I have posted a few times recently regarding the Elderly Tax exemption laws in NH.  The rules are determined on a town by town basis though they all follow similar guidelines and can change from time to time.  As the state of NH has no income or sales tax the state, county and town budgets must be supported by property taxes.  In order to relieve the tax burden on the elderly, towns will put exemptions in place.

The most common similarities seem to be that the benefits start at age 65 and to be eligible the homeowner must have been a resident for at least 3 years.  Once an eligible homeowner reaches 65 they can apply for the exemption.  Usuallly their application must be submitted to the town before April 1st.

The age range for benefits has three tiers.  The first is 65-74, then 75-79 and finally 80+.  The towns of Windham and Pelham offer full tax exemption for those over 80 years of age.

There are also income limitations as well as asset limitations.  These too vary on a town by town basis.  The highest income limits as well as asset limits are in Litchfield.  I have assembled some of the more relevant information below.  This information is accurate to the best of my knowledge but before making a final decision on what benefit works for you please follow up with the town or visit their website.
