Salary Sacrifice and Workplace Pensions: What UK Employers Need to Know Before 2029
The headlines about salary sacrifice have been a little alarming. But they shouldn’t be, at least not yet.
Yes, the rules are changing. From April 2029, the National Insurance exemption on salary sacrifice pension contributions will be capped at £2,000 per employee per year. Any contributions above that will attract NI in the usual way. It’s a real change, and employers will need to plan for it. But it is three years away, the current rules are still fully in place, and the window to make the most of them is wide open.
The more pressing concern, looking at new research from Everywhen, is that most employers are not even using salary sacrifice yet. Fewer than half — just 48% — currently offer it for pension contributions. And of those that do, only 35% are planning to review what the 2029 changes actually mean for them.
What salary sacrifice actually does
At its core, salary sacrifice is straightforward. An employee formally agrees to reduce their gross salary, and the employer pays an equivalent amount directly into the employee’s pension. Because this happens before income tax and National Insurance are calculated, both parties pay less.
For employees, the result is a larger pension contribution without as large a reduction in what lands in their bank account. For employers, the NI savings can be considerable. Research shows that just 26% of employers keep those savings within the business. The rest use them to fund benefits platforms, support other staff perks, or pass some or all of the saving back to employees. So for many organisations, salary sacrifice effectively pays for itself and then some.
The scheme is particularly valuable for certain groups of employees. Higher rate taxpayers receive full tax relief on contributions automatically through salary sacrifice rather than having to reclaim it. Employees earning over £100,000 can use it to reduce their adjusted net income, which matters for the tapering of the personal allowance and eligibility for tax free childcare. Parents affected by the child benefit high income charge face similar considerations. These are not edge cases. In a workforce of any reasonable size, there will be employees for whom salary sacrifice makes a material difference.
Why the 2029 cap is not a reason to hesitate
The incoming rule change deserves context. From April 2029, the NI exemption will be capped at £2,000 per person per year. That still represents a real saving. Employers and employees will still benefit. The scheme will still be worth running. What changes is that contributions above £2,000 will no longer attract the full NI relief they do today.
The practical implication is that the next three years are an opportunity, not a reason to pause. Employers who set up salary sacrifice now will accumulate savings at the current uncapped rate until April 2029. Those who wait will lose that window. And for the 57% of employers who currently share some or all of their NI savings with employees, the post-2029 position will require some thought, because there will simply be less to share.
The Everywhen research asked employers what they were planning to do. A third said they would review the impact nearer the time. Three in ten planned to promote their existing scheme more actively. Around one in four were still considering setting up salary sacrifice for the first time. And 18% said they would not be making any changes at all.
That last figure is arguably fine if the business has genuinely weighed the options and made a considered decision. What is harder to justify is the 68% of employers who, according to HR and Benefits, have either made no decision, are putting the matter off, or simply don’t know what to do. This is a financially significant benefit, with a known regulatory change on a known timeline. Leaving it unaddressed is not a neutral choice.
The piece most employers miss: actually telling employees about it
Setting up a salary sacrifice scheme is step one. Making sure employees understand it is step two, and it’s where a lot of organisations fall short.
Salary sacrifice changes a contractual salary figure. It can affect how lenders assess borrowing capacity. It interacts with certain state benefits in ways that not everyone anticipates. These are not arguments against the scheme. They are simply things employees need to know about so they can make an informed choice. Without that information, people opt out of something they don’t understand, and a well-intentioned benefit goes unused.
This is where financial wellbeing education does something that a PDF on the intranet simply cannot. Structured learning, delivered at a pace that suits the employee, builds understanding over time. It helps people see what salary sacrifice means in practice for their pay, their pension, and their tax position. Done properly, it turns a scheme that exists on paper into one that employees actually engage with.
The Aspina platform is built around exactly this gap. Not every business has the time or resource to develop financial education content internally, and even those that do face the challenge of keeping it current as thresholds and regulations change. A specialist training provider removes that burden while ensuring the content is accurate, accessible, and trackable.
What employers should be doing now
For any employer currently running a salary sacrifice scheme, the immediate priorities are to review how the 2029 cap will affect the current setup, to budget for any changes to how NI savings are used, and to actively communicate the scheme to employees before the rules change. If uptake is low, financial wellbeing education is the most direct way to address it.
For employers without a scheme in place, the case for setting one up sooner rather than later is straightforward. Every month without salary sacrifice is a month of NI savings neither the employer nor the employees are seeing. And beyond April 2029, whilst the cap reduces the scale of those savings, the scheme remains worth running.
Either way, it is worth taking proper advice on how a scheme is structured, particularly for employers setting up for the first time. The rules around auto-enrolment compliance are already detailed enough, and adding salary sacrifice arrangements into the mix requires getting the paperwork right. The consequences of getting auto-enrolment wrong are a useful reminder that pension administration is not an area where good intentions hold up under scrutiny.
Salary sacrifice has not lost its value. The rules are changing, but the fundamentals remain sound. For most UK employers, the question is not whether to offer it, but how soon to act.
