If you die, your ISA will lose its tax-advantaged status and we’ll convert it into a Dealing account. The assets in your former ISA or in any Dealing account will form part of your estate – we’ll distribute them according to the instructions of your executor once probate is granted.
The surviving spouse or civil partner of a deceased ISA holder can inherit their ISA tax benefits. This takes the form of an additional subscription allowance equal to the value of the ISA at the holder’s death and is in addition to the survivor’s own ISA allowance.
Please remember that tax rules can change in the future, and the tax treatment depends on your personal circumstance.
