Your tax returns show low income, but the business is doing well. That's one of the most common problems self-employed New Yorkers bring to a mortgage advisor. Your accountant did the job well: the tax bill is low. But the same return is now the main document a conventional lender uses to decide how much house you can afford.
The good news is that the return isn't the only way to show income. The first step is understanding exactly how a lender reads it, because sometimes the number is better than it looks.
How do write-offs affect mortgage approval?
For a conventional loan, the lender starts with the bottom line of your business: Schedule C net profit for a sole proprietor, or your share of income from a partnership or S corporation. That figure is after every deduction you took. Rent, vehicle, phone, travel, meals, equipment, subcontractors and home office all come out before the lender sees a number.
So a Manhattan consultant who bills strongly but deducts heavily is qualified on what's left. The lender is not judging your business. It is following a rule that ties qualifying income to taxable income.
Which self-employed mortgage write-offs can a lender add back?
Lenders run a cash-flow analysis, often on Fannie Mae Form 1084, that adjusts your return. Certain non-cash or one-time items can sometimes be added back to net income because they didn't actually take money out of your pocket that year.
- Depreciation: the most common add-back, since it is a paper expense rather than cash spent that year.
- Depletion and amortization: similar non-cash items, where they apply.
- Certain one-time or non-recurring losses, if documented as non-recurring.
- Business use of home, in some cases, depending on how it was reported.
Real cash expenses like rent, payroll, fuel and supplies generally stay deducted. Add-backs help at the margins, not across the board.
Example: a Brooklyn photographer with a thin return
A Brooklyn wedding photographer bills steadily through the season and deposits payments into a business account. After deducting camera gear, a studio, travel and an assistant, the return shows a modest profit, and the prior year was lower still. A conventional lender would average the two thin years. A lender may add back depreciation on the gear. If that still falls short, a bank statement program could look at 24 months of deposits instead, apply an expense factor, and qualify on that figure. The photographer's CPA can help decide whether changing future filings is worth it.
How does two-year averaging affect me?
Conventional lenders generally look at two years of self-employment income and average them. If this year was strong and last year was weak, the weak year pulls the average down. If income is declining from one year to the next, a lender may use the lower year or ask for an explanation.
Fannie Mae does allow one year of returns in a narrow case: when the business has existed for five years and you have owned at least 25% of it for five consecutive years, with a cash-flow analysis. That can help an established owner whose most recent year is the stronger one.
Should I stop taking write-offs so I can qualify?
Some borrowers choose to take fewer deductions for a year or two before buying. That raises qualifying income, but it also raises your tax bill, and it only helps if both averaged years reflect it. It is a real tradeoff with real money on both sides.
Talk to your CPA before changing how you file. This site doesn't give tax advice, and the right answer depends on your whole financial picture, not just the mortgage.
What are the alternatives to tax-return income?
If add-backs don't close the gap, non-QM programs measure income differently. They are still underwritten for ability to repay; they just use different documents.
| Option | How income is counted |
|---|---|
| Bank statement loan | 12 or 24 months of deposits, with business deposits reduced by an expense factor |
| 1099 loan | Gross 1099 earnings less a set expense factor, instead of Schedule C net |
| P&L loan | A profit-and-loss statement prepared or signed by a CPA, EA or licensed tax preparer |
| Asset-based | Liquid assets rather than income |
Non-QM rates are typically higher than conventional, and down payment and reserve requirements are usually larger.
Does this matter more in New York?
Often, yes. Prices are high, so the gap between what you earn and what your return shows has a bigger effect on what you can buy. And if you're buying a co-op, the board will usually review your tax returns on its own, even when your lender uses bank statements. Many non-QM lenders also do not lend on co-ops. A buyer with heavy write-offs looking at a co-op may need to plan for both the lender and the board.
The 2026 conforming limit for a one-unit home is $1,249,125 across the five boroughs, Nassau and Westchester. Above that, jumbo documentation rules usually get stricter, which makes the write-off problem sharper.
Common questions
Do lenders use gross or net income for self-employed borrowers?
Conventional lenders use net income after deductions, taken from your tax returns and usually averaged over two years. Some non-QM programs use gross figures instead, such as total deposits or gross 1099 earnings, reduced by an expense factor rather than your actual deductions.
Can depreciation be added back for a mortgage?
Often, yes. Depreciation is a non-cash expense, so lenders commonly add it back during their cash-flow analysis of your return. Depletion and amortization can be treated similarly. Cash expenses you actually paid generally can't be added back.
Do you need tax returns to get a home loan?
For conventional loans, generally yes. Non-QM bank statement, 1099, P&L and asset-based programs can qualify you without using tax returns as the income document. Some may still ask for a tax transcript or other verification, and co-op boards often want returns regardless.
Should I amend my returns to show more income?
That's a tax decision, so talk to your CPA first. Amended returns can raise questions from lenders and may change what you owe. Many self-employed buyers find that an alternative documentation program is a simpler route than changing past filings.
What if my income went down last year?
Conventional lenders look closely at declining income and may qualify you on the lower year or ask for an explanation. If the drop was a one-time event, documentation helps. Bank statement programs look at deposits over 12 or 24 months, which can tell a different story.
Is it worth paying more in taxes to qualify for a mortgage?
Sometimes, sometimes not. It depends on how much extra tax you'd pay, whether two averaged years would reflect it, and the cost difference between conventional and non-QM loans. Your CPA and a mortgage advisor can each run their side of that math.
Will a co-op board accept a bank statement loan?
The board isn't approving the loan type, it's reviewing you. Boards commonly ask for two years of tax returns and a CPA letter from self-employed applicants no matter how the lender documents income. Separately, many non-QM lenders do not lend on co-ops.
What are red flags for mortgage lenders?
Underwriters look for anything that makes income or assets hard to trust: income that drops from one year to the next, large unexplained deposits, overdrafts, new debts missing from your application, recent late payments, and returns that don't match your bank statements or tax transcripts. A big gap between deposits and reported income isn't a red flag by itself, but it does shape which program fits.
Can a mortgage be written off?
The loan itself isn't a deduction, but part of the cost may be. Under IRS rules, home mortgage interest is deductible only if you itemize, and only up to certain loan limits. If you use part of your home for business, that share is handled through the business-use-of-home deduction, which can also affect how a lender reads your return. Ask your CPA how it applies to you.
What is the minimum income required to afford a $300,000 mortgage?
There isn't one number. It depends on the rate, property taxes, insurance, any co-op maintenance or condo charges, your other monthly debts and the program's debt-to-income limit. For self-employed borrowers, the bigger question is which income a lender will count: net income after write-offs, or a figure built from bank statements, 1099s or a P&L. The bank statement calculator can help estimate the second.
