Michigan General Sales Tax Exemption Information

Important Information about tax exemption refunds

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. If you would like more information about tax exemptions, visit the State of Michigan Department of Treasury website

Download a copy of the Michigan General Sales Tax Exemption form and return it to: sysctrl_tax_exempt@dteenergy.com.

Please make sure to complete the form entirely and include all documentation with your request. We require one form per account.

If you discover that your account should have been tax exempt, you may be entitled to a credit on your DTE account. DTE is only allowed to credit taxes paid for a period of up to 4 years. In order to process a tax credit, DTE requires the following documentation:

  • 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.
    • Section 4 Certification Date – the date the form was signed.

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.
