Sole Trader vs Limited Company UK 2026: Which Is Better?

Choosing between sole trader vs limited company is one of the first big decisions you make in business — and one of the most common questions we are asked. The right answer is not the same for everyone: it depends on your profits, how much risk you are exposed to, whether you want to leave money in the business, and how much admin you are willing to take on.

This guide explains both structures in plain English, compares them across tax, liability, admin, cost and privacy, and walks through a worked example so you can see roughly how the numbers stack up. Tax rates change, so always check GOV.UK for current rates before making a final decision.

What is a sole trader?

A sole trader is the simplest way to run a business in the UK. You and the business are legally the same person. You register for Self Assessment with HMRC, keep records of your income and expenses, and report your profits each year on a tax return.

There is no separate legal entity — the profit is your income. You pay income tax on your profits, plus Class 4 National Insurance (and, above a small threshold, Class 2 contributions count towards your State Pension). Setting up is quick, cheap and lightly regulated, which is why so many freelancers, contractors and small businesses start this way.

The trade-off is that you have unlimited personal liability. If the business owes money it cannot pay, your personal assets — savings, and potentially your home — can be at risk.

What is a limited company?

A limited company is a separate legal entity that you register at Companies House. The company owns its assets, earns its own profits and is responsible for its own debts. You typically act as both a director (running it) and a shareholder (owning it).

The company pays corporation tax on its profits. You then decide how to pay yourself — usually a combination of a modest salary and dividends — and you pay personal tax on what you take out. Money you do not draw can stay in the company.

The headline benefit is limited liability: if the business fails, you generally only lose what you have put in, not your personal wealth (there are exceptions, such as personal guarantees or wrongful trading). The trade-offs are more admin, more cost and far less privacy. Our limited company setup service handles the formation so it is done correctly from day one.

How is each one taxed?

This is usually the deciding factor, so it is worth understanding clearly.

Sole trader. You pay income tax on your profits at the usual rates (basic, higher and additional), after your personal allowance. On top of that you pay Class 4 National Insurance on profits above a threshold. There is no separation between business and personal money — all the profit is taxed as your income whether you spend it or not.

Limited company. The company pays corporation tax on its profits. As a rough guide, the small profits rate is 19% on profits up to £50,000 and the main rate is 25% on profits over £250,000, with marginal relief tapering the effective rate between those points. After corporation tax, you extract money as salary and dividends and pay personal tax on those. Dividends have their own (lower) tax rates and a small tax-free dividend allowance.

The efficiency of a company comes from two things: dividends are taxed more lightly than salary, and you can retain profit in the company rather than drawing it all and being taxed on it personally. Always confirm the current corporation tax, dividend and National Insurance rates on GOV.UK, as they change frequently.

Sole trader vs limited company: side-by-side

Factor	Sole trader	Limited company
Tax	Income tax + Class 4 NIC on all profits via Self Assessment	Corporation tax on profits; personal tax on salary and dividends drawn
Liability	Unlimited — personal assets at risk	Limited to what you invest (with some exceptions)
Admin	Light — one Self Assessment return a year	Heavier — annual accounts, corporation tax return, confirmation statement, payroll
Privacy	Your details stay private	Company and director details and accounts are public on Companies House
Cost	Low — minimal setup and accountancy fees	Higher — formation, filing and usually higher accountancy fees
Raising finance	Harder — borrow personally; cannot sell shares	Easier — can issue shares and may look more credible to lenders

Liability: who is on the hook?

For many owners this matters as much as tax. As a sole trader, there is no legal shield between you and the business — a bad debt, a contract dispute or a claim can reach your personal assets.

A limited company ring-fences that risk. Because the company is a separate person in law, creditors normally pursue the company, not you. This protection is not absolute: directors who give personal guarantees, trade while insolvent or behave improperly can still be liable. But for businesses carrying real financial or legal risk — holding stock, employing staff, signing large contracts — limited liability is a strong argument for incorporating.

Admin and cost

A sole trader’s obligations are light: keep good records and file one Self Assessment return a year. That is it.

A limited company carries more:

• File annual accounts at Companies House.
• File a corporation tax return (CT600) with HMRC.
• File an annual confirmation statement.
• Maintain statutory registers and records.
• Run payroll if you take a salary.
• File your own Self Assessment as a director drawing dividends.

This extra work usually means higher accountancy fees, which is exactly why incorporating rarely pays at low profit levels — the tax saving can be swallowed by the cost of compliance. We cover this in detail in our guide to limited company setup costs.

Privacy

A sole trader keeps their financial affairs private. A limited company is on the public record: anyone can look up your company, its registered office, its directors and (in summarised form) its accounts on the Companies House register. For some owners that transparency is fine — even helpful for credibility — but if privacy matters to you, it is a genuine downside of incorporating.

Raising finance and credibility

If you plan to bring in investment or scale quickly, a limited company is usually the better vehicle. You can issue shares to investors, which a sole trader simply cannot do. Some clients, agencies and lenders also prefer — or require — dealing with a limited company. A sole trader can still borrow, but only personally, against their own standing.

A simplified worked example at £60,000 profit

Imagine a business making £60,000 profit a year. Here is an illustrative, simplified comparison of the two structures. The exact figures depend on current rates and on how much you draw, so treat this as a guide only, not a calculation for your situation.

SOLE TRADER (£60,000 profit)
Income tax (basic + higher rate on the slice over the
higher-rate threshold, after personal allowance)
Plus Class 4 National Insurance on profits over the threshold
= a meaningful chunk of the £60,000 taken in tax and NIC,
  and every pound of profit is taxed whether you spend it or not

LIMITED COMPANY (£60,000 profit)
Step 1: Company pays corporation tax (~19% small profits rate)
Step 2: You take a small salary + dividends from what remains
Step 3: You pay personal tax on the dividends (lower dividend rates)
Step 4: Any profit you DON'T draw stays in the company,
        taxed only at corporation tax — not at your marginal rate

In broad terms, the company route tends to leave more in your pocket once profits reach the £30,000–£50,000+ range, particularly if you can avoid drawing all the profit. Below that, the extra admin and accountancy cost often cancels out the saving. This is exactly why a quick projection on your own numbers — not a rule of thumb — should drive the decision.

When should you switch from sole trader to limited company?

There is no single magic number, but useful signals to consider incorporating include:

• Profits consistently above ~£30,000–£50,000, especially if you do not need to draw all of it.
• Rising risk — bigger contracts, employees, stock or borrowing — where limited liability matters.
• Clients or lenders who prefer or require a limited company.
• Plans to raise investment or eventually sell the business.

Switching is straightforward: register a company, transfer the trade and assets, tell HMRC, and file a final sole trader Self Assessment. You can explore the options on our business formation hub, and GOV.UK sets out the official steps to set up a limited company.

So, sole trader or limited company?

There is no universal winner. As a rough summary:

• Stay a sole trader if profits are modest, risk is low and you value simplicity, low cost and privacy.
• Go limited if profits are higher, you want liability protection, you can leave money in the business, or you are scaling and may raise finance.

The smartest move is to run the actual numbers for your situation and weigh the tax saving against the extra admin and lost privacy. Rates and thresholds change, so always confirm the current figures on GOV.UK before you commit.
