CPA Letters
A CPA letter is a statement from your accountant confirming details about your business and income. Lenders use these to verify information that other documents alone don’t establish. A CPA letter typically confirms:- You are self-employed in the stated business
- Length of time in business
- Your ownership percentage
- The business is currently operating
- Actual expense ratio (if applicable)
Bank Statement Loans
For bank statement loans, CPA letters and P&Ls are optional but can meaningfully increase qualifying income. Without documentation, lenders apply default expense factors based on industry—often 40-50%. A CPA letter stating your actual expenses are lower can reduce that factor and increase qualifying income. Example on $400,000 annual deposits:
That $100,000 difference substantially increases borrowing power.
A CPA-prepared P&L covering the same period as your bank statements can serve the same function—providing a formal accounting of revenue and expenses that supports the lower expense factor. Some lenders require the P&L to be reviewed or audited rather than simply prepared.
Consider getting a CPA letter or P&L for bank statement loans if:
- Your actual expenses are lower than industry defaults
- Your business type typically triggers high default expense factors
- The lender offers a reduced expense factor with supporting documentation
1099 Loans
For 1099 loans, a CPA letter plays a supporting role. The primary income documentation is your 1099 forms, but lenders often require or request a CPA letter to confirm self-employment status and that the business is currently active. If the lender applies an expense factor to your 1099 income (typically 10-25%), a CPA letter documenting your actual expenses can justify using a lower rate—the same mechanism as with bank statement loans, but less impactful since 1099 expense factors are already modest. A P&L can also be submitted as supplemental documentation, particularly if your 1099 income and bank deposits don’t align closely and you need to explain the discrepancy. Typical CPA letter use for 1099 loans:- Confirms self-employment and business operation (often required)
- Supports a lower expense factor if one is being applied
- Provides supplemental context when 1099 totals and deposits diverge
P&L Loans
For P&L loans, the CPA-prepared profit and loss statement is the primary qualifying document. This is the most CPA-intensive of the four programs—the loan is built around the accountant’s work. The P&L must meet specific lender requirements:
The net profit figure on the P&L becomes the qualifying income base. Because actual expenses are used rather than an estimated factor, borrowers with genuinely low overhead often qualify for more under a P&L program than under bank statement programs.
What lenders look for in the P&L:
A CPA letter is typically submitted alongside the P&L to confirm ownership percentage, years in business, and current operating status.
