Salary Exchange Pension FAQ
Everything you need to know about salary exchange, how it reduces your tax and National Insurance, and what it means for your take-home pay and pension pot.
Salary exchange, also known as salary sacrifice, is an arrangement where an employee agrees to give up part of their gross salary in return for the employer paying an equivalent (or enhanced) amount directly into their pension as an employer contribution. Because the sacrificed amount never counts as salary, it is not subject to Income Tax or National Insurance.
Because the sacrificed salary is paid into the pension as an employer contribution rather than as pay, the employee avoids paying Income Tax and employee National Insurance on that amount. The employer also avoids paying employer National Insurance on the sacrificed amount, and many employers reinvest some or all of this saving back into the employee’s pension.
For the 2026/27 tax year, employees typically pay 8% National Insurance on earnings between the Primary Threshold and the Upper Earnings Limit, and 2% above that limit. Employers typically pay 15% National Insurance on earnings above the Secondary Threshold. These rates can change, so always check current HMRC guidance.
Because salary exchange reduces your contractual gross salary, it can affect salary-linked benefits such as mortgage applications, life assurance multiples, statutory maternity or paternity pay, and means-tested state benefits. It’s worth checking with your employer or a financial adviser before agreeing to a large sacrifice.
No. Employers must ensure that salary sacrifice arrangements do not reduce an employee’s cash pay below the National Minimum Wage or National Living Wage. Employers typically cap or restrict sacrifice amounts for lower earners to comply with this rule.
No. The value of salary exchange depends on your marginal Income Tax rate, your National Insurance rate, and whether your employer reinvests any of their own NI saving into your pension. Higher-rate and additional-rate taxpayers, and those who lose child benefit or personal allowance at certain income thresholds, often see larger relative savings.
