Hairdresser Training: What's Actually Tax Deductible?

Every stylist invests in their craft. A balayage masterclass here, a barbering course there, a brand colour certification, the odd business or social-media workshop. The bills add up across a year.

So the question is fair: can you knock the cost off your tax bill?

The short answer is usually yes, but there's a line that catches people out. Training that keeps your existing skills sharp or adds to what you already do is normally deductible. Training that takes you into a genuinely new and unrelated business is not. Getting that distinction right is the whole game.

This guide is written for self-employed hairdressers, barbers, colourists and beauty therapists, whether you rent a chair, run a mobile round or own a salon. It uses the rules in force for 2026/27. If you'd rather hand the whole thing over, that's what we do for hairdressers and beauty businesses.

Is hairdresser training tax deductible?

Usually, yes. If you're self-employed, training that updates your existing expertise or adds new expertise within your current line of work (your existing business area) is an allowable revenue expense, so you deduct it against your trading profits. Training that's unrelated to what you already do, for example a course that lets you start a separate new business, is treated as capital and is not deductible. HMRC updated this guidance in 2024 to make the "existing business area" test clearer, and it's the test you live or die by.

What's the rule on training costs for the self-employed?

For any cost to be deductible, it has to clear two hurdles.

First, it must be incurred wholly and exclusively for the purposes of the trade. That's the statutory test in section 34 Income Tax (Trading and Other Income) Act 2005.

Second, it must be a revenue cost rather than capital. Day-to-day running costs are revenue and deductible. Costs that bring an enduring new asset or a new line of business into existence are capital, and you can't simply deduct those against profits.

Training sits right on that revenue-versus-capital fault line, which is why it gets confused so often.

HMRC's current position, set out in its Business Income Manual at BIM35660 (updated in 2024), is refreshingly practical. Training is revenue, and therefore deductible, where it "updates existing expertise or knowledge or provides new expertise or knowledge in the individual's existing business area."

That's broad on purpose. You don't have to prove the course only refreshed skills you already had. Adding a brand-new technique counts too, as long as it's within the business you already run.

The gov.uk guidance for self-employed expenses says the same thing in plainer words. You can claim training that helps you "improve skills and knowledge you currently use for your business" or "keep up to date with technology used in your industry."

Which stylist courses can you actually claim?

For a working hairdresser or barber, the great majority of professional training will be inside your existing business area, so it's deductible. In practice, that usually covers:

• Advanced cutting, barbering or styling courses.
• Colour technique training: balayage, foiling, colour correction, brand-specific colour certifications.
• Treatment and finishing courses such as keratin smoothing, perming or extensions, where you already offer or are extending hair services.
• Refresher and CPD courses that keep your technique and product knowledge current.
• Health and safety, hygiene and infection-control training for the salon.
• Business-side training that supports how you run the trade, for example bookkeeping, social-media marketing or salon-management courses.

The thread running through all of these is that they support the trade you're already carrying on. A mobile hairdresser taking a colour-correction masterclass is plainly improving the service they already sell. That's textbook deductible.

Business and admin training is worth calling out, because stylists often assume only the scissors-in-hand stuff counts. It doesn't. A course on running your books or marketing your chair is training that supports your existing business, so it's allowable on the same principle.

Which training is not deductible?

Here's the trap. Training is not deductible when it's unrelated to your existing business area, in particular where it equips you to start a new business or move into a new, unrelated field. HMRC treats that as capital expenditure, because what you're really buying is a new income-earning asset, not the upkeep of your current trade.

The line isn't about how advanced the course is. It's about whether it sits inside the business you already run.

A few examples of where stylists can stray over the line:

• A hairdresser who has never offered nails or aesthetics taking a full qualification to launch a separate, distinct treatment business. If that's a genuinely new and unrelated trade, the qualification cost looks capital.
• Training for a career change away from hairdressing altogether.
• A long qualifying course taken before you've started trading at all, to get yourself into the industry in the first place. The cost of acquiring the qualification that lets you set up shop is generally not an allowable revenue expense of the trade.

In practice, the closer a course is to what you already do, the safer the claim. Adding a beauty treatment that naturally extends an existing salon's services is usually fine. Buying a brand-new, standalone qualification to open a different kind of business is where HMRC is likely to say capital.

If you're unsure which side of the line a course falls on, that's exactly the kind of judgement call worth checking before you claim, not after.

What about kit, travel and the costs around the course?

The course fee is only part of the spend. The costs around it follow their own rules.

Travel and subsistence. If you travel to attend deductible training, the travel and reasonable subsistence are normally allowable too. If you use your own car, you can claim using HMRC's approved mileage rates: 45p per mile for the first 10,000 business miles in the tax year, then 25p per mile after that, for 2026/27. You can work out what a trip is worth with our mileage calculator.

Course materials. Books, manuals and consumables you use up on a deductible course are generally revenue and allowable.

Equipment you keep. Tools and equipment you buy and keep, say a new set of professional clippers, a colour-processing unit or salon furniture, are capital, not a running cost. You don't deduct them outright. Instead you can usually claim the Annual Investment Allowance, which gives 100% relief on qualifying plant and machinery up to £1,000,000 a year (the limit in place since 1 January 2019). For most stylists that means full relief in the year you buy the kit anyway, just through a different door.

So the course fee and a textbook are revenue deductions; the new clippers you bought to practise with are capital but usually fully relieved through the Annual Investment Allowance.

Illustrative example: a self-employed colourist's training year

Illustrative example. Priya is a self-employed colourist who rents a chair and trades as a sole trader. In 2026/27 she invests in her craft. Her training spend for the year:

Priya's deductible revenue training costs come to £1,040 (£450 + £280 + £150 + £70 + £90). As a sole trader paying Income Tax at the basic rate of 20% for 2026/27, that £1,040 deduction is worth £208 off her Income Tax bill (£1,040 x 20% = £208). She also saves Class 4 National Insurance at 6% on the same amount, another £62.40 (£1,040 x 6% = £62.40).

The £600 colour-processing unit is capital, so it isn't in that revenue total. But she can claim the Annual Investment Allowance on it and get 100% relief in the year of purchase, so in cash terms it's relieved in full too.

These figures are illustrative. Your own position depends on your profits, your marginal tax rate and your actual spend.

How does it work if you employ or train staff?

If you've taken on a junior or an apprentice, or you employ stylists in a salon, the picture changes in your favour.

The cost of work-related training you provide for your employees is an allowable business expense for you as the employer. On top of that, work-related training is specifically exempt from tax and National Insurance for the employee. As HMRC puts it, "you do not have to report anything to HMRC or pay tax and National Insurance if the employee is in work-related training." So funding a junior's cutting or colour course doesn't create a taxable benefit for them, and it's deductible for you.

That makes investing in your team genuinely tax-efficient, which is worth knowing if you're weighing up whether to grow.

Running payroll, tracking what's deductible and keeping the benefits side clean is fiddly once staff are involved. It's the sort of thing we take off salon owners' hands through our bookkeeping services, so training spend is claimed correctly and nothing slips through as an accidental benefit-in-kind.
