Where a herd basis election is in force, the treatment for the purpose of computing farming profits under Case I of Schedule D of the herd or herds covered by the election is governed by the special rules contained in ICTA88/SCH5/PARA3. These rules, which are described in detail in BIM55530 - BIM55560, can be summarised very briefly as follows-
There are further special rules for particular situations. And
the operation of the rules is often complicated by the fact that
many farmers breed their own herd replacements and additions.
A quick reference guide to help determine which rule applies
in a particular situation is provided at
BIM55515.
