Roughly one in five eligible taxpayers skips the Earned Income Tax Credit every year, and the IRS is sitting on billions in unclaimed money because of it.
The credit is one of the largest anti-poverty programs in the country, yet millions of working Americans leave it on the table — often because they assume they make too little to file a return at all.
The EITC is refundable, meaning it can pay out more than you owe, even if your tax bill is zero.
For the 2024 tax year, the maximum credit runs from $632 for workers with no children up to $7,830 for families with three or more qualifying kids.
The income ceilings are higher than most people expect.
A single worker with three children can earn up to $59,899 and still qualify.
A married couple filing jointly with three kids can bring in $66,819.
Workers without children — long the group most likely to skip the credit — can earn up to $18,591 if single and $25,511 if married.
Married couples must file jointly to claim the EITC in almost every case, and that trips up plenty of households where one spouse assumes they earn too much to bother.
Children must meet relationship, age, and residency tests, and everyone listed needs a valid Social Security number.
The agency estimates that about 20% of eligible workers never claim it.
Some are self-employed gig workers who don't realize their 1099 income counts.
Others are grandparents raising grandchildren, or people who moved mid-year and never got the paperwork.
There's a second pile of money tied to this: the Child Tax Credit.
Many families qualify for both, and the combined refund can run into the thousands.
Free filing options exist through IRS Free File and the agency's Direct File pilot in participating states, so the cost of claiming it is often zero.
You have three years from the original filing deadline to claim a refund.
After that, the money goes to the Treasury permanently.
That means returns from 2021 are expiring right now, and the IRS says roughly $1 billion in unclaimed refunds from recent years is already at risk of being lost for good.
Watch for calls, texts, or emails demanding a fee to "release" your EITC refund, or tax preparers promising inflated credits for a cut.
The IRS never calls demanding immediate payment, and legitimate preparers sign the return they file.
If you think you missed a credit, amended returns are straightforward.
You can file a 1040-X electronically, and the IRS has been processing them faster than in past years.
A free tax clinic or VITA site can handle it for you at no cost if you qualify.
The takeaway is simple: this isn't a loophole or a handout.
It's a credit Congress built specifically for people who work and don't earn much, and it's been underused for decades.
Final Thoughts
Check your eligibility before the three-year window closes — the money is already yours, but only if you ask for it.
