How to Fill Out IRS Form 4506-C (w/Examples) + FAQs

You fill out IRS Form 4506-C by entering your personal taxpayer details, the IVES participant information, the tax form numbers and years you want released, and then signing the consent box that authorizes the IRS to send your transcripts to a third party. The form is the official tool that lenders, mortgage underwriters, and other approved third parties use to pull your tax transcripts directly from the IRS so they can verify the income you claim on a loan or aid application.

The problem is simple but painful. One missing line, one wrong year, or one bad signature triggers an automatic rejection from the IRS, and a rejection can delay a mortgage closing, hold up an SBA 7(a) loan, or even cost you a locked interest rate. The IRS Income Verification Express Service program processes more than 15 million transcript requests every year through Form 4506-C, and industry data from the Mortgage Bankers Association shows roughly 1 in 5 are rejected on the first pass for clerical errors.

What Is IRS Form 4506-C and Why It Exists

IRS Form 4506-C is the IVES Request for Transcript of Tax Return. It is a one-page consent form that lets the IRS release your tax transcripts to an approved third party, called an IVES participant. The form replaced the old Form 4506-T for IVES users in 2021 and became the only acceptable version on March 1, 2023.

The form exists because of a federal privacy law. Internal Revenue Code Section 6103 makes your tax return data confidential. The IRS cannot share that data with a bank, an underwriter, or a government agency unless you sign a written consent. Form 4506-C is that written consent.

The role of the Taxpayer First Act

The Taxpayer First Act of 2019 forced the IRS to redesign the old 4506-T. Lawmakers worried that lenders and other third parties were storing transcript data and reusing it for purposes the taxpayer never agreed to. The new 4506-C requires you to name the exact third party who will receive your transcripts. It also requires the third party to certify that they will not redisclose the data without your permission.

The consequence of ignoring this rule is steep. A third party that redistributes your transcript without consent can face civil penalties of up to $1,000 per disclosure under IRC Section 7431. Willful unauthorized disclosure is a criminal misdemeanor under IRC Section 7213 with up to one year in prison. A common misconception is that lenders can pull your transcripts whenever they want during the life of a loan. They cannot. Each pull needs a fresh, signed 4506-C unless your original consent covers a defined period and purpose.

Who uses Form 4506-C

The main users are mortgage lenders, SBA loan officers, student loan refinance companies, immigration attorneys, and divorce litigators. Mortgage lenders are the heaviest users because Fannie Mae and Freddie Mac both require tax transcripts before they will buy a loan on the secondary market.

The form is also used in non-loan settings. Family law attorneys use it during divorce discovery to verify a spouse’s income. Immigration lawyers use it to support Form I-864 affidavits of support for visa sponsors. Even courts use 4506-C to verify income during bankruptcy filings under Chapter 13.

Line-by-Line Instructions for Form 4506-C

This section walks through every line of the October 2022 revision. Every entry must match what is already on file with the IRS. A mismatch on any field, even a missing apartment number, can trigger a rejection.

Line 1a: Taxpayer name shown on tax return

Enter the first name, middle initial, and last name exactly as they appear on the tax return for the year you are requesting. If you filed jointly and your name was listed first, you go on Line 1a. If you changed your name after filing, use the old name from the original return. The IRS matches by name on file at the time of filing, not your current name.

The consequence of using your current married name when you filed under your maiden name is automatic rejection by the IRS Return and Income Verification Services unit. A common mistake is to use a nickname like Mike when the return shows Michael. Always use the legal name from the return.

Line 1b: First Social Security Number on tax return

This is the SSN of the person on Line 1a. For a business return, this is the Employer Identification Number. The IRS matches by SSN/EIN, so double-check every digit. One transposed number causes an immediate reject.

If the taxpayer is deceased, the estate executor still uses the decedent’s SSN here and attaches a copy of Form 56 showing fiduciary authority. The consequence of skipping the Form 56 attachment is rejection because the IRS cannot verify who has the right to consent on behalf of a dead taxpayer.

Line 2a: Spouse name shown on tax return

If the return was filed jointly, enter the spouse’s name here exactly as it appears on the return. If the return was a single or head of household filing, leave Line 2a blank. Do not write N/A or none. The IRS scanner reads any text in this box as a data entry, and stray text causes rejections.

Line 2b: Second Social Security Number on tax return

This is the spouse’s SSN if you completed Line 2a. Like Line 1b, one wrong digit kills the request. Both spouses must sign the form on the signature line for joint returns.

Line 3: Current name, address, city, state, and ZIP

Enter your current mailing address. This is one of the few lines where you do not use the address from the original return. The IRS sends the transcripts to the IVES participant, not to you, so this address is mainly for identity matching and notice purposes.

A common mistake is to enter a P.O. box when the IRS has only a street address on file. The IRS does not require the address to match the return for Line 3, but the Compliance Services Collection Operations unit may flag mismatches for manual review, which adds days.

Line 4: Previous address shown on the last return

If you moved since filing the tax return, enter the address that appears on that return. If you have not moved, leave Line 4 blank. The IRS uses Line 4 as a secondary identity check, so accuracy matters.

The consequence of leaving Line 4 blank when you have moved is a higher chance of rejection. The IRS scanner cross-references Line 4 against the address shown on the actual return, and if they do not match, the request goes to manual review.

Line 5a: IVES participant name, address, and SOR mailbox ID

This block identifies the third party that will receive your transcripts. The IVES participant must be pre-approved by the IRS and assigned a Secure Object Repository (SOR) mailbox ID. You do not fill this in yourself unless you are the IVES participant. Your lender or processor fills this section before they send you the form to sign.

The consequence of an incorrect SOR mailbox ID is that the transcripts are routed to the wrong inbox or returned to the IRS undeliverable. The IVES participant has to start over with a new form and a new signature.

Line 5b: Customer file number

The customer file number is a 10-digit identifier the lender or third party uses to track your file in their system. It cannot be your SSN. The IRS prints this number on the transcript header so the lender can match the document back to your loan file.

A real-world example: Carlos, an SBA borrower, sees Loan #2026-00481 on the lender’s intake form. The processor enters that as the customer file number on Line 5b. When the transcript comes back, the SBA officer sees the same loan number on the header and files it with Carlos’s application.

Line 6: Transcript requested

Enter the tax form number you want a transcript for. The most common entries are 1040 for individual income tax, 1065 for partnerships, 1120 for corporations, and 1120-S for S corporations. Only one form number per 4506-C is allowed. If you need transcripts for both a 1040 and a 1065, you submit two separate forms.

The consequence of writing two form numbers on Line 6 is rejection. A common mistake is to write 1040 and W-2. W-2 wage data is requested separately on Line 7, not Line 6.

Line 6 checkboxes: 6a, 6b, 6c

These three boxes select the type of transcript on the Line 6 form. Box 6a is the Return Transcript, which shows most line items from your original return. Box 6b is the Account Transcript, which shows account activity, payments, and adjustments. Box 6c is the Record of Account, which combines 6a and 6b into one document.

Mortgage lenders almost always check Box 6a. SBA officers often check Box 6c because they want to see both the return data and any subsequent IRS adjustments. The consequence of checking the wrong box is that the lender gets a transcript that does not show what they need, and they have to ask you to sign a new 4506-C.

Line 7: Wage and Income transcript

Check Box 7 if you need a transcript of W-2, 1099, 1098, or 5498 data. This is separate from Line 6. You can check both Line 6 and Line 7 on the same form, and the IRS will return both transcripts in one package.

A common scenario: Priya, a self-employed software contractor, applies for a conventional mortgage. Her lender checks both Line 6a (her 1040 transcript) and Line 7 (her 1099 wage and income transcript) so they can confirm the 1099-NEC totals match the Schedule C she reported.

Line 8: Verification of Non-filing

Check Box 8 only if you did not file a tax return for the year requested and need IRS confirmation of that fact. This is common for FAFSA student aid applications and certain Medicaid filings.

The consequence of checking Box 8 when you actually filed a return is that the IRS returns a no record response, which the lender reads as either fraud or error. Always confirm whether you filed before checking this box.

Line 9: Year or period requested

Enter the tax year ending date in MM/DD/YYYY format. For most individual filers, this is 12/31/2025 for the 2025 tax year. You can request up to four years on one form. Each year must be listed separately.

A real-world example: Jamal, a mortgage borrower applying in March 2026, lists 12/31/2025, 12/31/2024, and 12/31/2023 on Line 9. His lender wants three years of returns to qualify him under Fannie Mae self-employed borrower guidelines.

Signature block and attestation

The signature block has a mandatory attestation checkbox above the signature line. By checking this box, you certify under penalty of perjury that you have the authority to sign and that you understand the IRS will release the requested transcripts to the IVES participant named on Line 5a. The form must be signed within 120 days of the IRS receiving it.

For joint returns, both spouses must sign and date. For business returns, an officer with binding authority must sign and include their title. The consequence of a missing title for a business signer is rejection. The consequence of an expired signature (older than 120 days) is also rejection, even if every other field is perfect.

Three Real-World Scenarios

The table below shows how borrowers navigate common 4506-C situations and the consequence of each choice.

Borrower Action IRS or Lender Outcome
Maria signs a 4506-C for a 2024 1040 transcript with all fields matching her return IRS releases the transcript to the IVES mailbox within 3 business days
Brian forgets to check Box 6a, 6b, or 6c on Line 6 IRS rejects the form and returns a no box checked error
Linh signs the form on January 5, 2026, but her lender does not submit it until May 10, 2026 IRS rejects because the signature is more than 120 days old

Named Examples Across Use Cases

These three named examples show the form in action across the most common scenarios.

Example 1: Maria, a W-2 mortgage borrower

Maria works as a registered nurse in Phoenix and applies for a conventional 30-year mortgage. Her lender, an IVES-approved bank, sends her a pre-filled 4506-C with the lender’s name, address, and SOR mailbox ID on Line 5a. Maria fills in Lines 1a, 1b, and 3 with her personal data, lists 1040 on Line 6, checks Box 6a, and writes 12/31/2024 and 12/31/2023 on Line 9.

Maria signs the form on March 14, 2026. Her lender uploads it to the IVES portal the same day. The IRS releases her transcripts on March 17, 2026. The lender sees her adjusted gross income matches the W-2 figures she gave on her loan application, and underwriting moves forward.

Example 2: Carlos, an SBA 7(a) loan applicant

Carlos owns a small bakery in Miami and applies for a $250,000 SBA 7(a) loan. The SBA SOP 50 10 requires three years of business and personal tax transcripts. Carlos signs two separate 4506-C forms. One requests his personal 1040 transcripts on Line 6 (Box 6a). The other requests his bakery’s 1120-S corporate transcripts.

Carlos enters his EIN on Line 1b for the business form and signs as President in the title block. He also checks Box 6c to get the Record of Account, because his SBA officer wants to see if the IRS made any adjustments to his 2024 return. The transcripts return within five business days, and his loan moves to final review.

Example 3: Linh, an H-1B visa sponsor

Linh sponsors her parents for green cards and must file Form I-864 with USCIS. The instructions allow her to attach IRS tax transcripts instead of full returns. Linh fills out a 4506-C, lists 1040 on Line 6, checks Box 6a, and lists three years on Line 9.

Linh’s IVES participant is the immigration law firm handling her case, which holds a valid IVES agreement with the IRS. She signs the form, the firm submits it, and the transcripts arrive in the firm’s SOR mailbox three days later. The firm forwards them to USCIS as part of the I-864 packet.

Mistakes to Avoid

These are the most common errors that get a 4506-C rejected. Each one carries a specific negative consequence.

  • Mismatched name between Line 1a and the original return causes an automatic IRS reject and a delayed loan closing.
  • Wrong SSN on Line 1b sends the IRS searching for a record that does not exist, which returns a no record found error.
  • Skipping Line 4 after a recent move triggers manual review and adds three to seven days of processing time.
  • Checking more than one box on Line 6 (6a, 6b, and 6c together is fine; combining with multiple form numbers is not) causes a form number conflict rejection.
  • Listing two different tax form numbers on Line 6 forces the IRS to reject the entire request.
  • Submitting a form signed more than 120 days ago triggers an automatic expired signature rejection.
  • Forgetting to include the signer’s title on a business return rejects the form for missing authority.
  • Using a P.O. box on Line 3 when the IRS has a street address sometimes routes the form to manual review and adds days.
  • Skipping the attestation checkbox above the signature line voids the consent and causes immediate rejection.
  • Writing N/A or none on Line 2a or 2b for single filers causes a scanner read error.

Do’s and Don’ts

These ten rules separate a clean submission from a costly rejection.

Do’s:

  • Do match every name, SSN, and address to the IRS’s records, because the IRS scanner is unforgiving on data mismatches.
  • Do check the correct transcript box on Line 6, because the wrong box returns the wrong document and forces a re-sign.
  • Do confirm the IVES participant’s SOR mailbox ID before signing, because the wrong ID delivers your data to the wrong inbox.
  • Do sign within 120 days of submission, because the IRS rejects any form older than 120 days.
  • Do keep a copy of the signed form for your records, because the Fair Credit Reporting Act gives you a right to know what data third parties collect about you.

Don’ts:

  • Do not sign a blank 4506-C for a lender, because that gives the lender unlimited consent and exposes you to identity risk.
  • Do not list more than one tax form number on Line 6, because the IRS rejects multi-form requests.
  • Do not check Box 8 if you actually filed a return, because the IRS will return a no record response that looks like fraud.
  • Do not use a current married name when the original return showed your maiden name, because the IRS matches against the name on file at filing.
  • Do not submit the form yourself if your lender is the IVES participant, because the IRS only accepts 4506-C requests through the IVES portal from registered participants.

Pros and Cons of Using Form 4506-C

The form has clear benefits and real drawbacks. Knowing both helps you decide when to push back on a lender’s request.

Pros:

  • Direct IRS verification eliminates fraud risk for lenders, which often leads to better loan pricing for borrowers with clean returns.
  • Transcripts return in three to five business days through the IVES portal, which is faster than mailing in a Form 4506.
  • The taxpayer keeps control because each request requires a fresh signature, which protects against open-ended data sharing.
  • The transcript is free to the borrower, because the IVES participant pays the $4.00 per transcript fee directly to the IRS.
  • The form is standardized, so every lender uses the same fields, which reduces confusion across loan applications.

Cons:

  • One typo causes a full rejection, which can delay closing by a week or more.
  • The 120-day signature rule forces re-signing if your loan process drags on past four months.
  • Joint filers must coordinate two signatures, which is hard during divorce or separation.
  • The IRS sometimes takes longer than five days during peak filing season (February through April), which slows tax-season homebuying.
  • The form gives the IVES participant access to all line items on the transcript, which is more data than some borrowers want to share.

Form 4506-C vs Form 4506 vs Form 4506-T

These three forms look alike but serve different purposes. The table below shows how they differ.

Feature Detail
Form 4506 Full copy of the actual return, takes 75 days, costs $30 per return
Form 4506-T Free transcript request, sent to the taxpayer or a third party, no longer used by IVES participants
Form 4506-C IVES-only transcript request, used by approved third parties, returns transcripts in 3 to 5 days

Key Entities You Should Know

Several IRS units, federal laws, and outside agencies touch every 4506-C. Knowing each role helps you understand who is doing what to your data.

Court Rulings and Precedent

Several court cases shape how lenders and third parties handle 4506-C data. In Aloe Vera of America, Inc. v. United States, the Ninth Circuit held that unauthorized disclosure of tax return data by federal employees triggers Section 7431 damages. Courts apply the same logic to private IVES participants who redisclose transcripts.

In Stokwitz v. United States, the Ninth Circuit ruled that documents not in IRS files do not get Section 6103 protection, which means once a transcript is in your lender’s hands and you give them a separate consent to share it, GLBA and state privacy laws govern, not Section 6103. The practical consequence is that you should read every consent form your lender hands you, not just the 4506-C.

Federal vs State Considerations

Federal law controls the 4506-C because it is an IRS form. The Internal Revenue Code and the Taxpayer First Act set the baseline rules for consent and disclosure. No state can override Section 6103.

State law still matters for the downstream handling of transcripts. California’s California Consumer Privacy Act gives borrowers the right to know what personal information a lender stores. New York’s SHIELD Act requires lenders to notify borrowers if transcript data is breached. Texas, Florida, and Illinois have their own data breach notification laws that cover transcript data once it is on the lender’s servers.

FAQs

Is IRS Form 4506-C the same as Form 4506-T?

No. Form 4506-C is the IVES-only version that replaced 4506-T for third-party transcript requests on March 1, 2023. Individual taxpayers ordering their own transcripts still use 4506-T or the Get Transcript online tool.

Do I have to pay to file Form 4506-C?

No. The IVES participant pays the $4.00 per transcript fee directly to the IRS. The borrower never sees a charge for a 4506-C transcript request, though some lenders pass the fee through in closing costs.

Can I refuse to sign a 4506-C my lender sends me?

Yes. You can refuse, but the lender will almost certainly deny your loan because Fannie Mae, Freddie Mac, and SBA all require transcript verification. Refusing the form usually means walking away from the loan.

Does the form expire after I sign it?

Yes. The IRS rejects any 4506-C received more than 120 days after the signature date. If your loan drags on past four months, your lender will ask you to sign a fresh form.

Can both spouses use one 4506-C for a joint return?

Yes. A joint return uses one 4506-C, but both spouses must sign and date the form. A missing second signature causes automatic rejection.

Will the IRS send the transcript to me or to my lender?

No, the transcript does not go to you. The IRS sends it directly to the IVES participant’s Secure Object Repository mailbox listed on Line 5a. You can request a separate copy using Form 4506-T or the Get Transcript tool.

Can I use Form 4506-C for state tax returns?

No. The 4506-C only works for federal IRS records. State transcripts require separate forms from each state’s department of revenue, like the California Franchise Tax Board.

Does signing a 4506-C give my lender ongoing access to my returns?

No. Each 4506-C authorizes a single transcript pull for the years and forms listed. The lender must get a new signed form for any future request.

Is a digitally signed 4506-C accepted?

Yes. The IRS accepts electronic signatures from IVES participants who use approved e-signature platforms and follow the IRS digital signature standards published in 2021.

Can I get a transcript for a year I did not file a return?

Yes. Check Box 8 on the form to request Verification of Non-filing. The IRS will send a letter confirming there is no return on file, which is often required for FAFSA and Medicaid applications.

What happens if my 4506-C is rejected?

No loan moves forward until you fix it. The IRS sends a rejection code to the IVES participant explaining the error. You sign a corrected form, the participant resubmits, and the clock starts over.

Does Form 4506-C work for deceased taxpayers?

Yes, but the executor must sign and attach Form 56 showing fiduciary authority. Without Form 56, the IRS cannot verify who has the right to consent on behalf of the decedent.
