Earned Income Tax Credit (EITC) for CPAs: Eligibility Rules, 2025 Limits, and §6695(g) Due Diligence
The Earned Income Tax Credit is one of the largest refundable credits in the federal tax code — worth up to $8,046 for a client with three or more qualifying children in TY2025 — and one of the most frequently misapplied. For CPAs, EITC carries a dual obligation: accurate application of a multi-layered eligibility test and strict compliance with the §6695(g) preparer due diligence requirements that can result in out-of-pocket penalties for the firm if not followed. EITC overclaims are also among the IRS's highest audit priorities, making documentation discipline essential for both clients and preparers.
TY2025 EITC Income Limits and Maximum Credits
The EITC is a refundable credit under IRC §32 designed to supplement income for working individuals and families below specified thresholds. The credit phases in with earned income, reaches a plateau, and then phases out as adjusted gross income (or earned income, whichever is greater) rises above defined limits.
For TY2025 (returns filed in 2026), IRS Rev. Proc. 2024-61 sets the following maximum credits and income limits:
| Qualifying Children | Max Credit | Max AGI (Single/HH) | Max AGI (MFJ) |
|---|---|---|---|
| 0 | $649 | $19,104 | $26,214 |
| 1 | $4,328 | $50,434 | $57,554 |
| 2 | $7,152 | $57,310 | $64,430 |
| 3 or more | $8,046 | $61,555 | $68,675 |
The AGI limit and the earned income limit are tested separately — a client fails the income test if either their AGI or their earned income (whichever is greater) exceeds the threshold for their filing status and number of qualifying children. Married filing separately taxpayers are categorically ineligible for EITC under IRC §32(d).
Investment income is capped at $11,950 for TY2025 (IRS Rev. Proc. 2024-61). A client whose investment income — including interest, dividends, net capital gain, and passive activity income — exceeds this limit is entirely disqualified regardless of earned income or filing status.
What Counts as Earned Income Under IRC §32
EITC eligibility depends on "earned income," a defined term under IRC §32(c)(2) that is narrower than total gross income. Earned income includes:
- Wages, salaries, and tips reported on Form W-2, including union strike benefits
- Net earnings from self-employment (Schedule C or Schedule F net profit after deducting the deductible portion of self-employment tax)
- Statutory employee income reported in Box 1 of a W-2 with Box 13 checked
- Long-term disability payments received before reaching minimum retirement age under an employer plan
Earned income explicitly excludes:
- Social Security and railroad retirement benefits
- Pension and annuity income (including IRA distributions)
- Alimony (for divorce agreements executed before 2019, which still report alimony as income)
- Unemployment compensation
- Workers' compensation payments
- Child support
- Interest and dividends
- Net rental income or net passive activity income
- Income earned by a prison inmate for work performed for the prison
The most common practitioner error is treating gross self-employment receipts as earned income. EITC is calculated on net self-employment income after Schedule C deductions — including the deductible portion of SE tax under IRC §164(f). A client with $60,000 in gig income and $35,000 in deductible business expenses has net earned income of approximately $25,000, a materially different EITC computation than their gross receipts would suggest. For more on self-employment income reporting, see our guide to gig economy tax reporting.
Income from employment relationships also requires attention. If a client is misclassified as an independent contractor but is legally an employee, the earned income calculation and SE tax treatment change — see our analysis of worker classification under IRS rules for the factors the IRS uses to distinguish employees from contractors.
The Qualifying Child Test: Four Requirements, All Must Be Met
A qualifying child for EITC purposes requires satisfaction of four independent tests under IRC §32(c)(3). Failing any single test eliminates the child from EITC eligibility.
1. Relationship Test
The child must be the taxpayer's son, daughter, stepchild, foster child, sibling, half-sibling, stepsibling, or a descendant of any of these (e.g., grandchild, nephew, niece). The IRS does not require a blood relationship — a legally adopted child and a foster child placed by a licensed agency both qualify.
2. Age Test
At the end of the tax year, the child must be:
- Under age 19, or
- Under age 24 and a full-time student for at least five months during the year, or
- Any age if permanently and totally disabled (as defined under IRC §22(e)(3))
A child who is older than the taxpayer cannot be a qualifying child for EITC unless the taxpayer is permanently and totally disabled.
3. Residency Test
The qualifying child must have the same principal place of abode as the taxpayer for more than half the tax year. Temporary absences for school, vacation, illness, or detention count as time living with the taxpayer. A child born or who died during the tax year satisfies the residency test if the home was the child's home for the entire period the child was alive.
4. Joint Return Test
The child cannot be claimed as a qualifying child if the child files a joint return with a spouse — unless the joint return is filed solely to claim a refund of withheld taxes or estimated tax (i.e., neither the child nor the child's spouse would have a tax liability requiring a return).
Tiebreaker rules apply when the same child qualifies under two taxpayers' returns. Under IRC §32(c)(1)(C), the child is treated as the qualifying child of the parent. If both parents claim the child and they did not live together, the IRS assigns the child to the parent with whom the child resided for more nights. If nights are equal, the higher-AGI parent wins the tiebreaker. A non-parent can only use the child for EITC if no parent claims the child and the non-parent's AGI exceeds that of any parent of the child.
Childless EITC: Eligibility Without a Qualifying Child
Taxpayers without a qualifying child can still claim EITC if they meet additional requirements under IRC §32(c)(1)(A)(ii). For TY2025:
- Age: Must be at least 25 and under 65 as of the end of the tax year
- Residency: Must have lived in the United States for more than half the year
- Not claimed as a dependent: The taxpayer cannot be the dependent of another taxpayer
- Income: Must have earned income and AGI below $19,104 (single) or $26,214 (MFJ)
Special rule for former foster youth and homeless youth: A taxpayer who was in foster care on or after age 14 and has left the foster care system, or who is certified by a qualified organization as a homeless youth, is eligible for childless EITC beginning at age 18 rather than 25. This rule was made permanent by the Consolidated Appropriations Act of 2023. The $649 maximum credit for childless filers provides modest relief but can be meaningful for low-income young adults meeting these criteria.
The American Rescue Plan Act of 2021 temporarily expanded childless EITC eligibility to all taxpayers ages 19–64 for TY2021 only. That expansion has expired and does not apply to TY2025 returns.
IRC §6695(g): Due Diligence Requirements for Paid Preparers
Any paid return preparer who prepares a return or claim for refund claiming the EITC must comply with the due diligence requirements under IRC §6695(g) and the implementing regulations at Treas. Reg. §1.6695-2. The same due diligence framework applies to the Child Tax Credit/Additional Child Tax Credit, the American Opportunity Tax Credit, and head of household filing status.
Failure to comply results in a penalty of $100 per failure, indexed for inflation annually. For recent tax years, the penalty is approximately $545–$600 per failure per return (Rev. Proc. 2023-34 set $545 for TY2023; amounts adjust each year). If a preparer prepares 200 EITC returns without completing Form 8867 properly, the exposure is over $100,000 — an existential event for a small firm.
The four due diligence requirements:
1. Eligibility Checklist — Form 8867
Complete and submit Form 8867 (Paid Preparer's Due Diligence Checklist) with every return claiming EITC. The form asks whether the preparer obtained information to determine eligibility, whether the information appeared correct, and whether the computation followed IRS worksheets. Form 8867 must be completed even if it seems obvious the client qualifies.
2. Computation Worksheets
The preparer must use the worksheets in IRS Publication 596 or the equivalent tax software worksheet to compute the credit. The computation must be based on the information the client provided; the preparer cannot simply take the client's word that the credit is a certain amount.
3. Knowledge Requirement
The preparer must not know, or have reason to know, that any information used to determine eligibility is incorrect, inconsistent, or incomplete. Treas. Reg. §1.6695-2(b)(3) requires the preparer to ask additional questions when the information furnished appears incorrect, inconsistent, or incomplete. This is the "reasonable inquiries" standard — a preparer who is told a client has three qualifying children but knows the client has lived alone for years must probe further.
4. Record-Keeping Requirement
The preparer must retain copies of all documents the client provided, all eligibility questions asked and the client's answers, and the completed Form 8867 for three years from the later of the return due date or the date the return was filed. Records must be available for IRS inspection.
The IRS conducts preparer audits specifically targeting EITC compliance. A preparer identified as having systemic due diligence failures may face:
- Civil penalties under §6695(g)
- Enhanced scrutiny for all future filings
- Referral to the Office of Professional Responsibility for Circular 230 sanctions
- Injunction from preparing tax returns if violations are egregious

EITC Audit Risk: Common Triggers and Documentation
EITC claims carry the highest improper payment rate of any refundable credit in the federal tax code. The IRS estimates an overclaim rate of approximately 31–35% of all EITC claims, resulting in billions in annual improper payments. This makes EITC one of the most scrutinized line items in IRS examination programs — particularly through correspondence audits requesting documentation.
Common EITC audit triggers:
- Child not residing with taxpayer: The IRS matches Social Security records and school enrollment data. A child registered at a different address than the taxpayer raises immediate flags.
- Qualifying child age discrepancies: SSA records flag children who are 19+ and not claimed as full-time students.
- Multiple taxpayers claiming the same child: Common in split custody situations where one parent claims the child for income tax exemptions while the other claims EITC.
- Self-employment income fluctuations: Schedule C net income that is suspiciously optimized to maximize EITC — barely positive or exactly at the phase-in plateau — draws scrutiny.
- Year-over-year credit claim inconsistency: A client who never qualified for EITC suddenly claiming it after a major income drop warrants verification.
When an EITC client receives a CP75 or CP75A notice (audit of EITC claim), they must respond with documentation of each qualifying child's residency and relationship. Acceptable documentation includes school records, medical records, childcare records, landlord statements, and government assistance records. Coaching clients to retain this documentation at filing time — not six months later when a notice arrives — is a meaningful risk management step.
For a complete breakdown of which claims trigger IRS examination and how to build an audit-proof file, see our guide to IRS audit triggers and defense strategies.
EITC clients who are audited and denied may also receive a two-year ban (and in fraud cases a ten-year ban) from claiming EITC in subsequent years under IRC §32(k). This is an irreversible consequence of a fraudulent or reckless claim, making accurate original preparation critical.
Filing Status and Other Disqualifying Conditions
Beyond the earned income and qualifying child tests, several additional conditions can disqualify an otherwise eligible taxpayer:
- Married filing separately: Categorically ineligible under IRC §32(d). Advise clients on the cost of MFS before they elect it.
- Foreign income exclusion: Taxpayers who exclude income under IRC §911 (the foreign earned income exclusion) cannot claim EITC on that excluded income. If a client lives and works abroad and claims FEIE, their EITC is calculated only on income not excluded.
- No valid Social Security number: All individuals named on the EITC claim — taxpayer, spouse, and each qualifying child — must have a valid Social Security number (SSN) issued by the Social Security Administration that is valid for employment. Individual Taxpayer Identification Numbers (ITINs) do not qualify. Adoption taxpayer identification numbers (ATINs) are also insufficient for EITC purposes.
How EITC Interacts with Other Credits
EITC and the Child Tax Credit often apply to the same clients and use overlapping eligibility concepts but have distinct mechanics. The Child Tax Credit applies at higher income levels (phase-out begins at $200,000 single/$400,000 MFJ) and has a $2,000 per child credit amount for TY2025. A client can claim both credits for the same qualifying child — they are not mutually exclusive. See our guide to the Child Tax Credit 2025 income limits and ACTC refundability for the full analysis of that companion credit.
The Additional Child Tax Credit (ACTC) is the refundable portion of the Child Tax Credit and computes independently from EITC. Clients who qualify for both the EITC and ACTC will receive separate refundable credit amounts for each, subject to the separate income limits governing each credit.
Frequently Asked Questions
Can a client claim EITC if they have no qualifying children but had self-employment income that was a loss?
No. A net self-employment loss reduces earned income for EITC purposes. If a client's only earned income comes from a Schedule C business that had a net loss, their earned income for EITC is zero and they do not qualify — even for the childless credit. If the client also has W-2 wages, those wages count as earned income regardless of the Schedule C loss.
Does alimony received count as earned income for EITC?
For divorce agreements executed on or after January 1, 2019, alimony is neither included in the recipient's income nor deductible by the payer under the TCJA changes. For agreements executed before 2019 that have not been modified, alimony is still income — but not earned income. It does not count toward EITC and does not affect the investment income cap.
What happens if the IRS disallows EITC because a child was also claimed by another taxpayer?
Both taxpayers receive a notice. The IRS will ask each to establish their claim. The tiebreaker rules under IRC §32(c)(1)(C) determine which taxpayer's claim stands — parent over non-parent, and higher-AGI parent wins when both are parents. The losing taxpayer must repay the credit plus interest. If the return preparer failed to conduct required due diligence, the §6695(g) penalty applies even if the preparer acted in good faith on incorrect client information.
Are foster children placed by licensed agencies eligible qualifying children for EITC?
Yes. A child placed with a taxpayer by a licensed foster care agency qualifies under the relationship test as a "foster child." An informally placed child — where a friend or relative leaves a child with the taxpayer without any agency involvement — does not qualify as a foster child under the EITC relationship test.
Can a graduate student age 23 who is claimed as a dependent on their parents' return claim EITC?
No. A person who can be claimed as a dependent by another taxpayer cannot claim EITC for themselves. Being a full-time student under age 24 may satisfy the age test for someone else's qualifying child determination — but the student themselves cannot claim EITC while properly claimed as a dependent on another return.
What records must I retain as a preparer after filing an EITC return?
Retain: (1) a completed Form 8867, (2) the EITC worksheet used to compute the credit, (3) all documents the client provided to establish eligibility (copies or notation of what was reviewed), and (4) a record of any additional questions asked and the client's responses. These records must be kept for three years from the later of the return due date or the filing date.
Does the EITC phase out at the same rate for all filing statuses?
The income limits differ by filing status, but the phase-out rate is the same for single and MFJ taxpayers — only the threshold at which phase-out begins differs. Married filing jointly filers get a higher phase-out threshold (approximately $7,110 more for TY2025), reflecting the two-earner family income structure. The phase-out rate is 7.65% for childless EITC, 15.98% for one child, 21.06% for two children, and 21.06% for three or more children (rates are approximately calculated as the credit divided by the phase-out range).
If a client has both wages and a Schedule C loss, how is earned income computed for EITC?
Earned income is computed as the sum of all earned income items. Wages are always positive; a Schedule C net loss is a negative number that reduces earned income. If a client has $30,000 in W-2 wages and a $15,000 Schedule C net loss, their earned income for EITC is $15,000. The Schedule C loss cannot reduce earned income below zero — if the net result would be negative, earned income is treated as zero.
