"So non-concessional contribution caps could become even more modest. Once upon a time, if you weren't making a deduction, effectively it was an unlimited amount that you could put into super. From 2007, it went down to $150,000, then jumped up again to the $180,000, now of course it's at $100,000 and it might go down even lower, to $75,000," said Mr Figot.

"The strategic implication of this is that if you have a client who wants to put money in super, then perhaps put it in sooner rather than later."

Mr Figot pointed out that tossing in the entire $300,000 allowed under the bring-forward rule may not actually be the best approach to making the most of the caps.

"If you want to max out the non-concessional caps then you want to contribute $100,000 now and then wait until the new financial year and put in another $300,000."

Mr Figot said while this may seem obvious to a lot of SMSF practitioners, advisers often do make this mistake.
