What the EITC is worth in 2025, at a glance
0 qualifying children: max credit $632, AGI limit $18,591 single / $25,511 MFJ, minimum age 25, maximum age 64.
1 qualifying child: max credit $4,213, AGI limit $49,084 single / $56,004 MFJ.
2 qualifying children: max credit $6,960, AGI limit $55,768 single / $62,688 MFJ.
3 or more qualifying children: max credit $7,830, AGI limit $59,899 single / $66,819 MFJ.
Investment income limit for all categories: $11,950. Exceed that and the EITC is lost regardless of earned income.
Real example — $28,000 earner, single parent, 2 kids
Earned income: $28,000. Filing status: head of household. Two qualifying children, ages 8 and 11. Investment income: $140 (savings interest).
EITC calculation: credit phases in at 40% of earned income up to $17,400 — capping at $6,960. From $22,720 to $55,768 the credit is flat, then phases out. At $28,000 the credit is still at the full $6,960. Combined with the $2,000 Child Tax Credit × 2 = $4,000, total credits on this return: $10,960. On federal tax of maybe $1,200, that's a refund of roughly $9,760.
Why so many eligible families miss the EITC
The IRS estimates 20% of eligible households don't claim the EITC — leaving billions unclaimed every year. The most common reasons: (1) not earning enough to normally file, so they skip filing entirely; (2) a spouse died or left and the remaining filer doesn't know HoH rules; (3) a new kid in the household (birth, adoption, foster) that the filer forgets to claim; (4) using a non-free filing service that doesn't flag the credit.
Even if you owe zero tax, file. The EITC is refundable — you get a check for the full amount. The IRS Free File program supports it at zero cost if AGI is under $79,000.
What counts as a 'qualifying child'
Four tests, all must pass:
Relationship: your child, stepchild, foster child, sibling, half-sibling, or descendant of any of those (grandchild, niece, nephew).
Age: under 19 at year-end, or under 24 if a full-time student for at least 5 months, or any age if permanently disabled.
Residency: lived with you in the US more than half the year.
Joint return: child isn't filing a joint return (unless only to claim a refund).
The child must have a valid SSN — ITINs don't work for the EITC. Foster children must be placed by a recognized agency. Shared-custody situations: only one parent can claim the EITC for a given child in a given year; tiebreakers are in IRS Publication 596.
EITC fraud risk and audit protection
The IRS audits EITC returns at a higher rate than other returns with similar income — roughly 0.8% of EITC returns vs 0.2% overall. Most flagged returns aren't fraud; they're mistakes: claiming a child who didn't actually live with you, or claiming self-employment income at a level that maximizes the EITC (common fraud pattern called "Schedule C optimization").
Defenses: keep school records showing the child's address, lease or utility bills in your name, and contemporaneous daycare receipts. For self-employed filers, keep invoices, bank deposits matching claimed income, and mileage logs. Audit paperwork requests are mailed (CP75 notice); respond within 30 days or the credit is disallowed and clawed back.
How to claim the EITC on your return
File Form 1040 with Schedule EIC attached if you have qualifying children. Schedule EIC wants name, SSN, year of birth, and relationship for each child. If you're self-employed also file Schedule C and SE. If the IRS previously disallowed your EITC claim in a prior year, you must file Form 8862 to claim it again.
Due to the PATH Act, the IRS cannot issue EITC refunds before mid-February regardless of when you file. Filing January 27 vs February 12 makes no difference in when the money arrives — expect deposits around February 27 for early filers.
