Hon DAVID PARKER (Minister of Revenue): With respect, I think the member has misread the section, because my reading of new section 81A(3) says that "The Commissioner may also backdate any amendment … to the time of when the assessment begins if the recipient of the assessment—(a) is a liable parent, and the backdating has the effect of increasing the amount of the parent's child support liability."—so that's the change in respect of the liable parent, or—"(b) is a receiving carer, and the backdating has the effect of decreasing the amount of child support payable in respect of that carer.", so I think it is reciprocal.
