What £125,140 means in practice
At £125,140, your personal allowance is tapered — reduced by £1 for every £2 above £100,000. Your effective personal allowance is just £0. This creates a brutal 60% effective marginal tax rate in the £100,000–£125,140 range (40% income tax + 20% from losing your allowance). Pension contributions via salary sacrifice are especially valuable here — they can bring your adjusted income below £100,000 and restore your full personal allowance.
Your National Insurance is £4,513 per year (£376/month). NI is charged at 8% on earnings between £12,570 and £50,270. There is no NI-free personal allowance in the same way as income tax — NI starts at your Primary Threshold (£12,570 in 2026/27).
Your pension contribution under auto-enrolment is £2,202 per year. This is 5% of qualifying earnings (the £6,240–£50,270 band). Your employer contributes at least another 3% (minimum £1,321/year). That money doesn't disappear — it goes into your pension pot and receives tax relief on the way in.
