The Illinois Department of Revenue (IDOR) is reminding taxpayers that the upcoming deadline for filing 2021 state individual income tax returns is Monday, April 18, 2022. To aid in IDOR’s anti-fraud efforts, taxpayers filing their IL-1040’s through MyTax Illinois, must use a registered MyTax Illinois account. If they do not have a registered account, they may create one by choosing “sign up” in the login box at MyTax Illinois and follow the instructions. The ID number will be mailed to them within 10 days after being requested. While IDOR strongly encourages electronic filing, taxpayers can always file a paper return if they choose. If a taxpayer electronically files an error-free return, they should receive a direct deposit refund in approximately four weeks. While the state of Illinois does grant an automatic six-month extension to file an IL-1040 each year, taxpayers must still pay any money owed on their returns by April 18 to avoid penalties and interest. To assist taxpayers with last minute questions, IDOR will also have extended telephone hours on Friday, April 15 from 8:00 a.m. to 7:00 p.m. and Monday, April 18 from 7:30 a.m. to 7:00 p.m. For the most up-to-date information, forms, schedules, and instructions for the 2022 tax season, please visit IDOR’s website at: tax.illinois.gov.
