The Indiana Department of Revenue (DOR) will start accepting filings for 2021 individual income tax returns on Monday, Jan. 24, in concert with the Internal Revenue Service (IRS). Customers will have until Monday, Apr. 18, to file both their state and federal 2021 tax returns and pay any taxes owed.

DOR encourages customers not to file their state tax returns prior to Jan. 24 or before they have gathered all necessary documentation. Attempting to file without all documents can delay the process and ultimately postpone any refund a customer may receive.
