New Hampshire Real Estate Tax Abatement Calendar and Key Dates

March 1. Deadline to file a written request with the municipality for an abatement of the prior year’s taxes (i.e., the tax year beginning the prior April 1).  Missed the March 1 deadline?  Give us a call, you still may have some options.

April 1.  The beginning of the tax year and the valuation date for all real estate for that particular tax year.

July 1.  Deadline for municipalities to grant (partially or fully) or deny an abatement request.  Failure of the municipality to take any action by this date shall be deemed a denial.  If the municipality grants a partial abatement, the taxpayer may request an appeal for the portion of the request not granted.

September 1.  Deadline to file an appeal of the municipality’s decision with either the Board of Tax and Land Appeals or Superior Court

November/December.  Months in which “final” tax bills generally are issued.  These bills show, for the first time, the assessed value of the real estate for that tax year.
