Massachusetts Solar Property Tax Exemption

Massachusetts Legislature / City of Boston Assessing

Available Home Repair

About This Program

Massachusetts Solar Property Tax Exemption is available to homeowners in Boston, MA.

Massachusetts law exempts the added assessed value of a solar energy system from property taxes for 20 years from the date of installation. This means a Boston homeowner who installs solar panels worth $30,000 in added home value pays no additional property taxes on that value for 20 years. The exemption is automatic, no application is required. This stacks with the SMART program, solar tax credit, and any utility rebates.

No income limit. Automatic 20-year exemption on added property value from solar installation. Savings depend on system size, assessed value added, and local tax rate.
