Today on another debacle of a day for the hapless Turnbull Government - we see again the incompetence of the Treasurer on display in a desperate plea to corporate Australia to get out there and back his plan for a company tax cut for big business.

It is a sad spectacle to see the Treasurer realise he is a dud salesman of a dodgy product and to beg the nations CEOs to help him sell his political snake-oil.

Scott Morrison needs to come clean on who paid for his party political 80 page brochure to Australian CEOs? Was it the Liberal Party or was it the taxpayer?

Scott Morrison has spent the last 18 months trying to blackmail Australian CEOs without success into backing his partisan campaign for a $65 billion company tax cut.

This at a time when we also have the remarkable revelation that Liberal backbenchers are now pushing for personal income tax cuts and even for a delay in the Governments company tax cut for big business this despite only recently voting for an income tax hike for low and middle income Australians.

Its clear though that the penny has finally dropped in the Liberal party - theyve worked out that the Prime Minister and Treasurers $65 billion company tax cut is funded by bracket creep and higher taxes on workers.

Morrisons plan is for higher income taxes on workers to help pay for a hand out for big business.

While the Government continues to push for a tax cut for big business, analysis by the PBO shows that average taxes on middle income earners are set to rise to 20+ year highs under this government.

And we know from recent PBO reports that average tax rates are set to rise fastest for people earning just $46,000.

This at a time when wages are growing at record lows and the Government is making things worse because it is increasing personal income tax on every PAYG worker earning more than $21,000 a year via the Medicare levy.

Under Scott Morrisons plan to increase the Medicare Levy, a worker earning $85,000 a year will lose the full benefit of last year's sandwich and milkshake tax cut and actually ends up paying more in income tax.
