Regulatory Update

December 2016

The Illinois Department of Revenue (IDOR) recently announced changes to state tax return due dates for C corporations for the 2016 filing season. See IDOR Guidance.

  • Calendar Year C corporations will receive an extra month to file their returns and pay any taxes owed. The original filing and payment due date will change from March 15, 2017 to Tuesday, April 18, 2017.
  • Fiscal year C corporations, whose tax year ends on a date other than June 30, will also receive an extra month to file returns and mpaymentake tax s. Their original filing and payment due date will be changed to the 15th day of the 4th month following the close of the tax year.
  • There are no changes to original filing dates for S corporations, partnerships, trust/estates, or exempt organizations in Illinois.

Working with IDOR & the General AssemblyICPAS’ State and Local Tax Committee and the Government Relations Office has been working with IDOR on this issue. IDOR has administratively adjusted filing due dates for the 2016 filing season, however, legislation is needed for a long-term remedy.We will continue to work with the IDOR on legislative language that recognizes the new federal due dates and maintains the logical and efficient flow of information for state returns.
