Self-Employed Carers vs Employed Carers: The Status Risk Every Domiciliary Care Agency Should Check

The short answer: are your carers actually self-employed?

For most domiciliary care work, no. The carer is an employee for tax even if everyone involved would prefer otherwise. HMRC sets out its position in its Employment Status Manual at ESM4015, the guidance on careworkers, and the thrust of it is simple: a carer who attends at times you set, follows your care plan, and works under your direction looks like an employee, because that is what an employee is.

Two different things get muddled here, so let me separate them at the start. Employment status for tax is the question of whether an individual you engage directly is employed or self-employed. IR35, properly called the off-payroll working rules, is a separate question that only arises when a carer supplies their services through their own limited company. The vast majority of agency exposure sits in the first category, not the second. We come back to IR35 near the end, because it catches far fewer agencies than people fear.

Why does this land on the agency rather than the carer? Because if status is wrong, HMRC pursues the business that should have operated the payroll, not the individual who was happy to invoice. You become the unpaid tax collector, and the bill is yours. That is the part owner-managers tend to discover at the worst possible moment, usually when a carer makes a holiday pay claim or an HMRC compliance check lands. If you want the wider picture on how a specialist supports this sector, our healthcare and social care accountants page sets out where this fits, and the day-to-day mechanics live with our payroll and PAYE service.

Self-employed vs employed: what changes for your agency

Everything that costs money changes. When a carer is genuinely self-employed they invoice you, sort their own tax through Self Assessment, and carry their own risk. You pay the invoice and nothing else. The moment that carer is an employee, a stack of employer duties switches on, and none of them are optional.

Here is what an employed carer brings that a self-employed one does not. You operate PAYE (Pay As You Earn) and deduct Income Tax and employee National Insurance from their wages in real time. You pay employer National Insurance at 15 percent on earnings above the £5,000 secondary threshold for 2026/27. You provide paid holiday, which for irregular-hours carers accrues at 12.07 percent of hours worked. You auto-enrol eligible carers into a pension and contribute a minimum 3 percent. You handle Statutory Sick Pay, statutory maternity and paternity pay, and you carry the cost of any sleep-in cover and travel time that counts toward the National Living Wage, now £12.71 an hour from April 2026.

None of that exists on the self-employed side, which is exactly why the self-employed label is tempting and exactly why HMRC scrutinises it. The saving is real, so the incentive to misclassify is real, so the compliance attention follows. A genuinely self-employed live-in carer who runs their own business, sets their own terms and works for several clients can exist. A rota of carers you control, dispatch and supervise almost certainly cannot.

One practical point owner-managers miss: getting status right is not only a cost. An employed carer is a more stable carer, with holiday, sick pay and a pension, which in a sector defined by turnover is worth something real. The agencies that treat compliant employment as a retention tool, not just a tax cost, tend to keep staff longer.

The three tests HMRC uses to decide status

HMRC looks at how the work really happens, not what the paperwork says, and three tests do most of the heavy lifting. Get a feel for these and you can usually predict the answer before you open the CEST tool.

Control is the big one for care. If you decide when the carer works, which client they see, what tasks they do and how they do them, that points hard at employment. A self-employed contractor controls their own method and schedule. A carer slotted into your rota and following your care plan does not. In the leading case of Chatfield-Roberts, a live-in carer engaged through an agency was found to be an employee precisely because of this kind of control.

Personal service and substitution is the second. A genuinely self-employed person can usually send a competent substitute to do the job. Care rarely works that way: clients need a known, trusted, often DBS-checked individual, and the agency would never let a carer send a random replacement. No real right of substitution points firmly to employment.

Mutuality of obligation is the third. If you are obliged to offer work and the carer is obliged to accept it, that ongoing give-and-take is the fabric of an employment relationship. Even zero-hours carers often have enough of a pattern that mutuality is present in practice.

These tests sit alongside the staffing and fit-and-proper expectations that the Care Quality Commission (CQC) already places on registered providers, which is why a carer you can direct and rely on for safe care looks even less like an independent contractor. The flowchart below walks the logic in the order HMRC tends to apply it.

The agency rules: why self-employed often still means PAYE

Even when a carer looks borderline self-employed, a second piece of law usually closes the gap: the agency rules. These sit in section 44 of the Income Tax (Earnings and Pensions) Act 2003, and they exist precisely to stop labour being dressed up as self-employment to dodge PAYE.

The test is narrow and brutal. Where a worker personally provides services and is subject to (or to the right of) supervision, direction or control as to the manner in which they do the work, the agency must treat the payments as employment income and operate PAYE. That phrase, supervision, direction or control, is usually shortened to SDC. For domiciliary care the SDC test is almost always met, because supervising the manner of care is the whole point of a regulated agency.

So an agency can find that a carer fails to be a clear employee under the general tests, yet is still pulled into PAYE by the agency rules. The two routes stack. This is why "but they wanted to be self-employed" and "but the introductory agency said it was fine" are not defences. HMRC does not care what was preferred. It cares what the law requires, and for a managed care agency the answer is almost always payroll. For more on tightening up the carer agreements themselves, our piece on the HMRC reclassification trap for chair-rent and employed status walks through the same status logic in a different sector.

What a wrong status call actually costs

It costs far more than the tax you skipped, because HMRC rebuilds the whole employment relationship as if you had run it correctly all along. The headline saving on the self-employed model is the employer on-cost you avoided. The headline risk is that exact on-cost coming back with interest and penalties on top.

Take one carer earning around £22,000 a year. Reclassified as an employee, the employer-side cost you should have been paying breaks down roughly as follows: employer National Insurance of about £2,550 (15 percent on pay above the £5,000 threshold), holiday pay of about £2,650 (12.07 percent), and a minimum pension contribution of about £470 (3 percent on qualifying earnings). That is roughly £5,670 a year, per carer, before HMRC adds the Income Tax and employee National Insurance you failed to deduct, before interest, and before penalties.

Now stretch that across time and headcount. HMRC can normally reach back four years for careless behaviour, six years for National Insurance, and up to twenty years where it argues the underpayment was deliberate. A single carer carried on the wrong status for four years can therefore reach £6,000 to £15,000 of exposure once everything is added. Multiply that by ten carers and you are looking at a number that can sink a small agency. This is the silent liability the welfare-exemption and margin conversations never surface, and it is why a specialist looks at it first. The waterfall below shows just the employer-side annual build-up for one carer.

Where IR35 fits: carers with their own limited company

IR35 only enters the picture when a carer works through their own limited company, and that is much rarer than the headlines suggest. The off-payroll working rules, to give IR35 its proper name, ask whether a worker who supplies services through their own company (a personal service company, or PSC) would have been an employee if you had engaged them directly. If yes, the income is taxed broadly like employment income.

The detail that matters for care agencies changed on 6 April 2026. HMRC raised the thresholds that define a "small" company, so the turnover ceiling rose from £10.2 million to £15 million and the balance sheet ceiling from £5.1 million to £7.5 million. Around 14,000 businesses moved from medium to small as a result. The practical effect for most domiciliary care agencies is this: you are almost certainly "small", which means the responsibility for the IR35 decision sits with the carer's own company, not with you, and the agency does not have to issue a Status Determination Statement.

That is genuinely useful to know, but do not let it lull you. The overwhelming majority of carers are engaged as individuals, not through companies, so IR35 simply does not apply to them. Their risk is plain employment status, which the agency rules and the general tests govern, and which sits squarely with you. When a carer does use a PSC, HMRC's off-payroll working guidance and the CEST tool are the starting point, and a specialist keeps the determination on file. Treat IR35 as the narrow edge case it is, and put your attention on the status of the carers you engage directly.

What this means for you: getting carer status right

The fix is process, not luck, and most of it is straightforward once someone runs it properly. If you engage carers and you are not certain their status would survive a check, work through the steps below before HMRC or a tribunal does it for you.

1. Map how each carer really works. Control, substitution and mutuality decide status, so write down what actually happens on the rota, not what the contract claims. The reality wins every time.
2. Run CEST and keep the result. HMRC's Check Employment Status for Tax tool gives a view and, kept on file, is useful evidence. It does not test everything and does not always answer, so treat it as one input and take reasonable care alongside it.
3. Apply the agency rules. Even a borderline self-employed carer is usually pulled into PAYE by the SDC test in section 44 ITEPA. Assume payroll unless you have a genuine, documented exception.
4. Model the true cost before you switch. Employer National Insurance, holiday pay and pension change the number. Set the pay rate and rota so the carer's take-home stays fair and the agency margin still works.
5. Set up payroll properly. Register the PAYE scheme, auto-enrol eligible carers, and run compliant rolled-up holiday pay at 12.07 percent for irregular-hours staff. Per the 2024 holiday pay reforms, rolled-up pay is allowed for these workers.
6. Get a specialist to pressure-test it. A care accountant reviews the arrangements, fixes what is wrong, and represents you if HMRC ever asks. You can check your agency's position in a free call with LOYALS.

Done in this order, the switch from a risky self-employed model to compliant employment is calm and predictable. Left to chance, it surfaces as a holiday pay claim, a CQC staffing question or an HMRC letter, all of which arrive at the worst possible time and cost multiples of what prevention would have.
