Sole Trader or Limited Company?
How to Choose the Right Structure for Your Business
You’ve got the idea. You’ve found your first few customers. Maybe you’ve even registered a domain name.
Now comes the admin – and one of the first decisions you’ll need to make is this:
Should I operate as a sole trader, or set up a limited company?
At Edmonds Accountancy, we’ve helped hundreds of founders across Reading, Bracknell and the Thames Valley make the right decision for their business. Whether you’re launching a side hustle, turning freelance work into a full-time venture, or scaling a professional services business, the structure you choose will affect everything from how you’re taxed to how clients perceive you.
If you’re in Reading, Bracknell, or anywhere in the Thames Valley and trying to decide between the two, here’s what you need to know.
What’s the Difference Between a Sole Trader and a Limited Company?
| Sole Trader | Limited Company | |
| Legal identity | You are the business | The company is a separate legal entity |
| Tax | Income Tax and National Insurance | Corporation Tax, plus personal tax on dividends or salary |
| Admin | Simple to set up and manage | More complex reporting to HMRC and Companies House |
| Liability | You’re personally liable for debts | Your liability is limited to what you invest in the business |
| Perception | Often seen as informal or individual | Can appear more credible and established |
| Profits | All profits go to you | Profits belong to the company, then distributed |
These are just the structural differences. The decision also comes down to personal preference, your sector, and how you expect the business to grow.
You can find full guidance on setting up either structure at gov.uk.
Tax and Profit: What Makes the Most Financial Sense?
Tax efficiency is often a key factor, and this is where things get interesting. Sole traders are taxed on all profits through self-assessment, paying Income Tax and National Insurance. It’s straightforward, but as your profits increase, so does your tax bill.
With a limited company, the business pays Corporation Tax on profits. You then pay personal tax on any salary or dividends you take. It’s more complex, but can be more efficient once you’re earning upwards of £35,000 a year.
We often recommend clients run a comparison. There are online tax calculators that can give you a basic idea, but speaking to an accountant will give you a clearer picture based on your plans, not just your income.
When Should You Consider Changing from Sole Trader to Limited Company?
A lot of businesses start as sole traders. It’s fast, simple, and there’s less red tape. But it’s not always the best fit long term.
You might think about switching when:
- You’re earning consistently over £40,000 and want to reduce your tax bill
- You’re looking to build a brand beyond just yourself
- Clients expect or require you to be a limited company
- You’re hiring staff and want protection from liability
- You’re thinking about external investment or even a future exit
One of our clients – a freelance designer in Reading – came to us earning just under £50,000 as a sole trader. After incorporating, she saved over £5,000 in her first year through a better tax structure and began winning higher-value contracts with corporate clients.
That said, switching brings additional responsibilities. You’ll need to run a payroll if you’re paying yourself a salary, file statutory accounts, and manage two layers of taxation – one on company profits, and one on personal income. It’s not a reason to avoid it, but it’s worth knowing what you’re getting into.
What Are the Disadvantages of Being a Sole Trader?
The simplicity of being a sole trader is appealing – but it comes with trade-offs.
You’re personally liable for any business debts. That means your home, car, or savings could be at risk if something goes wrong. You also might find it harder to win larger contracts, particularly in industries where formal structure and longevity matter.
Tax-wise, once you’re into higher income brackets, you may end up paying more overall than a limited company director. You’ll also have fewer options for extracting profit or reinvesting in the business.
That doesn’t mean sole trader status is bad. For many self-employed professionals and side-hustlers, it’s a great place to start. But it’s important to revisit the decision regularly as your business evolves.
How to Decide: A Quick Checklist
If you’re not sure which way to go, ask yourself:
- How much do I expect to earn this year?
- Do I need liability protection, or am I comfortable with some risk?
- Will being limited make a difference to how clients view me?
- How much admin am I realistically prepared to take on?
- Am I planning to grow, hire, or raise funding in the next year or two?
The answers will often point you in the right direction.
How to Switch from Sole Trader to Limited Company
If you’ve been trading as a sole trader and want to incorporate, the process is simpler than most people expect. Here’s how it usually works:
- Register the company with Companies House, including a business name and registered office
- Set up a new business bank account, as company and personal finances must be kept separate
- Transfer existing assets or contracts, where needed
- Tell HMRC that you’re ceasing as a sole trader and register the company for Corporation Tax
- Start new accounting records from the date of incorporation
There’s no need to wait for the end of the tax year, but many clients find it easier to make the switch at a clean break point, such as 5 April or the start of a new quarter.
A good accountant will handle most of the heavy lifting – from company formation to setting up payroll and filing your first returns.

FAQs
What’s the legal difference between sole trader and limited company in the UK?
A sole trader is the business – legally and financially. A limited company is its own entity, and you operate as a director/shareholder.
Do I need an accountant to go limited?
Not legally, but it’s highly recommended. Mistakes in how you pay yourself or file accounts can cost you time and money.
Are there disadvantages to switching from sole trader to limited company?
There’s more admin, and your company’s financials will be on public record. But for many growing businesses, the benefits far outweigh the drawbacks.
Can I run both at once?
Yes. Some people operate both a sole trader and a limited company for different activities. Just make sure each has separate records and accounts.
