CGT base cost of ISA investments 3 years post death

I have posted previously regarding the base cost of inherited ISA investments and note the override of the ‘usual’ rule provided by Reg 34A SI 1998/1870.

I am dealing with a similar case whereby an estate includes an ISA portfolio of shares. We are now more than 3 years post death and the estate remains in administration (largely due to an uncooperative executor and the need for a Court order to remove them). The intention is to liquidate the ISA portfolio which is standing at a significant gain. I am unclear as to the relevant base cost and would appreciate views please - presumably this is either the date of death value, or the value at the 3rd anniversary of the death of the deceased when the ISA treatment ceased?

Hi Kelly,

The ISA provider will usually close the ISA 3 years and 1 day after death. (If no transfer or encashed to the executor).

To this point it grows tax free. After the 3 years its non-Isa and will be subject to CGT as any other asset of the estate.

The base cost will be the value the ISA is converted.
