IRS Warns 20 Million Non-Filers: Earned Income, Child, and Education Tax Credits Await

(UNITED STATES) — The IRS warned that millions of eligible non-filers may be leaving refunds and tax credits unclaimed by failing to file a tax return, even when they do not owe tax or fall below the usual filing threshold.

At the center of that warning are three credits that can put cash back into households: the Earned Income Tax Credit, the Additional Child Tax Credit and the American Opportunity Tax Credit. The agency said taxpayers must file a return to claim them.

For many people, that filing step matters as much as eligibility itself. Refundable and partially refundable credits can produce a refund that exceeds the amount of tax owed, but no payment goes out if no return is filed.

The warning applies to the 2025 tax year, when credit amounts and eligibility rules again vary by income, filing status and family circumstances. That annual variation means taxpayers who did not qualify in a prior year may qualify now, while others may need to check whether changes in income or household size affect what they can claim.

Non-filers can include workers with low or moderate earnings, people whose income falls under standard filing thresholds, and households that assume no return is needed because no federal income tax is due. The IRS warning makes clear that a lack of filing requirement does not remove the need to file when a taxpayer wants to claim a refundable credit or recover withholding.

That point carries weight for people who miss a filing season and plan to come back later. The IRS holds refunds for unfiled prior returns, but taxpayers must claim them within 3 years of the due date or lose them.

Among the credits highlighted, the Earned Income Tax Credit stands out because it is fully refundable and can vary widely depending on earnings, family size and filing status. For the 2025 tax year, the agency’s example showed the credit can reach up to $5,891 for families with qualifying children if income is under ~$50,270.

The Earned Income Tax Credit reaches beyond a narrow group of taxpayers. The IRS warning said eligible claimants can include low- and moderate-income workers, grandparents raising grandchildren, veterans, self-employed people, taxpayers without qualifying children and people whose income falls below filing thresholds.

Even with that broad reach, many do not collect it. Four in five eligible workers claim it, but millions miss out.

The Additional Child Tax Credit also can return money to families that file. For 2025, it can provide up to $1,700 per qualifying child as part of the $2,200 Child Tax Credit, and the refundable portion can reach up to $1,700 per child.

To claim that credit, the child must be under 17 at year-end, be claimed as a dependent and have a valid SSN for employment. Taxpayers must file Schedule 8812.

For families with several children, that filing requirement can shape whether they receive a large refund or none at all. The IRS warning emphasized that the credit does not arrive automatically just because a taxpayer has children who meet the age and dependency tests.

The American Opportunity Tax Credit offers another route to a refund for households paying college costs. It is worth up to $2,500 per eligible student, with up to $1,000 refundable.

That credit applies to the first 4 years of higher education. The income limits in the IRS summary put modified AGI at ≤ $90,000 for single filers and $180,000 for joint filers, and taxpayers must file Form 8863.

For households balancing wages, tuition bills and child-related expenses, the difference between filing and not filing can run across more than one credit. A worker with children and a student in college, for example, may need to review both the Additional Child Tax Credit and the American Opportunity Tax Credit before deciding that a return is unnecessary.

The IRS warning also pointed to other credits that can produce refunds. The Adoption Tax Credit reaches $17,280 per child for 2025, with up to $5,000 refundable, for taxpayers who finalized or started an adoption in 2025.

The Premium Tax Credit remains fully refundable and varies by income and the cost of a Marketplace health plan. That means taxpayers who bought health insurance through the Marketplace may need to file even if their earnings would not otherwise trigger a filing requirement.

Taken together, those provisions show why the agency framed the issue as more than a routine filing reminder. The message was that a decision not to file can close off access to cash benefits written into the tax code.

That warning also lands on people who assume a small paycheck or inconsistent work makes filing irrelevant. The IRS noted that some taxpayers under income thresholds may still qualify for credits or refunds of amounts withheld from wages, and a return is the only way to receive them.

One example in the agency’s summary cited a single filer under the $12,550 standard deduction threshold. For taxpayers in that position, the lack of a filing requirement does not prevent eligibility for a refund.

The practical steps the IRS outlined begin with collecting income records. Non-filers trying to claim unfiled refunds should gather W-2s and 1099s, and those who cannot find them can request free transcripts from the IRS.

From there, the agency said taxpayers can use tax software or IRS Free File to calculate credits automatically. IRS Free File is available if AGI is ≤ $73,000.

That threshold matters because many of the taxpayers most likely to qualify for the Earned Income Tax Credit or the Additional Child Tax Credit also fall into the income range for free filing help. For them, the combination of filing software and automatic credit calculations may remove some of the friction that keeps returns from getting filed.

The IRS also urged electronic filing, paired with direct deposit, as the fastest way to receive money owed. For taxpayers waiting on a refund, speed can depend not only on whether they file but how they file.

Even then, not every refund arrives immediately. The agency said taxpayers should expect delays for Earned Income Tax Credit and Additional Child Tax Credit refunds until mid-February, and the delay affects the entire refund.

That timing warning matters because households often focus on the credit amount and not the refund schedule. A filer may qualify for a larger payment through the Earned Income Tax Credit or Additional Child Tax Credit, but still need to wait longer than someone claiming other items on a return.

The IRS said taxpayers can check basic eligibility through the IRS Interactive Tax Assistant on irs.gov. That step can help people sort through changing income limits, student status, dependency rules and filing status without assuming they are ineligible.

Annual adjustments remain part of the picture. The agency said amounts and eligibility for these credits adjust each year, so taxpayers should verify whether they qualify for the 2025 tax year rather than rely on an earlier return.

That is especially true for the American Opportunity Tax Credit, where student status and modified AGI shape eligibility, and for the Additional Child Tax Credit, where age, dependency and SSN rules apply. It also matters for the Earned Income Tax Credit, which changes with income, filing status and family size.

Some of the rules will change again for later filings. The IRS warning said enhancements from the One, Big, Beautiful Bill apply to some credits in 2026 filings.

That means a taxpayer’s 2025 return and 2026 return may not work the same way, even when family circumstances appear similar. The agency’s message was to verify personal eligibility each year because rules vary by year, income and status.

For non-filers with older returns still missing, the three-year clock adds pressure. A person who qualified for the Earned Income Tax Credit, Additional Child Tax Credit, American Opportunity Tax Credit or a refund of withheld wages cannot wait indefinitely and still expect payment.

The IRS warning ultimately turned on a simple point: people who think they have nothing to file may still have money to claim. For millions of households, filing a return is not about paying tax but about collecting refunds already available under the law.
