Companies that are residents of Australia are subject to Australian income tax on their worldwide income. Generally, non-resident companies are subject to Australian income tax on Australian-sourced income only. However, where a company is resident in a country with which Australia has concluded a double taxation agreement (DTA), Australia's right to tax business profits is generally limited to profits attributable to a permanent establishment (PE) in Australia.
All companies are subject to a federal tax rate of 30% on their taxable income, except for ‘small or medium business’ companies, which are subject to a reduced tax rate of 25% for the 2021/22 income year (26% for the 2020/21 income year). The reduced tax rate applies only to those companies that, together with certain 'connected' entities, fall below the aggregated turnover threshold of AUD 50 million.
Integrity measures also ensure that a company will not qualify for the reduced rate unless the specifically defined passive income (including, among other things, interest, rents, and net capital gains) that it derives represents no more than 80% of its total assessable income for the year.
