Jim Chalmers is set to open up discussions on potential tax changes at the government's economic reform summit in August, emphasizing Labor's responsibility to plan for the future.

Seeking a new approach to policy-making amidst uncertainty about the government's post-election plans, Mr. Chalmers will encourage the public to propose innovative tax reform ideas.

During a National Press Club address, the treasurer highlighted the importance of tax reform in achieving economic goals such as enhancing productivity, ensuring budget sustainability, and improving economic resilience.

Business groups have welcomed the roundtable opportunity, although concerns remain following the previous "jobs and skills summit" dominated by unions.

Mr. Chalmers will discuss the government's past actions on budget pressures and emphasize the need for further reforms, including potential changes to income taxes, company taxes, and areas like electric vehicle taxes.

The upcoming roundtable will allow participants to freely share ideas and concerns without non-disclosure agreements, focusing on productivity, budget sustainability, and economic resilience.

Mr. Chalmers will stress the importance of addressing global volatility and meeting the needs of working people to rebuild confidence in democratic politics and economic institutions.

Highlighting the government's duty to go beyond election promises, Mr. Chalmers aims to shift the focus of the second term towards productivity reform.

The planned productivity gathering, announced by the prime minister, will bring together unions, businesses, and interest groups to work towards a common goal.
