Changes due to coronavirus (COVID-19) measures
Due to measures put in place to stop the spread of coronavirus (COVID-19) HMRC has changed the way they deal with Inheritance Tax.
Until further notice, HMRC will accept forms IHT400 that are not physically signed from both professional agents and unrepresented taxpayers.
We will accept the forms from professional agents if:
- the names and personal details of the legal personal representatives are shown on the declaration page
- the account has been seen by all the legal personal representatives and they all agree to be bound by the declaration
The agent must include the following statement:
‘As the agent acting on their behalf, I confirm that all the people whose names appear on the declaration page of this Inheritance Tax account have seen the Inheritance Tax account and agreed to be bound by the declaration on page 14 of the IHT400’.
We will accept the forms from executors or administrators acting without the help of a professional agent if:
- the names and personal details of any other executors or administrators are shown on the declaration page
- the account has been seen by all the executors or administrators and they all agree to be bound by the declaration
Where there is more than one person acting for the estate you must include the following statement:
‘As a legal personal representative acting for the estate, I confirm that all the people whose names appear on the declaration page of this Inheritance Tax account have seen the Inheritance Tax account and agreed to be bound by the declaration on page 14 of the IHT400’.
Use form IHT400 and supporting notes and the schedules IHT401 to IHT436 listed below as part of the probate or confirmation process if there’s Inheritance Tax to pay, or the deceased’s estate does not qualify as an ‘excepted estate’.
