Treasurer Scott Morrison insists the government is rolling out an improved tax system, as key crossbench Senators Derryn Hinch and Tim Storer made broad tax reform a condition for their support for corporate tax cuts.

This week the government shelved laws to reduce corporate tax rates by 25 percent for all businesses over the next decade.

Mr Morrison said the government has made substantial progress in tax reform, and this enterprise tax plan is another part of a broad set of initiatives to grow Australia’s economy.
