For a self-employed sole trader with £200,000 of taxable profit in 2026/27, profit is well above £125,140, so the Personal Allowance is fully withdrawn and the whole £200,000 is taxable. The first £37,700 is taxed at 20% (£7,540), the next £87,440 (up to £125,140) at 40% (£34,976), and the remaining £74,860 above £125,140 at the 45% additional rate (£33,687), giving total Income Tax of £76,203. Class 4 National Insurance is charged at 6% on profit between £12,570 and £50,270 (£2,262), plus 2% on the £149,730 above £50,270 (£2,994.60), giving £5,256.60. Total deductions leave £118,540.40 after tax and National Insurance -- an overall effective tax and NI rate of just over 40.7%. At £200,000 of profit, most sole traders will already have reviewed incorporation, since a limited company structure can defer tax by retaining profit, allows a mix of salary and dividends taxed more favourably up to certain levels, and opens up pension contributions from company profit before Corporation Tax, all of which become increasingly valuable the further profit rises above the additional rate threshold.
