Salary exchange (often referred to as salary sacrifice for pensions) has become a key feature of many workplace pension schemes, helping employers and employees make tax-efficient pension contributions while reducing National Insurance costs.

However, changes announced in the Budget mean that from April 2029,salary exchange pension contributions will be limited to £2,000 per year. While this change is still a few years away, it has important implications for employers reviewing their workplace pension strategy today.

This article explains what the salary exchange changes mean, why they matter, and how businesses can make the most of pension savings and employee benefits while current rules still apply.

Salary exchange allows an employee to give up part of their gross salary in return for an increased employer pension contribution. Because the exchanged salary is removed before tax and National Insurance are calculated, it can be a highly efficient way to save into a workplace pension.

Under current rules, salary exchange can benefit both sides:

• Employees may pay less Income Tax and National Insurance 
• Employers typically reduce employer National Insurance costs 
• More value can be directed into pension contributions

For many organisations, salary exchange plays an important role in shaping employer pension contributions and supporting employee financial well-being.

From April 2029, the government will introduce a cap of £2,000 per year on pension contributions made through salary exchange.

This means that:

• Higher salary exchange pension contributions will no longer be possible 
• The tax and National Insurance advantages will be significantly reduced 
• Existing contribution structures may no longer be as effective

For employers that rely on salary exchange to enhance their workplace pension offering, this change could affect both cost planning and employee benefits.

Although the salary exchange limit does not come into force until 2029, this period before the change represents an important opportunity.

Now is the time for employers to:

• Review how salary exchange is currently used within their workplace pension 
• Ensure employer pension contributions are structured efficiently 
• Confirm that their pension provider fully supports salary exchange arrangements 
• Communicate clearly with employees about making the most of pension savings while allowances remain uncapped

Businesses that act early are better placed to maximise pension value under current rules and avoid last-minute changes later.

Not all workplace pension providers offer the same level of flexibility, governance, or support when it comes to salary exchange and contribution structures.

If your scheme has not been reviewed recently, it may be worth reassessing whether it still aligns with your business objectives and employee needs. We explore this in more detail in our article: Is your workplace pension provider still the right fit?

A structured pension provider review can help identify whether your current arrangement is delivering value now, and whether it is prepared for upcoming regulatory changes.

With changes to salary exchange pensions on the horizon, many employers are choosing to carry out a company pension plan provider review to ensure their scheme remains effective.

Our Company Pension Plan Provider Review Service helps employers assess whether their existing pension provider, contribution levels and salary exchange arrangements are still appropriate, both under current legislation and ahead of the 2029 cap.

This type of review can support better decision-making around employer pension contributions, employee engagement and long-term cost management.

Salary exchange has long been one of the most efficient ways to support workplace pension savings. While it will still exist after April 2029, its impact will be far more limited.

Employers that take action now can:

• Maximise pension savings under current rules 
• Strengthen their employee benefits offering 
• Demonstrate a proactive approach to workplace financial well-being.
