Self-Employed? Here’s How Mortgage Lenders Calculate Your Income
“My business brought in $300,000 last year. Why isn’t the lender using that as my income?”
I hear versions of this question often. When you work for yourself, the money your business collects, the income on your tax return, and the income a lender uses to qualify you can be three different numbers.

Here’s how the calculation works.
Start with profit, not total sales
For a traditional mortgage using tax returns, lenders generally look at what your business earns after business expenses, then make adjustments allowed by the loan program.
If you file a Schedule C, your net profit is typically the starting point. If you own an S corporation or partnership, the analysis can include wages, your share of business earnings, and whether those earnings are available to you.
Simply transferring money from your business account to your personal account doesn’t automatically create qualifying income.
Some deductions can be added back
Your taxable profit isn’t always the final number. Certain deductions, such as eligible depreciation or business use of your home, may be added back when calculating mortgage income.
But lenders cannot add back every expense just because it lowered your tax bill. Ordinary operating expenses generally still count against your business income.
Here’s a simplified Schedule C example:
Annual business revenue: $250,000
Business expenses: $170,000
Net profit: $80,000
Eligible depreciation added back: $12,000
Adjusted annual income: $92,000
Divided by 12, that equals approximately $7,667 per month before any other required adjustments or review of prior years.
Your income trend matters
Lenders often review two years of tax returns, although some borrowers qualify with one year under specific guidelines.
If your adjusted income was $80,000 one year and $100,000 the next, a two-year average would equal $90,000 annually, or $7,500 monthly—assuming that approach meets the program’s requirements.
Declining income needs closer review. A lender generally cannot average an older, stronger year with a weaker recent year and ignore the decline. We need to understand what changed and whether the income has stabilized.
Your business structure changes the calculation
An LLC is a good example. “LLC” alone doesn’t tell me how to calculate your income because LLCs can file taxes in different ways.
For corporations and partnerships, ownership percentage, business cash flow, and access to earnings can affect what we can use. We also have to avoid counting the same income twice.
Get your income reviewed before you shop
A successful business can still have a complicated mortgage calculation. That’s why I recommend reviewing your complete tax returns early, along with current business financials when needed.
My job is to understand how your business works, identify the income we can document, and help you build a realistic buying plan.
