Australia’s latest corporate tax transparency report shows that 4,299 large corporate entities paid a combined A$87.5 billion in corporate income tax in 2024–25. The update was published on 1 October 2026 and covers large foreign-owned companies, Australian public entities and Australian-owned private companies.

The Australian Taxation Office said the results continue to reflect high levels of voluntary compliance among large businesses. The small year-on-year reduction in tax paid was mainly linked to lower profitability in the Mining sector following weaker Commodity prices.

Mining Remains the Largest Tax Contributor

The mining industry remained the largest contributor to corporate tax payable in 2024–25.

Lower global commodity prices affected profitability across parts of the sector, but mining still accounted for the largest share of tax paid by large corporates.

The proportion of large corporate entities paying no income tax also fell to 27%, the lowest level since corporate tax transparency reporting began.

The ATO noted that a nil tax result does not automatically indicate non-compliance, as some businesses may legitimately report no income tax payable.

Report Covers 4,299 Corporate Entities

The 2024–25 corporate tax transparency report includes:

  • 1,824 foreign-owned companies with income of A$100 million or more
  • 593 Australian public entities with income of A$100 million or more
  • 1,882 Australian-owned resident private companies with income of A$100 million or more.

Together, these entities paid A$87.5 billion in corporate income tax.

The report also continues to include Australian-owned private entities with total income between A$100 million and A$200 million.

The published information is sourced directly from tax returns and does not include the effect of compliance activity undertaken after lodgment.

Oil and Gas Tax Contribution Reaches A$10.6 Billion

The oil and gas sector paid A$10.6 billion in corporate tax during the year, representing its second-highest contribution since corporate tax transparency reporting began.

The number of entities paying petroleum resource rent tax reached a record 21.

PRRT payable increased by more than 26%, rising from A$1.48 billion in 2023–24 to A$1.87 billion in 2024–25.

The increase followed changes introduced from 1 July 2023 that capped the amount of deductible expenditure available to offset assessable receipts for LNG projects.

Large Business Compliance Remains High

The ATO reported that 94.3% of large business tax was paid voluntarily, increasing to 96.3% after compliance activity.

Since the Tax Avoidance Taskforce was established in 2016, it has secured more than A$36 billion in additional tax revenue from multinational enterprises and large public and private businesses as at 30 June 2026.

The Taskforce focuses on large corporate groups, multinational businesses and high-wealth taxpayers, including arrangements considered to present tax avoidance risks.
