If You're Paid Under CIS, Do Lenders See You as Self-Employed?

See which of two routes a lender puts your CIS income down, and why the figure changes depending on the answer.
Quick Answer
For tax purposes, yes. For mortgage purposes, not always. A subset of lenders assess CIS income from your gross payment and deduction statements through their employed income route, on as little as three months of history and no accounts at all. Others apply full self-employed treatment based on net profit.
That is not a small distinction. Gross receipts and net profit are separated by the whole of your business expenses, and for a trade running a van, tools and materials that is rarely a modest figure.
So the question that decides your borrowing is not what HMRC calls you. It is which of the two published routes the lender you approach happens to operate, and whether your paperwork fits the one that suits you.

The deduction you resent is the reason a lender can move quickly
Every month a slice of your money disappears before it reaches you. Twenty percent if you are registered, thirty if you are not. It arrives as a subtraction on a piece of paper you did not ask for.
That piece of paper is the most useful mortgage document most subcontractors own, and almost nobody tells them so.
Because the deduction exists, HMRC obliges your contractor to issue you a payment and deduction statement within fourteen days of the end of each tax month, and that statement has to show the gross figure before anything was taken off. A third party, on a legal deadline, certifying what you earned.
An ordinary sole trader has nothing equivalent. They have invoices they wrote themselves, which is the definition of self certification, and a tax return that arrives once a year and looks backwards. You have a monthly, externally produced record. For a broader view of how non standard cases are placed, start with our specialist mortgages hub.
The regulator will not let a lender take your own word for your income, which is why that distinction has teeth. Evidence has to come from a source independent of you. Your contractor is exactly such a source, and the law already makes them produce the document.
Most subcontractors have never thought of the statement as anything but a record of money taken off them. Read the other way round, it is a monthly certificate of what you earned, issued by somebody with no reason to flatter you, on a deadline set by law.
Why "am I self-employed?" is the wrong question to be asking
Readers arrive at this subject wanting a ruling on their status. It is the natural question and it is a dead end, for two reasons.
The first is that employment status is legally sensitive, fact specific and not something a mortgage broker should be adjudicating. Whether any individual is correctly treated as a subcontractor rather than an employee is a matter between them, their contractor, their accountant and HMRC. We are not going to answer it here and you should be wary of anyone who does.
The second is that lenders are not answering it either. They are not classifying you. They are classifying your paperwork.
An underwriter is not sitting in judgement on whether you should really be on PAYE. They are looking at what evidence exists, who produced it, and whether their own criteria have a box it fits into.
Reframed that way, the question becomes tractable. It is not "what am I?" but "what can I put in front of an underwriter, and which lenders have a published route that reads it?"
That shift matters practically, not just philosophically. If the problem were your status, there would be nothing to do about it. Because the problem is documentary, there is quite a lot to do about it, and most of it is free.
The same worker, two different incomes, depending on who is asked
Published criteria fall into two behaviour groups, plus a revealing hybrid.
The first group assess the gross figure from your CIS statements or payslips, annualised, with short history and no accounts. One of the largest lenders in the country places its CIS input fields inside a document titled as a guide to keying employed income, and asks for the gross income from the latest three payslips with three months of matching bank statements. One building society annualises the latest thirteen weeks. Another works from a daily rate and states plainly that it needs no accounts or tax returns at all.
The second group do not treat CIS as a special case. You are a sole trader, the ordinary self employed calculation applies, and net profit from your tax calculation is the figure. One lender's criteria say precisely that in terms.
Most lenders sit in neither group, because their published criteria never mention CIS. That is not refusal. It means no special route exists, so the general self employed rules apply by default.
That distinction is worth holding onto, because it is routinely reported as hostility. Several large lenders were checked for this article and no CIS entry was found in their published criteria at all. Silence means unhandled, not unwelcome. It does mean the default is the slower, evidence heavier path. Our self-employed mortgages guide describes that default in full.
What the lender publishes | What your income figure becomes |
CIS assessed on gross statements | Annualised gross, often on months rather than years |
CIS treated as self-employed | Net profit from your tax calculation |
Both routes published | Whichever the lender selects for your file |
No mention of CIS at all | The general self-employed policy, usually two years |
The hybrid is the most instructive of all. One society publishes three acceptable evidence sets and two calculation methods for the same applicant, a twelve month gross average with materials stripped out, or the annual net profit figure. The same person, at the same lender, has two possible incomes.
Two lenders, opposite instructions, on the identical document
If you want proof that this is about paperwork rather than principle, here it is.
One major lender, assessing weekly paid CIS workers, asks for the latest twelve payslips. Another lender's published criteria state that twelve months of weekly remittance slips will not be accepted as evidence of income.
That is the same document, produced the same way, refused by one and required by the other. Nothing about the applicant has changed between those two sentences.
It also explains a pattern subcontractors find baffling: being declined somewhere, walking into somewhere else with the identical folder, and being fine. The folder was never the problem. The match between the folder and the lender's published route was.
It has a practical consequence too. If your contractor pays weekly and issues weekly slips, that is not a neutral fact about your admin. It narrows the list of lenders whose published route your paperwork actually fits, before anything else is considered.
The assumed working year nobody mentions
Lenders on the gross route do not simply multiply your rate by fifty two weeks. They apply an assumed working year, and they publish it.
One building society uses a daily rate times five times forty six weeks. Another uses forty eight. A fifty two week assumption is claimed for other lenders but was not verified at source in this research, so treat it as unconfirmed.
Take a two hundred and fifty pound day rate as an illustration. Over forty six weeks that annualises to fifty seven thousand five hundred pounds. Over forty eight, sixty thousand. Over fifty two, sixty five thousand. A seven and a half thousand pound spread, around thirteen percent, on identical work, created entirely by an assumption about how many weeks a year you work.
At a typical income multiple that is tens of thousands of pounds of borrowing capacity, decided before anyone looks at your credit file. Figures are illustrative and multipliers vary by lender and change without notice.
None of this is published to be unfair. A lender annualising a day rate has to assume something about holidays, weather and gaps between jobs, and forty six weeks is a defensible guess for outdoor trades. The point is simply that the guess is theirs, it varies, and it moves your number more than most applicants realise.
Where the real gap sits, and it is not the deduction
Three separate subtractions sit between your gross figure and your net profit, and conflating them is the commonest error in everything written about this subject.
The CIS deduction itself is not the gap. It is an advance payment of tax, and lenders assess affordability on income before income tax for every applicant regardless of how they are paid. A lender using your gross figure is not ignoring tax. It is doing exactly what it does for an employed applicant.
Your allowable business expenses are the gap. Net profit is receipts minus expenses, and nothing about the CIS deduction touches that calculation. Materials can be subtracted twice over, in the sense that one lender strips them out even on the gross route.
CIS is a tax scheme and we are not tax advisers. How your expenses are claimed is a matter for you and your accountant, governed by tax rules, not by what would suit a mortgage application. If you take one thing from this section, let it be that the two routes measure different quantities, and that the choice of route is the lender's, not yours. Our guide to using net profit covers the second measure in detail.
Thirteen weeks or two years: how much history you actually need
The short history route is real, published, and not confined to obscure specialists.
Three months of payslips with matching bank statements appears in one major lender's keying guidance. Thirteen weeks of income appears in one society's CIS criteria, alongside a requirement for a minimum of one year of work experience in a similar industry. Another requires six months of payslips, twelve months in the industry, three months with the same employer and no more than three employers in the preceding year.
Notice what those conditions have in common. They are not asking for a longer paper trail. They are asking for evidence of continuity in the trade, which is a different test and a much easier one to satisfy if you have been on the tools for years.
This is the part most subcontractors get wrong when they self assess their chances. Time in the industry and time with a current set of accounts are two separate clocks, and the short history lenders care far more about the first than the second.
Against that, lenders with no CIS route will apply their general policy, which commonly means two years of accounts or two years of tax calculations with overviews.
That is the position most subcontractors are quoted, because it is the position that applies at the lenders most people walk into first. It is accurate advice about those lenders and a poor description of the market as a whole. If you also move between contracts with breaks in between, our guide on gaps between contracts covers that separate question, and if you are paid through an umbrella rather than under CIS then umbrella contractor mortgages is the relevant guide instead.
Red flags that end a CIS application
Some of these are fixable in an afternoon. Others need a different lender.
Payments that cannot be traced. One major lender's guidance is explicit that income which cannot be verified on both the payslip and the corresponding bank statement is dropped from affordability altogether. Cash top ups, payments into a partner's account and irregular lump sums all fail that test quietly.
Gross payment status, oddly, can complicate the gross route. If you hold it, no deduction is made, so the monthly payment and deduction statement that the short history lenders want may not exist in the same form. No lender criteria found in this research address that directly, so treat it as a question to raise before applying rather than a settled rule.
The thirty percent rate, which applies where a subcontractor is not registered, is visible on every statement. Whether an underwriter reads anything into it was not established in this research, and we would not assert that it does. Whether and how to register is a question for an accountant or HMRC, not for us.
Finally, a gap between what your statements show and what your tax return shows. Both documents will be in the file, and an underwriter will notice.
That last one is worth a sentence of reassurance. Gross statements and a net profit return are supposed to differ, because one is before expenses and the other after. What causes trouble is a difference nobody can account for, not a difference that has an obvious cause.
A groundworker, three months of statements, and two very different answers
Consider an illustrative composite. A groundworker on a two hundred and forty pound day rate, eleven years in the trade, registered under CIS, with fourteen months since he last had accounts prepared and a deposit of forty two thousand pounds towards a two hundred and eighty thousand pound house.
His first approach was to a lender with no published CIS route. General self employed policy applied, two years of tax calculations were requested, and the most recent net profit figure after a heavy year for tools and van costs supported far less than he expected.
Presented instead to a lender operating the gross route, with three months of payment and deduction statements, matching bank statements showing every payment landing in his own account, and evidence of continuous work in the trade, the case was assessed on annualised gross income and proceeded. Same man, same year, same folder, different published route. Those figures are illustrative, and criteria differ from one lender to the next.
FAQs
Are CIS subcontractors self-employed for mortgage purposes?
For tax you are self-employed, but lenders vary. Some assess CIS income through their employed income route using gross payment and deduction statements, while others apply full self-employed treatment on net profit. The classification that matters is the one the lender applies to your paperwork, not the one HMRC applies to your tax.
Can I get a mortgage with only three months of CIS statements?
It is published as acceptable by at least one major lender and one building society, usually alongside a requirement to show a longer record of working in the trade. It is not universal, and lenders without a CIS route will generally want two years of accounts or tax calculations instead.
Will I be assessed on my gross income or my net profit?
That depends entirely on the lender. Gross route lenders annualise the figure on your statements, sometimes after stripping out materials. Net profit lenders use the figure from your tax calculation, which is after all your business expenses. The two can be a long way apart.
Does the 20% deduction reduce how much I can borrow?
Not directly. The deduction is an advance payment of tax, and affordability is assessed on income before income tax for every applicant. What reduces the assessed figure on the net profit route is your business expenses, which is a separate thing entirely.
Does holding gross payment status help or hurt?
It helps cash flow, but it may remove the monthly payment and deduction statement that short history lenders rely on. No published criteria found in this research address the point, so it is worth confirming a lender's position before applying rather than assuming. Whether to apply for it is a question for your accountant.
Why was I declined by one lender and accepted by another with the same documents?
Almost certainly because the two operate different published routes. One lender requires twelve weekly payslips for a weekly paid subcontractor while another states that weekly remittance slips will not be accepted at all. The folder did not change. The route did.
Summary
Being paid under the Construction Industry Scheme does not put you in a single mortgage category. Some lenders read your gross statements as though you were employed and can work from a few months of paperwork. Others treat you as any other sole trader and want net profit over two years. The difference between those two figures is the whole of your business expenses, so the route decides the outcome. If you have been told you need two years of accounts, it is worth checking whether that was the lender's rule or just the first lender's rule.
