What is Salary Sacrifice?

Salary sacrifice (sometimes called salary exchange) is a formal arrangement between you and your employer where you agree to give up a portion of your gross salary. In return, your employer typically provides a non-cash benefit, most commonly increased contributions directly into your workplace pension scheme.

Because you’re ‘sacrificing’ salary before tax and National Insurance (NI) are calculated, you effectively lower your taxable income. This means you pay less income tax and less NI on your revised, lower salary.

How Does Salary Sacrifice Work?

  1. Agreement: You formally agree with your employer to reduce your contractual gross salary by a specific amount or percentage.
  2. Reduced Gross Pay: Your official gross salary is lowered by the sacrificed amount.
  3. Employer Contribution: Your employer usually adds the sacrificed amount directly to your pension pot, often alongside their standard employer contribution.
  4. Tax & NI Savings: Income Tax and Employee National Insurance are calculated on your new, lower gross salary.
  5. Potential Employer NI Savings: Employers also save on their National Insurance contributions (Employer’s NI) because your gross salary is lower. Some generous employers pass some or all of this saving into your pension pot too, further boosting its value (our calculator focuses on employee savings, but check your scheme details!).

Key Benefits of Salary Sacrifice

  • Reduced Income Tax: You pay income tax on a lower amount, potentially saving you money, especially if the sacrifice keeps you out of a higher tax bracket.
  • Reduced National Insurance: You pay less employee NI contributions.
  • Increased Pension Contributions: The sacrificed amount goes directly into your pension, significantly boosting your retirement savings.
  • Potential Employer NI Boost: Your employer might add their NI savings to your pension.
  • Simplicity: Contributions are handled automatically via payroll.

Important Considerations & Disclaimer

While salary sacrifice offers great benefits, consider these points:

  • Lower Gross Salary: Your official salary is lower, which *could* affect things like life insurance cover (if based on multiples of salary), mortgage applications (lenders have different criteria), or entitlement to certain state benefits. Always check potential impacts.
  • National Minimum Wage: Your salary cannot be sacrificed below the National Minimum Wage or Living Wage applicable to you.
  • Scheme Rules: Pension contribution calculations (e.g., whether the employer percentage applies to the original or adjusted salary) vary significantly by scheme. Check your employer’s specific rules.
  • Tax Year & Location: Calculations use 2024/2025 rates for England/Wales/Northern Ireland and assume standard NI Category A. Tax rules change annually, and Scotland has different income tax bands.
  • Not Financial Advice: This tool provides estimates for informational purposes only and does not account for all personal circumstances (like student loans). It is not a substitute for professional financial advice. Consult a qualified financial advisor for personalised guidance.
