It’s that time of the year: the 2025 Autumn Budget has officially dropped, and the headlines are rolling in: tax rates have been frozen until 2031.
Pair that with the announced cap of £2,000 on salary-sacrificed pension contributions, and on the surface, it seems like a small change – but for your people, it could shape both how their pay feels now and how secure they feel about the future.
For HR, payroll, and people leaders, this is your moment. A chance to reassure your people, answer their questions, and show support when it matters most – their financial wellbeing.
Understanding the Autumn Budget 2025 changes
On paper, the changes announced in this year’s Budget look simple enough. Tax rates stay exactly where they are for another six years, and there’s now a limit on how much of someone’s pension contributions can be made through salary sacrifice before National Insurance (NI) kicks back in.
What does this mean for your workforce?
The frozen threshold effect
As salaries rise through standard pay reviews, promotions, cost-of-living adjustments, or even National Minimum Wage (NMW) or National Living Wage increases, more employees will naturally move into higher tax bands. This is where the confusion starts, because to most employees, it looks like:
“If I’ve had a pay rise, why doesn’t it feel like one?”
Take, for instance, those on structured pay grades, such as those working in education, healthcare, or the public sector. Moving up one step on a pay scale can suddenly push someone into a higher tax band, even though their role or responsibilities haven’t fundamentally changed.
Whereas, for variable-hour, seasonal, and shift-based workers, their pay may look very different. A quieter week may mean lower earnings and a slight boost in take-home pay because they sit comfortably within their existing thresholds. But a busier month – extra shifts, seasonal overtime, or peak-period demand – might push part of their earnings into a higher band, causing fluctuations they can’t always anticipate.
The £2,000 salary-sacrifice cap
Then we have the new £2,000 limit on how much people can put into their pension through salary sacrifice before they start paying NI on the rest. Which means, anything above that threshold will attract National Insurance in the same way as regular pay.
For employees who like to contribute a bit more into their pension – whether that’s part of their long-term planning, or simply because some months allow for it – this change will, unfortunately, influence how their take-home pay looks.
People on consistent salaries might only cross that limit occasionally, perhaps when they receive a bonus or increase their pension contributions. But for seasonal workers, shift-based employees, and anyone with variable hours, it can happen much more unpredictably. A busier month with extra shifts or overtime could tip them over the cap; a quieter one could bring them back under it.
Often, the first clue will be a slightly different payslip: a higher NI deduction, or a change in net pay they weren’t expecting, which can only spark the following questions:
“Why has my NI gone up this month?”
“Has something changed with my pension?”
That’s why now is the perfect opportunity for employers to step in with clarity. Employees need clear insights that make their pay easy to understand and actionable. But having your payroll team answer every employee (especially at the enterprise level) is simply counterproductive.
“I was disappointed that Pensions salary sacrifice has taken a hit from 2029, as this will have a huge impact on employees saving for their retirement. Anyone earning over £25,000 in a salary sacrifice scheme will feel the pinch in the decreased take home pay. This will also add in more complex steps to assess for NMW, and increase assessable taxable pay for means tested benefits.” – Cybill Watkins, Product Legislation Manager, Zellis Group
How can you support employees?
In our Financial Fitness at Work Report 2025, we asked 2,500 employees across the UK and Ireland about their financial experiences in the past year. You will be alarmed to learn that 92% confessed to experiencing financial stress in the past year, with 89% admitting that it was affecting their performance at work.
It is understandable. Pay is the foundation of financial wellbeing, and when people don’t understand what’s happening with their pay, that uncertainty ripples through everything else.
But when they are more confident about their finances, 78% feel more motivated at work. This is why, as employers of choice, it is the perfect opportunity to give people clarity not only about their contracts and pay, but also about what’s changing and why – building the confidence and trust that leads to stronger performance across your organisation.
How intelligent payslips create clarity
So how do you actually deliver that clarity? Zellis Intelligent Payslips transform standard payslips into something employees can genuinely understand. Employees gain clarity on pay changes, payroll teams spend less time answering queries – everyone wins.
Instead of static payslips – which often mean nothing to most employees – your people get personalised, AI-enabled insights about their pay written in plain English. They see what changed, why it changed, and what it means for their take-home pay. And because the answers are right there on the payslip, your payroll team spends less time fielding the same questions.
Here is what it looks like:
- Clear, plain-language explanations of changes in pay
- Side-by-side comparisons with previous periods
- Visual breakdowns of tax, NI, overtime, and deductions
- Interactive glossary of 900+ payroll terms
- Instant answers to common payroll questions
For example:
“Why has my pay increased by £140.96?”
“In addition to payment for 5 days sickness, your student loan payments have finished, and National insurance contributions have decreased.”
That is clarity at its finest. No confusion, no waiting two working days for an answer on their pay – just straightforward, real-time information that helps people understand what’s happening with their money.
When employees get that level of transparency, they can make informed financial decisions. And your payroll team? They can focus on more strategic work instead of explaining the same things repeatedly.
Building on that foundation
Take an employee whose overtime pushed them into a higher tax band this month. With Intelligent Payslips, they can see exactly what happened and why their take-home looks different.
But then they can go further.
They can go into the Zellis Benefits Checker and check if they are eligible for any benefits to ease their financial burden.
They might decide to start putting a bit of money aside each month into a savings pot through the Zellis platform.
Or say they have an unexpected expense that comes up before payday? With Zellis Earned Wage Access, they can tap into money they’ve already earned without turning to expensive overdrafts, credit cards or loans.
When you combine these tools with Intelligent Payslips, you’re giving your people something valuable: real control over their finances, which carries over into everything that they do at work.
Let’s unlimit what’s next
