2024 Illinois Form 1040

What Is Illinois Form IL-1040?

Illinois Form IL-1040 is used by full-year residents, part-year residents, and nonresidents to file their state income tax return. The purpose of Form IL-1040 is to determine your tax liability for the state of Illinois. Nonresident and part-year resident filers are also required to complete Illinois Schedule NR.

The State of Illinois does not have an Easy Form (EZ) or Short Form. Read the General Information section of the IL-1040 instructions book to help determine if you should file as a full-year resident, part-year resident, or nonresident for tax year 2024.

Who Must File Illinois Form IL-1040?

You must file an Illinois tax return if you were required to file a federal income tax return. There is also an income test for those who were not required to file a federal income tax return. You must file an Illinois tax return if your Base Income (line 9) exceeds your total Exemptions claimed (line 10). For tax year 2024, Single residents under the age of 65 must file if their income is more than $2,425. Married residents with no dependents must file if their income is more than $4,850.

Even if your Base Income is below the amount specified for the total exemptions claimed, you may still want to file an Illinois tax return. You may receive a refund for the state tax amount shown on your Illinois W-2, for example. You may also be eligible for any Illinois earned income credit or other low-income related credits.

Read the Who Must File section of the IL-1040 instructions book to help determine if you should file a state income tax return for tax year 2024.
