New Hampshire property tax records are public under the state’s Right to Know Law, RSA 91-A, and you look them up through the city or town where the property sits.1New Hampshire General Court. New Hampshire Code 91-A:4 – Minutes and Records Available for Public Inspection There is no statewide database. Every municipality keeps its own files, which means the search starts with knowing which town the property is in, then going to that town’s assessing department online or at the counter.2NH Department of Revenue Administration. Property Tax
What You Need Before You Search
Pull together at least one of three identifiers: the street address, the current owner’s name, or the Map and Lot number. The Map and Lot number is a parcel ID unique to each piece of land and gets you to the right record faster than anything else, especially in towns with repeating street names or owners who hold multiple properties. If you don’t know the parcel ID, municipal tax maps are open for public inspection during business hours by law, and most towns also post them online.3New Hampshire General Court. New Hampshire Code 31-95-a – Tax Maps
Searching Online
Most New Hampshire towns and cities contract with a vendor like Vision Government Solutions or Avitar Associates to host their property databases. Vision alone runs online lookups for dozens of New Hampshire municipalities, with data refreshed weekly or nightly.4Vision Government Solutions. New Hampshire Online Database The access point is almost always the town’s own website, under a heading like “Assessing” or “Property Lookup.” Enter the address, owner name, or parcel ID and the system returns a digital property record card you can view, download, or print for free.
Searching in Person
If the town has no online portal, or the record you want isn’t on it, go to the town hall during business hours and ask the assessor or municipal clerk. Inspection is free under RSA 91-A:4. If you want a photocopy, the town can charge the actual cost of producing it; New Hampshire courts have treated $0.50 per page as reasonable when overhead and equipment are factored in.1New Hampshire General Court. New Hampshire Code 91-A:4 – Minutes and Records Available for Public Inspection If the record isn’t ready on the spot, the office has five business days to produce it, deny the request, or explain in writing why more time is needed.
What’s on a Property Record Card
The main document is the property record card, sometimes called a CAMA card for Computer Assisted Mass Appraisal. One page covers a lot of ground.
The assessed value sits at the top. This is what the town thinks the property is worth for tax purposes, which is not necessarily what it would sell for; the gap can be wide in a fast-moving market or in the years between full revaluations.
The card also lists the property’s classification (residential, commercial, or another category), the annual tax owed, and any exemptions or credits applied to the account. Under RSA 72, credits for veterans and exemptions for qualifying elderly or disabled residents show up as deductions on the card. If you qualify for one and don’t see it, you have to apply through the local assessing department; nothing gets added automatically.5NH Department of Revenue Administration. Exemptions and Veterans Tax Credits
The physical description is where you want to look closely: square footage, number of rooms and bathrooms, year built, construction materials, and lot size. These are the inputs the assessor used to arrive at the valuation. A card that lists four bathrooms when there are two, or a finished basement that doesn’t exist, means the assessed value is sitting on bad data. Catching errors here is the first step toward fixing a bill.
Payment history (what’s been billed, paid, and anything outstanding with interest) typically lives on a separate screen or page maintained by the tax collector rather than the assessor.
Which Office Holds Which Records
Within each town, the work splits between two offices. The assessing department handles valuations: it decides what each property is worth, maintains the record cards, and updates files when buildings are added, demolished, or renovated. The tax collector handles money: billing, payments, delinquencies, and lien activity. For deed transfers and mortgages you go to the county Registry of Deeds, but for current assessed values and tax status, the municipal offices are the source.
The state Department of Revenue Administration oversees assessing practices across municipalities and reviews contracted revaluations, but it does not keep individual property records.2NH Department of Revenue Administration. Property Tax
How Current the Records Are
New Hampshire requires every municipality to update property values at least once every five years under RSA 75:8-a. These full revaluations, often called revals, pull assessed values back in line with market conditions town-wide. Between revals, assessors still update individual records for new construction, demolitions, discovered errors, or changes in use.
The timing matters when you’re reading a record. If the last reval was four years ago and your area’s prices have jumped, the number on the card may be well below current market value. If prices have cooled, it may be above. Towns that fall off the five-year cycle can be ordered by the DRA’s Property Bureau to revalue.
If the Record Looks Wrong
Property tax records are not just informational. When the assessed value is off, the record card becomes evidence in the formal challenge process known as abatement.
Filing an Abatement
You file in writing with the town’s selectmen or assessors. The deadline is March 1 after the tax notice date, provided the notice went out on or before December 31. If the notice was mailed later, you have two months from the mailing date.6New Hampshire General Court. New Hampshire Code 76:16 – By Selectmen or Assessors Miss the deadline and you’re out for the year.
The application has to spell out why the assessment is wrong. General complaints get nowhere. What works: comparable sale prices from similar properties in town, a recent independent appraisal, or documentation of physical conditions the assessor missed, such as structural damage, environmental contamination, or adverse easements. The town has until July 1 to respond in writing. Silence by that date counts as a denial.6New Hampshire General Court. New Hampshire Code 76:16 – By Selectmen or Assessors
Appealing a Denial
If the town denies the abatement or doesn’t respond, you can appeal to the state Board of Tax and Land Appeals (BTLA). When the tax notice was sent on or before December 31, the BTLA deadline is September 1, and you cannot file before the earlier of the town’s decision or July 1.7Board of Tax and Land Appeals. Property Tax You can also skip the BTLA and go straight to the superior court in your county, though that route tends to be slower and more expensive.
The burden is on you. The law presumes the assessor’s valuation is correct, and you need factual evidence to beat that presumption. The grounds must be specific enough that both the BTLA and the town know what you’re arguing; vague or conclusory filings can be dismissed.8Cornell Law Institute.

Delinquency Entries You May See
Unpaid taxes leave a paper trail on the record, which is why title searchers and prospective buyers pull these files before closing.
Interest starts at 8% per year from the due date on unpaid taxes.9New Hampshire General Court. New Hampshire Code 76:13 – Interest If the bill was mailed after November 2, interest holds off until 30 days after mailing. Once the tax collector executes a lien, the rate rises to 14%.10New Hampshire General Court. New Hampshire Code 80:69 – Redemption
A tax lien is a recorded claim that attaches to the land itself, not just the owner. Once recorded, the property cannot be sold or refinanced without satisfying it. You can redeem the lien any time before a deed issues by paying the full lien amount plus 14% interest from the execution date and any redemption costs. Partial payments are allowed and shrink the balance that interest runs on.
If a lien goes unredeemed for two years, the tax collector executes a tax deed transferring ownership of the property to the municipality.11New Hampshire General Court. New Hampshire Code 80:80 – Transfer of Tax Lien The former owner loses the property. The municipality can then sell it at public auction or by sealed bid on terms set locally. Lien execution dates, interest accrual, and deed transfers all appear in the tax records tied to that parcel.
What’s Shielded and What Isn’t
Social Security numbers and federal tax identification numbers submitted with abatement applications are confidential and exempt from disclosure.6New Hampshire General Court.
