Business wants a possible company tax cut funded by reduced government spending and not by shifting the corporate tax burden.
Prime Minister Julia Gillard told her economic forum that achieving a company tax cut was the "absolute top priority" of the government's business tax working group.
However, the Australian Chamber of Commerce and Industry is not impressed.
"We don't believe the function of working out how to fund that should be sub-contracted to a community," the chamber's director of economics and industry policy, Greg Evans, told ABC Radio on Thursday.
Nor does the chamber back the government's plan to fund any tax cut with other changes in the business tax system.
"We think that should be through funding savings," Mr Evans said.The chamber believes the tax system needs reforms that improve the international competitiveness of Australian companies.
