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.
Illinois will grant you an additional extension to file of more than six months (seven months for corporations) if the Internal Revenue Service (IRS) grants you an additional extension. If you do not owe any tentative tax, you are not required to file Form IL-505-B.
