Home Loans for Business Owners Who Write Off Most of Their Income

Can too many write-offs stop you from getting a mortgage?

Yes, on a conventional loan they can. Take a business owner running a well-established company — a contracting business, a small manufacturing shop, a professional services firm. Revenue is healthy. The business supports a comfortable lifestyle. But when the CPA finishes the tax return each year, the bottom-line net income is a small fraction of what actually moves through the business, because a good accountant's job is to legitimately minimize the tax bill through depreciation, vehicle expenses, equipment purchases, retirement contributions, and every other deduction available.

That's exactly the client we built our non-QM programs around. If you write off most of your income for tax purposes, conventional mortgage underwriting — which relies on your tax returns and the net income left over after those deductions — is going to significantly understate what you can actually afford. You're not a risky borrower. You're a well-advised one. The documentation just needs to catch up to the reality.

Below are the three paths we use most often for business owners in exactly this position — P&L-only, bank statement and asset-based loans — after a quick look at how lenders treat your write-offs.

Do lenders use gross or net income when you're self-employed?

It depends on the loan. Conventional lenders use net income: under Fannie Mae's Selling Guide, the lender analyzes your personal and business tax returns with a cash flow analysis (Fannie Mae's Form 1084 or an equivalent) that starts from the profit left after business expenses, not your gross revenue, and generally looks at a two-year history (Fannie Mae Selling Guide B3-3.5-01). Non-QM programs start somewhere else:

• Bank statement loans start from your deposits, remove transfers and other non-income deposits, and apply an expense factor to business accounts (commonly 50%) instead of using your actual write-offs.
• 1099 income loans: Most 1099-only programs start from your gross 1099 earnings and subtract a fixed expense factor (commonly 10%); some investors use a different factor.
• P&L-only loans use the net profit on a 12-month profit-and-loss statement prepared by an independent CPA or licensed tax preparer, multiplied by your ownership share.

So conventional and P&L-only loans both use a net figure, but a P&L-only loan uses your accountant's current 12-month statement instead of last year's tax return. Bank statement and 1099 loans start from gross and subtract a standard factor instead of your itemized deductions.

Which write-offs get added back?

Only a short list of deductions gets added back, mostly items that don't reduce the cash the business actually produces. For Schedule C income, Fannie Mae requires the cash flow analysis to add back recurring depreciation, depletion, business use of a home, amortization and casualty losses, while non-recurring income is deducted, along with any meals-and-entertainment exclusion reported on Schedule C (Fannie Mae Selling Guide B3-3.6-03). Everything else you spend to run the business — payroll, rent, supplies, advertising, insurance — stays deducted, because that money actually left the business.

That's why a return whose deductions are mostly depreciation and a home office can come out closer to your real earnings on a conventional loan, while one built on real cash expenses usually won't. If you're not sure which describes your returns, ask your loan officer to run the add-backs before you assume you need a non-QM program.

Option 1: Qualify Off a CPA-Prepared Profit and Loss Statement

If your CPA or tax preparer already produces a clean profit and loss statement for your business, our P&L-Only Loans program lets that document do the talking instead of your tax return. We use a 12-month profit and loss statement prepared by your CPA or tax preparer — no tax returns, no IRS Form 4506-C transcript request — with a minimum credit score of 660. Maximum loan-to-value is 90% for loans up to $1,000,000 and 70% for loans up to $3,000,000.

This tends to be the most natural fit for business owners who already have a solid relationship with an accountant and clean books, since the P&L your accountant already produces internally can often be adapted for this purpose with minimal extra work.

Option 2: Qualify Off Bank Deposits

If you'd rather not involve your CPA in preparing a separate document, our Bank Statement Loans program qualifies you using an average of 12 or 24 months of deposits — again, no tax returns or 4506-C involved. Business account deposits are calculated with a 50% expense factor (roughly half of deposits are treated as business overhead, the rest as income), while personal account deposits use a 0% expense factor. Minimum credit score is 640, with loan-to-value up to 90% for loans to $1,000,000, 85% to $2,500,000, and 80% to $5,000,000. This program is available across primary residences, second homes, and investment properties, and includes cash-out options, including delayed financing.

For a lot of business owners, this is the simplest route: you're not asking your accountant to prepare anything new, and the deposit history is something you can pull directly from your bank.

Option 3: Qualify Off What You've Already Built

Some business owners we work with have spent years reinvesting profit rather than paying themselves a large salary — which means their deposit history and tax returns both understate their real financial position, but their investment and retirement accounts tell a very different story. For that borrower, our Asset-Based Qualification program takes eligible assets — checking, savings, stocks, bonds, 401(k), and IRA balances — each counted at the share the investor allows, minus the funds you need to close and any required reserves, then divided by the investor's set number of months (often 60), to produce a monthly qualifying income figure. No employment income documentation is required at all. Minimum credit score is 660, and this program currently applies to primary residences only, with loan-to-value up to 80% for loans to $3,000,000.

Which Option Fits Your Situation?

That last row matters too — if your business structure means you're paid primarily via 1099 rather than running deposits through a business account, our 1099 Income Loans program uses your actual 1099 forms from the last one to two years instead, with a 660+ minimum credit score and LTV up to 90% to $1,000,000 and 85% to $3,000,000. Most 1099-only programs start from your gross 1099 earnings and subtract a fixed expense factor (commonly 10%); some investors use a different factor.

A Structuring Tip Worth Raising Early

How you move money between business and personal accounts can affect which program makes the most sense and how your qualifying income is ultimately calculated. Business account deposits are assessed with a 50% expense factor by default, while personal account deposits use a 0% expense factor. If you currently pay yourself a modest owner's draw and leave most revenue in the business account, it's worth discussing with your loan officer well before you apply — sometimes a small adjustment to how you've been managing accounts over the prior months can meaningfully change your qualifying number under the bank statement program. This is exactly the kind of detail that's easy to miss if you wait until the week you want to make an offer.

Should you amend your returns or wait a tax year?

Talk to your CPA before doing either, because both are tax decisions first and mortgage decisions second. This article isn't tax advice.

Amending. An amended return that reports more income also means more tax owed on that income. Lenders may look closely at returns amended shortly before an application, and some ask for proof that the amended return was filed and the added tax was paid, so ask your loan officer how the lender or investor treats amended returns before you file one.

Waiting a tax year. Claiming fewer deductions on your next return raises the income a conventional lender can count, but it costs you tax on that income, and it doesn't erase the year before: conventional underwriting generally uses a two-year history, and Fannie Mae has the lender measure year-to-year trends in your business's gross income, expenses and taxable income (B3-3.5-01). If a purchase is on the horizon, have that conversation with your loan officer before your next tax filing, not after. For many owners, the faster route is a program that doesn't use the return at all: bank statement, 1099, P&L-only or asset-based.

How do you get mortgage-ready before you apply?

Whichever path fits, a little preparation goes a long way:

1. Talk to your CPA now, not after you find a home. If a P&L-only loan looks like the right fit, ask how quickly your CPA can turn around a trailing 12-month statement.
2. Separate business and personal banking if you haven't already. Clean, separated accounts make bank statement review faster and reduce back-and-forth during underwriting.
3. Keep two years of 1099s if you have them, even if you end up using a different program. They're useful supporting documentation regardless of which path you use.
4. Pull together asset statements. Even if you qualify on income, non-QM underwriting also wants a clear picture of the funds for closing and reserves.
5. Know your credit score before you start shopping. Minimum scores on our self-employed programs range from 640 to 680 depending on the program, and guidelines vary by investor.
6. Run your numbers. Our income calculator estimates bank statement qualifying income from your deposits, expense factor and ownership share. It's not a substitute for underwriting, but it gives you a grounded starting point.

What slows down a self-employed mortgage file?

A few missteps show up again and again in self-employed files, and avoiding them can save weeks:

• Waiting until after finding a home to talk to your CPA. Trailing 12-month P&L statements and organized bank records take time to compile. Starting the conversation early prevents last-minute scrambling once you're under contract.
• Mixing business and personal deposits without a clear pattern. This is the single most common source of underwriting follow-up questions on bank statement files.
• Assuming one lender's guideline is the only option. We underwrite in-house to 25+ non-QM investor programs, and their guidelines for the same program type differ: expense factors, credit tiers and reserve requirements all vary. A file that doesn't fit one investor's bank statement program may fit another's, or a different program entirely.
• Changing your tax filing approach right before applying. Sudden changes to how your business reports income can complicate the very documentation these programs rely on. Talk to your loan officer before making changes if you're planning to apply soon.

What doesn't change across any of these programs?

Regardless of which document does the talking — a P&L, deposits, assets, or 1099s — every one of these is a fully underwritten mortgage. You'll submit a full application with the documentation for your program, and the file goes to underwriting alongside a credit pull, an appraisal on the subject property, and standard title work. We still verify your credit, your assets, and your ability to repay the loan. Alternative documentation replaces tax returns as the primary evidence; it doesn't replace the underwriting process itself, and not every applicant will qualify for every program.
