Whether you’re self-employed or building a new business, the type of business structure you choose can have a significant impact. The two most common are becoming a sole trader or setting up a limited company.

It’s important to choose  carefully, so we’ve created a complete guide to help you decide which is ideal for your business, along with the key differences between the two and each one’s pros and cons.

What are the differences between a sole trader and a limited company?

Choosing between sole trader vs limited company structures can affect everything from how much tax you pay to the types of accidents or damages you could be liable for.

Sole traders

As the name suggests, a sole trader is a self-employed individual, the only owner of the business and completely responsible for it. The owner and the business are classed as one entity. 

The benefits of being a sole trader include minimal paperwork and only needing to pay income tax and National Insurance on your profits via a self-assessment tax return. Sole trader businesses are also simple to set up, so you can start trading as soon as you have all the required insurances or licences. They’re also generally easier to run.

However, because the business is only allowed one legal owner, if the worst should happen, you, as the owner, could lose your savings and/or personal assets and be forced to declare bankruptcy.

Limited companies

Limited companies are legally separate entities from their owners, which reduces liability but does make them slightly more complex to run. 

Choosing a limited company over being a sole trader can come with some helpful tax benefits, including being able to keep profits within the business and pay small salaries with high dividends to reduce your tax bill. However, the main benefit of a limited company is that if a limited company goes bust, the owner's personal assets are not affected. As long as you can prove you have run the company legally and with correct practices, you cannot be pursued for any debts the company has accumulated.

While the financial benefits are substantial, running a limited company isn’t for everyone – there are greater administration and regulation requirements associated, and you will need to pay fees with Companies House and keep detailed records.

How to change from a sole trader to a limited company 

As your business grows, you may be tempted to switch from being a sole trader to a limited company. If you choose to do this, there are important things you should consider.

  • You may need to substitute existing contracts to transfer obligations from a sole trader to a limited company
  • You will need to set up business bank accounts. 
  • Your insurance policies will need reviewing as your new limited company may have different risk profiles and coverage requirements. 
  • Your old sole trader business will need to be deregistered 
  • The new company will need to register for corporation tax, potentially VAT, and PAYE if paying salaries above the threshold. The corporation tax registration must occur within three months of starting the business, or your business could face penalties for late registration. 


Once you have your new business setup, you may turn to other things such as changing its official name – limited companies have more restrictions on what they can be named than sole traders. Check out our guide on how to change the name of your business for more information.
