Form IHT4 must be issued with each calculation you send.
This is a schedule of various important details about Inheritance Tax calculations for the taxpayer, including “how to pay” and interest charges.
The IHT4 will replace page 2 of the calculation and will be
printed by Compass.
You must print and attach a form IHT4 to a calculation even
if you know you have previously sent one with earlier calculations
to the same person.
