Deferred consideration: unascertainable: election for treatment of loss - rights - five specified conditions


A right to deferred unascertainable consideration will be within the provisions if it meets all of the following conditions:

  2. the original disposal must have been made in a tax year, “the year of the original disposal”, earlier than the one in which the taxpayer made the disposal of the right, “the year of the right’s disposal”;
  3. where the taxpayer acquired the right as consideration for two or more original disposals, each of those disposals must have been made before the year of the right’s disposal;
  4. the taxpayer must not have acquired the right second-hand, that is it must have been acquired by the taxpayer, with no corresponding disposal, as consideration for the disposal by him of an asset;
  5. the right must be a right to unascertainable consideration as defined in TCGA92/S279B, see CG15089 below.
