New Hampshire allows cities and towns to offer an exemption from local property taxes for the assessed value of a solar energy system, electrical energy storage system, wind energy system, or wood-fired central heating system used on the property. A solar energy system is defined as a photovoltaic (PV) system or a system that "utilizes solar energy to heat or cool the interior of a building or to heat water for use in a building" and that includes one or more collectors and a storage container. Stoves and fireplaces do not qualify.
Cities and towns may adopt an exemption provision separately for each energy source. Visit the website above for a current list of cities and towns that offer this exemption. Contact your local tax collector or assessor for more information, and visit the Department of Revenue Administration's website for the most recent summary of cities and towns that offer an exemption by clicking here.
