Corporate tax cuts a step closer after gaining One Nation support

Coalition now needs to secure votes from Tim Storer and Derryn Hinch to cut rate from 30% to 25%

The Turnbull government is creeping closer to clinching a deal on its big business tax cuts, with One Nation securing a $60m concession on apprenticeships - but Victoria's Derryn Hinch says he won't make his final position known until next week.

Assuming the support of One Nation's three Senate votes, the government can already count Fraser Anning, Cory Bernardi, David Leyonhjelm and Steve Martin in the yes column - but the Coalition will also need the votes of Hinch and newly sworn-in South Australian senator Tim Storer to pass legislation cutting the corporate rate from 30% to 25% by 2026-27.
