Review: ATO’s management of remission of the general interest charge

The government and community should be compensated for deliberate late payment of tax liabilities and that late payment should not be rewarded, but there may be a range of factors that hamper a taxpayer’s ability to pay their liabilities on time. This review will explore whether ATO GIC decisions are supported by policies, systems and processes that align with principles of good tax administration, such as consistency, transparency and getting it right.

Review: Systemic review of the effectiveness of the ATO’s registered agent phone line

STATUS: Review completed October 2025

We conducted a review into the ATO’s registered agent phone line in response to increasing complaints of poor service. 

Registered tax agents play a vital role in the Australian tax system, representing 62% of individual taxpayers and 96% of other taxpayers.

The ATO encourages registered agents to use its online services but, with 65% of agents reporting problems, there is still a strong demand for their dedicated registered agent phone line. 

Our review looked into the differences between what registered agents expect of the phone service and what the ATO provides, as well as how the ATO is consulting with agents, to make recommendations on how the service can be improved.

We undertook widespread consultation with the tax community in early 2025 to inform our review and final recommendations. We thank all those who participated in the review through submissions, an online survey and consultation activities. 

Reviews of allegations of maladministration involving bias and prejudice

A review into the ATO’s management of a complex and long-running case

19 May 2026

We have completed our independent investigation into the ATO’s management of a complex and long-running case, which stretches back over ten years. 

Our review examined allegations of maladministration raised by a taxpayer and reported in the media in mid-2025.   

The role of the Tax Ombudsman is to improve the fairness and integrity of the tax system and we take very seriously any allegations where maladministration is alleged.  

Our investigation found that some but not all allegations of maladministration against the ATO were substantiated. 

I have reported my findings to the Commissioner of Taxation in relation to the historical procedural failings within the ATO, which did not meet the community’s expectations of an objective and impartial tax administrator.  

Equally, within our investigation we found there was no evidence to substantiate some of the complainant’s more serious allegations 

We will not be commenting further on the specifics of our findings. They are now a matter for the taxpayer and the ATO to consider. 

We will not be releasing the report publicly as it contains personal data about the taxpayer. We are legally required to maintain the confidentiality of all complaints.  

A review into the ATO’s controls for bias in decision-making and disclosures 

27 July 2026 

Based on our review into the ATO’s management of a complex and long-running case, this follow-up review considered broader systemic risks of bias or prejudice in the ATO’s decision-making and inappropriate disclosures of taxpayer information. It examined whether the failings identified in the historic case could occur now and whether the ATO’s current controls were effective in mitigating such risks. 

We found that the ATO has strengthened its controls to improve decision-making in recent years, in response to weaknesses identified 10 to 15 years ago, but there is room for improvement.  

Bias and prejudicial conduct can impact tax administration in many ways. For example, officers may depart from procedures or the law to reach a predetermined outcome because they believe they are acting in a “noble cause”. Alternatively, investigators can give too much weight to past compliance behaviours instead of looking at current evidence with fresh eyes.

Given the nature of the topic that was reviewed and our specific focus on the ATO’s internal controls, we did not seek broad public input for this review. However, we undertook targeted consultation with selected tax professionals and associations to gather insights into their experience with the tax system.

Our review is now complete and the full report is available below.

Review: Letters from the ATO

The ATO sends more than 140 million letters and messages to Australians each year and invests considerable taxpayer funded resources into developing and distributing them. 

But many people still say they find some letters confusing, too technical, and their tone can cause unnecessary stress and anxiety. 

We conducted this review because the ATO has a responsibility to engage with taxpayers in ways that make it easy to understand their obligations and any actions they need to take. 

The review looked at the ATO’s process for designing and testing high volume letters and examined a sample of some of the most complex letters.

Review: Identification and management of financial abuse within the tax system

Financial abuse can happen to anyone. Data from the Australian Bureau of Statistics shows that 1 in 6 women (16% or 1.6 million women) and 1 in 13 men (7.8% or 745,000 men) have experienced economic abuse by an intimate partner. Financial abuse can occur through many different types of practices, including weaponisation of the tax system. The impacts on victim-survivors (and their families) can be devastating and long lasting, with substantial financial burdens and ongoing instability and stress caused by debts they did not personally incur.

We conducted this review because more needs to be done to understand how the tax system is being weaponised and what action is required from the Australian Taxation Office (ATO) to address it and provide appropriate support and remediation for those affected.

Review: ATO online services for agents

Status: Review completed, August 2026

Online Services for Agents (OSfA) is a secure system provided by the ATO for registered tax and BAS agents. It allows agents to access a range of client information and services, offering real-time visibility and control over client data. 

The ATO has been encouraging agents to use self-service platforms like OSfA to streamline processes and reduce reliance on phone support. And we know agents far prefer to transact online than to call the ATO. Using online channels makes interactions more efficient and reduces wait times for agents. We understand that time is money for agents!  

However, feedback from recent consultation with the agent community as part of our Review of the Registered Agent Phone Line highlighted several issues and concerns with OSfA and its integrated communication channel: Practice Mail.  

Agents reported inefficiencies in using the portal .They also said they would be more likely to use OSfA if it had the capability to fulfil their key transaction requirements and could do so in a timely way to meet the needs of their clients. These issues have raised questions about the system’s effectiveness and usability, which is why we commenced this review in early 2026.    

The review examined what specific changes are required for OSfA and Practice Mail to deliver the functionality and responsiveness that agents need to perform their roles efficiently and with confidence. Consultation was undertaken with the tax community in March and April 2026 to seek feedback and suggestions for improvement. 

The review found ATO Online Services for Agents is not keeping pace with tax agents’ needs, with agent satisfaction falling from 76% in 2022 to 63% in 2026. 

We made 3 recommendations to the ATO to help modernise its digital services, cut admin burden and make it easier for agents to support their clients. These improvements will create efficiencies for agents and the clients they serve and promote greater and more timely voluntary compliance with tax and superannuation obligations.   They will also deliver efficiencies for the ATO, its systems and staff.  

The ATO accepted all three recommendations and we will monitor its progress on implementation. 

Review: ATO administration and management of Objections

The report on objections finalises a review that has been conducted over several years, including the publication of an interim report on 10 October 2022.

Objections are an essential part of the tax system and are often the only affordable option open to many taxpayers to challenge tax office decisions. We believe it’s imperative that the function is easily accessed and operates without undue delays.

Our report has recommended changes to make it faster and simpler for all taxpayers to lodge an objection with the ATO. The report highlights 4 areas of improvement:

  • increasing accessibility by extending online lodgement to all taxpayers
  • streamlining processes to reduce time and resources devoted to high volume, low risk objections
  • increasing taxpayer engagement to speed up the time taken to complete an objection
  • learning lessons from objections to prevent the number of objections needing to be made.

Review: Tax identity fraud – an own-initiative investigation

This is the interim report of our own initiative investigation into tax identity fraud, focusing on the importance of bank account integrity. The report focuses on the ATO’s risk management controls to prevent fraudsters from changing the bank account details on legitimate taxpayers’ ATO accounts, which is a fundamental step in obtaining fraudulent refunds from the tax system.

This is the interim report of our own initiative investigation into tax identity fraud, focusing on the importance of bank account integrity. The report focuses on the ATO’s risk management controls to prevent fraudsters from changing the bank account details on legitimate taxpayers’ ATO accounts, which is a fundamental step in obtaining fraudulent refunds from the tax system.

Following the commencement of our investigation, the Tax Ombudsman received numerous submissions from the taxpayer and tax practitioner community that raised concerns about the ATO’s lack of action in detecting and preventing tax identity fraud. We also investigated ATO actions taken in response to potential tax identity fraud that were the subject of taxpayer disputes (unresolved complaints).

We make 13 recommendations for ATO improvement in this interim (Phase 1) report.

Review: The exercise of the Commissioner’s general powers of administration

This report examines the nature and purpose of the Commissioner’s General Powers of Administration (GPA). Through five case studies, the report examines how the GPA is exercised. Although many unremarkable decisions are made each day under the GPA, significant decisions such as settlement of tax disputes and implementation of relief measures during the COVID-19 pandemic also rely upon the GPA.
