IHTM29123 - Calculating yield – Case has been incorrectly baselined

Example 4

Using example 3, imagine that ERS had been opened before any assessment was raised. ERS has a nil estate value baseline and so works on the basis that all of the IHT threshold is available to use against the amendments.

Simply recording the sub-threshold non-yield changes of £35,000 and the change to PCLT of £50,000 would not be above the “unused” threshold and so no yield would be registered.



Here, we need to adjust the sub threshold changes box to reflect the £255,000 original ‘used’ threshold, as well as the £35,000 non-yield adjustment.


The yield adjustments are

Increase/ Decrease


Sub-threshold changes+ £290,000
Changes to PLCT+£50,000


Yield is calculated as 40% x (£50,000 - £10,000 threshold remaining [£300,000 - £290,000]) = £16,000
