If you're thinking of working for yourself, becoming a sole trader is one of the easiest and fastest ways to start. Whether you're freelancing, running a small shop, or launching an online business, the sole trader route gives you full control with minimal red tape.
This simple setup guide walks you through the essentials of how to become a sole trader in the UK — step-by-step, with no fluffbest .
What Is a Sole Trader?
A sole trader is someone who runs their business as an individual. You're personally responsible for the business and its finances — including any debts or taxes. You get to keep all profits after tax, but you’re also liable if anything goes wrong.
It’s the most popular business structure in the UK, especially for freelancers, tradespeople, and side-hustlers just starting out.
1. Make Sure It’s the Right Fit
Before diving in, ask yourself:
Do I want to work independently?
Am I comfortable being personally responsible for the business?
Will I be earning money (not just running a hobby)?
If the answer is yes, the sole trader structure could be the perfect match.
2. Choose a Business Name
You can trade under your own name or choose a separate business name. A unique name helps you stand out and look more professional.
Tips for choosing a name:
Avoid anything offensive or misleading.
Don't include "Ltd", "Limited", or similar company terms.
Check that your name isn’t already trademarked or in use.
Make sure the domain name is available if you’re setting up a website.
3. Register with HMRC
You need to tell HMRC that you’re self-employed. This is a legal requirement and must be done by the 5th of October after the end of the tax year in which you start trading.
To register, you’ll need:
Your name, address, and date of birth
National Insurance number
Details about your business
The date you started trading
You’ll receive a Unique Taxpayer Reference (UTR) from HMRC, which you’ll use for submitting tax returns.
4. Understand Your Tax Responsibilities
As a sole trader, you’re responsible for managing and paying your own taxes. This includes:
Income Tax:
You’ll pay tax on profits over the personal allowance (currently £12,570).
National Insurance Contributions:
Class 2: If your profits are above £6,725.
Class 4: If your profits are above £12,570.
You report this via the Self Assessment tax return, due each year by 31 January (if submitting online).
5. Keep Good Records
You’ll need to keep detailed records of your income and expenses. This will help with your Self Assessment and ensure you’re prepared if HMRC asks for proof.
What to record:
Invoices and receipts
Sales and purchase logs
Bank statements
VAT records (if registered)
Digital accounting tools like QuickBooks, Xero, or FreeAgent can save time and reduce errors.
6. Open a Business Bank Account (Optional, but Recommended)
While not required, opening a business bank account helps you:
Separate business and personal expenses
Simplify tax calculations
Look more professional to clients
Many banks offer free business accounts for sole traders with low or no monthly fees.
7. Register for VAT (If Required)
If your turnover exceeds £90,000 in a 12-month period, you must register for VAT. Even if you're below the threshold, you can register voluntarily if you deal with VAT-registered clients.
Once registered, you must:
Charge VAT on your goods or services
Submit VAT returns (usually quarterly)
Keep digital records under the Making Tax Digital scheme
8. Get Insured
Insurance gives you peace of mind and protects your business from the unexpected.
Useful insurance types for sole traders:
Public Liability Insurance – covers accidents involving customers or the public
Professional Indemnity Insurance – for those offering advice or services
Employers’ Liability Insurance – required if you hire staff
Some clients or industries may require specific coverage before working with you.
9. Set Up a Pension (Optional but Smart)
Since you won’t be auto-enrolled in a workplace pension, it’s wise to set up your own. You can open a personal or self-employed pension plan and contribute regularly.
You’ll get tax relief on contributions, and it helps you build a safety net for the future.
10. Promote Your Business
Now that you’re set up, it’s time to attract customers. Here’s how to start strong:
Create a professional website or portfolio
Get listed on Google My Business
Use social media platforms to showcase your work
Ask for referrals and reviews from happy clients
The more visible and accessible you are, the easier it will be to grow.
11. Hire Help If Needed
As your business grows, don’t hesitate to bring in professional help — like a bookkeeper or accountant. They can save you time, help you avoid penalties, and make sure you’re claiming all allowable expenses.
Even a one-off consultation can be worth the investment.
12. Stay Informed and Compliant
Tax rules and thresholds change regularly. To avoid problems:
Keep an eye on HMRC updates
Review your earnings each year
Adjust your plans if your income crosses new thresholds
It pays to stay informed — literally.
Final Thoughts
Becoming a sole trader in the UK is one of the simplest ways to start a business. You can be up and running in a day, with low overheads and full control. By following this simple setup guide, you’ll have everything in place to focus on what really matters — growing your business.
Stay organised, keep track of your finances, and don’t be afraid to ask for help. You’ve got this.
