The Australian Taxation Office (ATO) has today published its annual corporate tax transparency (CTT) report which reveals that the 4,299 entities paid a combined $87.5 billion in 2024–25.
ATO Acting Deputy Commissioner Michelle Sams said the tax revenues from this demographic are inherently linked to broader economic trends. The results continue to reflect strong levels of voluntary compliance. The small year on year reduction in tax paid is predominantly due to reduced profitability of miners flowing from lower commodity prices. The effectiveness of ongoing investment in the Tax Avoidance Taskforce over many years has also ensured large businesses pay the right amount of tax.
‘Australia remains a world leader for large business tax compliance, supported by high levels of transparency and the ATO's dedicated large market compliance programs.’
‘The majority of Australia’s largest companies are paying the right amount of tax and meeting their tax obligations. We continue to take firm action where we identify non-compliance,’ Ms Sams said.
The mining industry remains the largest contributor to tax payable, despite weaker global commodity prices which impacted profitability.
‘The proportion of large corporates paying no income tax also dropped to 27% in 2024–25 – the lowest level since CTT reporting began. This in part reflects the continued effort of the Taskforce to hold large business to account.
‘It’s important to remember that a nil tax result doesn’t automatically imply wrongdoing. Many large businesses legitimately pay no income tax but we continue to scrutinise these outcomes closely, as the community expects.
‘Community confidence exists when the public can see that Australia’s largest businesses are contributing to the tax system in the knowledge that the ATO closely monitors compliance and takes action against those that don’t pay the right amount of tax,’ Ms Sams said.
Corporate tax transparency report data
The ATO is required by law to publish tax information reported by certain large corporates each year. The 2024–25 CTT report covers 4,299 corporate entities, of which:
- 1,824 are foreign-owned companies with an income of $100 million or more
- 593 are Australian public entities with an income of $100 million or more
- 1,882 are Australian-owned resident private companies with an income of $100 million or more.
Together, these entities paid $87.5 billion in corporate income tax in 2024–25.
The CTT report continues to include data on Australian-owned private entities with total income between $100 million and $200 million.
The information in the report is sourced directly from tax returns and does not reflect any intervention or compliance activities undertaken by the ATO after lodgment.
Oil and gas
Corporate tax paid by the oil and gas segment for the year was $10.6 billion, the sector’s second highest contribution since CTT reporting began.
The number of entities paying petroleum resource rent tax (PRRT) has reached a record of 21 following the introduction of the deductions cap on 1 July 2023 which limits the amount of deductible expenditure available to offset assessable receipts for liquefied natural gas (LNG) projects.
Despite lower commodity prices, PRRT payable increased by more than 26%, rising from $1.48 billion in 2023–24 to $1.87 billion in 2024–25, marking the second highest amount since reporting commenced.
‘The number of PRRT payers has almost doubled since 2023, as more LNG projects become subject to the deductions cap,’ Ms Sams said.
Tax Avoidance Taskforce
The Australian Government continues to invest in the ATO’s Tax Avoidance Taskforce, strengthening the ATO’s ability to scrutinise large public and private groups, multinational enterprises and high-wealth individuals.
The Taskforce helps ensure these taxpayers are paying the right amount of tax by providing assurance, addressing tax avoidance risks and challenging aggressive tax arrangements that threaten Australia’s revenue base.
Australia has high levels of tax compliance of large business with 94.3% of tax paid voluntarily, and 96.3% after ATO compliance actions.
Since its establishment in 2016, the Taskforce has secured more than $36 billion in additional tax revenue from multinational enterprises, and large public and private businesses (as at 30 June 2026).
‘The Tax Avoidance Taskforce continues to deliver strong returns for the community by ensuring large businesses and wealthy groups pay the right amount of tax,’ Ms Sams said.
2026 public and multinational businesses findings reports
Last month, the ATO also published its findings reports, giving the community greater insight into large market risks, the ATO’s assurance programs and its engagement with large public and multinational businesses.
This year, some reports include new information to connect ATO programs to the Public and Multinational Business (PMB) three-tier model (3TM) which reflects the different ways taxpayers interact with the tax and super systems.
The reports continue to demonstrate the majority of taxpayers in both the Top 100 and Top 1000 assurance programs achieve either overall high or medium assurance ratings. The level of low-risk disclosures across key risks such as marketing hubs, related party finance, hybrid mismatch and inbound distributions continues to increase, while high-risk disclosures remain low.
‘These reports provide transparency to the community around large market compliance,’ Ms Sams said.
