COMMON QUESTIONS

Frequently asked questions

Why can a bonus be taxed at a high marginal rate?

A bonus sits on top of your other annual earnings, so some or all of it may fall into higher tax or repayment bands.

Does this match an individual payslip exactly?

Not always. PAYE tax codes, payroll timing, benefits, pension scheme rules and rounding can make a payslip differ from an annual estimate.

Does the pension percentage apply to the bonus?

In this estimator the selected pension salary-sacrifice percentage is applied consistently to total annual gross pay. Actual scheme treatment can differ.

Which tax year is used?

The calculator uses the same centrally configured tax-year rules as the main Take Home Pay Calculator.
