How does HMRC tax your savings income in the 2025/26 tax year? If you’ve ever earned interest on a savings account and wondered how it’s taxed or whether you need to report it, this video clears it all up.

Many people spend their entire working life saving for a variety of things whether it be a comfortable retirement, specific leisure activities or life ambitions.

However, it is easy to forget that if the interest you earn from your savings exceeds a certain limit, then you will be required to pay tax on that interest.

Here’s some information about taxing interest on savings that it is important to be aware of.

Before any tax obligations come into effect everyone is entitled to a Personal Savings Allowance.

The Personal Savings Allowance (PSA) is a tax-free allowance which allows you to earn interest on savings up to a specific amount before you have to pay tax on it. The allowance amount is linked to your income tax rate. So, for example, if you are a basic rate taxpayer, you can earn up to £1000 in savings interest per year without having to pay tax on it. The PSA includes income earned from all savings accounts (except ISAs).

When your combined income and savings interest exceeds your Personal Savings Allowance, then you have to pay tax on it.

Income tax rates and PSA

The table below shows how much interest you can earn on your savings before paying tax (your PSA) depending on your income tax rate.

When do I have to inform HMRC?

Your bank or building society will pay all interest you earn from your savings accounts to you directly. However, while they will not deduct any tax from your savings interest, they are likely to inform HMRC of these payments they make to you.

There are a few different ways to inform HMRC of your savings interest:

1. If you are an employee or have a pension - If HMRC calculate from the information they receive from your bank or building society, that you have tax to pay on your savings interest and you are an employee or have a pension, then you will be given a new tax code which will reduce your personal income allowance to cover the tax payment for your savings interest. However, in this case it is important to note that if your earnings from savings interest drops below the PSA in subsequent years, it is your responsibility to inform HMRC so that your tax code can be readjusted and you don’t end up overpaying tax.
2. If you are self-employed or already complete a Self-Assessment Tax Return (SATR) - If you already complete a SATR, then you will account for any savings interest on your tax return.
3. If income from savings interest exceeds £10,000 - If you earn £10,000 or more from the interest on your savings, this will need to be declared to HMRC by completing a SATR. 

Can I get back any tax overpayments on my savings interest?

If your tax code is changed to account for tax payments on savings interest and then your income from savings interest falls back below the PSA, you could find yourself overpaying tax as your adjusted tax code will remain in place until you inform HMRC otherwise. 

However, if you realise that this has happened, it is still possible to reclaim any overpaid tax up to 4 years after the tax year in which the overpayments were made. You can either do this using your SATR or by contacting HMRC directly. 

Starting rate for savings

Providing your other earned income does not exceed £17,570, you may also be eligible for a tax-free starting rate for savings which can be up to £5000 depending on the amount of income that you earn. 

If you think that you might be eligible for this starting rate, then please get in touch and we can talk through your personal levels of income and advise how much of the starting rate you may be entitled to.

There is a lot to be aware of when it comes to paying tax on your savings interest and it could easily be something that you overlook if you are unaware of how your savings pot has built up over the years.
