Carving of the four major banks in Australia due to corporate tax cuts has not achieved crucial crossbench support for the package, despite the fact that legislation has suspended its implementation.
The plan to cut the tax rate for all companies from 30 to 25 percent was given a surprising delay on Tuesday when One Nation leader Pauline Hanson mistakenly missed a vote to kill the bill.
This gave minister Mathias Cormann of Finance the opportunity to try to change the package to exclude the Commonwealth Bank, ANZ, NAB and Westpac.
The government is still hoping for a final job, filibustering to vote in the upper house on Tuesday.
While crossbench senator Derryn Hinch urges the government to support a $ 500 million turnover threshold, he indicates that he would vote in favor of the banks' erosion.
Senator Hanson and her One Nation colleague Peter Georgiou have excluded from supporting the compromise.
"The majority of people do not want these tax cuts for companies with a turnover of more than $ 50 million," Senator Hanson told parliament.
The two senators of Center Alliance are steadfast in their opposition to the tax cuts, despite the changes.
South Australian independent Tim Storer also remains against the package, leaving the government three votes behind the support needed to meet the tax bill.
Senator Cormann called on Labor to support the changes, saying that excluding large donors would make the overall tax plan $ 7.9 billion cheaper by 2027/28.
"When it comes to the big banks, you undoubtedly vote for this amendment and then you vote for the whole legislation," he said.
But Labor Front Banker Doug Cameron compromised and urged the government to take his plan for the next federal election.
"This is not just about the banks, this is about an ideological obsession of this government that, if you simply lower taxes, jobs will be created," Senator Cameron said.
Even if the package failed as expected, Senator Cormann hinted that the government could take the policy to an election.
"If this ends today, there is no doubt that the Australian Parliament will have to visit again soon to protect our economic security in the future," the minister told parliament.
