How do I obtain a utility sales tax exemption?

Utility sales tax on items such as telephone, gas, electric, or water that is used to further an organizations' exempt purpose may be exempt from utliity sales tax.

To apply for a utility sales tax exemption, complete the ST-200 form.

In some circumstances, a complete utility study must accompany the ST-200 form.

Once the ST-200 form is approved by the Indiana Department of Revenue (DOR), an ST-109 or blanket certificate will be issued in the legal entity name as registered in DOR's system.
