Allowable expenses for threading, tinting and lamination, chair rent, PPE, record-keeping, NIC, VAT and MTD explained for UK self-employed brow technicians.
Brow work is a low-overhead, high-frequency trade. You might thread, tint, laminate and map a dozen pairs of brows in a day, taking a mix of card payments, contactless deposits, cash and the occasional tip, often split between a rented salon chair and a few mobile home visits. The tax problem is rarely a single big figure. It is the sheer number of small, fast transactions and the temptation to treat cash and tips as somehow outside the books. Get into the habit of logging every appointment and its consumables as you go, and the annual return becomes a tidy summary rather than a January scramble.
This guide is built around how a brow technician actually earns and spends: the consumables that drain a few pounds per client, chair or room rent, the PPE and insurance the job demands, and the mobile mileage many technicians rack up. Treat your income and costs accurately and you will pay tax only on real profit.
As a sole trader you pay Income Tax on profit, which is your total brow income minus allowable expenses. For 2025/26 the personal allowance covers the first GBP 12,570, then you pay 20% up to GBP 50,270, 40% to GBP 125,140 and 45% above, with the personal allowance tapering away between GBP 100,000 and GBP 125,140 to create an effective 60% band. Class 4 National Insurance is 6% on profit between GBP 12,570 and GBP 50,270 and 2% above, and Class 2 NIC is settled through Self Assessment.
Scottish brow technicians pay Scottish Income Tax on profit through six bands (19%, 20%, 21%, 42%, 45% and a 48% top rate) and carry an S-prefixed tax code, while National Insurance stays UK-wide. Welsh technicians have a C-coded tax code at rates currently matching the rest of the UK. If you also have a part-time PAYE job, perhaps a few salon shifts on an employed basis, your tax code can end up distorted, so run it through the tax code checker if anything looks off.
Plenty of brow technicians start small, taking a few clients in the evenings or at weekends around another job or while building a book of regulars. The GBP 1,000 trading allowance is made for this. If your gross self-employed income from all your beauty work is GBP 1,000 or less in a tax year, it is tax-free and you do not need to register for Self Assessment for it. Cross GBP 1,000 and you must register and report the full amount of your takings.
Once over the threshold you have a choice each year. You can deduct the flat GBP 1,000 trading allowance instead of working out actual expenses, which can suit a brand-new mobile technician with a tiny starter kit and almost no overheads. Or you can deduct your real allowable costs if they come to more than GBP 1,000, which is what almost every salon-based or busy mobile technician will do once chair rent, tints, kits and insurance are added up. You cannot use both, so total your costs and pick whichever leaves the lower profit.
An expense is allowable when it is incurred wholly and exclusively for the business. For a brow technician the list is dominated by consumables, rent and the protective kit the job requires.
| Expense | What qualifies | Notes |
|---|---|---|
| Consumables and product | Brow tints and developer, henna, threading thread, wax and wax strips, lamination and lash-lift kits, brow soap, mapping pencils, brushes and disposable applicators | Fully deductible; reorder little and often, so log as you buy |
| PPE and hygiene | Gloves, aprons, face masks, couch roll, sanitiser, disinfectant, sharps disposal, fresh towels and laundry | Allowable safety and hygiene costs central to the treatment |
| Tools and equipment | Tweezers, scissors, tint bowls, brushes, treatment couch, stool, ring light or lamp, magnifying lamp, trolley | Usually claimed in full via the Annual Investment Allowance |
| Chair or room rent | Weekly chair, station or treatment-room rent paid to a salon, fixed or percentage of takings | Often the single largest deduction for salon-based technicians |
| Home-office costs | HMRC flat-rate working-from-home allowance, or a fair share of heat, light and broadband if you work from home | Choose the larger fair deduction; not claimable alongside chair rent for the same work |
| Insurance | Public liability, treatment and professional indemnity cover | Allowable where it relates to the trade |
| Training and CPD | Courses that update or refresh existing skills, for example a new lamination system | Training into a brand-new trade is not allowable |
| Marketing and booking | Booking-app subscriptions, social media ads, business cards, website, before-and-after photo printing | Fully deductible running costs |
| Card and bank fees | Card-machine rental, transaction fees, business banking | Deduct the fee, record income gross before the fee |
| Travel and mileage | Mileage to mobile clients at HMRC's flat rate, or actual vehicle running costs | Ordinary commuting to a fixed salon base is not allowable |
If you rent a chair, station or room from a salon, that rent is a straightforward allowable expense, whether it is a fixed weekly figure or a cut of your takings. Keep the agreement and proof of each payment. If instead you treat clients from a room at home, you cannot claim chair rent but you can claim home-office running costs, either HMRC's simplified flat rate based on hours worked at home, or a fair proportion of heat, light and broadband based on the space used. Do the sum once and use the method that gives the larger fair deduction.
Many brow technicians work mobile, driving between clients' homes. You can claim 45p per business mile for the first 10,000 miles in the tax year and 25p thereafter, which keeps the records simple, or claim the actual running cost of the vehicle apportioned to business use. You cannot mix the two for the same vehicle in the same year, so keep a mileage log either way. The journey from home to a fixed salon base counts as commuting and is not allowable, but travel from one client to the next, or out to a mobile booking, is.
The private share of dual-use costs (your phone, broadband and car) must be excluded. Everyday clothing is never allowable, even a salon-branded outfit, because plain clothing is not protective wear. Personal grooming, your own brow treatments and gym memberships are private. And buying kit before your trade has actually started is pre-trading expenditure, claimed once you begin trading rather than lost.
This is where brow technicians most often slip up. Every form of payment is taxable income: card takings, contactless, bank transfers, cash and tips you keep. Booking deposits are income too, taxed in the period you earn the treatment. The accruals basis means a treatment done in late March that the client settles in April still belongs in the earlier tax year, so do not let the calendar at the salon door drift from your books.
The fix is to record income at the point of service, not from a bank statement months later. A statement will miss cash and tips entirely and will net off card fees, understating both your income and your deductible costs.
Keep it simple and consistent: log each appointment with the amount taken and the payment type, photograph or file every receipt for products and rent, and keep a running mileage note if you are mobile. Reconcile weekly while the bookings are fresh.
Take a salon-based technician renting a chair, with a busy book of threading, tinting and lamination clients and a few mobile bookings, taking GBP 32,000 across the year in card, cash and tips.
Income: GBP 32,000 (treatments GBP 30,400, tips GBP 1,600)
Allowable expenses:
Taxable profit: GBP 32,000 minus GBP 11,240 = GBP 20,760
Income Tax: GBP 20,760 minus GBP 12,570 = GBP 8,190 at 20% = GBP 1,638
Class 4 NIC: GBP 8,190 at 6% = GBP 491
Total tax and NIC: GBP 2,129 for the year, plus any Class 2 NIC due through Self Assessment. Run your own takings and costs through the sole trader tax calculator to sanity-check the figure, and if you also do a few employed salon shifts, the multiple-income calculator shows how the streams stack together.
For a brow technician, the money you forget to record costs more than the expenses you forget to claim. Log every appointment, tip and pot of tint as it happens, and the return writes itself.
You must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period, which most solo brow technicians never approach. Because nearly all your clients are members of the public who cannot reclaim VAT, registering would force you either to absorb 20% out of your own margin or to put your prices up by a fifth, which is a hard sell in a competitive local market. Voluntary registration rarely makes sense for a consumer-facing beauty business. Where to watch the threshold is if you grow: taking on stylists whose takings count toward your turnover, selling retail brow products, or running a heavy mobile round can push a thriving business closer than you expect, so track your rolling 12-month takings.
Making Tax Digital for Income Tax Self Assessment replaces the once-a-year return with quarterly digital submissions and a year-end finalisation. The thresholds are based on gross income, not profit:
For a brow technician this rewards the habit of recording as you go. Instead of reconstructing a year of fast, small appointments each January, you log takings and consumables digitally as they happen and send HMRC a summary every quarter. The appointment-led, many-small-payments shape of brow income, which makes an annual return painful, becomes far easier when it is captured continuously. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice.
Treating cash and tips as off the books. Both are taxable income. Failing to record them is the most common and most costly mistake in fast-paced beauty work.
Recording card takings net of fees. Report the gross amount the client paid and deduct the card-machine fee separately as an expense, otherwise your income and costs are both understated.
Missing chair rent records. Salon rent is often the biggest single deduction, so keep the agreement and proof of every payment rather than relying on memory.
Claiming everyday clothing. A smart or branded outfit is not protective wear and is never allowable; gloves, aprons and masks are.
Assuming a PAYE job's allowance covers brow income too. If employed salon shifts already use your personal allowance, every pound of brow profit is taxed from the basic rate up, so set money aside accordingly.
