Frequently asked
How much tax on a £15,000 bonus in the UK?
On a £15,000 bonus added to a £35,000 salary for 2026-27, HMRC takes £3,000 income tax plus £1,200 employee NI, so you net £10,800 (28.0% deducted). Your marginal rate on the next pound is 28%.
What is the Scotland net on a £15,000 bonus?
£9,319 — that's £1,481 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 £15,000 into your workplace pension before it's taxed, so you keep all £15,000 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.
