Somewhere in the U.S. right now, a warehouse worker, a home health aide, or a couple splitting retail shifts is owed thousands of dollars by the federal government and does not know it. According to the most recent IRS participation data, roughly 19.2 percent of workers eligible for the Earned Income Tax Credit did not claim it in tax year 2022. That is about one in five qualifying households walking away from a refundable credit worth up to $8,046 for families with three or more children.
For a single parent earning $40,000 a year, that unclaimed credit could equal more than a full month’s take-home pay. But the EITC is not automatic. Workers must file a federal return and explicitly claim it. Those who skip filing, or who file but overlook the credit, receive nothing.
How much money is at stake
The IRS adjusts EITC amounts each year for inflation under Internal Revenue Code Section 32. For tax year 2025, the return most filers are preparing during the spring 2026 filing season, the maximum credits are:
- Three or more qualifying children: up to $8,046
- Two qualifying children: up to $7,152
- One qualifying child: up to $4,328
- No qualifying children: up to $649
The Internal Revenue Bulletin 2024-45, which contains Rev. Proc. 2024-40, confirms the inflation-adjusted parameters that apply to tax year 2025 returns. Because the credit is fully refundable, filers whose EITC exceeds their tax liability receive the difference as a cash refund. That makes it one of the federal government’s most direct tools for supplementing low-wage earnings.
The EITC can also be claimed alongside the Child Tax Credit on the same return, which can significantly increase a family’s total refund. Each credit has its own eligibility rules and income phase-outs, though, so qualifying for one does not guarantee qualifying for the other.
State-level supplements worth checking
More than 30 states, plus the District of Columbia, offer their own earned income tax credits that piggyback on the federal EITC. These state supplements are claimed on the state return and typically equal a fixed percentage of the federal credit amount. The percentage varies widely. California’s CalEITC, for example, operates as a standalone state credit with its own income limits, while states like New York and New Jersey set their credits at roughly 30 percent or more of the federal amount. A handful of states make their version refundable even when the filer has no state income tax liability; others offer only a nonrefundable offset.
Workers who qualify for the federal EITC should check whether their state offers a matching credit. Failing to file a state return can mean leaving additional money unclaimed on top of the federal benefit.
Who qualifies and who is missing out
Eligibility hinges on having earned income from a job or self-employment and falling below income thresholds that vary by household size. The IRS spells out the full rules on its Earned Income Tax Credit page, but the broad strokes are straightforward: workers must have a valid Social Security number, cannot file as “married filing separately,” and must meet residency and age requirements for any children they claim.
The 19.2 percent non-claiming rate comes from a linked analysis that matches Census Bureau American Community Survey responses with actual IRS filing records. That methodology has been the federal government’s standard approach for estimating EITC take-up for years and remains the most authoritative measure available.
Certain groups are especially likely to leave the credit unclaimed. The IRS EITC Awareness Day campaign, now in its 20th year, flags workers whose marital or parental status recently changed, people who earned income for the first time, and those who simply do not know the credit exists. Workers without dependents, who qualify for a much smaller credit, may also skip filing because they assume the refund is not worth the effort.
Why eligible workers do not claim it
No single federal study ranks these barriers by impact, but the obstacles that surface most often in IRS outreach materials and advocacy research fall into clear categories:
- Not filing at all. Workers whose income falls below the standard filing threshold may not realize they still need to submit a return to receive the EITC.
- Unfamiliarity with the credit. The EITC is not withheld or applied automatically. If a filer or their tax preparer does not know to claim it, the credit goes uncollected.
- Cost of tax preparation. Paid preparers can charge fees that eat into a small refund, discouraging some low-income workers from filing at all.
- Language barriers and limited access. Workers with limited English proficiency or unreliable internet access face additional hurdles navigating the filing process.
- Distrust of the tax system. Some eligible workers avoid filing out of concern about audits or interactions with the IRS. That worry is not unfounded: research from the Treasury Inspector General for Tax Administration and reporting by ProPublica have documented that EITC returns are audited at rates disproportionately higher than returns from many higher-income filers.
The relative weight of each barrier has not been rigorously quantified in any published federal study, a gap that makes it harder to know which interventions would close the most ground.
Documents needed and how long the refund takes
Before sitting down to file, workers should gather the following:
- Social Security numbers for themselves, their spouse (if filing jointly), and every qualifying child listed on the return.
- W-2 forms from each employer for the tax year, showing wages and withholding.
- 1099 forms for any freelance, gig, or self-employment income.
- Records of other earned income, such as tips or cash wages not reported on a W-2.
- A valid bank account and routing number for direct deposit, which is the fastest way to receive the refund.
- Prior-year tax return (if available), which can speed up the process and help verify identity.
Under the Protecting Americans from Tax Hikes (PATH) Act, the IRS cannot issue refunds that include the EITC before mid-February, even if the return is filed the day the season opens. For returns filed electronically with direct deposit, the IRS generally delivers EITC refunds within 21 days after the mid-February hold lifts. Paper-filed returns or those requesting a mailed check can take six weeks or longer. Filers can track their status using the “Where’s My Refund?” tool on the IRS website or through the IRS2Go mobile app.
Free filing options that remove the cost barrier
The IRS promotes several no-cost paths to filing designed to reduce the obstacles listed above:
- IRS Free File: Taxpayers who meet income requirements can prepare and e-file their federal returns at no charge through commercial software partners listed on the IRS website.
- IRS Direct File: A newer option that lets eligible taxpayers file directly with the IRS without using a third-party product.
- Volunteer Income Tax Assistance (VITA): Community-based sites staffed by IRS-certified volunteers offer free tax preparation for workers earning roughly $67,000 or less, people with disabilities, and those with limited English proficiency.
- Tax Counseling for the Elderly (TCE): Similar to VITA but focused on taxpayers age 60 and older, with particular attention to pension and retirement-related questions.
Workers can locate the nearest VITA or TCE site by using the IRS site locator tool or calling 800-906-9887. The filing season for tax year 2025 returns opened in late January 2026, and the standard deadline is April 15, 2026. Workers who miss that date can still file a late return to claim the EITC for up to three prior tax years.
How to find out if you qualify before the April 2026 deadline
The pattern is well established and the stakes are real: every filing season, a significant share of eligible workers leaves money unclaimed that could reshape a household’s finances. For a family with three children, the maximum $8,046 credit could cover several months of groceries, a security deposit on a safer apartment, or the start of an emergency fund that did not exist before.
Workers who are unsure whether they qualify can use the IRS EITC Assistant, a free online tool that walks through eligibility questions in a few minutes. Those who earned income in 2025 but have not yet filed still have time before the April 15, 2026 deadline. And anyone who missed the credit in earlier years can file amended or late returns going back to tax year 2022 to recover what they are owed. The money does not disappear on its own, but it will not show up in a bank account until someone files the paperwork to claim it.
