Upcoming estimated tax payments can be based on 100% of estimated liabilities for the current year or 100% of the taxpayer's actual tax liability for 2019 or 2018, the department said in a Thursday bulletin. Illinois previously extended its income tax return dates to July 15 from April 15, but the due dates for estimated payments haven't changed.
If a resident or corporation requests a carryforward of an overpayment for 2019, the overpayment can be applied against an estimated payment received on or before April 15, the bulletin said.
