I see that the model answer has calculated WDA@8% in FY end 31/3/18 on the balance of 3272.
In this example the special rate pool was created with only one motor car in FY end 31/3/17 which was then disposed in FY end 31/3/18 so is it not allowed to create a balancing charge when we know that there is no asset in this pool after the disposal.
I know balancing allowance for mail/special pool is allowed in the year of cessation but is it not allowed in this case when no assets exist in the pool?
It has NOT created a balancing charge as it has been sold for less than tax wdv and hence as you say there can be no balancing allowance until cessation and it is irrelevant whether there are any assets remaining in the pool
