This is written for loan officers, processors, and the CPAs who get these requests — not for borrowers. If you are a borrower looking for what the letter has to say and a sample, read CPA letter for a mortgage instead.
Why these requests get refused
A CPA letter request fails for one reason more than all the others combined: the form asks the accountant to vouch for something they have no basis to vouch for. Ask a CPA to confirm a borrower "is able to meet the proposed obligation" and you will get a no, correctly. Ask them to confirm the business was active on a date and that they have prepared its returns since 2019, and you will usually get a letter.
Professional guidance in the accounting field cautions members about third-party verification requests, specifically where the wording implies assurance the accountant has not performed. A CPA who prepares a tax return has not audited or reviewed the financial statements. A letter that reads as though they have is a liability they are right to refuse — and an underwriter reading it closely will treat an over-reaching letter as a reason for more scrutiny, not less.
The practical consequence for a loan file: the wording of the ask determines whether you get the document, and a generic lender template is the least likely version to come back signed.
What underwriting actually needs
Every element below is a verifiable fact the accountant already holds. None is a forecast or an opinion.
| Element | Why underwriting wants it |
|---|---|
| CPA name, license number, firm, contact | Lets the lender verify the credential independently |
| Borrower legal name as on the application | Ties the letter to the file without a name-mismatch condition |
| Business name, structure, ownership percentage | Supports the income calculation and entity analysis |
| Business start date or engagement start date | Drives the two-year self-employment test |
| Active-status attestation as of a stated date | The core requirement on most programs |
| Basis of professional knowledge | Establishes the CPA is not writing about a business they barely know |
| Signature, printed name, license number, date | Letters older than 120 days are routinely re-requested |
How to word the request so it comes back signed
- Name the document. "Existence and status letter," "expense ratio letter," "CPA-prepared P&L," or "business funds letter" are four different asks. A request that does not say which one gets the wrong one.
- List the facts, not the conclusion. Send the element list. Do not send a conclusion for the CPA to endorse.
- Invite their own wording. Underwriters accept a CPA's language when it covers the elements. A letter the CPA drafted is a letter the CPA signs.
- Strip solvency and ability-to-repay language. If your template contains it, remove it before sending. It is the single most common cause of refusal.
- Give the deadline and the date that matters. Active-status attestations are date-specific, and a letter dated too early gets reissued.
- Expect a fee. Many firms charge for these. Telling the borrower up front prevents a stall mid-file.
When the CPA still says no
- Check whether the credential is the blocker. Some programs accept an enrolled agent or a CTEC-credentialed preparer. Confirm against the specific program before assuming they are interchangeable.
- Substitute a CPA-prepared P&L. Some accountants will prepare a P&L — ordinary professional work — while declining an attestation. On several programs the P&L is the stronger document.
- Re-document the file. Personal-account qualifying, a different statement period, or a different program may remove the need entirely.
- Do not re-send the same form. Pressing a reluctant CPA with the identical template, or shopping for an accountant who will sign what the first one would not, produces a weaker file.
CPA audit and licensing questions
A separate question reaches us often enough to answer here: whether a mortgage lender's own financial statements require a CPA audit. That is a licensing and net-worth matter set by each state regulator and by the agencies, and it varies by state, by license type, and by whether the entity is a lender or a broker. It is not a loan-file question and it is not answered by anything on this page — check your state regulator's current requirements and your agency approvals directly, because the thresholds change.
