Sole trader vs limited company: which is right for a fitness instructor?
The practical differences between operating as a sole trader and a limited company for UK yoga, Pilates and personal training instructors.
Most freelance instructors start as a sole trader — it's simple, cheap and quick. As earnings grow, the question of whether to incorporate as a limited company comes up. Here's an honest comparison.
Sole trader: pros and cons
As a sole trader you and the business are the same legal entity. Set-up is free, admin is light (one Self Assessment return a year), and you can withdraw money whenever you like. The downsides: unlimited personal liability, and once profits pass roughly £50,000 your marginal tax rate jumps.
Limited company: pros and cons
A limited company is a separate legal entity. It pays 19–25% Corporation Tax on profits, and you pay yourself through a mix of salary and dividends. That can be tax-efficient once profits pass around £30,000–£50,000, and it gives you limited liability. The trade-off is more admin: annual accounts, a confirmation statement, PAYE if you take a salary, and usually an accountant.
Rough guide by profit level
- Under £30,000 profit: sole trader is almost always simpler and cheaper
- £30,000–£50,000: worth doing the maths — savings are modest
- Over £50,000: incorporation often saves meaningful tax
Numbers aren't the only factor. If you teach corporate clients or larger studios, some prefer to contract with a limited company for their own IR35 comfort. If you value simplicity above all, sole trader wins hands down.
