Sole trader vs limited company: which is right for you?

Understanding the Basics: Sole Trader

A sole trader is an individual who owns and runs their business directly. It's the simplest business structure to set up and manage.

Key characteristics:

• No legal distinction: You and your business are legally the same entity. This means you are personally responsible for all business debts.
• Easy to set up: You simply tell HMRC you're self-employed.
• Minimal administration: You report your business income and expenses through a Self Assessment tax return and MTD quarterly returns (if over the relevant threshold).
• Taxed on profits: You pay Income Tax and National Insurance Contributions (NICs) on your business profits.

Understanding the Basics: Limited Company

A limited company is a separate legal entity from its owners (shareholders) and managers (directors).

Key characteristics:

• Separate legal identity: The company is legally distinct from you. This offers limited liability, meaning your personal assets are generally protected if the business incurs debts.
• More complex to set up: You must register your company with Companies House. As of 1 February 2026, the digital incorporation fee is £100 (figures for illustration – check current rates).
• Increased administration: You'll need to file annual accounts with Companies House, a Corporation Tax return with HMRC, and maintain statutory records.
• Taxed on profits: The company pays Corporation Tax on its profits. You, as a director and shareholder, typically take a salary and/or dividends, which are then subject to personal Income Tax and NICs.

Key Differences: Tax and Finance

The tax landscape is often the biggest driver when deciding between these structures.

Corporation Tax vs. Income Tax

• Limited Company: Pays Corporation Tax on its profits. For the financial year starting 1 April 2026, the main rate is 25% for profits over £250,000. A small profits rate of 19% applies to profits up to £50,000, with marginal relief for profits between £50,000 and £250,000.
• Sole Trader: Pays Income Tax on all business profits. For 2026/27, the Personal Allowance is £12,570. Basic rate tax (20%) applies to income between £12,571 and £50,270, higher rate (40%) between £50,271 and £125,140, and additional rate (45%) on income over £125,140 (for England, Wales, and Northern Ireland).

National Insurance Contributions (NICs)

• Sole Trader: Pays Class 4 NICs on profits. For 2026/27, this is 6% on profits between £12,570 and £50,270, and 2% on profits over £50,270. Class 2 NICs are no longer mandatory but can be paid voluntarily at £3.65 a week if profits are below £7,105 to protect your State Pension record.
• Limited Company: As a director, you typically pay Class 1 NICs on your salary. For 2026/27, employees pay 8% on earnings between £12,570 and £50,270, and 2% above that. The company also pays employer's Class 1 NICs at 15% on salaries above £5,000 per employee. The Employment Allowance can reduce employer NICs by up to £10,500 for eligible businesses, though it's generally not available to companies with a sole director.

Drawings vs. Dividends

• Sole Trader: You take "drawings" from your business profits. These are not a business expense and are not taxed separately, as your profits have already been subject to Income Tax and NICs.
• Limited Company: You can pay yourself a salary (subject to PAYE and NICs) and/or dividends. Dividends are paid from post-Corporation Tax profits and are subject to Dividend Tax. For 2026/27, the Dividend Allowance is £500. Dividend tax rates are 10.75% for basic rate taxpayers, 35.75% for higher rate, and 39.35% for additional rate taxpayers.

Key Differences: Administration and Liability

Administrative Burden

• Sole Trader: Simpler. You need to keep accurate records for your Self Assessment tax return.
• Limited Company: More complex. Requires annual accounts and a confirmation statement to Companies House, a Corporation Tax return to HMRC, and payroll administration if you pay yourself a salary. This often means higher accountancy fees.

Personal Liability

• Sole Trader: Unlimited liability. Your personal assets (e.g., home, savings) are at risk if your business cannot pay its debts.
• Limited Company: Limited liability. Your personal assets are generally protected, as the company is a separate legal entity. Your liability is usually limited to the amount unpaid on your shares.

Making Your Decision

Consider these factors:

• Profitability: Higher profits often make a limited company more tax-efficient due to Corporation Tax rates and the ability to extract profits through a combination of salary and dividends.
• Risk: If your business carries significant financial risk, a limited company offers personal asset protection.
• Credibility: Some clients or suppliers may prefer to deal with a limited company, perceiving it as more professional or established.
• Administrative capacity: Are you comfortable with the increased administrative and compliance requirements of a limited company, or will you outsource this to an accountant?
• Future plans: If you plan to seek investment, sell the business, or bring in partners, a limited company structure is usually more suitable.

Common mistakes

• Ignoring the administrative burden: Many business owners underestimate the extra paperwork and compliance required for a limited company.
• Not reviewing regularly: Your business needs change. What was right initially might not be optimal a few years down the line.
• Mixing personal and business finances (sole traders): While legally the same, keeping clear separation helps with record-keeping and understanding profitability.
• Assuming limited liability is absolute: Directors can still be personally liable in certain situations, such as wrongful trading or providing personal guarantees for company debts.
