Illinois Department of Revenue to Waive Penalty for Late Filing of Business Income Tax Returns Due October 15

The Illinois Department of Revenue (Department) announced that it will grant abatement of late filing penalties for taxpayers that file their Illinois business income tax returns on or before November 15 and request penalty waivers for reasonable cause. The Department stated that it will waive late penalties due to the “complexity” of recent federal tax reform and possible taxpayer challenges in meeting the October 15 extended filing deadline for federal and state purposes.
