That means, when you die, those pension amounts may face the standard 40 per cent IHT (on amounts above the nil-rate band) just like your house, savings, etc. Currently, many pension pots escape IHT entirely — especially in defined contribution schemes, where leftover funds are not included in the deceased’s estate. Death in service benefits, such as lump sums paid because someone died while employed, from registered pension schemes will remain outside the IHT regime. The Government initially proposed that pension scheme administrators would be responsible for reporting and paying IHT on pensions, but following consultation they have switched course: personal representatives (i.e. executors of the estate) will instead have that duty, and beneficiaries will be jointly liable. Lump sum death benefits, unless excluded (e.g. to spouse, charity), will generally fall into the IHT calculation. The existing exemptions that apply (e.g. transfers to spouse, civil partner, charity) will still apply.
