Tax-exempt accounts

Tax exempt accounts that wish to maintain their tax exempt status in Lexington’s Community Choice Program must submit tax exemption documentation to the program’s electricity supplier.

The program’s electricity supplier is required by the State of Massachusetts to have valid tax exemption documentation on hand for all tax exempt accounts.

You may have submitted tax exemption documentation to Eversource already, but Eversource does not share this documentation with the program’s electricity supplier. It is the customer’s responsibility to submit this documentation.

Tax exemption documentation must be submitted each time the program’s electricity supplier changes.

The current electricity supplier for Lexington’s Community Choice Program is Constellation.

Where to submit your forms

Please be sure to write your Eversource electricity account number on all documentation submitted.

  • Send to Constellation via email at or via fax at 877-243-4968
  • Send a copy to the Town’s program consultants via email at or via US mail at MassPowerChoice, ATTN: Tax exemption documentation, 85 Merrimac Street, 3rd Floor, Boston, MA  02114
