IRS Form 4506-T: How to Fill, Submit, and Understand Its Uses

A client’s mortgage is stalled because the lender needs income verification. Your self-employed client filed on time, but the underwriter won’t move without a tax transcript directly from the IRS. That’s exactly what IRS Form 4506-T is for—and knowing how to complete it without errors is the difference between a three-day turnaround and a three-week delay.

What Form 4506-T Actually Does

Form 4506-T, officially titled “Request for Transcript of Tax Return,” lets taxpayers authorize the IRS to release a transcript—not a copy of the original return—to themselves or a designated third party. Lenders, government agencies, and financial institutions use this transcript to verify that what a borrower reported on a loan application matches what the IRS has on file.

The IRS offers five distinct transcript types on this form:

• Return Transcript — summarizes line items from the original filed return
• Tax Account Transcript — shows adjustments made after the original filing, including payments and penalty assessments
• Record of Account Transcript — combines the return and account transcripts
• Wage and Income Transcript — pulls data from W-2s, 1099s, and other third-party information returns
• Verification of Non-Filing — confirms the IRS has no record of a return for the requested period

For most mortgage and loan verifications, lenders request the Return Transcript or Record of Account. If you’re helping a client prove they had no filing requirement for a given year, that’s when you check line 7 for the Verification of Non-Filing.

Who Needs This Form and When

Mortgage applicants: Underwriters almost universally require Form 4506-T as part of conventional and FHA loan processing. The lender submits the form directly to the IRS and compares the transcript against the borrower’s stated income.

Self-employed clients: A W-2 employee can verify income through pay stubs. A sole proprietor or S-corp owner can’t—the transcript is often the only clean, IRS-sourced document lenders will accept.

Taxpayers correcting records: If a client believes the IRS has an incorrect transcript on file, pulling one first is the diagnostic step before filing an amended return.

Government program eligibility: Certain federal and state benefit programs require transcript-based income verification rather than self-reported figures.

How to Fill Out Form 4506-T, Line by Line

Errors here cause rejection. Work through each section deliberately.

Lines 1a and 1b — Taxpayer Identity Enter the name exactly as it appears on the filed return. Line 1b takes the SSN, EIN, or ITIN. For a business return, use the EIN. For an individual return, use the SSN or ITIN. Mismatches between the name and identifying number are the single most common rejection cause.

Lines 2a and 2b — Spouse Information Complete these only when requesting a joint return transcript. Enter the spouse’s name and identifying number as filed. Leave blank for single or business returns.

Lines 3 and 4 — Addresses Line 3 is the current mailing address where the IRS will send the transcript. Line 4 is the previous address if it differs from the address on the most recently filed return. If your client moved after filing, this line matters—skip it and the IRS may reject the request because the addresses don’t reconcile.

Line 5 — Third-Party Recipient This is where you authorize a lender, institution, or firm to receive the transcript directly. Enter the third party’s name and contact information. If your client’s mortgage lender submits the form on their behalf, their information goes here. IRS

Line 6 — Transcript Type Check the box corresponding to the transcript type from the five options listed above. Only check one per submission unless the form’s instructions for your specific situation allow otherwise.

Line 7 — Verification of Non-Filing Check this box only when the client needs to confirm no return was filed for a specific year. Lenders occasionally require it when a gap year appears in the income history.

Line 9 — Tax Period Enter the end date of the tax year or period in mm/dd/yyyy format, as specified in the official form instructions. For a calendar-year individual return, that’s 12/31/YYYY. You can request up to four periods on a single form.

Signature and Date The form must be signed and dated before submission. An unsigned 4506-T is automatically rejected. For a joint return, both spouses must sign. For a business, an authorized officer signs.

Submission: Mail vs. Fax

The IRS accepts Form 4506-T by mail or fax. Which address or fax number you use depends on the state where the return was filed—the instructions on the back of the form include the correct routing by state. Fax is faster in practice. If a lender is submitting on behalf of a client, they typically have a dedicated IRS fax channel.

Processing time varies. Build in buffer time if you’re working against a loan closing date.

Common Mistakes That Delay Processing

• Name on line 1a doesn’t match IRS records exactly (middle initials, suffixes, business name abbreviations)
• Leaving line 4 blank when the client has moved since the last filing
• Requesting a period for which no return was filed without checking the Verification of Non-Filing box
• Submitting to the wrong IRS address for the client’s state
• Missing or undated signature

Frequently Asked Questions

What is the difference between Form 4506-T and Form 4506?

Form 4506 requests an actual copy of a filed tax return, which costs a fee per return. Form 4506-T requests a transcript—a summary of the return data—which is free. Lenders almost always want the transcript, not the full copy. Use 4506-T unless the requesting party specifically asks for an exact copy of the original return documents.

Can a lender submit Form 4506-T on behalf of a borrower?

Yes. The third-party recipient section on the form allows the taxpayer to authorize a lender or other institution to receive the transcript directly from the IRS. The borrower still signs the form. The lender then submits it and receives the transcript to compare against the loan application income figures.

Which transcript type should I request for a mortgage application?

Most mortgage underwriters want the Return Transcript or Record of Account Transcript. The Return Transcript shows the original filed data; the Record of Account combines that with any post-filing account activity. Check with the specific lender—some have a required transcript type written into their loan package instructions. About IRS Form 940

What happens if the IRS rejects Form 4506-T?

The IRS will return the form without processing it. Common rejection triggers include a name mismatch, missing signature, wrong address routing, or requesting a period with no filed return. Review the rejection notice carefully, correct the specific issue, and resubmit. This is why buffer time before a closing deadline matters.

How far back can I request transcripts using Form 4506-T?

The IRS generally retains transcript data for the current tax year plus the prior three years for most transcript types, though the Wage and Income Transcript may cover a longer window. The form allows up to four tax periods per submission. If you need records beyond the standard retention window, you may need to request an actual return copy using Form 4506 instead.
