The Earned Income Tax Credit

The short version

The Earned Income Tax Credit (EITC) is a federal tax credit for low-to-moderate-income working people. For 2024 tax returns filed in 2025, a family with three or more qualifying children could receive up to approximately $7,830. Illinois has its own state EITC that adds to the federal credit. You must file a tax return to claim it, even if you owe no tax — millions of eligible people miss it because they don't file.

How the EITC works

The EITC reduces the amount of tax you owe. It is refundable — if the credit exceeds what you owe, you get the rest as a refund. That means even workers who owe no tax can receive thousands of dollars back.

The credit amount depends on three things:

  1. Your earned income (wages, self-employment income, certain disability benefits)
  2. Your filing status (single, married filing jointly, head of household)
  3. Number of qualifying children (0, 1, 2, or 3+)

Maximum federal EITC amounts (2024 tax year — file in 2025)

These are maximums. Actual credit varies based on income. Amounts update annually for inflation — check IRS EITC for the current year.

Income limits (2024 tax year)

To qualify for any EITC amount, adjusted gross income must be below the following thresholds. Amounts differ by filing status and number of qualifying children.

Investment income must also be below approximately $11,600 to qualify.

Who is a qualifying child

A qualifying child must:

Children born or adopted during the year can qualify if they lived with you the rest of the year.

Requirements for all filers

Illinois EITC

Illinois has its own EITC equal to 20% of the federal EITC (rate set by state law; check current rate). You claim it on your Illinois tax return (Form IL-1040), Schedule IL-E/EIC. Illinois EITC is also refundable — you get it even if you owe no state tax.

A family getting $6,000 in federal EITC would get another $1,200 from Illinois.

Free tax preparation

Filing a tax return to claim EITC does not cost you anything. Paid preparers sometimes charge high fees or push refund-anticipation loans. Free options are widely available:

Claiming prior-year EITC

If you missed the EITC in a prior year, you can still claim it by filing or amending returns for up to 3 years back. For tax year 2021 (filed in 2022), the deadline to amend is generally April 15, 2025. For tax year 2022, amend by April 15, 2026. Many people leave thousands of dollars unclaimed by not filing back returns.

Common reasons eligible people don't claim EITC

The IRS estimates that about 20% of eligible households miss EITC each year. If you worked and earned low-to-moderate income, check your eligibility — the claim is almost always worth more than the time it takes.
