HMRC Savings Account UK: Tax on Savings Interest, Allowances and Refunds
An HMRC savings account is not an ordinary bank account offered by HM Revenue & Customs. The term usually refers to how HMRC calculates and collects Income Tax on interest earned from UK savings accounts. HMRC also administers Help to Save, a separate government-backed savings scheme for eligible individuals. For the 2026–27 tax year, basic-rate taxpayers can receive up to £1,000 of qualifying savings interest tax-free under the Personal Savings Allowance.
Higher-rate taxpayers receive up to £500, while additional-rate taxpayers receive no Personal Savings Allowance. Taxpayers with lower incomes may qualify for additional tax-free interest through their unused Personal Allowance and the starting rate for savings. Tilly & Cooper explains the HMRC savings tax rules, including reporting requirements, allowances, tax-free savings products, refunds and the announced changes for April 2027.
What Should UK Savers Know About HMRC Savings Accounts?
It does not generally charge Income Tax simply because someone holds money in a savings account.
| Question | Direct answer |
| Does HMRC offer an ordinary savings account? | No; banks and other financial institutions provide ordinary accounts |
| Does HMRC operate Help to Save? | Yes, for eligible people receiving Universal Credit |
| How much interest can a basic-rate taxpayer earn tax-free? | Up to £1,000 under the Personal Savings Allowance |
| What is the higher-rate allowance? | £500 |
| Is Cash ISA interest taxable? | No |
| Is the money deposited in a bank account taxed as income? | Not simply because it is deposited |
| When is Self Assessment generally required for savings interest? | When annual savings interest exceeds £10,000 |
| Can HMRC collect savings Income Tax through PAYE? | Yes, where its collection rules allow |
The main distinction is between the savings balance, the money held in the account, and savings interest, the income generated by that money.
How Does HMRC Calculate Income Tax on Savings Interest?
HMRC calculates savings Income Tax by combining the taxpayer’s taxable savings interest with other relevant income and applying the available allowances and tax bands. Three provisions can reduce the amount payable: unused Personal Allowance, the starting rate for savings, and the Personal Savings Allowance.
How Does the £12,570 Personal Allowance Affect Savings?
The standard Personal Allowance for 2026–27 is £12,570. Any amount not already used by employment, pension or other taxable income may be available against savings interest. For example, someone receiving £10,000 of taxable pension income has £2,570 of unused standard Personal Allowance, assuming no adjustments. This can cover £2,570 of savings interest before considering other savings allowances. The Personal Allowance reduces by £1 for every £2 of adjusted net income above £100,000 and is eliminated at £125,140.
What Is the Personal Savings Allowance for 2026–27?
The Personal Savings Allowance (PSA) is a 0% tax band applying to a defined amount of qualifying savings income.
| Taxpayer’s Income Tax band | Personal Savings Allowance |
| Basic rate | £1,000 |
| Higher rate | £500 |
| Additional rate | £0 |
The applicable allowance depends on the individual’s tax-band calculation, which includes savings income. Scottish taxpayers use UK-wide savings Income Tax rates for savings interest. Scottish employment and pension Income Tax rates are separate.
How Much Tax Is Due on £1,400 of Bank Interest?
A basic-rate taxpayer receiving £1,400 of annual bank interest would generally pay £80 in savings Income Tax if the full £1,000 PSA is available and no other allowance applies.
| Calculation | Amount |
| Annual savings interest | £1,400 |
| Personal Savings Allowance | £1,000 |
| Interest above the allowance | £400 |
| Tax at 20% | £80 |
This example assumes that the interest does not move the taxpayer into a higher Income Tax band.
Who Can Receive an Additional £5,000 of Tax-Free Savings Interest?
The starting rate for savings can provide up to £5,000 of interest taxed at 0% when non-savings income is sufficiently low. For a taxpayer entitled to the standard £12,570 Personal Allowance, each £1 of non-savings income above that allowance reduces the £5,000 starting-rate band by £1. The starting-rate band is fully withdrawn when non-savings income reaches £17,570.
How Is the Starting Rate Worked Out?
Consider an employee with £16,000 annual earnings and £2,000 of savings interest.
| Calculation | Amount |
| Employment income | £16,000 |
| Personal Allowance | £12,570 |
| Employment income above allowance | £3,430 |
| Maximum savings starting-rate band | £5,000 |
| Reduction in starting-rate band | £3,430 |
| Remaining starting-rate band | £1,570 |
The remaining £430 of savings interest can potentially be covered by the individual’s Personal Savings Allowance. Consequently, the £2,000 of interest may be tax-free. This demonstrates that the starting rate and PSA can operate together.
Which Bank Accounts and Savings Products Produce Taxable Interest?
Ordinary savings interest from banks, building societies and credit unions is generally taxable unless an exemption or allowance applies. Interest from fixed-term deposits, certain bonds and qualifying lending arrangements may also be savings income.
| Savings product | Return | General tax treatment |
| Easy-access savings account | Interest | Taxable, subject to allowances |
| Fixed-rate savings account | Interest | Taxable, subject to allowances |
| Building society account | Interest | Taxable, subject to allowances |
| Cash ISA | Interest | Tax-free |
| Premium Bonds | Prizes | Tax-free |
| Help to Save | Government bonus | Tax-free |
Does HMRC Combine Interest From Different Banks?
Yes. Taxable interest earned from multiple accounts is combined when calculating the individual’s savings income. For example, interest of £450 from one bank, £380 from a building society and £520 from another savings account gives total annual interest of £1,350. A basic-rate taxpayer does not receive three separate £1,000 Personal Savings Allowances.
How Does HMRC Treat Joint Savings Accounts?
Interest on a jointly held account is normally divided equally between the account holders for tax purposes. If an account held by two people earns £800 of interest, each would normally be allocated £400. Each person then calculates their tax position separately. A different allocation may be required where the beneficial ownership differs. Evidence of actual ownership should be considered before reporting unequal shares.
When Must You Report Savings Interest to HMRC?
UK banks and building societies normally report customers’ annual interest to HMRC after the tax year ends. HMRC uses that information to calculate possible tax liabilities for taxpayers who do not submit a Self Assessment return. The taxpayer’s reporting obligation depends on annual interest and whether they already complete Self Assessment.
| Situation | HMRC reporting requirement |
| Interest fully covered by available allowances | Usually no separate filing solely for the interest |
| Interest of £10,000 or less, employee or pension recipient | HMRC may calculate and collect tax using provider information and PAYE |
| Annual savings interest above £10,000 | Self Assessment generally required |
| Already registered for Self Assessment | Report savings interest on the return |
| Foreign savings interest | Check overseas income reporting requirements separately |
The £10,000 threshold refers to interest earned during the tax year, not the balance held in a savings account.
What If Your Annual Savings Interest Exceeds £10,000?
You generally need to report savings interest above £10,000 through Self Assessment, even if some or all of the interest may be covered by tax allowances. If you do not already file a tax return, you may need to register for Self Assessment. An individual already filing Self Assessment must report their relevant savings income regardless of whether HMRC receives information directly from the bank. For tax-return preparation and reporting assistance, see Tilly & Cooper’s Self Assessment Tax Returns service.
Can HMRC Collect Savings Tax Through Your PAYE Code?
Yes. HMRC can adjust a PAYE tax code to collect certain savings Income Tax liabilities. HMRC may use information from banks to estimate the current year’s interest or reconcile tax from an earlier year. For example, if HMRC estimates £2,000 of taxable-account interest but your actual interest is significantly lower, the estimated tax adjustment may be excessive.
Which Tax-Free Savings Options Can Reduce Your Interest Tax?
Cash ISAs, Premium Bonds and Help to Save receive different tax treatments from ordinary savings accounts. The suitable choice depends on eligibility, the nature of the return, access requirements and investment risk.
How Does a Cash ISA Exempt Interest From Income Tax?
Interest earned inside a Cash ISA is exempt from UK Income Tax and does not use the Personal Savings Allowance. The overall annual ISA subscription limit for 2026–27 is £20,000. An individual may use eligible ISA products within the annual limit, subject to the applicable account rules. Budget 2026 confirmed that the government would retain the £20,000 Cash ISA subscription limit rather than proceed with its previously planned reduction from April 2027.
Are Premium Bond Prizes Taxable?
No. NS&I Premium Bond prizes are tax-free. Premium Bonds do not pay contractual savings interest. Eligible holdings enter prize draws, and a prize is not guaranteed. The published prize-fund rate should not be interpreted as a guaranteed return for an individual holder.
Is HMRC Help to Save Different From a Normal Bank Account?
Yes. Help to Save is a government-backed savings scheme administered by HMRC for eligible individuals receiving Universal Credit. Eligible account holders can save between £1 and £50 each calendar month under the scheme’s rules. Two government bonuses may be paid over four years, with a potential maximum combined bonus of £1,200. Help to Save bonuses are tax-free.
How Can You Correct Excess Tax Charged on Savings Interest?
The correct procedure depends on whether the overpayment arises from an HMRC PAYE estimate, an incorrect tax calculation or tax deducted directly from savings or investment income. An R40 claim is not the correct method for every savings tax overpayment.
When Should You Correct Your PAYE Code Instead of Using R40?
If HMRC has overestimated the interest used in your current PAYE code, ask HMRC to correct that estimate. Compare the figure in your Personal Tax Account with your bank statements and provide the updated amount. HMRC may issue a revised code, allowing the employer or pension provider to adjust the deductions where the payroll rules permit. For a completed tax year, HMRC may instead issue a reconciliation or refund decision.
Who Can Use Form R40 for a Savings Tax Refund?
Form R40 is intended for eligible individuals claiming back Income Tax deducted from savings and certain investment income. HMRC’s stated eligibility conditions include the following limits:
| Income category | R40 condition |
| Gross savings and investment income | £10,000 or less |
| Gross land and property income | £10,000 or less |
| Net land and property income | £2,500 or less |
| Foreign dividends | Within the tax year’s dividend allowance |
| Registered for Self Assessment | Use Self Assessment instead |
| Living outside the UK | A different claim form or route applies |
HMRC allows R40 claims for the current tax year and the previous four tax years, with a separate application for each year. Ordinary UK bank interest is generally paid without Income Tax being deducted at source. An R40 claim is therefore not automatically appropriate merely because HMRC has collected tax through PAYE.
How Will UK Savings Income Tax Rates Change From April 2027?
Budget 2026 announced higher Income Tax rates for savings income from 6 April 2027. The announced rates are intended to apply throughout the UK. The changes are subject to the further legislation outlined in the Budget.
| Savings Income Tax band | 2026–27 rate | Announced 2027–28 rate |
| Basic | 20% | 24% |
| Higher | 40% | 44% |
| Additional | 45% | 49% |
The government stated that the Personal Savings Allowance and the 0% starting-rate provisions would remain unchanged. For example, a basic-rate taxpayer with £1,500 of savings interest and a full £1,000 PSA would have £500 of taxable interest, assuming no other relief applied. At 20%, the tax would be £100 under the 2026–27 rules. At the announced 24% rate, the equivalent tax would be £120 from 2027–28 if the proposals take effect and the individual’s circumstances remain unchanged.
The increase would therefore be £20 in this illustration. The current Finance Act 2026 contains previously enacted savings rates for 2027–28. Budget 2026 proposes further increases, so the announced 24%, 44% and 49% figures should be described as planned rates until the amending legislation takes effect.
See Budget 2026: Overview of Tax Legislation and Rates.
Frequently Asked Questions About HMRC Savings Interest Tax
No. Holding savings does not itself create an ordinary Income Tax charge. The tax calculation generally concerns interest or other taxable income generated by the account.
Basic-rate taxpayers can normally receive £1,000 under the Personal Savings Allowance, higher-rate taxpayers £500 and additional-rate taxpayers £0. Unused Personal Allowance or the starting rate for savings may also cover interest.
Not simply because your account contains £10,000. The relevant Self Assessment threshold concerns annual savings interest exceeding £10,000, not the account balance.
No. Cash ISA interest is tax-free and is excluded from the Personal Savings Allowance calculation.
Yes, if the mistake results in an actual Income Tax overpayment. HMRC may correct the PAYE code, reconcile the completed tax year or use another refund procedure.
Budget 2026 announced planned savings Income Tax rates of 24%, 44% and 49% from 6 April 2027. The announced changes require further legislation.
