NIC changes on pension salary-sacrifice: what’s new

Posted: December 1, 2025

In the 2025 Budget (announced 26 November), the government confirmed a key change to the way pension contributions made via salary sacrifice will be treated for National Insurance purposes.

• From April 2029, only the first £2,000 per tax year of pension contributions made via salary-sacrifice will remain free from NICs.
• Any amount of salary-sacrificed pension contributions above £2,000 will attract the usual NICs for both employee and employer — i.e., the same treatment as ordinary (non-salary-sacrificed) pension contributions.
• Other pension incentives remain unchanged: pension contributions (salary-sacrificed or not) continue to enjoy income-tax relief (within the usual annual/taxation limits).

In short: the “NIC perk” of salary-sacrifice is being trimmed — but not abolished. The first £2,000 of sacrificed contributions will remain NIC-free; amounts above that will no longer avoid NICs.

How it will work in practice — what to expect

For low or modest pension contributors

• If you currently contribute modest amounts to a pension via salary sacrifice (e.g. under £2,000 per year), you will see no change to your NICs benefit under the new rules.
• For many lower or middle-income employees with moderate pension contributions, the £2,000 cap will still cover a large portion of their typical contributions.

For higher contributors or high-earning employees

• Those who use salary sacrifice to contribute more than £2,000 per year will face a new NIC charge on the excess from April 2029.
• This increases the cost of pension saving via this route — reducing the net benefit (take-home pay + employer savings) that the arrangement has so far delivered.
• For employers: the NIC saving on those excess contributions disappears as well, meaning the cost of offering salary-sacrifice schemes increases.
For employers offering pension salary-sacrifice schemes
• Although the change is delayed until 2029, employers should start considering whether to continue current arrangements unaltered.
• Employers may need to re-evaluate the attractiveness of salary-sacrifice schemes for staff, especially higher earners.
• As an alternative, employers might revert to traditional employer pension contributions (which remain NIC-exempt) or redesign remuneration packages to maintain competitiveness. Indeed, some commentators have noted employers could “replicate” the benefit by reducing future salary growth and increasing employer contributions.

Market and industry reaction — sentiment, concerns & outlook

The announcement has already generated a strong response from the pensions industry, employers and employee-benefit advocates:

• The change is expected to raise substantial revenue — the responsible official estimate suggests the measure could bring in around £4.7 billion in 2029–30.
• However, many commentators warn the change could discourage pension saving, especially among higher earners who rely on salary-sacrifice for tax and NIC efficiency.
• Some employers may respond by reducing pension contributions, scaling back other benefits (bonuses, pay increases), or rethinking the attractiveness of salary-sacrifice — potentially weakening pension take-up and long-term retirement savings.
• On the flip side, for employees with modest pension contributions, the change will have little or no effect — and for some, the first £2,000 cap still preserves a meaningful NIC saving.

Overall, the market view is that the change represents a scaling back of a generous perk rather than a wholesale abolition — but one that will reduce the attractiveness of salary-sacrifice for higher earners and many employers.

What this means for RJP LLP clients — and what you should do now

At RJP LLP, we see this change raising important considerations for employers, trustees, and high-earning individuals. In particular:

• Review existing pension salary-sacrifice schemes now: although the cap applies only from 2029, it’s wise to model the impact on take-home pay, employer NIC costs, and overall pension savings as soon as possible.
• Reassess remuneration and benefit strategies: employers may need to reconsider whether to continue salary sacrifice, increase employer pension contributions instead, or offer alternate benefits to retain staff — especially higher earners.
• Communicate with staff early and transparently — employees who have come to rely on salary-sacrifice for NIC savings should be informed about the upcoming change, and potential impacts on net income.
• Consider long-term pension planning: for clients approaching retirement, or those contributing heavily to pension schemes, this may affect the attractiveness of salary sacrifice; alternative pension-contribution strategies may need to be examined.
• Monitor further guidance and legislation: as the new rules come into force in 2029, additional regulations and HMRC guidance may follow — especially around payroll reporting, scheme rules and compliance.

Our view — a pragmatic, but unwelcome shift

The 2025 Budget cap on NIC-free pension salary-sacrifice reflects a broader effort by the government to rebalance pension-related tax relief — particularly where it disproportionately benefits higher earners. From a public revenue perspective, the change may be defensible.

But from the perspective of workplace pensions, employer benefits, and long-term retirement saving, the cap blunts one of the most effective incentives for pension participation — especially for executives, high earners, and those saving aggressively for retirement.

For many employers and employees, it represents a loss of a useful benefit. That said, until April 2029, the existing arrangements remain intact — giving a window of time to plan, communicate with stakeholders, and redesign remuneration or benefits as needed.

At RJP LLP, we anticipate a wave of re-evaluations of benefit strategies and pension planning over the next few years. Now is the time to assess and act — rather than wait until the new rules take effect.
