Sole Trader vs Limited Company

Starting a business is an exciting journey. Whether you are a freelancer, consultant, contractor or small business owner, there may come a time when you start asking yourself an important question: Should I continue as a sole trader, or is it time to incorporate my business?

This is a question I often encourage business owners to think about carefully. Incorporating a business can offer several advantages, including limited liability, opportunities for tax planning and a more formal business structure. However, it also comes with additional responsibilities, costs and compliance requirements.

One thing I have learnt is that incorporating a business is not simply about paying less tax. It is about understanding how you want your business to grow, how you intend to take money out of it and what responsibilities you are prepared to take on.

In this blog post, I will explain how to incorporate a business in the UK, the advantages and disadvantages of operating through a limited company, and some of the tax considerations you should understand for the 2026–27 tax year.

How do you incorporate a business in the UK?

Incorporating a business means registering it as a separate legal entity with Companies House. Once the company is registered, it exists independently of you as an individual.

Before you begin the registration process, there are a few important things to consider.

1. Choose a name for your company

One of the first decisions you will need to make is what to call your new company.

You may decide to keep the same name you have been using as a sole trader. However, you must check that the proposed company name is available and complies with Companies House naming rules.

If another company has already registered the name, you may need to choose a different one or make an appropriate change.

I would also recommend checking whether the name could infringe an existing trademark. A name being available at Companies House does not automatically mean you have the right to use it as a trademark.

2. Decide who will own and manage the company

You will need to decide who will be appointed as a director and who will own shares in the company.

You can establish a limited company on your own, or you may decide to involve business partners, family members or other investors.

If you have more than one shareholder, it is important to consider how many shares each person will own and what rights those shares will carry.

For example, if you and a business partner are starting a company together, you may decide to divide the shares equally. However, you should also consider what would happen if you disagreed about the direction of the business or one of you wanted to leave.

This is why I recommend thinking carefully about the ownership structure before incorporating.

You will also need to provide the required information about directors, shareholders and people with significant control.

3. Complete the registration with Companies House

Once you have made these decisions, you can register your company through the official Companies House service or use an accountant or company formation agent.

From 2026, identity verification requirements are an important part of the process. Directors and people with significant control may need to verify their identity and use their Companies House personal code as required.

Online incorporation currently costs £100, and registration is usually completed within 24 hours, although times can vary. Check the official service for the latest fees before applying.

You can start here: Register a limited company with Companies House.

After registration, you will receive a certificate of incorporation confirming that your company legally exists. It will include your company number and incorporation date.

You should keep this document safe, together with your memorandum and articles of association and records of share ownership.

You will also need to understand the difference between your Companies House authentication code, which is used for certain company filings, and your personal code for identity verification. They serve different purposes.

4. Understand your responsibilities to HMRC

Once your company is incorporated, you will need to understand its tax obligations.

Companies House registration normally sets up Corporation Tax registration at the same time, unless the company is dormant. HMRC will provide information about your company’s tax registration and obligations.

Keep your Corporation Tax Unique Taxpayer Reference (UTR) safe. You will need it when dealing with HMRC.

Depending on your circumstances, you may also need to register for PAYE if you employ staff or pay yourself a salary, register for VAT if required or voluntarily eligible, and submit a Company Tax Return.

Remember that incorporating your company is only the beginning. You must also keep accurate accounting records, prepare annual accounts and submit the necessary filings on time.

Advantages of incorporating your business

There are several reasons why business owners choose to operate through a limited company. Let us look at some of the main advantages.

1. Limited liability

One of the main advantages of a limited company is that it is legally separate from its owners.

In general, shareholders’ liability is limited to the amount they have agreed to invest or pay for their shares. This can help protect personal assets if the company experiences financial difficulties.

However, this protection is not absolute. Directors may still face personal liability in certain circumstances, including some guarantees, wrongful conduct or breaches of their legal duties.

For me, this is an important consideration for business owners who want to build a business with a clear legal structure.

2. Opportunities for tax planning

Tax planning is one of the reasons people consider incorporation, but it is important to look at the whole picture rather than focusing on one tax rate.

For the 2026–27 tax year, Corporation Tax rates are generally:

• 19% on taxable profits within the small profits rate, generally up to £50,000.
• 25% on taxable profits above £250,000.
• Marginal Relief may apply where profits fall between those limits.

These thresholds can be reduced where a company has associated companies or a short accounting period, and other rules may apply.

A sole trader, by comparison, pays Income Tax on taxable business profits, together with any applicable National Insurance contributions.

A limited company pays Corporation Tax on its taxable profits. The owner may then pay personal

tax when taking money out through salary, dividends or other taxable benefits.

This means incorporation can create planning opportunities, particularly if you do not need to withdraw all the profits from your business immediately. However, it does not automatically mean that you will pay less tax overall.

3. Paying yourself a salary as a director

When you operate through a limited company, you can be employed by your own company and receive a salary as a director.

A properly incurred salary is generally deductible when calculating the company’s taxable profits, subject to the usual rules.

For example, if your company pays you a salary of £12,000, that salary will generally be an allowable business expense. The company may therefore pay less Corporation Tax than it would have paid if the salary had not been incurred.

However, the actual tax saving depends on the company’s Corporation Tax position and any applicable restrictions. You should also consider PAYE, employee National Insurance and employer National Insurance.

For 2026–27, the employer National Insurance rate is generally 15% on earnings above the applicable secondary threshold, which is £5,000 a year for most employees. The Employment Allowance may reduce an eligible employer’s National Insurance bill, subject to the relevant conditions.

As a director, your own National Insurance is calculated using the special annual earnings method in most cases, although alternative arrangements may apply.

The right salary will depend on your circumstances, including whether you have another job, other sources of income, the company’s profits and whether the company qualifies for Employment Allowance.

This is why I would not recommend choosing a director’s salary based on a fixed figure without reviewing the wider tax position.

4. Flexibility in how you take money out of the company

As a sole trader, you can withdraw money from your business bank account for personal use. These drawings are not themselves an allowable business expense, and you pay tax on your business profits rather than on the amount you withdraw.

With a limited company, the position is different because the company’s money belongs to the company, not directly to you.

You may take money out through a salary, dividends, pension contributions or other legitimate arrangements, depending on the circumstances.

This can provide flexibility in planning your income. For example, if your company makes a profit that you do not immediately need for personal spending, you may be able to retain some of the money in the company for future investment.

However, retaining profits does not eliminate Corporation Tax, and the eventual tax treatment of withdrawals needs to be considered.

5. Company cars and other benefits

After incorporation, you may decide that your company should provide you with a car.

A company car can be useful, especially if you need a vehicle for business purposes. However, if the car is available for your private use, you will generally be taxed on the company car benefit.

The taxable benefit depends on factors such as the car’s list price, its CO₂ emissions and its fuel type. Different rules apply to electric, hybrid and petrol or diesel vehicles.

The company may also have to pay Class 1A National Insurance on the taxable benefit. For 2026–27, the general Class 1A rate is 15%.

A company car is not automatically more tax-efficient than owning a car personally. Before making a decision, I recommend comparing the full cost of providing the vehicle with the personal tax and National Insurance consequences.

6. Building a business for the future

Incorporation may also be useful if you plan to bring in investors, issue shares to business partners or eventually sell your business.

A limited company has a formal ownership structure, which can make it easier to document who owns what and how decisions are made.

Of course, whether incorporation is appropriate depends on your business model, growth plans and the expectations of any potential investors.

Disadvantages of incorporating your business

While there are advantages, I always encourage business owners to look at the disadvantages as well. Incorporation is not the right choice for everyone.

1. Increased accounting and compliance responsibilities

A limited company has more formal reporting obligations than a typical sole trader.

Depending on its circumstances, the company will need to prepare annual accounts, file a Company Tax Return, pay Corporation Tax, maintain statutory records and submit a confirmation statement to Companies House at least once a year.

If you pay yourself or employ staff, you may also need to operate PAYE and report payroll information to HMRC.

These responsibilities can increase the cost of running your business. You may need accounting software, professional accountancy support and additional time to keep your records up to date.

There can also be penalties if you miss filing deadlines.

For this reason, I suggest including the cost of compliance in your decision about whether to incorporate.

2. You must plan how to withdraw profits

One of the biggest differences between being a sole trader and operating through a limited company is the treatment of business money.

As a sole trader, the business is not a separate legal person from you. You can generally withdraw money as drawings without creating a separate salary or dividend transaction.

With a limited company, the money belongs to the company. You cannot simply treat the company bank account as your personal account.

You need to make sure that money taken out is recorded correctly and has an appropriate basis, such as salary, dividends, a repayment of money you previously lent the company or a properly documented loan.

Poor planning can result in unexpected tax liabilities and accounting complications.

3. Dividend tax rates have increased for 2026–27

Dividends are a common way for owner-directors to receive profits from their limited companies, but the tax rules have changed.

For the 2026–27 tax year, the dividend allowance remains £500. Dividend income above that allowance is generally taxed at the following rates:

Your dividend tax rate depends on your total taxable income, including salary and other income. Dividends falling within your available Personal Allowance may not be taxable, and the dividend allowance applies according to the rules.

It is also important to remember that dividends are distributions of company profits, not business expenses. They cannot be deducted when calculating the company’s Corporation Tax profits.

This means there may be two levels of tax: Corporation Tax on company profits and personal tax when dividends are received.

That does not necessarily mean you are always worse off through a company. It simply means you need to compare the combined tax position rather than looking at Corporation Tax or dividend tax in isolation.

Official guidance is available here: Tax on dividends.

4. Directors’ loans can create unexpected tax charges

Another issue I would encourage every owner-director to understand is the director’s loan account.

If you take money out of your company that is not salary, a dividend or a repayment of money owed to you, the amount may be recorded as a loan to you.

If a loan to a shareholder-director in a close company remains outstanding nine months after the end of the company’s accounting period, the company may have to pay a tax charge under section 455.

For loans made on or after 6 April 2026, the section 455 rate is generally 35.75%.

For example, if a qualifying loan of £10,000 remains outstanding beyond the relevant deadline, the potential section 455 charge would be £3,575, subject to the detailed rules.

This is a company tax charge, not simply a personal Income Tax bill. Relief may be available when the loan is repaid or otherwise dealt with in accordance with the rules, but the timing and conditions matter.

There are also anti-avoidance rules concerning arrangements in which loans are repaid shortly before the deadline and then effectively taken out again.

My advice is to keep your director’s loan account under regular review rather than waiting until the company’s year-end.

5. Selling company property is not the same as selling personal property

If your business owns property or other investments, it is important to understand how incorporation affects the tax position.

When a limited company sells an investment property at a gain, the gain is generally included in its taxable profits for Corporation Tax purposes. The company may have to pay Corporation Tax on that gain.

A company can still benefit from indexation allowance in certain circumstances, but the allowance was frozen at December 2017. It does not provide an ongoing deduction for inflation after that date.

Individuals, on the other hand, may be subject to Capital Gains Tax when they sell personally owned investment property, subject to the applicable reliefs and exemptions.

The tax treatment can be particularly complicated if you are considering transferring an existing property business into a company. The transfer itself may trigger tax, stamp duty land tax or other costs, depending on the circumstances.

For this reason, I would strongly recommend obtaining professional advice before transferring property or other substantial assets into a limited company.

So, should you incorporate your business?(Sole Trader vs Limited Company)

My answer is that it depends on your circumstances.

Incorporation may be suitable if your business is growing, you want to bring in shareholders, you wish to retain profits for future investment or you need the structure of a separate legal entity.

On the other hand, remaining a sole trader may be more straightforward if your business is small, your profits are modest or you withdraw most of your earnings for personal use.

There is no single answer that works for every business owner. Your profits, personal income, family circumstances, business risks and future plans all matter.

I would encourage you to look beyond the headline tax rates and compare the overall costs and benefits before making a decision.
