Complete 2026 guide covering income calculations, required documents, and Fannie Mae guidelines for sole proprietors, S-corps, and partnerships.

Have you been Googling "self-employed mortgage approval" at 2am, trying to figure out why your accountant's brilliant tax strategy is now working against you?
Getting approved when you're self-employed isn't harder like most people assume. It's just different.
And once you understand what lenders are actually looking for, the whole process makes a lot more sense.
This guide breaks down exactly how Fannie Mae (the organization behind most conventional mortgages) analyzes your income, using real examples with actual numbers.
Whether you're a sole proprietor, run an S-corp, or you're a partner in a business, you'll see exactly how lenders calculate the income they'll use to qualify you.
Need help getting approved for a self-employed mortgage?
The team at Austin Capital Mortgage specializes in working with self-employed borrowers and can help you understand exactly what you qualify for.
Self-Employed Mortgage Requirements: When Do You Need Special Documentation?
If you own 25% or more of a business, lenders treat you as self-employed. It doesn't matter if you also get a W-2 from that business or if it's just a side gig that brings in extra income; once you hit that ownership threshold, you're playing by different rules.
This changes everything about how they verify your income.
Instead of just looking at your W-2 and calling it a day, they're diving into your tax returns, business financials, and profit trends. It's more involved, but it's not impossible. You just need to know what they're looking for.
What Lenders Are Really Looking For
Here's what you need to understand about how your income gets evaluated:
Two Years in Business (Usually)
Lenders typically want to see two years of self-employment history. They need to know your income is stable.
One great year could be a fluke. Two years proves you can consistently run a profitable business.
The exception: If you just started your business last year but worked in the same field for years before, you might qualify with just one year of self-employment.
For example, if you were a marketing director for a company and then started your own marketing agency, that prior experience counts. You'll need to show your income is stable and you know what you're doing.
The Documents Your Lender Will Request
Get these ready before you even apply:
- Two years of complete tax returns (your 1040)
- Business tax returns (Schedule C if you're a sole proprietor, 1120S for S-corps, or 1065 for partnerships)
- K-1 forms (if you have an S-corp or partnership)
- Year-to-date profit and loss statement
- Year-to-date balance sheet
The YTD documents are crucial. Even if you filed great tax returns last year, lenders need to see that your business is still performing well this year.
How They Calculate Your Income
Here's where it gets interesting. Lenders don't just take your "net profit," but they do something called income averaging.
If you made $50,000 in 2024 and $60,000 in 2025, they'll average those two years: ($50,000 + $60,000) ÷ 24 months = $4,583/month. That's your qualifying income.
They also add back certain expenses. Remember that depreciation on your tax return? That's a paper expense; you didn't actually spend that cash. Lenders add it back to your income because it's money you actually have available.
But if your income is going down year over year, that's a red flag. They might only use your most recent year, or worse, they might not be able to approve you at all.

Form 1084: The Behind-the-Scenes Calculator
You won't fill this form out yourself, your loan officer handles it. But it's worth understanding what it does.
Form 1084 is the standardized worksheet lenders use to calculate your actual qualifying income from your tax returns.
It takes your reported income and makes adjustments for things like:
What gets added back:
- Depreciation (because you didn't actually pay this out)
- Amortization
- One-time deductions that reduced your taxable income
What gets subtracted:
- One-time income spikes (like if you sold a piece of equipment)
- Non-recurring items that won't happen again
This is why two people with the same "net profit" might qualify for different mortgage amounts. The devil is in the details of what shows up on your tax return.
Example #1: Sole Proprietor Income Calculation
Let's look at how this works in practice. Meet John. He runs a landscaping business as a sole proprietor.
John's Situation
- Business: Smith Landscaping
- Structure: Sole proprietorship (files Schedule C)
- Years in business: 3+
What do his tax returns show?
2024:
- Net Profit: $45,000
- Depreciation expense: $3,000
- Total income for qualifying: $48,000
2025:
- Net Profit: $50,000
- Depreciation expense: $3,500
- Total income for qualifying: $53,500
How do lenders calculate his income?
The lender adds back that depreciation (remember, it's a paper expense) and averages the two years:
($48,000 + $53,500) ÷ 24 months = $4,229/month qualifying income
The Current Year Check
Even though John's tax returns look great, the lender also requests his current year profit and loss statement. Why? Because they need to make sure his business is still doing well.
John's YTD P&L shows he's averaging $4,280/month this year. That confirms his income is stable and even trending up slightly.
The Result
John gets approved. His income shows a positive trend, and his current business performance backs up what his tax returns promised.
Example 2: S-Corporation Income Verification
S-corps are trickier because your income comes from two places: your W-2 salary and your share of business profits (shown on your K-1). Let's see how this works.
Sarah's Situation
- Business: Thompson Marketing Solutions, Inc.
- Structure: S-Corporation (she owns 100%)
- Income sources: W-2 wages + K-1 distributions
The W-2 Part (Her Salary)
- 2024: $48,000
- 2025: $52,000
- Average: $4,167/month
This part is straightforward, it's regular salary from her own company.
The K-1 Part (Business Profits)
This is where it gets interesting. Sarah's business made profits that she didn't take as salary. These show up on her K-1 form.
2024:
- Business income: $80,000
- Add back depreciation: $6,500
- Add back amortization: $5,000
- Total: $91,500
2025:
- Business income: $92,000
- Add back depreciation: $7,000
- Total: $99,000
K-1 Average: ($91,500 + $99,000) ÷ 24 = $7,938/month
Total Monthly Income
- W-2 income: $4,167
- K-1 income: $7,938
- Total: $12,104/month
The Liquidity Question
Here's something important: when you're using K-1 income, lenders want to make sure that money is actually accessible. If your business profits are sitting in the company account (not in your personal account), they need to verify the business has enough cash to operate.
Sarah's business shows $100,000 in the bank. That's plenty, it proves the business is healthy and the K-1 income is legitimate.
The Result
Sarah qualifies using her full income of $12,104/month. Her W-2 is increasing, her business profits are growing, and she has solid business liquidity. Everything checks out.

Example #3: Partnership Income Documentation
Partnerships work similarly to S-corps, but with a twist; you only get credit for your ownership percentage. Let's see how it works for David.
David's Situation
- Business: Lopez & Greene Consulting, LLP
- Structure: Partnership (he owns 50%)
- Income sources: Guaranteed payments + K-1 share of profits
Guaranteed Payments (like a salary)
Partnerships can pay "guaranteed payments" to partners for their work. Think of it like a salary, but it's reported differently.
- 2024: $20,000
- 2025: $25,000
- Average: $1,875/month
K-1 Income (his 50% Share of Profits)
Since David owns half the business, he gets half the profits on his K-1.
2024:
- His share of business income: $65,000
- Add back depreciation: $6,000
- Add back one-time expense: $3,000
- Total: $74,000
2025:
- His share of business income: $70,000
- Add back depreciation: $6,500
- Total: $76,500
K-1 Average: ($74,000 + $76,500) ÷ 24 = $6,270/month
Total Monthly Income
- Guaranteed payments: $1,875
- K-1 income: $6,270
- Total: $8,145/month
The Liquidity Check
Same deal as with S-corps; if K-1 income is retained in the business, lenders verify the partnership has adequate cash.
David's partnership shows strong cash reserves and retained earnings, so his K-1 income counts in full.
The Result
David qualifies at $8,145/month. His guaranteed payments are increasing, his share of partnership profits is growing, and the business is financially healthy.

| David | Partnership | $8,145 | Approved |
Why Do Self-Employed Mortgage Applications Get Denied?
Even if you have all the right documents, certain situations can cause problems:
Your Income Is Dropping
If your income fell by 20% or more between years, lenders get nervous. They want to understand why. Was it temporary (maybe you took time off for a project)? Or is your business struggling?
Your current YTD profit and loss becomes critical here. If it shows you're back on track, that helps. But if the decline is continuing, you might have issues.
Your Numbers Don't Match
If your tax return says one thing but your K-1 or YTD P&L says something different, that's a problem. Everything needs to line up. Inconsistencies make lenders think something's wrong with your bookkeeping, or worse.
Your Business Doesn't Have Enough Cash
This only matters if you're using K-1 income. If you're claiming $100,000 in K-1 income but your business account has $5,000 in it, lenders will question whether that money is really accessible.
They might reduce or eliminate your K-1 income from the calculation.
You're Missing Current Documentation
Let's say you're applying in July 2026 using your 2024 and 2025 tax returns. Your last return was filed months ago.
Lenders need to see a current P&L showing what's happening this year. Without it, they can't verify your business is still performing well.
You Had a Big One-Time Income Spike
Sold a piece of equipment for $50,000? Great, but lenders won't count that as ongoing income.
If your qualifying income depends heavily on one-time events that won't repeat, your sustainable income might not be enough.

Self-Employed Mortgage Checklist: How to Prepare Your Mortgage Application in 2026?
Want to make the mortgage process as smooth as possible? Here's what to do:
Before you even talk to a lender:
- Get your documents organized: Have your last two years of tax returns, K-1s (if applicable), and current YTD P&L and balance sheet ready to go. Don't make your loan officer hunt for stuff.
- Review your own tax returns: Look at your income trend. Is it going up, staying flat, or dropping? If it's dropping, be prepared to explain why and show how you're turning things around.
- Know your entity type: Understand whether you're a sole proprietor, S-corp, or partnership. Different structures = different documentation requirements.
- Calculate your own income: Don't guess. Use the formulas we covered above and figure out what your actual qualifying income will be. This prevents surprises later.
- Check your business bank balance: If you have an S-corp or partnership, make sure your business has adequate cash reserves. This directly impacts whether lenders can use your K-1 income.
- Update your current financials: If your YTD P&L is from three months ago, update it. Lenders want recent information.
- Talk to your CPA: Before you apply, ask them to review what your income will look like to a mortgage lender. They might spot issues you'd miss.
Be realistic: If your income is declining or you just started your business last year without prior industry experience, you might need to wait, build up more history, or look at alternative loan programs.
Self-Employed Mortgage Approval: Key Takeaways
Getting a mortgage when you're self-employed isn't rocket science, but it does require more documentation and a solid understanding of how lenders view your income.
The key takeaways for self-employed mortgage approval:
- Lenders need two years of history (with rare exceptions for one year plus prior experience)
- They average your income over both years unless it's declining
- They add back non-cash expenses like depreciation
- Current YTD financials are just as important as your tax returns
- If you have an S-corp or partnership, business liquidity matters
The biggest mistake self-employed borrowers make? Assuming their "net profit" on their tax return is what lenders will use. It's not.
Between add-backs, averaging, and entity-specific rules, your qualifying income might be higher or lower than you think.
Do yourself a favor: before you start house shopping, sit down with your documents and calculate your actual qualifying income using the methods we covered here.
Or better yet, talk to a mortgage professional who actually understands self-employment income (not all of them do).
When you understand the process and come prepared with the right documentation, getting approved is easy. You just need to play by the rules.

Why Work With Self-Employed Mortgage Specialists?
Fannie Mae's guidelines for self-employed borrowers exist for a good reason. They want to make sure you have stable, sustainable income that'll be there for years to come.
It's not about making things difficult; it's about protecting both you and the lender from a mortgage you can't afford.
The three examples we walked through, John the sole proprietor, Sarah with her S-corp, and David the partner, show how the process works in real life.
Different business structures, different income sources, but the same basic principles apply: stable or growing income, proper documentation, and current proof that your business is still performing.
If you take nothing else from this guide, remember these things:
- Your "net profit" isn't your qualifying income, lenders adjust it
- Two-year averaging is standard for stable/growing income
- Current YTD financials matter just as much as
tax returns
- Business liquidity affects K-1 income usability
- Being organized and proactive makes everything easier
The self-employed mortgage process isn't mysterious once you understand what lenders are looking for.
Come prepared with clean documentation, stable income trends, and realistic expectations, and you'll be fine.
And if you're working with a loan officer who seems confused by your tax returns or can't explain how they're calculating your income, find someone who
specializes in self-employed borrowers. Not everyone has the expertise, and it makes a huge difference.
