How tax on a bonus is estimated
Income Tax is calculated on annual pay including the bonus, then on annual pay without it. The difference captures band crossings and the Personal Allowance taper. On GBP 50,000 pay plus a GBP 10,000 bonus, the additional 2026/27 tax in England is GBP 3,946.
Formula explained

Formula
