Tax Information Form 4506-C
What the Tax Information Form 4506-C Is and when it’s used
Why the 4506-C matters for income verification
The 4506-C establishes taxpayer authorization for third-party transcript delivery, streamlines verification through IVES, and reduces reliance on paper returns. Proper use limits processing delays and helps ensure lenders and verifiers receive IRS-certified tax data for underwriting, loan closings, or benefits determination.
Primary users and typical requestors
Common users need clarity on roles before requesting transcripts.
- Mortgage lenders and brokers who require IRS-certified income verification for loan underwriting and closing.
- Banks, credit unions, and loan servicers performing credit decisions or title-related verifications.
- Income verification companies and authorized third-party processors enrolled as IVES participants.
Understanding who signs and receives transcripts reduces routing errors and liability.

Risks and potential consequences of errors
Common preparation and submission mistakes to avoid
- Failing to match the taxpayer name and Social Security number exactly, which causes frequent IRS rejections and adds days to processing.
- Not confirming IVES enrollment for the requesting party before transmission, leading to rejected electronic deliveries and manual workarounds.
- Forgetting to include precise tax years or transcript types, producing either incomplete records or unnecessary, broader data returns.
- Using insufficient signer authentication or failing to capture explicit consent, which increases legal and verification risk for third-party recipients.

Frequently asked questions and troubleshooting
-
How long does processing take?
Processing times vary by submission channel and IRS workload. Electronic IVES deliveries are typically faster than mailed requests; allow additional time for notarization or identity verification steps that may be required.
-
Who must sign the 4506-C?
The taxpayer or an authorized representative must sign and date the form. When an authorized agent signs, documentation proving the agent’s authority should be retained to support the IRS disclosure request.
-
Can the form be signed electronically?
Yes — electronic signatures meet ESIGN and UETA requirements when intent and consent are captured and the platform retains an audit trail capable of reproduction for legal purposes.
-
What causes common IRS rejections?
Frequent causes include mismatched names or SSNs, unsigned forms, incorrect tax year entries, and requestors not enrolled as IVES participants. Verify each field before submission to reduce rework.
-
How do I revoke a consent?
To revoke consent, obtain a signed revocation from the taxpayer and notify the recipient and IRS per your contractual and operational procedures; document the revocation for audit purposes.
-
Where should completed forms be stored?
Store completed 4506-C forms in encrypted, access-controlled systems with audit logs. Retain records consistent with IRS and industry-specific retention rules to meet potential audit or compliance requests.
