Net pay for a private tutor with £55,000 of turnover
A private tutor operating as a sole trader with £55,000 of turnover for 2026/27 has taxable profits of £52,250 after the actual business expenses. Income tax on those profits comes to £8,332; Class 4 NI (6% / 2%) comes to £2,302; and the voluntary Class 2 contribution at £179.40 buys a State Pension qualifying year on top.
Net cash after tax + NI: £41,437. Effective rate on turnover: 19.7%. Marginal rate on the next £1 of trading profit: 42%.
The recurring "should I incorporate?" question: at this turnover, a Ltd Co (no pension, same expense pot) would deliver £41,103 net — £334 less than the sole-trader route. There is no clean intersection in the £15k–£400k range examined — one route dominates throughout.
