What is a salary sacrifice scheme?

Salary sacrifice scheme work as a kind of employee benefit by allowing employees to receive non-cash benefits in exchange for giving up a part of their salary.

Salary sacrifice is defined by HM Revenue and Customs (HMRC) as an “agreement to reduce an employee’s entitlement to cash pay, usually in return for a non-cash benefit.”

How does it work?

Salary sacrifice is an agreement between the employer and the employee in which the employee agrees to sacrifice a part of their salary in return for certain benefits of equal value. It means that the employer pays certain agreed-upon benefits directly and the cost is deducted from the employee’s salary. An employee may also sacrifice a bonus or other such one-off item. The deductions in the salary are made before calculating the national insurance contributions and income tax.

What is the purpose of a salary sacrifice scheme?

Salary Sacrifice schemes entail savings for both the employer and the employee in the form of,

  • Tax reduction
  • Less National Insurance contributions (NI)

When employees receive certain benefits from the employer in exchange for salary reduction then tax is applied only to the salary and not to the benefit.

Example of a salary sacrifice scheme

An employee with a weekly salary of £350 has agreed to a salary reduction of £50 in exchange for the non-cash benefit of a childcare voucher. The value of this voucher is equal to £50. Childcare vouchers are exempt from tax and class 1 national insurance contributions up to £55. That is why in this case the payable tax and National Insurance contributions apply to £300 and not to £350, as the employee has agreed to sacrifice £50 of his total salary.

Key considerations of a salary sacrifice scheme

It is important to note that:

  • Not all kinds of non-cash benefits are exempt from payable tax and national insurance contributions.
  • Salary sacrifice should not decrease an employee’s cash earnings to a level below the National minimum wage rate.
