How Do I Switch From Sole Trader to Limited Company?

Switching from sole trader to limited company means setting up a new company and moving your business into it. A limited company is a separate legal entity, so your sole trader business doesn't convert automatically. You register the company with Companies House, move across your assets, contracts and accounts, and tell HMRC you've stopped trading as a sole trader. Here's how the switch works, and what changes afterwards.

Why Do People Switch to a Limited Company?

Sole trader status is cheaper and simpler to start with, but it can feel restrictive as a business grows. Common reasons for switching include:

Limited liability. As a sole trader, you and the business are the same in law, so you're personally responsible for its debts. A limited company is separate from you, and your personal liability is generally limited to your investment in it.

A different tax position. Sole traders pay Income Tax and National Insurance on their profits, whether or not they take the money out. A company pays Corporation Tax on its profits, and directors can take money out as salary, dividends or both. Corporation Tax applies from the first pound of profit, so whether the structure works out better depends on how much the business earns.

Credibility. Some clients and funders see a limited company as more established, and some require one.

A limited company also means more admin and more rules. Our guide to sole trader vs limited company goes through both sides in more detail.

How Do I Know If It's the Right Time?

Look at your turnover, profit margins and plans for the next year or two. If profits are small or unpredictable, the extra duties may outweigh the benefits for now. If profits are rising, risk is growing or customers expect a company, it may be worth a closer look.

This is the point where an accountant is most useful. They can look at your actual figures and explain how the tax would change.

How Do I Register the Company?

You can register directly with Companies House, use a solicitor or accountant, or use a company formation agent. Mistakes in the application are a common reason for delays or rejections, so it pays to double-check each detail.

You'll need:

• A company name that's unique and follows UK naming rules. Some names and words are restricted. You can use our company name checker to see what's available.
• A registered office address in the UK. This appears on the public register, so many owners use a registered office service to keep their home address private. Our guide explains what a registered office address is.
• At least one director, with their personal details, including a residential address, a service address and a date of birth. Directors must also verify their identity.
• At least one shareholder and details of the shares.
• Articles of association, which set out how the company is run. Model articles are available, or you can have your own drafted.

Registering online with Companies House costs £100. Once it's approved, Companies House issues a Certificate of Incorporation. A shareholders' agreement isn't a legal requirement, but some owners use one to set expectations if there is more than one shareholder.

What Happens to My Assets and Contracts?

Your equipment, vehicles, stock, intellectual property and goodwill belong to you, not the company, so they need to be moved across. This is normally done by the company buying them from you at a fair market value, and putting it in writing.

If the company can't pay for them upfront, it can sometimes record the amount as a loan from you and repay it over time. Moving assets can have tax consequences, such as Capital Gains Tax, so it's worth getting advice first.

Loans, leases and supplier contracts also need attention. Tell the other party about the change. Some lenders and landlords will want to renegotiate terms, or ask for a personal guarantee from the director.

Who Do I Need to Tell?

HMRC. Let HMRC know you've stopped trading as a sole trader. You'll usually need to file a final Self Assessment return and pay anything still owed. Our Self Assessment basics is a useful refresher. The company also needs to be registered for Corporation Tax. If you're VAT registered, speak to HMRC about transferring the registration or cancelling and reapplying under the company's name. Our VAT registration service can help.

Licences and permits. Update any that are held in your name, especially in regulated industries.

Clients and suppliers. Share your company name, company number and new contact details.

Insurers. Policies such as public liability, professional indemnity and employers' liability need updating to the company's name.

Your bank. A limited company needs its own business bank account. Open one in the company's name and keep company and personal money separate.

What Changes After the Switch?

Running a company brings new responsibilities.

Corporation Tax. The company pays Corporation Tax on its profits and files a Corporation Tax return each year. The rate depends on how much profit the company makes, so check the current rates on GOV.UK.

Paying yourself. If the company has employees, including you as a director, it needs payroll. Many directors take a mix of salary and dividends. Our guide on paying yourself as a director explains the options.

Filings. Every year, the company files a confirmation statement and annual accounts with Companies House. Late filings can lead to penalties.

Director duties. Directors have legal duties under the Companies Act 2006, including acting in the best interests of the company and keeping accurate records.

FAQs

When is the right time to switch from sole trader to limited company?

There's no single answer. People often look at it when profits rise, risk increases or customers expect a company. An accountant can advise on timing.

What are the main benefits of a limited company?

Limited liability, a different tax position, a clearer separation between you and the business, and often more credibility with clients and lenders.

Does my sole trader business automatically become a limited company?

No. The company is a new legal entity, so you need to register it and move your business across.

Do I need to tell HMRC?

Yes. Tell HMRC you've stopped trading as a sole trader, deal with your final Self Assessment return, and sort out Corporation Tax and VAT.

What happens to my assets and contracts?

They don't move automatically. Assets are usually sold to the company, and contracts need updating with the new company details.

Do I need a new bank account?

Yes. A limited company needs its own business bank account, separate from your personal finances.

What are a director's responsibilities?

Directors file annual accounts and a confirmation statement, keep accurate records and follow UK company law.
