This calculator estimates your 2026 federal Earned Income Tax Credit (EITC) — a refundable credit for working people with low to moderate income. It applies the official rates and thresholds by number of qualifying children.
How it works
The EITC phases in with earned income, plateaus at a maximum, then phases out based on the greater of earned income and AGI:
phaseIn = min(earnedIncome * rate, maxCredit)
income = max(earnedIncome, AGI)
credit = max(0, phaseIn - max(0, income - phaseStart) * phaseRate)
The 2026 parameters by qualifying children are: no children — 7.65% rate, $649 max, phase-out from $10,620; one child — 34% rate, $4,328 max, 15.98% phase-out from $23,350; two children — 40% rate, $7,152 max, 21.06% phase-out from $23,350; three or more — 45% rate, $8,046 max, 21.06% phase-out from $23,350 (single/HoH starts).
Example
A single parent with two children earning $20,000 (AGI also $20,000): the phase-in is 20,000 * 40% = $8,000, capped at the $7,152 maximum. Income of $20,000 is below the $23,350 phase-out start, so there is no reduction. The estimated EITC is the full $7,152.
Notes
Estimate only — not tax advice. Uses 2026 EITC rates and maximums by number of qualifying children with the single/head-of-household phase-out starts; married-filing-jointly thresholds are higher. Eligibility also depends on investment-income limits, valid Social Security numbers, and filing status that this tool does not verify. Confirm with the IRS at irs.gov.
