Savers in the UK risk unexpected tax bills on their interest earnings if they overlook key rules, according to recent analysis. Tax kicks in on savings interest exceeding £1,000 annually for most individuals.
Upcoming Tax Rate Changes
Starting in April 2027, the tax rate on savings income rises by two percentage points. Basic rate taxpayers will face 22% on taxable interest, up from 20%. Higher rate taxpayers see their rate increase from 40% to 42%, while additional rate taxpayers will pay 47% instead of 45%.
Understanding Personal Savings Allowance
The personal savings allowance lets basic rate taxpayers earn up to £1,000 in interest tax-free each year. Higher rate taxpayers receive £500, and additional rate taxpayers get no allowance. A survey by Leeds Building Society reveals that one in four people misunderstand this allowance.
Catherine Wray, senior savings manager at Leeds Building Society, stated: “Understanding personal savings allowances and savings tax requirements can be difficult. There is a notable proportion of savers, almost one in ten, who are not confident in their understanding of personal savings allowances and are likely to require additional support.”
She added: “That’s why we would encourage anyone who is confused about their own savings allowance to speak to a colleague about reviewing their savings, or to read up about the rules and upcoming changes online. We want to help people to become more financially resilient. That means encouraging good savings habits and helping people to understand the best options to suit their individual circumstances.”
