What are the key differences between Ltd and Sole Trader?
Limited Company vs Sole Trader structure fundamentally changes how you are taxed in the UK. A Sole Trader pays strict Income Tax and Class 4 NI on all net profits. A Limited Company pays Corporation Tax on profits, allowing the director to control their personal tax liability by drawing a combination of salary and dividends.
Which is more tax efficient? A limited company has generally become more tax-efficient once annual profits pass roughly £40,000–£50,000, because dividends escape National Insurance. The advantage narrowed on 6 April 2026 when the dividend rates rose to 10.75% and 35.75%, so it is worth running your own figures rather than relying on the old rule of thumb.
Beyond tax, forming a Limited Company provides limited liability protection, protecting your personal assets from business debt. Switching structures can be completed rapidly by expert Small Business Accountants.

These figures use 2026/27 rates for England and Northern Ireland and only the details you have typed in. Scotland and Wales set some of their own rates, and allowances, reliefs, other income and your tax code can all change the answer considerably.
We check the rates behind these tools against GOV.UK and believe them correct to the best of our knowledge, but we cannot guarantee the result is accurate for your circumstances and do not accept responsibility for decisions made on it. Please do not file a return or commit to anything on this figure alone — do your own research, and speak to a qualified accountant who can see your full position.
