Form 8862 is your second chance to claim valuable tax credits after the IRS has previously denied or reduced them. Think of it as a "reinstatement application" that lets you prove you now qualify for credits that were taken away before. The form covers four major tax credits: the Earned Income Credit (EIC), Child Tax Credit (CTC) and related child credits (RCTC/ACTC), Credit for Other Dependents (ODC), and the American Opportunity Tax Credit (AOTC) for education expenses.

When the IRS denies one of these credits, it's not necessarily permanent. If your circumstances have changed or you can now provide proper documentation, Form 8862 gives you the opportunity to reclaim these benefits. However, this form isn't needed for simple math errors—those are automatically corrected. You only need Form 8862 when the IRS questioned whether you actually qualified for the credit in the first place, such as disputes over whether a child lived with you or whether you met income requirements.

What Form 8862 Is For

Form 8862 is your second chance to claim valuable tax credits after a prior IRS denial or reduction for reasons other than math or clerical errors. It applies to EIC, CTC/RCTC/ACTC, ODC, and AOTC. If your circumstances changed or you can now document eligibility, this form lets you reclaim those benefits. IRS.gov

When You’d Use Form 8862 (Late/Amended)

You must file Form 8862 attached to your current year's tax return—not as a standalone document—when both of these conditions apply: (1) the IRS previously reduced or disallowed your claim for the EIC, CTC/ACTC/ODC, or AOTC for any reason other than a math or clerical error, and (2) you now want to claim that same credit and believe you meet all the requirements. The form essentially tells the IRS, "I know you denied this credit before, but here's why I qualify now."

Important Exceptions

• If you already filed Form 8862 once after a denial and the IRS approved your credit, you don't need to file it again unless your credit gets denied a second time.
• If you're claiming the EIC without a qualifying child and the only issue was that a specific child didn't qualify (but you otherwise met the rules), you can skip Form 8862.

Ban Periods

You cannot claim these credits—even with Form 8862—for 2 years after a determination of "reckless or intentional disregard" of the rules, or for 10 years after a fraud determination. IRS.gov

Key Rules or Details for 2021

The 2021 tax year brought several important adjustments, especially for the Earned Income Credit.

EIC Age and Residency Changes

• Without a qualifying child: Minimum age dropped from 25 to 19 (or 18 for qualified former foster youth or qualified homeless youth); no maximum age limit.
• Specified students: Minimum age remained 24.
• Separated spouses: You could claim the EIC if you lived with your qualifying child for more than half the year and either didn’t live with your spouse for the last 6 months of 2021 or were legally separated.

SSN Rules for Children (EIC)

• If a child didn’t have a valid SSN by the return due date, you could still use the "with qualifying child" rules to determine eligibility, but you had to calculate the amount using the "without qualifying child" rules.

Child Tax Credit (CTC/RCTC/ACTC) and ODC

• The Child Tax Credit expanded in 2021 and was fully refundable for qualifying children under age 18 (meeting residency requirements).
• Children needed a valid SSN for CTC/RCTC/ACTC; ODC accepted SSN/ITIN/ATIN.

Critical Identification Requirement

• You and your qualifying children must have the required TINs issued on or before the return due date (including extensions). No TIN, no credit—even on amended returns. IRS.gov

Step-by-Step (High Level)

Part I: Determine Eligibility and Which Credits You’re Claiming

Step 1: Determine if You Need the Form

Check whether your credit was actually denied (you should have received IRS correspondence), verify the denial wasn't just a math error, and confirm you're not in a ban period (2-year or 10-year prohibition).

Step 2: Complete Part I

Enter the tax year you're claiming (2021) and check the boxes for which credits you're now claiming—EIC, CTC/RCTC/ACTC/ODC, or AOTC. Multiple credits can be claimed on one form.

Part II: Earned Income Credit (EIC)

Step 3: Answer General EIC Eligibility

Indicate whether you could be claimed as someone else's qualifying child—if yes, you cannot claim EIC. Then complete either:

• Section A (With Qualifying Children): Provide proof each child lived with you more than half the year in the U.S.
• Section B (Without Qualifying Child): Verify you (and your spouse, if MFJ) lived in the U.S. for more than half the year and met the age rules.

Part III: Child Tax Credits (CTC/RCTC/ACTC/ODC)

Step 4: List Dependents and Tests

List each child or other dependent, confirm they lived with you more than half the year, verify dependency, and confirm U.S. citizenship/residency status.

Part IV: American Opportunity Tax Credit (AOTC)

Step 5: Student Eligibility

List each student and confirm they met the eligible student requirements (half-time enrollment, pursuing a degree, not completed first four years, no AOTC in four prior years, no felony drug convictions).

Part V: Tiebreaker Situations

Step 6: If Another Person Could Claim the Child

Complete Part V only if your qualifying child could also be claimed by someone else. This helps the IRS apply tiebreaker rules.

Filing

Step 7: Attach the Form to Your Return

Attach Form 8862 to your complete tax return with all required schedules (e.g., Schedule EIC, Schedule 8812, Form 8863). Submit everything together—Form 8862 isn’t valid by itself. IRS.gov

Common Mistakes and How to Avoid Them

1) Filing Form 8862 When You Don’t Need It

If the IRS already approved your credit after you filed Form 8862 once, don’t file it again unless the credit was denied again.

2) Claiming Credits During a Ban Period

A 2-year or 10-year ban trumps Form 8862. Filing during the ban results in automatic denial. Check IRS correspondence for ban language.

3) Missing the Residency Requirement

For EIC, you (or your child) must have lived in the U.S. for more than half the year (183 days; 184 in leap years). Territories like Puerto Rico don’t count for this test. Active-duty military abroad may have exceptions.

4) Not Providing Complete Documentation

Expect requests for school/medical records, landlord statements, or other proof. Be ready to substantiate residency and eligibility.

5) Filing the Form Alone

Form 8862 must be attached to a current return with supporting schedules. It is not an appeal or standalone submission.

6) Ignoring the “Other Person” Rule

If another person could claim the child, complete Part V so tiebreaker rules can be applied. IRS.gov

What Happens After You File

Once you submit Form 8862 with your tax return, the IRS will review your claim more carefully than a typical return. Processing may take longer—refunds for returns claiming EIC/ACTC are held until mid-February, and Form 8862 adds extra scrutiny.

• The IRS may request additional documentation (e.g., school or medical records, landlord statements) to verify eligibility. Respond promptly and completely.
• Outcomes:
  • Approval: Credits allowed; you generally won’t need Form 8862 again unless a future denial occurs.
  • Partial approval: Some credits allowed, others denied.
  • Denial: You’ll receive an explanation and can appeal (IRS Office of Appeals or Tax Court), or amend with better proof.

Recordkeeping: Save Form 8862, supporting documents, and IRS correspondence for at least three years after filing. IRS.gov

FAQs

Q1: Do I need to file Form 8862 every year after my credit was denied?

No. File it the first year you reclaim a denied credit. If the IRS approves it, you don’t file again unless there’s another denial.

Q2: Can I file Form 8862 by itself or does it need to be attached to my tax return?

Form 8862 must be attached to your Form 1040/1040-SR; it’s not a standalone or appeal form.

Q3: What’s the difference between a “math error” denial and other denials?

Math errors are simple corrections and don’t require Form 8862. Denials questioning eligibility (child qualification, income limits, residency) do require it to reclaim.

Q4: If I’m claiming EIC without a qualifying child and my prior denial was that my child didn’t qualify, do I still need Form 8862?

No. If you otherwise met EIC rules, you can claim EIC without a qualifying child without filing Form 8862.

Q5: My spouse and I filed jointly when our credit was denied. Can one of us file Form 8862 separately now?

Yes, if you’re not filing jointly now. Each spouse’s eligibility is assessed separately. If still MFJ, both participate.

Q6: How long does it take to get my refund after filing Form 8862?

Expect delays. EIC/ACTC refunds are held until mid-February, and Form 8862 reviews can add weeks to months.

Q7: What happens if I’m in a ban period but file Form 8862 anyway?

The IRS will automatically deny your credit. Ban periods (2 years for reckless disregard, 10 years for fraud) cannot be overridden by filing. IRS.gov
