Warwickshire expert says make sure you are not one of the 1.2 million UK saves facing an unexpected tax bill

As fixed-rate savings accounts begin to mature across the UK, many savers are receiving more interest than ever before.
While that is great news on the surface, it could come with an unexpected sting: a surprise tax bill.
There could be unexpected tax implications if you are not prepared in advance.
Thanks to recent Bank of England interest rate rises, savers are finally enjoying healthier returns.
However, that also means more people are now exceeding their Personal Savings Allowance (PSA) - the amount of interest you can earn tax-free each tax year.
With around 1.2 million fixed-rate accounts maturing in 2025 alone, this is a growing concern for households who may not realise they have tipped over the threshold.
Your PSA depends on your income tax rate:
- Basic rate taxpayers (20%) get a £1,000 PSA
- Example: £20,000 saved at 5% = £1,000 interest – PSA used up
- Higher rate taxpayers (40%) get a £500 PSA
- Additional rate taxpayers (45%) get no PSA
If you earn more interest than your PSA allows, that extra amount is taxed at your income tax rate.
HMRC may adjust your tax code or require you to declare it via a self assessment.

One simple way to protect your interest from tax is through an ISA (Individual Savings Account).
Interest earned within an ISA is always tax-free, no matter how much you earn - making them a highly effective tool for tax-efficient saving.
- Check your savings statements - Review how much interest you've earned, especially if you have fixed-rate accounts maturing this year.
- Know your PSA - Make sure you understand your tax band and how much interest you can earn tax-free.
- Review your options - Think about whether moving some savings into a cash ISA would help protect your future earnings from tax.
Understanding the savings tax rules can be tricky - but you do not have to go it alone.
