How Inheritance Tax works: thresholds, rules and allowances
Ask HMRC online
Ask HMRC’s digital assistant to get a quick answer to your query about:
- valuing an estate
- paying Inheritance Tax
The digital assistant cannot answer questions about an Inheritance Tax account (IHT400) that has already been sent.
Call HMRC for advice on Inheritance Tax after someone has died. HMRC can help with:
- understanding your Inheritance Tax responsibilities
- confirming the forms you need
- getting paper copies of forms
- completing Inheritance Tax forms
We do not give advice on how to pass on your own property, money, and possessions.
Monday to Friday: 9am to 5pm
Closed on Saturdays, Sundays and bank holidays.
