Self-Employed and Applying for a Mortgage? Start Here
Breaking down business income and tax documents so you can feel confident and organized.
If you are self-employed, you may wonder how lenders figure out your income for a mortgage. Unlike a regular paycheck, self-employment income can come from many sources, and the paperwork can seem complicated.
This article aims to simplify the process. We’re breaking down the different types of businesses and the documents lenders need so you can see exactly what counts as income. By understanding how your business structure affects the process, you can stay organized, provide the correct documents the first time, and help ensure the income on your tax returns is clearly and accurately reflected. Consider this a roadmap for getting your finances in order before applying for a loan. It’s all about giving you confidence and clarity so the process is straightforward and less stressful.
Let’s dive in.
Sole Proprietorship: The Simple Start
A sole proprietorship is the simplest type of business. One person owns it, and all the income and expenses are reported directly on the personal federal tax return, Form 1040, on Schedule C. This structure is common for small businesses, freelancers, and independent contractors.
For underwriting, you’ll need two years of personal tax returns with all schedules. Make sure to include both pages of Schedule C. The second page is important because it lists details like miles driven for business, if any were reported. Those miles connect to auto expenses and depreciation, which can be added back to income. Including all pages upfront helps avoid delays and keeps the process moving smoothly.
Partnerships: Sharing the Business
A partnership is a business owned by two or more people. The business reports its profits and losses on Form 1065, and each partner’s share is shown on a Schedule K-1. That K-1 flows to the personal federal tax return, Form 1040, usually on Schedule E. Partners typically do not receive a regular salary; instead, they take distributions of the profit. Each partner pays taxes individually on their share of the income.
You’ll need two years of personal tax returns, two years of partnership returns (Form 1065), and all schedules. Be sure to include all K-1s. These forms not only verify the income reported on the personal return, but they also show the percentage of the business each partner owns. If the business pays a wage, include the W-2s as well.

S-Corporations: How Income Flows to You
An S-Corporation is a business that chooses special tax treatment so that income, losses, deductions, and credits pass through to its shareholders. The business files Form 1120-S, and shareholders receive a Schedule K-1, which shows their share of income or loss and their ownership percentage. Unlike partnerships, shareholders who work in the business usually receive a W-2 wage, and any additional profits are distributed and reported on the K-1. Both the wage and the distributed profits are reported on the personal tax return.
You’ll need two years of personal tax returns, two years of S-Corp returns (Form 1120-S), all K-1s, and any W-2s received.
C-Corporations: Income and Dividends
A C-Corporation is taxed separately from its owners. The corporation files Form 1120, and the business itself pays taxes on its profits. Owners may receive a W-2 wage if they work for the company, and any dividends are reported separately on the personal tax return. Profits that are not distributed stay with the corporation and are taxed at the corporate level.
You’ll need two years of personal tax returns, two years of corporate returns (Form 1120), and any W-2s received. Dividends reported on the personal return should also be included when reviewing income.
Profit and Loss Statements and Balance Sheets
Some loan programs may also ask for a year-to-date profit and loss statement. For most business types, such as partnerships, S-Corps, and C-Corps, they might also request a balance sheet. Don’t let that sound overwhelming. These documents are not used to calculate qualifying income on their own, and they do not require auditing, which can be expensive. Instead, they help show that the income reported to the IRS over the last two years is continuing and, in some cases, even increasing. Working closely with your loan officer can make the process much easier and less stressful.
A Few Things to Remember
With all these documents in hand, the process can feel more manageable. The key is knowing exactly what lenders need and providing complete returns and schedules upfront. Keeping everything organized helps avoid delays and makes it easier to verify income and ownership information.
When providing tax returns, skip the state returns. Only federal returns are needed, and all pages must be included. Do not black out any data. We need to be able to read everything. If you own multiple businesses, include returns for each one, even if one company owns or is owned by another. All K-1s are critical, so do not leave them out.
If you have businesses listed on Schedule E of your personal return, include the K-1s for each. The only time you do not need to provide the business returns is if you own less than 25 percent of the company. At 25 percent or more, the full business returns and schedules are required.
