“Everyone here is self-employed.” That sentence makes me nervous not because it’s necessarily wrong, but because calling a martial arts instructor self-employed does not make them self-employed.
Whether a martial arts instructor is genuinely self-employed or actually an employee depends on the real working relationship control, payment structure, financial risk and substitution rights not on what the contract or invoice says. Get it wrong, and a club can face backdated PAYE, National Insurance, interest and penalties running into thousands of pounds.
You can put “self-employed” in the contract, ask for an invoice, or have them file a Self Assessment return. None of that settles the question. HMRC’s employment-status guidance is clear that status depends on the actual arrangement and the tax treatment can differ from the employment-law position.
For martial arts clubs, this matters more than people realise.
A typical club may have:
- A chief instructor;
- Several senior instructors;
- Assistant instructors;
- Somebody covering children’s classes;
- People paid £20 or £30 for helping out;
- And volunteers who gradually become regular paid coaches.
The arrangements usually evolve informally, one small payment at a time. Nobody sits down one Tuesday and decides to create an employment-tax problem it just happens.
Ten years later, everybody says “we’ve always done it this way.” That isn’t much of a defence.
Key Takeaways
- Status Depends on Reality, Not Labels: Contracts and invoices are not important, the working relationship is.
- HMRC considers several factors when determining status: Control, Substitution, Financial risk, Equipment and Integration.
- A false classification and a penalty will be expensive: both the employer and the employee as HMRC can claw back unpaid PAYE, NI, interest and penalties.
- Employment Status and Tax Status are different: An individual can have employment rights without tax status as well.
- Workers are not necessarily paid workers, but paid workers can be workers: Assistant Instructors and Volunteers Need Care.
- CEST Depends on Accurate Answers: The result will only be correct if the information given is correct.
- Update Paperwork: Do not fix a mismatch in the working arrangement by making changes to paperwork.
Are Martial Arts Instructors Self-Employed or Employees?
Either one club can legitimately employ some martial arts instructors while genuinely engaging others as self-employed contractors.
The answer is decided arrangement by arrangement, based on who controls the work, who carries the financial risk, and how integrated each martial arts instructor is into the club.
The First Rule: Employment Status Is Not a Choice
A martial arts instructor and a club cannot simply agree that the instructor is self-employed if the facts point towards employment.
There is no magic wording. HMRC looks beyond labels and considers the actual relationship, asking questions such as:
- Who decides when the instructor works?
- Who sets the timetable?
- Who decides what they teach?
- Who sets the price?
- Can they refuse work?
- Can they send somebody else?
- Who provides the premises and equipment?
- Who bears the financial risk?
- Who collects the students’ money?
- Is the instructor genuinely running a business of their own?
No single test decides it alone; you look at the arrangement as a whole.
This Isn’t Theoretical in Martial Arts
Clubs sometimes assume their unusual structure somehow takes them outside ordinary employment-status rules. It doesn’t.
Tribunals have considered cases involving sports coaches, and the principle is the same everywhere: paperwork describing someone as self-employed isn’t decisive if the working relationship points elsewhere.
I would never assess status simply by reading the contract. The contract is evidence, not the whole answer. If I really wanted to understand the arrangement,
I’d want to know who turns up every Tuesday, who tells them to be there, what happens if they don’t come, whether they can send a genuine substitute, and who actually gets the student’s fee. That tells you far more than any document.
The Main Employment-Status Tests, in Plain English
Tax law has accumulated plenty of case law here, but the practical questions that decide a martial arts instructor’s status are much easier to understand than the legal terminology suggests.
Control: Who Is Really in Charge?
Suppose your club tells an instructor:
- Teach every Wednesday from 6pm to 9pm;
- Wear our uniform;
- Teach our syllabus;
- Follow our class structure;
- Use our grading system;
- Attend instructors’ meetings;
- And obtain approval before changing anything.
That is quite a lot of control.
Compare that with someone who:
- Hires your dojo for two hours;
- Runs their own class;
- Sets their own prices;
- Chooses what they teach;
- Collects their own fees;
- Advertises independently;
- And simply pays you for using the space.
Those arrangements feel very different because they are.
Control is one important part of determining status. HMRC’s Employment Status Manual specifically treats matters such as control, personal service, financial risk and the overall circumstances as relevant to the assessment.
Mutuality of Obligation: Does the Club Have to Offer Work, and Does the Instructor Have to Take It?
Broadly, this asks whether there’s an ongoing obligation on each side. Does the club expect a fixed weekly commitment, and does the coach expect to be given that class? If the club cancelled their classes indefinitely without discussion, would everybody regard that as normal?
HMRC treats mutuality of obligation as relevant to whether a contract exists at all. A genuinely casual arrangement, where someone covers a class occasionally when available, is different from a fixed slot continuing year after year.
Personal Service: Can They Genuinely Send Somebody Else?
The right of substitution gets a lot of attention in status cases. Can an instructor genuinely phone another qualified coach and say “you take Thursday’s class, invoice the club instead”? If so, that supports self-employed status.
But a clause nobody would ever actually use isn’t persuasive. HMRC’s CEST tool examines exactly this for any martial arts instructor, and reality beats drafting every time.
Financial Risk: Can the Instructor Actually Make or Lose Money?
Employees generally get paid regardless of outcome; self-employed people carry commercial risk. If a martial arts instructor gets £25 a class whatever the attendance, while the club collects the fees and carries the risk, that instructor has very little skin in the game.
Someone who hires the hall themselves, charges students directly, and makes nothing if nobody turns up much like the independent coaches advertising their own sessions on sites such as Superprof looks far more like a business in its own right.
Now compare that with an instructor who:
- pays £300 a month to hire your premises;
- charges students directly;
- decides their own fees;
- pays for their own advertising;
- carries their own insurance;
- and makes nothing if nobody turns up.
That looks considerably more like somebody in business on their own account.
Equipment and Premises
Martial arts instruction isn’t particularly equipment-heavy, but the wider picture still matters. Who provides:
- The mats;
- Pads;
- Kick shields;
- Uniforms;
- Booking system;
- Website;
- Insurance;
- Venue;
- Safeguarding systems?
A martial arts instructor who arrives, teaches the club’s students on the club’s mats, and goes home with a fixed payment looks different from someone running an independent teaching business.
Integration: Are They Part of Your Club?
Does the instructor appear to everyone else to be part of your organisation?
For example:
- Club-branded uniform;
- Profile on the club website;
- Club email address;
- Fixed position on the timetable;
- Involvement in gradings;
- Instructors’ meetings;
- Responsibility for members;
- Representation of the club externally.
The more integrated a martial arts instructor is, the harder it is to argue they’re an independent supplier standing outside the club altogether.
Where Martial Arts Clubs Usually Get Caught
Rarely the contract usually the timetable and the money. A fixed weekly slot, a fixed per-class fee, and no real financial risk looks like employment whatever the paperwork says.
Consider a club:
- Sets all membership fees;
- Collects every student’s money;
- Owns the branding;
- Rents the hall;
- Provides the insurance;
- Sets the syllabus;
- Decides the timetable;
- Allocates an instructor every Tuesday and Thursday;
- And pays that instructor £30 per class.
That instructor:
- Cannot set their own price;
- Does not invoice students;
- Does not choose which classes exist;
- Does not bear any real commercial risk;
- And is expected to turn up every week.
Marking the invoice “self-employed instructor” in bold capitals doesn’t change the facts underneath. That arrangement has several features pointing towards employment.
But My Instructor Works for Three Other Clubs
Direct answer: that helps, but it doesn’t settle anything, because status is assessed relationship by relationship, not person by person.
An individual can be genuinely self-employed in one engagement and employed in another. A martial arts instructor might run their own academy Monday to Thursday, coach as an employee at a school on Friday, and take freelance seminar work at weekends nothing contradictory about that. GOV.UK confirms contractors can hold different statuses across different engagements. Being self-employed elsewhere doesn’t automatically make someone self-employed with you.
What About Assistant Instructors?
Direct answer: an assistant martial arts instructor who starts out helping for free can drift into worker or employee status without anyone noticing, because regular payment for regular attendance changes the legal character of the relationship even if everyone still calls it “expenses” or “pocket money.”
A junior black belt helps occasionally for nothing, then gets petrol money, then “£20 for the evening because they deserve something.” Six months later they teach twice a week for £40. At that point, ask what the arrangement has actually become genuine expense reimbursement is one thing; a regular payment for regular attendance is another, regardless of whether you call it an honorarium, pocket money or an allowance.
Volunteers Need Particular Care
Direct answer: a genuinely voluntary role usually sits outside worker status, but the moment it becomes regular, paid and expected, that protection starts to disappear.
Clubs genuinely depend on volunteers, and there’s nothing wrong with that. A volunteer who gives their time freely and receives only genuine reimbursement of expenses will usually sit outside worker arrangements. HMRC’s National Minimum Wage guidance recognises sports clubs commonly use volunteers, but warns that some arrangements create worker status needing proper assessment. The trouble starts when a “voluntary” role becomes contractual in practice regular work, regular payment, regular expectations.
Why Getting Status Wrong Can Become Expensive
Direct answer: if HMRC decides a martial arts instructor treated as self-employed should have been an employee, the club not the instructor usually carries the exposure: backdated PAYE and National Insurance, interest and penalties, potentially going back six years, or twenty for deliberate non-compliance.
It isn’t as simple as switching to payroll next month. HMRC can look backwards, calculating tax and National Insurance that should have been operated historically, plus interest, penalties, payroll corrections and professional fees to reconstruct everything. That exposure falls on the club, not the instructor, and can go back up to six years for ordinary errors, or twenty for deliberate non-compliance. Employer National Insurance has also become materially more expensive, rising to 15% from April 2025, making misclassification considerably less attractive than it once was.
For context, HMRC’s most recent tax gap report put the total UK tax gap at £39.8 billion for 2022–23 4.8% of all tax due with self-employed compliance identified as an area of continued focus. Separately, HMRC’s own employment-status research found that many working arrangements are genuinely hard to classify: among individuals whose status wasn’t immediately obvious, only around 6% were assessed as likely self-employed, with the majority leaning towards worker status. That’s exactly the grey area many martial arts clubs are sitting in without realising it.
Tax Is Only Half the Story
solving the tax question for a martial arts instructor doesn’t automatically solve the employment-law question, because the two sets of tests are separate and don’t perfectly align.
Some clubs assume that if HMRC accepts self-employed status for tax, the matter is finished. It isn’t. Employment law has its own separate tests, and the categories don’t perfectly align. A martial arts instructor may have worker rights National Minimum Wage, paid holiday, pension auto-enrolment even where the tax position looks different. So, a club can resolve one question and still have another waiting behind it.
“Everyone in Martial Arts Does It Like This”
Direct answer: possibly, but popularity isn’t a legal defence a common industry habit doesn’t change what the facts say about a martial arts instructor’s status.
Martial arts has plenty of traditional habits, and not all are recognised principles of UK tax law. None of the following is a defence: “every other dojo pays instructors this way,” “the instructor wants to be self-employed,” or “they’ve been putting it on their own return for years.” Employment status is determined from the facts, instructor by instructor.
Should Martial Arts Clubs Use HMRC’s CEST Tool?
Yes, as a useful starting point but CEST is only as reliable as the facts entered into it, and an inaccurate answer about control or substitution will produce a misleading result for a martial arts instructor.
CEST asks questions about the working arrangement and produces a status result for tax purposes. HMRC updated the tool in April 2025, stating the underlying technical principles were unchanged. Keep the result, a copy of the questions, and evidence supporting your answers. If you tell CEST an instructor can send any suitably qualified substitute when the club would never allow that, the problem isn’t the tool it’s the answer you gave it.
What Does a Genuinely Self-Employed Martial Arts Instructor Look Like?
A martial arts instructor who hires the space, sets their own prices, collects their own fees, carries their own insurance and financial risk, and could realistically be described as running an independent teaching business rather than filling a fixed slot in someone else’s timetable.
Features that support self-employment include hiring the dojo or paying a genuine mat fee, setting prices, collecting fees directly, marketing under their own name, holding their own insurance, carrying financial risk, having a genuine right to arrange cover, and teaching for multiple organisations. Contrast that with a fixed club timetable, fixed pay, club students, club uniform, club syllabus, no meaningful substitution and no financial risk the pattern that catches out far more clubs, and far more instructors, than the reverse.
Don’t Redesign Reality Just to Save PAYE
The goal isn’t to manufacture self-employment for a martial arts instructor on paper it’s to identify the commercial relationship the club genuinely wants and structure it honestly.
There’s a temptation, on reading a list like that, to think “we’ll just add a substitution clause and make them buy their own pads.” That misses the point. If you want people who commit to regular classes, follow your system, and represent your club, employment may genuinely be the cleaner structure.
It costs more and creates responsibilities, but it also gives legitimate control and clarity. Trying to keep the benefits of employment while avoiding the obligations is where disputes begin.
When a Self-Employed Arrangement Stops Working for Your Club
A self-employed arrangement stops working the moment a martial arts instructor becomes a fixed, recurring part of your teaching team same nights, your syllabus, no financial risk of their own because at that point the label no longer matches the substance of the relationship.
Watch for the warning signs: a “self-employed” instructor who has taught the same two nights for years, wears your uniform, follows your syllabus, can’t set prices or recruit their own students, and gets paid the same whether five or twenty-five people show up. Or an assistant whose “expenses” have quietly become a weekly wage. Or a volunteer now effectively running a class on a permanent Rota.
None of this usually happens dishonestly a club’s needs typically change gradually, while the paperwork stays frozen at the point the relationship began. Updating the wording without changing the underlying relationship doesn’t change the answer; both HMRC and an employment tribunal look through the label to what’s actually happening.
If this sounds like your club, a proper review covering how each person is engaged and whether payroll or a different structure is the right way forward is far better done on your own initiative than prompted by HMRC or a claim.
A Practical Example
Direct answer: two instructors doing the same job in the same building can land on opposite sides of the self-employment line, depending entirely on who controls the class, who sets the price, and who carries the risk.
A karate club with 180 members: the owner teaches three evenings, and two senior instructors cover the rest. Each has taught the same nights for five years, gets £50 an evening, wears the club uniform, teaches the club syllabus, can’t set prices or recruit students, must clear absences with the chief instructor, and gets paid regardless of attendance. They invoice monthly, marked “self-employed instructor.” Would I rely on those invoices alone to establish self-employment? No I’d want a proper review.
Now change the facts. A Brazilian Jiu-Jitsu coach independently hires the dojo every Sunday, advertises their own sessions, charges attendees directly, holds their own insurance, sets their own fees, keeps any profit, absorbs any loss, and arranges their own cover. Same building, same broad industry a completely different relationship, and a completely different answer for that martial arts instructor.
What Should an Established Martial Arts Club Do Now?
If you pay any martial arts instructor outside of payroll, review every arrangement against the facts not the paperwork starting with who controls the timetable, who collects the fees, and who genuinely carries the financial risk.
For every martial arts instructor, ask:
- Who controls the timetable and teaching?
- Who sets prices and collects fees?
- Is there an obligation to provide and accept work?
- Can the instructor genuinely provide a substitute?
- Who carries financial risk, and who provides equipment and insurance?
- How integrated are they into the club and could they realistically be described as running their own business?
Then make sure the written agreement reflects what actually happens. Not what you wish happened.
What If We’ve Been Getting It Wrong?
Don’t panic, but don’t ignore it either establish whether there’s a real problem first, then fix the substance of the relationship before you fix the paperwork.
Employment status is fact-sensitive, and genuinely borderline situations exist. Take advice about correcting the position going forward, any historical exposure, disclosure, payroll, contracts, and pension duties. Fix the substance first. Then fix the paperwork.
The Bigger Financial Question for Martial Arts Clubs
Paying a martial arts instructor correctly would make the club unprofitable, the real problem usually isn’t the tax classification it’s that membership fees were set without properly accounting for the true cost of delivering classes.
Many clubs price membership without properly accounting for that cost. A £50 monthly fee that only works because coaches are informally paid below the true employment cost may simply be the wrong price. The fix may involve membership fees, class structure, instructor utilisation, timetable design, payroll planning or venue costs. Compliance shouldn’t destroy a viable club, but it sometimes reveals the economics were weaker than they looked useful information, even when unwelcome, and exactly the kind of review our payroll and business advisory team can work through with you before HMRC does it instead.
It’s also worth remembering that qualifications and governing-body recognition the coaching standards set out by bodies such as the British Martial Arts and Boxing Association are about competence and safeguarding, not employment status. A well-qualified martial arts instructor can still be misclassified for tax purposes; the two questions are entirely separate.
The Question I Would Ask
Forget the contract, forget the UTR, forget what everyone else in the sport does. Imagine a tribunal sat quietly at the back of your dojo for a month, watching who opened the building, who collected the money, who set the timetable, who gave instructions, who wore whose branding, who carried the financial risk, and what happened when someone couldn’t attend. At the end of the month, what relationship would they say they’d actually watched? That’s the question that matters.
Unsure Whether Your Martial Arts Instructors Are Really Self-Employed?
At Carter Collins & Myer, we work with owner-managed businesses, clubs, charities and community organisations across Rochdale, Greater Manchester, Lancashire and Cheshire.
We can review how your instructors are currently engaged, look at the tax and payroll implications, and check the paperwork genuinely matches how the club operates. If it isn’t, it’s far better to find out during a sensible review than during an HMRC compliance check or a tribunal claim.
