Question to the HM Treasury:

To ask the Chancellor of the Exchequer, whether the assessment of the number of estates impacted by the changes to Inheritance Tax on unused pension funds and death benefits (published in the relevant Policy Paper on 21 July 2025) took into consideration the increase in asset values over the coming years.

Most unused pension funds and death benefits payable from a pension will form part of a person’s estate for inheritance tax purposes from 6 April 2027. This removes distortions resulting from changes that have been made to pensions tax policy over the last decade, which have led to some pensions being openly used and marketed as a tax planning vehicle to transfer wealth, rather than as a way to fund retirement. These reforms also remove inconsistencies in the inheritance tax treatment of different types of pensions

The Government will continue to incentivise pension savings for their intended purpose of funding retirement, with ongoing tax reliefs on both contributions into pensions and on the growth of funds held within a pension scheme. Pensions continue to benefit from very significant tax benefits, with gross income tax and National Insurance contributions relief costing £78.2 billion in 2023-24. It is therefore crucial to ensure that tax reliefs on pensions are being used for their intended purpose – to encourage saving for retirement and later life – rather than for passing on wealth free of inheritance tax

Estates will continue to benefit from the normal nil-rate bands, reliefs, and exemptions available. For example, the nil-rate bands mean an estate can pass on up to £1 million with no inheritance tax liability and the general rules mean any transfers, including the payment of death benefits, to a spouse or civil partner are fully exempt from inheritance tax. More than 90 per cent of UK estates will continue to have no inheritance tax liability in 2030-31 following these changes and the reforms will only affect a minority of those with inheritable pension wealth

As is standard practice, the costing and the assessment of the number of estates expected to be impacted by the reforms take account of the forecasts for changes in asset values. For example, pension wealth is grown over time using the equity prices determinant from the Office for Budget Responsibility’s (OBR) economic forecast. The OBR published detailed information on 30 January 2025 and this is available at https://obr.uk/docs/dlm_uploads/IHT-on-pensions-supplementary-release-Jan-2025.pdf.
