Australia's current tax system raises over $400 billion annually from major sources like personal and corporate income taxes, consumption taxes including GST and fuel taxes. The federal government collects around 81% of taxes, while states collect 15% and local governments 3%. Compared to other developed nations, Australia relies more heavily on income taxes than social security contributions. While the sources of tax revenue have remained largely the same since the 1950s, the composition has shifted with personal income tax now accounting for 39% of revenue compared to 34% in the 1950s. States and territories raise less own source revenue than they spend on programs like health, education and transport, relying on the federal government for about 45% of their revenue including GST.
