Big business has lashed out at Parliament after Treasurer Scott Morrison said he would rather pass a compromised version of his company tax cuts than see the entire package blocked by the Senate.

Business Council of Australia president Catherine Livingstone said abandoning the government's 10-year tax plan would mean Parliament had effectively "given up on Australia's global competitiveness".

As revealed by The Australian Financial Review more than two months ago after the federal election, the government realises it will almost certainly need to split its 10-year plan for corporate tax cuts to win crossbench support.

At this stage that would most likely mean the corporate tax cuts are unlikely to flow to companies with revenues of more than $10 billion, amid signs of support for lowering the tax rate to 27.5 per cent from 30 per cent for companies under that threshold.

Mr Morrison indicated on Thursday that he was focused on getting the package through the Senate, saying where possible he would shoot for "100 per cent of 100 per cent".
