What is the IHT nil-rate band?

Every individual has a nil-rate band (NRB) of £325,000 — the portion of the estate that is exempt from IHT. Unused NRB can be transferred to a surviving spouse.

What is the residence nil-rate band?

The RNRB is an additional £175,000 allowance available when a main residence is passed to direct descendants (children or grandchildren). Combined with the NRB, a couple can shelter up to £1 million.

Are gifts made before death subject to IHT?

Chargeable gifts made within 7 years of death use up the nil-rate band first. Gifts to individuals are exempt after 7 years (potentially exempt transfers, or PETs).
