Self-Employment Guides UK — Tax, Business Setup, and Running Your Own Business

Self-Employment — The Complete UK Guide (2026)

Everything you need to know about being self-employed in the UK. From registering as a sole trader or forming a limited company, to tax, expenses, IR35, invoicing, and financial planning.

Self-employment tax and business information is based on current HMRC rules. This is not tax or accounting advice. Consider consulting a qualified accountant for your specific circumstances.

Self-employment is a way of life for over 4 million people in the UK — from freelancers and contractors to sole traders running established businesses. Whether you’re just starting out, deciding between a sole trader and limited company structure, or managing the complexities of IR35, tax returns, and business expenses, the self-employment landscape has its own set of rules that differ significantly from employment.

The financial rewards of self-employment can be substantial: the ability to set your own rates, choose your clients, claim legitimate business expenses against tax, and structure your income tax-efficiently. But with those rewards come responsibilities — filing Self Assessment tax returns, paying National Insurance contributions, managing cash flow, and planning for periods without income.

Understanding your obligations and rights as a self-employed person is essential from day one. Getting your business structure right, keeping accurate records, claiming all allowable expenses, and planning for tax bills can make the difference between self-employment that thrives and self-employment that struggles.
