It's one of the most common questions we get asked at Rocket Accountants: "Should I be a sole trader or set up a limited company?" The honest answer is: it depends. But we can give you a clear framework to make the right decision for your situation.
| Factor | Sole Trader | Limited Company |
|---|---|---|
| Setup cost | Free | £12 + accountant fees |
| Tax on profits (basic rate) | 20–29% (Income Tax + NI) | 19–25% (Corporation Tax) |
| Personal liability | Unlimited | Limited to share capital |
| Admin burden | Low | Higher (annual accounts, CT600) |
| Credibility | Lower | Higher (esp. for contracts) |
| Pension flexibility | Limited | Employer contributions tax-free |
| Profit extraction | All taxed as income | Salary + dividends mix |
When a Sole Trader Structure Makes Sense
If you're just starting out, earning under £30,000 per year, or running a low-risk business, staying as a sole trader is often the simplest and most cost-effective option. The admin is minimal — you just need to file a Self Assessment tax return each year.
Sole traders in Essex who use our bookkeeping service find that keeping on top of their records throughout the year makes Self Assessment straightforward and stress-free.
Sole trader works well if:
- Annual profits are under £30,000–£35,000
- You're testing a business idea before committing
- Your business has minimal liability risk
- You want to keep admin simple and costs low
When to Incorporate as a Limited Company
The tax efficiency argument for incorporation typically kicks in when your profits exceed around £30,000–£35,000 per year. At this level, the Corporation Tax rate (19–25%) combined with a salary/dividend strategy can result in a lower overall tax bill than paying Income Tax and National Insurance as a sole trader.
Beyond tax, limited companies offer limited liability protection — your personal assets are protected if the business runs into financial difficulty. This is particularly important for contractors, consultants, and tradespeople working on larger projects.
Limited company works well if:
- Annual profits exceed £30,000–£35,000
- You want to retain profits in the business
- You need limited liability protection
- You're working with larger clients who prefer Ltd companies
- You want to bring in investors or co-directors

The Hidden Costs of a Limited Company
Before you rush to incorporate, be aware of the additional costs and obligations:
- Annual accounts must be filed at Companies House (usually requires an accountant)
- Corporation Tax return (CT600) must be filed with HMRC
- Confirmation statement required annually
- Director responsibilities under the Companies Act
- Payroll setup required if taking a salary
- Higher accountancy fees (typically £500–£1,500/year more than sole trader)
