My neighbor Maria called me in a panic last week, staring at a printed tax summary her preparer had handed back to her. She’d already filed. Her refund was $740. She had two kids, worked part-time, and made under $32,000 last year. Something was off — and when I walked through her return with her, I found it immediately: she hadn’t claimed the Earned Income Tax Credit. Not a cent of it. The credit she was entitled to was worth over $6,000.
Maria’s situation is not rare. According to the IRS Earned Income Tax Credit Central, approximately one in five eligible taxpayers fails to claim the EITC every single year. That’s roughly 20 percent of people who qualify walking away from money that is legally theirs.
What the EITC Actually Is — and Why It’s Designed to Be Confusing
The Earned Income Tax Credit is a refundable federal tax credit for low-to-moderate income workers and families. Refundable means that if the credit exceeds what you owe in taxes, the IRS sends you the difference as a refund check. It’s not a deduction. It’s not just a reduction in your tax bill. It’s actual money returned to you.
Congress created the EITC in 1975 as an alternative to direct welfare payments, designed to incentivize work. It has survived decades of political change because both parties have historically supported it. But the structure of the credit is built on a sliding scale that phases in and then phases out based on income — and that complexity trips up millions of filers every year.
The credit amount depends on three things: your earned income, your adjusted gross income (AGI), and the number of qualifying children in your household. There’s no single number to remember. The IRS recalculates eligibility thresholds annually for inflation, which means the rules for 2025 are slightly different from 2024.
The Income Thresholds for 2025 — Where Most People Get Lost
Here’s the thing the IRS won’t proactively call you about: the income limits for the EITC are higher than most people assume. Many workers earning in the mid-to-upper $50,000 range with two children still qualify. The phase-out doesn’t cut off sharply — it slopes downward, which means you might receive a partial credit even when you think you’ve earned too much.
For tax year 2025, the income thresholds are as follows. These are the maximum AGI and earned income limits to receive any credit at all:
These numbers come directly from IRS EITC tables for 2025. Notice that a married couple with three children can earn nearly $67,000 and still receive a meaningful refund through this credit. That’s not a poverty-line benefit — that’s middle-income territory.
The Qualifying Child Rules That Quietly Disqualify Millions
The second place where families lose the EITC is the qualifying child test. The IRS doesn’t just ask whether you have kids — it asks whether those kids meet four specific tests: age, relationship, residency, and joint return. Failing any one of the four means the child doesn’t count for the credit.
The age test alone catches a lot of people off guard. A child must be under 19 at the end of the tax year — or under 24 if they’re a full-time student. But there’s no age limit if the child is permanently and totally disabled. Grandparents raising grandchildren sometimes miss this entirely because they assume they don’t qualify.
- Age test: Under 19, under 24 if full-time student, or any age if permanently disabled
- Relationship test: Must be your child, stepchild, foster child, sibling, or a descendant of any of these
- Residency test: Must have lived with you in the U.S. for more than half the tax year
- Joint return test: The child cannot file a joint return with a spouse (with limited exceptions)
If you share custody of a child, there’s an additional layer: only one parent can claim the child for EITC purposes in a given year — and it must be the parent with whom the child lived longer. This is different from the dependency exemption rules, which can be transferred between parents. The EITC custody rule cannot be transferred via a signed agreement.
How to Claim What You’re Owed Before April 15, 2026
If you haven’t filed yet, you can claim the EITC directly on your Form 1040. Tax software will walk you through Schedule EIC if you indicate you have qualifying children. The IRS also offers a free filing option through IRS Free File for taxpayers with adjusted gross income under $84,000 in 2025.
If you already filed and missed the credit, you can still fix this. Filing an amended return using Form 1040-X allows you to go back and claim the EITC you missed. The statute of limitations for amended returns is generally three years from the original filing date — but there’s a specific rule: for EITC claims, the three-year window runs from the original due date of the return, not when you actually filed.
The Bigger Picture: $57 Billion Left Unclaimed Each Year
The IRS estimates that roughly $57 billion in EITC goes unclaimed or is lost to errors annually. Some of that is fraud — EITC is one of the most audited credits because improper claims are common. But a significant portion is eligible families who simply didn’t know they qualified, filed with incorrect information, or were scared off by complexity.
The credit has real economic consequences at the household level. For a single mother earning $28,000 with two children, the EITC can represent 25 percent of her annual income — more than two months of wages returned at tax time. Research from the Brookings Institution has consistently linked EITC receipt to improved infant health outcomes, higher school performance in children, and greater long-term earnings for young recipients.
When Maria and I recalculated her return together, she was eligible for $5,980. She’d need to file an amended return, wait a couple of months, but that money was still hers to claim. She looked at the number for a long time before she said anything. “I didn’t know I could do that,” she told me. Most people don’t.
The April 15, 2026 deadline for 2025 tax returns is days away. If you haven’t filed, the EITC eligibility check takes under five minutes at irs.gov. If you have filed and something feels off about your refund amount, pulling up last year’s return and running the numbers through the EITC Assistant costs nothing. The worst outcome is confirming you got everything you deserved. The best outcome might be a check for several thousand dollars that nobody told you was coming.
