Tax season brings out the usual mix of dread and daydreaming about refunds, but there's a specific pot of money that millions of working Americans leave untouched.
It's called the Earned Income Tax Credit, and the IRS estimates that roughly one in five eligible filers never claims it.
That's not pocket change slipping through the cracks—it's thousands of dollars that could land in a bank account instead of staying with the government.
The EITC is designed for people who work but don't earn a lot.
The idea is simple: if you're bringing home wages and your income falls under certain thresholds, the credit reduces what you owe and often triggers a refund even if you owe nothing.
For the 2024 tax year, families with three or more children can qualify for up to $7,830.
Workers without children can still get a smaller credit, and the rules have loosened in recent years to include more people in that group.
Many workers assume they make too little to file a return at all, so they skip it entirely.
Others worry that claiming a credit will trigger an audit or complicate their taxes.
The IRS treats the EITC as a straightforward benefit, and free filing options through IRS Free File and Volunteer Income Tax Assistance sites exist specifically to help people claim it without paying a preparer.
The IRS is legally required to hold refunds that include the EITC until mid-February, which means early filers who claim it may wait a few extra weeks for their money.
That delay sometimes pushes people toward costly tax preparation loans or rapid refund products that eat into the very credit they're trying to collect.
Gig workers, part-time employees, rural families, and people who recently had a change in income like a layoff or a new baby.
Self-employment income counts too, which surprises many rideshare drivers and freelancers.
If you earned money from any source and your income falls under the limit for your family size, it's worth running the numbers before you file.
The simplest way to check is to use the IRS's EITC Assistant tool, which walks you through a few questions and gives a yes-or-no answer in minutes.
If you've already filed and think you missed it, you can amend your return for up to three years back.
That means refunds from prior tax years may still be recoverable, though the clock is always ticking.
State credits can stack on top of the federal one.
About half of states offer their own version of the EITC, and some match a percentage of the federal amount.
If you qualify federally, it's worth checking whether your state adds anything extra—that's often another few hundred dollars most people never think to look for.
The bottom line is that this credit exists because lawmakers decided working people with low incomes deserve a break.
Leaving it unclaimed doesn't help anyone except the Treasury.
