Sole Trader vs Limited Company: Which Should You Choose?

A sole trader runs a business personally. A limited company is legally separate from its owners. The better structure depends on your business risks, profits and how much administration you want.

This explanation focuses on UK businesses.

Lowdown

A sole trader and their business are legally the same person. A limited company is a separate legal entity, owned by its shareholders and run by its directors.^[1]

Why It Matters

Liability: A sole trader is personally responsible for business debts. In a company limited by shares, shareholders are generally liable only for amounts unpaid on their shares. However, directors can still become personally liable in certain circumstances, including where they give a personal guarantee.^[1]

Tax: A sole trader pays Income Tax on taxable profits and may pay Class 4 National Insurance. Class 2 contributions are generally treated as paid once profits reach the relevant threshold, while voluntary contributions may be available below it. A limited company pays Corporation Tax, and money taken out as salary or dividends may create separate personal tax liabilities.^[2]

Administration: Sole traders generally have simpler reporting requirements, although Making Tax Digital for Income Tax now applies to some sole traders, depending on their income and eligibility.^[3]

Limited companies have additional duties, including keeping company records, filing annual accounts, submitting Corporation Tax returns and filing a confirmation statement with Companies House.^[3]

A director does not automatically need to complete a personal Self Assessment tax return simply because they are a director. Whether one is needed depends on their income and tax circumstances.^[3]

There is no simple rule that a limited company is always more tax-efficient. The result depends on profits, how money is withdrawn and your wider circumstances.

Our Conclusion

Being a sole trader is generally simpler, while a limited company provides legal separation but brings additional responsibilities. Choose based on liability, tax, administration and how you want to run your business.
