Reminder: Pass-Through Entity Tax Returns Due March 15
As a result of Public Act 18-49, signed into law on May 31, 2018, the Pass-Through Entity (PE) Tax return is due on the fifteenth day of the third month after the end of the PE’s taxable year.
For calendar year filers, the due date is March 15.
PEs may request a six-month extension (electronically only) to file their PE Tax return. An extension request does not extend the time to pay the tax due. Full payment must be made by the original due date.
