Open this scenario in the full salary calculator2026/27; standard Personal Allowance with taper, employee NI below State Pension age, no other income, tax-code adjustments or Child Benefit charge. The bonus comparison holds regular pension contributions fixed and excludes contributions on the bonus. It estimates the full-year difference, not the payment-month payslip. Relief-at-source results exclude additional separately claimed tax relief. Salary sacrifice must meet employer and minimum-wage rules.
Is a bonus taxed at a special rate?
A cash bonus is employment income. Its annual tax effect depends on the bands it crosses and any reduction in Personal Allowance. There is no single bonus tax rate that applies to everyone.
Why could the payslip show a different amount?
Payroll can apply cumulative PAYE, while NI and student loans use the pay period’s earnings and thresholds. A large payment in one month may therefore differ from an annualised comparison. This tool does not calculate the exact bonus-month payslip or pension sacrifice of a bonus.
