Do I Have to Pay Tax on My Savings UK?

Navigating personal finance in the UK involves understanding how savings are taxed. While earned income taxation is widely known, many individuals may not realize that income generated from their savings can also be subject to UK tax. Effective financial management requires an awareness of these implications. However, various provisions and account types exist within the UK tax system that can significantly reduce or even eliminate this tax liability for many savers. Understanding these rules is important for optimizing your financial position.

Understanding Taxable Savings Income

Income derived from savings is generally subject to UK tax, encompassing various forms of financial gains. Interest earned from most bank accounts, building society accounts, and many National Savings & Investments (NS&I) products is considered taxable income. This includes interest from common savings accounts, fixed-term deposits, and even interest accrued in current accounts. Income from bonds, such as government or company bonds, also falls under the scope of taxable interest.

Dividends received from shares in UK companies or from unit trusts and Open-Ended Investment Companies (OEICs) held outside of tax-efficient structures are also classified as taxable savings income. These are distributions of a company’s profits to its shareholders. While most savings income is potentially taxable, certain sources are explicitly exempt. For instance, winnings from Premium Bonds are entirely tax-free.

Utilizing Tax-Free Savings Accounts

The UK tax system offers specific account types designed to allow individuals to earn income free from UK income tax. Individual Savings Accounts (ISAs) serve as tax-efficient wrappers where interest, dividends, and capital gains are exempt from tax. The annual subscription limit for adult ISAs in the 2025/2026 tax year is £20,000, which can be allocated across different ISA types.

Cash ISAs allow for tax-free interest on cash savings, while Stocks & Shares ISAs enable tax-free growth on investments in the stock market. Lifetime ISAs (LISAs) support saving for a first home or retirement, offering a government bonus on contributions, with a maximum annual contribution of £4,000, which counts towards the overall ISA limit. Junior ISAs (JISAs) provide a tax-free savings environment for children, with a separate annual limit of £9,000.

Premium Bonds, offered by NS&I, represent a unique form of tax-free savings. Instead of earning interest, holders are entered into monthly prize draws where any winnings are completely tax-free. The maximum amount an individual can hold in Premium Bonds is £50,000. Income generated within these specific account types is generally exempt from UK income tax.

Applying Savings Tax Allowances

Beyond tax-free accounts, several allowances can reduce or eliminate tax on otherwise taxable savings income. The Personal Savings Allowance (PSA) permits individuals to earn a certain amount of interest without paying tax. For the 2025/2026 tax year, basic rate taxpayers can earn £1,000 in tax-free interest, while higher rate taxpayers receive a £500 allowance. Additional rate taxpayers do not receive a PSA. This allowance applies to interest from sources like bank accounts and building societies.

The Starting Rate for Savings provides additional tax relief for those with lower non-savings income. For the 2025/2026 tax year, this allowance can shield up to £5,000 of savings interest from tax at a 0% rate. It applies if an individual’s non-savings income (such as wages or pension) is below £17,570. The £5,000 starting rate band reduces by £1 for every £1 of non-savings income earned above the personal allowance.

For dividend income, the Dividend Allowance for the 2025/2026 tax year is £500. This means the first £500 of dividend income is tax-free. Any dividend income exceeding this allowance is then taxed at rates dependent on an individual’s income tax band. These allowances work sequentially: the Personal Allowance is applied first, then the Starting Rate for Savings (if applicable), and finally the Personal Savings Allowance, to determine the taxable portion of savings income.

Reporting Your Savings Income to HMRC

Reporting savings income to HM Revenue and Customs (HMRC) varies by individual circumstances and income earned. Most UK banks and building societies pay interest gross, meaning no tax is deducted at source. These institutions typically provide interest information directly to HMRC.

For employed individuals or those receiving a pension, HMRC often adjusts their Pay As You Earn (PAYE) tax code to collect any tax due on savings interest that exceeds their allowances. HMRC estimates current year interest based on previous figures for this adjustment. If a tax code adjustment is insufficient or taxable savings income is substantial, a different reporting method may be required.

Individuals typically need to complete a Self Assessment tax return if their total income from savings and investments exceeds £10,000 in a tax year, or if they are self-employed. Those already completing a Self Assessment return must include all savings income, even if below the Personal Savings Allowance. Contact HMRC if you believe you owe tax on savings income, ideally by October 5th following the tax year end, to discuss settlement.
