Frequently Asked Questions (UK IHT)

Under the 2025/2026 IHT reforms, if an individual who was UK tax resident for 10-20 years leaves the UK, their worldwide estate remains subject to UK IHT for a 'tail' period of 3 to 10 years depending on how long they were resident.

Transfers between married spouses or civil partners are 100% exempt from UK IHT, regardless of value, provided both spouses are UK tax resident.
