Extension of Time to File

What should you do if you cannot file your Indiana individual income tax return by the due date? Here's what you need to know:

  • The due date for 2021 Indiana Individual Income Tax returns was April 18, 2022.
  • Filing for an extension does not extend the deadline for paying any tax due. If you expect to owe taxes after filing a return, you should pay at least 90% of the expected amount owed by the original return due date. Interest is due on all amounts paid after the original return filing due date.
  • If you have a federal extension of time to file, you automatically have an extension of time to file with Indiana. You must file your 2021 state tax return by November 14, 2022, and pay any balance due with that filing. While interest is due on any amount paid after the April 18, 2022, due date, penalty will be waived if both of the following conditions are met:
    • You paid at least 90% of the tax expected to be owed by the original April 18, 2022, due date, and
    • The remaining balance due is paid in full by November 14, 2022.
  • If you do not have a federal extension of time to file, and you cannot file by the April 18, 2022, due date, you can request an extension of time to file with DOR. This can be done electronically via INTIME or by completing and filing an Application for Extension of Time to File (Form IT-9)* by mail on or before April 18. This extends the due date to November 14, 2022.

    Form and any payment should be sent to:
    Indiana Department of Revenue
    P.O. Box 6117
    Indianapolis, IN 46206-6117

  • Military personnel on active duty outside of the United States and Puerto Rico will be allowed an automatic 60-day extension.
  • Military personnel serving in a combat zone have an automatic extension of 180 days after they leave the combat zone. If they are hospitalized outside the U.S. as result of this service, the 180-extension period starts upon release from the hospital.
