- Conventional loans usually average two years of net income from your tax returns, with certain non-cash expenses added back.
- Bank statement loans use deposits minus an expense factor, often around 50%, sometimes lower with a CPA letter.
- 1099 and P&L programs start from different documents and can produce very different numbers.
- Comparing methods side by side is often the clearest way to find the one that shows your real income.
If you are self-employed, the most important number in your mortgage file is not your revenue. It is the qualifying income the lender calculates from your documents. Understanding how lenders calculate self-employed income helps explain why two lenders can look at the same business and reach very different answers.
The good news is that there is more than one method. This guide walks through each approach in plain English, with illustrations, so you can see which one is most likely to reflect what you actually earn.
How lenders calculate self-employed income vs W-2 pay
When you have a W-2 job, a lender can read your pay stub and know your income. When you own a business, your income depends on revenue, expenses, deductions, and how your business is structured. Lenders need a repeatable way to turn all of that into one monthly figure.
Each loan program uses its own formula. Some start with your tax return. Others start with your bank deposits, your 1099s, or a professionally prepared profit and loss statement. Some do not look at personal income at all.
Method 1: Tax returns (conventional and government loans)
This is the traditional approach. The lender reviews your personal and, if applicable, business tax returns, usually for the last two years, and averages your net income.
What gets added back
Lenders typically add back certain non-cash or one-time expenses because they reduce taxable income without reducing cash in your pocket. Common add backs include:
- Depreciation
- Depletion
- Amortization
- Business use of home, in some cases
- Certain one-time, nonrecurring losses, when documented
Trends matter
If your income dropped from one year to the next, many lenders will use the lower year or ask for an explanation. If income rose, they usually still average the two years. This is why a growing business can look smaller on paper than it really is.
Illustration
Illustration only, round numbers: your Schedule C shows net profit of $60,000 one year and $80,000 the next, plus $10,000 of depreciation each year. Added back and averaged, the lender's figure would be about $80,000 per year, or roughly $6,667 per month. If your write-offs are large, this method can understate your earning power. Here is more on how tax write-offs affect your mortgage.
Method 2: Bank statements
Bank statement loans skip the tax return and look at the money flowing into your accounts. Lenders usually review 12 to 24 months of personal or business statements.
How the math typically works
For business accounts, the lender totals eligible deposits and applies an expense factor, often around 50%, sometimes lower with a CPA letter. For personal accounts, many lenders count eligible deposits at a higher share because business expenses have already been paid. The total is then divided by the number of months reviewed.
What gets excluded
Transfers between your own accounts, loan proceeds, refunds, and unusual one-time deposits are often removed. Large deposits that do not match your normal pattern may need an explanation.
Illustration
Illustration only, round numbers: 12 months of business deposits total $300,000. With a 50% expense factor, the lender counts $150,000, or $12,500 per month. You can try your own numbers with our bank statement income calculator.

See if you qualifyMethod 3: 1099 income
If you are paid as an independent contractor, a 1099 program starts with the gross income reported on your 1099 forms. Many lenders apply an expense factor that varies by lender, then divide by the months reviewed. Some use one year of 1099s and some average two.
This method can work well for commissioned agents, consultants, and other contractors whose tax returns show large deductions. Our 1099 mortgage guide covers it in detail.
Method 4: Profit and loss statement
A P&L program uses a profit and loss statement prepared or signed by a CPA, enrolled agent, or licensed tax preparer. Lenders generally qualify you on the net profit shown, often over 12 or 24 months, and many ask for business bank statements to support the revenue.
The advantage is that it uses your actual expense ratio rather than a standard factor. If your real expenses are lower than a lender's default bank statement factor, a P&L can show more income.
Method 5: Rental cash flow and assets
Some programs do not calculate your personal income at all.
DSCR loans
A DSCR loan looks at whether the investment property's rent covers its housing expense. Your business income is generally not the deciding factor, which can help investors with complex returns.
Asset based loans
Asset based programs, sometimes called asset depletion, convert eligible liquid assets into a monthly income figure using a lender formula. This can fit owners with significant savings or investment accounts but uneven income.
Side by side comparison
Here is a simplified view of how each method treats your income. Actual guidelines vary by lender and program.
| Method | Starting point | How income is reduced | Often fits |
|---|---|---|---|
| Tax returns | Net income on returns | Already net; some add backs | Owners with strong reported income |
| Bank statements | 12 to 24 months of deposits | Expense factor on business accounts | Owners with large write-offs |
| 1099 | Gross 1099 income | Expense factor that varies by lender | Independent contractors |
| P&L | CPA-prepared net profit | Your actual expenses | Growing or restructured businesses |
| DSCR | Property rent | Compared to housing expense | Real estate investors |
| Asset based | Eligible liquid assets | Lender formula | Asset-rich, income-light borrowers |
Other factors lenders weigh
Income is only part of the picture. Lenders also look at:
- Time in business: about two years is typical; some lenders consider less, especially if you stayed in the same field.
- Credit: many programs start around 620.
- Debt to income ratio: some lenders allow up to around 50% with compensating factors.
- Reserves: funds left after closing can strengthen a file.
- Down payment: requirements vary by lender and program.
Non-QM programs, including bank statement, 1099, P&L, DSCR, and asset based loans, are not available in all states.
How to find the method that fits you
Start by gathering what you already have: recent tax returns, 12 to 24 months of bank statements, any 1099s, and a current P&L if your CPA prepares one. With those in hand, a broker can run your numbers through several methods and see which one reflects your real income.
Matador works with 150+ wholesale lenders, and each one calculates income a little differently. That variety is useful. It means the answer you got from one lender is not necessarily the final word. Pricing depends on the file, so we compare real offers before recommending anything.
One more note: do not change your tax approach just to qualify. That is a conversation for your CPA. We are not tax advisors.
Frequently asked questions
How do lenders calculate income for self-employed borrowers?
It depends on the program. Conventional loans usually average two years of net income from tax returns, while non-QM programs may use bank deposits, 1099s, a CPA-prepared P&L, rental income, or assets. Each method can produce a different qualifying number.
Do mortgage lenders use gross or net income for self-employed borrowers?
Most methods ultimately use some version of net income. Tax return loans use net profit with certain add backs, and bank statement or 1099 programs apply an expense factor to gross figures. The exact approach varies by lender.
What expense factor do lenders use on bank statements?
For business bank statements, the expense factor is often around 50%, sometimes lower with a CPA letter. Personal account statements are often treated differently. Each lender sets its own rules.
Does depreciation count as income for a mortgage?
On tax return based loans, many lenders add depreciation back to your income because it is a non-cash expense. Other add backs can include depletion and amortization. Your loan officer can review your returns to see what applies.
