Sole Trader vs Limited Company: Which Structure Is Right for Your Business?

Choosing whether to operate as a sole trader or through a limited company is one of the first decisions many business owners face.

There isn’t one structure that is right for everybody. Your choice can affect how you pay tax, your legal responsibilities, how you take money from the business and the amount of administration involved.

It also isn’t necessarily a permanent decision. Many businesses start as sole traders and incorporate later as the business develops.

This guide explains some of the main differences.

What is a sole trader?

A sole trader is somebody who runs a business as a self-employed individual.

It is generally the simplest of the two structures. You own the business personally, make the business decisions and keep its profits after tax.

However, there is no separate legal entity between you and the business. As a sole trader, you have unlimited liability, which means you are personally responsible for the debts of the business.

You will normally report your business income and expenses to HMRC through Self Assessment and pay tax personally on the resulting taxable profit.

What is a limited company?

A limited company is legally separate from the people who own it.

The company can enter into contracts, own assets, owe money and make profits in its own right. The company is run by one or more directors and owned by its shareholders. In a small owner-managed business, the same person will often be both a director and shareholder.

This separation is one of the biggest differences compared with being a sole trader.

Generally, shareholders’ liability for the company’s debts is limited to their financial investment in the company, although limited liability should not be confused with complete protection from every possible personal liability.

What are the main differences?

The right structure depends on much more than one row of this table.

How is a sole trader taxed?

As a sole trader, you are generally taxed personally on the taxable profits of the business.

This means it is the profit, rather than simply the amount of money you withdraw from the business, that matters for Income Tax purposes.

For 2026/27, the standard Personal Allowance is £12,570, although it can be reduced where adjusted net income exceeds £100,000. For England, Wales and Northern Ireland, the main Income Tax rates remain 20%, 40% and 45%, subject to the applicable bands and the individual’s circumstances.

Self-employed individuals may also pay Class 4 National Insurance. For 2026/27, this is generally 6% on profits between £12,570 and £50,270 and 2% above £50,270.

Important

Taking less money out of a sole-trader business does not normally reduce the profit on which you are taxed. The business profit belongs to you personally whether you leave the cash in the business bank account or withdraw it.

How is a limited company taxed?

A limited company pays Corporation Tax on its taxable profits.

For the financial year beginning 1 April 2026, the small profits rate is 19% for qualifying profits up to £50,000 and the main rate is 25% where profits exceed £250,000. Marginal relief applies between the two thresholds.

Those thresholds can be reduced, including where the company has associated companies or a short accounting period.

But Corporation Tax is only one part of the picture.

The company’s money does not automatically belong to its director or shareholders personally. There are rules governing how money is taken from a company.

How do I pay myself from a limited company?

Owner-directors commonly take money from their company through a combination of methods such as salary and dividends.

A salary is normally processed through payroll and may result in PAYE Income Tax and National Insurance depending on the amount and circumstances.

Dividends are different. They can only be paid from profits available for distribution and must follow the relevant company-law requirements.

For 2026/27, the dividend allowance is £500. Dividend income above the available allowance is generally taxed at 10.75% within the basic-rate band, 35.75% within the higher-rate band and 39.35% within the additional-rate band.

Other methods of extracting value, including directors’ loans and certain benefits, have their own tax and reporting rules.

This is why comparing a sole trader’s Income Tax rate with a company’s Corporation Tax rate does not tell you which structure produces the lower overall tax bill.

Important

A 19% Corporation Tax rate does not mean a limited-company owner simply pays 19% tax personally. The tax position needs to consider both the company and how money or benefits are ultimately provided to the individual.

Is a limited company more tax efficient?

Sometimes it can be, but not always.

This is one of the biggest misconceptions when comparing the two structures.

Whether incorporation produces a tax advantage depends on factors including:

• The level of business profits
• How much money you need to withdraw personally
• Other income you receive
• Whether profits will be retained in the company
• Salary and dividend levels
• Pension contributions and other remuneration
• Whether the company has associated companies
• The additional costs of operating the company
• Your future plans for the business

Changes to tax rates can also alter the comparison from one year to the next.

For that reason, somebody considering incorporation should ideally compare the likely position using their own figures rather than relying on a generic online calculation.

What about limited liability?

Limited liability is an important non-tax difference.

A sole trader has unlimited liability for the debts of the business. If the business cannot meet its obligations, the owner can potentially be personally responsible.

A limited company is a separate legal entity and shareholders generally have limited liability.

However, operating through a limited company does not mean a director can never become personally liable. Circumstances such as personal guarantees or breaches of directors’ duties can change the position.

Business insurance may therefore still be important regardless of the structure chosen.

Is there more administration with a limited company?

Generally, yes.

A sole trader still needs proper accounting records and must meet their tax obligations, but a limited company has additional statutory responsibilities.

Company directors are legally responsible for matters including keeping appropriate records, preparing annual accounts, completing the company’s tax requirements and making the required filings. Companies must also file a confirmation statement at least once every 12 months.

There are also requirements to report certain changes to Companies House, including changes relating to directors and people with significant control.

An accountant can deal with many of the practical filing and accounting requirements, but appointing an accountant does not remove the director’s underlying legal responsibilities.

What information about a limited company is public?

A limited company has greater public reporting requirements than a sole trader.

Companies House holds information about registered companies, and certain information about directors is publicly available. Annual accounts are also filed with Companies House.

That is worth considering if privacy is particularly important to you.

There have also been significant changes to Companies House identity verification. Directors now need to verify their identity and provide their Companies House personal code at the appropriate point. New company registrations require the personal code for each director as part of the registration process.

Does being a limited company look more professional?

Some customers, suppliers, lenders or organisations may prefer dealing with a limited company, and in some industries the structure may be commercially useful.

But becoming a limited company does not automatically make a business more established, successful or professional.

A well-run sole-trader business can be substantial and highly professional, while incorporation on its own says very little about the quality of a business.

The commercial expectations of your particular industry and customers are therefore more relevant than the letters “Ltd” after a name.

Can I start as a sole trader and become a limited company later?

Yes.

This is very common.

Starting as a sole trader can provide a relatively straightforward way to begin trading, and incorporation can be considered later if the business grows or circumstances change.

However, incorporation isn’t simply a matter of opening a company and carrying on exactly as before.

Assets, contracts, VAT, payroll, business bank accounts, existing debts and other matters may need to be considered when transferring an existing business to a company. There can also be tax implications depending on what is transferred and how the change is structured.

Professional advice before making the change can therefore be valuable.

Which structure should I choose?

There isn’t a universal answer.

A sole trader structure may appeal where simplicity and lower administration are priorities, particularly when starting a relatively straightforward business.

A limited company may become more attractive where limited liability, retaining profits within the business, ownership arrangements or other commercial and tax considerations are important.

But tax should not be considered in isolation.

The most appropriate structure depends on the business, the risks involved, expected profits, how much income the owner needs personally and their longer-term plans.

Important

Don’t incorporate a business purely because somebody has told you that “limited companies pay less tax”. The comparison should be based on your circumstances and the current tax rules.
