BIM55590 | Farming: herd basis: class of herd
From HM Revenue & Customs · Business Income Manual
S112(1)(c), S124(1) Income Tax (Trading and Other Income) Act 2005, S110(1)(c), S122(1) Corporation Tax Act 2009
A herd basis election must specify the class of herd to which it relates, and will then apply to all herds of that class kept by the farmer making the election. A separate election is necessary for each class.
Herds are regarded as of the same class if:
the animals in them are of the same species (irrespective of breed), and
the products for the sake of which they are kept are of the same kind.
For example, if a farmer has two dairy herds, one Friesian and the other Ayrshire, both are of the same class and would be covered by a single election, so both would have to be dealt with in the same way. But if a farmer has a dairy herd (producing milk) and a beef suckler herd (producing beef calves), they fall into separate classes as the products for the sake of which they are kept are different. Thus a separate election would be needed for each herd and the farmer could choose to make an election for one herd but not the other.
Where there is a change in the purpose for which a herd is kept, see BIM55615.
