Autumn Budget 2025: What Could Change for Pensions?

Before we dive in: What follows isn’t based on insider information, and none of it is guaranteed to happen. It’s a summary of publicly available commentary and speculation about what the Autumn Budget might include. The real details will be revealed on 26 November – but in the meantime, we think it’s helpful to explore some of the possibilities and what they could mean for pensions.

As the Autumn Budget draws closer (mark your calendar for 26 November), rumours are flying – and pensions are right in the spotlight. If you’ve heard whispers about changes to tax relief, salary sacrifice, or the much-loved tax-free lump sum, you’re not alone.

Let’s break down what might be on the table, what it could mean for you, and why there’s no need to panic.

Why pensions are back under the microscope

The Chancellor, Rachel Reeves, has hinted strongly that tax rises are on the way – and respected think tanks like the Institute for Fiscal Studies (IFS) are projecting a £22 billion hole in the government’s finances.

Add in self-imposed fiscal rules that make borrowing harder, and suddenly, tax reliefs, including those on pensions, look like tempting targets.

The IFS and other analysts have pointed out that while the government has ruled out raising rates of income tax, VAT, and National Insurance, there’s plenty of room for manoeuvre in more technical areas – like freezing thresholds or trimming back allowances.

1. Salary sacrifice: a smart benefit under review

Right now, many employees boost their pension using salary sacrifice. This approach saves both you and your employer National Insurance – making it a popular and tax-efficient way to save for the future.

But there’s talk the government might change the rules to bring in extra revenue. One idea is scrapping employer NI exemptions, which could net £17 billion. That might make salary sacrifice less appealing to employers, or prompt them to pass the extra cost to employees.

Still, this would be a big move – and not one that could happen overnight. If it’s announced, it would likely come with notice and preparation time.

2. Pension tax relief: could it be capped?

At the moment, pension contributions get tax relief at your marginal rate. That’s 20% for basic-rate taxpayers, but 40% or even 45% for higher earners.

To level the playing field and cut costs, some suggest a flat rate – maybe 30%, or even just 20% for everyone. That would reduce the perk for high earners but boost it for others. A change like this could bring in £15 billion.

Again, while possible, any reform would likely be phased in – and there’s been no official signal that it’s imminent.

3. Tax-free cash: the big unknown

You can currently take 25% of your pension pot as tax-free cash, up to a lifetime cap of £268,275. This perk has long been seen as a cornerstone of UK pension policy – but it could be trimmed back.

The BBC has reported renewed speculation that this allowance could be reduced, possibly to raise funds without breaching headline tax promises.

But before you consider taking action based on rumour, remember: withdrawing early could limit your growth potential and trigger tax liabilities elsewhere. If nothing changes, you could lose out.

4. Lifetime allowance: could it return?

The pension lifetime allowance was scrapped in 2023, but there's talk it could return in a new form. For high savers, that could mean limits on how much can grow tax-free – or even new charges for breaching a threshold.

It’s unclear if this will be part of the Autumn Budget, but it’s something worth watching.

Advice for right now: don’t panic

With the Budget still weeks away, the best advice is to stay calm and avoid knee-jerk decisions.

The BBC and other outlets have repeatedly highlighted the dangers of acting on speculation – especially when it comes to long-term financial planning. If changes come, you’ll have time to adapt. And if they don’t? You’ll be glad you stayed the course.

Chris Eastwood, CEO and co-founder at Penfold, said:

“Tinkering with pension benefits might offer a short-term fix for the Treasury, but it risks long-term harm to people’s financial futures. We believe pension tax relief and incentives shouldn’t be watered down – they’re essential tools to help people across the UK retire with confidence and security. Now more than ever, we need policies that support long-term saving, not undermine it.”

“At Penfold, we know this kind of speculation can feel unsettling – especially when your retirement plans are on the line. That’s why we’re keeping a close eye on the Autumn Budget, and we’ll be ready to guide our customers through any changes with clear, practical support.”

A quick word for accountants and advisers

If you're advising clients, now’s the time to get ahead of the game. Start identifying who might be affected by changes to tax relief, lump sums, or salary sacrifice. The more you know about your clients’ goals and timelines, the better prepared you’ll be to offer meaningful, timely guidance when the Budget lands.

This isn’t just about tax planning – it’s an opportunity to reinforce your role as a trusted adviser.

What’s next?

This year’s Budget will be shaped by tough choices — but also by practical limits and political risks. Pension changes are possible, yes. But they’re likely to be signposted, phased in, and balanced against the need to encourage saving for the future.

If changes do come, we’ll be here to help you understand them – with a full breakdown of any pension changes, what they mean, and how to respond.

Until then, stick to your plan, avoid the headline hype, and remember: pensions are a long game.
