8.5 Earned Income Tax Credit (EITC)
Key Takeaways
- For 2025, maximum EITC ranges from $649 (no children) to $8,046 (3+ children); investment income limit is $11,950
- Earned income includes wages, salaries, tips, and net SE income — NOT interest, dividends, unemployment, or Social Security
- Qualifying child must meet relationship, age, residency, and joint-return tests; workers without qualifying children must be age 25–64
- MFS filers are never eligible. Every individual (filer, spouse, qualifying children) needs a valid Social Security Number issued for employment; ITINs do not qualify
- Paid preparers must complete Form 8867 due diligence; the §6695(g) penalty is $600 per failure for 2025 returns (per credit/HoH claim)
Earned Income Tax Credit (EITC) Overview
The EITC is the most important refundable credit in the tax code — it can reduce tax liability below zero and produce a refund. The 2025 figures below come from Rev. Proc. 2024-40; OBBBA did not change EITC mechanics for 2025. The EA exam heavily tests EITC eligibility, income limits, due diligence, and disallowance rules.
2025 EITC Maximum Credit Amounts and Income Limits
| Qualifying Children | Maximum Credit | Single/HoH/QSS AGI Limit | Married Filing Jointly AGI Limit |
|---|---|---|---|
| 0 children | $649 | $19,104 | $26,214 |
| 1 child | $4,328 | $50,434 | $57,554 |
| 2 children | $7,152 | $57,310 | $64,430 |
| 3+ children | $8,046 | $61,555 | $68,675 |
Investment Income Limit: For 2025, you cannot claim EITC if investment income exceeds $11,950 (up from $11,600 in 2024). Investment income includes:
- Taxable interest
- Tax-exempt interest
- Dividends
- Net capital gain income
- Royalties and rental income from personal property
- Passive activity income
What Qualifies as Earned Income?
Earned Income INCLUDES:
| Income Type | Details |
|---|---|
| Wages, salaries, tips | Box 1 of W-2 (tips remain reportable even though OBBBA allows an above-the-line tip deduction) |
| Net self-employment income | Schedule C profit minus 1/2 SE tax |
| Union strike benefits | Payments while on strike |
| Disability benefits | Only if received BEFORE minimum retirement age |
| Nontaxable combat pay | Taxpayer may ELECT to include as earned income |
Earned Income DOES NOT Include:
| Income Type | Why Excluded |
|---|---|
| Interest and dividends | Investment income |
| Social Security benefits | Not from current work |
| Unemployment compensation | Replacement income |
| Child support | Not taxable income |
| Alimony received | Not earned |
| Pension/retirement income | Not current earnings |
| Workers' compensation | Not taxable |
| Welfare/TANF | Not earned |
Combat Pay Election: Active-duty military in combat zones receive nontaxable combat pay. Taxpayers may ELECT to include it in earned income for EITC purposes if it increases the credit.
OBBBA tip / overtime deductions and EITC: The new above-the-line deductions for qualified tips ($25K cap) and FLSA overtime premium ($12,500 single / $25,000 MFJ cap) reduce AGI but do not reduce the amount of earned income used to compute EITC. Tips and overtime are still earned income for EITC purposes.
EITC Qualifying Child Rules
The ARRJ Tests
| Test | Requirement |
|---|---|
| Age | Under 19 at year-end, OR under 24 if a full-time student, OR permanently and totally disabled (any age) |
| Relationship | Your child, stepchild, adopted child, foster child, sibling, step-sibling, or descendant of any of these |
| Residency | Lived with you in the U.S. for MORE THAN HALF the year |
| Joint Return | Child did not file a joint return (except solely to claim a refund) |
Important Notes:
- No support test for EITC (unlike dependency)
- Child must be YOUNGER than the taxpayer (or spouse)
- "U.S." means the 50 states and D.C., NOT U.S. territories like Puerto Rico or Guam
- Temporary absences (school, medical care, military) count as time living with you
Tiebreaker Rules
If more than one person claims the same child:
- Parent wins over non-parent
- Parent with longer residency wins over other parent
- Parent with higher AGI wins if residency is equal
- Higher AGI wins if neither is a parent
EITC Without Qualifying Children
2025 Requirements for Childless Workers:
| Requirement | Details |
|---|---|
| Age | At least 25 but under 65 at end of tax year |
| Residency | Main home in the U.S. for more than half the year |
| Dependency | Cannot be claimed as a dependent on another return |
| Qualifying child of another | Cannot be the qualifying child of someone else |
For MFJ filers, only ONE spouse needs to meet the age requirement.
2025 Limits Without Qualifying Children:
- Maximum credit: $649
- Single/HoH AGI limit: $19,104
- MFJ AGI limit: $26,214
Filing Status and Citizenship Requirements
Filing Status Restrictions
| Filing Status | EITC Eligible? |
|---|---|
| Single | Yes |
| Head of Household | Yes |
| MFJ | Yes |
| QSS | Yes |
| Married Filing Separately | NO — never eligible (no exceptions under current law) |
SSN and Citizenship Requirements
- Valid SSN required for the taxpayer, spouse (if MFJ), and every qualifying child — issued by the due date of the return (including extensions)
- The SSN must be valid for employment (not one issued only to receive benefits)
- ITINs do NOT qualify for any portion of EITC
- Nonresident aliens at any time during the year cannot claim EITC (exception: NRA who elects under §6013(g)/(h) to be treated as resident alien spouse on a joint return)
Tax Preparer Due Diligence Requirements
Form 8867 — Paid Preparer's Due Diligence Checklist
Paid preparers must complete and submit Form 8867 for every return claiming:
- Earned Income Tax Credit (EITC)
- Child Tax Credit (CTC) / ACTC / ODC
- American Opportunity Tax Credit (AOTC)
- Head of Household filing status
The Four KDCR Due Diligence Requirements
| Requirement | What It Means |
|---|---|
| K — Knowledge | Know the law, ask appropriate questions, do not ignore information |
| D — Document | Complete Form 8867 for each covered claim |
| C — Compute | Properly calculate the credit (use applicable worksheets) |
| R — Retain | Keep records for 3 years from the later of: due date, date filed, or date presented to taxpayer |
Due Diligence Penalty
The penalty for failing to meet due-diligence requirements under §6695(g) is $600 per failure for returns filed in 2025 (inflation-adjusted from the original $500). If a preparer fails diligence on all four covered items (EITC, CTC/ACTC/ODC, AOTC, HoH) on one return, the total penalty is $600 × 4 = $2,400.
Other consequences:
- Referral to the IRS Office of Professional Responsibility
- Possible injunction barring preparation of returns
- IRS "knock-and-talk" visits and preparer compliance audits
EITC Disallowance Rules
| Reason for Denial | Ban Period | Form to Reclaim |
|---|---|---|
| Math/clerical error | No ban | None |
| Other reasons (not fraud/reckless) | None, but Form 8862 required | Form 8862 |
| Reckless or intentional disregard | 2 years | Form 8862 after ban |
| Fraud | 10 years | Form 8862 after ban |
Form 8862 — Information to Claim Certain Credits After Disallowance
Required when EITC (or CTC/AOTC/ODC) was disallowed for any reason other than a math/clerical error. The taxpayer must demonstrate that all eligibility tests are now met.
Schedule EIC
When EITC is claimed with qualifying children, attach Schedule EIC to Form 1040, reporting for each child: name, SSN, year of birth, relationship, months lived with taxpayer, student status, and disability status.
How EITC Works: Phase-In and Phase-Out
- Phase-in — credit increases as earned income rises
- Plateau — credit stays at maximum
- Phase-out — credit decreases as income continues to rise
- Zero credit — once income exceeds the threshold
This design rewards work at low earnings levels and targets the largest benefits to working families with children.
