Tax-exempt accounts

Tax exempt accounts that wish to maintain their tax exempt status in Nantucket PowerChoice must submit tax exemption documentation to the program’s electricity supplier.

This means that tax exemption documentation must be submitted each time the program’s electricity supplier changes.

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 National Grid already, but National Grid does not share this documentation with the program’s electricity supplier. It is the customer’s responsibility to submit this documentation.

Where to submit your forms

Please be sure to write your National Grid electricity account number(s) on all documentation submitted.
