Electrologist
Tax & MTD Guide
Allowable expenses on probes, machines and PPE, chair or room rent, cash record-keeping, VAT and MTD for Income Tax explained for UK self-employed electrologists.
- Electrolysis is a cash-and-card service trade, so the biggest tax risk is under-recording takings (especially cash tips and walk-ins) rather than missing an expense.
- If your gross electrolysis income tops GBP 1,000 you must register for Self Assessment; below that the trading allowance covers you, and you can deduct the GBP 1,000 instead of expenses if it gives a lower profit.
- Your core deductions are consumables and kit: disposable probes, the electrolysis machine via the Annual Investment Allowance, sterilisation, PPE, after-care products and chair or room rent.
- You pay Income Tax plus Class 4 and Class 2 National Insurance on profit, all settled through Self Assessment, with Scottish and Welsh rates differing on tax but not on NIC.
- MTD for Income Tax applies from April 2026 above GBP 50,000, April 2027 above GBP 30,000 and April 2028 above GBP 20,000, tested on gross income not profit.
Electrolysis is the only permanent hair-removal method recognised in the UK, and the self-employed electrologists who provide it usually work in one of three ways: renting a room or couch space in a salon or clinic, running a treatment space from home, or travelling to clients as a mobile practitioner. Whichever model you use, the tax picture is the same trade with the same quirks: lots of small appointments, a meaningful slice of cash, regular spending on consumables, and a kit cost that can run into thousands when you buy a professional machine.
This guide is built around how an electrologist actually earns and spends: how your profit is taxed, the specific probes, machine, sterilisation, PPE and room-rent costs you can deduct, the record-keeping that keeps cash takings honest, National Insurance, VAT and the MTD timetable. Get the bookkeeping right at the couch and the annual return becomes a formality.
How Tax Works for a Self-Employed Electrologist
As a sole trader you pay Income Tax on your profit, which is your total takings minus allowable expenses. For 2025/26 the personal allowance covers the first GBP 12,570, then you pay 20% 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, while Class 2 NIC is settled through Self Assessment and protects your State Pension record.
Scottish electrologists pay Scottish Income Tax on their 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 electrologists have a C-coded tax code at rates currently matching the rest of the UK. If you also have a part-time PAYE job at a salon and your code looks wrong, run it through the tax code checker so you are not over- or under-taxed on the employed side.
The Trading Allowance and Starting Out
Many electrologists begin part-time, taking a few evening clients while keeping a salaried job. The GBP 1,000 trading allowance is built for exactly this. If your gross self-employed income from electrolysis is GBP 1,000 or less in a tax year, it is tax-free and you do not need to register for Self Assessment. Cross GBP 1,000 and you must register and report the full amount, including every cash appointment.
Once over the threshold you choose each year. You can deduct the flat GBP 1,000 trading allowance instead of working out actual expenses, which suits a brand-new mobile practitioner with little kit. Or you can deduct your real allowable expenses if they exceed GBP 1,000, which almost always wins the moment you buy a professional electrolysis machine or start paying room rent. You cannot do both, so total your costs and pick whichever leaves the lower profit.
Allowable Expenses for Electrologists
An expense is allowable when it is incurred wholly and exclusively for the business. For an electrologist the list is dominated by consumables, the machine itself, hygiene and room costs rather than office gear.
| Expense | What qualifies | Notes |
|---|---|---|
| Disposable probes and needles | Single-use electrolysis probes, needles and probe holders | Fully deductible consumables; buy in bulk and log it |
| Electrolysis machine | Galvanic, thermolysis or blend machines and the magnifying lamp | Usually claimed in full via the Annual Investment Allowance |
| Sterilisation and hygiene | Autoclave, sterilising pouches, disinfectant, couch roll, surface wipes | Core running cost for a treatment trade |
| PPE | Gloves, masks, aprons and eye protection | Fully allowable protective equipment |
| After-care and products | Soothing gels, antiseptic, cotton, tweezers and consumable tools | Deductible where used on clients |
| Chair or room rent | Weekly rent for a treatment room, couch or chair in a salon | Fully deductible; keep the agreement and receipts |
| Laundry and linen | Towels, couch covers and the cost of washing clinic linen | Allowable; keep a simple log if washing at home |
| Insurance | Professional indemnity, public liability and treatment cover | Fully deductible |
| Professional bodies | BABTAC, BIAE, the Institute of Electrolysis or similar membership | Allowable where relevant to the trade |
| Training and CPD | Courses updating your existing electrolysis and hygiene skills | Training into a brand-new trade is not allowable |
| Software and card fees | Booking systems, card-machine and payment-processing fees | Fully deductible business costs |
| Travel and mileage | Mileage to mobile appointments at 45p per mile (first 10,000) | Ordinary commuting to a fixed rented room is not |
Room Rent vs Home Working
How you claim your premises cost depends on your set-up. If you rent a room, couch or chair in a salon or clinic, the rent is a straightforward allowable expense, including any element for towels, reception or product use. Keep the rental agreement and every receipt, because this is often paid weekly in cash and is the easiest figure to lose. If instead you treat clients from home, you claim home-office running costs: either HMRC's simplified flat rate based on hours worked at home, or a fair proportion of heat, light, water and broadband based on the room used. Do the sum both ways once and use the larger fair deduction.
What You Cannot Claim
The private share of any dual-use phone, broadband or car must be excluded. Everyday clothing is never allowable, even a smart tunic, because only genuine protective wear or branded uniform counts. Your own beauty treatments, gym membership and general grooming are personal, not business. And the cost of getting set up before you actually start trading is pre-trading expenditure, claimed once you begin rather than ignored.
Record-Keeping: The Cash Problem
Electrolysis is a high-volume, low-ticket service and a real share of payment still arrives as cash and tips. HMRC pays close attention to cash-based beauty trades, so your records need to be tight. Bank your cash regularly so takings match deposits, keep a daily appointment-and-takings log (your booking software usually does this for you), and record tips as income. On the spending side, keep every receipt for probes, products and rent, and a mileage log if you are mobile. To see how your takings translate into a tax bill, run the figures through the sole trader tax calculator before you file.
For an electrologist, the pound you forget to bank costs more than the probe you forget to claim. Record every appointment and tip as it happens, and the cash never goes missing at return time.
Multiple Income Streams
Many electrologists do not earn from electrolysis alone. You might add waxing, threading or laser, sell after-care products, train other therapists, or hold a part-time PAYE job at a salon. These are not all taxed the same way, so use the multiple-income tax calculator to see how they stack.
| Income type | How it is usually taxed | Watch out for |
|---|---|---|
| Electrolysis treatments | Self-employment trading income | Record cash and tips, not just card takings |
| Other beauty services | Same self-employed trade | Combine into one set of accounts |
| Retail product sales | Trading income | Stock you buy to resell is a cost of sale |
| Training other therapists | Trading income | Often a separate, lumpier income stream |
| Part-time PAYE salon shift | Employment income, taxed at source | Your tax code may already use your allowance |
If a salaried or PAYE salon job already uses your GBP 12,570 personal allowance, every pound of electrolysis profit is taxed from the basic rate up, so set money aside rather than assuming the first chunk is tax-free.
National Insurance for Electrologists
On top of Income Tax you pay two classes of National Insurance, both collected through Self Assessment. Class 4 is 6% on profit between GBP 12,570 and GBP 50,270 and 2% above. Class 2 is a flat weekly charge that builds your entitlement to the State Pension and certain benefits; if your profit is below the small-profits threshold you can usually pay it voluntarily to keep your record intact, which is often worth doing.
- Annual Investment Allowance (AIA)
- A capital allowance that lets a sole trader deduct the full cost of qualifying equipment in the year of purchase rather than spreading it over several years. For an electrologist this typically covers your electrolysis machine, magnifying lamp, treatment couch, autoclave and trolley. Buy a GBP 3,000 machine and you can usually set the whole GBP 3,000 against your profit in that tax year, which can sharply cut the bill in your start-up or upgrade year.
Worked Example: An Electrologist on GBP 32,000
Take a practitioner renting a room two days a week, with a mix of electrolysis and a little waxing, taking GBP 32,000 over the year including cash.
Income: GBP 32,000 (electrolysis GBP 26,000, waxing and products GBP 6,000)
Allowable expenses:
- Electrolysis machine and lamp (AIA, claimed in full): GBP 2,800
- Probes, after-care products and consumables: GBP 1,400
- Sterilisation, PPE and couch roll: GBP 600
- Room rent (two days a week): GBP 4,800
- Insurance and professional membership: GBP 450
- Booking software and card fees: GBP 350
- Laundry, training and accountancy: GBP 700
- Total expenses: GBP 11,100
Taxable profit: GBP 32,000 minus GBP 11,100 = GBP 20,900
Income Tax: GBP 20,900 minus GBP 12,570 = GBP 8,330 at 20% = GBP 1,666
Class 4 NIC: GBP 8,330 at 6% = GBP 500
Total Income Tax and Class 4 NIC: roughly GBP 2,166 for the year, plus Class 2 NIC. Note how the AIA on the machine and the room rent do most of the work in bringing profit down. Sanity-check your own figures with the sole trader tax calculator.
VAT for Electrologists
You must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period, which most solo electrologists never approach. Be aware that electrolysis is a standard-rated cosmetic service, not a VAT-exempt medical treatment, so all of your takings count towards the threshold. If you do register you charge 20% VAT on treatments and reclaim VAT on machines, probes and products. Because your clients are mostly consumers who cannot reclaim it, voluntary registration usually just makes you 20% more expensive or eats your margin, so it rarely makes sense below the threshold.
MTD for Income Tax: What Changes for Electrologists
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:
- April 2026: Combined self-employment and property income over GBP 50,000
- April 2027: Over GBP 30,000
- April 2028: Over GBP 20,000
For a busy electrologist this is actually a help. Instead of reconstructing a year of cash takings and probe receipts each January, you record each appointment and cost digitally as it happens and send HMRC a summary every quarter. The continuous habit is exactly what a high-volume cash trade needs. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice.
Common Mistakes Electrologists Make
Not banking and recording cash. A meaningful share of takings is cash and tips; leave it out and your declared income will not match your lifestyle or deposits.
Missing the room rent. Weekly cash rent for a couch or chair is fully deductible but easily forgotten. Keep the agreement and receipts.
Forgetting the machine claim. A professional electrolysis machine can usually be written off in full via the Annual Investment Allowance in the year you buy it.
Treating electrolysis as VAT-exempt. It is a standard-rated cosmetic service, so all takings count towards the GBP 90,000 threshold.
Assuming a PAYE salon job covers the allowance. If employment already uses your personal allowance, your self-employed profit is taxed from the basic rate up.
