The people who tried to put it back
After the 2024 Budget left tax-free cash alone, some of the people who had taken it tried to pay it back. A few pension providers had let customers cancel a withdrawal within 30 days, and some savers had counted on that.
HMRC has since ruled this out. Its September 2025 pension schemes newsletter says cancellation rights do not apply to these lump sums, and that the tax consequences of a payment stand even if the money is returned. Paying a large lump sum back into a pension can also break HMRC’s recycling rules, which treat it as an unauthorised payment with tax charges of 55% and in some cases 70%.
How the Treasury has handled cuts before
When the UK has tightened pension tax rules in the past, it has usually protected rights people had already built up.
At A-Day in April 2006, when the pension tax system was rewritten, members whose schemes promised more than 25% tax-free cash kept that higher entitlement. The lifetime allowance, the old cap on how much pension savings could build up before extra tax applied, was cut three times in the 2010s. With every cut, savers could register a form of protection to keep the old, higher limit, and people who did so still have a higher tax-free cash limit today, more than two years after the allowance was abolished.
A government short of money could break that pattern on Wednesday, but if it holds, savers who wait would be likely to keep the tax-free cash they have already built up, and their money would stay invested inside the pension in the meantime.
The frozen cap
Unless they have registered protection, the most tax-free cash anyone can take across all their pensions is £268,275. That figure is 25% of the final lifetime allowance of £1,073,100, which applied from April 2020 until the allowance was abolished in 2024, and the cap has stayed at that level since 2020.
UK prices have risen by about 33% since April 2020. In April 2020 money, the cap is now worth about £202,000, and if it had kept pace with inflation it would stand at roughly £356,000. The cap only affects pensions worth more than about £1.07m, and for those savers the tax-free cash available has shrunk in real terms every year since 2020.
