This post walks through how income documentation usually works for self-employed borrowers on a conventional loan, using the rules the Selling Guide publishes for lenders and the tax pages that explain the forms involved. It doesn't predict what any lender will decide about your file, because that depends on the whole picture.
Why a lender asks for more
Lenders don't get to take income on faith. The CFPB explains that the ability-to-repay rule prohibits most lenders from giving you a mortgage unless they have made a reasonable and good faith determination that you are able to pay back the loan. Under that rule, lenders must generally find out, consider, and document a borrower's income, assets, employment, credit history, and monthly expenses. Source: CFPB, "What is the ability-to-repay rule?"
For a salaried borrower, an employer confirms a lot of that. When you are the employer, the documents have to do that work.
Who counts as self-employed
The IRS says you are generally self-employed if you carry on a trade or business as a sole proprietor or an independent contractor, if you are a member of a partnership that carries on a trade or business, or if you are otherwise in business for yourself, including a part-time business or gig work.

Fannie Mae uses its own test for mortgage underwriting. Its Selling Guide treats a borrower who holds an ownership interest in a business at or above a set threshold as self-employed. Source: Fannie Mae Selling Guide B3-3.5-01
Why tax returns sit at the center
Before you figure self-employment tax and income tax, you figure net profit or net loss by subtracting business expenses from business income. A net profit becomes part of the income on page 1 of Form 1040. A sole proprietor reports business income or loss on Schedule C, and reports Social Security and Medicare taxes on Schedule SE.
That matters because the number a lender generally starts from is your net figure after expenses, as filed. It is usually not your gross sales or the deposits in your account.
The Selling Guide adds a point owners of partnerships and S corporations should know. It says business income reported on an individual Form 1040 may not necessarily represent income that has actually been distributed to the borrower. The lender's job, in its words, is to determine "the amount of income that can be relied on by the borrower" to qualify for the personal mortgage.
The two-year history
The guide generally requires lenders to get a two-year history of the borrower's prior earnings, as a way of showing the income is likely to continue.
There is an exception for newer businesses. Income from less than two years of self-employment may be considered if the most recent signed personal and business federal returns show a full year (12 months) of self-employment income from the current business. The file also has to support a history of prior income at the same or a greater level, in a field with the same products or services, or in an occupation with similar responsibilities.
If you left a job to do the same work on your own, that second path may describe you. If you switched fields entirely, the picture is usually harder.
What a lender typically asks for
Here is the general shape of the request under the Selling Guide. A given lender may ask for more.
- Signed federal income tax returns for the past two years, individual and in some cases business, with all applicable schedules attached.
- In place of copies, a lender may use tax-agency transcripts of your individual and business returns for the most recent two years, as long as they are complete, legible, and include the information from the applicable schedules.
- A signed Form 4506-C lets the lender request tax transcripts. The guide generally requires a separate authorization from each borrower whose income supports the loan, signed by closing. An alternative form or process is allowed if it releases comparable tax-return information and expressly lets the lender share it with the investor. The form is not required when Desktop Underwriter validates all of that borrower's income. Separate personal and business requests may be needed. Form 4506-C is valid for 120 days after completion and signature. Source: Selling Guide B3-3.1-02
- In some cases, copies of the actual schedules, such as Schedules B through F or a Schedule K-1, or the business returns themselves, because transcripts may not give enough detail. Source: Selling Guide B3-3.1-02
The guide also allows one year of returns in some cases, when the business has existed for five years and the borrower has held a qualifying ownership share for five consecutive years, along with other conditions. Business returns may be waived in some cases, too, such as when personal funds cover the down payment, closing costs, and any required reserves, the borrower has been in the same business for five years, and the individual returns show rising self-employment income over the past two years. Whether either applies is a file-by-file question.
What the lender does with the documents
The paperwork isn't the end of it. The guide requires the lender to prepare a written analysis of a self-employed borrower's personal income, including business income or loss on the individual returns, to find the amount of stable and continuous income available. The lender may use Cash Flow Analysis (Form 1084), another analysis that applies the same principles, or an automated income calculator.
When business returns aren't waived, the lender also analyzes the business. The guide lists what that looks at: whether the income recurs, year-to-year trends in gross income, expenses, and taxable income, and the direction of the business over time. Before approving the loan, the lender must consider the stability of your income, the location and nature of the business, demand for what it sells, its financial strength, and its ability to keep generating and distributing enough income.
So two good years can read differently depending on whether the second was higher or lower than the first.
Using business money for the down payment
If you qualify on self-employment income and plan to use business assets for the down payment, closing costs, or reserves, the guide says the lender must do a business cash flow analysis to confirm the withdrawal won't hurt the business. The lender may ask for more than usual, such as several months of recent business account statements or a current balance sheet.
When a business debt appears on your personal credit report, the guide generally counts that monthly payment in your debt-to-income ratio. It may be excluded only if the account has no delinquency history, acceptable records show payments came from company funds, and the lender includes those payments in its business cash flow review. Rules for other loan programs can differ. Source: Selling Guide B3-6-05, Business Debt in Borrower's Name
Getting your own transcripts first
You can look at what the tax agency has on file before a lender does. You can view, print, or download transcripts in your Individual Online Account, or have a tax return or tax account transcript mailed, which takes 5 to 10 calendar days. There is a separate process for a business tax transcript. Source: Get your tax records and transcripts
Use a tax return or record of account transcript when comparing your return and checking schedules. A tax account transcript shows basic account information and does not include the return schedules. A tax return transcript does not show amendments or adjustments made after the original return posted. For those later changes, request a record of account transcript.

Questions to bring to a first conversation
- Here are my last two years of returns. Which number on them do you generally start from?
- My business is a partnership or S corporation. What do you need to see about distributions?
- I've been on my own for less than two years. Does my earlier work history help?
- I want to use some business funds at closing. What statements should I gather?
The BankPricer home page says Jeff "reads your numbers and tells you what he sees," with "No credit pull," and that he reads the notes himself. Source: bankpricer.com home page, read 2026-10-29 You can ask these before you've decided anything.
FAQ
Can I just show bank deposits instead of tax returns?
Not for a conventional loan underwritten to that guide. It builds self-employed income from tax returns or tax transcripts and a written analysis of them. Other loan types may have their own rules.
Will my write-offs lower the income a lender uses?
Usually, yes, because net profit is business income minus business expenses, and that net figure flows to your Form 1040. How each line is treated is part of the lender's written analysis.
When would I see actual loan terms?
After you apply. A lender must deliver or mail a Loan Estimate within three business days after receiving the six pieces of information that make up an application, and when you receive it, the lender has generally not yet approved or denied your application.
One thing to do
Pull your last two years of personal and business returns, with every schedule, and set them next to your tax transcripts. Then send a short note about your business through Get In Touch.
