The 40% higher rate bracket is one of the UK's biggest fiscal cliffs. This calculator shows the exact pound you cross into 40% territory and how much higher rate tax you owe — plus exactly how much pension contribution would pull you back below £50,270.
How 40% tax bracket calculator works in 2025/26
The personal allowance (£12,570) plus the basic rate band (£37,700) gives a higher rate threshold of £50,270 in 2025/26 (frozen since 2021/22). Above this, every additional £1 is taxed at 40%, plus 2% NI = 42% marginal rate.
Crucially, the 40% threshold has been frozen for 8 years through 2027/28 (per Autumn Statement 2022). With wage inflation, fiscal drag is pulling about 7% more workers into 40% each year. By 2027 an estimated 7.8m people will pay higher rate tax — up from 4.4m in 2021.
Common ways to stay under £50,270:
- Salary sacrifice pension (gross-up tax + 8% NI saved = ~42% relief)
- Cycle to work scheme (saves up to 42% on a bike)
- EV salary sacrifice (3% BIK in 2025/26)
- Charitable donations via Gift Aid (no PAYE benefit, but extends basic rate band)
- Increase pension auto-enrolment to 8% personal contribution
Worked example: £50,000 — just below threshold
All earnings within basic rate. Tax £7,486; NI £3,010.60. Take-home £39,503.40 (79.0%).
Gross: £50,000 → Take-home: £39,503.40/year (£3,291.95/month)
Worked example: £55,000 — first £4,730 at 40%
Tax £9,378 (£7,540 basic + £1,838 higher at 40% on £4,730 above threshold). NI £3,104.60. Take-home £42,517.40.
Gross: £55,000 → Take-home: £42,517.40/year (£3,543.12/month)
Worked example: £60,000 + £10,000 pension salary sacrifice
Effective gross £50,000 — pulls you below 40% threshold. Saves £4,210 (£2,000 income tax saved at 40% + £200 NI + £40 employer-passed-back NI possible). Net cost of £10k pension is ~£5,790.
Gross: £50,000 → Take-home: £39,503.40/year (£3,291.95/month)
