What Form 4506-C is and how it works
Form 4506-C is an IRS authorization that lets a taxpayer consent to the disclosure of tax return information to a named recipient. The taxpayer identifies personal details, the tax forms and years requested, the recipient, and the authorization purpose, then signs and dates the form. A lender or other authorized recipient uses the completed consent to request transcripts from the IRS. signNow can upload the form, detect fillable fields, route it for electronic signature, and preserve the completed authorization with an audit trail.
Who uses Form 4506-C
Mortgage lending
Mortgage lenders and loan processors use Form 4506-C to obtain a taxpayer’s consent for IRS transcript disclosure during income verification. They can route the authorization to borrowers, confirm required fields, and retain the signed record with the loan file.
Financial services
Financial institutions and tax-information recipients use Form 4506-C when the taxpayer authorizes disclosure to a specifically identified recipient. Controlled templates, signer authentication, and audit trails help teams distinguish an executed authorization from an uncompleted request.

Privacy and disclosure pitfalls
Taxpayer names, addresses, or tax identification details may be exposed when a completed Form 4506-C is emailed broadly or stored without role-based access controls. A recipient may send Form 4506-C before confirming that the taxpayer authorized the specific recipient and purpose stated on the IRS authorization. A signature without a preserved timestamp, signer identity record, or completion certificate can make later proof of taxpayer consent more difficult. Reusing an old template can carry incorrect tax years, recipient details, or authorization language into a new Form 4506-C request.
Retention and record-keeping practices
Keep the signed authorization, evidence of consent, and related delivery records together while applying the retention rule that fits the underlying tax or lending file.
Apply the correct IRS retention period
Export evidence after signing
Limit access to taxpayer information

Troubleshooting Form 4506-C workflows
Resolve field, authorization, electronic-signature, retention, and IRS-processing questions before relying on a completed 4506-C authorization.
Upload the original Form 4506-C PDF again, then review each detected field against the printed form. signNow’s field detection can place fields, but the sender remains responsible for verifying taxpayer names, addresses, tax years, and signature locations.
The Business plan includes legally binding eSignatures, templates, audit trails, and mobile apps. If your workflow requires bulk send, Business Premium adds that capability; Enterprise adds advanced signer authentication and conditional or formula fields.
Form 4506-C authorizes the IRS to disclose tax return information to a named recipient. Before sending, verify the taxpayer’s identifying details, the recipient’s name and address, tax years, and the stated purpose because signNow cannot correct an inaccurate authorization.
ESIGN and UETA generally recognize electronic signatures when intent, consent, attribution, and record retention are established. For consumer-facing delivery, 15 U.S.C. §7001(c) also requires electronic-record disclosures and access procedures.
The audit trail records signing actions, timestamps, and related document history. Export the completed Form 4506-C and certificate of completion after signing, then retain them under the organization’s IRS and lending-record policy.
Form 4506-C is an IRS authorization, not a substitute for the tax return itself. A completed authorization does not guarantee IRS transcript delivery; the recipient must follow IRS processing requirements and investigate rejected or incomplete requests separately.
