IL State Income Tax Filing Extended to May 17th to Coincide with Federal Deadline

Today the Illinois Department of Revenue (IDOR) announced that they will extend the individual income tax filing and payment deadline from April 15 to May 17.

IDOR will continue to process tax refunds for those filing ahead of the deadline. The filing extension does not apply to estimated tax payments that are due on April 15, 2021. These payments are still due on April 15 and can be based on either 100% of estimated or 90% of actual liability for 2021, or 100% of actual liabilities for 2019 or 2020.

According to IDOR, 2.4 million taxpayers have already filed their individual income tax returns to date. Over 79% of the taxpayers that have already filed are expecting a refund this year. Last year, over 6.4 million income tax returns were filed, and 87% of people filed electronically.

The filing extension for individual income tax takes effect automatically, so no further action is required by taxpayers to take advantage. For taxpayers awaiting a refund, utilize IDOR’s Where’s My Refund? to locate specific information about the status of any refund due.

Free filing of Form IL-1040 is available through MyTax Illinois. Individuals may also utilize MyTax Illinois to make payments, respond to department inquiries, and check the status of their Illinois Individual Income Tax refunds using the Where’s My Refund? link. Taxpayers may also look up IL-PINs, amounts of any estimated tax payments made, and (when necessary) amounts reported on Form 1099-G with MyTax Illinois.
