Anyone earning £50,271 is being warned they are at risk of an HMRC tax bill that many do not expect. Yorkshire Building Society says millions of people earning over that amount are left "confused, anxious and exposed" to unexpected tax bills. This is because of a widespread misunderstanding of the Personal Savings Allowance (PSA).
Frozen Allowance Causes Confusion
Tina Hughes, director of savings at the mutual, said: "Many higher rate taxpayers don't recognise themselves as such. They haven't had a sudden lifestyle change or big pay rise — they've simply been nudged over a frozen threshold. Overnight, their savings allowance is halved, yet our research shows most people don't fully understand what that means."
She added: "People should be able to save with confidence, but instead many are worried about getting it wrong or being hit with a tax bill they weren't expecting."
Staggering Impact on Taxpayers
New analysis of HMRC data and forecasts outlines the staggering impact of this long-ignored policy. By the end of the 2025-26 tax year, taxpayers will have paid over £28 billion in tax on their interest since the PSA was introduced, with £4.7 billion paid at the basic rate. The PSA remains frozen at £1,000 for basic rate taxpayers and £500 for higher rate taxpayers, while additional rate taxpayers still have no allowance at all. Yet during the same period, the Bank of England base rate has rocketed from 0.50% to 3.75%, instantly pushing ordinary savers over their allowances.
How Interest Rates Affect Savers
When the PSA was introduced on 6 April 2016, the majority of easy access accounts paid 1% or less. Now the majority pay 3% or less. This means that in 2016, basic-rate taxpayers would have been able to put away a whopping £100,000 in a typical savings account. In 2026, with interest rates hovering around 3%, savers would only be able to save around £33,000 without breaching their allowance. For those earning over £50,271 and paying higher-rate tax, that amount would fall to around £16,000.
Further Pressure on Savers
From 2027, the Cash ISA allowance will drop from £20,000 to £12,000 for those under 65 — leaving savers with even fewer tax-free options. Combined with a PSA frozen for a decade, the pressures on anyone trying to save responsibly are escalating fast. Hughes added: "Alongside this, the reduction in the Cash ISA allowance for under-65s limits how much people can shield from tax in the first place. This isn't a failure of individuals — it's the result of a system that hasn't kept pace with economic reality and leaves too many people in the dark."
She concluded: "If we want people to build financial confidence, we need modernised savings tax rules and much clearer guidance so people understand their position before they're caught out."
