Self-Assessment for Beauty Therapists: Complete Guide

If you're a self-employed beauty therapist, nail technician, aesthetics practitioner, or lash tech, you need to file a Self-Assessment tax return every year. This guide focuses on the expenses and situations specific to beauty therapy, nails, and aesthetics - so you're claiming everything you're entitled to and not paying more tax than you should.

Quick rule of thumb: if nobody is deducting tax from your pay before you get it, you need to file a Self-Assessment return. Don't leave money on the table - claim every legitimate expense.

The basics: deadlines, registration, and filing

The core Self-Assessment process is the same whether you're a hairdresser, beauty therapist, or nail tech. Our guide on Self-Assessment for Hairdressers covers the shared content in detail:

• Registering with HMRC and getting your UTR number
• Tax year dates (6 April to 5 April)
• Key deadlines (31 January for online filing and payment, 31 July for payment on account)
• Penalties for late filing and late payment
• Step-by-step filing online through your Government Gateway account

If you haven't read that guide yet, start there for the mechanics. This guide focuses on what's different for beauty therapists, nail techs, and aesthetics practitioners - particularly expenses.

Beauty-specific expenses you can claim

This is where it gets interesting. Beauty treatments use a lot of products and specialist equipment, and all of it is claimable if it's for business use. Here's a detailed breakdown by category.

Treatment products (consumables)

These are products you use up during treatments. They're fully claimable as business expenses.

Keep every receipt. Even the £4.99 pack of spatulas from Sally Beauty. It all adds up.

Tip for new starters: In your first year, photograph every receipt the day you get it - use your accounting app or phone camera. Paper receipts from beauty wholesalers fade fast, and you need to keep records for at least 5 years. A quick snap takes 5 seconds and could save you hundreds in missed claims.

Disposable items

These might seem small individually, but a busy beauty therapist could easily spend £300-£600/year on disposables alone. Claim it all.

Specialist equipment

Larger equipment purchases can be claimed as capital allowances (see our Tax-Saving Strategies guide). Under the Annual Investment Allowance (AIA), you can deduct the full cost of qualifying equipment in the year you buy it, up to £1,000,000 - so for beauty workers, this effectively means everything is fully deductible.

Tip: If you buy a large piece of equipment, keep the receipt and note the date you started using it for business. If you also use it personally (unlikely for most beauty equipment), you can only claim the business-use percentage.

Mobile kit costs

If you're a mobile beauty therapist, your kit costs are higher because you're carrying everything with you. All of these are claimable:

• Carry cases and bags for equipment
• Portable couch / massage table
• Portable UV lamp
• Travel sterilisation kit
• Towels (dedicated to business use)
• Table / trolley (portable)

Laundry and uniform

• Towels and gowns: if you wash business towels at home, you can claim a reasonable amount for laundry costs. HMRC doesn't publish a fixed rate for this, but a common approach is to estimate the cost per wash (detergent + water + electricity) and multiply by the number of washes per week.
• Uniform / workwear: if you wear specific clothing that's clearly for work (branded tunic, scrubs), the cost is claimable. Everyday clothing is not - even if you only wear it to work.

Working out your profit

Your taxable profit is:

Total income - Total allowable expenses = Profit

This is the number HMRC taxes you on. The more legitimate expenses you claim, the less tax you pay.

Example - beauty therapist earning £30,000/year:

That's a tax bill of £1,562 on £30,000 income. Without claiming expenses, the bill would be about £4,900. Claiming everything you're entitled to saves you over £3,300/year in this example.

Expenses unique to each beauty specialism

Nail technicians

• Acrylic liquid and powder, UV gels, BIAB, gel polish

• Extraction/ventilation equipment
• Dust collector/vacuum

Lash technicians

• Individual lash extensions (classic, hybrid, volume)
• Lash adhesive and remover
• Micro brushes, disposable mascara wands
• Under-eye gel pads / tape
• Lash shampoo
• Tweezers (replace as they wear out)
• Lash bed / couch

Aesthetics practitioners

• Injectable products (fillers, Botox - if you prescribe or purchase through a prescriber)
• Microneedling cartridges/heads
• Chemical peel solutions
• Numbing cream (prescription or OTC)
• Sharps disposal (clinical waste collection)
• Cannulas, needles, syringes
• Sterile drapes and gloves

Spray tan technicians

• Tanning solution

• Disposable items (thongs, hairnets, sticky feet)
• Extraction fan/tent
• Spray tan machine (capital allowance)
• Filters and cleaning supplies

Tips and cash payments

Tips are taxable income. Whether a client adds £5 to their card payment or slips you a tenner in cash, it counts as income and must be declared on your tax return.

Cash payments must be recorded. If a client pays you £40 cash for a set of lashes, that £40 goes in your income record. HMRC can and does investigate beauty workers - particularly those in cash-heavy specialisms. If your lifestyle doesn't match your declared income, they'll notice.

This isn't about being paranoid. It's about keeping clean records so that if HMRC ever does ask, you can show them everything and they move on.

Filing your return: step by step

1. Gather your records - income total, expenses by category, bank statements
2. Log into your Government Gateway account at gov.uk
3. Complete the self-employment pages (SA103 supplementary pages - these are included in the online form)
4. Enter your income (total turnover)
5. Enter your expenses - either as a single total, or broken down by category (broken down is better - it shows HMRC you've kept proper records)
6. Check HMRC's calculation of your tax bill
7. Submit - you'll get a confirmation
8. Pay by 31 January (and 31 July if you have payments on account)

Can you file yourself or do you need an accountant? If your affairs are simple - one source of self-employed income, straightforward expenses - you can absolutely file yourself using the online system. It walks you through it.

If you have multiple income sources, complex expenses, or you just find the whole thing stressful, an accountant is worth the money. Typical cost for a sole trader: £150-£400/year.

Payment methods: don't get caught out

You can pay your tax bill by:

• Direct debit - set it up through your online account
• Bank transfer - use the details on your statement
• Budget payment plan - pay a fixed amount monthly throughout the year (set this up through your HMRC account)
• Debit card - online through HMRC
• Credit card - no longer accepted by HMRC directly, but you can use third-party services (fees apply)

Avoid the January shock: if this is your first year filing, you'll pay your tax bill for the current year PLUS a payment on account for the next year. This can mean paying roughly 150% of what you expected. See our guide on Payments on Account Explained.

Tip for new starters: Set up a standing order on the day you start earning to move 25-30% of your weekly takings into a separate savings account. When your first tax bill lands in January, the money will already be there. The beauty workers who get into trouble are the ones who spend everything and scramble to find thousands in January.

What to do next

1. Read the Self-Assessment for Hairdressers guide for the core process (deadlines, registration, step-by-step filing)
2. Go through the expense categories above and check you're claiming everything
3. Set up a record-keeping system if you haven't already - see our Setting Up Record-Keeping guide
4. Put 25-30% of your profit aside for your tax bill throughout the year
5. File early - you don't have to wait until January. You can file from 6 April onwards for the previous tax year.
