State tax returns with federal extensions due Nov. 15

INDIANA – Customers who qualified for an extension of time to file must have their 2020 Indiana Individual Income Tax returns filed by Nov. 15, 2021, and pay any balance due with that filing.

Although interest is due on any amount paid after the May 17, 2021, due date, the penalty will be waived if both of the following conditions are met:

  • The customer paid at least 90% of the tax expected to be owed by the original May 17, 2021 due date, and
  • The remaining balance due is paid in full by Nov. 15.

Payment of taxes due can be made through INTIME at See our “Extension of Time to File” page on for more information, including automatic extensions for some military members.
