How do I obtain a utility sales tax exemption?


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.
