“The government expects the changes to bring in an extra $2 billion a year, however, this fails to take into consideration what will happen if people start to change their approach to superannuation,” she said.

“It’s not unrealistic that of the 80,000 people expected to be impacted by these proposed measures, those who can, will shift their superannuation balances to different structures and taxation environments resulting in reduced government revenue in years to come.”

Randeria said it then makes the proposed changes a finite tax and the government will face yet another budget hole in the future.

However, she said two other options would not only allow the government to generate increased revenue that is sustainable over the longer term but also ensure the system is truly equitable.

The first is to increase the tax rate on super by just 1 or 2 per cent, which would still offer a concessional tax environment that is lower than the marginal tax rate and would have no impact on people’s current standard of living.

The second option is to increase the rate or to expand the reach of GST, which has remained unchanged for decades.

“Implementing either of the above changes would allow the government to collect increased revenue well into the future, and importantly, would spread the burden across all Australians, rather than the current argument of pitting the ‘rich’ against the ‘poor’,” Randeria said.

“Such changes would also provide extra flexibility for the government to potentially reduce personal income tax, or use the consistently increased revenue to fund infrastructure, innovation, health, and the like.”

Randeria said these suggestions aren’t “radical” and were recommended by the International Monetary Fund for making better use of indirect taxation.

“I believe that ignoring sound economic advice to push ahead with the proposed changes to superannuation will not only result in lower-than-expected revenues in years to come, but the government will find itself with increased spending on the Age Pension, as people will no longer be encouraged to be self-sufficient in retirement,” she said.

“And should both those predictions come to fruition, we should all be concerned about what changes the Government will consider next.”
