CG76631 | Chattels: sets of assets: special rules
From HM Revenue & Customs · Capital Gains Manual
TCGA92/S262 (4)
CG76577 tells you about the rules which apply when the consideration for the disposal of a chattel (tangible moveable property) doesn’t exceed £6,000.
The £6,000 exemption limit is applied to each disposal of a chattel. This could encourage people to artificially split up a set of articles which is worth more than £6,000 and then sell each asset individually to the same person for £6,000 or less. Each disposal would then be exempt. A set may consist of two or more articles.
If the parts of the set:
were owned by one person at the same time
and
were disposed of by that person (whether on the same or different occasions)
to
one other person acting on their own
or
more than one person acting in concert
or
more than one person who are also connected persons (see CG14580),
then TCGA92/S262(4) treats the separate assets comprising a set as one asset and only one £6,000 limit is allowed
You may come across persons acting in concert, such as a number of dealers acting together as a `ring’ at an auction. If there is no evidence that persons who are not connected have previously agreed to act together to acquire the assets which formed a set, the mere fact that they did so is not sufficient.
CG76632 tells you what is meant by a set.
