For decades, defined contribution (DC) pension funds held in trust have sat outside the taxable estate for IHT purposes, making them one of the most powerful — and widely used — tools in intergenerational wealth planning. Unspent pension pots could be passed to beneficiaries largely free of IHT, and if the pension holder died before age 75, free of income tax too. This combination made pensions an exceptionally tax-efficient vehicle for passing on wealth to the next generation.
That is set to change dramatically. From April 2027, HMRC has proposed bringing unspent pension funds into the deceased's estate for IHT purposes. This means that pension pots — previously a tax shelter — will be subject to the same 40% IHT as the rest of the estate, on top of any income tax payable by beneficiaries when they eventually draw on the funds. For many individuals with substantial pension savings, this represents a fundamental shift in estate planning strategy.
Under the current rules (before April 2027), a pension pot held in a registered DC scheme with a nominated beneficiary is treated as a trust asset, outside the estate for IHT purposes. If the pension holder dies before age 75, the pot can be paid to beneficiaries completely free of all tax. After age 75, beneficiaries pay income tax on drawings at their marginal rate, but no IHT is charged on the pot itself. This has made pensions the preferred vehicle for retaining wealth — spending other assets first and leaving the pension untouched wherever possible.
Under the proposed April 2027 rules, the pension pot will be included in the estate for IHT purposes and will be subject to 40% tax on any amount above the available nil-rate band. Beneficiaries will also continue to pay income tax on drawdowns (marginal rate if death is after 75). The combined tax burden — IHT at 40% on the pot, followed by income tax at 40% or 45% on the residual — could reduce a large pension to less than a third of its value in the hands of higher-rate taxpayer beneficiaries.
This Pension Inheritance Tax Calculator models both the current rules and the proposed 2027 rules side by side, allowing you to see exactly how much additional tax the new regime would impose on your pension pot — and to begin planning accordingly. Key strategies to consider include drawing down from pensions earlier, making larger lifetime gifts, or re-evaluating whether to use pension savings for living expenses while preserving other liquid assets for inheritance.
The calculator models two tax regimes for comparison:
A large 'Additional Tax Under 2027 Rules' figure signals an urgent need to review your pension drawdown strategy and estate plan. Consider increasing pension withdrawals now (especially within the basic-rate tax band), using drawn pension funds for lifetime gifts, or restructuring other assets. Speak to a pension specialist and IHT solicitor — the interaction between income tax relief on pension contributions and IHT at death makes this one of the most complex areas of personal tax planning.

Currently, IHT on non-pension estate = £40,000; income tax on £500,000 pension = £200,000. Total: £240,000. Under 2027 rules, IHT on pension = £200,000; income tax on remaining £300,000 = £120,000; plus estate IHT £40,000. Total: £360,000 — an additional £120,000 tax burden.

Under current rules: death before 75 means zero income tax on pension, and the combined estate is within the NRB — zero total tax. Under 2027 rules: £120,000 IHT on pension plus £56,000 income tax on the residual. A £176,000 tax liability from nothing.
Defined contribution pension funds are held in trust by the pension provider, with the member only having a nominee right to direct who receives the funds. Because the member does not legally own the assets in the same way as a bank account or property, the pension was historically excluded from the estate. The proposed 2027 change would override this treatment by inserting a specific IHT charge at death.
Defined benefit (final salary) pensions typically pay a lump sum or spouse's pension on death, rather than passing a pot to beneficiaries. The proposed changes primarily affect defined contribution pensions with remaining uncrystallised or drawdown funds. The treatment of DB scheme death benefits depends on the specific scheme rules and is generally not affected by the proposed IHT reform.
Crystallised funds are those that have been designated for drawdown — where the pension has been moved into income drawdown (flexi-access drawdown). Uncrystallised funds are pots not yet in drawdown. Under current rules, both types are generally outside the IHT estate when held in a registered scheme. The proposed 2027 changes would apply to both crystallised and uncrystallised DC funds.
Under the proposed rules, dying before 75 would no longer protect pension funds from IHT — the pot would still be included in the estate for IHT purposes. The only remaining benefit of dying before 75 is that beneficiaries would still receive pension drawdowns free of income tax (a significant but partial advantage).
This depends on your overall tax position. Drawing pension income now increases your current income tax liability but reduces the IHT exposure in future. If your marginal income tax rate is lower now than the IHT rate (40%) you would pay later, drawing down and gifting or investing may be efficient. A detailed cash-flow analysis with a financial planner is essential.
Yes — nominations remain important for ensuring the pension bypasses probate and reaches the intended beneficiaries quickly. Even if IHT applies to the pot, having a valid nomination on file means the pension trustees can pay the funds directly without waiting for grant of probate. This avoids delays and ensures the beneficiary receives the residual funds (after IHT) promptly.
If a pension holder dies after 75 under the proposed 2027 rules, the pension pot first suffers 40% IHT, then beneficiaries pay income tax on withdrawals at their marginal rate (potentially 40% or 45%). On a £1,000,000 pension: £400,000 IHT leaves £600,000, on which a 40% taxpayer would pay £240,000 income tax — leaving £360,000. The effective combined rate is 64%, representing significant double-taxation. HMRC has proposed an offset mechanism to partly address this, but details are still being finalised.
Some specialist trust-based pension arrangements and relevant life policies may retain IHT-exempt status — this remains under legal and political challenge. Small self-administered schemes (SSAS) and self-invested personal pensions (SIPPs) will likely be subject to the new rules. Enterprise Investment Scheme (EIS) and other tax-advantaged investments outside pensions may offer alternative IHT-efficient vehicles worth exploring with a specialist adviser.
