Summary: The most common EITC errors are claiming a child who fails the tests, filing the wrong status when married, misreporting income, wrong or missing Social Security numbers, exceeding the income or investment limits, and claiming while filing separately. Consequences range from delayed refunds to repaying the credit with interest, filing Form 8862 to reclaim it, a 2-year ban for reckless disregard, and a 10-year ban for fraud.
The IRS is blunt about this: the EITC is complex, and a large share of claims contain errors. Some mistakes cost you the credit for a year. A few can lock you out for years. Here are the errors the IRS flags most often, and what happens when you make them.
This is the most common EITC error, in the IRS's own words. Usually it is the residency test, the child did not actually live with the claimant for more than half the year, or the age test, a 19-plus year old who is not a full-time student or disabled. Review the qualifying child rules before you claim.
Your filing status must reflect reality on December 31. Married workers who file as single to look eligible are filing a false status, and the return can be disallowed.
Both underreporting and overreporting income are common. Gig workers forget 1099 income; others guess at cash wages. The IRS matches your return against W-2s and 1099s, and mismatches trigger reviews. Report exact figures from your documents.
A typo in your child's SSN, a missing number, or an ITIN where an SSN is required will sink the claim. Double check every number before filing.
Two versions: earned income or AGI above the completed phase-out for your family size, or investment income above the $12,200 cap for 2026. Either one means zero credit, and claiming anyway invites a disallowance.
Unless you meet the narrow separated-spouse exception, married filing separately means no EITC. Some filers choose the status for other reasons and claim the credit out of habit. Do not.
Unemployment benefits, pensions, and Social Security are taxable income but not earned income for EITC purposes. You still need at least $1 of actual earned income.
Consequences escalate. At minimum, the EITC portion of your refund is delayed while the IRS reviews, which can take months. The IRS can deny all or part of the credit, and you must pay back any credit paid in error, plus interest. After a disallowance you generally must file Form 8862, Information to Claim Earned Income Credit After Disallowance, before claiming the EITC again.
If the error was due to reckless or intentional disregard of the rules, the IRS can ban you from claiming the EITC for the next two tax years. If the error was due to fraud, the ban is ten years. Honest mistakes do not trigger bans, but they still cost you the repayment, the interest, and the Form 8862 hassle. If you pay someone to prepare your return, you are still legally responsible for what is on it, so review the EITC lines yourself.
Respond promptly to any notice, such as a CP75 examination notice, and send exactly what is asked for: proof of residency for the child, relationship documents, income records. The fastest resolutions come from complete, on-time responses.
No. The 2-year and 10-year bans apply to reckless or intentional disregard of the rules and to fraud, not to honest errors. An honest mistake can still mean repaying the credit with interest and filing Form 8862 to claim the EITC again.
It is the IRS form, Information to Claim Earned Income Credit After Disallowance, that you file with your return to reclaim the EITC after the IRS has disallowed it in a prior year. You generally cannot skip it.
It varies, but EITC examinations routinely delay the credit portion of a refund by several months. Responding completely and quickly to IRS notices shortens the timeline.
Paid preparers have their own due diligence requirements for EITC claims and can face penalties for failing them. But you remain responsible for the accuracy of your own return, even when someone else prepares it.
