“It’s one of the most common questions we hear, and one of the most casually answered. “Should I be a limited company?” The truthful answer is that it depends, but it depends on specific things, not on a feeling. So let’s walk through the actual decision.
By the end of this you’ll know which one fits your situation right now, and what would change the answer.
The short version: what’s the difference?
A sole trader is you, trading as yourself. There’s no legal separation between you and the business. You keep all the profit, and you’re personally responsible for any debt.
A limited company is a separate legal entity, owned by shareholders (often just you) and run by directors (often just you again). The business owns the profit, you decide how to take it out, and the company is liable for its own debts, not you personally.
Same work, very different structure. The right one depends on five things.
Five questions to actually decide
1. What’s your profit, not turnover?
This is the biggest single factor and the one people get wrong most often. Sole trader tax is straightforward at low profits and stops being so at higher ones. As a rough rule, once your profit reliably climbs above £50,000 a year, the tax efficiency of a limited company starts to outweigh the extra admin. Below that, it usually doesn’t.
Note that’s profit, not turnover. Turning over £80,000 but only profiting £25,000 isn’t the same conversation as turning over £80,000 and profiting £60,000.
2. Do you need flexibility in how you take money out?
As a sole trader, your business income is your personal income. There’s no separation, no decision to make about it.
As a limited company director, you can take money out as salary, dividends, pension contributions, or leave it in the business to invest or save tax. That flexibility is one of the biggest practical benefits of going limited, especially as profit grows.
3. How much risk does your work carry?
If your work could realistically lead to being sued (anything involving advice, professional services, or significant client relationships), the limited liability of a company is genuinely valuable. Your personal assets sit behind a legal wall.
If your risk is low (a freelance designer, a small online seller, a side income), liability protection matters less, and the admin of being limited may not be worth it for that reason alone.
4. Are you comfortable with your accounts being public?
Limited companies file accounts with Companies House, and they’re public. Anyone can look up your accounts, see your filing history, and see who the directors and shareholders are.
Sole trader figures are private. HMRC sees them, nobody else does.
For some people this is irrelevant. For others (particularly in competitive industries), it’s a real consideration.
5. How much admin can you stomach?
Sole trader admin is light. One annual Self Assessment tax return, basic record-keeping, and that’s most of it.
Limited company admin is heavier. Annual accounts, Corporation Tax return, Confirmation Statement, dividend records, payroll if you take a salary. Most directors outsource this to an accountant precisely because it’s enough to be a job in itself.
So which one’s right for you?
If your profit is comfortably under £50,000, your work is low-risk, and you prefer simplicity, sole trader is probably the right call.
If your profit is climbing past £50,000, you want flexibility in how you take money out, your work carries real risk, and you’re comfortable with the admin (or willing to pay someone to handle it), going limited is usually worth it.
And if you’re sitting in the middle and genuinely not sure, that’s exactly the conversation a good accountant should be having with you, with your real numbers in front of you, not as a generic recommendation.
When the answer changes
The right structure now isn’t necessarily the right structure forever. Profit climbing past the threshold, taking on staff, doing more high-value contracts, or simply wanting to start saving for retirement through pension contributions, all of these can shift the answer.
It’s worth reviewing the question every couple of years, particularly if your business has grown. The tax difference between the two structures can be substantial at higher profit levels, and “we just always did it this way” isn’t a good answer.
