Sole Trader vs Limited Company UK — The Core Difference
As a sole trader, you and your business are legally the same entity. You pay income tax and National Insurance on all business profits through your annual self-assessment return. There is no legal separation between your personal and business finances — if your business incurs a debt, you are personally liable for it.
As a limited company director, your business is a separate legal entity. The company pays corporation tax on its profits, and you pay personal tax on the money you extract — through salary and dividends. You have limited liability, meaning your personal assets are generally protected from business debts.
Sole Trader vs Limited Company UK — Which Pays Less Tax?
For most people, tax is the primary driver of the sole trader vs limited company decision. The key numbers for 2025/26 are:
| Tax / NI Type | Sole Trader | Limited Company Director |
|---|---|---|
| Income tax (basic rate) | 20% on profit above £12,570 | 20% on salary above £12,570 |
| National Insurance | Class 4: 6% (£12,570–£50,270) | Employer NI: 15% on salary above £5,000 |
| Dividend income | Not applicable | 8.75% (basic rate) above £500 |
| Main business tax | Income tax + NI on profits | Corporation tax: 19%–25% on profits |
Worked Examples — Three Income Levels
Example 1: £30,000 profit
At this level, the tax saving from a limited company is small — often eliminated entirely by the additional accountancy costs (typically £1,000–£2,000 per year more than a sole trader).
| Sole Trader | Limited Company | |
|---|---|---|
| Take-home pay | ~£23,500 | ~£24,100 |
| Tax saving | ~£600 — usually outweighed by extra accountancy cost | |
Example 2: £60,000 profit
Here the limited company advantage becomes meaningful — typically £2,000–£4,000 per year net of extra accountancy costs.
| Sole Trader | Limited Company | |
|---|---|---|
| Take-home pay | ~£42,000 | ~£45,000 |
| Net saving (after extra accountancy) | ~£1,500–£3,000 in favour of limited company | |
Example 3: £100,000 profit
At higher income levels, the limited company advantage is substantial.
| Sole Trader | Limited Company | |
|---|---|---|
| Take-home pay | ~£62,000 | ~£70,000 |
| Net saving (after extra accountancy) | ~£6,500–£8,000 in favour of limited company | |

✅ Rule of thumb for 2025/26
Below £30,000 profit: sole trader is simpler and likely cheaper overall. Between £30,000 and £35,000: use our calculator to find your exact position. Above £35,000: a limited company is usually more tax-efficient, with the saving growing significantly as profit increases.
Non-Tax Advantages of a Limited Company
Tax is not the only reason to incorporate. A limited company offers several other advantages:
- Limited liability: Your personal assets are generally protected from business debts and legal claims against the company
- Professional credibility: Some clients — particularly larger businesses and public sector organisations — prefer to engage limited companies
- IR35 compliance: If you work as a contractor, a limited company is required for outside IR35 work
- Pension planning flexibility: Employer pension contributions from a limited company reduce corporation tax and can be very tax-efficient
- Retained profits: You can leave profits in the company and draw them in future years at a lower tax rate
The Administration of Running a Limited Company
The main disadvantage of a limited company is the additional administrative burden compared to operating as a sole trader. A limited company must:
- File annual accounts with Companies House
- Submit a corporation tax return (CT600) to HMRC each year
- Run a PAYE payroll scheme for the director salary
- Produce dividend vouchers for each dividend payment
- File a confirmation statement with Companies House annually
- Maintain a registered office address
These obligations typically add £1,000–£2,000 per year in accountancy fees compared to a sole trader arrangement. Factor this into your tax saving calculation when deciding whether to incorporate.
⚠ Your financial information becomes public
When you operate a limited company, your annual accounts are filed at Companies House and are publicly available. Anyone can look up your company’s turnover, profit, and balance sheet. Sole trader financial information remains entirely private.
How to Switch from Sole Trader to Limited Company
Incorporating is straightforward — registering a limited company with Companies House costs £50 and takes approximately 24 hours online. Once registered, you need to:
- Notify HMRC that your sole trader business has ceased
- Open a business bank account in the company name
- Register the company for corporation tax with HMRC
- Set up a PAYE payroll scheme for your director salary
- File a final self-assessment return for your sole trader period
Most people engage an accountant at the point of incorporation to ensure everything is set up correctly from day one. See our guide on how to pay yourself from a limited company for the next steps once you have incorporated.
