In short: a sole trader is quicker to set up and simpler to run, but you’re personally liable for the business’s debts. A limited company gives you legal protection and, once profits climb past roughly £30,000 to £50,000 a year, it usually becomes more tax efficient too. The right structure depends on your profit level, how much admin you want to take on, and how much risk you’re comfortable carrying.
When starting a business, one of the biggest decisions you’ll face is whether to operate as a sole trader or a limited company. The structure you choose affects your tax, legal protection, and even how professional your business appears to potential clients.
At Pixel Advertising, we work with growing businesses across the UK, and we know how important it is to get your setup right from day one. Here’s an easy guide to help you decide which structure fits your goals.
What is a Sole Trader?
A sole trader is the simplest way to run a business. You and your business are one legal entity, meaning you keep all profits after tax but are personally responsible for any debts or losses. If things go wrong, your personal assets, such as savings or property, could be at risk. However, setting up as a sole trader is quick and straightforward. You just need to register for Self-Assessment and file a tax return each year.
Pros of being a Sole Trader
- You keep all profits after tax
- Simple setup with minimal paperwork
- Tax efficient for smaller profits
- First-year losses can offset other tax owed
Cons of being a Sole Trader
- Unlimited personal liability
- Harder to raise business finance
- Less appealing to some clients
- Becomes less tax efficient as profits grow
What is a limited company?
A limited company is a separate legal entity from its owners. This means your personal assets are protected if the business runs into trouble. Shareholders and directors aren’t personally liable for company debts unless they’ve given a personal guarantee or committed fraud.
You can pay yourself through a salary and dividends, allowing for more flexible and often more tax-efficient income planning. However, a limited company comes with extra responsibilities, including annual accounts, Corporation Tax, and record-keeping.
Pros of a Limited Company
- Limited liability and asset protection
- More professional and credible image
- Easier to sell or transfer ownership
- Potential tax savings through dividends, especially at higher profit levels
- Option for multiple shareholders and directors
- Can make company pension contributions
Cons of a Limited Company
- More paperwork and annual filing
- Higher accountancy costs
- Complex tax and National Insurance rules
- Public information listed on Companies House
Tax comparison: Sole Trader vs Limited Company
For the 2026/27 tax year, sole traders pay Income Tax at 20% on profits between £12,571 and £50,270, 40% between £50,271 and £125,140, and 45% above that, on top of Class 4 National Insurance.
Limited companies pay Corporation Tax at 19% on profits up to £50,000 and 25% above £250,000, with marginal relief in between. Directors then typically draw a small salary plus dividends, which are taxed separately at lower rates.
This is where things shifted in 2026: dividend tax rates increased from 6 April 2026, while the dividend allowance stayed at just £500. That’s narrowed the gap between the two structures and pushed the point where a limited company reliably saves you money up to somewhere in the region of £30,000 to £50,000 of annual profit, depending on how much you draw out of the business and how much you leave to reinvest.
Below that range, the tax saving is often too small to outweigh the extra accountancy and admin costs of running a company. Above it, and especially once profits pass around £60,000, the gap tends to widen quickly in the limited company’s favour.
These figures are a general guide based on current 2026/27 rates and are not personal tax advice. Your own numbers will depend on how you draw income, so it’s always worth checking with an accountant before you decide.
How to choose the right structure for your business
Your decision depends on:
- How much profit your business makes
- How you want to pay yourself
- How much administration you’re comfortable managing
- How much personal risk you’re willing to carry
If you’re unsure, speak with an accountant or business advisor. They can help you work out which structure is most efficient for your situation and future plans.

Frequently Asked Questions
What’s the difference between a sole trader and a limited company?
A sole trader and their business are legally the same entity, so profits, debts and liability all sit with the individual. A limited company is a separate legal entity, which protects your personal assets but comes with more admin and reporting.
Is it better to be a sole trader or a limited company for tax?
It depends on your profit level. Below roughly £30,000 profit a year, staying a sole trader is usually simpler and the tax saving from incorporating is small. Above that, and especially past £50,000, a limited company tends to become more tax efficient.
How much has the 2026 dividend tax change affected the comparison?
Dividend tax rates rose from 6 April 2026, while the dividend allowance stayed at £500. This narrowed the tax advantage of running a limited company at lower profit levels, pushing the point where incorporating pays off higher than in previous years.
Can I change from a sole trader to a limited company later?
Yes. This process is called incorporation. It involves registering a new company with Companies House and transferring your business assets, contracts and goodwill into it, so many people start as a sole trader and switch once profits grow.
What are the main risks of staying a sole trader?
The biggest risk is unlimited personal liability. If your business runs into debt or is sued, your personal assets, such as your savings, car or home, could be used to cover it. A limited company protects you from this in most circumstances.
Do I need an accountant if I set up a limited company?
It’s not a legal requirement but strongly recommended. Limited companies face more complex tax, National Insurance and filing obligations than sole traders, and an accountant helps you stay compliant and make the most of tax-efficient options like salary and dividend planning.
