G. Phillip Blastos is the Commissioner of the New Hampshire Department of Revenue Administration with over 28 years experience in property taxes, sales tax, excise tax, property tax relief, and business taxes. The Department of Revenue is responsible for audits, collections, performs property appraisal, automates compliance, financial reports, tax research, litigation, estimates revenues for the state and oversees two major computer database systems in use by the Department of Revenue. The property tax is levied on the market value. Real and personal property is taxed by local taxing entities. In addition, local entities may levy three additional ad valorem taxes and the state government may levy three additional ad valorem taxes. Local entities may authorize eight different types of taxes instead of ad valorem property taxes. Some of the different types of taxes were created to reduce taxes on individuals as an economic development tool. Personal exemptions are for homeowners, renters, seniors, those with disabilities and veterans. Municipalities may grant exemptions for blind persons, solar, wind powered, and wood heating energy system exemptions. There is no personal property tax. Also exempt are cemeteries, and government, religious, charitable, and educational property. The Boston Area Service Center (ASC) provides tax service for New Hampshire.

How property tax determined

Residential property and land is assessed at 100% of market value and the assessor determines the fair market value. The assessor may use one of three methods.

  • Cost Approach

At current labor and material prices, estimate how much it would take to replace the property with one similar to it. Use this method when there are no sales of comparable properties.

  • Income Approach

For an apartment or office building, estimate how much income the property can produce.

  • Market Approach

Use other comparable properties that have sold recently, determine the most probable sales price of the subject property.

Appeal Procedure

  • First

Try to resolve the problem in an informal meeting with the tax assessor in the local county, after receiving an assessment notice.

  • Second

Next, if not satisfied with the informal meeting, file a formal appeal with the local mmunicipalitywithin two months after receiving the tax notice. The municipality has six months to deny or grant a taxpayer’s appeal.
