Many employers pass their NI saving into the employee's pension.
Salary sacrifice is one of the most tax-efficient ways to pay for employee benefits. By reducing gross salary before tax and NI are applied, both employer and employee save money — and for pension contributions, the savings are substantial.
National Insurance is calculated on gross earnings. When an employee sacrifices part of their salary, both parties pay NI on a lower amount:
| Method | Saves Income Tax? | Saves Employee NI? | Saves Employer NI? |
|---|---|---|---|
| Salary sacrifice (pension) | Yes | Yes | Yes |
| Personal pension (relief at source) | Yes (via relief) | No | No |
| Net pay arrangement | Yes (via net pay) | No | No |
Pension: The most common scheme. Employee reduces gross salary and employer pays that amount as an employer pension contribution. Both save NI; employee also saves income tax.
Cycle to Work: Employer purchases a bike and equipment (up to £1,000 without prior HMRC approval) and the employee repays via salary sacrifice. Both save NI on the sacrifice. After the hire period the employee can purchase the bike at fair market value.
Electric Vehicle (EV) Salary Sacrifice: Employer leases an EV and the employee sacrifices salary to cover the lease cost. Very popular due to the low BIK rate on electric cars (3% in 2026/27). Significant NI savings plus a very low company car tax charge.
Many forward-thinking employers pass their employer NI saving directly into the employee's pension — this costs the employer nothing and boosts employee pensions. Use our workplace pension calculator to model the impact on pension contributions.
