Corporate tax rate across 8 Australasian countries
Across the 7 Australasian countries with a single figure, the corporate tax rate runs from 25% (Fiji) to 30% (Australia). 1 of the 8 carry no single figure; each country page says why. Every figure links to its official source, with the date it took effect and the date we last checked it.
Every figure names the official instrument it came from, the date it takes effect and the date we last checked it against that source. Where no single figure applies, we say so rather than publish one.

1 of these 8 countries carry no single figure for this instrument — the rate is risk-rated, set by the employer, or the instrument fixes no one number. Each says which, on its own page. We do not fill those with an average.
Every value on this page is also available as JSON, with its full citation, revision history and a signed certified extract — see the API.
