Legislative Council Fifty-Fourth Parliament, First Session (54-1) 54 1 Parliament of South Australia Legislative Council published Question Time Land Tax Land Tax The Hon. I. PNEVMATIKOS Legislative Council Land Tax The Hon. I. PNEVMATIKOS (15:18): Supplementary question arising from the original answer: whilst I appreciate some details have been provided, when and how are full details going to be provided about the modelling? The Hon. R.I. LUCAS Legislative Council Land Tax The Hon. R.I. LUCAS (Treasurer) (15:18): The details have been provided. It is simply impossible—the only way the precise nature of the calculations in terms of the modelling can be released would be to release the full confidential taxpayer database of RevenueSA because the modelling necessarily requires individual consideration of the confidential tax information of individuals, companies and trusts in South Australia. What the honourable member is asking for is to release all of that sort of detail and that's unlawful, but it would also be improper and wrong to release that sort of information. The modelling and the methodology that the Treasury has used has been stress tested by a reputable, independent group such as PwC and, as I said, in excruciating detail they have outlined how that methodology was conducted. But it is unlawful to release confidential details about the individual taxpayer information that has to be used by Treasury, or RevenueSA in particular, in terms of doing the precise calculations of the impacts on individuals and particular groups.
