If you need additional time to file your state tax return by the due date, you can request an extension of time to file. You must make this request before the tax deadline.
If you have a federal extension of time to file, you automatically have an extension with Indiana. You do not have to have a federal extension of time to file to request an extension with DOR.
Requesting an extension of time to file does not extend the deadline for paying any tax due.
How to Submit an Extension Request
Online via INTIME: Instructions are available to guide you through the process of requesting an extension of time to file electronically via INTIME.
Mail: Complete and file an Application for Extension of Time to File (Form IT-9)* to send to DOR by mail on or before the due date.
What's next?
After an extension of time to file request has been submitted, you have until Nov. 15, 2024, to file your 2023 Indiana state tax return and pay any outstanding balance due. Interest will be added to any amount owed after April 15, 2024, but the penalty will be waived if both of the following conditions are met:
- You pay at least 90% of the tax expected to be owed by the original due date, and
- The remaining balance due (including interest) is paid in full no later than Nov. 15, 2024.
Military Personnel
Active Duty: Military personnel on active duty outside the U.S. and Puerto Rico will be allowed an automatic 60-day extension.
Serving in a Combat Zone: Military personnel serving in a combat zone have an automatic extension of 180 days after leaving the combat zone. If hospitalized outside the U.S due to service, the 180-day extension starts upon release from the hospital.
