Tax cuts 'when we can': Morrison

It's not as definite as just a few months ago but Treasurer Scott Morrison says the government will cut personal income tax when it can.

Back in January Mr Morrison was "quite passionate" about delivering tax cuts to address bracket creep - which will push middle-income earners into a higher tax bracket just through wage inflation - but that now appears less immediate.

"It's important to reduce the tax burden on Australians and we will do that wherever we can," the treasurer told parliament on Wednesday.
