Earned Income Tax Credit Calculator

What Is the Earned Income Tax Credit Calculator?

This tool estimates the federal Earned Income Tax Credit (EITC) using the latest full IRS table (tax year 2025, as published on irs.gov) -- credit rate, earned income amount, maximum credit, and phase-out threshold/rate -- for 0, 1, 2, or 3+ qualifying children. EITC rules are genuinely complex (with additional AGI, investment-income, and qualifying-child tests this simplified calculator doesn't fully model), and the dollar parameters change every tax year. Treat this as a starting estimate, not a substitute for the IRS's own EITC Assistant or a tax professional.

How to Use This Tool

Enter your earned income and number of qualifying children, and select your filing status. Your estimated EITC appears instantly.

How the Estimate Is Built

The tool uses a small parameter table with four rows, one each for 0, 1, 2, and 3 or more children, and separate values for Single / Head of Household and Married filing jointly. Each row has a credit rate, an earned income amount, a maximum credit, a phase-out threshold, and a phase-out rate. The calculation has three zones. In the phase-in zone the credit is your earned income times the credit rate, capped at the maximum. In the plateau it stays at the maximum, up to the phase-out threshold. Above the threshold the credit shrinks by the phase-out rate for each dollar of income over it, until it reaches zero. The number of children is rounded to a whole number and anything above three uses the three-child row.

The tool uses earned income for every zone, including the phase-out. The real rules can also look at AGI in the phase-out and apply an investment income limit, which is not modeled here.

Reading the Three Zones

• Phase-in: each extra dollar of earnings raises the credit, so a very low earner gets a small credit.
• Plateau: the credit sits at its maximum for a band of earnings.
• Phase-out: the credit drops as income grows, which is why the estimate can be zero for a higher earner even though the same person would get a credit at lower income.

Worked Examples (Hypothetical Numbers)

• Single, one child, earned income of 10,000: using the row for one child (rate 34%), 10,000 times 0.34 equals 3,400, which is under the row's maximum of 4,328. The estimate is 3,400.00.
• Single, one child, earned income of 15,000: 15,000 times 0.34 is 5,100, capped at 4,328, and 15,000 is below the phase-out threshold of 23,350, so the estimate is 4,328.00.
• Single, no children, earned income of 12,000: the credit would be 12,000 times 7.65%, capped at 649, so 649.00. The row's threshold of 10,620 is below 12,000, so the phase-out applies and the credit is 649 minus (1,380 times 0.0765), which is about 543.43.

The examples use the tax year 2025 figures built into the tool. Confirm the amounts for your year at irs.gov, since they change annually.

Step-by-Step Tips

• Enter earned income only: wages, self-employment net earnings, and similar. Investment income, unemployment benefits, and pensions are not earned income.
• Count only children who meet the IRS qualifying-child tests. The tool does not check.
• Pick the filing status you will use. Married filing separately is not part of this tool.
• If the result is zero, check whether your earned income is above the range for your number of children, or consider whether the rules have different limits for your situation.

Common Mistakes

• Entering AGI instead of earned income.
• Overstating the number of children by including someone who does not meet the residency or relationship tests.
• Forgetting that a tax return may need extra forms or schedules to claim a credit, and that mistakes can delay a refund.
• Treating the estimate as a promise. It depends on rules the tool only approximates.

Limits and When to Get Help

Eligibility has additional tests: Social Security number requirements, an investment income limit, residency rules, and special situations for people without children. If your household changed during the year, or a child could be claimed by more than one person, use the IRS EITC Assistant or a qualified tax preparer. Free tax assistance programs exist for eligible taxpayers, and the IRS website explains how to find them.
