Versions of s. 143.4(6)

If a taxpayer, or another taxpayer that does not deal at arm’s length with the taxpayer, has a right to reduce an amount in respect of an expenditure of the taxpayer in a taxation year that is after the taxation year in which the expenditure otherwise occurred, determined without reference to subsection (3), the taxpayer is deemed to have the right to reduce in the taxation year in which that expenditure otherwise occurred if it is reasonable to conclude having regard to all the circumstances that one of the purposes for having the right to reduce after the end of the year in which the expenditure otherwise occurred was to avoid the application of subsection (2) to the amount of the expenditure.
