UK savers are facing a significant pension tax overhaul from April 2027, with a strict six-month Inheritance Tax (IHT) deadline that could severely impact family inheritances. The government's reform will bring most unused pension pots into IHT for the first time, ending decades of tax-free treatment.
New Rules from April 2027
From April 6, 2027, defined contribution pension funds and certain death benefits will count towards a deceased person's estate. Estates exceeding the £325,000 nil-rate band—or £500,000 with the residence nil-rate band—will incur a 40% IHT charge on the excess. This change, combined with potential Income Tax on withdrawals (up to 45% for higher-rate taxpayers), creates a punishing double-tax hit. Families could lose tens or even hundreds of thousands of pounds on savings built up over a lifetime.
Six-Month Deadline Adds Pressure
The six-month deadline for paying IHT from the date of death intensifies the challenge. Executors must value pensions across multiple providers, handle probate, and settle liabilities swiftly or face mounting interest charges—all while grieving. Des Cooney, a retirement planning specialist at Axis Financial Consultants, warned: “The combination of pension assets becoming subject to inheritance tax alongside income tax on withdrawals is a genuinely significant shift that many people haven't had time to plan around. The six-month deadline for executors is particularly unforgiving — it leaves very little room for families dealing with probate to also navigate the tax implications correctly.”
Practical Challenges and Risks
Pension valuations can be complex and time-consuming, especially with multiple providers or defined benefit schemes. Coordinating payments and ensuring correct allocation of IHT liability from pension assets risks costly errors if rushed. Many families remain unaware of the scale of the changes, leaving them vulnerable to unexpected tax bills during an already stressful period.
Planning Options and Urgent Action Needed
Financial advisers report a sharp rise in concerned clients seeking urgent reviews. Legitimate planning options include carefully managed drawdowns of tax-free cash where suitable, maximising spousal transfers, using surplus income gifting, or placing life cover in trust. Charitable bequests or other IHT-efficient strategies may also help. Mr Cooney warns that one-size-fits-all approaches are dangerous: “Anyone with a defined benefit pension or a sizeable defined contribution pot should be sitting down with a regulated adviser now, not after the deadline has passed. Getting this wrong could mean a family paying far more tax than necessary on wealth that was carefully built up over decades.”
Policy Reversal and Impact
The reforms, first signalled in the Autumn Budget, mark a major policy reversal. Pensions, long viewed as a powerful inheritance tool shielded from IHT, will now form part of taxable estates for most larger pots. While smaller estates may escape impact thanks to nil-rate bands, those with substantial pensions alongside property or investments face significant exposure.
Window for Action Closing Rapidly
With under a year until implementation, the window for action is closing rapidly. Delaying risks not only higher tax liabilities but also administrative chaos for executors struggling to meet the unforgiving six-month timetable. Savers with meaningful pension wealth—particularly those with defined contribution pots exceeding £100,000 or defined benefit entitlements—should seek regulated advice immediately. Early intervention can identify practical steps to protect hard-earned retirement savings and ensure more wealth reaches the next generation.
