Many UK savers are asking how much interest is tax-free this year. With savings rates climbing above 4%, more people than ever are earning interest that could push them over their tax-free allowances. The answer depends on your income tax band and whether you qualify for the starting rate for savings.
The Personal Savings Allowance (PSA) determines how much interest you can earn on non-ISA savings before tax applies. Basic-rate taxpayers can earn up to £1,000 tax-free, while higher-rate taxpayers get £500. Additional-rate taxpayers receive no allowance at all.
There is also a separate rule known as the starting rate for savings, which can provide up to £5,000 of tax-free interest for people with lower non-savings income. Understanding how these allowances work together is key to avoiding an unexpected tax bill.
How much interest is tax-free in the UK?
The amount of savings interest you can earn without paying tax depends primarily on your income tax band. The Personal Savings Allowance and the starting rate for savings are the two main mechanisms that keep your interest tax-free.
Key insights on tax-free savings interest
- Tax-free interest depends on your income tax band: basic rate £1,000, higher rate £500, additional rate £0.
- The starting rate for savings can give up to £5,000 tax-free if your non-savings income is under £17,570.
- Pensioners do not have a special allowance; their state pension income may reduce their starting rate or PSA.
- Interest from ISAs is always tax-free and does not count towards your PSA.
- If you exceed your PSA, you will pay tax at your marginal rate (20%, 40%, or 45%) on the excess.

Do pensioners pay tax on savings interest?
Pensioners are not exempt from tax on savings interest. They are subject to the same Personal Savings Allowance rules as every other taxpayer. However, the way pension income interacts with the starting rate for savings can make a significant difference.
How state pension affects the starting rate
The state pension counts as taxable income. For the 2025/26 tax year, the full new state pension is approximately £11,502 per year. If that is your only non-savings income, you remain within the Personal Allowance of £12,570. That means you could still qualify for the starting rate for savings, potentially earning up to £5,000 in savings interest tax-free on top of your PSA.
When pensioners may pay tax
If a pensioner has additional income from a workplace or private pension, their total non-savings income may exceed the threshold for the starting rate. Once that income goes above £17,570, the starting rate is fully lost. At that point, only the PSA applies. A pensioner who is a basic-rate taxpayer still gets £1,000 tax-free; a higher-rate pensioner gets £500.
Many pensioners on state pension alone may pay no tax on savings interest at all, thanks to the combination of the Personal Allowance, the starting rate for savings, and the PSA. However, those with larger private pensions or additional income should check their total non-savings income carefully. The MoneySavingExpert Personal Savings Allowance guide provides worked examples for different pension scenarios.
How to pay tax on savings interest
If your savings interest exceeds your available allowances, you need to pay tax on the excess. The process depends on how HMRC collects the information and whether you already file a Self Assessment return.
Does HMRC know about my savings interest?
Banks and building societies report interest earned on your accounts to HMRC automatically. If the tax due is small, HMRC may adjust your tax code for the following year to collect the amount. If the amount is larger, or if you are already in the Self Assessment system, you will need to declare the interest on your tax return.
Step-by-step calculation
To calculate what you owe, add up all interest from non-ISA savings accounts. Determine your tax band. Subtract your available PSA and any starting rate you qualify for. Tax the remainder at your marginal rate. The MoneyHelper tax on savings and investments guide includes an interactive calculator that can do this for you.
If your total savings interest is below your PSA and you do not qualify for the starting rate, you usually do not need to do anything. The tax on that interest is automatically waived. You do not need to report it on a tax return unless HMRC specifically asks you to.
How to report and pay
If you need to submit a Self Assessment tax return, you must declare all savings interest in the relevant section. HMRC will calculate the tax due. You can pay online through your HMRC account, by bank transfer, or by cheque. In some cases, HMRC may collect the tax through your tax code instead. The HMRC savings and investments tax page explains the options in detail.
Martin Lewis’s advice on savings interest tax
Martin Lewis and MoneySavingExpert have produced extensive guidance on the Personal Savings Allowance and the starting rate for savings. Their advice is widely cited because it translates complex tax rules into practical steps for everyday savers.
Three tax-free allowances to know
Lewis highlights that savers actually have three tax-free allowances relevant to savings: the Personal Savings Allowance, the starting rate for savings, and the ISA allowance. He notes that many people overlook the starting rate, which can provide up to £5,000 of tax-free interest for those with low non-savings income.
Practical thresholds
At current savings rates, MoneySavingExpert estimates that a basic-rate taxpayer typically needs around £20,000 in a top easy-access account to exceed the £1,000 PSA. A higher-rate taxpayer would need around £10,000 or more in the same account to exceed the £500 PSA. These figures depend on the specific interest rate offered.
Some savers assume that £1,000 is the maximum anyone can earn tax-free on savings, regardless of income. In reality, higher-rate taxpayers only get £500, and additional-rate taxpayers get nothing. Meanwhile, lower-income savers may qualify for an extra £5,000 through the starting rate. Your total taxable income determines which band you fall into, not just your salary.
The Suffolk Building Society guide to tax-free savings interest also provides a clear visual breakdown of the tax bands and allowances.
How has the Personal Savings Allowance changed over time?
The Personal Savings Allowance was introduced in 2016, replacing the earlier 10% savings tax rate. Since then, the allowance amounts have remained unchanged, even as interest rates have risen significantly.
- 2016 – PSA introduced: basic rate £1,000, higher rate £500, replacing the 10% savings rate.
- 2021/22 – Allowances frozen by the government until 2028 as part of broader fiscal measures.
- 2023/24 – Interest rates rise sharply; many savers exceed their allowances for the first time.
- 2025/26 – Allowances remain frozen; HMRC reports increased tax collected on savings interest.
- Outlook – No announced changes; allowances are expected to stay frozen until at least 2028.
What are the common uncertainties about savings interest tax?
Several questions regularly cause confusion among savers. The table below distinguishes between what is clearly established and what remains uncertain or conditional.
| Established information | Information that remains unclear or conditional |
|---|---|
| Basic-rate taxpayers get £1,000 PSA; higher-rate get £500; additional-rate get £0. | Whether you qualify for the starting rate depends on your exact level of non-savings income each tax year. |
| Banks report interest to HMRC automatically. | Whether HMRC will adjust your tax code or ask for a Self Assessment depends on the amount of tax due and your individual circumstances. |
| Pensioners use the same PSA rules as all other taxpayers. | The exact interaction between state pension, private pension, and the starting rate varies per person. |
| If you stay within your PSA, no action is needed. | HMRC may still contact you if their data suggests you owe tax, even if you believe you are within the allowance. |
Why do the rules on tax-free interest matter now?
With savings interest rates above 4–5% in many accounts, a saver with £20,000 or more in a non-ISA account can easily earn £800–£1,000 in interest per year. For a basic-rate taxpayer, that is close to or beyond the £1,000 PSA. For a higher-rate taxpayer with £10,000 in savings, the £500 PSA can be exceeded even at moderate interest rates.
The starting rate for savings is often overlooked. It can benefit people with low non-savings income even if they hold significant savings. For example, a pensioner whose only income is the state pension of around £11,502 may qualify for the full starting rate, allowing them to earn up to £5,000 in savings interest tax-free on top of their PSA. The Av. Share Price: Dividend Forecast 2026 offers a related perspective on how investment income interacts with tax allowances.
By comparison, ISAs shield interest from tax entirely and have an annual subscription limit of £20,000 for 2025/26. Moving savings into a Cash ISA is one way to protect future interest from tax, but the annual limit means it can take time to transfer larger sums.

What should I do next to manage my savings interest tax?
Check your total taxable income for the current year to determine your tax band. Calculate the savings interest you have earned so far across all non-ISA accounts. If that interest is below your PSA and you are not eligible for the starting rate, no action is needed. If your interest exceeds your PSA, review HMRC’s options: a tax code adjustment, filing a Self Assessment, or moving some savings into a Cash ISA to protect future returns.
