IHTM33091 | Loss on sale of land: sales excluded from relief: compulsory purchase
From HM Revenue & Customs · Inheritance Tax Manual
Under IHTA84/S197 relief is available where
an interest in land is acquired from the appropriate person
more than three years after the death
by an authority possessing powers of compulsory acquisition.
For a sale made outside the three-year period to qualify for relief it must meet the following conditions:
the interest concerned must be sold:
to an authority that possesses compulsory purchase powers,
following a notice to treat that was served either before or after the death but within the three year period, IHT A84/S197 (1). As long as a notice to treat had been issued it does not matter if the sale was by agreement rather than by compulsory purchase.
the sale results in a loss, IHTA84/S197 (2). In other words, the sale price (IHTM33072), after any adjustments (IHTM33111) is less than the value at the date of death (IHTM33100).
This means that a sale by compulsory purchase outside the three-year period can only increase the amount of provisional relief given. You do not need to include a sale at more than the date of death value and you will not need to keep a case open just in case such a sale takes place.
Under IHTA84/S198 (4) an acquisition under a general vesting declaration (or in Northern Ireland, a vesting order) should be treated in the same way where the operative date (as distinct from the date the declaration or order is made) falls outside the three-year period. This should not be extended to any other form of ‘deemed notice to treat’ such as a ‘blight notice’ served by the owner of property that is adversely affected by planning proposals.
You should refer all claims for relief where there is a compulsory purchase to Technical in the first instance.
