The Administrative Appeals Tribunal (AAT) has affirmed that two family trusts that were involved in a building and construction business with other related entities were not entitled to a deduction or a capital loss for $4.3 million that they claimed related to a guarantee liability. The AAT found that the documentary evidence and the oral evidence from the relevant trust controllers was not sufficient support for their claim that the guarantee obligation existed. The AAT noted that unusual features of the “guarantee deed” that put into question whether the trusts were genuinely subject to a guarantee obligation – including that the deed did not record any actions that the guarantors were to perform if the debtor defaulted.Important: Clients should not act solely on the basis of the material contained in Update.
