Tax Calculation Method: Cumulative (Default): This aims to model a UK PAYE system. Tax is calculated on a year-to-date basis, smoothing the impact of a bonus across all months. This is more typical to how payroll works over a year.

Non-Cumulative: Isolates the entire tax impact of a bonus into the single month it's paid. Non-bonus months are unaffected, making it easier to see the direct effect of the bonus payment on that month's payslip.
