New Hampshire Property Tax Law Changes 2026: What Homeowners Need to Know

Updated March 2026

Key Takeaway

New Hampshire has the 3rd highest effective property tax rate in the nation (2.18%) because it has no income tax and no sales tax -- property taxes fund nearly everything. The Elderly Exemption varies wildly by town ($5,000 to $175,000). File your abatement by March 1.

No Income Tax, No Sales Tax = High Property Taxes

New Hampshire's refusal to enact an income tax or general sales tax means property taxes carry nearly the entire burden of funding local services, schools, and county government. The average homeowner pays $5,951/year. This makes property tax appeals especially valuable in New Hampshire -- a 10% reduction saves nearly $600/year.

Town-Set Exemptions

New Hampshire lets each town set its own exemption amounts within state guidelines:

Elderly Exemption: Ranges from $5,000 to $175,000+ depending on the town (and age bracket: 65-74, 75-79, 80+)
Veteran exemption: Standard $50 credit, but towns can vote for up to $500
Disabled exemption: Towns set their own amounts

Check your specific town's exemption schedule -- the variation is extreme.

5-Year Revaluation Cycle

New Hampshire requires municipalities to conduct a full revaluation every 5 years (with annual updates between cycles). Revaluation years often bring the largest assessment changes. If your town is in a revaluation year, pay close attention to the new values and appeal if they exceed market value.

Abatement Process

New Hampshire uses the term "abatement" for property tax appeals. File an application with your municipality's Board of Selectmen by March 1. If denied, appeal to the Board of Tax and Land Appeals (BTLA) or Superior Court within 2 months.

Property Tax Deferral

New Hampshire allows property tax deferral for homeowners experiencing hardship due to disability, inability to pay, or when taxes are disproportionate to income. The deferred taxes become a lien on the property. Apply through your town's governing body.
