Pensions and IHT: the 'double tax' trap

  • From April 2027, most unused pensions and death benefits will fall into estates for IHT purposes. In some cases, inherited pensions may be subject to both inheritance tax (IHT) and income tax.
  • If you pass your estate to a spouse or civil partner, it’s IHT free.
  • There are financial planning opportunities such as gifting, annuities and insurance cover which can help lower the tax burden for your beneficiaries. 

 

For years, pensions have offered a valuable tax advantage alongside retirement income, enabling people to pass on wealth to the next generation. But from April 2027, changes to inheritance tax rules could mean some families face a significantly larger tax bill than they expected.

In some cases, beneficiaries may face both inheritance tax and income tax on inherited pensions – this is known as the ‘double tax trap.’

Who will this impact?

Inheritance tax is charged on estates worth more than £325,000 (the nil band rate). For homeowners, the threshold can rise to £500,000 through the availability of the residence nil-rate band – an extra £175,000 IHT free allowance available when a person’s direct descendants inherit your home.

If your estate (which is likely to include your unused pension from April 2027) exceeds this threshold, your unused pensions may face the 'double tax' trap.

However, if your pension is passed to your spouse, no IHT needs to be paid on the unused funds.

How does the 'double tax' work?

Currently inherited pensions may be subject to income tax in certain situations. For example, if you die aged 75 or over, a large lump sum payment is made. The move to bring them into estates for inheritance purposes from April of next year effectively adds a second layer of tax – IHT.

Let’s look at an example where you die aged 75 or over:

An unused pension of £100,000 (that has pushed the estate above the IHT allowance) would initially face IHT of 40% - £40,000. The remaining £60,000 may then be subject to income tax when the beneficiary withdraws it. The tax rate levied will depend on the income tax band in which the beneficiary’s income currently falls.

As the example demonstrates, beneficiaries can be left with significantly less than the original pension value once both taxes have been applied.
