Pension savers face a significant financial blow, with retirement funds set to be caught in a punishing "double tax" trap from next April.
The changes, first unveiled by Chancellor Rachel Reeves in her October 2024 Budget, will bring unused pension assets within the scope of inheritance tax for the first time.
This represents a dramatic departure from the current system, where unspent pension pots can be passed to loved ones without attracting IHT.
With less than twelve months until the new rules take effect, financial experts are urging savers to act swiftly.
Jason Hollands, Managing Director at wealth management firm Evelyn Partners, said: "April 2027 may feel some way off, but when it comes to financial planning, a year is not a long time. The changes on the horizon are significant and, for many people, will require a rethink of strategies that may have been in place for many years.
"Under the new rules which are set to go ahead next April, that benefit will be materially reduced, and in some cases, families could face a double layer of taxation."
Previously regarded as one of the most tax-efficient vehicles for transferring wealth between generations, defined contribution schemes will lose much of their appeal as inheritance planning tools.
The tax treatment becomes particularly punishing when the pension holder dies after reaching 75, as beneficiaries must then pay income tax at their marginal rate on any withdrawals from the inherited pot.
For those in higher or additional rate tax brackets, this creates the prospect of extremely steep effective tax rates on inherited pension wealth.
The Government's own projections indicate that 10,500 estates will face inheritance tax bills for the first time in the 2027-28 tax year
Ms Hollands commented: "For years, money-purchase pensions have been a cornerstone of estate planning because they could typically be passed on free of inheritance tax.
"The ability to leave an unspent pension pot to your loved ones tax free has been one of the few perks of having a defined contribution pension fund rather than a final salary defined benefit scheme where the risk sits on the shoulders of your employer."
The Government's own projections indicate that 10,500 estates will face inheritance tax bills for the first time in the 2027-28 tax year as a direct result of these pension changes.
A further 38,500 estates already liable for IHT will see their bills rise, with the average increase estimated at around £34,000.
