You may like to refer to your trust deed or the person whom helped you draw up your deed to determine what to insert under 'Beneficiary of the Trust'. Please talk to your advisor in regard to which TFN you need to apply. You only need to provide your Tax File Number (TFN), TFN exemption code when applying for a Commonwealth Direct Investment Account (CDIA). It is not mandatory however if you do not provide us with one of these, we are required by law to withhold tax from any interest paid on your CDIA at the highest marginal tax rate plus the Medicare Levy.
