The Sole Trader vs Limited Company calculator helps individuals in the UK determine their take-home pay depending on their business structure. Sole traders and limited company directors can use this tool to make informed decisions about which setup might be more financially advantageous in 2026.
How Sole Trader vs Limited Company works in 2026
This tool calculates net income by analysing different tax and National Insurance contributions applicable to sole traders and limited companies. In 2026, sole traders pay Income Tax and Class 2 and 4 National Insurance Contributions (NICs) on their profits. HMRC mandates that sole traders must keep accurate records of their income and expenses to calculate their taxable profit. Income Tax rates for 2026 are set at 20% for earnings between £12,571 and £50,270, 40% for £50,271 to £150,000, and 45% beyond £150,000.
Limited company directors, on the other hand, pay Corporation Tax on profits at a rate of 25% for 2026. Directors can also pay themselves through dividends, which are taxed at different rates: 8.75% for basic rate, 33.75% for higher rate, and 39.35% for additional rate taxpayers. Companies House requires directors to file annual accounts and a confirmation statement. Understanding these distinctions is crucial for accurate financial planning.

Consider using this tool in the following scenarios:
- Scenario 1: Starting a new business and unsure which structure to choose
- Scenario 2: Planning to shift from sole trader to limited company
- Scenario 3: Reviewing tax efficiency before the end of the financial year
- Scenario 4: Estimating the impact of potential income changes on take-home pay

Worked example
Consider John, who runs a consultancy with annual profits of £70,000. As a sole trader, John pays 20% Income Tax on £37,429 (after the personal allowance of £12,570), which totals £7,485.80. He also pays Class 4 NICs at 10.25% on profits above £12,570, totalling £5,901.23.
If John operates as a limited company, he pays 25% Corporation Tax on £70,000, which amounts to £17,500. If he takes home the remaining profit as a dividend, he would pay 8.75% on the first £37,700 (after personal and dividend allowances), totalling £3,298.75. This example shows the different tax impacts of each structure.
Common mistakes
- Not considering all tax implications: Always factor in both Income Tax and NICs for sole traders, and Corporation Tax and dividend taxes for companies.
- Ignoring administrative costs: Limited companies have mandatory filing requirements and potential accountant fees.
- Overlooking VAT registration: Ensure compliance with HMRC if turnover exceeds £85,000.
- Miscalculating dividend taxes: Misunderstanding thresholds can lead to unexpected tax bills.
