. Distinct extra bills homeowners may see are the one-time Land Use Change Tax when current-use land is developed, and corrected bills for omitted/improper assessments; both are contested via the abatement process (apply by March 1 after the final tax notice, appeal to BTLA/Superior Court by September 1).

Corrected/After-Assessed Taxes for Omissions or Improper Assessment

Selectmen/assessors discover property omitted from assessment or improperly assessed; they may assess the omitted tax (RSA 76:14 allows correction where taxes were omitted or improperly assessed).

Appeal window: Standard abatement route: written abatement application to the municipality by March 1 following the final notice of tax (or 2 months after notice if the notice came after Dec 31); municipality decides by July 1; appeal to BTLA or Superior Court by September 1 following the notice of tax.

Land Use Change Tax (LUCT)

Land in current-use (open space) assessment is changed to a non-qualifying use; a one-time tax of 10% of the land's full and true value (without regard to current-use value) is billed separately.

Appeal window: Each LUCT bill requires its own abatement request to the municipality within 2 months of the notice of tax; if refused/ignored, appeal to the BTLA or Superior Court (BTLA appeal generally due by the statutory date following the notice - see RSA 79-A:10).
