What Is a Salary Sacrifice Scheme? How It Affects Your Take-Home Pay

What Is a Salary Sacrifice Scheme?

A salary sacrifice scheme (also called salary exchange) is an agreement between you and your employer to reduce your contractual cash pay in return for a non-cash benefit. The benefit is provided from your pre-tax, pre-National Insurance salary, which can reduce the amount of Income Tax and employee National Insurance you pay.

Common benefits include:

• Pension contributions (the most popular use)
• Childcare vouchers (for schemes started before 5 October 2018)
• Workplace nurseries
• Bicycles and cycling safety equipment (Cycle to Work)
• Employer-provided pensions advice

Because your gross salary is lower, you pay less tax and NI. However, your take-home pay also falls because you are receiving a non-cash benefit instead of cash.

How Salary Sacrifice Affects Your Take-Home Pay

Your take-home pay is the amount left after Income Tax, National Insurance, pension contributions, and other deductions. With salary sacrifice, your gross salary is reduced first, so the deductions are calculated on a lower amount. The result is a smaller net pay, but you gain the benefit (e.g., a larger pension pot).

Example for a Basic-Rate Taxpayer

If you earn £35,000 per year and sacrifice £200 per month (£2,400 per year) into your pension:

• Tax saved: £2,400 × 20% = £480
• NI saved: £2,400 × 8% = £192
• Total saving: £672 per year
• Effective cost to you: £2,400 – £672 = £1,728, or 72p per £1 of pension contribution.

Your take-home pay drops by only £1,728, but your pension receives the full £2,400.

Impact on Higher and Additional Rate Taxpayers

Higher-rate taxpayers (40%) and additional-rate taxpayers (45%) save even more. For example, on a £2,000 sacrifice:

• Higher rate: tax saving £800, NI saving £40, total £840 – effective cost £1,160.
• Additional rate: tax saving £1,350, NI saving £60, total £1,410 – effective cost £1,590.

These figures are based on 2026/27 rates from HMRC and GOV.UK guidance.

Student Loan Repayments and Salary Sacrifice

Student loan repayments are based on your gross salary after the sacrifice. If your reduced salary falls below the repayment threshold for your plan, you may pay less or nothing. Thresholds for 2026/27:

• Plan 1: £26,900
• Plan 2: £29,385
• Plan 4: £33,795
• Plan 5: £25,000
• Postgraduate Loan: £21,000

Repayment rates are 9% for undergraduate plans and 6% for postgraduate.

Important Rules and Limitations

National Minimum Wage Constraint

Your employer cannot reduce your cash earnings below the National Living Wage (NLW) or National Minimum Wage (NMW). For 2026/27, the NLW for workers aged 21 and over is £12.71 per hour. If you work 37.5 hours per week, that equates to about £24,785 per year. Your post-sacrifice salary must stay above this level.

Effect on State Benefits

Salary sacrifice reduces the cash earnings on which NI contributions are calculated. This can affect your entitlement to:

• Contribution-based benefits (e.g., Incapacity Benefit, State Pension)
• Statutory payments (e.g., Maternity Pay, Paternity Pay)
• Maternity Allowance

If your average weekly earnings fall below the lower earnings limit, your employer may not have to make statutory payments to you.

Pension Contributions and Notional Pay

Many employers use a notional salary (the salary before sacrifice) to calculate pension contributions, so you are not disadvantaged. Always check with your scheme provider.

Summary

Understanding what a salary sacrifice scheme is helps you make informed decisions about your pay and benefits. It can be a tax-efficient way to boost your pension or access other benefits, but it also reduces your take-home pay and may affect state benefits. Always check the rules with your employer and consider using a calculator to model the impact.
