If you start working for yourself, you’re classed as a self-employed sole trader - even if you’ve not yet told HM Revenue and Customs (HMRC).
As a sole trader, you run your own business as an individual. You can keep all your business’s profits after you’ve paid tax on them.
You can employ staff. ‘Sole trader’ means you’re responsible for the business, not that you have to work alone.
You’re personally responsible for any losses your business makes.
