Millions of workers are being urged to make the most of salary sacrifice pension arrangements before the tax break is pared back in April 2029. The scheme lets employees swap part of their pay for pension contributions before income tax and National Insurance are applied, which can lower monthly deductions while boosting retirement savings. Pension specialists say that, for those who can afford to do so, the next few years may offer an opportunity to lock in valuable savings before the rules change.

National Insurance relief set to be capped from 2029

According to the Government, the planned reform will cap the National Insurance exemption on employee pension contributions made through salary sacrifice at £2,000 a year from 6 April 2029. Contributions above that threshold will be subject to both employee and employer National Insurance contributions, with ministers saying the measure is intended to make the system fairer and more sustainable. Further guidance is expected before the new rules take effect.

Millions of savers likely to be affected

Industry figures suggest the arrangement is already widely used. HMRC data show around 7.7 million employees contribute to pensions through salary sacrifice, while more than 3.3 million are paying in above the £2,000 level and are therefore likely to be caught by the reform. Jason Hollands of Bestinvest by Evelyn Partners told The Guardian that making use of the current rules over the next three years "really makes sense", particularly for people who plan to increase their retirement saving later in life. Former pensions minister Steve Webb was even more direct, saying: "Anything you can sacrifice before April 2029 is worth a look."

Benefits come with important considerations

The potential appeal goes beyond pension saving alone. Because salary sacrifice lowers taxable pay, it can also help some workers reduce higher-rate tax liabilities or cut charges linked to Child Benefit. But advisers also warn that the arrangement is not suitable for everyone. It depends on an employer offering it, and reducing contractual salary can affect entitlements such as maternity pay, sick pay and even some mortgage assessments.

Reward Strategy’s Say

The planned changes to salary sacrifice pensions highlight the importance of clear employee communication around financial wellbeing. While the 2029 reforms may encourage some workers to maximise contributions under the current rules, the reality is that salary sacrifice remains a complex benefit with both advantages and trade-offs. This presents an opportunity to educate employees on how pension savings, tax efficiency and wider financial planning fit together, while ensuring they understand the potential impact on areas such as maternity pay, sick pay and borrowing.

As pension costs and retirement adequacy continue to climb the HR agenda, organisations that provide accessible guidance and support are likely to see greater engagement with one of their most valuable employee benefits.
