Many UK savers are receiving tax notification letters from HMRC warning that their interest earnings may exceed the Personal Savings Allowance (PSA). With rising interest rates, thousands of people are now unexpectedly liable for tax on their savings.
If you have received an HMRC letter—or suspect you may owe tax—this guide explains:
- How the PSA works and whether you are affected.
- How to check your savings interest tax liability.
- What steps you can take to legally reduce your tax bill.
- Why tax letters have been delayed until March 2025.
Key Details on HMRC’s Savings Tax Crackdown
| Aspect | Details |
|---|---|
| Personal Savings Allowance (PSA) | Basic-rate taxpayers: £1,000 tax-free interest. Higher-rate taxpayers: £500 tax-free. Additional-rate taxpayers: No allowance. |
| Impact of Rising Interest Rates | Banks now offer ~5% interest rates, pushing more savers above the PSA threshold. |
| HMRC Notifications | Letters are being sent to those earning taxable savings interest. P800 tax calculations delayed until March 2025. |
| Tax on Savings Interest | Interest above the PSA is taxed at 20% for basic-rate taxpayers, 40% for higher-rate, and 45% for additional-rate taxpayers. |
| Ways to Reduce Tax Liability | Monitor savings interest, use ISAs for tax-free interest, stay informed about HMRC notifications, and consider alternative tax-efficient savings options. |
How Does the Personal Savings Allowance (PSA) Work?
The Personal Savings Allowance was introduced in 2016 to allow individuals to earn a certain amount of interest tax-free. Your allowance depends on your income tax bracket:
- Basic-rate taxpayers (20%) – Up to £1,000 interest tax-free.
- Higher-rate taxpayers (40%) – Up to £500 interest tax-free.
- Additional-rate taxpayers (45%) – No tax-free allowance (all interest is taxable).
If your interest earnings exceed your PSA, the excess amount is taxed at your standard income tax rate.
Example of PSA in Action:
- A basic-rate taxpayer earning £1,200 in interest will pay 20% tax on the extra £200, amounting to £40 in tax.
- A higher-rate taxpayer earning £800 in interest will pay 40% tax on £300, resulting in £120 in tax.
Many savers with balances over £3,500 are being contacted by HMRC because rising interest rates have pushed them over their PSA limit.
Why Are Savers Being Targeted?
Interest rates on savings have risen significantly over the past two years, with banks offering 5% interest or more. This has increased the amount of interest earned on savings, leading to higher tax bills for many.
How Savings Interest is Now Taxed:
- A saver with £10,000 at 5% interest earns £500 per year.
- A saver with £20,000 at 5% interest earns £1,000 per year, reaching the PSA limit for basic-rate taxpayers.
- A saver with £30,000 at 5% interest earns £1,500 per year, exceeding the PSA and owing tax.
Because of these increases in savings interest, HMRC has started issuing tax warnings to ensure individuals report and pay the correct tax on their savings.
Delayed Tax Notifications – Why Some Savers Won’t Know Until March 2025
Usually, HMRC sends P800 tax calculations in November each year, notifying taxpayers of any tax owed. However, due to the huge increase in taxable savings interest, some P800 letters are delayed until March 2025.
This means many people may not realize they owe tax until just before the new tax year begins.
How to Check If You Owe Tax on Your Savings
If you have received an HMRC letter or suspect you might owe tax, follow these four key steps:
1. Check Your Bank Statements
- Your bank or building society should provide annual statements detailing how much interest you earned.
- Some banks also provide a breakdown of taxable and non-taxable interest.
2. Use HMRC’s Personal Tax Account
- Log in to HMRC’s Personal Tax Account to check your tax status.
- This account will show if HMRC has recorded taxable interest on your savings.
3. Calculate Your Tax Liability
Compare your total interest earnings with your PSA allowance.
| Taxpayer Category | PSA Allowance | Tax on Interest Above PSA |
|---|---|---|
| Basic Rate (20%) | £1,000 tax-free | 20% tax on excess interest |
| Higher Rate (40%) | £500 tax-free | 40% tax on excess interest |
| Additional Rate (45%) | No allowance | 45% tax on all savings interest |
4. Wait for HMRC’s Tax Letter
If you exceed your PSA, you may receive a P800 letter or Simple Assessment from HMRC outlining how much tax you owe.
How to Reduce Your Tax Liability on Savings
1. Use an ISA (Individual Savings Account)
- ISAs allow you to save up to £20,000 per year tax-free.
- All interest earned inside an ISA is exempt from tax, making it one of the best ways to reduce your savings tax liability.
2. Consider Premium Bonds
- NS&I Premium Bonds offer tax-free prizes instead of interest.
- If you win, prizes are tax-free, and your savings remain untouched.
3. Spread Savings Across Family Members
- If you have a partner who pays a lower tax rate, consider splitting savings to maximize both of your tax-free allowances.
4. Claim the Starting Rate for Savings
- If your total income (excluding savings interest) is below £17,570, you may qualify for an extra £5,000 of tax-free savings interest.
What Should Savers Do Now?
- Check your interest earnings – Look at your bank statements and track your total interest earned.
- Review your PSA allowance – If your savings interest is above the limit, you may owe tax.
- Use tax-free savings options – ISAs, Premium Bonds, and tax-efficient savings accounts can reduce your tax bill.
- Monitor HMRC updates – If you exceed your PSA, you may receive a P800 tax letter by March 2025.
The Bottom Line
With interest rates rising, more UK savers are exceeding their tax-free savings limits, leading to unexpected tax bills from HMRC. If you hold more than £3,500 in savings, check your interest earnings, review your tax allowance, and consider tax-efficient savings options like ISAs and Premium Bonds.
With HMRC’s tax notification letters delayed until March 2025, staying ahead of your finances is more important than ever.
