Rachel Reeves is about to make pension saving a bit more expensive. The chancellor’s planning to cap salary sacrifice schemes in her November Budget—a move that could raise £2bn a year but leave workers and employers footing the bill. Right now, you can divert income into your pension without paying national insurance on it. That’s about to change. With a £30bn black hole to fill, Reeves is eyeing your pension contributions as part of the solution. Here’s what’s coming and why pension experts are calling it the “thin end of the wedge.”
What’s Changing with Salary Sacrifice Pensions?
Currently, salary sacrifice is a win-win. You dodge national insurance contributions (NI) when you funnel salary into your pension, and so does your employer. It’s one of the few tax breaks left that actually feels generous.
But Reeves wants to cap that exemption at £2,000 per employee per year. Anything above that? You’ll pay standard NI rates, eight per cent for most workers.
That might not sound dramatic, but it adds up fast. A basic-rate taxpayer earning £50,270 who saves six per cent of their salary would pay around £80 more in NI annually. Save £5,000 (roughly 10 per cent of a £50k salary) and you’re looking at £240 extra each year.
Employers aren’t escaping either. They’ll lose relief on the 15 per cent employer NI rate applied to contributions above the cap, which could force firms to cut pension contributions or trim pay rises to balance the books.
Why Pension Experts Are Worried
Steve Webb, former pensions minister and now a partner at LCP, isn’t pleased. He reckons the policy punishes companies “doing the right thing” by encouraging retirement saving.
“Once a cap is in place, there will be a widespread expectation that this is the thin end of the wedge and eventual abolition is on the cards,” Webb said.
Translation: if Reeves introduces a cap now, what’s stopping her from lowering it—or scrapping salary sacrifice relief altogether—down the line?
The Society of Pension Professionals echoed the concern, warning that businesses might respond by cutting employer contributions or reducing pay rises. HMRC’s own research found strong opposition among firms, with some saying it could “disincentivise saving into a pension” and hurt morale.
The Wider Tax Squeeze on High Earners
This pension raid isn’t happening in isolation. Reeves is also reportedly weighing up a two-pence income tax increase for anyone earning over £75,000, partly offset by a national insurance cut for lower earners.
If that goes ahead, those earning above £125,000 could pay around £1,700 more in tax each year. Combined with the salary sacrifice changes, high earners are facing a proper squeeze.
The Treasury’s trying to square this with Labour’s manifesto promise not to increase the three main tax rates for “working people”—though critics are calling it a backdoor tax rise.
Business Backlash and Budget Balancing Act
Reeves is also facing pressure from the business community. A group of fintech founders, including bosses from Revolut and OakNorth, recently warned that tax changes risk undermining London’s ambitions as a tech hub.
With her 26 November Budget looming, the chancellor’s walking a tightrope. She needs to convince markets she can repair public finances without looking like she’s raiding middle and higher-income households.
Good luck with that.
The Bottom Line
Salary sacrifice has been one of the best legitimate tax breaks around. If Reeves follows through, it’ll mean higher costs for savers, tighter budgets for employers, and a clear signal that pension tax relief is no longer untouchable.
Whether it’s a sensible revenue raiser or the first step towards dismantling pension incentives entirely depends on who you ask. Either way, if you’re contributing above £2,000 a year through salary sacrifice, your NI bill’s about to get bigger.

FAQ
Q1: What is salary sacrifice for pensions?
A: Salary sacrifice lets you redirect part of your salary into your pension before tax and national insurance are deducted. Both you and your employer currently avoid paying NI on those contributions, making it a tax-efficient way to save for retirement.
Q2: How much more will I pay if the cap is introduced?
A: If you contribute more than £2,000 per year through salary sacrifice, you’ll pay standard NI rates on the excess. For example, if you save £5,000 annually, you’d pay around £240 extra in NI each year as a basic-rate taxpayer.
Q3: Will employers cut pension contributions because of this?
A: It’s possible. Employers will also lose NI relief on contributions above the cap, which could lead some firms to reduce their pension contributions or limit pay rises to offset the higher costs.
Q4: Is this the end of salary sacrifice schemes?
A: Not yet, but pension experts worry it’s the first step. Once a cap is in place, there’s concern the government could lower it further or eventually scrap salary sacrifice relief altogether.
Q5: When will these changes take effect?
A: Rachel Reeves is expected to announce the salary sacrifice cap in her November Budget on 26 November. If approved, the changes would likely take effect in the next tax year, though the exact timing hasn’t been confirmed.
