The Earned Income Tax Credit (EITC) requires taxpayers to document identity, earned income, filing status, and any qualifying children. The main authoritative guidance is IRS Publication 596 authored by the Internal Revenue Service, which lists the types of evidence the agency accepts and explains recordkeeping expectations. The Social Security Administration provides verification for Social Security numbers used to claim the credit.
Proof of income and work
To establish earned income you will typically use W-2 forms, Form 1099 for contract work, or business records showing receipts and expenses for self-employment. Pay stubs, employer statements, and bank deposit records can support amounts reported when official forms are delayed. The Internal Revenue Service advises keeping these documents with your tax records to substantiate claimed wages or self-employment income.
Proof of qualifying child and residency
If claiming a qualifying child, evidence of relationship and residency is central. Documents such as birth certificates, adoption papers, court orders establishing custody, school or medical records that show the child lived with you, and official letters with addresses are commonly accepted. Proof of residency can include lease agreements, utility bills, school attendance records, or day-care receipts. For children in nontraditional living arrangements, the Internal Revenue Service guidance explains which records and statements can demonstrate the child lived with you for more than half the year.
Proof of identity and Social Security numbers must come from the Social Security Administration or be reflected on official documents such as Social Security cards or valid Social Security number notices. ITIN holders should follow IRS procedures for identification and eligibility verification.
Evidence, consequences, and special circumstances
Maintaining clear documentation matters because insufficient proof can delay refunds, lead to denial of the credit, or result in repayment and penalties if an audit finds the claim unsupported. The Internal Revenue Service pursues erroneous claims through audits and adjustments. People in seasonal, migratory, military, or tribal communities may face extra challenges obtaining conventional documents; in those cases school records, tribal enrollment documents, military orders, or consistent third-party affidavits can be critical to substantiate residency and relationship. Keeping organized records and consulting the guidance in IRS Publication 596 authored by the Internal Revenue Service and verification tools from the Social Security Administration reduces risk and improves the chance of a smooth claim.
