Heads up: this bonus pushes your total income into the higher-rate band. £15,270 of the bonus is still taxed at 20% + 8% NI, but every pound above £50,270 is hit with 40% income tax and just 2% NI (marginal 42%). That's why your effective rate of 33.4% doesn't match any single band — you're straddling two.

Frequently asked
How much tax on a £25,000 bonus in the UK?
On a £25,000 bonus added to a £35,000 salary for 2026-27, HMRC takes £6,946 income tax plus £1,416 employee NI, so you net £16,638 (33.4% deducted). Your marginal rate on the next pound is 42%.
What is the Scotland net on a £25,000 bonus?
£14,903 — that's £1,735 less than England/Wales/NI at a £35,000 salary. Scotland's extra Intermediate (21%), Advanced (45%) and Top (48%) bands create the divergence once you cross into higher earnings.
Can I avoid tax by putting the bonus into a pension?
Yes — bonus sacrifice diverts the full £25,000 into your workplace pension before it's taxed, so you keep all £25,000 as pension contribution instead of a smaller net figure. You skip income tax and both 8%/2% employee NI, and many employers also pass across their 15% employer NI saving. Watch the £60,000 annual allowance cap and tapered allowance if you earn over £260k.
