Many people overlook the planning opportunities offered by pensions because they do not form part of your Estate on death before age 75 and can be left to nominated beneficiaries, usually the Spouse, free of Inheritance Tax.
People assume that no planning is required, but it is the inherited pension wealth that subsequently causes problems, in that it might;
Increase the IHT liability on second death
Not be available to beneficiaries, on second death, until Grant of Probate (perhaps up to two years)
Not reach the second generation if the surviving spouse remarries and pre-deceases the new spouse, or gets divorced with the pension wealth forming part of a settlement.
Prudent planning can avoid these potential problems and further reduce the tax liability on the death of the surviving spouse, allowing the wealth to flow down the generations in a controlled manner, as a part of your legacy.
