150,000 married ISA savers die every year. Under old rules, their ISA wrapper and the tax advantages ceased on death.

Since 6 April 2015, surviving spouses or civil partners who died after 3 December 2014 can pass their ISA pot in its entirety to their spouse or partner with the tax advantages.

This has substantial tax benefits for the surviving spouse or civil partner.

It is also possible now to hold assets that qualify for business property relief in an ISA wrapper, which can be used for inheritance tax planning.
