One of the most common questions for self-employed people in the UK is whether to operate as a sole trader or set up a limited company. The answer used to be straightforward — limited companies almost always paid less tax above a certain profit level. But the April 2026 dividend tax increase has changed the calculation. Here's how things stand in 2026/27.
The basic rate of dividend tax increased from 8.75% to 10.75%, and the higher rate from 33.75% to 35.75%, from 6 April 2026. This has narrowed — but not eliminated — the tax advantage of limited companies at most profit levels.
The Key Difference
As a sole trader, all your profits are subject to Income Tax and Class 4 National Insurance in the year they're earned. There's no separation between you and the business.
As a limited company, profits are subject to Corporation Tax (19–25%). You can then pay yourself a salary and dividends. Dividends don't attract National Insurance, which is where the tax saving comes from.

|---|---|---|

| NI on profits | Class 4: 6% / 2% | None on dividends |
| Dividend tax | N/A | 10.75% / 35.75% / 39.35% |

Take-Home Pay Comparison by Profit Level
The figures below assume the limited company director pays a salary of £12,570 and takes the rest as dividends. Sole trader figures include Class 4 NI. These are estimates — always consult an accountant for your specific situation.
| Annual Profit | Sole Trader take-home | Ltd Company take-home | Ltd advantage |
|---|---|---|---|
| £20,000 | ~£17,500 | ~£17,200 | Sole trader wins |
| £30,000 | ~£24,500 | ~£24,900 | ~£400 |
| £40,000 | ~£31,400 | ~£32,600 | ~£1,200 |
| £50,000 | ~£38,300 | ~£40,400 | ~£2,100 ✓ |
| £75,000 | ~£52,700 | ~£56,900 | ~£4,200 ✓ |
| £100,000 | ~£65,500 | ~£72,800 | ~£7,300 ✓ |
In 2026/27, the limited company structure typically starts to pay above around £35,000–£40,000 profit — but only after accounting for the additional accountancy costs of running a company (typically £500–£1,500/year more than sole trader accounts).
Other Advantages of a Limited Company
Tax isn't the only consideration. Limited companies also offer:
- Limited liability — your personal assets are protected if the business has debts
- Pension flexibility — the company can make pension contributions on your behalf, reducing corporation tax
- Income timing — you can choose when to pay dividends, allowing tax planning across years
- Professional perception — some clients prefer to work with limited companies
- IR35 considerations — if you work through agencies or for large clients, IR35 rules may affect your choice
Disadvantages of a Limited Company
- More administration — annual accounts, confirmation statements, corporation tax returns
- Higher accountancy costs — typically £500–£1,500 more per year than sole trader
- Less flexible — you can't just spend company money on personal expenses
- Director responsibilities — legal obligations under Companies Act
