What changes in April 2027

Currently, defined contribution pension pots sit outside your estate for Inheritance Tax purposes. If you die before drawing your pension, your beneficiaries receive the full pot free of IHT. This has made pensions one of the most tax-efficient ways to pass wealth to the next generation.

From April 2027, unused pension pots will be brought into the estate and subject to the standard 40% IHT rate above your combined nil-rate bands. For many people with large pension pots, this represents a substantial new tax liability.

How the NRB and RNRB interact with your pension

Your nil-rate band (£325,000) and residence nil-rate band (up to £175,000 if you leave your home to direct descendants) are applied against the total estate including the pension. If your non-pension estate already exceeds the thresholds, the pension pot is effectively taxed at 40% in full.

The RNRB tapers away for estates above £2 million. If your total estate including the pension pot pushes you over this threshold, you may lose some or all of the RNRB.

Planning considerations before April 2027

There is still time to act before the rules change. Options worth discussing with a financial adviser include: drawing down pension income now and spending or gifting it; using pension funds to pay off debts that would otherwise sit in your estate; reviewing whether your pension nominations still make sense given the new tax treatment; and considering whether gifts made now could reduce the estate within the seven-year gifting rules.

The spouse exemption still applies fully. Leaving your pension to a spouse or civil partner is IHT-free, though their estate will then include it when they die.
