Massachusetts law provides that solar-energy systems used as a primary or auxiliary power system for the purpose of heating or otherwise supplying the energy needs of taxable property are exempt from local property tax for a 20-year period.
This incentive applies only to the value added to a property by an eligible system, according to the Massachusetts Department of Energy Resources (DOER). It does not constitute an exemption for the full amount of the property tax bill.
When solar is utilized as a primary or auxiliary power system for an individual’s primary residence in the Commonwealth, the equipment directly related to that solar system is exempt from Massachusetts state sales tax.
Some local municipalities have rebates for solar PV systems. Check with your SunBug system designer to learn more.
