No income tax cuts yet: Morrison

Treasurer Scott Morrison has avoided committing to big personal and company income tax cuts in the next budget.

Asked on Tuesday if he would reward risk takers in the economy through significant cuts to income tax rates, Mr Morrison said other stimulus measures needed to come first.

"We will try and find a way to ensure the earners in our economy get a better deal out of our tax system, but we'll have to start with those areas that are most likely to drive growth," the treasurer told a business summit in Melbourne.
