Should I operate as a sole trader or limited company in the UK?

Both structures have pros and cons, and the right choice depends on your income level, risk appetite, and personal circumstances. Sole trader advantages: simpler and cheaper to set up and run, minimal reporting requirements, you pay Income Tax and Class 4 NI on profits, no separate company tax return. Limited company advantages: potentially lower overall tax at higher income levels (Corporation Tax is 19–25% vs up to 45% Income Tax), limited personal liability, ability to retain profits in the company, more options for pension contributions and tax planning. The tax efficiency crossover point is typically around £30,000–£40,000 of profit, above which a limited company often saves tax — though this depends heavily on dividends vs salary decisions, accountancy costs, and your individual situation. For most sole traders earning under £30,000, the simplicity of sole trader status usually outweighs the potential tax savings of incorporating. Always take personalised advice from an accountant before incorporating.
