Self-employed or limited company: Which is right for you?

When choosing whether to be self-employed or set up a limited company, the answer will depend on a range of factors, including your future growth plans and expected profit levels. As of 2024, there were 3.1 million sole proprietorships and 2.1 million actively trading limited companies in the UK. The number of sole traders has decreased since 2019, while the number of actively trading companies has seen a slight increase. This shows that entrepreneurs are increasingly choosing to set up limited companies as opposed to being self-employed, and for good reason. In this article, we will discuss the factors to consider when deciding whether self-employment or a limited company is right for you.

What Is Meant by “Self‑Employment”?

Being self-employed means that your business has no separate legal personality; effectively, you are the business. In the eyes of the law, you and the business are treated as the same person. You sign contracts in your own name, and you are personally responsible for debts. 

The most common business structures used by those in self-employment are sole traders and partnerships. If you are self-employed, your profits are taxed through Self Assessment as self-employed tax on your personal income. 

Because there is no division between you and the business, you keep all profits after tax. However, you also bear full personal financial responsibility if something goes wrong. That can include unpaid suppliers, loan repayments or claims from customers.

What Is a Limited Company?

A limited company, such as a private company limited by shares, is a legal entity that is registered at Companies House and is legally separate from its owners/members. As such, it exists in its own right and can own assets, sign contracts and borrow money. The key feature of limited companies is that the personal assets of the shareholders and directors are legally protected from the debts and liabilities of the business.  

Limited companies can be of any scale, from small single-owner to multi-national businesses. Shareholders own the company through their shares while directors run the company and make day-to-day decisions. In many small businesses, the same person has both roles. 

Self-Employed vs Limited Company

There are several key differences between self-employment and limited companies:

• Legal separation – a sole trader has no legal separation from the business, whereas a limited company is a separate legal person with its own rights and duties.
• Responsibility and risk – self-employed individuals usually have personal liability for the debts and claims of their business. Creditors can pursue your personal assets if the business cannot pay. In a company, shareholders normally have limited liability. Their risk is usually limited to what they invested, unless they have given personal guarantees.
• Tax – Sole traders pay income tax and National Insurance on profits. A company pays corporation tax on its profits. Owners then pay personal tax on money taken out as salary or dividends. The best choice depends on profit level, sector, growth plans and attitude to risk.

Aspect	Self-employed vs limited company
Legal status	Self-employed owners are not separate from their business, whereas a limited company is a separate legal person.
Liability	A self-employed person is usually personally liable. A limited company offers limited liability to shareholders/
Tax	Self-employed tax uses income tax and National Insurance on profits. Limited company tax uses corporation tax plus personal taxes.
Admin	Self-employed records and returns are simpler. A limited company has more filing and director duties.

Tax Basics for Self-Employed and Limited Companies

Self‑Employment Taxation

If you are self-employed, you will pay personal income tax on your annual profits after allowable expenses. You will also pay Class 2 and Class 4 National Insurance when profits pass certain thresholds. This must be reported through a Self Assessment return each year. You can deduct many business costs before tax, such as business equipment and materials,  travel and professional fees.

Limited Company Taxation

For limited company tax, the company pays corporation tax on its profits. Directors and shareholders then pay personal tax on money they take from the company. This may be a salary, which attracts income tax and National Insurance. It may also be as dividends, which are taxed at different dividend tax rates. The overall position often depends on profit levels and how income is split between salary and dividends.

What Are the Key Benefits of Being Self‑Employed?

Being self-employed in the UK offers several advantages over operating a limited company:

• Reduced administrative burden – typically involves less ongoing paperwork, duties, and obligations compared to managing a company
• Direct decision making – you have direct and personal control over all business decisions without the need for a formal board or shareholder structure
• Profit ownership – you own the business directly and retain all profits after accounting for self-employed tax
• More privacy – Self-employed accounts are kept private and are not filed on the public record, unlike limited company accounts and director details, which appear on the Companies House register
• Simplified tax – the process for reporting taxes is often more straightforward

What Are the Key Benefits of a Limited Company?

Operating as a limited company in the UK offers distinct advantages compared to being self-employed:

• Limited liability protection – if the business is sued or unable to pay its debts, shareholders’ personal assets (such as homes and savings) are generally protected. They only stand to lose the value of their investment in the company (the nominal value of their shares), unless personal guarantees have been made.
• Potential tax efficiency – companies pay corporation tax on profits. Owners can strategically manage how they extract income (e.g., via a combination of salary and dividends). With careful planning, this can lead to a lower overall tax burden than the self-employed tax rules, especially as profits and growth increase.
• Professional image – operating as a limited company can present a more professional image to customers, suppliers, investors, and other stakeholders.
• Easier transfer of ownership –  allows for easier ways to bring in co-owners or sell parts of the business by transferring shares.

Duties and Obligations

Before deciding whether to operate a limited company or through self-employment, it is important to consider your duties and obligations. 

For self-employed people, the main duties are registering for Self Assessment, keeping records and filing a yearly return. You must track income and expenses, keep any business-related receipts and pay self-employed tax and National Insurance by HMRC deadlines. Many self-employed people manage this with simple accounting software or a basic spreadsheet.

The limited liability benefit of a limited company comes with greater levels of duties and obligations that must be met, however. You must register the business with Companies House. You file annual accounts and a confirmation statement. The company files a corporation tax return and pays corporation tax. 

What Are the Legal Duties of a Limited Company Director?

As set out in the Companies Act 2006 (sections 171 to 177). Limited company directors must follow company law duties and adhere to their legal duties, including:

• Duty to act within powers
• Duty to promote the success of the company
• Duty to exercise independent judgment
• Duty to exercise reasonable care, skill and diligence
• Duty to avoid conflicts of interest
• Duty not to accept benefits from third parties
• Duty to declare interests in proposed transactions

Which Is the Right Structure for Me?

When weighing up self-employment against setting up a limited company, many people find that the company structure offers greater overall benefits despite the greater levels of administration and duties. A limited company provides personal liability protection, which means your own assets are shielded if something goes wrong. It can also offer tax planning opportunities, as profits can be taken through a mix of salary and dividends. Clients often see a company as more established, which can support growth and help you secure higher-value work. While self-employment is simple to start, a limited company gives you stronger long-term flexibility and a more professional platform to build from.

Can I Switch from Self‑Employed to a Limited Company?

If you start a self-employed business, you can switch from a sole trader to a limited company in the future. The first step is to choose a company name and structure. You then register a limited company with Companies House either through a company formation agent or directly with Companies House. In addition, you may need to:

• Open a business bank account in your new company name
• Update invoices, contracts, websites and insurance so they show the company name and number
• Tell regular clients that they will now contract with the company rather than you as an individual
• Transfer assets, contracts and ongoing work into the company. This might include tools, stock, intellectual property or customer agreements. It is important to consider tax on any transfers. 
• Tell HMRC about the change – you may need to de-register or amend your self-employed status and set up PAYE for any salaries.

Although you can switch later, it is usually better to start as a limited company if you think you may want the protection that limited liability provides.

Final Words

If you are ready to set up a business in the UK, there is no single answer to whether self-employment or a limited company is right for you. The best option depends on factors such as your profit level, risk tolerance, sector and growth plans, but many people find that starting as a limited company offers clearer advantages. Getting your business structure right can bring real benefits, as it influences how much tax you pay, the level of personal risk you assume, and the amount of paperwork involved. It can also affect how established and professional your business appears to clients, lenders and suppliers, which often works in favour of a limited company.
