Your CPA told you to write everything off. Your lender said you don’t make enough. Both are right.

The write-off paradox: two numbers, one problem

Every self-employed mortgage problem I’ve seen in 28 years comes down to the same split: your business produces one number, and your tax return reports a much smaller one. Your CPA’s job is to make that second number as small as the law allows — vehicle expenses, the home office, equipment under Section 179, accelerated depreciation, retirement contributions, health premiums, the mileage log you finally started keeping. Every one of those deductions saves you real tax money. Your CPA is doing exactly what you pay them for.

Then you sit down with a bank, and the loan officer flips straight to the bottom line of your Schedule C or your K-1 and reads the small number out loud like it’s the whole story. By their guidelines, it is. Traditional underwriting starts from net taxable income and works backward through a cash-flow analysis. A few “paper” deductions get added back — depreciation, depletion, amortization, one-time casualty losses, sometimes business use of home — because they reduce your taxes without reducing the cash in your pocket. But most write-offs don’t come back. The meals, the truck, the marketing, the new equipment — in the underwriter’s math, that’s income you don’t have.

So you get the conversation thousands of Michigan business owners have had: “Your business deposited $20,000 a month, but your return shows $68,000 for the year, so that’s what we can use.” The bank isn’t lying to you. The CPA didn’t make a mistake. Both professionals did their jobs correctly — they just optimized for opposite outcomes. Minimizing taxable income and maximizing qualifying income are competing goals, and nobody warns you about the trade until you’re sitting in front of a declined application.

So what’s the smart play? It is not to stop deducting and hand the IRS extra money — and it’s usually not amending old returns to show more income, which tends to raise more underwriting questions than it answers. The smart play is coordination. If a home purchase is twelve to twenty-four months out, your CPA and your broker should be looking at the same calendar: which deductions are paper (depreciation comes back at underwriting; the new truck mostly doesn’t), whether a major Section 179 purchase can wait a filing year, and what your next return needs to show if you want a full-documentation loan. And if the returns are already filed and already lean? Then we stop fighting the tax return entirely and document the file a different way. That’s not a workaround — it’s a parallel lane built for exactly this situation.

Here’s what I want you to take from this section, because it changes everything downstream: your taxable income and your qualifying income do not have to be the same number. Tax-return lending is one documentation path — the oldest one, and often the cheapest when it works. But it is not the only path, and choosing the right one for your file is the actual skill in self-employed lending. The rest of this page walks through every option I use to get business owners approved, and a real worked example showing how far apart those numbers can land.

The two-year rule — and the one-year exceptions

Most lenders want to see two years of self-employment history before they’ll count the income, because two filed tax years let an underwriter average your earnings and judge whether the business is stable. That’s the rule you’ll hear quoted everywhere. What you won’t hear as often: one year of self-employment can be enough under conventional guidelines when you have a prior history of W-2 work in the same field — the electrician who left a shop’s payroll to run her own crew, the IT consultant who turned his employer into his first client. Same work, new tax form. Underwriters can treat that continuity as stability.

A few more wrinkles I check on every file. First, averaging: with two filed years, underwriters generally average them — but if the most recent year declined, many lenders use the lower year alone and start asking why. A strong year followed by a soft one hurts more than two steady ones. Second, the calendar matters: your “two years” are usually measured by filed returns, so when you file — and what that return shows — effectively decides what a tax-return lender can use for the next twelve months. The year you write everything off is the year a full-doc loan gets hard. If a purchase is on your horizon, that’s a conversation to have with your CPA and your broker before filing, not after.

And third: the two-year rule belongs to tax-return lending. Several bank-statement programs I work with will consider borrowers at the 12-month mark of business history, because they’re reading your deposits, not your returns. If you’re under two years and someone told you to come back later, don’t take one bank’s seasoning rule as the market’s answer. With 50+ lenders, “later” is often “now, through a different program.”

Who counts as self-employed? The 25% rule

Lenders generally treat you as self-employed when you own 25% or more of the business that pays you. The label covers more people than most expect: sole proprietors filing a Schedule C, single-member LLC owners, S-corp and C-corp shareholders, partners with a K-1, independent contractors paid on a 1099, freelancers, realtors, truckers with their own authority, and a growing wave of gig workers whose “side income” became the income.

The 25% line produces some strange results. Pay yourself a W-2 salary from your own S-corp? You’re still self-employed in the lender’s eyes — that W-2 doesn’t get taken at face value the way an employee’s would, because you control the company that prints it. Own 20% of a firm and draw 1099 commissions? You may not be “self-employed” at all under the guidelines, and your file might be underwritten more simply. I’ve seen borrowers argue themselves into the wrong category in both directions.

Why it matters: the moment a file is flagged self-employed, the documentation rules of this page apply — business returns, cash-flow analysis, proof the business is active and viable. Knowing which side of the line you’re on, before anyone pulls credit, is step one of a clean approval.

Five ways to document self-employed income

This is the menu one bank will never show you, because most banks only sell one or two items on it. Several of these live in the Non-QM family — loans built outside the standard “qualified mortgage” box specifically for borrowers whose income is real but doesn’t photograph well on a tax return. My job is matching your file to the path that gets the strongest approval.

1. Full documentation — tax returns

One to two years of personal and business returns, analyzed line by line with the standard add-backs. When your returns support the income you need, this is usually the most affordable route, and it opens every program on the board — conventional, FHA, VA, jumbo. Don’t skip it just because you’re self-employed; skip it only when the math says to.

2. Bank-statement loans — 12 or 24 months of deposits

The workhorse of self-employed lending and the rescue path when write-offs have done their work. The lender reviews 12 or 24 months of your personal or business bank statements and calculates qualifying income from actual deposits — no tax returns required. On business accounts, an expense factor (commonly around 50%, adjustable with a CPA letter for low-overhead businesses) approximates your costs. The 12-versus-24-month choice is strategy, not paperwork: a shorter window can favor a business that’s growing fast, while the longer average rewards steady deposits. Strong fit for established businesses with healthy, consistent cash flow. Full breakdown on my bank statement loans page.

3. CPA-prepared profit & loss programs

Some lenders will qualify you on a profit-and-loss statement prepared (and in some programs, audited or reviewed) by your CPA or licensed tax preparer — sometimes alone, sometimes paired with a few months of statements. Useful when your current-year performance is much stronger than your last filed return, because a P&L can capture the business you’re running now, not the one you reported eighteen months ago.

4. Asset depletion — qualify on what you’ve saved

If you’ve sold a business, built up a brokerage account, or simply banked years of profit, asset-depletion programs convert verified assets into a qualifying income stream — no employment math at all. It also stacks: some programs combine asset-based income with bank-statement or other income on the same file. Common for retirees, recent sellers, and high-net-worth borrowers whose balance sheet is the story. Details on my asset depletion loans page.

5. DSCR — for the business owner buying rentals

Buying investment property? A DSCR loan ignores your personal income entirely and qualifies the deal on the property’s own cash flow — market rent measured against the housing payment. For self-employed investors, it means your write-offs and your rental portfolio stop fighting each other: the duplex qualifies itself.

Getting approval-ready: the paperwork, and the five traps

What you’ll gather depends on the path. For a full-documentation loan, expect two years of personal and business tax returns with all schedules and K-1s, a year-to-date profit-and-loss, and something that proves the business is real and seasoned — a business license, your CPA’s letter, or state filing records. For a bank-statement loan, it’s 12 or 24 months of statements (every page, every account you want counted), proof of business existence, and a CPA letter if we’re arguing for a lower expense factor. Every path needs the basics: ID, asset statements for the down payment, and clean explanations for anything unusual. None of it is hard. Most of it is sitting in your email already.

What actually sinks self-employed files isn’t missing paper — it’s these five, and every one of them is preventable:

• Commingled accounts. Personal spending running through the business account (or business income through personal) muddies every deposit. If a purchase is coming, separate the accounts now — clean statements for even three to six months make a visible difference.
• Large deposits with no story. An underwriter will ask about the $30,000 that appeared in March. An invoice, a contract, or a transfer record answers it in one page; “I don’t remember” stalls the file for weeks.
• Declining income with no explanation. A softer recent year isn’t automatically fatal, but it needs context — a one-time event, a deliberate slowdown, a pivot. The wrong lender averages you down or uses the low year alone; the right one listens.
• Return timing. Unfiled returns, fresh extensions, and just-amended filings each change what a lender can use. Tell your broker where you stand with the IRS before anything is submitted, not after.
• NSF fees and overdrafts on the very statements you’re handing in. Bank-statement lenders read every page. A few months of tidy account behavior before applying is worth real money in program options.

This is also where working with a person beats uploading documents into a portal. I tell you which of these applies to your file before underwriting ever sees it — while there’s still time to fix it.

Yes, self-employed borrowers can get FHA, VA, and conventional loans

Somewhere along the way, “self-employed” and “alternative lending” got welded together, and it costs borrowers real money. Let me unweld them: FHA, VA, and conventional loans are all fully available to self-employed borrowers. No agency program excludes you for owning a business. A veteran who runs a landscaping company can use his VA benefit. A first-time buyer with two solid years of Schedule C income can take an FHA or conventional loan like anyone else — including conventional financing up to the 2026 conforming loan limit of $832,750, with jumbo programs above it. The hurdle is never the loan type; it’s whether your tax returns support the income calculation. I’ve closed FHA loans for self-employed hairstylists, VA loans for veteran-owned trucking companies, and plenty of plain conventional purchases for business owners whose returns told the truth about their income.

That’s why I run self-employed files in this order: agency first, alternative second. If your returns qualify you for the house you want, an agency loan is usually the strongest deal, and we take it. When the write-offs have pushed taxable income below what you need — that’s when bank-statement and Non-QM programs earn their keep as the rescue path. Atlantis Mortgage is a full-service brokerage: purchase, refinance, FHA, VA, conventional, jumbo, reverse, and the hard files other lenders hand back. Self-employed lending is what we’re known for. It’s not all we do.

One business, three qualifying incomes: a worked example

Here’s a composite of a file I see constantly: an Oakland County S-corp owner whose business clears about $240,000 a year in real cash flow — roughly $20,000 a month in business-account deposits. Her CPA did everything right: Section 179 on new equipment, accelerated depreciation, vehicle, home office, retirement contributions, health premiums. After all of it, the return shows a $48,000 W-2 salary from her own S-corp plus $20,000 in net K-1 income — $68,000 taxable. Now watch what each documentation path does with the very same business:

Same business. Same year. Same woman. Depending purely on how the file is documented, her qualifying income lands anywhere from about $6,800 a month to $14,000 a month — roughly double. Since qualifying income drives how much home a lender can approve, the documentation decision can matter more than anything else in the file. A bank with one program never has this conversation with her. A broker has it on day one — and if her returns had qualified her for the home she wanted, full doc likely wins on cost and we’d take it. The point isn’t that bank statements always win. The point is that nobody should be declined on one version of the math when three exist.

And the menu doesn’t even end there. If her current year is running well ahead of the one she filed, a CPA-prepared P&L program can put this year’s business on the table instead of last year’s return. If she’s banked serious profit over the years — say a few hundred thousand in brokerage and retirement accounts — an asset-depletion calculation can add a second stream of qualifying income on top of what the statements show. Two businesses with identical tax returns can deserve completely different loans. That’s the entire reason this page exists: the math has versions, and you should see all of them before anyone tells you no.

Illustrative example only — not an offer of credit, a quote, or a commitment to lend. Expense factors, add-backs, and program terms vary by lender and are determined in underwriting. Your numbers will differ.

Why self-employed files belong with a broker, not one bank

Michigan runs on self-employed work. The contractor in Macomb with three crews and a Schedule C. The Oakland County builder whose income lives in draws and K-1s. Realtors, restaurant owners, manufacturers’ reps, the Ann Arbor consultant on five 1099s, the family that bought two short-term rentals up north. I’ve sat across the desk from every one of them — usually right after a bank said no — and the pattern is always the same: the borrower was fine. The fit was wrong.

A retail bank sells its own shelf. One set of programs, one rate sheet, one credit box — and self-employed guidelines that vary wildly from institution to institution. When your file doesn’t fit their box, the answer is no, and the conversation is over. The bank doesn’t tell you a lender down the street uses a friendlier expense factor, or accepts 12 months of statements where they demand 24, or treats your K-1 differently. They don’t know, and it’s not their job to know.

It is exactly my job. As a wholesale broker, Atlantis Mortgage shops your one file across 50+ lenders that compete for it — agency lenders, jumbo investors, and the Non-QM specialists who build bank-statement, P&L, asset-depletion, and DSCR programs for a living. Each one has different seasoning rules, expense factors, credit floors, and appetites. Self-employed lending is a matching problem, and the broker model exists because nobody wins a matching problem with a catalog of one.

And here’s the part I take personally: I read your file before it goes anywhere, and I place it with the lender whose guidelines it already fits. That’s the difference between applying and hoping — and applying because your broker already knows the answer. Bank said no? That’s where I start.

Self-employed mortgage questions, answered straight

How many years do you have to be self-employed to get a mortgage in Michigan?

Two years of self-employment history is the standard most lenders look for, documented with tax returns or bank statements. One year can be enough if you have previous W-2 experience in the same field or industry — for example, an electrician who left a company payroll to run her own shop. Atlantis Mortgage works with 50+ wholesale lenders whose seasoning requirements vary, so a file one bank declines for history can still be approved elsewhere.

How do I prove my income if I’m self-employed?

You have more than one path. Full documentation uses one to two years of personal and business tax returns. Bank-statement programs use 12 or 24 months of deposits instead of returns. Some programs accept a CPA-prepared profit-and-loss statement, asset depletion converts savings and investments into qualifying income, and DSCR loans qualify rental purchases on the property’s own cash flow. The right path depends on how your business pays you and what your returns show.

Can I get a mortgage with only one year of self-employment?

Often, yes. Conventional guidelines allow one year of self-employment when you have a prior history of working in the same line of work, and several Non-QM bank-statement programs will consider 12 months of business history. The deciding factors are usually the stability of your industry, your credit profile, and your down payment. If you are under the two-year mark, have a broker review your file before you assume you have to wait.

Do tax write-offs hurt my mortgage approval?

On a traditional, tax-return-based loan, yes — most underwriters start from your net taxable income, so every dollar you deduct is a dollar you cannot qualify with, although certain paper deductions like depreciation can be added back. On a bank-statement or other Non-QM program, write-offs largely stop mattering because qualifying income is calculated from your actual deposits instead of your tax returns.

What counts as self-employed to a mortgage lender?

Lenders generally treat you as self-employed when you own 25% or more of the business that pays you. That includes sole proprietors, single-member LLCs, S-corp and C-corp owners, partners, independent contractors paid on a 1099, freelancers, and many gig workers. If you own less than 25% but earn commission or 1099 income, you may be underwritten differently — sometimes more favorably.

Can self-employed borrowers get FHA, VA, or conventional loans?

Yes. FHA, VA, and conventional loans are all available to self-employed borrowers who can document qualifying income on their tax returns — the program itself does not penalize you for owning a business. The challenge is usually the income calculation, not the loan type. When tax returns support the numbers, an agency loan is often the most affordable route; when they do not, bank-statement and other Non-QM programs fill the gap.
