What is the deadline for filing state taxes in Illinois?

Asked a year ago
The deadline for filing state taxes in Illinois is usually April 15th. However, for the tax year 2020, the deadline has been extended to May 17th, 2021, to provide taxpayers with additional time to prepare and file their returns due to the ongoing COVID-19 pandemic. It is important to note that this extension applies to individual income tax returns, as well as any associated payments. If an individual requires more time beyond the extended deadline, they can request an additional six-month extension, which would make the final deadline for filing their state taxes October 15th, 2021. Regardless of the deadline, taxpayers are encouraged to file their returns electronically for faster processing and to choose direct deposit for any tax refunds to receive them more quickly.
