Sole Trader vs Limited Company: Key Differences Explained

Every business owner’s journey starts with one question: ‘Should I become a sole trader or form a limited company? This simple, yet crucial, question can change how your company looks and operates. However, what is the difference between a sole trader and a limited company and how can you choose the best structure for your company?

Our blog explains the key differences between the two business organisational structures. We’ll be focusing on key aspects such as liability, tax implications, administrative responsibilities and more.

So keep reading if you’re hoping to start a business but are unsure whether to set up as a sole trader or a limited company set up. 

Key Takeaways

• A sole trader and their business are the same legal entity. A limited company is a separate legal entity from its owner. This is the most fundamental difference between the two structures.
• As a sole trader, you have unlimited personal liability. If the business accrues debt, your personal assets, including your home and savings, could be at risk.
• A limited company offers limited liability. Your personal exposure is restricted to the money or assets you originally put into the business.
• Sole traders pay Income Tax and National Insurance on profits through Self Assessment. Limited companies pay Corporation Tax on profits, and directors can choose how they pay themselves, which can be more tax-efficient in some circumstances.
• Setting up as a sole trader is simpler and involves less ongoing administration. A limited company takes more to set up and has more compliance obligations, including annual accounts and a confirmation statement.
• Limited companies are generally viewed as more credible by banks, investors, and larger clients, which can make it easier to access funding and win contracts.
• You can start as a sole trader and incorporate later. Switching structures is possible, though it's worth checking your preferred company name is available before you do.
• Neither structure is right for everyone. The best choice depends on your risk tolerance, growth plans, and how much admin you're comfortable managing.

What Do Sole Trader and Limited Company Mean?

So before we dive into all the key differences, let's explain what ‘sole trader’ and ‘limited company’ mean.

As a sole trader, your business and you are considered one legal entity, which means you and your business are one in the eyes of the law. This means that all of your profits belong to you, as well as all other legal responsibilities also known as ‘liabilities’. These liabilities include assets (like stock, buildings or equipment) and intangible things such as debt.

As you are solely responsible for your company, you are responsible for all these liabilities. Therefore, if your company has accrued a lot of debt, you are personally responsible for paying off the debt. In the worst-case scenario, you may have to use savings or even sell your car or home to pay off the debt. Only one person can own and operate a sole trader business, the clue is in the name: ‘sole’. Most business owners opt for a sole trader organisation when they begin as it is easier to set up and has a lower administrative burden.

As a limited liability company, you and your business are separate legal entities. This means your business exists on its own. The owner(s) (shareholders) and manager(s) (directors) of the limited company are not responsible for any business liabilities and their personal assets are not tied to the company. You’re only liable for the money/assets you originally put into the business. Finally, unlike a sole trader a limited company can have multiple directors and shareholders.

A limited company protects your assets better than a sole trader organisation. However, it does take longer to set up and has higher administrative requirements, which is why most business owners may opt to incorporate later. 

Liability

Liability is the main difference between a sole trader and a limited company business structure. Simply put, a sole trader has unlimited personal liability when it comes to their company. Whereas, a limited company has limited personal liability– you’ll only be liable for any funds or assets you put into the business.

Essentially, as a sole trader there is a risk that if your business incurs debt or faces legal issues, you will have to pay out of pocket. This can be especially difficult if your personal money is tied to assets like a house or car. If you can’t pay your company’s debts your assets are on the line.

Alternatively, with a limited liability company, your company’s debts are separate from your personal assets. Which means there is less overall risk when it comes to owning an LTD. 

Sole Trader vs Limited Company: Tax Obligations

Of course, tax and tax obligations look different for each company type. As a sole trader, you must pay two types of tax on your profit, Income Tax and National Insurance Contributions (NICs). This is calculated from a yearly ‘Self Assessment’ submitted by you to HMRC.

Because there’s no legal separation between sole traders’ personal finances and those of the business, you’ll pay Income Tax on your profits whether or not you use them personally.

You start paying Income Tax once you earn more than £12,570 in a year. After you cross the threshold you will have to pay a certain percentage of tax.

NICs are paid so that you qualify for government benefits and public services. It is paid by anyone who works. As a sole trader, you will pay class 4 NICs, which were recently reduced to 6% on April 6th 2024.

These taxes are calculated by HMRC using your yearly self-assessment, which means every January you’ll receive a tax bill to cover the previous financial year.

The self-assessment is one of the few administrative obligations you’ll have as a sole trader, but it's important to prepare for it. As a sole trader, you’ll need to budget for an annual tax bill or your tax bill can put you in a tough financial spot. You can use online calculators to determine how much income tax you’ll have to pay so you are prepared.

As a limited company, you'll need to pay Corporation Tax and file a company tax return. Corporation Tax, also known as Company Tax, is paid based on your yearly profits. The current company tax rate is 25.6% and there is no tax-free allowance (as you get with income tax) you start to pay from your first pound of profit.

However, in many ways, you can be more tax-efficient as a limited company. Since you’ll be the company’s director and shareholder, you can choose to pay yourself a smaller salary, to avoid being double charged on National Insurance (a tax which both the employer and employee pay) and pay yourself in dividends. A dividend is a payment made to a shareholder from the company’s profits after tax, and they’re not subject to National Insurance. You’ll still need to pay tax on your dividend income, but Dividend Tax starts at a much lower rate than Income Tax.

Finally, as a limited company, you’ll need to keep on top of your tax obligations. As a company both the company’s profits are taxed as well as the income of any individual within the company. This means more paperwork and more tax rules to follow. However, you can hire an accountant or use accounting software to help you with this. 

Funding and Investment 

Finding funding and investment can be very different for sole traders and limited companies. As a sole trader, you may find yourself relying on your personal savings or taking out a loan for funding. Simply because banks are less likely to fund sole traders due to the issue of unlimited liability and professional image.

However, sole traders do have options like crowdfunding, but some financing sites require a business to issue shares in exchange for funding. To issue shares, you must be a limited company. While finding funding as a sole trader isn’t impossible, it's far harder than a limited company. This can be especially difficult if you are aiming to raise a large amount of capital.

As a limited company, you can access all funding options especially when you offer shares in return. 

Flexibility and Growth Potential 

One benefit of being a sole trader is the flexibility. You will be the sole owner and decision-maker for your company, which means you have total control over your company. This can allow you to adapt quickly and scale up your business well.

As a limited company owner, you may have to go through a structured management process and governance before adapting your business. Of course, if you are the sole director and owner, this will not be the case.

However, overall a limited company is better suited for growth and scalability due to easier access to funding and the structure. As your limited company is a separate entity, it can exist without you. LTDs can have multiple owners and directors in their lifetime- and often do. With a limited company, you have the potential to create a company that lives on even after you choose to move on. 

Credibility and Professional Image 

One final key difference between an LTD and a sole trader is credibility. A sole trader structure may be perceived as being less formal and professional. This can have an adverse effect when applying for funding, trying to secure large contracts or attracting partners. As a sole trader, you pose a risk of losing out due to a lack of a professional image. 

Whereas, with a limited company you are perceived to be more established, stable and trustworthy. This is particularly beneficial if you are seeking funding or trying to secure a large client. You can bring an extra level of professionalism by simply incorporating. 

Still Unsure About Which Structure Type? Here’s a Decision Guide.

There are three main factors to consider before making your decision:

• Risk Tolerance: Consider whether you will be comfortable with the potential of risking your personal assets.
• Growth: Where do you see your business going? If you are hoping to scale it via funding or other avenues, you may want to examine the restrictions of being a sole trader.
• Admin: How much time and resources can you dedicate to tax and yearly filings? A limited company has a lot of extra administrative duties, this can become a burden if you do not have the ability to manage them.

Pros of Being a Sole Trader:

• Less administrative work
• Simple to set up
• Full control and flexibility
• Simpler tax obligations 

Cons of Being a Sole Trader: 

• Unlimited liability
• Limited growth potential
• Less credibility
• Harder to access funding 

Pros of a Limited Company:

• Limited liability
• Better growth potential
• Better credibility
• Easier to access funding
• Tax efficacy

Cons of a Limited Company: 

• More administrative work
• Complex setup
• Ongoing compliance and filings
• More tax obligations 

Conclusion 

There you have it, the key differences between two company organisational structures. Making the decision between a sole transfer and a limited company can be daunting. Take time to understand how each aspect, liability, tax, girth and professional image will affect your company. Ultimately, it's your decision to make, and it is crucial to pick an organisational type that will work for you and your profits.

Don’t forget: if you choose to become a sole trader, you are able to switch to a limited company at any point. However, you may need to make sure your company name is available to reserve and not already in use.

FAQs

What is the main difference between a sole trader and a limited company?

The key difference is legal structure. As a sole trader, you and your business are the same legal entity, so you're personally responsible for any debts the business takes on. A limited company is separate from you, which means your personal assets are generally protected if things go wrong.

Which is easier to set up, a sole trader or a limited company?

A sole trader. You register with HMRC, keep records of your income, and submit a Self Assessment each year. A limited company involves registering with Companies House and meeting ongoing compliance requirements, including annual accounts and a confirmation statement.

Is a limited company more tax-efficient than being a sole trader?

It can be, particularly as profits grow. Limited company directors have more flexibility in how they pay themselves, which some people use to manage their tax position. But the rules are more complex, and what works best depends on your circumstances. An accountant can help you work out which makes more sense.

Can a sole trader have employees?

Yes. Being a sole trader refers to your legal structure, not how many people work in the business. You can take on staff, but you'll need to register as an employer with HMRC and operate PAYE.

Is a limited company more professional than a sole trader?

Many clients, investors, and lenders do view limited companies as more established. It's not a hard rule, but if you're looking to win larger contracts or raise investment, a limited company structure can make a difference to how you're perceived.

Can I switch from sole trader to limited company later?

Yes, and many people do once their income grows or plans become clearer. You'll be registering a new legal entity, so it's worth checking your preferred company name is available on the Companies House register before you make the move.

Do I need an accountant if I set up a limited company?

There's no legal requirement, but many directors choose to use one. The tax and compliance obligations are more involved than for a sole trader, and professional advice is often worthwhile, particularly early on.

What happens to a sole trader business if the owner stops trading?

It ceases to exist, because the business has no legal identity separate from the owner. A limited company continues to exist as a legal entity regardless of changes to its directors or shareholders, making it easier to transfer or sell.
