The Australian Federal Government becomes the sole collector of income tax in Australia as State Income Tax is abolished.

The Australian Government, also known as the Commonwealth Government or simply as the federal government, is the national executive government of Australia, a federal parliamentary constitutional monarchy. The executive consists of the prime minister, cabinet ministers and other ministers that currently have the support of a majority of the members of the House of Representatives and also includes the departments and other executive bodies that ministers oversee. The current executive government consists of Anthony Albanese and other ministers of the Australian Labor Party (ALP), in office since the 2022 federal election.

Income tax in Australia is imposed by the federal government on the taxable income of individuals and corporations. State governments have not imposed income taxes since World War II. On individuals, income tax is levied at progressive rates, and at one of two rates for corporations. The income of partnerships and trusts is not taxed directly, but is taxed on its distribution to the partners or beneficiaries. Income tax is the most important source of revenue for government within the Australian taxation system. Income tax is collected on behalf of the federal government by the Australian Taxation Office.
