How the personal savings allowance works

Introduced in 2016, the UK’s personal savings allowance means most people can earn a certain amount of tax-free savings interest. In this article, we look at how the personal savings allowance works and what happens when you exceed it. We also consider the implications for tax-free savings accounts, such as ISAs.

The personal savings allowance (PSA) lets you earn a certain amount of interest on your savings without paying tax. This tax-free savings allowance is separate from any allowances you might have from ISAs. How much tax-free interest you can earn in a tax year (from 6 April to 5 April) will depend on whether you are a basic rate, higher rate, or additional rate taxpayer:

• Basic rate taxpayers can earn up to £1,000 in interest on their savings

• Higher rate taxpayers can earn up to £500 in interest on their savings

• Additional rate taxpayers do not receive a personal savings allowance.

The tax bands that apply to England, Wales, and Northern Ireland are used to determine your personal savings allowance. While the income tax bands and rates are slightly different for Scottish residents, the personal savings allowance in Scotland works in the same way as the rest of the UK.

This table shows the tax savings allowance for the 2024/25 tax year based on each income tax band:

While lots of people won’t pay tax on their savings interest, recent interest rate rises could increase the risk that more savers will exceed their PSA.

If you are a basic rate taxpayer with a competitive easy access savings account paying 3.40% AER, you would currently need just over £29,412 in savings to exceed your PSA. Higher rate taxpayers with the same account start paying tax on their interest if they have around £14,700 in savings. If this applies to you, you may want to consider utilising tax-free savings options like ISAs (more on this later).If you share a joint account with someone else, interest is usually split equally between you and the other account holder, counting towards each of your allowances.

The personal savings allowance is different to the personal allowance for income tax, also known as the tax-free personal allowance. Most people in the UK are entitled to this personal income tax allowance, which is £12,570 for the current tax year. The personal allowance for pensioners has the same limit. Once your income goes over this threshold, you start paying income tax. 

Your personal allowance might be higher if you claim Marriage Allowance or Blind Person’s Allowance. If your income is over £100,000, your allowance before tax will decrease for every £2 you earn beyond this salary amount.

In addition to the PSA and personal allowance, you might be eligible for a tax-free allowance on interest known as the starting rate for savings. Low earners with a total taxable income of less than £17,570 in 2024/25 are eligible for the starting savings rate. The starting savings rate is a special 0% tax rate on interest up to £5,000. It is reduced for every £1 you earn over your personal income tax allowance, which is set at £12,570 in the 2024/25 tax year.

The PSA applies to any interest earned from the following:

• Bank and building society accounts

• Savings and credit union accounts

• Unit trusts, investment trusts, and open-ended investment companies

• Peer-to-peer lending

• Trust funds

• Payment protection insurance (PPI)

• Government or company bonds

• Life annuity payments

• Some life insurance contracts.

Crucially, it does not apply to interest earned from tax-free savings accounts such as ISAs or some National Savings & Investments products. A separate tax-free dividend allowance applies to dividend income from shares or funds. Different rules also apply to interest earned on children’s accounts and foreign savings.

Any interest that exceeds your PSA will be taxed at your usual rate of income tax. So, if you’re a basic rate taxpayer and you exceed the £1,000 allowance, you’ll be taxed 20% on any interest earned after that. 

Higher rate taxpayers will be taxed 40% on interest that exceeds their £500 PSA. As additional rate taxpayers are not entitled to a PSA, all interest earned on their savings is taxed at 45%.

Thanks to recent increases in interest rates over the last year or so, more people could find themselves exceeding their personal savings allowance. This is one of the reasons why it’s important to keep your savings strategy under review.

Any interest you earn from your savings will be paid to you in full by your bank or building society. If you’re employed or receive a pension and earn beyond your allowance, HMRC will claim back the tax by automatically adjusting your tax code. They will review how much interest you earned in the previous tax year to determine your new tax code.

If you’re self-employed, you’ll need to report any interest earned on your annual Self Assessment tax return.

If you think you’ve paid too much tax on your savings income, you can claim a refund by completing form R40 or applying online. You must do this within four years of the end of the relevant tax year.

You can currently save up to £20,000 per tax year in an ISA and any interest will always be tax-free. This means ISA interest doesn’t count towards your PSA. Whether it’s cash ISAs for savings or stocks and shares ISAs for investments, you will never pay tax up to that amount.

But for many people, historically low interest rates and the introduction of the personal savings allowance means ISAs are not as appealing as they once were. That said, they can play an important role in your overall savings and investment portfolio, especially if you aren’t entitled to the PSA or your savings have reached a level where they could trigger a tax charge.

If your savings income is unlikely to exceed your PSA, it could make sense to consider non-ISA savings accounts. That’s because the top-paying traditional savings accounts tend to offer more competitive interest rates than most ISAs. You can quickly and easily compare competitive savings accounts by visiting the table at the top of this page.

However, if you’re a basic rate taxpayer with substantial savings, or you’re a high earner, ISAs can be very useful. Savings held in an ISA don’t count towards your PSA, so if you’ve used up your £1,000 or £500 allowance, an ISA can still provide you with a tax-free way to save. Likewise, if you aren’t entitled to the PSA because you’re an additional rate taxpayer, an ISA can help to minimise tax and boost your returns.

It’s worth bearing in mind that if interest rates rise, your chances of exceeding your PSA will also increase, particularly if you are a higher rate taxpayer with a reduced PSA. In this case, it may be worth choosing a combination of high-interest savings accounts and ISAs. This would allow you to make the most of both the tax-free allowance on savings and your yearly ISA allowance.

Before taking action, it’s important to compare all the different types of savings accounts you’re eligible for, so you can find one that’s right for your financial circumstances and savings goals.

Some of the most popular types of savings accounts include fixed rate bonds, easy access accounts, and notice accounts.

• Fixed rate bonds – these may be a good option if you have a lump sum of money, as you can lock it away for a set period and earn a competitive rate of interest in return. 

• Easy access savings accounts – if you’re looking for more flexibility, easy access savings accounts allow you to withdraw money whenever you like. However, they tend to offer lower rates of interest. 

• Notice accounts – these types of accounts combine the benefits of both fixed rate bonds and easy access accounts. They give you a degree of flexibility in that you only need to give a short notice period to access your savings (typically between 30 and 90 days). Plus, they also provide competitive rates of interest.
