IRS transcript request authorization often used to support mortgage income verification.
Form 4506-C is an IRS transcript request authorization that allows a lender or authorized party to request or verify tax transcript information for a mortgage file.
Form 4506-C matters because tax-record verification can be part of mortgage underwriting. The form helps the lender confirm that income documentation, tax returns, and tax-record information are consistent.
It also matters because borrowers sometimes treat the form as a minor closing document. In reality, an incorrect or incomplete 4506-C can delay transcript verification and create underwriting conditions.
Borrowers may sign Form 4506-C during application, processing, underwriting, or closing depending on lender workflow. It is commonly tied to income review when tax returns or transcripts are needed.
The term becomes practical when the lender needs to verify Tax Return information, order a Tax Transcript, or clear an income condition.
A borrower provides two years of tax returns for self-employed income. The lender asks the borrower to sign Form 4506-C so tax transcripts can be requested and matched against the income documentation in the file.
Form 4506-C differs from a Tax Transcript because the form authorizes transcript access, while the transcript is the tax-record information.
It differs from a Tax Return because the return is the filed tax document, while Form 4506-C is a request or verification authorization.
It also differs from Verification of Income because verification of income is the broader process; 4506-C is one possible tool in that process.
