The State of Indiana will automatically grant you a tax extension if you have a valid federal tax extension (IRS Tax Form 4868 ). If you do not need to make a tax payment and have received an acceptance notification from FileLater, then there’s nothing more for you to do.

If you don't have a valid federal tax extension, you can submit Form IT-9 (PDF) to extend your tax deadline. You will also need to submit Indiana Form IT-9 if you need to make a state tax payment (regardless if you have an accepted federal tax extension).

Filing for a Indiana tax extension will not provide you with additional time to pay any tax balance due, which must be paid by the original filing deadline or interest and other payment penalties may apply.
