Frequently asked questions
- How much tax do I pay on a £50,000 bonus with a £90,000 salary?
- On a £90,000 base salary in 2026/27, a £50,000 bonus generates £25,771 of Income Tax and £1,000 of employee National Insurance. After PAYE deductions the bonus take-home is £23,229 - an effective marginal rate of 53.5% on the bonus pound.
- What is the effective marginal rate on this bonus?
- 53.5% across Income Tax and employee NIC combined. The bonus sits in higher-rate territory: 40% Income Tax plus 2% NI on earnings above the £50,270 threshold. Salary-sacrificing the bonus into pension would avoid both.
- Would salary-sacrificing this £50,000 bonus into pension be worth it?
- Sacrificing the bonus puts the full £50,000 into your pension pot tax-free vs £23,229 cash in hand - a gain of £26,771 of pension value over cash. The trade-off is liquidity: pension money is locked until age 57 (rising to 58 in 2028). At 53.5% marginal, sacrifice is usually the right call for anyone with adequate liquid savings.
- Why might the bonus payslip show more tax taken than this figure?
- PAYE uses cumulative year-to-date estimates: a one-off bonus in month 6 makes payroll think your annual income has doubled, so the bonus month over-withholds. The remaining months gradually correct it. The annual total reconciles to the figure shown here.
