Illinois will automatically grant all taxpayers a six-month extension of time to file Form IL-1040. For calendar year filers, the filing date is automatically extended to October 15. You are not required to file Form IL-505-I in order to obtain this automatic extension.
If you owe state tax, you must also make a payment using Form IL-505-I, Automatic Extension Payment for Individuals, by April 18, 2017. You can also pay online with the Illinois Department of Revenue's agency website. After April 18, 2017, you will begin to owe penalties and interest on any unpaid taxes.
