Question

Can you tell me how to file for a state of Illinois tax extension for 2017? The option is not appearing on the size of Turbo Tax screen.

llinois automatically grants a 6-month extension to October 15, 2018. You do not need to fill out an extension form.

However, if you owe additional Illinois taxes, you'll need to submit payment by April 17, 2018 to avoid penalties. You can either print and mail Form IL-501-I along with your check payment, or make an electronic payment through the State of Illinois Web Pay site.
