Mobile Barber Business: London Launch
UK Tax Setup
Registering Your Business
Now that you're running your own mobile barber business, your relationship with His Majesty's Revenue and Customs (HMRC) changes. You are no longer just an employee; you're a business owner. The first legal step is to register as a sole trader for Self-Assessment. This informs HMRC that you have untaxed income and are responsible for calculating and paying your own tax.
You will need to notify HMRC when you start working for yourself.
You must register by 5 October in your business's second tax year. For example, if you start your business between 6 April 2024 and 5 April 2025, you need to register by 5 October 2025. This process gives you a Unique Taxpayer Reference (UTR), which you'll need for all your tax dealings. Think of it as your business's national insurance number.
The Shift to Digital Tax
The way sole traders report their earnings is undergoing a major overhaul. The traditional annual tax return is being phased out in favour of a more modern, digital system called (MTD). For sole traders and landlords, this new system is known as MTD for Income Tax Self Assessment (ITSA). It's designed to make tax administration more effective and efficient.
MTD for Income Tax kicks in from 6 April 2026 for sole traders and landlords with qualifying income over £50,000, requiring digital record-keeping and quarterly updates instead of annual Self Assessment returns.
From April 2026, if your annual business or property income is above £50,000, you must follow MTD rules. This threshold drops to £30,000 from April 2027. Under MTD, you'll need to use compatible software to keep digital records of all your business income and expenses. Instead of one big annual tax return, you will send a summary of your income and expenses to HMRC every quarter. At the end of the year, you'll submit a final declaration to confirm your figures and make any accounting adjustments.
Understanding Your Contributions
As a self-employed barber, you'll pay tax on your profits, but you also need to pay National Insurance contributions. These payments build your entitlement to state benefits, like the State Pension. Sole traders pay two types of National Insurance: Class 2 and Class 4.
| Contribution | What It Is | How It's Paid |
|---|---|---|
| Class 2 | A flat weekly rate. You must pay this if your profits are over the 'Small Profits Threshold'. | Paid as part of your annual Self-Assessment tax bill. |
| Class 4 | A percentage of your annual profits above a certain threshold. | Calculated and paid along with your Income Tax through Self-Assessment. |
Class 2 is your ticket to qualifying for benefits, while Class 4 is essentially an additional tax based on how much you earn. HMRC will calculate what you owe for both classes when you file your tax return.
Beware of Payments on Account
One of the biggest financial shocks for new sole traders is the system. It's HMRC's way of collecting tax in advance for the upcoming tax year, ensuring you don't fall too far behind. If your Self-Assessment tax bill is over £1,000 and less than 80% of your income was taxed at source (which, as a mobile barber, it won't be), you'll need to make these advance payments.
Each payment is 50% of your previous year's tax bill. The deadlines are 31 January and 31 July. This means on your first 31 January deadline, you could be paying your tax bill for the previous year plus the first half of your estimated bill for the current year. This catches many people out, so it's vital to set money aside not just for the tax you owe, but for the advance payments too.
Getting your tax setup right from day one prevents future headaches. By registering correctly, understanding your National Insurance obligations, and preparing for Payments on Account, you build a solid financial foundation for your business.
