Self-employed veterans and service members often hit an unexpected step when applying for a VA loan: the lender asks for a letter from a CPA. VA loans, guaranteed by the U.S. Department of Veterans Affairs, are known for flexible terms — no down payment, no private mortgage insurance — but they still require clear, verifiable proof of income. For a borrower whose income comes from a business rather than a W-2, that proof isn’t always straightforward.
If you’re new to these documents, it helps to first understand what a CPA letter is and why lenders rely on it.
A CPA letter helps close that gap. It gives the underwriter independent confirmation that the borrower’s business is real, active, and producing the income shown on the tax returns. This guide explains why VA lenders request these letters, what they can and cannot say, and the VA-specific factors — like residual income and entitlement — that shape how the letter is used.
Why Self-Employed Veterans Face Extra Documentation on VA Loans
VA underwriting is designed to confirm that a borrower can sustain a mortgage over the long term. For a W-2 employee, pay stubs and a verification of employment usually settle it. For a self-employed veteran, income is tied to a business — so the underwriter has to assess the health and stability of that business, not just a paycheck.
Under VA guidelines, a borrower is generally treated as self-employed if they:
- Own 25% or more of a business
- Earn income as a sole proprietor, partner, or independent contractor
- Receive substantial 1099 or non-W-2 income
For these borrowers, lenders typically look for two years of self-employment history, personal and business tax returns, and year-to-date profit-and-loss support. A CPA letter is where much of this comes together in a single, professional attestation.
The same principles apply to any CPA letter for self-employed borrowers, whatever the loan program.
VA-Specific Factors That Shape the CPA Letter
This is where a VA loan differs from other mortgage programs. The requirements behind a conventional mortgage CPA letter and the FHA loan CPA letter guidelines each center on different underwriting concerns — while VA loans add their own, covered below. Three VA features directly affect how a CPA letter is used:
Residual income. The VA requires borrowers to have a minimum amount of discretionary income left over each month after major expenses — a requirement unique to VA loans that scales with region and household size. When a self-employed veteran’s income is uneven, underwriters lean harder on documentation like a CPA letter to confirm the income used in that residual-income calculation is reliable.
Entitlement and the Certificate of Eligibility (COE). VA entitlement determines how much the VA will guarantee. It doesn’t change what a CPA verifies, but it does mean the income figures behind the loan need to be solid — because the VA is backing the guarantee.
The VA funding fee and zero-down structure. Because VA loans often require no down payment, the “source of down-payment funds” question that dominates conventional and FHA files matters less here. Instead, the CPA letter usually focuses on business existence, income stability, and — where relevant — whether drawing funds for closing costs or reserves affects the business.
When a VA Underwriter May Request a CPA Letter
Even when an automated system approves the loan, an underwriter may still ask a CPA to:
- Confirm business existence and ownership percentage
- Verify how long the borrower has been self-employed
- Clarify the business structure (LLC, S-Corp, sole proprietorship, partnership)
- Support the legitimacy of income shown on filed returns
- Explain a year-to-year change in business income
A CPA letter can also be requested when automated findings are borderline and the underwriter needs a compensating factor to strengthen the file.
What a CPA Letter Can — and Cannot — Say
A CPA letter is not a guarantee, and it does not replace tax returns. Under AICPA professional standards, a CPA must keep the letter factual and based on records they have actually reviewed. A properly written letter can confirm:
- Length of self-employment
- Entity type and ownership percentage
- That the CPA prepared or reviewed the borrower’s tax filings
- Historical revenue patterns without forecasting the future
- Internal consistency between returns and business financials
It cannot:
- Guarantee future income or business success
- State that a borrower is “financially sound” as an opinion
- Promise the borrower’s ability to repay
A compliant letter focuses on facts and history, not predictions.
Key Elements a VA-Focused CPA Letter Should Include
- CPA credentials — name, license number, firm, and contact details
- Borrower and business details — legal name, entity type, ownership percentage, length of self-employment
- Documented verification — which records the CPA relied on (tax returns, P&L, balance sheet, bookkeeping)
- Factual income statement — consistent with filed returns, no projections
- Professional-standards language — clear that the letter is factual and not a guarantee
Documentation VA Lenders Usually Require Alongside the Letter
A CPA letter supports — but does not replace — the standard VA documentation set. Self-employed veterans should still expect to provide personal and business tax returns (usually two years), year-to-date profit-and-loss statements, business bank statements, and business formation documents. The CPA letter ties these together and gives the underwriter a professional point of reference.
When a CPA Letter Helps Most on a VA Loan
A CPA letter tends to make the biggest difference when:
- The borrower owns multiple businesses
- Business income fluctuates year to year
- The business was recently restructured or reorganized
- Automated underwriting returns borderline findings
- The underwriter needs added confidence in the income used for residual-income qualification
