Illinois Filing Deadlines Impacted by Federal Extension
March 21, 2020

While no official announcement by the State of Illinois has been issued at this time, Section 505(b) of the Illinois Income Tax Act states that a taxpayer that is granted an extension to file his federal income tax return for any taxable year will automatically be allowed an extension of the due date of the state return for the same period. For corporations – if the requirements of Section 602 are met – the extension is for an additional month beyond the federal extension.

The Illinois Department of Revenue will be posting updates for Illinois taxpayers. Please contact your Miller Cooper representative if you have any questions.
