The 46th Parliament kicked off today with the Morrison government’s income tax plan set as the first bill to be introduced.

The federal government will jump the first hurdle in its bid to cut income tax by securing lower house support using its slim majority.

The $158 million cuts are likely going to come down to winning Jacqui Lambie’s support in the Senate, as it needs four out of six crossbenchers to get the three-stage plan through the upper house.
