Important Information about tax exemption refunds

As a result of continued system improvements, DTE Energy will not be able to process tax exemption refunds between Jan. 23, 2017, and April 3, 2017. We will begin processing refunds on April 4, 2017; refunds may take up to 90 days to process. We apologize for any inconvenience this may cause, and we appreciate your patience as we work diligently to complete these improvements.

All gas and electric business accounts are required to submit a copy of the Michigan General Sales Tax Exemption form to DTE Energy in order to have the correct tax exemption status on file and be billed accordingly.

A letter on company letterhead identifying the DTE account number, meter number and period of time the refund is being requested.
A completed Certificate for Exemption from Michigan General Sales Tax that has the following dates:
Date Issued – this is the start date of the refund requested.

If you are acting on behalf of a DTE electric or gas customer, DTE requires that a Customer Release Authorization form is completed by the DTE customer. Please complete all of the required areas and send the authorization form along with the documents listed above to DTE either by mail, fax or email as stated above. Please only use one method of communication.
