What underwriting counts as your income when you work for yourself

If you are a contractor, a consultant working corp-to-corp, or anyone whose income arrives without a payslip, you have probably had a version of this conversation. You know what you earn. The lender looked at the same return and produced a smaller number, and nobody explained the gap.

The gap is not an error, and it is usually not a judgement about you. Two things are happening. There is a definition that decides whether any of this applies to you at all, and it turns on ownership rather than on payslips. And then there are three different numbers on your tax return, each with a claim to being "your income", none of which underwriting uses unmodified.

First, what makes you "self-employed" at all

Not the absence of a payslip. The usual definition across the agency rulebooks is an ownership interest of 25% or more in a business.

That one line decides more than people expect, and it cuts the opposite way from what most expect:

• Own a quarter or more of a company and you are self-employed for underwriting even if that company pays you a W-2 every fortnight.
• Own less than that, with a W-2, and you are generally treated as an ordinary employee — the business return stays out of it.

So the question is not "do I get a payslip". It is "how much of the thing paying me do I own".

The three numbers, and why none of them is the answer

Gross receipts is what the business took in. Nobody lends against it.

Net profit — the bottom line you pay tax on — is closer, and it is the number most people assume is used. It is also the number your accountant spent the year making as small as legally possible, which is the right job for them to be doing and the wrong number to be judged on.

Qualifying income is what underwriting actually calculates: the net profit, with specific deductions added back, averaged across the period being looked at, and adjusted if the trend is downward.

The whole of this guide is the distance between the second and the third.

How long you need, and which years count

Two separate questions that the same reader always asks together.

How long. Two years of self-employment is the figure everyone quotes, and it is the default. It is not the only case the rulebook contemplates: the guidelines allow for a shorter history where the income is documented, the business is established enough to be assessed, and there is prior experience in the same line of work. Somebody who spent six years as a salaried engineer and now contracts in the same field through their own company is a different file from somebody who started something new last spring, and the rulebook knows it.

Which years. Usually the last two, averaged — which is why a strong year next to a weak one produces a number that satisfies nobody.

The direction matters as much as the figures. Income that is rising is generally averaged across both years, so a good year is diluted by the one before it. Income that is falling is treated more conservatively, often on the most recent year alone rather than the average, because the question has stopped being "what do they earn" and become "what will they earn next year".

If your US credit file is also short, building credit from zero is the companion to this one.

What gets added back

Some deductions reduce taxable income without any money leaving your account. Those are the ones underwriting restores, because the cash is still there to make a mortgage payment with.

Depreciation. The largest one for most people. You bought equipment, a vehicle, a computer; the tax code lets you deduct its value over time, or immediately. No cash left your account this year, so it comes back.

Depletion and amortisation. The same principle for intangible and resource assets. Rarer, same treatment.

Business use of home. Added back for two reasons: no separate cash left your account for it, and the cost of the house is already counted against you in the housing ratio. Leaving it deducted would charge you for the same roof twice.

The depreciation portion of the standard mileage deduction. This is the one people are most surprised by. If you claim the standard mileage rate rather than actual expenses, a published portion of that rate is depreciation — the IRS states the figure each year. That portion is not a cash expense, and it is added back. For somebody driving a lot of business miles, it is not a small adjustment.

Genuinely non-recurring losses. A one-off event, documented as such, can be excluded. The emphasis is on documented and on one-off: a loss that happens every other year is not non-recurring.

The cash-flow worksheets lenders use for this are standardised — the agencies publish them, and most lenders work from one version or another. That matters because it means the method is not a matter of opinion. Somebody either walked your return line by line or they did not.

The shape of your business changes the paperwork

Sole proprietor, Schedule C. The simplest case. Income is the net profit from the schedule, plus the add-backs above.

S-corporation owner paying yourself a W-2. The case people most often get wrong, and the one worth reading twice. Because you own more than a quarter of it, the W-2 is not treated as ordinary employment income from an unrelated employer. You are self-employed, the business return comes into the file, and the wages and the K-1 are read together as one picture rather than as a safe half and a risky half.

Partnership or S-corporation, K-1. Your share arrives on a K-1 and the business returns come in alongside your personal ones. What underwriting is looking for is not only that the income exists but that it can reach you — either because it has actually been distributed, or because the business holds enough liquidity that taking it would not damage the business. Profit on paper that has never left the company is the most common reason a K-1 figure does not fully count.

Corp-to-corp. The most common shape in this corridor, and the one with the least written about it.

C2C usually means one of two things. Either you are a 1099 contractor, which is a Schedule C file and reads like a sole proprietorship. Or you have your own S-corp or LLC that holds the contract and pays you, which is the case above — the entity's return is part of your file, and your ownership of it makes you self-employed regardless of how you pay yourself.

If you are also on a visa, these two questions arrive together and are usually assessed together — what the guidelines say about work authorisation covers the other half, and E-1 and E-2 files are very often self-employment files wearing a visa label.

Two things underwriting tends to ask about that catch people out. A contract that renews annually is normal in this line of work, but it is read as evidence about continuity, so the renewal history matters more than the current term. And a single end client for several years is a strength on the income side and a question on the concentration side — worth addressing in the file rather than leaving to be noticed.

The money in the business account

The question almost every contractor asks, and the one the guides are usually quiet about: can the deposit come out of the business?

Generally yes, where you own the business, and with a condition attached. The lender has to satisfy itself that taking the money out will not damage the business — which in practice means showing the business can keep operating without it. A letter from your accountant, or a cash-flow analysis on the business, is the usual way that gets evidenced.

Two practical consequences. Moving the money to your personal account well before you apply does not avoid the question, because the source still gets traced. And the amount matters relative to what the business turns over: a withdrawal that is routine for your business is a different conversation from one that empties it.

The thing that actually sinks files

Not write-offs. A decline.

If this year is materially lower than last, that is a question before it is a number — and the answer "I took time off" or "a client left" needs to be in the file, in writing, with evidence of what happened since. A downward trend without an explanation tends to be treated conservatively, which usually means the lower year rather than the average.

The practical consequence is about timing rather than argument. Filing a weak year and then applying is a harder conversation than applying first. Not advice to delay a filing — advice to know which order you are doing things in, and to talk to somebody before rather than after.

When the returns genuinely do not work

Sometimes the add-backs are not enough, and the return reflects a year that was simply thin. There are programmes built for this.

Bank-statement programmes. Rather than the return, these use business deposits over twelve or twenty-four months, with an expense factor applied to approximate what the business actually costs to run. They are non-QM products, so the terms differ from a conventional loan — typically a larger deposit and a higher rate. That is the trade, and it is worth pricing properly rather than assuming either that it is unavailable or that it is free.

Asset-based approaches. Where there are substantial liquid assets, some programmes qualify against those rather than against income.

Neither is a workaround. They are different products with their own rules, and they exist because the standard calculation does not fit every real business.

Where the difference between lenders shows up

Worth separating first, because this guide quotes some figures and hedges others, and the difference is not arbitrary.

The fixed ones. The 25% ownership definition and the two-year default are agency rules — written down, applying across lenders, safe to quote because they are not anybody's policy preference.

The ones I hedge. What a particular lender will do with a nineteen-month business, a declining year, or a K-1 from a company you part-own. That is credit policy. It differs between lenders, it changes, and a figure written on this page would go stale and be quoted back at me. Where this guide says "generally" or "often", that is why.

That second category is also where a broker is worth something, and the reason is structural rather than a slogan about choice. A bank funding its own loans applies its own credit policy on top of the agency rulebook — overlays, in the trade. Two years rather than one. A reluctance to look at anything other than a standard return. None of it is visible to you, because what reaches you is a yes or a no.

Working through a panel of wholesale lenders means the same file is measured against several rulebooks rather than one. On a straightforward salaried file that rarely matters. On a self-employed file with add-backs, a K-1 and a year that needs explaining, it is often the difference between an answer and a different answer.

What to do with this

Bring two years of personal and business returns, the K-1s if there are any, and a year-to-date profit and loss. The full document list covers what else comes with them. If there is a weak year or a decline, bring the explanation too — the file is better with it than with an underwriter guessing.

And have the conversation before you file, if the timing is still open. Of everything on this page, the order you do things in is the part most within your control and the part most often decided by accident.

This describes how self-employment income is generally assessed. It is not tax advice, and your accountant is the right person to ask about what to deduct. The question here is only how the return you filed is read afterwards.
