Sole Trader vs Limited Company: Which Is Better?

The core difference

A sole trader and their business are legally the same entity. A limited company is a separate legal entity from its director/shareholder. This has profound implications for tax, liability, and how income is structured.

Tax comparison

At low profit levels (under ~£25,000), sole trader status is often simpler and not significantly more expensive than a limited company. Above £30,000 profit, the limited company route typically produces meaningfully better take-home pay:

The gap grows with income, primarily because of NI savings and the ability to take dividends at lower rates.

Limited liability

A limited company provides limited liability — your personal assets (home, savings) are protected if the company cannot pay its debts, as long as you have not personally guaranteed them. Sole traders have unlimited personal liability. This protection becomes more significant as turnover grows.

Admin overhead

A limited company has significantly more administrative obligations: annual accounts (Companies House + HMRC CT600), payroll (RTI), confirmation statement, VAT returns, company bank account, and formal dividend procedures. Sole traders file a Self Assessment return — that's largely it. Budget an additional £800–£2,000/year in accountancy fees for a limited company.

The breakeven point

Most accountants suggest the limited company structure pays for itself (in tax savings net of extra admin costs) at around £30,000–£40,000 profit. Below that, the admin burden may outweigh the benefit.
