The IRS estimates that roughly one in five workers who qualify for the Earned Income Tax Credit never claim it. That is not a rounding error. For a family with three children, the credit is worth up to $8,046 on a 2025 tax return — real money, fully refundable, sitting unclaimed because people either don't know the credit exists or assume it isn't for them.
Both assumptions are usually wrong, so let's fix them.
What the EITC is, in plain terms
The Earned Income Tax Credit is a refundable federal tax credit for low- and moderate-income workers. "Refundable" is the key word: if the credit is bigger than the tax you owe, the IRS pays you the difference as a refund. Owe zero tax and qualify for a $4,000 credit? You get a $4,000 refund. This is what separates the EITC from most tax breaks, which only reduce a bill you already owe.
The credit phases in as you earn, plateaus, then phases out as income rises — it is designed to reward work, which is why you must have earned income (wages, salary, tips, or self-employment profit) to get it. Investment income alone doesn't count, and in fact too much investment income disqualifies you: the cap is $11,950 for tax year 2025.
How much it's worth for 2025 returns
For tax year 2025 — the return you file in early 2026 — the maximum credits are:
| Children claimed | Maximum credit |
|---|---|
| None | $649 |
| One | $4,328 |
| Two | $7,152 |
| Three or more | $8,046 |
Income limits scale with family size and filing status, topping out at $68,675 for a married couple filing jointly with three or more children. A single filer with no children must earn under roughly $19,100. The IRS publishes the exact thresholds in its EITC tables, which are updated for inflation every year — check the current figures rather than trusting any article's, ours included. Most people don't receive the maximum; the amount depends on where your income lands on the curve. But even mid-range amounts commonly run into the thousands with children in the picture.
Around 31 states plus the District of Columbia also run their own EITCs, typically calculated as a percentage of the federal credit and added to your state refund. If you qualify federally, check your state return for a matching line.
Who qualifies — and who wrongly assumes they don't
The basic requirements for tax year 2025: you (and your spouse, if filing jointly) need a Social Security number valid for employment, earned income under the limit for your family size, investment income under the cap, and you generally cannot file married filing separately. Beyond that, the IRS EITC page has a qualification assistant that walks through the details in a few minutes.
The groups that most often leave the credit on the table:
- Workers without children. The childless credit is small, but it exists — for filers roughly age 25 through 64. Millions skip it because every headline about the EITC mentions kids.
- People who earned too little to owe tax. If your income is below the filing threshold, you are not required to file — but not filing means forfeiting a refundable credit. This is the single biggest reason eligible people miss out. You must file to get paid.
- Grandparents and other relatives raising children. A "qualifying child" for EITC purposes can be a grandchild, sibling, niece, nephew, or foster child who lived with you more than half the year and meets the age rules. Formal custody paperwork is not required.
- Self-employed and gig workers. Net self-employment profit is earned income. If you drove rideshare or freelanced — the kind of work in our side income guide — you may qualify, but you must report the income properly, including paying self-employment tax on it. Reporting less income to shrink your tax bill can also shrink or kill your EITC; report what you actually earned.
- People whose income dropped. Lost a job mid-year? Your annual income may have fallen into EITC range for the first time. Note that unemployment benefits are not earned income — they don't build the credit — but the wages you earned before the layoff do.
The qualifying-child rules, because this is where errors happen
Most EITC mistakes involve who claims a child. The child must be under 19 (under 24 if a full-time student, any age if permanently disabled), must be your child, stepchild, foster child, sibling, or a descendant of one of those, and must have lived with you in the United States for more than half the year. Only one person can claim a given child for the EITC. When parents are separated, the credit follows the parent the child actually lived with most of the year — not the divorce decree, not who pays support. In our experience reading IRS dispute guidance, two households claiming the same child is the fastest route to a frozen refund and a paperwork fight, so settle who claims whom before anyone files.
What counts as earned income — and what doesn't
The credit is built on earned income, and the line matters. Wages, salaries, tips, union strike benefits, net earnings from self-employment, and certain disability payments received before minimum retirement age all count. What doesn't count: unemployment benefits, Social Security, SSI, child support, alimony, interest and dividends, pensions, and withdrawals from retirement accounts. A household living entirely on unemployment checks for a year has no earned income and no EITC — but a household that worked three months and collected benefits for nine calculates the credit on those three months of wages.
Two special rules are worth knowing. Members of the military can elect to count nontaxable combat pay as earned income when that produces a bigger credit — run the numbers both ways. And clergy housing allowances have their own treatment that trips up software; a VITA site or preparer familiar with ministerial returns is worth seeking out.
Errors that trigger IRS letters
The EITC has one of the higher error rates in the tax code, which means returns claiming it draw extra scrutiny. The classic mistakes: two households claiming the same child, filing as head of household while married and living together, self-employment income reported with no records behind it, and Social Security numbers that don't match names after a marriage or adoption. If the IRS disallowed your EITC in a past year for anything beyond a math error, you'll need to attach Form 8862 to claim it again — skipping that form gets the new claim rejected automatically.
The defense is boring and effective: keep school, medical, or lease records showing where your children lived during the year, keep real books for any self-employment, and answer any IRS letter by its deadline. Most EITC audits are correspondence audits — paperwork by mail, not an agent at your door — and taxpayers with documentation routinely win them.
How to claim it without paying anyone
- File a federal return, even if you owe nothing, and complete Schedule EIC if you're claiming children.
- Use free filing. If your income qualifies you for the EITC, it almost certainly qualifies you for IRS-sponsored free tax preparation. VITA sites prepare returns at no charge with IRS-certified volunteers who handle the EITC every day — our VITA guide explains how to find a site and what to bring. Paying $300 at a storefront preparer to claim an anti-poverty credit is a bad trade.
- Expect a slight refund delay. By law, the IRS cannot release refunds on returns claiming the EITC before mid-February, even if you file in January. Beware of preparers selling "refund advances" against this wait; the fees eat into money that is already yours.
- Look backward. You can generally file or amend returns up to three years back. If you qualified in 2023 or 2024 and never filed, those credits are still claimable — until the window closes.
One more thing worth knowing
Federal tax refunds, including the EITC, do not count as income for federally funded benefit programs, and money you save from a refund is disregarded as an asset for at least 12 months. Claiming the credit will not cost you SNAP, Medicaid, SSI, or housing assistance. The programs are designed to stack.
Your next step is fifteen minutes: run the EITC Assistant on irs.gov with last year's income figures. If it says you may qualify, book a free VITA appointment before the mid-season rush — slots go fast from late January on.
