ISAs & Taxation

Any and all proceeds from ISAs are exempt from both income and capital gains tax. On death, however, your ISA will form part of your estate and therefore be liable to inheritance tax if your estate exceeds the nil rate band. When you die, if you're married or in a civil partnership, your partner will get a one-off increase in their ISA allowance for that year equivalent to what you had in all ISAs combined, known as an Additional Permitted Subscription (APS), this is calculated regardless of any IHT liability.
