“There have not been any untoward changes which has been good,” said Mr Mackay.

Mr Mackay said SMSF trustees and those working in the SMSF industry are probably pleased with the current stability of the system.

“2014 has been the first year in ages where we’ve had that certainty from government that there wouldn’t be any untoward changes,” he said.

Mr Mackay said clients have been able to make longer-term decisions based on that certainty.

Superannuation, he said, requires making long-term decisions so an “environment that fosters stability and certainty is better for planning for retirement”.

“The system [is] working quite well now, there are some things that we’ve tightened up such as excess contributions, there are still potentially some elements that need tidying up but by and large if we can keep the stability of the system so that investors can make informed decisions, that will make the system stronger,” said Mr Mackay.

“The fewer changes we can make, the better for the system, and the better for investors.”

Mr Mackay has previously hit out at the “incessant tinkering” with superannuation, labelling it a blow to investor confidence.
