Morrison still aiming for income tax cuts

Treasurer Scott Morrison says if income tax cuts can't be delivered through an increased GST, the government will have to look at other ways.

Federal Treasurer Scott Morrison has left the door ajar to a hike in the GST, linking it to personal income tax cuts

"If that's not possible by that method, we are just going to go the long road," he told 2GB radio in Sydney on Monday.

Amid signs the government is ditching the idea of raising the GST, Mr Morrison said "you just don't write things off carelessly and politically".
