C4 Corrective Account for IHT

chris_1596

When does a C4 corrective account need to be submitted to HMRC? Does HMRC provide any guidelines on this?

I am definitely no expert in IHT but apparently its within 6 months of discovering that the original was wrong.

Many thanks for the link. The HMRC website seems to suggest that a C4 Corrective Account should be submitted if the original account was defective in any material respect, but I am unclear what that actually means in practice. For example, if the value of an estate changes by just £1, I assume that a C4 isn't then required? But at what point does a change become material? It seems all pretty subjective to me....
