The formulas
- Credit = lesser of (credit rate x earned income) and the maximum credit
- Rates: 7.65% (none), 34% (one), 40% (two), 45% (three or more)
- Reduction = phase-out rate x (greater of AGI or earned income - phase-out threshold)
- Phase-out rates: 7.65%, 15.98%, 21.06%, 21.06%. No credit if investment income exceeds $12,200
How it works
The earned income credit rises with earnings to a maximum, stays there, and then phases out as the greater of AGI or earned income rises. The 2026 maximums, thresholds and completed phase-out amounts come from Rev. Proc. 2025-32, and the percentages are in section 32(b).
Taxpayers with no qualifying child must be at least 25 and under 65 at the end of the year under section 32(c). Investment income above $12,200 cancels the credit for 2026. The Form 1040 instructions carry the IRS lookup tables; this tool computes the credit directly from the section 32(b) rates and the amounts above.

Common questions
Which phase-out column applies if I am married filing separately?
Rev. Proc. 2025-32 says the non-joint column also applies to married taxpayers who file apart and meet the separated spouse rules in section 32(d).
What does three or more children change?
It uses a 45 percent credit rate and a $8,231 maximum credit for 2026.
Does this check the other EITC rules?
No. Residency, relationship, Social Security numbers and filing status tests are not checked here.
