The tax credit 1 in 5 people never claim
How we make money: when you sign up for an offer we recommend, we may earn a commission. It costs you nothing extra, and it never decides what makes the list — more on how this works.
About one in five people eligible for the Earned Income Tax Credit don’t claim it — roughly 5 million people leaving around $7 billion unclaimed every year (Taxpayer Advocate Service). For tax year 2026 the credit is worth up to $664 with no children, $4,427 with one, $7,316 with two, and $8,231 with three or more (IRS). And of the roughly 5 million who miss it, 3.3 million never file a return at all — which is the whole problem in one number.
This is the single largest pot of money in the US that eligible people simply don’t collect. Here’s who it’s for and how to get it, including for years you’ve already missed.
What makes this one different: it’s refundable
Most tax credits reduce what you owe. Once your bill hits zero, they stop being worth anything.
The EITC is refundable, which means if the credit is larger than your tax bill, the IRS pays you the difference as a refund. Someone who owes no federal income tax at all can still receive the full amount as cash.
That’s why the “I don’t earn enough to file” instinct is so expensive. If your income is low, you may not be *required* to file — but filing is the only way the money reaches you. The 3.3 million non-filers above aren’t making a mistake on a form. They’re skipping the form.
Who it’s for
Broadly: people who work, earn a low-to-moderate income, and have earned income from a job or self-employment.
Two misconceptions worth correcting directly.
You don’t need children. The childless version is much smaller — up to $664 for 2026 — but it exists, and the age band for it is narrower. Plenty of people assume EITC is a parents-only credit and never look.
Self-employment counts. Gig work, driving, freelance income, selling online — that’s earned income. You’ll need to have reported it.
The specific income cutoffs change every year and vary by filing status and number of children, which is exactly the complexity that causes people to give up. Rather than publish figures that go stale, use the IRS’s own tool: the EITC Assistant walks you through it and gives you an answer. The full 2026 thresholds are published in Revenue Procedure 2025-32.
One firm limit worth knowing: investment income has to stay under $12,200 for 2026. That includes interest, dividends, capital gains, and rental income.
You can claim it for past years
This is the part almost nobody knows, and it’s where the real money often sits.
If you were eligible in a previous year and didn’t claim it, you can generally still file — or amend — and collect. The window is three years from the original filing deadline for that year, or two years from when you paid the tax, whichever is later (Taxpayer Advocate Service).
Miss that window and the refund is gone permanently — the IRS keeps it, and you can’t apply it to another year.
So if your circumstances have changed, or you had a low-income year you didn’t file for, it’s worth checking the last three years rather than only the current one. For someone who qualified with children across three missed years, this is not a small sum.
Why so many people miss it
The reasons are consistent and none of them are carelessness:
- The rules are genuinely complicated. Eligibility depends on income, filing status, qualifying-child tests, age, and residency. Complexity is the most-cited cause.
- People don’t realize they qualify. Particularly those who’ve never claimed it before, whose income dropped recently, or who don’t have children.
- They don’t file. If you’re under the filing threshold, nothing prompts you.
- Circumstances change year to year. Eligibility isn’t permanent in either direction. Not qualifying three years ago tells you nothing about this year.
How to claim it without paying for the privilege
You do not need to pay a preparer to get this credit, and paying a percentage of your refund to a service is the most expensive way to collect it.
- IRS Free File offers free guided tax software if your income is under the published threshold.
- VITA — Volunteer Income Tax Assistance — provides free, IRS-certified in-person help, and is specifically aimed at people who qualify for credits like this one. Sites fill up in filing season, so book early.
- File even if you don’t have to. For a lot of people this is the entire action item.
Be wary of refund-anticipation products and any service that takes a cut of the credit. The money is the point; fees against it defeat the exercise.
The short version
If you worked at all last year and your income was modest, spend twenty minutes with the EITC Assistant. If you had a low-income year in the last three that you didn’t file for, check that too, because the door closes three years after the deadline and doesn’t reopen.
