What is the difference between a freelancer and a contractor?

The terms are often used interchangeably, but contractors typically work on longer-term projects for one client at a time (often through a limited company), while freelancers tend to juggle multiple clients simultaneously on shorter projects. Contractors are more common in IT, engineering, and finance; freelancers in creative industries.

Is a sole trader the same as a freelancer?

Sole trader is a legal structure — how you're registered for tax. Freelancer is a working style. A freelancer can be a sole trader (most common) or operate through a limited company. You can be a sole trader without being a freelancer (e.g., running a shop).

Should I be a sole trader or limited company as a freelancer?

Sole trader is simpler and fine if you earn under £50,000 or want minimal admin. Limited company becomes more tax-efficient around £40,000+ profit, but involves more admin, accounting costs, and responsibilities. Consider your income level, liability concerns, and comfort with paperwork.

Do contractors have to use a limited company?

No, but many do for tax efficiency, especially at higher day rates. However, IR35 rules mean if you'd be an employee without your company, you can't benefit from limited company tax advantages. Some contractors use umbrella companies instead.
