Blue Jay Owner-Manager Tax Index 2026/27 Sole trader vs limited company tax: England, Wales and Northern Ireland Prepared by Blue Jay Accountants Limited Technical lead: Brady Jackson ACMA, CGMA CIMA Chartered Management Accountant Data checked: 5 September 2026 First published: 6 September 2026 What we found Under the baseline assumptions, a one-owner limited company produces more current personal cash than the sole-trader route only between GBP 60,142 and GBP 60,506 of annual business profit. Its maximum advantage is GBP 15.33. The comparison checks profit at GBP 1 intervals from GBP 20,000 to GBP 300,000. The maximum occurs at GBP 60,249. The comparison excludes accountancy and administration costs. Any additional cost of running a company compared with operating as a sole trader would reduce its cash advantage. At GBP 100,000 business profit, personal cash is GBP 69,311 as a sole trader and GBP 65,210 through the best company salary-and-dividend combination. The difference, calculated before whole-pound display rounding, is GBP 4,102. At GBP 250,000 profit, the corresponding personal cash figures are GBP 145,040 and GBP 129,066, a difference of GBP 15,974. At GBP 100,000 profit, the most cash available through a company falls by GBP 1,334 between 2025/26 and 2026/27. Each year uses the salary giving the most cash; business profit and other assumptions stay the same. What these figures mean Tax calculations use England, Wales and Northern Ireland Income Tax rates. Scottish Income Tax is not included in this edition. Business profit is annual profit after ordinary business costs but before owner salary, employer National Insurance or employer pension contributions. Cash is after all relevant annual taxes. The company comparison pays all current-year distributable profit as dividends after salary and company taxes. Assumptions: one shareholder and full-year director below State Pension age, category A National Insurance, England/Wales/Northern Ireland Income Tax, no other income, student loan, associated companies, losses, brought-forward reserves or accountancy/admin costs. The company is not eligible for Employment Allowance. The separate allowance comparison assumes eligibility and the entire allowance available; it does not model the cost of employing another person. At GBP 100,000 profit, taking GBP 12,570 salary and no dividend leaves GBP 67,176 in the company after Corporation Tax. This is company money and later extraction may be taxed. At the same profit, a GBP 20,000 company pension contribution leaves GBP 55,765 in personal cash, using the salary giving the most cash after that contribution. The pension is not spendable cash today. Sufficient pension allowance and deductibility are assumed; future withdrawal tax is excluded. The comparison measures annual cash, not whether incorporation is right for a particular business. Liability protection, commercial needs, pension benefits and future withdrawals can affect that decision. All figures are nominal, without inflation adjustment. Validation Every published result was independently cross-checked against a separately built calculation model. The separate model checks every fundable whole-pound salary for each published company comparison that varies salary. Profit comparisons at GBP 1 intervals verify the crossover points and greatest company advantage. These are calculation checks carried out by Blue Jay, not an external professional review.
