The interest you earn on your savings is considered taxable income in the UK. Whether you actually have to pay tax on it depends on how much you earn and which income tax band you fall into.
You are likely to pay tax if you are an additional-rate taxpayer, a higher earner with substantial savings, or if your total income exceeds the personal allowance thresholds.
An understanding of how saving interest is taxed is essential to manage your finances effectively and avoid any unexpected tax bills from HMRC.
What Counts as Savings Interest in the UK
Not all savings returns are taxed the same way, which is why it is important to know exactly what HMRC considers “savings interest” versus other types of investment income.
Savings interest refers to the income you earn for depositing your money with certain financial institutions. These include:
- Bank and building society savings accounts
- Credit union savings accounts
- Unit trusts, investment trusts and other collective investments#
- Government and company bonds (including fixed-rate bonds)
- Trust funds
- Payment Protection Insurance (PPI)
- Life annuity payments and certain life insurance contracts
What Does Not Counts as Savings Interest in the UK
It is also important to know what does not count as savings interest as some returns are taxed under different rules. Some of the most common ones are mentioned below:
- Dividends from shares (taxed under dividend allowance rules)
- Income from peer-to-peer lending (unless within an Innovative Finance ISA)
- Returns from investment funds (unit trusts, OEICs)
- Cryptocurrency gains (subject to Capital Gains Tax)
- Rental income (taxed as property income)
- Premium Bond prizes
- National Lottery winnings (completely tax-free)
How Much Interest on Savings Is Tax Free in the UK
Every individual in the UK is entitled to a certain amount of tax-free savings interest, depending on their income tax brand. This is a simple concept known as Personal Savings Allowance (PSA). PSA is separate from your Personal Income Tax Allowance, and acts as an added bonus to your savings.
If you are a basic-rate taxpayer, earning between £12,571 and £50,270, you can earn up to £1000 in savings interest without paying any tax.
And If you are a higher-rate taxpayer, earning between£50,271 and £125,140, the first £500 of your savings interest is tax-free.
If you fall under the additional-rate taxpayer bracket and have income over £125,140, all the savings interest you earn is considered taxable.
Let’s look at some real-world examples:
Example-1
Basic-Rate Taxpayer: Daniel is a nurse who earns £35,000 per year. He has £20,000 saved in various accounts, with £600in annual interest. Because he is a basic-rate tax payer and his savings interest falls within the £1000 PSA, Daniel does not have to pay any tax.
Example-2
Higher-Rate Taxpayer: David is a head-teacher earning £52,000, which makes him a higher-rate taxpayer. He has significant savings built-up and earned £750 interest this year. His PSA is £500, so he has to pay tax on the remaining £250 at his savings tax rate.
Example-3
Additional-Rate Taxpayer: Maria is a company Director with income exceeding £130,000. As she falls under the additional-rate taxpayer bracket and has no PSA, she has to pay tax on all of her savings interest.
How To Use Your Personal Allowance and Starting Rate for Savings Interest
You can also use your Personal Income Tax allowance (£12,570) to earn tax-free interest as long as you have not used this allowance on your wages, pension or other income.
Example-4:
If you have earned £10,000 in the current tax year from your only source of employment and you have received £200 in savings interest, then your personal allowance will first cover your £10,000 wages. The remaining £2,570(£12,570 – £10,000) of unused allowance can be applied to your savings interest. Since £200 falls within this £2,750 buffer, you won’t have to pay any tax.
After Personal Allowance, you may also be eligible for a Starting Rate of Savings of up to £5,000 in tax-free savings interest. This allowance is only applicable if your non-savings income (wages and pension) is below £17,570.
For every £1 you earn above your Personal Allowance (£12,570), up to the £17,570 limit, your starting rate for savings goes down by £1.
Example-5:
Lynn earned £14,500 in wages this tax year. Her income calculated above the Personal Allowance would be £1,930 (£14,500 – £12,570). In such a case her starting rate would reduce from £5,000 to £3,070 (£5,000 – £1930). This means she can only earn up to £3,070 in savings interest without paying any tax.
Example-6:
Steve is earning £18,000 in wages, which means his income sits above the £17,570 non-savings income limit. Hence he will not be eligible for any tax-free savings interest.
When You Will Have to Pay Tax on Savings Interest
You will be required to pay tax on savings interest in these situations:
1. Your exceed your Personal Savings Allowance (PSA)
If you are a basic-rate taxpayer and you are earning over £1,000 in savings interest, you will have to pay tax on it. For a higher-rate taxpayer, earning interest over £500, the excess becomes taxable. If you are an additional-rate taxpayer, you get no savings allowance and all your savings interest is considered taxable.
2. Your total income pushes you into a higher bracket
Even modest savings can become taxable if your income is pushed into the higher or additional-rate band. For instance if you were in the basic-rate tax band and your income has increased just £1 over £50,270, your PSA would be halved from £1,000 to £500.
How Savings Interest Is Taxed by HMRC
Tax on Savings interest, like any other income is added to your wages, pensions, dividends, rental profits and self-employment profits. Using this total, HMRC determines what tax bands you fall into, how much tax you need to pay and what allowances you qualify for.
For employees and pensioners, financial institutions like banks and building societies report your interest earnings directly to HMRC, who then adjust your tax code to collect any tax owed, from your income.
If you are self-employed, you are generally required toreport any savings interest as part of your Self-Assessment Tax Return. Below mentioned are some of the other instances where you must complete a Self-Assessment return:
- Your total income from savings and investments exceeds £10,000
- Yours savings interest earned is above your available tax-free allowances
- You’re a higher or additional-rate taxpayer and HMRC hasn’t given you the correct tax code.
- You receive interest from overseas accounts or informal arrangements (like lending to family)
- HMRC specifically asks you to complete a return.
How to Reduce or Avoid Tax on Savings Interest (Legally)
Keeping accurate records
There are some other legal ways to avoid tax on savings interest. Some of these are mentioned below:
Cash Individual Savings Accounts (ISAs)
Cash ISAs act as a legally protected shelter for your savings, hence any interest earned on these savings is permanently tax-free. The government has set up a £20,000 annual allowance which means you can only save up to £20,000 across all your ISAs in the 25/26 tax year.
Cash ISAs are best for higher and additional-rate taxpayers, you have used up their Personal Savings Allowance and want to make sure their interest is protected.
Spread savings between spouses or civil partners
If your partner pays less tax or hasn’t used up their allowances, transferring your savings into their name can help you significantly reduce your household’s tax on savings interest. This works because transfer of savings between spouses or civil partners is tax-free and allows you to use both sets of allowances.
Fixed-rate Bonds
If you’re close to a tax band threshold, consider having a fixed-rate bond. These allow you to keep a track of time when the interest is paid out.
Example- 7:
Your early income is £49,200, but you are expecting a bonus that will push you into a higher-rate tax bracket. In such a case, if you have a fixed rate bond, you can time your savings’s Interest to land in a tax year when your income is lower.
What This Means for You as a UK Taxpayer
Most basic-rate taxpayers pay nothing on savings interest because Personal Savings Allowance, starting rate, and personal allowance shield them from tax entirely.
But as your wealth grows, so does the complexity of taxes. If you are a higher or additional-rate taxpayer, it is worth reviewing your position. Even a small rise in interest can tip you into a high-bracket taxpayer and cost you more tax than expected.
It is always recommended to keep meticulous and accurate records of all your savings accounts and the taxes earned, this helps you spot errors in your tax codes before they become problems.
