Illinois Income Tax Filing and Payment Extension

Please note that this blog is based on laws effective March 26, 2020 and may not contain later amendments. Please contact Cray Kaiser for most recent information.

Illinois taxpayers received welcome relief on March 25 as Illinois largely followed the Internal Revenue Service guidance on the April 15, 2020 tax deadline.

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 automatic relief applies to all individual returns, trusts, and corporations. These taxpayers will automatically avoid interest and penalties on any taxes due that are paid by July 15, 2020. Penalties and interest will begin to accrue on any remaining unpaid balances as of July 16, 2020, same as payments due to the Internal Revenue Service.

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 submit quarterly installments as normal. 

Further guidance from the IRS regarding the federal tax filing extension:

  • No limit on amount subject to relief
    Our last update indicated that there would be caps on the amount of taxes due that would be subject to relief from interest and penalties. The cap has since been lifted; therefore, no interest or penalty will accrue on federal income taxes due on April 15, 2020 but not paid until July 15, 2020. This is a welcome relief to larger corporations and high net worth individuals.
  • Clarification on which tax forms are eligible for the automatic extension
    Not only individuals qualify for the automatic extension. Trusts, estates, and various corporations with an April 15, 2020 due date also receive the automatic filing and payment extension to July 15, 2020.
  • Clarification on which tax forms are not extended
    The IRS notes that normal filing, payment, and deposit due dates continue to apply to both payroll and excise taxes. Additionally, estate and gift taxes do not receive a payment or filing extension.
  • Federal estimated tax due dates remain confusing
    As we write this today, technically, the 1st quarter 2020 federal estimated tax payment is now due on July 15, 2020. However, there has been no update to the due date for the 2nd quarter federal estimated tax payment, so it remains due on June 15, 2020. Confusing, indeed! We hope to receive clarification and perhaps an extension of the due date of the 2nd quarter estimated tax payment. For now, plan on paying a quarterly estimate on both June 15, 2020 and July 15, 2020 until we receive further guidance.
  • Confirmation of due date for Individual Retirement Accounts (IRA) and Health Savings Accounts (HSA) IRA deposits
    The IRS has indicated that these deposits are also due on July 15, 2020.
