In the straightforward case the relief operates by replacing the
value on death (
IHTM33100) by the sale price (
IHTM33072).
But there are special rules that adjust the sale price
These adjustments provide the sale value (
IHTM33073) on which the relief is
based.
Any adjustment to the sale price and the resulting revised
date of death values will need to be notified to the tax office (
IHTM33046) when a claim is made more
than 3 years after the death or if the tax office approaches you
for information regarding a claim for relief.
