What is salary sacrifice?
Salary sacrifice is an arrangement between you and your employer where you agree to give up (sacrifice) part of your gross salary in exchange for your employer making an equivalent contribution to your pension. Because the contribution is made by the employer rather than by you, it is not subject to employee income tax or employee National Insurance contributions.
Your employer also saves their employer's National Insurance on the sacrificed amount. Many employers pass some or all of this saving on to the employee as an additional pension contribution, making salary sacrifice even more attractive.
How the savings work
Let us look at a practical example. If you earn 40,000 pounds and want to put 200 pounds per month into your pension:
Without salary sacrifice
You earn 40,000 pounds and pay income tax and NI on the full amount. Your pension contribution of 200 pounds comes from your net pay. Through relief at source, the pension provider claims 50 pounds of basic rate tax relief, so 250 pounds goes into your pension. Your take-home pay reduces by 200 pounds.
With salary sacrifice
Your contractual salary reduces to 37,600 pounds (a reduction of 2,400 pounds per year or 200 pounds per month). Your employer pays 200 pounds per month directly into your pension. Because this comes off your salary before tax and NI are calculated, you save income tax of 40 pounds and employee NI of 16 pounds per month on the sacrificed amount. Your take-home pay only reduces by 144 pounds, yet the same 200 pounds goes into your pension.
That is a saving of 56 pounds per month or 672 pounds per year on the same pension contribution. If your employer also passes on their NI saving (approximately 27.60 pounds per month at the 13.8 percent employer NI rate), your total pension contribution rises to 227.60 pounds per month at a cost to you of just 144 pounds.
Higher rate taxpayers benefit even more
If you are a higher rate taxpayer at 40 percent, the savings from salary sacrifice are even larger because you avoid 40 percent income tax plus 2 percent employee NI on the sacrificed amount. For higher rate taxpayers, salary sacrifice provides the full tax relief automatically without the need to claim additional relief through a self-assessment tax return, which many higher rate taxpayers forget to do.
Advantages of salary sacrifice
- National Insurance savings: This is the key advantage over standard pension contributions. With relief at source, you only save income tax. With salary sacrifice, you save both income tax and National Insurance.
- Automatic full tax relief: Higher rate and additional rate taxpayers receive full tax relief automatically without needing to claim through self-assessment.
- Employer NI savings: Your employer saves NI too, and many pass this saving on as additional pension contributions.
- Lower student loan repayments: Because your official salary is lower, your student loan repayments (if applicable) may reduce.
- Simple and automatic: Once set up, the arrangement operates automatically through payroll.
Potential disadvantages
- Reduced salary on paper: Your contractual salary is lower, which could affect mortgage applications, life insurance cover based on multiples of salary, and any other benefits calculated as a proportion of your salary.
- Maternity and paternity pay: Statutory maternity pay (SMP) and statutory paternity pay are based on your official salary. If salary sacrifice reduces your salary below certain thresholds, your statutory payments could be lower.
- Not available to everyone: Salary sacrifice requires your employer to offer the arrangement, and not all employers do. It is more common in larger organisations.
- National minimum wage: Your salary after sacrifice cannot fall below the national minimum wage. This limits how much lower earners can sacrifice.
- Reduced state benefits: Because you pay less National Insurance, your entitlement to certain state benefits could theoretically be affected, though in practice this is rarely an issue for most earners.
Who should use salary sacrifice?
Salary sacrifice is beneficial for most employees whose employer offers it, particularly higher rate taxpayers who gain the most from the combined tax and NI savings. However, you should be cautious if your reduced salary could affect mortgage applications, if you are close to or below the national minimum wage, if you might need maternity or paternity pay in the near future, or if your employer does not pass on the NI saving.
How to set up salary sacrifice
Setting up salary sacrifice is straightforward. Speak to your HR or payroll department to find out whether your employer offers a salary sacrifice pension arrangement. If they do, you will typically need to sign an agreement confirming the amount you wish to sacrifice and understanding that your contractual salary will be reduced accordingly.
Most salary sacrifice arrangements allow you to change the amount you sacrifice periodically, usually at annual review points or when your circumstances change significantly (such as marriage, having children, or a change in salary).
Salary sacrifice and the annual allowance
Salary sacrifice contributions count towards your annual allowance of 60,000 pounds. Because both your personal contribution and any employer NI saving passed on are classified as employer contributions, the full amount contributed by your employer counts against the annual allowance. Be mindful of this if you also have other pension contributions or if your total contributions are approaching the allowance limit.
The bottom line
Salary sacrifice is usually the most tax-efficient way to contribute to a workplace pension. If your employer offers it, it is worth taking advantage of unless your specific circumstances make the reduced salary problematic. The combined savings from income tax and National Insurance can significantly boost your pension contributions at no additional cost to you. If you are unsure whether salary sacrifice is right for your situation, a pension adviser can help you weigh the trade-offs.
