Illinois EITC: A Tax Break Built for Working Families
Tax season can be confusing, especially when you’re trying to figure out which credits you actually qualify for. The good news is that the Illinois EITC is meant to help working taxpayers with low to moderate income keep more money in their pocket. Illinois says the credit reduces tax owed and may even result in a refund.
A key point: you must file a return to claim it, even if you otherwise do not owe tax or are not required to file.
What Is the Illinois EITC?
The Illinois Earned Income Tax Credit is a state tax credit for eligible working taxpayers. Illinois says it follows federal EITC-style eligibility rules in many cases, but the state also has its own important details. For example, Illinois now allows some taxpayers who file with an ITIN or who are at least age 18 and do not have a qualifying child to qualify, if they otherwise meet federal income guidelines.
Why this matters for tax planning
If you are eligible, this credit can be a meaningful piece of your annual tax strategy because it directly reduces tax and can increase refund value.
Who Qualifies for the Illinois EITC?
For tax year 2025, Illinois says you may qualify if you meet all of these conditions:
| Requirement | 2025 Illinois rule |
|---|---|
| Earned income | Under $68,675 overall; the exact limit depends on filing status and number of qualifying children. |
| Investment income | Below $11,950. |
| Tax ID | A valid Social Security number (SSN) or IRS-issued ITIN by the due date of your 2025 return, including extensions. |
| Age | At least 18 by the end of 2025; Illinois says this includes taxpayers ages 18–24 and 65 and older without a qualifying child. |
| Citizenship/residency | Must be a U.S. citizen or resident alien all year. |
| Other tax rules | You cannot file Form 2555, Foreign Earned Income, and special rules apply if you are separated and not filing jointly. |
A helpful note about children
You do not need qualifying children to claim the Illinois EITC, but having one or more qualifying children may increase your credit. Illinois also notes that for the Illinois EITC, a qualifying child may have a valid SSN or ITIN.

How Much Can You Get?
Illinois says the state credit is 20% of the federal EITC. For tax year 2025, the maximum Illinois EITC amounts are:
| Number of qualifying children | Maximum Illinois EITC |
|---|---|
| No qualifying children | $130 |
| 1 qualifying child | $866 |
| 2 qualifying children | $1,430 |
| 3 or more qualifying children | $1,609 |
If you’re planning around your tax refund, these numbers matter because the credit can materially change your final tax outcome.
Extra Benefit: Illinois Child Tax Credit
Illinois says that if you qualify for the 2025 Illinois EITC and have at least one qualifying child under age 12, you also qualify for the Child Tax Credit. That credit equals 40% of your Illinois EITC amount, and you claim it on Schedule IL-E/EITC, Step 5.
How to Claim the Illinois EITC
Illinois explains that you claim the credit on Form IL-1040, Illinois Individual Income Tax Return, by completing Schedule IL-E/EITC and transferring the total from Line 9 of that schedule to Line 29 of your IL-1040.
If you qualified for the federal EITC
If you qualified for the federal EITC, Illinois says you still need to complete Schedule IL-E/EITC. On Step 4, you should not check boxes 5a–5d, and you should not complete the Illinois Expanded EITC Worksheet on Pages 3 and 4.
If your child has an ITIN
If you qualified for the federal EITC but could not claim your child because the child has an ITIN, Illinois says to check box 5d in Step 4 and complete the Illinois Expanded EITC Worksheet on Pages 3 and 4.
If you did not qualify for the federal EITC
If you did not qualify federally because you have an ITIN or did not meet the age rules, but you do qualify for the Illinois EITC, Illinois says to check box 5a or 5b in Step 4, as applicable, and complete the Illinois Expanded EITC Worksheet on Pages 3 and 4.
Common Mistakes to Avoid
1) Missing the filing requirement
You may need to file a return even if you owe no tax, because that is how you claim the credit.
2) Forgetting the investment income cap
Illinois limits 2025 investment income to $11,950 or less. Going over that amount can make you ineligible.
3) Using the wrong schedule steps
Illinois gives different instructions depending on whether you qualify federally, have a child with an ITIN, or only qualify at the Illinois level. Mixing up the boxes or skipping the expanded worksheet can cause filing errors.
4) Forgetting the child tax credit
If you have a qualifying child under 12, you may also be eligible for the Illinois Child Tax Credit worth 40% of your Illinois EITC.
Pro Tips
- Check your earned income and investment income before filing so you know whether you are in range.
- If you have children, review whether your family situation can increase your EITC amount. Illinois says the credit increases with one or more qualifying children.
- If you are eligible for the federal EITC, use that as a starting point, then follow Illinois’ additional state-specific instructions on Schedule IL-E/EITC.
- If your child has an ITIN or you qualify only at the Illinois level, pay close attention to the worksheet instructions.
Final Thoughts
The Illinois EITC is one of the most valuable tax credits for working taxpayers with lower to moderate income. It can lower the tax you owe, increase your refund, and potentially unlock an additional Child Tax Credit if you have a child under 12. If you think you may qualify, it is worth taking the time to check the income limits, age rules, and filing steps carefully.
