Self-Employed Income Calculation
How lenders calculate qualifying income for self-employed borrowers — and why revenue isn't what actually counts.
Self-employed borrowers face one of the most complicated underwriting processes. Unlike salaried employees, lenders cannot simply look at a paycheck. Instead, they analyze tax returns over multiple years. The challenge is that the income used for mortgage qualification is not always the same as the income shown on tax returns.
Underwriters calculate self-employed income by analyzing net business income, add-backs such as depreciation, business expenses, year-over-year trends, and stability of revenue. Many borrowers assume that because their business generated strong revenue, they will qualify easily. However, lenders often focus on net income after deductions.
For example: a business owner might generate $200,000 in revenue but report only $65,000 in taxable income after deductions. For mortgage underwriting purposes, the lender may qualify the borrower based on that $65,000 figure, not the revenue.
Even more challenging, underwriters look for income consistency. If income drops from one year to the next, lenders may average the two years — or sometimes use the lower year entirely. This is why self-employed borrowers are denied mortgages at higher rates than W-2 employees.
