Calculate the additional threshold for the estate of someone who has died

Calculate the additional threshold for the estate of someone who has died using details from:

  • an IHT400 account form with the value of what’s in the estate already worked out
  • a paper schedule IHT435 if you have already started filling one in
  • a completed schedule IHT436 if you are transferring any unused home threshold

You will also need details of the property if there is any additional threshold because the person who died downsized or sold that home.
