The risk in plain terms
Most independent salons in the UK run a mix of employed staff and self-employed chair renters. That is completely legal, but only if the self-employed arrangement is genuine. HMRC does not simply read your contracts. It looks at how the arrangement actually works day to day, and if it looks too much like employment, it can reclassify your chair renters as employees, backdated.
This is not a fringe concern. The current wave of scrutiny traces back to the Supreme Court’s February 2021 ruling in Uber BV v Aslam [2021] UKSC 5, which found that Uber drivers were workers rather than genuinely self-employed contractors, largely because of how much control Uber exercised over their day to day work. That case was about employment rights rather than tax, but it hardened a principle that runs through both: the reality of the working relationship outweighs the label on the contract. Employment status across the gig economy, hairdressing included, has drawn closer attention since.
What HMRC actually checks
Going by HMRC’s own guidance on determining employment status and the way tribunals have applied it, the questions that matter are about real working practices, not paperwork. HMRC weighs control, personal service and the right to send a substitute, financial risk, and whether someone works exclusively for one place, then steps back and looks at the overall picture.
- 1
Can the stylist send someone else to cover their chair?
If a stylist is off sick or on holiday and cannot send a substitute in their place, the arrangement depends on their personal service. That points towards employment rather than a genuine business relationship.
- 2
Who sets the prices and the hours?
If the salon dictates opening hours, shift patterns, or what a cut and colour costs, that is control. Control is one of the strongest markers of employment there is.
- 3
Who actually collects the money?
A salon that takes every client payment through its own till and then pays the stylist a cut looks very different, in HMRC's eyes, to a stylist who takes their own payments and pays a fixed rent for the chair.
- 4
Is the stylist required to look and operate like staff?
Salon branded uniforms, salon-only product lines, and strict salon rules all narrow the gap between a renter and an employee. The more a stylist looks like staff, the more they may be treated as staff.
- 5
Can the stylist work elsewhere, or take clients outside the salon?
Exclusivity cuts against genuine independence. A real business can normally take work from more than one place, and can build a client list that belongs to them.
None of these factors is decisive on its own. Tribunals weigh the overall picture, so the more of them that apply to your salon, the greater the risk.
The real cost of getting it wrong
HMRC does not typically issue a flat fine. If a chair rental arrangement is reclassified as employment, the consequences stack up instead.
Backdated PAYE and National Insurance
Both employer's and employee's contributions, for as long as the arrangement has existed. That can reach back several years, across every chair affected.
Penalties on top of the tax owed
Scaled to how the error is judged: up to 30% of the tax owed for careless mistakes, up to 70% where it is judged deliberate, and up to 100% where it is judged deliberate and concealed.
Interest on everything owed
Charged from the date each payment should have been made, not from the date HMRC raises the question.
Those penalty bands are set out in HMRC’s compliance check factsheet CC/FS7A, which also explains how a penalty can be reduced if you tell HMRC about an error yourself before it asks.
For a salon with several chair renters over several years, this adds up to a genuinely serious bill. In some reported cases it has been enough to threaten the business itself.
How salon software fits into this, for better or worse
Here is the part that does not always get mentioned: your booking software can be part of the evidence.
If every stylist in your salon shares one login, one diary, and one till, with the salon effectively controlling who is booked in when and collecting all the payments centrally, that is a system that looks like the salon is running the stylists’ businesses for them, rather than the other way around. It does not cause the legal risk. It can make the risk harder to argue against if HMRC ever asks questions.
