1. What is Salary Sacrifice Tax Calculation?

The UK salary sacrifice tax calculation determines how much tax and National Insurance you'll pay after reducing your gross salary through a salary sacrifice arrangement. This can be used for pension contributions, childcare vouchers, or other benefits.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• \( Gross\ Pay \) — Your total annual salary before deductions
• \( Salary\ Sacrifice \) — Amount you're sacrificing from your salary
• \( Tax\ Rate \) — Your income tax rate (as decimal, e.g., 0.20 for 20%)
• \( NI\ Rate \) — Your National Insurance rate (as decimal)

Explanation: The calculation shows how salary sacrifice reduces your taxable income, potentially lowering your tax and National Insurance contributions.

4. Using the Calculator
