HMRC estimates that the UK tax “gap” from unpaid taxes reaches £59.2 billion in the 2024-25 tax year, according to figures reported by multiple outlets. The tax gap is described as the difference between the amount of tax that should be paid and what is actually paid on time. For 2024-25, the tax gap is estimated at 6.4%, which is higher than the year before, indicating an increase in the share of taxes not collected as expected. The figures reflect HMRC’s assessment of underpayment and non-payment across the tax system. While the reported numbers do not break down the tax gap by category in the provided summaries, they establish both an overall monetary estimate and a percentage measure for the period. Overall, the reporting is consistent that 2024-25 shows a larger estimated shortfall than the preceding year, based on HMRC’s published modelling and calculations.
