How long does it take HMRC to process IHT400 form?

Question: My father died recently with an estate worth over the IHT threshold of £325,000. I have completed the IHT400 form and sent it  HMRC. When can I expect to hear back from them?

Answer: It varies! HMRC should take no more than 20 (working) days to get back you. But in simple cases they can sometimes be much quicker. Sometimes they can get back you within just a few days!
