State and Federal death duties, were abolished Australia in 1970s.
By and large taxing death is mostly accepted as part of life throughout the world (where a lot of planning is put in to trying to minimise or avoid the taxes altogether primarily through the establishment of trusts and divesting wealth offshore).
For example, the amount of duty or tax payable as a result of death in the United Kingdom can be enormous - the current tax rate is 36% of the estate value (subject to adjustments) - so you can well imagine there is whole planning industry dealing with the topic.
Whilst the prospect of a labor government reintroducing death duties was bandied about at the during federal election campaign (almost certainly falsely) I think it safe to say that no government of any persuasion would attempt to reintroduce them at any time in the near future. Just look what happened with Labor’s policy of abolishing franking credits was promptly rebranded “Retiree Tax” the Coalition. And the taxation of discretionary trusts is a real hot potato that seems to have been mashed for now.
There are still taxation consequences for estates and their beneficiaries that should be planned for. Yes, with a little planning you can make your estate a whole lot larger for your loved ones.
