Could your savings generate a tax bill?
Most individuals can earn interest from their savings without incurring a tax liability thanks to a number of allowances available each tax year (from 6 April to 5 April). These include your Personal Allowance, the starting rate for savings, and the Personal Savings Allowance, with the amount you receive depending on your other income.
Your Personal Allowance can cover tax-free interest if not fully used by wages, pension, or other income. You may also qualify for a starting rate for savings of up to £5,000, which is tax-free. This rate is reduced by £1 for every £1 of other income above your Personal Allowance, and you are ineligible if your other income is £17,570 or more.
The Personal Savings Allowance can also result in some or all of the interest you receive being tax-free. The amount covered by the allowance depends on your Income Tax band. For example, taxpayers can receive up to £1,000 of interest tax-free and higher rate taxpayers up to £500 tax-free, whilst additional rate taxpayers have no allowance. To determine your applicable band, add all interest received to your other income.
If your total savings interest exceeds these allowances, the excess is taxed at your usual Income Tax rate. For employed individuals or pensioners, HMRC typically adjusts your tax code based on previous year's interest. Self-employed individuals must report savings interest on their self-assessment tax return and should register for self-assessment if their income from savings and investments exceeds £10,000.
If you have overpaid tax on savings interest, you can reclaim it within 4 years of the relevant tax year-end, either via self-assessment or by claiming a refund if you do not file a return.
