A significant rise in income tax receipts from pension withdrawals has been attributed largely to retiring baby boomers, according to recent figures from HM Revenue & Customs. The tax revenue from pension withdrawals reached £30.1 billion in the 2024-25 fiscal year, marking a 47 percent increase from the £20.5 billion collected in 2021-22.

This surge reflects the demographic shift as baby boomers—individuals born between 1946 and 1964—begin to retire and draw income from their pension savings through various methods, including annuities, income drawdown, or lump-sum withdrawals. The data also incorporates income from defined benefit schemes, which are common among public sector retirees and provide a guaranteed income in retirement.

Experts note that many baby boomers have benefited from rising property values and tend to hold more valuable defined benefit pensions compared to younger cohorts, who are more likely to have defined contribution schemes. These defined contribution plans depend on accumulated contributions and investment performance rather than fixed payouts.

Frozen tax allowances have further compounded the tax burden for pensioners. The personal allowance—the amount of income one can earn tax-free—has remained at £12,570 since 2021 and is scheduled to stay at this level until at least 2031. Given that the full new state pension for the current year is £12,547 and set to rise slightly next April, this means many pensioners with even a modest additional income will now face income tax liabilities where previously they did not.

David Little, an investment expert at Evelyn Partners, explained that the increase in pension tax revenues is driven by a larger retired population, rising withdrawal amounts amid inflationary pressures, and the impact of static tax thresholds. He also highlighted a growing trend of retirees opting to fully encash small pension pots, despite potentially high tax consequences.

The overall picture suggests a shifting pension landscape as the baby boomer generation retires, with implications for tax policy and retirement planning in the years ahead.
