As an international student or scholar at Indiana University, you will likely need to file a federal tax return each year. You may also need to file a state tax return.
Most people who engage in trade or business (including studying, teaching, or performing research) in the United States must file a tax return each year. You will file your tax return with the Internal Revenue Service (IRS).
Your federal tax return indicates how much you owe in federal 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.
