Treasury Laws Amendment (Strengthening Accountability for Tax Adviser Misconduct and Other Measures) Bill 2026

High-Level Summary
This bill introduces a suite of reforms to strengthen tax practitioner regulation, broaden the foreign resident capital gains tax (CGT) base, and refine merger control laws. It also includes measures to support renewable energy investment and philanthropy. The reforms are largely a response to the PwC tax leaks matter and aim to align Australian tax and competition laws with international standards while providing greater clarity and proportionality in enforcement.

Summary

The Bill implements a multi-faceted reform package targeting tax integrity, competition, and philanthropy. A primary focus is strengthening the Tax Practitioners Board (TPB) in response to the PwC tax leaks matter. As noted in the memo, the reforms "implement a stronger penalties framework that will more effectively penalise and deter inappropriate conduct by both registered tax practitioners and unregistered preparers" [EM page 9]. This includes new criminal offences and significantly higher civil penalties.

The Bill also broadens the foreign resident Capital Gains Tax (CGT) regime to ensure Australia "receives its fair share of tax on gains made from assets with a close connection to Australia’s land and natural resources" [EM page 10]. This involves a new statutory definition of "real property" and an integrity-focused 365-day Principal Asset Test. To balance this, a transitional 50% CGT discount is provided for renewable energy assets to support the energy transition.

In competition law, the Bill refines the merger control regime by replacing the "automatic voiding of acquisitions that are required to be notified but are not... with a court-supervised voidable model" [EM page 12]. This aims to prevent unintended consequences while maintaining strong anti-competitive protections. Other measures include renaming ancillary funds to "Giving Funds" and listing new Deductible Gift Recipients to encourage philanthropy.


Argument For
Normative Bases
  1. Utilitarian Ground Truth
  2. Legal Principle
  3. Pro-Democracy

The case for this Bill rests on the necessity of restoring public confidence in the integrity of the Australian tax system and ensuring a level playing field for all participants. The enhancements to the Tax Practitioners Board's regulatory powers are a direct and proportionate response to systemic failures exposed by the PwC tax leaks scandal. By introducing criminal penalties for unregistered preparers and increasing civil penalties for misconduct, the Bill creates a robust deterrent against unethical behaviour that undermines the revenue base and public trust [Judgment].

Furthermore, the strengthening of the foreign resident CGT regime aligns Australian law with international OECD standards. It addresses a significant "gap... between the intended and actual operation of the regime" where state and territory laws were used to narrow the tax base [EM page 45]. Ensuring that foreign residents pay their fair share of tax on assets deriving value from Australian land is a matter of fundamental fiscal fairness. The transitional discount for renewable energy assets demonstrates a pragmatic approach, balancing revenue integrity with the urgent need to attract foreign investment for the climate transition [Judgment].

Finally, the refinements to the merger control regime improve the proportionality of the law. Moving from automatic voiding to a court-supervised model prevents disproportionate commercial damage from inadvertent non-compliance while preserving the ACCC's ability to intervene in anti-competitive acquisitions.


Argument Against
Normative Bases
  1. Individual Autonomy
  2. Value-Neutral / Epistemic Objection

The primary objection to this Bill concerns the expansion of state power and the imposition of strict liability in the regulatory regime. Schedule 1 introduces criminal offences where "strict liability applies to the physical elements... and the circumstance of the practitioner not being registered" [EM page 25]. This removes the requirement for the prosecution to prove a mental fault element (mens rea), which is a significant departure from traditional legal principles protecting individual liberty [Judgment]. Such measures risk penalising individuals for honest mistakes in a complex regulatory environment.

Additionally, the broadening of the foreign resident CGT regime may create significant uncertainty and compliance burdens for international investors. By moving away from the ordinary meaning of "real property" to a broader statutory definition that includes various "closely related interests," the Bill increases the complexity of the tax code. This epistemic complexity may deter foreign capital, as investors struggle to determine their liabilities under a regime that is "unencumbered by state or territory laws" [EM page 48] that they may already be familiar with.

There is also a concern regarding the "interim suspension" powers granted to the TPB, where the "natural justice hearing rule does not apply" [EM page 38]. While intended for egregious cases, the ability of a regulator to immediately halt a professional's livelihood without a prior hearing or formal investigation represents a significant risk of administrative overreach and a lack of procedural fairness [Judgment].
