Registering as Self-Employed: Step-by-Step Guide

Most beauty workers who rent a chair, work mobile, or run their own salon need to register as self-employed with HMRC. It's free, it takes about 10 minutes online, and it's one of those jobs that's far worse in your head than in real life. This guide walks you through exactly what to do, when to do it, and what happens next.

Quick rule of thumb: if you earn more than £1,000 a year from beauty work and nobody is deducting tax from your pay, you need to register.

Do you need to register?

You need to register as self-employed if:

• You rent a chair or booth in a salon
• You work mobile, visiting clients at home
• You run your own salon as a sole trader
• You do freelance beauty work (weddings, events, editorial)
• You earn more than £1,000 in a tax year from self-employed work

The £1,000 figure is your trading allowance. If you earn less than that in a full tax year (6 April to 5 April), you don't technically need to register. But if you're doing beauty work regularly, you'll almost certainly go past £1,000 quickly.

"But I'm only doing a few friends' nails on the side..." - if it's under £1,000 a year, you're fine. The moment it goes over, register. Don't wait until you're earning thousands and then try to backdate everything. HMRC does check, and the penalties aren't worth it.

Chair renters: if you pay rent to use a chair in someone else's salon and you find your own clients, set your own prices, and choose your own hours - you are self-employed. Full stop. The salon owner isn't your employer. You need to register.

Mobile workers: same applies. If you bring your own kit to clients' homes and they pay you directly, you're self-employed.

When to register

You must register by 5 October in the second tax year after you started working for yourself.

In practice, that gives you a surprisingly long window - but don't use it all. Here's why:

Our advice: register as soon as you start. Don't wait until the deadline. The sooner you register, the sooner you get your UTR number, and the sooner you can start keeping proper records and claiming expenses. Leaving it late just creates stress.

Tip for new starters: Set a phone reminder for two weeks after you register to chase your UTR letter if it hasn't arrived. You can call HMRC on 0300 200 3310 to check - have your National Insurance number ready and they can look it up in seconds.

What you need before you start

Get these ready before you sit down to register:

• Your National Insurance number - on your payslip, P60, or any letter from HMRC. If you can't find it, call HMRC on 0300 200 3500.
• Your name and date of birth (as HMRC knows them)
• Your address
• Your phone number and email address
• The date you started self-employment - even an approximate date is fine if you can't remember the exact day
• The nature of your business - "hairdresser," "beauty therapist," "barber," "nail technician," etc. Keep it simple.

You do NOT need:

• A business name (you can trade under your own name)
• A business bank account (though you should get one - see our guide on Business Banking for Beauty)
• Any qualifications or proof of training (though insurers will ask for these)

How to register: step by step

Option 1: Online (recommended - takes about 10 minutes)

1. Go to gov.uk/register-for-self-assessment
2. Click "Register if you're self-employed"
3. If you don't already have one, create a Government Gateway account. You'll get a User ID - write it down and keep it safe. You'll need this every time you log in.
4. Fill in your personal details (name, NI number, date of birth, address)
5. Enter the date you started self-employment
6. Describe what you do (e.g., "mobile hairdresser," "beauty therapist," "nail technician")
7. Confirm your details and submit

That's it. You're registered.

Option 2: By phone

Call HMRC's Self-Assessment helpline on 0300 200 3310. Lines are open Monday to Friday, 8am to 6pm. They'll take your details over the phone. Expect a wait - HMRC phone lines are not known for being quick.

Option 3: By post

You can download form CWF1 from gov.uk and post it to HMRC. This is the slowest option and there's really no reason to use it unless you can't get online.

What happens after you register

Your UTR number

Within 10 working days (sometimes up to 3 weeks), HMRC will send you a letter with your Unique Taxpayer Reference (UTR). This is a 10-digit number. It's yours for life.

Keep it safe. You'll need it to:

• File your Self-Assessment tax return
• Contact HMRC about your tax
• Set up payment plans
• Deal with your accountant (if you use one)

If you registered online, you might get your UTR faster - sometimes within 7-10 days. If it hasn't arrived after 3 weeks, call HMRC.

Your Government Gateway login

If you created a new Government Gateway account during registration, you'll also receive an activation code by post. You need this to finish setting up your online account. Don't throw it away.

Class 2 National Insurance

When you register as self-employed, HMRC automatically sets you up to pay Class 2 National Insurance. This is currently £3.50 per week (2025-26 rate) (2025/26 rate).

Class 2 NI is important because it counts towards your State Pension entitlement. Even though the amount is small, paying it builds up your pension record. You pay it through your Self-Assessment tax return, not separately.

If your profits are below the Small Profits Threshold (currently £6,725), you don't have to pay Class 2 NI - but you can choose to pay it voluntarily to protect your pension record. We'd recommend doing this.

You'll also pay Class 4 NI on your profits - see our guide on National Insurance: Self-Employed for the full breakdown.

Common mistakes to avoid

1. Not registering at all HMRC can charge you a penalty for late registration. More importantly, if you've been earning and not paying tax, you could end up with a big bill plus interest. Register early, stay on the right side.

2. Registering as a partnership when you're a sole trader If you work on your own, you're a sole trader. A partnership is when two or more people run a business together and share the profits. Most beauty workers are sole traders.

3. Confusing self-employment registration with Companies House Registering as self-employed with HMRC is for sole traders. If you want to set up a limited company, that's a separate process through Companies House. Most beauty workers don't need a limited company when starting out - see our guide on Sole Trader vs Limited Company.

4. Thinking you need to register separately for tax and NI When you register as self-employed, HMRC sorts both your Income Tax and National Insurance at the same time. One registration covers both.

5. Not keeping records from day one Start tracking your income and expenses from the moment you begin working. Even if you haven't received your UTR yet, keep notes of everything. You'll need this information when you file your first tax return.

Tip for new starters: Take a photo of every receipt the day you get it - product purchases from Sally Beauty, your chair rent payment, even parking when visiting a client. Receipts fade fast, and come January you'll be glad you did this from day one.

What if you're employed AND self-employed?

This is common in beauty. Maybe you work part-time at a salon on PAYE, and do mobile work on the side. Or you're employed in a completely different job and do beauty work in the evenings.

You still need to register as self-employed for the beauty work. Your employer handles the tax on your employed income. You handle the tax on your self-employed income through Self-Assessment.

When you file your return, HMRC works out your total tax across both incomes. You might end up paying more than you expected because your self-employed income pushes you into a higher tax bracket.

What if you've been working and haven't registered yet?

Don't panic, but don't ignore it either.

HMRC has a process for people who come forward voluntarily. It's always better to contact them yourself than to wait for them to find you. You'll likely need to:

1. Register now
2. File any outstanding tax returns
3. Pay any tax owed, plus interest
4. Possibly pay a penalty (though HMRC is often lenient with voluntary disclosures)

The longer you leave it, the worse it gets. If you've only missed a year or two, it's usually straightforward to sort out. Call HMRC on 0300 200 3310 or speak to an accountant.

What to do next

1. Register online at gov.uk/register-for-self-assessment - do it today if you haven't already
2. Save your Government Gateway User ID and password somewhere safe (not just on a sticky note)
3. Wait for your UTR - keep an eye on the post over the next 2-3 weeks
4. Start keeping records of all income and expenses from day one
5. Open a separate bank account for your business - see our guide on Business Banking for Beauty
