Every January, millions of Americans file their taxes and hand over more money than they owe.
Not because they made a mistake, but because they never claimed a credit designed specifically for them.
It's called the Earned Income Tax Credit, or EITC.
The IRS estimates that roughly one in five eligible workers skips it every year.
For the 2022 tax year alone, that added up to about $7 billion left on the table, according to IRS data.
The average credit that year was around $2,541 — real money for people who worked hard for every dollar.
The EITC is a refundable credit, which is the part that trips people up.
Refundable means it doesn't just reduce what you owe.
If the credit is bigger than your tax bill, the government sends you the difference as a refund.
So a single parent with two kids who earned $30,000 might owe nothing at all and still get a check for several thousand dollars.
The rules hinge on income and family size, and the income limits adjust most years for inflation.
For the 2024 tax year, workers with three or more qualifying children can earn up to $59,899 if single or $66,819 if married filing jointly and still claim the credit.
With no children, the ceiling drops to $18,591 for singles.
Age matters too: childless workers generally must be between 25 and 64, though the age range for those with children is wider.
Many assume they earn too little to file a return at all, so they skip it.
Filing is exactly how you claim the credit, and a refund may be waiting.
Others assume they make too much, not realizing the limits are higher than they think.
Gig workers, delivery drivers, and self-employed folks often miss out because their income arrives on 1099 forms instead of a W-2.
The credit counts that income too, as long as it's reported.
Same goes for people who worked part of the year or bounced between jobs.
The fastest way to check is the IRS's free EITC Assistant tool, which walks you through a handful of questions.
Free filing options exist through IRS Free File for people under the income threshold, and many volunteer tax prep sites around the country handle returns at no cost.
A certified preparer or the IRS's own tool can confirm eligibility in minutes.
One warning worth repeating: the EITC is one of the most common targets for tax scammers and shady preparers who promise inflated refunds and pocket fees.
If someone claims they can get you a bigger credit than the IRS calculator shows, walk away.
If you worked last year and your income was modest, spend ten minutes checking whether this credit applies to you.
The worst outcome is finding out you don't qualify.
Final Thoughts
The best outcome is a refund you've been owed all along.
