How bonus Income Tax is estimated
Calculate annual Income Tax on employment pay with the bonus and subtract tax on pay without it. This captures rate-band crossings and the Personal Allowance taper. GBP 50,000 of pay plus a GBP 10,000 bonus results in GBP 3,946 additional tax in England under 2026/27 bands. National Insurance and pay-period PAYE can change the amount withheld from the bonus payslip.
