Gross Income vs Net Income for a Mortgage
Why lenders use gross income for wage earners but net income for self employed borrowers, and how that difference changes what you can borrow.
Updated 2026-08-21| Applies to: Employees, business owners and anyone with a mix of both.
The short answer
For employees, lenders use gross income before taxes and deductions. For self employed borrowers, they generally use net income after business expenses as reported on tax returns, with certain non cash deductions such as depreciation added back. That is why two people with identical deposits can qualify very differently.
The split in one table
| Borrower type | Starting figure | Common adjustments |
|---|---|---|
| W2 employee | Gross pay before taxes | Variable pay averaged over a history period |
| Self employed | Net profit from tax returns | Add back depreciation, depletion and certain one time expenses |
| Mixed | Both, evaluated separately | Combined after each is calculated under its own rules |
Why write offs cut both ways
Deductions that lower your tax bill also lower the net income a mortgage uses. Non cash deductions such as depreciation are typically added back because no money left the business. Real cash expenses generally are not.
Alternatives when returns understate the business
Bank statement and other non QM programs calculate income from deposits rather than returns. They usually carry different pricing and down payment expectations, so the comparison should be run both ways.
If your tax return does not look like your bank account, that is a solvable problem, not a dead end. I can compare the agency calculation against a bank statement approach so you can see both outcomes.

Common mistakes to avoid
- Assuming revenue is income
- Filing aggressively in the year before applying without running the mortgage math first
