In addition to filing a federal tax return, you may be required to file a state tax return each year.
Most people who earn income in the state of Indiana are required to submit a tax return to the Indiana Department of Revenue (DOR) each year.
Your state tax return indicates how much you owe in state taxes and how much you actually paid. If your return shows that you did not pay enough, you will be required to pay the remaining amount. If you paid too much, you will receive a refund.
