1. What is the UK Bonus Tax Calculator?

The UK Bonus Tax Calculator for 2024-25 helps estimate the tax payable on bonus payments under the current UK tax system. It applies the appropriate tax rate to your bonus amount to calculate the tax due.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Bonus \) — The gross bonus amount in GBP
• \( Tax Rate \) — The applicable tax rate as a decimal (e.g., 0.45 for 45%)

Explanation: The calculator multiplies your bonus amount by the tax rate you specify to determine the tax due.
