Pension salary sacrifice changes: what employers need to know
From 2029, salary-sacrificed pension contributions above £2,000 a year will attract employer and employee NICs. Discover what the change means for your business and how to prepare.
The Chancellor’s Autumn Budget delivered a significant update for workplace pension saving – and it’s one that many employers will need to start planning for now. Below, we break down what’s changing, why it matters and the practical steps you can take.
A major shift for salary sacrifice
Salary sacrifice has long been one of the most efficient ways for employees to boost their pension contributions, thanks to its exemption from National Insurance Contributions (NICs). But from April 2029, that exemption is being capped.
Under the new rules, both employer and employee NICs will apply to any salary-sacrificed pension contributions above £2,000 per year. In other words, employees can still sacrifice more than this, but anything above the £2,000 limit will attract NICs as if it were earnings.
Based on today’s NIC structure:
- Employees earning under £50,270 will pay 8% NICs on contributions above £2,000 each year.
- Employees earning above that threshold will pay 2% on the excess.
- Employers will face 15% NICs on any sacrificed amount over £2,000.
The Office for Budget Responsibility (OBR) expects this measure to raise £4.7 billion in 2029–30 and £2.6 billion in 2030–31 – though many commentators are questioning these estimates, as employers have time to adjust their approach well before the change takes effect.
Why does it matter?
Salary sacrifice has been central to workplace-pension strategy for years. It boosts take-home pay, encourages higher contributions, and helps employers stretch their benefits budget further. Research by the ABI ahead of the Budget even suggested that 38% of employees would save less into pensions if salary sacrifice was restricted.
The concern is twofold:
- Higher employer costs
Businesses that currently encourage higher pension saving, or that pass NIC savings back to employees through enhanced contributions, could see their costs rise sharply. Some may decide to scale back their contributions above the auto-enrolment minimums. - Employees may reduce contributions
If take-home pay falls due to new NIC charges, many employees may lower the additional amounts they save to offset the impact. This risks undermining the success of auto-enrolment, which has brought more than 22 million people into pension saving since 2012.
The wider context matters, too. It’s widely recognised that the 8% minimum under auto-enrolment isn’t enough for most people to retire comfortably. Many in the industry have been pushing for higher minimums, but this change arguably makes that less likely.
What this looks like in practice
Take an employee aged 50 earning £40,000 a year. To close a retirement savings gap, they sacrifice £5,000 into their pension annually. Under the new rules, £3,000 of that amount would attract NICs.
At current rates, that means:
- Employee NICs: £240
- Employer NICs: £450
Multiply this across a workforce – particularly one with generous pension allowances – and the numbers escalate quickly. According to the OBR, around 76% of these additional costs are expected to be passed back to employees through lower salaries or reduced employer contributions.
And because bonus sacrifice has relied heavily on NIC efficiencies, its use is likely to diminish significantly once the cap comes in.
What should employers do now?
Although the change doesn’t take effect until April 2029, the long lead time is intentional – the Government expects employers to start adapting.
Key actions to consider include:
- Model the financial impact
Understand how the NIC changes will affect your payroll and benefits costs. - Review pension scheme design
Look at alternative contribution structures or reward models that could be more sustainable. - Explore offsetting opportunities
For example, benefit redesign, renegotiated insurance premiums or scheme consolidation. - Prioritise what employees value most
If cost-cutting becomes necessary, focus on benefits with the highest perceived value. - Plan your communications
Clear messaging will be essential, both to maintain trust and to help employees understand their take-home pay.
Some employers may even decide to use the transition period to reshape their pension strategy completely – for instance, moving towards fully employer-funded pension contributions to avoid the new NIC charge.
