Tell me how to calculate successive charges relief

Successive charges relief, also known as 'quick succession relief', is a relief which reduces the inheritance tax due on an estate where the value of that estate reflects the benefit of property received within the previous five years under a transfer on which tax was payable.

The tax payable on the second transfer is reduced by a percentage of the tax paid on the first transfer. The percentage reduction is on a sliding scale depending on how close together the two transfers were.

Years between the two transfers Percentage reduction

Formula for calculating the relief

Increase in estate / value of the earlier transfer x tax on the earlier transfer x %reduction

Example

Aled died in May 2001 and left a legacy of £100,000 out of his estate of £300,000 to his sister Bronwen. Inheritance tax of £23,200 was paid on the death of Aled.

Bronwen died in July 2005, leaving her whole estate of £400,000 to her daughter Eluned. Inheritance tax is payable on Bronwen's estate. The inheritance tax due on Bronwen's estate will be reduced by successive charges relief.

Calculation

Increase in Bronwen's estate / value of Aled's estate x tax on Aled's estate x 20% = 100,000 / £300,000 x £23,200 x 20% = £1,546.66 successive charges relief

The successive charges relief is limited to the tax due on the second death. For example, if the second transfer is partly exempt because it passes to an exempt beneficiary such as a charity, there may be a smaller amount of tax to pay on the second death than the first death.
