Make tax reform fair: ACTU

Unions want the Turnbull government's tax reform package to tackle the growing inequality and unfairness in the system.

In a new paper released on Tuesday, the ACTU calls for a reduction in generous tax concessions and deductions, such as negative gearing, capital gains tax and the treatment of superannuation that benefits the wealthy.

It wants to introduce a "fair tax contribution" that would ensure rich individuals pay a minimum amount of tax and a greater transparency of tax reporting by companies with an annual turnover of more than $100 million while reducing the complexity of state and federal taxes.

"Our current tax system is simply not fair and needs to be fixed," ACTU president Ged Kearney says.

"There are too many breaks for wealthy individuals and too many loopholes for corporations to get out of paying their share."

She said the last thing Australians want to see is cuts to Medicare, education and other services, so it's important that spending doesn't continue to be diverted into unsustainable, ineffective or unfair tax breaks.
