A CPA letter for a mortgage is a brief attestation from a licensed CPA confirming that a borrower is self-employed, the business is currently active, and the income documentation is accurate. Most lenders require it on bank statement and P&L loan programs. It does not replace a profit and loss statement and does not by itself prove income.
What is a CPA letter for a mortgage?
A CPA letter — also called a self-employment verification letter or accountant letter — is a one- to two-page document signed by a licensed Certified Public Accountant that confirms three things:
- The borrower is self-employed (sole proprietor, LLC member, S-corp owner, or partner)
- The business is currently active and operating
- The CPA has professional knowledge of the borrower's business — typically as their accountant or tax preparer
It is not a financial statement and does not by itself prove income. It supports the income documentation — bank statements, a P&L, or tax returns — already submitted. Without this attestation, underwriters have no professional confirmation that the business is real and ongoing.
When does a lender require a CPA letter?
CPA letters are most commonly required in four situations:
- Business bank statement loans. When a borrower uses business deposits to qualify, the lender applies an expense ratio to gross deposits to arrive at qualifying income. A CPA-prepared P&L or CPA letter can reduce that ratio and increase the income the lender counts.
- P&L Only programs. Lenders offering P&L-only qualification (no tax returns, no bank statements) require the P&L to be prepared and signed by a CPA, EA, or licensed tax professional.
- Conventional loans with short self-employment history. Fannie Mae and Freddie Mac guidelines require a letter from a licensed CPA confirming the business was in operation within 60 days of the loan closing date when the self-employment history is less than two years old.
- Complex self-employment structures. When income comes from multiple entities or includes partnership income, lenders may require a CPA letter to confirm ownership percentages and active status.
What must a CPA letter say for a mortgage?
The table below shows every required element. A letter missing any of these will typically be rejected at underwriting and need to be reissued.
| Required element | What to include |
|---|---|
| CPA credentials | Full name, license number (CPA, EA, or CTEC credential), firm name, address, phone, and email |
| Borrower identification | Borrower's full legal name as it appears on the loan application |
| Business identification | Business name, legal structure (LLC, S-corp, sole prop, partnership), and ownership percentage |
| Business start date | Date established, or the start of the CPA's professional engagement with the business |
| Active status attestation | Explicit statement the business is currently active with no known plans to close |
| Basis for professional knowledge | Nature of engagement: tax preparation, bookkeeping, periodic review, or consulting |
| Signature and date | Original or electronic signature, printed name, license number, and date — within 120 days of closing |
Some lenders add a requirement that the letter state the CPA was not engaged solely for the purpose of the mortgage application. Ask your loan officer whether your lender requires this language.

Who can sign a CPA letter for a mortgage?
The signer must be a licensed financial professional with direct knowledge of the borrower's business. Acceptable signers vary by program:
- CPA (Certified Public Accountant): Accepted on all programs that require a letter. Always the safest choice.
- EA (Enrolled Agent): Accepted on most non-QM programs. An EA is federally licensed by the IRS and their attestation holds similar weight to a CPA's for most non-QM lenders.
- CTEC (California Tax Education Council): Accepted by some California non-QM programs. Outside California, an EA is the closer equivalent.
- Not a bookkeeper or financial planner: The letter must come from a credentialed tax professional. A bookkeeper, financial advisor, or business attorney cannot substitute unless the lender specifically permits it.
If your regular accountant is a bookkeeper rather than a CPA or EA, ask your loan officer for a referral. Many non-QM lenders maintain relationships with CPAs who routinely prepare letters and P&L statements for loan files.
How a CPA letter affects your bank statement loan qualifying income
When a self-employed borrower uses business bank statements to qualify, the lender applies an expense ratio to gross deposits. That ratio reduces the income counted toward qualification. The ratio varies by lender and program.
With a CPA-prepared P&L or CPA letter, some non-QM programs reduce that ratio to as low as 10%. The example below shows what qualifying income looks like under one of those programs:
| Scenario | Monthly deposits | Expense ratio | Qualifying income |
|---|---|---|---|
| With CPA letter (program example) | $20,000 | 10% | $18,000/mo |

Under programs that accept a CPA-reduced expense ratio, a $20,000/month deposit base qualifies as $18,000/month of income — directly raising the loan amount you can support. For borrowers on the edge of qualifying, this is often the deciding factor.
The 10% expense ratio is program-specific and requires the CPA to have prepared both the letter and a current-year profit and loss statement. Not every lender offers this reduction. Confirm the specific expense ratio and requirements with your loan officer before requesting the letter from your CPA.
Borrowers who use personal bank statements (12 or 24 months of personal deposits) do not need a CPA letter. Personal bank statement programs apply a 0% expense ratio to deposits by default — there are no business expenses to factor out.

FAQ
Does a CPA letter for a mortgage have an expiration date?
Yes. Most lenders require the letter to be dated within 120 days of closing. A letter older than four months will typically be rejected and need to be reissued.
Can an enrolled agent sign a CPA letter for a mortgage?
Some programs accept an enrolled agent (EA) or CTEC-registered tax preparer in place of a CPA. Certain non-QM P&L programs explicitly allow it. Verify with your loan officer before requesting the letter from an EA.
Is a CPA letter the same as a profit and loss statement?
No. A CPA letter is a brief attestation confirming your business is active and your self-employment status. A CPA-prepared P&L statement is a detailed financial document showing income and expenses. Lenders may require both.
Do I need a CPA letter for a bank statement loan?
Not always, but getting one reduces the expense ratio applied to your deposits. Without a CPA letter, lenders apply a program-specific expense ratio to gross deposits. With a CPA letter or CPA-prepared P&L, some programs reduce that ratio to as low as 10%, directly increasing your qualifying income.
What if my CPA refuses to write a mortgage letter?
Ask your loan officer for a referral to a CPA who regularly works with mortgage borrowers. Alternatively, consider a personal bank statement program (12 or 24 months of personal deposits), which applies a 0% expense ratio and does not require a CPA letter.
How long does it take to get a CPA letter for a mortgage?
Typically 2–5 business days if your CPA has current business records. If a P&L needs to be prepared or updated first, allow 1–2 weeks. Request it early — before you are under contract — to avoid closing timeline pressure.
