Form 4506
Use a FORM 4506 template to make your document workflow more streamlined.
What Form 4506 does
Form 4506 is the IRS authorization used to request an exact copy of a previously filed federal tax return. The taxpayer identifies the return type, tax years, address, and delivery recipient, then signs the request so the IRS can evaluate disclosure. Unlike Form 4506-T, which requests a transcript, Form 4506 concerns copies of tax returns. A completed form may be prepared and electronically signed through signNow, but signNow does not approve the request or replace IRS processing. Retain the signed authorization with related tax records under applicable federal and state rules.

Form 4506 completion challenges
Taxpayers can enter an incorrect tax year, return type, or mailing address, causing the IRS to reject or delay the Form 4506 request. Missing signatures, dates, or taxpayer identification numbers can make Form 4506 incomplete and prevent the IRS from processing the authorization. Joint filers may overlook the second taxpayer signature, even though Form 4506 requires authorization from each taxpayer named on the requested return. Sensitive taxpayer information remains exposed when completed Form 4506 files are emailed broadly or stored without role-based access controls.

Form 4506 troubleshooting questions
These answers address Form 4506 completion, authorization, security, and signNow workflow questions without replacing IRS instructions or tax advice.
How do I correct an incorrect tax year on Form 4506?
Edit the tax-year fields in signNow before sending the document. Business plan users can use templates and audit trails to preserve the completed version. Confirm the requested years against the taxpayer’s records, because signNow facilitates completion but does not determine which returns the IRS can release.
Can I send Form 4506 without the taxpayer’s signature?
No. The taxpayer’s signature authorizes the IRS disclosure. signNow can route the form for electronic signature and capture intent, timestamps, and an audit trail. ESIGN and UETA support electronic signatures when their requirements are met, but they do not replace the taxpayer’s authorization or IRS processing rules.
What happens when a joint return has one signature missing?
A joint-return request may require authorization from both taxpayers named on the return. Use signNow’s signer routing to request each required signature before completion. The Business plan includes templates and audit trails, while the IRS—not signNow—decides whether the submitted authorization is sufficient.
