Australia evaluates resource tax reforms and capital gains changes

Australia is facing significant shifts in its taxation landscape, involving both resource extraction and capital gains. A new report suggests the country could collect an additional A$45 billion annually from its mining, oil, and gas sectors. This potential revenue includes approximately A$28 billion from minerals such as iron ore, coal, gold, copper, and lithium, alongside A$16 billion to A$18 billion from petroleum and liquefied natural gas. The analysis argues that current flat royalty structures fail to capture sufficient revenue during commodity price surges, citing Queensland’s progressive coal royalty system as a successful model.

Separately, reforms to the capital gains tax and negative gearing are set to take effect in July 2027. The existing 50 percent discount will be replaced by a system where sellers subtract inflation from gains and pay a minimum rate of 30 percent on the remaining amount. To manage the transition, assets held on June 30, 2027, will be deemed reacquired at market value to establish a boundary between pre-transition and post-transition gains. Treasury has proposed an apportionment method for assets without readily ascertainable market values, using a constant compound growth rate to estimate transition values.
