Tax-exempt accounts

Tax exempt accounts that wish to maintain their tax exempt status in Acton Power Choice 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.

Where to submit your forms

If you were enrolled in the program for any duration between September 2017 and September 2019, you were served by Dynegy and must submit tax-exemption documentation to Dynegy.
