How to get an EIN in Indiana: step by step

  1. Form your business entity first. Your Indianan LLC, corporation, or other entity must exist before applying for an EIN. Form an LLC in Indiana or form a corporation if needed.
  2. Pick your responsible party. The IRS requires one individual with substantial control over the entity (typically an owner with at least 25% interest) to be listed on Form SS-4.
  3. Apply online at irs.gov. US founders with a valid SSN or ITIN get the EIN immediately. The application is free and takes about 10 minutes.
  4. International founders: apply by fax or mail. Without an SSN or ITIN, the online system will not work. Fax Form SS-4 (typically 4 business days) or mail it (4 to 6 weeks). ITIN vs EIN explained.
  5. Register with the Indiana Department of Revenue. Use the BT-1 Business Tax Application to get your state-level tax accounts in Indiana.
