IRS authorization used by an approved requester to obtain tax transcripts for mortgage income verification.
Form 4506-C, IVES Request for Transcript of Tax Return, authorizes an approved requester to obtain specified tax transcripts through the IRS income-verification service.
Form 4506-C matters because a lender may need IRS tax-record information to verify the Tax Return or other tax-based income documentation in a mortgage file. The form records the taxpayer’s consent and identifies the requester, transcript type, tax form, and periods covered.
The form is not blanket permission for the lender to obtain every IRS record. It should specify the records being requested and the party authorized to receive them. An incomplete, inaccurate, altered, or stale form may fail processing and delay underwriting.
Borrowers should review the completed information before signing. The taxpayer name and identifying number, current or previous address as required, IVES participant, client or lender, tax form number, transcript type, and requested years or periods should match the intended request.
Borrowers may sign Form 4506-C during application, processing, underwriting, or closing, depending on lender workflow. The lender or its authorized transcript provider submits the form through the IRS Income Verification Express Service, commonly called IVES.
The transcript is then returned through the authorized process rather than handed to the borrower as part of the form. The lender compares the IRS record with documents in the mortgage file and resolves discrepancies when necessary.
| Form detail | Why it matters |
|---|---|
| Taxpayer name and identification information | Connects the request to the correct taxpayer record |
| Current and prior address fields | Helps the IRS match the requested account |
| IVES participant and client information | Identifies who requests and receives the transcript |
| Tax form number | Specifies the return or information record involved |
| Transcript type | Determines the kind of IRS record requested |
| Tax years or periods | Limits the request to stated filing periods |
| Signature, date, and authority | Documents valid taxpayer consent |
For a jointly filed return, signature requirements can depend on the record and request. A person signing for a business must have authority to do so. Borrowers should ask the requesting lender or tax professional about an unclear field rather than signing an unfinished form.
A self-employed borrower provides personal tax returns for 2024 and 2025. The lender prepares Form 4506-C requesting tax return transcripts for those same years and identifies its approved IVES participant and client information.
The borrower checks that the names, tax-form number, years, and recipient details are complete before signing. The lender receives the requested transcripts and compares them with the returns used in the income analysis. Form 4506-C authorized the request; it did not calculate the borrower’s income.
A transcript request can fail when names or taxpayer numbers do not match IRS records, an address field is wrong, the tax year or form number is missing, the signature is not acceptable, or the requested record is not yet available. A corrected Form 4506-C may be needed.
The issue should be resolved rather than bypassed with an unrelated document. A borrower-provided transcript or return copy may be useful, but it does not necessarily replace the lender’s required third-party verification process.
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 differs from Form 4506-T, which a taxpayer uses to request a transcript for the taxpayer’s own purposes rather than authorizing an IVES participant to receive records through Form 4506-C. It also differs from Form 4506, which requests a copy of a tax return rather than a transcript.
It also differs from Verification of Income because income verification is the broader process; Form 4506-C is one possible authorization used within it.
