Should you start your contractor business as a sole trader or a company?

In a nutshell, sole trader structures are cheap and easy to set up but are riskier as the owner will be personally liable for the business. Companies are slightly more expensive but offer better protection, less risk and more flexibility in terms of tax purposes. If you intend on growth, a company structure may be more ideal for you.
