Taxation treatment of your cash payment from MBF
Until the proposed new law is enacted, there is some uncertainty about what amount, if any, should be included in your tax return as a result of the demutualisation. In light of this uncertainty, the Tax Office will allow you to lodge your 2007/2008 tax return without including any capital gain from the receipt of cash from the MBF demutualisation at this stage.
The Tax Office and MBF will let you know what amount (if any) to include in your tax return and how to do this at a later time.
