What is the difference between a Limited Company and Sole Trader?

A sole trader is a self-employed person who owns and runs their own business as an individual. A limited company is a separate legal entity owned by shareholders, offering limited liability protection. Sole traders pay income tax and Class 4 NIC on profits, while limited companies pay corporation tax on profits and directors pay income tax on salaries and dividend tax on dividends.

When is a Limited Company more tax-efficient than a Sole Trader?

Limited companies typically become more tax-efficient when annual profits exceed £50,000. This is because corporation tax (19%) is often lower than income tax rates, and dividend extraction can be more tax-efficient than taking all profits as income. However, the exact savings depend on your specific circumstances.

What is corporation tax in the UK 2026/27?

For the 2026/27 tax year, UK corporation tax rates are: 19% for small profits up to £50,000, 25% for profits over £250,000, with marginal relief applying between £50,001 and £250,000.

Do I pay National Insurance as a Limited Company director?

Yes. As a limited company director, you pay Employee NIC at 12% on salary between £12,571 and £50,270, and 2% above that. The company also pays Employer NIC at 13.8% on salary above £9,100. However, you can minimize NIC by taking a low salary and extracting profits as dividends.

How is dividend tax calculated in the UK?

Dividends are taxed at three rates: 8.75% (basic rate), 33.75% (higher rate), and 39.35% (additional rate). There's also a £500 dividend allowance before tax applies. The rate depends on your total income including salary.
