The short answer: Lenders qualify most self-employed borrowers on the income shown on their last two years of tax returns, not on what the business actually brings in. Some write-offs, like depreciation and business use of your home, get added back. Most others don't. If you plan to buy in the next year or two, talk to your tax preparer and your mortgage broker together before you file. One return with a little less in write-offs can raise your buying power more than a year of saving.
How do lenders look at self-employed income?
Under Fannie Mae's rules, the standard is two years of personal tax returns, plus business returns where required. Only one year is allowed when the business has existed for five years, you've owned at least 25% of it for those five years, and the lender completes a cash-flow analysis (Fannie Mae B3-3.5-01).
The lender also orders your tax transcripts directly from the IRS, using Form 4506-C, so the returns you hand over must match what you filed (Fannie Mae B3-3.1-02). There's no "lender version" of a tax return.
Which deductions do lenders add back?
For a sole proprietor reporting on Schedule C, Fannie Mae's cash-flow analysis adds back several non-cash or one-time deductions (Fannie Mae B3-3.6-03):
Schedule C deductions: what a lender adds back
| Added back to your income? | |
|---|---|
| Depreciation | Yes |
| Depletion and amortization | Yes |
| Business use of your home | Yes |
| Casualty losses | Yes |
| Everyday expenses (supplies, fuel, phone, wages) | No These reduce qualifying income |
| One-time income | Subtracted from your income |
Most other expenses you deduct, from supplies to your crew's wages, lower the income a lender can use. That's correct for taxes and expensive for a mortgage.
What if my income went down last year?
Lenders compare your two years. Rising or steady income is generally averaged. If it declined, Fannie Mae's guidance is to use the lower, more recent figure, averaged over 12 months, and the lender has to document that the income has stabilized (Fannie Mae income calculator FAQ). A sharp drop can also raise questions about the business itself, so a short letter explaining it, such as a one-time equipment purchase or a slow season, helps.
What if my tax returns don't tell the real story?
Bank-statement loans qualify you on 12 or 24 months of deposits instead of tax returns. A typical program applies an expense factor, often 50% of business deposits by default, unless your CPA documents a lower one (Angel Oak, as one example). These are non-QM loans: they generally cost more and may carry a prepayment penalty, which I'll always tell you up front. They're a good tool, but planning your returns a year ahead often gets you a better loan.

Derek\'s take
A large share of my clients are self-employed, and the pattern is always the same: great business, conservative tax return, surprised at the pre-approval number. The fix is easy if we start early. Call me before your tax preparer files, and we'll find the balance between saving on taxes and qualifying for the home you want.
Frequently asked questions
How many years of tax returns do I need if I'm self-employed?
Usually two. One year can work if the business has existed for five years and you've owned at least 25% of it that long.
Does depreciation hurt my mortgage application?
No. Lenders add depreciation back to your income in their cash-flow analysis.
Can I get a mortgage without tax returns?
Yes, through a bank-statement (non-QM) loan, typically using 12 or 24 months of deposits. Expect a higher rate than a conventional loan.
Can I amend my returns to show more income?
Amended returns can be used in some cases, but lenders look at them closely and you'll owe the additional tax. Talk to me and your CPA first.
