Sole trader
Simplest UK self-employed business structure. The individual and the business are legally the same entity — unlimited personal liability but minimal admin.
Becoming a sole trader is the easiest way to start freelancing in the UK — you simply register for self-assessment with HMRC. There's no separate legal entity: business profits are personal income, taxed via your annual self-assessment tax return.
The main advantage is simplicity: no Companies House filings, lower accounting costs, full control over the business. The main downside is unlimited personal liability — if the business owes money, your personal assets are at risk.
Many freelancers start as sole traders and incorporate to a limited company once their income passes around £30-50k annually, where the tax savings begin to outweigh the added admin.
- Quick to set up: register online with HMRC for self-assessment
