This is a directional quiz, not legal or tax advice — it weighs your answers against the trade-offs that matter most (liability, tax efficiency, admin, and investment plans) but doesn't know your exact numbers. If profit or liability sits near a threshold, or you're weighing sole trader against limited company specifically, run the numbers through our sole trader vs limited company calculator below before registering anything. Ordinary partnerships and LLPs both need a partnership/LLP agreement drawn up properly — a solicitor or accountant is worth it here.
Choosing between a sole trader, partnership, limited company, or LLP is usually the first real decision anyone starting a UK business has to make, and most guides just list the four options without helping you weigh them against your actual situation. The right structure depends on how much personal liability protection you want, how many people are involved, what kind of profit you're expecting, whether you'll ever want investors, and how much admin you're willing to take on — this quiz scores all five factors against each structure and shows you which one is the closest fit, along with how the runners-up compare.
It's a starting point rather than a final answer. Structures can be changed later — plenty of sole traders incorporate once profit grows — so getting close enough to start is usually more valuable than agonising over a perfect answer up front.
As a sole trader, you and the business are legally the same thing — you keep all the profit after tax, but you're personally liable for business debts. A limited company is a separate legal entity: it owns the profit, pays corporation tax, and you're paid out of it as salary or dividends, with your personal liability generally limited to what you've invested. The company route usually means more admin — annual accounts, a confirmation statement, and Companies House filings.
Functionally, close to it. An ordinary business partnership splits profit and liability between partners, but each partner is personally liable for the whole partnership's debts, not just their own share — including debts run up by a partner they don't control. An LLP (Limited Liability Partnership) fixes that by giving partners the same kind of liability protection a limited company gives shareholders, at the cost of more admin than an ordinary partnership.
Yes — moving from sole trader to limited company is common and reasonably straightforward once profit grows, since incorporation is usually more tax-efficient above a certain point. Going the other way (company back to sole trader) is rarer and more involved, since it means formally closing the company down. Starting simple and incorporating later is a completely normal path.
