Government pushes on with company tax cuts

Labor has tried to stymie the federal government's push to slash the tax rate for Australia's biggest businesses, saying the country cannot afford it.

Treasurer Scott Morrison has introduced to parliament the second part of his 10-year company tax cut plan, applying to those turning over more than $50 million.

It comes two days after MPs rubber-stamped the first tranche, which lowers the rate from 30 per cent to 27.5 per cent for businesses earning up to $50 million over the next three years.

"We can't afford to stop there," Mr Morrison told the lower house on Thursday.

"This government will not rest until we have successfully fought to implement a company tax framework that sets Australia up to have more and better-paid jobs in the future and for future generations."

Opposition frontbencher Tony Burke said the latest budget showed the second stage of tax cuts were not affordable.

He unsuccessfully tried to move the legislation not be dealt with until August 2019.

The plan to cut to company taxes was the centrepiece of the 2016 budget but had to be split in two after the Senate rejected the full package.
