What will I see on my bill?
DTE Energy Supply will be identified as your SCO supplier on your bill.
I am a business customer and exempt from sales tax due to the nature of my business. What do I need to do to eliminate sales tax charges from my bill?
In order for us to stop charging you sales tax OR continue your tax exempt status, you need to provide DTE Energy Supply with a sales tax exemption certificate (PDF). DTE Energy Supply is required by the state of Ohio to have a copy of your tax exemption certificate on file. Therefore all qualifying tax exempt customers are required to provide us with a sales tax exemption certificate within 60 days of initial service. If we do not have a tax exemption certificate in our file 60 days from initial delivery, we will be required to discontinue your tax exempt status.
Please complete the form and send it to:
DTE Energy Supply
Ohio Gas SCO Customer Service
414 South Main Street, Suite 200
Ann Arbor, MI 48104
Alternatively, you can e-mail a scanned copy to DTESupply@dteenergy.com or fax it to 734.887.4065. Please be sure to include your name, utility company, account number and phone number in the e-mail/fax cover sheet in case we have follow-up questions.
Once received by us, future bills will reflect your tax exemption. Refunds on sales tax already paid can be claimed from the Ohio Department of Taxation.
