Massachusetts Solar Property Tax Exemption

About This Program

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.
