Govt to trump Labor on taxing super

The Turnbull government is ready to outdo Labor and crack down harder on high-income superannuation tax concessions, it's been reported.

The government plans to raise four times as much as the opposition's policy, Fairfax Media reports.

Labor has promised to cut the income threshold for more heavily taxing contributions from $300,000 to $250,000. The Coalition now plans to cut it to $180,000, Fairfax says.

It says the change, to be unveiled on budget night, will more highly tax the super contributions of an extra 244,000 Australians and will net $2 billion a year, compared with Labor's $500 million a year.
