Sole trader vs limited company for tradespeople
It's the question every self-employed tradesperson hits sooner or later: should I stay a sole trader, or set up a limited company? There's a lot of pub-talk about it ("go Ltd, you'll save a fortune") and most of it is half right at best. The honest answer depends on your profit, your risk, and how much admin you can stomach.
Here's the plain-English version. The specific tax figures below move most years — treat them as the shape of the decision and confirm the current numbers (or ask an accountant) before you act.
Sole trader: simple, personal, exposed
As a sole trader, you are the business. You keep the profits, you file a Self Assessment tax return, and it's about as simple as running a business gets.
Tax: you pay Income Tax on your profits (after the personal allowance), plus National Insurance for the self-employed. The rules on the self-employed NI classes have changed recently — the important point is you pay NI on your profits, and the exact mechanics are worth checking for the current year.
Pros:
- Dead simple to set up and run.
- Minimal admin — one tax return a year.
- Your finances are private (nothing on public record).
- Easy to change your mind and incorporate later.
The big catch — unlimited liability. There's no legal line between you and the business. If the business owes money it can't pay, that's your money, your house, your savings. For a lot of trades that risk is manageable with good insurance — but it's real.
Limited company: separate, protected, more paperwork
A limited company is its own legal "person." The business's debts are the company's, not yours (barring fraud or personal guarantees) — that's limited liability, and it's the headline reason people incorporate.
Tax: the company pays Corporation Tax on its profits (a 19% small-profits rate up to £50,000, rising toward 25% on higher profits, with marginal relief in between — check current rates). You then pay yourself, usually as a mix of a small salary and dividends, and dividends are taxed at lower rates than wages — which is where the tax saving comes from. Note the dividend allowance has been cut hard in recent years (down to a few hundred pounds — check the current figure).
Pros:
- Limited liability — your personal assets are protected.
- Often more tax-efficient at higher profits (the salary-plus-dividends split).
- Can look more credible to bigger clients and main contractors.
- Easier to bring in a partner or sell later.
Cons:
- More admin and cost — annual accounts, a Corporation Tax return, a confirmation statement to Companies House, usually an accountant (budget for their fee).
- Public record — your company details and accounts are visible on Companies House.
- Money isn't "yours" — you can't just take cash from the account; you pay yourself properly through salary/dividends.
- IR35 can bite if you effectively work like an employee for a single client through your company — mainly a concern for labour-only subbies with one main contractor.
Roughly where a limited company starts to pay
There's no magic number, but as a rough guide the tax advantages of a limited company tend to start outweighing the extra admin somewhere around £40,000–£50,000 of annual profit — and even then it depends on how much you need to draw out to live on versus leave in the company. Below that, the sole-trader simplicity often wins; well above it, Ltd usually pulls ahead.
That threshold is a rule of thumb, not a promise — it shifts with tax rates and your personal situation. This is exactly the sum an accountant will do for you in ten minutes with your real numbers.
It's not only about tax
Don't let the tax tail wag the dog. Non-tax reasons matter too:
- Liability. If your work carries real financial risk (big commercial jobs, expensive properties), the limited-liability protection can be worth it on its own.
- Credibility. Some commercial clients and contractors prefer — or only deal with — limited companies.
- CIS gross payment status. Established companies can apply for gross payment status so contractors pay them without the CIS deduction — a cashflow win for subbies.
- Simplicity. For a lot of one-person domestic trades, staying a sole trader and sleeping easy is a perfectly good answer.
Quick comparison
| Sole trader | Limited company | |
|---|---|---|
| Set-up | Register with HMRC, done | Incorporate at Companies House |
| Liability | Unlimited (personal) | Limited to the company |
| Main tax | Income Tax + NI on profit | Corporation Tax + tax on salary/dividends |
| Admin | One tax return a year | Accounts, CT return, confirmation statement |
| Privacy | Private | On public record |
| Best when | Lower profit, simple, low risk | Higher profit, more risk, want protection |
The practical answer
Most tradespeople start as a sole trader — it's simple, cheap and reversible — and switch to a limited company once profits climb past the point where the tax saving covers the extra hassle, or once liability starts to worry them. If you're just getting going, don't overthink it; the first 90 days matter more than the structure.
And whichever you pick: get an accountant. For a few hundred quid a year they'll save you more than they cost, run the sole-trader-vs-Ltd sum on your actual numbers, and keep you the right side of HMRC.
