Then I pay an additional 15% Division 293 contributions tax on all contributions.
Remember, this is compulsorily paid into super, I have no choice up to the concessional cap.
If we're proposing to tax super at the full marginal income tax rate then no-one in their right mind would put a single solitary cent into it. Why would you? Lock it up until 55/60/65/70yrs old, with all the rule changes that happen every time the government changes. No thanks.
