The Earned Income Tax Credit is the country's largest cash program for working families — worth up to $8,046 for a family with two kids in 2025, fully refundable, and famously under-claimed: roughly 20% of eligible workers leave it on the table every year, mostly people whose incomes are low enough that they aren't required to file at all. This tool computes your credit through the EITC's trapezoid geometry — phase-in, plateau, phase-out — and tells you exactly where you sit on it.

The 2025 Numbers

ChildrenMax creditIncome limit (single)Income limit (married)
0$649~$19,100~$26,200
1$4,328~$50,400~$57,550
2$8,046~$61,550~$68,650
3+$9,081~$66,450~$73,550

How the Trapezoid Works

  1. Phase-in: from the first dollar earned, the credit grows at 34–45 cents per dollar (with kids) — a genuine wage subsidy; working more always pays more here.
  2. Plateau: the maximum credit holds across a middle band.
  3. Phase-out: above ~$23,350 ($30,470 married), the credit shrinks ~16–21 cents per extra dollar — a hidden marginal-rate bump worth knowing, but never a reason to earn less: you always net more by earning more.

Eligibility Beyond Income

  • Earned income required: wages or self-employment profit — investment income, benefits and retirement income don't count (and investment income above $11,950 disqualifies entirely).
  • Qualifying children: under 19 (24 if full-time students), living with you over half the year — broader than the CTC's rules; grandchildren and siblings can qualify.
  • No kids? Still real: workers 25–64 get up to $649 — small, but it's a free filing away.
  • SSNs required for you, spouse and qualifying children; married-filing-separately generally disqualifies.
  • Self-employed count fully — gig workers and freelancers qualify on net profit (and the phase-in makes reporting income genuinely profitable at low levels, a rare tax fact).

Why a Fifth of It Goes Unclaimed

The eligible-but-unclaimed are concentrated among people below the filing threshold (~$15,000 single) who owe nothing and therefore don't file — not realizing the EITC would pay them thousands. Others: new parents who didn't update their filing, workers whose income dropped mid-career, and grandparents raising grandchildren. The fix is always the same: file a return (free via IRS Free File at these incomes), and you can retroactively claim up to three prior years.

How to Use the Tool

  1. Enter earned income, qualifying children, filing status and any investment income.
  2. Read the credit, your zone on the curve, and the parameter table for your family size.
  3. If you know someone in the phase-in zone who doesn't file — tell them. It's the highest-yield tax advice that exists.

Frequently Asked Questions

Is the EITC really fully refundable?

Yes — it's paid out regardless of tax owed; most EITC dollars arrive as refund checks. By law, EITC refunds are held until mid-February for fraud screening — the annual timing question answered.

Does unemployment or Social Security count as earned income?

No — only wages, salary, tips and self-employment profit. Benefit income neither adds to the credit nor disqualifies (except investment income above the $11,950 cap).

Can I get EITC and the Child Tax Credit together?

Absolutely — they stack, along with the child-care credit. A single parent with two kids earning $28,000 can receive $10,000+ combined between EITC and CTC refundability — run both tools.

I'm a gig worker with cash income — should I report it?

Yes, doubly so: it's legally required AND, in the phase-in zone, each reported $1,000 of profit adds ~$340–450 of EITC (minus ~$150 SE tax) — reporting income at low levels literally pays. Under-reporting also shrinks future Social Security benefits.

What if my income changed drastically this year?

EITC uses this year's income only — a layoff year or income drop can make a normally-ineligible family eligible for one year. Check eligibility any year income falls; it's the most-missed one-time claim.

Can I claim prior years I missed?

Yes — file or amend up to 3 years back (refund statute). A family discovering eligibility can recover $15,000+ across three amended returns. Free tax clinics (VITA) handle exactly this.

Is my information private?

Yes — every figure computes locally in your browser.

The EITC is the rare program that rewards work, stacks with everything, and pays retroactively — its only failure mode is not filing. Check your number, check your years, and pass the tool to the person you know who's leaving it unclaimed.
