Sole trader vs limited company: a comprehensive guide

Choosing between working as a sole trader and setting up a limited company is one of the first big decisions you make when starting or growing a business. It affects how you pay tax, how much admin you deal with, how your income is taken, and how much personal risk you carry.

There is no single right answer. A simple freelance business may work perfectly well as a sole trader. A growing business with higher profits, commercial contracts, staff, or financial risk may be better suited to a limited company.

At FHP Accounting, we regularly help business owners make this decision properly, rather than guessing and hoping it works out later.

What is a sole trader?

A sole trader is the simplest way to run a business in the UK. You trade as yourself, keep business records, report your profit through Self Assessment, and pay tax on the profit you make.

You do not need to register a company with Companies House. You usually need to tell HMRC that you are self-employed by 5 October after the end of the tax year in which you started trading.

This structure is popular because it is straightforward. If you are testing an idea, doing freelance work, earning from a side business, or keeping things small, it can be a sensible place to begin.

You still need proper records, though. Good bookkeeping services help you track income, expenses, profit and tax, so you are not trying to piece everything together just before the 31 January Self Assessment deadline.

What is a limited company?

A limited company is a separate legal entity. That means the company is legally separate from you as an individual. The company owns its money, enters into contracts, pays Corporation Tax, and files accounts.

You can be a director and shareholder of your own company. You may take money through salary, dividends, or a mix of both, depending on what is suitable for your position.

A company gives you more structure, but it also brings more responsibility. You need to file company accounts, a Company Tax Return, a confirmation statement and maintain proper statutory records. Directors and people with significant control also need to deal with Companies House identity verification requirements.

This is where support with company secretarial services and annual statutory accounts can make life much easier.

Sole trader vs limited company: the main differences

Tax as a sole trader

As a sole trader, your business profit is treated as your personal income. You pay Income Tax on your taxable profit after allowable expenses. For 2026/27, the Personal Allowance remains £12,570, although this can reduce if your income is high.

You also pay Class 4 National Insurance on self-employed profits above the relevant threshold. For many sole traders, this makes tax fairly easy to understand, but it can still become expensive as profits rise.

You report everything through a Self Assessment tax return. If this is not something you want to handle yourself, personal tax returns support can help keep the process accurate and on time.

A sole trader can still register for VAT, employ staff, use software, and run a serious business. The structure is simple, but that does not mean the business has to stay small.

Tax as a limited company

A limited company pays Corporation Tax on its profits. For 2026, the small profits rate is 19% for companies with profits up to £50,000, while the main rate is 25% for profits above £250,000. Companies with profits between these levels may fall into marginal relief.

You then pay personal tax when you take money out of the company. This may include salary through PAYE and dividends from post-tax profits. From April 2026, dividend tax rates are 10.75% for basic rate taxpayers, 35.75% for higher rate taxpayers and 39.35% for additional rate taxpayers. The dividend allowance remains £500.

This can still be efficient in some cases, but it is not automatically better for everyone. The right answer depends on your profit, other income, pension plans, cash needs, family position and future business plans.

If you are already trading through a company, company tax returns support can help you deal with HMRC filings and keep your Corporation Tax position clear.

When a sole trader structure may work best

A sole trader structure may suit you if:

• You are testing a business idea and want to keep costs low.
• You have modest profits and limited business risk.
• You do not need outside investment.
• You prefer simple admin and fewer filing requirements.
• You want to keep your financial information more private.

For example, if you are a freelance designer earning £35,000 a year with low overheads and no staff, a sole trader setup may be perfectly suitable. You still need to keep receipts, track your income, and claim allowable expenses properly, but the structure itself is simple.

If you are just starting out, business start-up accountants can help you set up the basics correctly from the beginning.

When a limited company may work best

A limited company may be more suitable if:

• Your profits are increasing.
• You want more legal separation between you and the business.
• You work with clients who prefer limited companies.
• You plan to employ staff.
• You want to retain profits in the company for future growth.
• You may need funding, contracts, or a more formal structure.

For example, if your consultancy is earning £120,000 a year, you have regular subcontractors, and you want to build a larger business, a limited company may give you more structure and flexibility.

You will need stronger systems. This may include Xero bookkeeping, payroll, VAT support and regular management information.

What about VAT?

VAT is separate from your business structure. Sole traders and limited companies both need to register for VAT if taxable turnover goes over the UK VAT threshold, which is £90,000 in a rolling 12-month period.

This catches many growing businesses out because it is not based on your accounting year. You need to monitor turnover month by month.

Once you register, you may need to charge VAT, file VAT returns and keep digital records. VAT return services can help you manage this properly, especially if your business has mixed income, property activity, or more complex expenses.

What about payroll?

If you run a limited company and take a director’s salary, you may need a PAYE scheme. If you employ staff, payroll becomes even more important.

You need to process wages correctly, deal with tax and National Insurance, manage pension duties and meet reporting deadlines. Payroll services can help reduce the risk of mistakes, especially when your team starts to grow.

Sole traders can also employ people, but again, the admin needs to be handled properly.

Should you switch from sole trader to limited company?

Many businesses start as sole traders and incorporate later. That is normal. The key is not to wait until the decision becomes rushed.

You may want to review your structure when profits rise, you take on bigger contracts, your risk increases, or you want to separate business and personal finances more clearly.

Before switching, think about:

• Tax savings after extra accountancy costs.
• Whether you need limited liability.
• How much profit you want to leave in the business.
• Whether clients or lenders expect a company structure.
• The extra admin you are willing to manage.

An outsourced finance department can also be useful if your business has grown beyond basic bookkeeping but you are not ready to hire an in-house finance team.

Which option is right for you?

If you want simplicity, low admin and flexibility, being a sole trader may be the better fit. If you want structure, legal separation and a more scalable setup, a limited company may make more sense.

The decision should not be based only on tax. It should also reflect risk, income, cash flow, commercial goals and how much admin you are prepared to take on.
