Self-Employed vs Sole Trader: What’s the Difference?
Quick answer
This confuses almost everyone, and it doesn’t help that HMRC uses both terms interchangeably in places. Here’s the actual distinction. For more on getting set up, see our complete getting started guide.
The short version
Self-employed is a tax status. It means you work for yourself and pay your own tax, rather than having an employer deduct it from your wages.
Sole trader is a business structure. It’s the simplest way to be self-employed — you run a business as an individual, with no legal separation between you and the business.
All sole traders are self-employed. But not all self-employed people are sole traders — some run partnerships or limited companies.
Why it matters
When you register with HMRC, you register for Self Assessment as a sole trader. That’s the specific box you tick. HMRC then treats you as self-employed for tax purposes.
In everyday conversation, “self-employed” and “sole trader” mean the same thing for most people. If you’re a freelancer, contractor, tradesperson, or small business owner working on your own without a limited company, you’re a sole trader.
The three ways to be self-employed
| Structure | What it means | Liability | Tax |
|---|---|---|---|
| Sole trader | You and the business are one entity. Simplest setup. | Unlimited — your personal assets are at risk | Income Tax + NI on profits via Self Assessment |
| Partnership | Two or more people share a business. Each partner is self-employed. | Unlimited (each partner) | Each partner pays Income Tax + NI on their share |
| Limited company director | The business is a separate legal entity. You’re technically employed by your own company. | Limited to company assets | Corporation Tax on profits, Income Tax on salary/dividends |
For most people starting out, sole trader is the right choice. It takes 10 minutes to register, costs nothing, and your bookkeeping obligations are straightforward. You can always switch to a limited company later if your business grows and the tax savings justify the extra admin.
What about freelancers and contractors?
“Freelancer” and “contractor” aren’t legal terms — they’re descriptions of how you work. Most freelancers and contractors are sole traders unless they’ve set up a limited company (common in IT contracting for IR35 reasons, less common elsewhere).
If you call yourself a freelancer and you haven’t incorporated a company, you’re a sole trader. Same rules, same registration, same tax.
Common misconceptions
“I need to register a business to be a sole trader” No. You register with HMRC for Self Assessment. There’s no Companies House registration, no business registration fee, and no formal paperwork beyond the HMRC form. You can register in about 10 minutes.
“Sole traders can’t hire people” Wrong. Sole traders can employ staff. You’d need to register as an employer with HMRC and run PAYE, but the business structure doesn’t prevent it.
“Being self-employed means I don’t pay National Insurance” You pay two types: Class 2 (£3.45/week, flat rate) and Class 4 (6% on profits between £12,570 and £50,270, 2% above that). These are calculated as part of your Self Assessment tax return. More detail in our National Insurance guide.
“I need to register a business name” Not as a sole trader. You can trade under your own name or choose a trading name — no registration required. Just follow the naming rules.
