Governor JB Pritzker has directed the Illinois Department of Revenue (IDOR) to follow the federal government in providing special tax filing and payment relief to individuals and businesses in response to the COVID-19 Outbreak.

The filing and payment deadline for Illinois income tax returns has been extended from April 15, 2020 to July 15, 2020.
This filing and payment relief includes:
The 2019 income tax filing and payment deadlines for all taxpayers who file and pay their Illinois income taxes on April 15, 2020 are automatically extended until July 15, 2020. This relief applies to all individual returns, trusts, and corporations. This relief is automatic and taxpayers do not need to file any additional forms or call IDOR to qualify.
Penalties and interest will begin to accrue on any remaining unpaid balances as of July 16, 2020. You will automatically avoid interest and penalties on the taxes paid by July 15, 2020.
Note: This does NOT impact the first and second installments of Illinois estimated payments for 2020 taxes that are due April 15 and June 15. Taxpayers are required to estimate their tax liability for the year and make four equal installments. Taxpayers will not be assessed a late estimated payment penalty if the amount of the installments equals 90% or more of the current year’s liability or 100% of the previous year’s liability.
Taxpayers can find more information, including common questions and answers, on the Illinois Department of Revenue website at tax.illinois.gov.
