The short answer: where the maths actually tips
A limited company is the right call for most growing domiciliary care agencies, but rarely for the tax saving alone. On the 2026/27 numbers, if you draw every penny of profit out of the business, a sole trader and a limited company end up within a few hundred pounds of each other across the profit levels a typical home care owner sits at. The deciding factors are limited liability, the ability to retain profit cheaply, and who legally holds your Care Quality Commission (CQC) registration.
Start with what each structure means. A sole trader is you, personally, trading as the business: you pay Income Tax and Class 4 National Insurance on the whole profit whether you spend it or not, and you are personally liable for everything the business does. A limited company is a separate legal person: it pays Corporation Tax on its profit, you take money out as a small salary plus dividends, and your liability is generally limited to what you put in. For a regulated activity like domiciliary care, that separation is not a technicality. It changes who carries the risk when a safeguarding claim or an employment dispute lands.
This is a sector where the right answer is rarely generic. If you want the wider context for home care finances, our healthcare and social care accountants page sets out how we work with CQC-registered providers, and the guide on what an accountant costs for a domiciliary care provider covers the fee side. This article is about the structure decision underneath it.
The 2026/27 numbers at three profit levels
At a full profit draw, the limited company saving in 2026/27 is small and it is not even consistent: the sole trader wins at lower and higher profit, and the company only nudges ahead in a middle band. Here is the same owner profit run through both structures, taking a £12,570 director salary plus dividends in the company case, with the Employment Allowance covering the employer National Insurance on that salary.
Take a domiciliary owner whose business clears £40,000 of profit after paying carers and overheads. As a sole trader, Income Tax and Class 4 National Insurance come to about £7,132, leaving £32,868. Through a company, Corporation Tax at 19 percent plus dividend tax at the new 10.75 percent rate leaves roughly £32,454. The sole trader is about £415 better off.
Move the same owner to £60,000 of profit. The sole trader keeps about £46,111. The company, having sheltered more of the profit inside the basic-rate dividend band before the owner crosses £50,270 of personal income, keeps about £46,733. Now the company is ahead, but only by around £620.
Push it to £80,000 and the picture flips back. The sole trader keeps about £57,711. The company, now paying Corporation Tax at the 26.5 percent marginal rate on profit above £50,000 and dividend tax at 35.75 percent on the higher slice, keeps about £56,300. The sole trader is roughly £1,400 ahead again.
Why the old "incorporate above £50k" rule no longer holds
The rule of thumb that you should incorporate once profit passes £50,000 was built on dividend rates that no longer exist. From 6 April 2026 the dividend ordinary rate rose to 10.75 percent and the upper rate to 35.75 percent, both 2 percentage points higher than before, confirmed in the Autumn 2025 Budget. That single change quietly removed most of the extraction advantage a company used to enjoy.
Work it through on a single pound of profit. As a sole trader in the basic-rate band you pay 20 percent Income Tax plus 6 percent Class 4 National Insurance, so 26 percent. Through a company, that pound suffers 19 percent Corporation Tax, leaving 81 pence, then 10.75 percent dividend tax on what is paid out, which is another 8.7 pence. Total: 27.7 percent. The company is now slightly worse on a basic-rate pound, where it used to be clearly better.
The higher-rate band tells the same story more sharply. A sole trader pays 40 percent plus 2 percent, so 42 percent. A company paying Corporation Tax at the 26.5 percent marginal rate and then the 35.75 percent dividend upper rate on the remainder loses close to 53 percent of that pound once it is fully extracted. On a full draw, in other words, the maths has flipped against the company at the very profit levels where it used to win. You can confirm the dividend figures on HMRC's guidance on tax on dividends.
This is also why a one-size answer is dangerous. The general version of this comparison, set out in our sole trader vs limited company at £50k analysis, reaches the same conclusion for trades across the board. For domiciliary care the stakes are higher because the non-tax reasons to incorporate are stronger than in most sectors.
When a limited company still wins for a care agency
A limited company wins for a domiciliary care agency whenever you are building something rather than running a one-person round. The decision turns on two questions: how much profit you reinvest, and how much risk you are willing to carry personally. Plot a home care business on those two axes and the answer becomes obvious.
The first big win is retained profit. Local authority care contracts routinely pay 30 to 60 days in arrears, while your carers are paid weekly or fortnightly. That gap has to be funded from somewhere. A company can hold back profit taxed at only 19 to 26.5 percent Corporation Tax and use it as working capital, rather than a sole trader drawing the same money and losing up to 42 percent of it to Income Tax and National Insurance first. If you are reinvesting in recruitment, training, or a second contract, the company keeps far more of each pound working in the business.
The second is limited liability. Domiciliary care is a regulated activity with real exposure: safeguarding allegations, employment claims from carers, a disputed CQC finding. A sole trader meets all of that with personal assets. A company ring-fences the business, which is why most providers serious about scale incorporate well before the tax case alone justifies it.
The third is pension and income flexibility. A company can make employer pension contributions for the owner that are Corporation Tax deductible and carry no National Insurance, a far more efficient route than a sole trader contributing from already-taxed profit. Shares can also be split with a spouse who genuinely works in the business, spreading dividends across two sets of allowances and bands. Neither option exists for a sole trader.
What actually changes when you incorporate a care agency
Incorporating a domiciliary care business is more than a tax form: it triggers a fresh CQC registration and a payroll handover that have to be sequenced carefully. The Care Quality Commission treats the limited company as a new legal entity, so you cannot simply move your existing registration across.
The CQC point catches owners out every time. Because the company is a different registered person from you as an individual, you must apply to the Care Quality Commission as a new provider, with the company as the registered provider and a named registered manager. You cannot deliver regulated care under the company until that registration is granted, and the application takes time. The practical rule is simple: never deregister the old entity until the new company registration is live, so there is no gap in cover.
Payroll is the second moving part. Your carers transfer to the company as the new employer, which usually means their employment moves across under TUPE (Transfer of Undertakings, Protection of Employment), preserving their continuous service and terms. The company runs PAYE, applies the £12.71 National Living Wage from April 2026, and must pay for travel time between calls as part of meeting the minimum wage, a point HMRC actively checks in this sector. On the upside, the company claims the Employment Allowance, £10,500 for 2026/27 with the old £100,000 cap now removed, against its employer National Insurance. Our payroll and PAYE service handles that transfer so no carer drops off mid-cycle.
There is one more quiet win for sole traders earning above £50,000. From April 2026, Making Tax Digital for Income Tax (MTD ITSA) requires sole traders and landlords over that gross-income threshold to keep digital records and file quarterly. A limited company is outside MTD ITSA entirely, because it files a Corporation Tax return instead. For a domiciliary owner whose turnover comfortably clears £50,000, incorporating removes five filings a year and replaces them with one company return.
Here is how the three common ways to handle this decision actually compare for a domiciliary care provider:
| What you need | DIY / software | Generic accountant | LOYALS specialist |
|---|---|---|---|
| Models the maths with carer payroll and travel-time minimum wage built in | ✗ Generic figures only | ● If you ask | ✓ Standard |
| Flags that incorporating means a fresh CQC registration, not a transfer | ✗ | ✗ | ✓ Sequenced for you |
| Tests whether your carers are genuinely self-employed or employed | ✗ | ● | ✓ Status reviewed |
| Builds local authority payment delays into the retain vs draw decision | ✗ | ✗ | ✓ Cashflow modelled |
| Open Mon to Sat for urgent year-end and registration calls | ✗ | ✗ Mon to Fri 9 to 5 | ✓ 10am to 7pm Mon to Sat |
| Fixed monthly fee, no surprise invoices | ✓ | ● Hourly billing common | ✓ Fixed monthly |
This is why most domiciliary providers weighing up incorporation move from a generalist to a care specialist before they make the call.
How to decide: DIY, a generalist, or a specialist
Decide on the things the tax maths cannot see: your liability exposure, your reinvestment plans, and your CQC position. The arithmetic above shows the structure barely moves your take-home on a full draw, so let it be a tiebreaker, not the headline.
If you are a single carer running a small private round, drawing everything you earn, and not planning to grow, staying a sole trader is usually right. It is cheaper to run, simpler to file, and on the 2026/27 numbers the tax is fractionally lower. You can always incorporate later when the situation changes.
If you employ carers, hold or want a CQC registration, take local authority contracts, or intend to grow, the limited company is almost always the better home even though the headline tax saving is small. You get limited liability over a workforce, a cheaper way to retain working capital against slow-paying contracts, and the pension and share-splitting options that genuinely move the numbers. The point is to model your real position, including the carer wage bill and the contract payment timing, rather than a textbook profit figure. Our limited company formation service and tax planning advisory exist to do exactly that modelling before you commit.
