Rich Aussies are in for a shock if Labor is elected with the party proposing a minimum 35% income tax on people who earn a salary of over $350,000.
Senior Labor MP Anthony Albanese brought forward the proposal, known as the "Buffet Rule" to the party's national conference on Friday morning.
"This proposal is the creation of a minimum tax rate levied on the total income of high-income earners," said Albanese.
"If adopted, wealthy Australians would continue to spend fortunes on accountants. But once they reached a certain rate - 35% is what was proposed in the United States - no further deductions could be claimed."
The "rule" is named after U.S. billionaire Warren Buffett who proposed adopting a minimum tax rate for high-earners to ensure people didn't avoid paying their fair share.
Albanese cited Australia Institute research which showed more than 75% of Aussies who earn over $1,000,000 didn't pay any tax and that adopting the policy would raise $2.5 billion each year.
The Labor delegates voted to make the policy part of the party platform.
If elected it might cause a backlash against the ALP from Australia's growing number of millionaires who've used accountants to reduce their large tax bills.
