When is the deadline for filing tax abatement?

The application deadline is March 1st after the final tax bill of the year.  Per RSA 76:16, property owners who believe there is an error in their property assessment, or their assessment is disproportionate, may apply to the Board of Selectmen for an abatement.  Applications are available at the Assessing Office and on-line at: https://www.nh.gov/btla/forms/documents/abatement.pdf
