Earned Income Tax Credit (2026)

What the Earned Income Tax Credit does

The Earned Income Tax Credit (EITC) is a refundable credit for low-to-moderate income workers. Refundable means it can pay you even when income tax liability is zero—unlike many credits that only offset tax. The credit rises with earned income up to a plateau, then phases down as income increases. More qualifying children generally mean higher maximum credits and wider income ranges.

This calculator applies 2026 IRS parameters to your earned income, AGI, filing status, and child count. It does not determine whether a specific child meets relationship, residency, and age tests—that is your responsibility with Publication 596.

2026 planning context

EITC sits alongside other 2026 inflation-adjusted items: standard deduction $16,100 single, $24,150 head of household, $32,200 joint; 401(k) limit $24,500; IRA limit $7,500. EITC phaseouts are independent tables—not simple percentages of the standard deduction.

Investment income caps disqualify filers with too much passive income even when wages are modest. Dividends, interest, and capital gains count toward that cap—model investment sales in the capital gains tax calculator if you are near limits.

Who might qualify (conceptually)

• Workers with W-2 wages and/or modest Schedule C profit
• Head of household or joint filers with qualifying children
• Childless workers at older minimum ages (see IRS age rules for 2026)

Nonresident aliens, filers without valid SSNs for work (except certain married joint cases), and high investment income households are generally out. Married filing separately is usually barred.

How to use the calculator

Step 1 — Enter earned income honestly

W-2 wages plus net self-employment profit are the core. Use net Schedule C after expenses, not gross 1099 receipts.

Step 2 — Match AGI

AGI includes earned income plus other items minus above-the-line adjustments. EITC tests both earned income and AGI—whichever is higher in the phaseout can control.

Step 3 — Set filing status and child count

Qualifying child rules require relationship, age, residency, and joint return tests. The calculator assumes children you count are qualifying—do not inflate counts.

Step 4 — Read refund impact

Pair with the tax refund estimator to see how EITC stacks with withholding. Pair with the federal income tax calculator for ordinary tax before credits.

Phaseout mechanics

Think of three zones: income too low for maximum credit (credit rises with earnings), plateau at maximum credit, and phaseout where credit falls as income rises until it hits zero. The slopes and plateaus differ by child count. A $500 raise near the phaseout cliff can reduce EITC by more than $500—marginal “tax rates” including credit loss can exceed nominal brackets.

Self-employment and EITC

Schedule C profit counts as earned income for EITC but also triggers self-employment tax. SE tax reduces net refund even when EITC is large. The self-employment tax calculator and quarterly estimated tax calculator help with payment timing so EITC refunds are not eaten by April SE tax bills.

Worked example (head of household, one child, 2026)

Suppose $28,000 W-2 wages, $28,000 AGI, one qualifying child, head of household filing:

• Ordinary income tax after $24,150 standard deduction may be modest
• EITC may be near the one-child maximum for 2026 parameters—run exact inputs above
• Combined refund includes withheld tax plus refundable EITC minus any SE or other liabilities

Increase wages to $55,000 and the credit may phase down sharply while marginal brackets rise—dual effects worth modeling before overtime or extra shifts.

Common mistakes

• Claiming children who fail residency or relationship tests
• Using gross 1099 instead of net Schedule C profit
• Ignoring investment income disqualification limits
• Filing MFS when joint filing is required for EITC
• Assuming EITC replaces CTC—many households claim both with separate rules

Interaction with other credits

Child tax credit and dependent credits use different income tests. Use the child tax credit calculator alongside this tool. EITC also interacts with state EITC clones in many states—this page is federal-only.

Withholding and EITC

Large EITC at filing time often means over-withholding during the year if W-4 did not account for credits. That is not harmful financially but affects cash flow. Tune W-4 with the W-4 withholding calculator once you understand recurring EITC eligibility.

Documentation if IRS asks

Keep school records, medical records, lease agreements, and custody documents supporting residency. Keep pay stubs and Schedule C books for income. EITC due diligence rules apply to paid preparers; self-preparers should hold the same facts.

Related tools

Compare paycheck withholding in the paycheck calculator. Model HSA and 401(k) AGI effects in the 401(k) calculator and HSA calculator. Check itemized vs standard paths in the standard vs itemized calculator—most EITC households take the standard deduction.

Childless EITC and age rules

Workers without qualifying children face lower maximum credits and tighter age windows (generally 25–64 for childless EITC under current rules—confirm Publication 596 for 2026). Do not assume EITC is only for parents; childless filers near phaseout cliffs still benefit from modeling exact credit amounts before changing work hours.

Split households and custody

Only one return may claim a qualifying child for EITC when parents live apart. Tiebreaker rules favor the parent with whom the child lived longer during the year, then higher AGI. Mis-matched claims between ex-spouses trigger IRS adjustments. Document overnight stays and school address when custody is shared.

Head of household status with a qualifying child unlocks the $24,150 standard deduction in 2026—often the right filing status for single parents even when EITC is the main credit in play.

Schedule C losses and EITC

A side business loss reduces earned income and can shrink or eliminate EITC even when W-2 wages alone would qualify. Before you accelerate expenses to “save tax,” run the loss scenario here—credit phaseouts can cost more than the SE tax savings. The self-employment tax calculator shows the payroll-tax side separately.

Investment income near the disqualification limit deserves the same caution: a modest taxable dividend can wipe EITC entirely while wages still look eligible on first glance.

Sources and methodology

EITC maximums, phaseouts, and investment income limits follow IRS 2026 inflation adjustments (Rev. Proc. 2025-32 and related newsroom summaries). Results are educational estimates with calculation traces—not determinations of child eligibility or filing status. Verify with IRS Publication 596 and current instructions before claiming the credit.
