Sole Trader Handbook
Being a sole trader is the simplest way to run a business in the UK. But simple doesn't mean there's nothing to learn. This handbook covers everything you need to know — from registration and tax to invoicing, expenses and insurance — so you can run your business correctly and with confidence.
A sole trader is the simplest form of business in the UK. You're self-employed, you run the business yourself, and you keep all the profits after tax. There's no legal separation between you and your business — you are the business.
This simplicity is the main advantage. There's minimal paperwork to set up, no requirement to file accounts with Companies House, and you have complete control over how you run things. For many freelancers, tradespeople and small business owners, it's the right structure for the long term.
The main disadvantage is unlimited personal liability. If your business incurs debts or is sued, your personal assets — including your home — could be at risk. This is why insurance is particularly important for sole traders.
You can trade under your own name or a business name. If you use a business name, it must not include "Limited", "Ltd", "PLC" or similar terms, and it must not be offensive or misleading. You don't need to register a business name — but you should check it's not already trademarked.
Good to know
- You can be a sole trader and still have employees — the structure refers to ownership, not headcount
- You can change from sole trader to limited company at any time — it's not a permanent decision
- A business name is optional — many sole traders trade under their own name
- Sole trader status doesn't affect your ability to open a business bank account
Watch out for
- Confusing sole trader with self-employed — they're related but not identical terms
- Assuming you can't grow a significant business as a sole trader — many do
- Not understanding the personal liability implications before taking on large contracts
- Using "Ltd" in your business name — it's illegal unless you're incorporated
