The HMRC is returning over £48.7 million to pensioners who overpaid tax on their pension withdrawals. Nearly 13,000 people who accessed their pensions between April and June 2025 have received refunds, averaging £3,800 each. The overpayments have been primarily caused by HMRC’s use of emergency tax codes, which apply a ‘month one‘ tax rule.
For many pensioners, the surprise tax refunds come after HMRC applied a method of taxing pension withdrawals that often does not account for lump sums. These refunds have drawn attention to the recurring issue of tax miscalculations during pension withdrawals, which can significantly impact retirement plans.
HMRC’s Emergency Tax Code: A Common Cause of Overpayments
When people access their pensions, especially for the first time, HMRC typically uses an emergency tax code. This code treats the initial withdrawal as if it were a regular monthly payment, regardless of whether the individual plans to take out more funds. According to tax experts at Clarkwell & Co., this means a large lump sum could be taxed as if it were a monthly income, resulting in a much higher tax bill than necessary.
For example, if someone withdraws £20,000 from their pension, HMRC may assume they will receive that amount every month, thus applying an emergency code that would classify their income as £240,000 annually. The effect is a much higher tax liability, which can be surprising and distressing for pensioners who were not expecting such a large tax burden.
As a result of these miscalculations, many people are entitled to refunds, sometimes amounting to thousands of pounds. Tax experts emphasise that the issue often goes unnoticed until pensioners file for a refund, making it essential for individuals to check their tax codes and seek advice if they’re unsure about the amounts being deducted.
The Financial Impact on Pensioners
For those affected by this issue, the financial impact can be substantial. According to Helen Morrissey, an expert from Hargreaves Lansdown, HMRC has refunded over £48.7 million in just three months. This has provided a welcome relief to thousands of pensioners, many of whom faced unexpected financial strain due to excessive tax deductions.
The overpaid taxes often arise when pensioners take lump sums from their pensions without realising how they will be taxed. While some recover only a small sum, others are able to claim back over £5,000. These tax refunds highlight a critical issue that could affect retirees’ financial stability. Financial advisors strongly recommend reviewing tax codes carefully when making large withdrawals and ensuring that any adjustments are made promptly to avoid overpayment.
