State vs Federal
Is an Indiana EIN Different From a Federal EIN?
No. An Indiana EIN is the same as a federal EIN, because the IRS is the only authority that issues EINs. The number works in all 50 states. Indiana does not issue its own EIN. You apply once and use the same 9-digit number nationwide.
Indiana businesses confuse two separate numbers. The federal EIN comes from the IRS for federal taxes. The Indiana state tax ID comes from the Indiana Department of Revenue for state taxes. You may need both.
| Number | Issuer | Purpose | Cost |
|---|---|---|---|
| Federal EIN | IRS | Federal taxes, banking, Form SS-4 | $0 (IRS) |
| Indiana state tax ID | Department of Revenue | State income tax, sales tax | Registration via INBiz |
Your EIN does not replace state tax registration. Register with the Indiana Department of Revenue when you have employees, collect Indiana sales tax, or owe state withholding. See our state tax ID guide for the distinction. The federal EIN cost is always $0 from the IRS.
How to Apply
How Do You Get an EIN in Indiana?
You get an EIN in Indiana through the IRS, not the state. Four methods exist. Residents with an SSN apply online for an instant number. Non-residents without an SSN fax Form SS-4 to 855-215-1627. Mail and phone are also available. The process is identical in every state.
| Method | Speed | SSN Required | Cost |
|---|---|---|---|
| Online | Instant | Yes | $0 |
| Fax | 4-7 business days | No | $0 / $49 |
| Phone (800-829-4933) | Same day | No | $0 |
| 4-6 weeks | No | $0 |
The online tool is the fastest path, but it requires an SSN or ITIN. A non-US resident without an SSN cannot use it. That applicant uses the fax method with a passport number instead. See how to get an EIN for the full walkthrough.
