What IHT408 is for — and when you don't need it
IHT408 exists for one specific moment: the goods have already passed to individual beneficiaries under the will or intestacy, and those beneficiaries — not the deceased — decide to give some or all of them to charity.
The two things IHT408 does at once
It lets beneficiaries formally donate inherited household and personal goods to a UK charity, and — in the same step — claim inheritance tax exemption on their value against the estate.
Without this form, the same result would need a formal, solicitor-drawn deed of variation.
The distinction that matters most: whose decision was it?
If the deceased's own will left specific goods, or a share of goods, directly to a charity, that already gets ordinary charity exemption automatically — IHT408 is not needed and should not be used for it.
IHT408 is only for goods that reached individual people first, who then chose to pass them on.
What 'household and personal goods' covers
Everyday chattels — furniture, clothing, kitchen items, ornaments, and similar personal possessions.
It is not the route for cash, land, shares, or business interests being redirected to charity; those use the general instrument-of-variation or other exemption routes instead.
