HMRC Targets Savers: In recent months, HM Revenue & Customs (HMRC) has sent letters to thousands of savers in the UK who have more than £3,500 in their accounts. These letters warn that their interest earnings may have exceeded the Personal Savings Allowance (PSA) and could be subject to tax. With rising interest rates pushing more savers above the tax-free threshold, many individuals are facing unexpected tax bills. This article breaks down what these HMRC letters mean, how savings tax works, and what you can do to manage your money efficiently while staying tax-compliant.
HMRC Targets Savers
With interest rates rising, millions of UK savers are now exceeding their Personal Savings Allowance, leading HMRC to issue tax letters. If you have received a notification from HMRC—or suspect you may owe tax—check your savings interest, use tax-efficient accounts, and stay informed about tax deadlines.
The key to managing your savings efficiently is being proactive. By regularly reviewing your interest earnings and using tax-free accounts like ISAs and Premium Bonds, you can maximize your returns while staying compliant with HMRC rules.

Aspect | Details |
---|---|
Personal Savings Allowance (PSA) | Basic-rate taxpayers: £1,000 interest tax-free. Higher-rate taxpayers: £500 tax-free. Additional-rate taxpayers: No allowance. |
Rising Interest Rates | Savings accounts now offer interest rates around 5%. A saver with £20,000 at 5% earns £1,000 in interest, hitting the PSA limit for basic-rate taxpayers. |
HMRC Notifications | Letters are being sent to those earning taxable savings interest. P800 tax calculations delayed until March 2025. (Source) |
Tax on Savings | Any interest over the PSA is taxed at 20% for basic-rate taxpayers, 40% for higher-rate, and 45% for additional-rate taxpayers. |
Steps to Manage Tax Liability | Monitor savings interest, use ISAs for tax-free interest, stay informed about HMRC notifications, and consider alternative tax-efficient savings options. |
What is the Personal Savings Allowance (PSA)?
The Personal Savings Allowance (PSA) was introduced in 2016, allowing individuals to earn a certain amount of interest on their savings tax-free. The allowance depends on your income tax band:
- 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.
If your interest earnings exceed your PSA, the excess amount is taxed at your standard income tax rate.
Example of How PSA Works:
- If a basic-rate taxpayer earns £1,200 in savings interest, they will pay 20% tax on the extra £200, which amounts to £40 in tax.
- A higher-rate taxpayer earning £800 in interest will pay 40% tax on £300, totaling £120 in tax.
This is why many savers with balances over £3,500 are being contacted by HMRC—they may be exceeding their tax-free limit due to rising interest rates.
Why HMRC Targets Savers?
Interest rates on savings have increased significantly over the past two years, with many banks offering rates around 5%. This means that savers are now earning more interest than before. For example:
- 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, HMRC has started issuing tax notifications to ensure that individuals report and pay the correct amount of tax on their savings.
Delayed Tax Notifications
Normally, HMRC sends P800 tax calculations by November each year to notify taxpayers of any tax they owe. However, due to an increase in savings interest data, 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’ve received an HMRC letter or suspect you might owe tax, follow these steps:
1. Check Your Bank Statements
Your bank or building society should provide annual statements detailing how much interest you earned. Some banks also include 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. If you exceed the allowance, calculate the tax owed using the following rates:
- Basic rate (20%) – Interest above £1,000 is taxed at 20%.
- Higher rate (40%) – Interest above £500 is taxed at 40%.
- Additional rate (45%) – All interest is taxed at 45%.
4. Wait for HMRC’s Tax Letter
If you exceed your PSA, you may receive a P800 letter or Simple Assessment from HMRC outlining the amount of tax due.
Ways 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 without paying tax on the interest. This is one of the best ways to avoid savings tax legally.
2. Consider Premium Bonds
NS&I Premium Bonds offer tax-free prizes instead of interest. If you’re lucky, you could win prizes while keeping your savings tax-free.
3. Spread Savings Across Family Members
If you have a partner who pays a lower tax rate, consider splitting savings to maximize the tax-free allowance.
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.
