Form 4506-C is the IRS form a borrower signs to let a lender, or the verification service it uses, request tax transcripts directly from the IRS through its Income Verification Express Service. The lender compares those transcripts with the returns the borrower supplied, to confirm the figures it underwrote are the figures that were filed. SBA lenders must complete that verification before the loan disburses. Delays usually come from mismatches: amended or unfiled returns, a name, address or form type that does not match IRS records, or a return filed too recently to appear.
- What it is
- The IRS request for tax transcripts sent through its verification service
- Who signs
- Each taxpayer whose returns are verified: the business, and often the owners
- What comes back
- Transcripts of what the IRS has on file, not copies of the returns
- When it matters
- Before disbursement; SBA lenders cannot fund until it verifies
- Most common problem
- Transcripts that differ from the returns in the file
How the form works
The 4506-C is a request and an authorization in one. The taxpayer, a business or an individual, fills in its name, taxpayer identification number and address exactly as the IRS has them, names the type of return and the tax years requested, and signs. The form names the verification participant who will receive the transcripts: the lender itself or, more often, a vendor the lender uses. That participant submits it to the IRS through the Income Verification Express Service and receives the transcripts electronically.
The IRS does not accept a form that has sat around: it must be received within 120 days of the signature date. A lender will therefore often ask for the form at application and again near closing, or ask for a fresh signature if the first one has aged out. The form covers only the years and return types written on it, so a business with a parent company and a subsidiary, or an owner with several entities, may sign several.
The lender verifies what the IRS received. A return prepared but never filed, or filed after the lender's pull, does not exist as far as the transcript is concerned.
Why lenders verify returns directly
A lender sizes the loan from the numbers in the file: revenue, earnings, the owners' income, the debt service coverage. Those numbers are only as good as the documents behind them. A transcript is the IRS's own record, delivered to the lender without passing through the borrower's hands, so it answers the one question a PDF of a return cannot: was this what was filed?
SBA makes the check mandatory. Under SOP 50 10, the lender must verify the financial information it relied on against IRS transcripts before the loan disburses, and resolve any significant difference. A lender that funds without doing so risks the guaranty. On an acquisition, the target business's returns are what the loan was sized on, so lenders commonly need a 4506-C signed for the selling entity as well, which means the seller has to cooperate. Conventional lenders are not bound by SBA's rule but many use the same form for the same reason.
What the IRS sends back
The request names a transcript type. Each one answers a different question, and knowing which one the lender pulled explains most apparent mismatches.
| Transcript | What it shows | What it will not show |
|---|---|---|
| Return transcript | Most line items of the original return as filed | Later amendments or IRS adjustments |
| Account transcript | Filing date, payments, penalties and adjustments, including amendments | The detailed line items of the return |
| Record of account | The return transcript and account transcript together | Anything not yet processed |
| Verification of non-filing | That the IRS has no return on record for the year | Whether a return is in transit |
| Wage and income transcript | Income reported by third parties on W-2 and 1099 forms | Business income and deductions |
The return transcript is the usual starting point. Where a return was amended, only the account transcript or record of account shows it, and the lender will need to see that the amended figures are the ones it underwrote.
What causes mismatches and delays
A mismatch rarely means anyone lied. It usually means the transcript and the return in the file are describing different things. These are the causes an underwriter sees most often:
| Cause | What the lender sees | How it is resolved |
|---|---|---|
| Amended return | Return transcript shows the original figures | Pull the account transcript; supply the amended return and the reason |
| Return in the file was never filed, or filed late | No record, or figures that differ from a draft | File it, or supply the filed version; the lender re-pulls |
| Recently filed return | No record for the latest year yet | Filing extension and proof of filing; a later re-pull |
| Name, TIN or address mismatch | Request rejected | Match the IRS's records exactly, including the address on the last return filed |
| Wrong form type | No record under that form | Request the form actually filed, for example 1120-S rather than 1065 |
| Single-member LLC | No business return exists | The income is on the owner's 1040; request that transcript |
| Group filing one consolidated return | No separate return for the subsidiary | Request the parent's return; the lender reads the group together |
Separately from the transcript check, returns often differ from the company's own financial statements because tax and book accounting treat some items differently. That is normal and is reconciled in underwriting; the transcript check is about whether the return itself is genuine. See when the seller's financials do not match the tax returns.
How to avoid a closing delay
Most transcript problems can be found and fixed before the form is signed, not after a failed pull. Four habits prevent most of them:
- Send filed returns, not drafts. The returns in the file should be the ones the IRS received, with every amendment attached and explained.
- Say which years are not yet filed. If the most recent year is on extension, include the extension. Transparent's SBA checklist asks for it for this reason.
- Copy names and addresses from the last return. The entity's legal name, EIN and address should match what the IRS has, even if the business has since moved.
- Map the entities. List which company files which return, which LLCs are disregarded and which companies file together, so the lender requests the right thing for each.
On an acquisition, raise the seller's 4506-C early in the process. A seller who expected to share returns but not to authorize an IRS request can slow the file at the worst moment. The request belongs in the letter of intent's list of diligence items. See what lenders need to finance an acquisition.
Which returns the lender will ask about
Transparent's SBA checklist asks for two to three years of business tax returns and the same for each owner of 20% or more, alongside the P&L, balance sheet, debt schedule and personal financial statements. Those are the returns a lender will usually verify. The 4506-C is usually signed at application and signed again if the first one ages out; for an SBA loan the verification must be complete before disbursement.
The lender package Transparent builds, financing model, lender presentation, blind teaser and underwriting memo, is built in a day once the documents are in, and flags the returns that will need explaining, such as an amendment or a year on extension, before a lender finds them.

Common questions
- Is signing Form 4506-C the same as giving the lender my returns?
- No. You still provide the returns. The 4506-C lets the lender confirm them against the IRS's own record, and it covers only the years and return types listed on the form.
- Does the lender see my whole tax history?
- Only the transcripts for the tax years and form types written on the form, sent to the verification participant named on it.
- Why did the lender ask me to sign it again?
- The IRS must receive the form within 120 days of the signature, so an older signature may have lapsed. A new form is also needed if a name, address or year was wrong, or a new year's return has been filed.
- My latest return isn't filed yet. Can the loan still close?
- Often, with the filing extension and the latest financial statements, depending on the lender and the timing. The lender will verify the years that are filed and may re-pull once the new return is processed.
- Does the seller have to sign a 4506-C when I buy a business?
- Commonly, yes. The loan is sized on the target's returns, and an SBA lender must verify them with the IRS before it disburses.
