Salary sacrifice cap explained
What has been announced
In the 2025 Budget, the Government announced a significant change to pension salary sacrifice arrangements that could affect how many employees save for retirement.
From 2029, National Insurance relief on pension contributions made through salary sacrifice will be capped at £2,000 per year. Any salary sacrifice pension contributions above this level will become subject to both employee and employer National Insurance.
How salary sacrifice currently works
Salary sacrifice is a widely used and tax-efficient method of pension saving. Under this arrangement, employees agree to give up part of their salary, and the employer makes an equivalent pension contribution on their behalf.
Because these contributions are made before tax and National Insurance, both the employee and the employer benefit from reduced NI contributions.
Who will be affected
By limiting this tax advantage to the first £2,000 of contributions, the new measure will have a greater impact on those making larger pension contributions. This often includes higher earners or individuals who have prioritised building retirement savings as part of their long-term financial planning.
Once the cap is exceeded, the effective cost of pension contributions will increase. Industry analysis suggests this may lead some individuals to reduce contributions over time, potentially resulting in smaller pension pots and weaker retirement outcomes.
Why this matters for long-term saving
Salary sacrifice has historically encouraged pension saving by offering a simple and efficient way to benefit from pension tax relief and reduced National Insurance.
The introduction of a cap may weaken this incentive, particularly for employees who previously used salary sacrifice to contribute significant sums to their pension. In response, some employers may review their pension arrangements or adjust contribution structures.
What this means for you
The impact of the cap will depend on your individual circumstances. Employees making more modest pension contributions may see little or no change. It is also important to confirm whether your employer offers a salary sacrifice pension scheme at all.
However, if you are aiming to build a substantial workplace pension, the change may require a reassessment of how your contributions are structured.
This could involve contributing outside salary sacrifice or exploring other tax-efficient pension options, while also factoring in the potential impact on take-home pay if additional National Insurance becomes payable.
Planning ahead
If you have relied on salary sacrifice to maximise pension saving, the cap announced in the 2025 Budget could materially affect your long-term retirement plans. The change does not take effect until 2029, which allows time to review your position and make adjustments.
If you are unsure how these changes may affect you, speaking with a professional financial planner can help you understand your options and plan with confidence.
