Government Removes Retrospective Foreign Tax Changes Following CPA Australia Campaign

The Federal Government has abandoned controversial retrospective changes to Australia’s foreign resident capital gains tax (CGT) rules after sustained advocacy from CPA Australia, providing greater certainty for investors, taxpayers and tax professionals.

The changes, contained in legislation introduced to Federal Parliament, remove a key provision that would have retrospectively applied expanded foreign resident CGT rules to transactions dating back almost 20 years.

Instead, the new laws will apply only to future transactions, while also introducing legislative protections that prevent historical tax assessments from being reopened outside the normal amendment periods.

CPA Australia has welcomed the decision, describing it as a significant victory for fairness, certainty and Australia’s reputation as a stable destination for international investment.

Retrospective Tax Proposal Abandoned

The original exposure draft released earlier this year proposed expanding Australia’s foreign resident capital gains tax rules and applying them retrospectively to transactions dating back to 12 December 2006.

The proposal attracted widespread concern from tax professionals and investors, who argued it would fundamentally change the tax treatment of transactions completed many years ago, creating uncertainty for taxpayers who had acted in accordance with the law at the time.

CPA Australia lodged a detailed submission to Treasury in April, warning that retrospective taxation would undermine confidence in Australia’s taxation system and create significant legal uncertainty.

The organisation argued that changes of this magnitude should only apply prospectively rather than rewriting tax obligations on historical transactions.

Certainty Restored for Taxpayers

CPA Australia Tax Lead Jenny Wong said the Government had listened to industry concerns and adopted a more balanced approach.

She said removing the retrospective provisions was an important outcome because the original proposal would have effectively rewritten tax rules stretching back nearly two decades.

Ms Wong said applying the reforms only to future transactions delivers the certainty taxpayers and investors require when making long-term financial decisions.

She also welcomed the inclusion of legislative protections preventing the Australian Taxation Office from reopening historical foreign resident CGT assessments outside the standard amendment periods.

The only exceptions will apply where fraud or tax evasion is involved or where reviews, objections or appeals were already underway before 10 April 2026.

Ms Wong said embedding these protections directly into legislation provides far greater certainty than relying on administrative discretion.

Broader Capital Gains Tax Rules Still Expanding

While the retrospective provisions have been removed, the legislation still broadens Australia’s foreign resident capital gains tax regime moving forward.

The Bill introduces a more comprehensive definition of Australian real property, extending the rules to include interests in land, rights over land, structures and assets permanently attached to land, together with certain licences and contractual rights.

It also brings water entitlements and options within the scope of the tax rules, extends the principal asset test from 90 days to 365 days, and confirms that mining, quarrying and prospecting information will be treated as taxable Australian real property.

These measures are designed to provide greater clarity around assets subject to Australian capital gains tax when owned or disposed of by foreign residents.

Consultation Credited for Outcome

CPA Australia said the final legislation demonstrates the value of meaningful consultation between government and industry.

However, the organisation also argued that the original consultation period was far too short for reforms of such significance.

Ms Wong said allowing only two weeks for stakeholders to examine complex tax legislation limited the profession’s ability to identify potential problems before the Bill was drafted.

She encouraged the Government to engage earlier with industry experts on future tax reforms, saying adequate consultation leads to better legislation and greater certainty for taxpayers.

Strengthening Investor Confidence

The decision is expected to be welcomed by foreign investors, multinational businesses and tax advisers who had expressed concerns that retrospective taxation could damage Australia’s reputation as a predictable and stable investment destination.

By ensuring the new rules apply only from the commencement of the legislation, the Government has avoided creating uncertainty around transactions completed under previous laws while still proceeding with broader reforms to Australia’s foreign resident capital gains tax framework.

For tax professionals, the outcome represents an important example of industry consultation influencing legislation before it becomes law, reinforcing the importance of balancing tax integrity with fairness and certainty.
