Tax Abatements for Property Owners

The New Hampshire Tax Abatement Process

In New Hampshire, the Department of Revenue Administration establishes an equalization ratio on an annual basis. To calculate what the municipality claims the property is worth in a given tax year, divide the total assessed value by the equalization ratio. Assessments are set on April 1 of each year, and appeals must be filed by March 1 of the following year.

Dates and procedures may vary from State to State.

There is no guarantee in the outcome of the tax abatement appeal, however, our firm only engages in cases that we are confident the outcome will be satisfactory to the client.

Remember that assessments are based on fee simple value, not on leased fee value.


  • April 1  Assessments are set
  • March 1  Deadline for filing your appeal
  • July 1  Municipality must respond if they are accepting your appeal
  • September 1  Deadline for you to file with BTLA or Superior Court
