A salary sacrifice pension is a tax-efficient arrangement where an employee agrees to give up part of their salary, and in return, the employer pays that amount directly into the employee’s pension. Instead of being paid as cash income, the contribution goes straight into the pension pot, which can reduce both income tax and National Insurance contributions (NICs).
This arrangement is becoming increasingly popular across the UK because it offers benefits for employees and employers alike, while supporting long-term retirement planning in a simple and structured way.
How a Salary Sacrifice Pension Works
Under a salary sacrifice pension scheme, an employee formally agrees to a lower contractual salary. The employer then makes an equivalent pension contribution on the employee’s behalf. Because the sacrificed amount is no longer treated as salary, it is not subject to income tax or employee NICs.
From an employer’s perspective, pension contributions made this way are treated as an allowable business expense. HMRC guidance on salary sacrifice arrangements confirms that these schemes must be set up correctly to remain compliant. You can read more on this via HMRC’s official guidance on salary sacrifice arrangements.
Tax and National Insurance Benefits Explained
One of the main reasons people choose a salary sacrifice pension is the immediate tax saving. Employees save income tax and NICs on the sacrificed amount, while employers save on employer NICs. Some employers choose to pass part or all of their NIC savings back into the employee’s pension, increasing retirement savings even further.
However, it is important to note that salary sacrifice may affect certain benefits that are linked to salary levels, such as statutory maternity pay or mortgage affordability. This is why professional advice is essential before implementing or joining such a scheme.
Employer Responsibilities and Legal Considerations
For employers, salary sacrifice arrangements must be clearly documented and reflected in employment contracts. The arrangement cannot reduce an employee’s cash pay below the National Minimum Wage. Employers also need to ensure compliance with workplace pension rules, including auto-enrolment obligations.
At Care Accountancy, we regularly help UK businesses review pension arrangements as part of wider tax planning services to ensure they are both compliant and tax-efficient.
Is a Salary Sacrifice Pension Right for Everyone?
While a salary sacrifice pension can be highly effective, it may not suit everyone. Employees close to borrowing for a mortgage or relying on salary-linked benefits should consider the wider implications. Likewise, self-employed individuals cannot use salary sacrifice arrangements in the same way as employees.
