Autumn Budget 2025 Snippet – Income Tax thresholds frozen

The Autumn Budget announcement is always a big day in the UK’s financial calendar, and this year was no exception. In the hours leading up to the Chancellor’s speech, there was plenty of speculation-fuelled even more by a last-minute leak from the Office for Budget Responsibility (OBR) about the details of the budget. Social media buzzed, news outlets scrambled to interpret the hints, and many people wondered what surprises might be in store. 

As the Chancellor took to the dispatch box just after lunchtime, the country tuned in to hear what would change for the years ahead. 

There was a lot announced in the budget, which we covered in a deep dive here, but here is a snippet of one of the key topics.

 

Income tax thresholds frozen

What are they?

Income tax thresholds are the levels of income at which you start paying different rates of tax. As your income rises above certain thresholds, you pay a higher percentage in tax. These thresholds are usually reviewed and sometimes increased to keep up with inflation.

What’s changed?

Before this Budget, the main income tax thresholds had already been frozen at their 2021/22 levels and were due to remain unchanged until April 2028. This meant the Personal Allowance (the amount you can earn before paying any income tax) was set at £12,570, and the higher rate threshold (where you start paying 40% tax) was set at £50,270. The additional rate threshold (where you start paying 45%) was £125,140. These thresholds had not been rising with inflation or wage growth, so more people were gradually paying more tax as their incomes increased.

The Government announced that these income tax thresholds will now remain frozen for an extra three years, until April 2031. This means:

This freeze also applies to the equivalent National Insurance thresholds for employers and the self-employed.

Why it matters

Over time it means a larger share of your income could go to tax, even if tax rates themselves haven’t changed.

If you’re working, your pay will hopefully increase over time, in line with inflation. But because the income tax thresholds are frozen and not rising with the cost of living, you’ll find that more of your pay ends up being taxed— even if your income is just keeping up with inflation.

This effect is sometimes called “fiscal drag”. Here’s how it works in practice:

Example 1: Average earner

Example 2: Mid earner

 Example 3: High earner

 Over time, as wages rise but thresholds stay the same, more people will move into higher tax bands, and everyone will pay a bigger share of their income in tax- even if tax rates themselves haven’t changed. This is why the Government expects to raise billions more in tax over the next few years, without increasing the tax rates.

 

What Should You Do Now?

For most people, this Budget doesn’t require urgent action or a change of course. If you’ve been waiting for clarity before making financial decisions, you can continue with your plans. However, it’s important to recognise that, while there are few immediate changes, the impact of frozen allowances and future tax rises will build up over time.

For most, the best approach is to stay on track, keep your plans under review, and be aware of how gradual changes may affect you in the years ahead.
