The Australian Taxation Office (ATO) continues to intensify its compliance activities on privately owned groups, driven by its focus on reducing the tax gap within this market and in building "justified trust".
The tax gap is the difference between what the ATO theoretically expects the tax revenue to be, compared to the actual revenue collected. The current tax gap within high net worth individuals and private groups is higher than the tax gap for multinational corporations and large Australian corporations - therefore, the Government continues to provide funding to the ATO in targeting this community of taxpayers.
Backed by strong funding and demonstrated return on investment, the ATO is also now better equipped to identify and address potential compliance issues through increased access to data and data matching capabilities.
The ATO has a number of risk-based programs specifically focussed on private groups.
The two key risk review programs are the Top 500 and Next 5,000.
In brief, the Top 500 program targets Australia’s largest private companies, with reference to factors such as turnover, net assets and market leaders or groups of specific interest. There have been some changes to the taxpayers who fall within the Top 500 program, effective from April 2025.
The Next 5,000 program focuses on reviewing Australian resident individuals, who together with their associates, control wealth of more than $50 million. Within this program, there are 3 types of engagements:
Risk-based programs scrutinise significant transactions - notably those exceeding $20 million, or those of public interest.
There are three main categories of risk areas the ATO focuses on - foundational issues, emerging or evolving risks and targeted focus areas. This forms a comprehensive framework for understanding the ATO’s focus areas.
These are based on the risks and issues identified through data collection, analysis and case work.
It is essential for private groups to understand the ATO’s targeted areas of concern. Doing so is critical to maintain compliance, minimise tax risks and prepare for increased attention from the ATO.
With advancements in technology, the ATO has access to more data than ever before. Real-time data analysis allows the ATO to quickly identify patterns of non-compliance through inconsistent information disclosed on different sources of filings and/or publicly available information.
Private groups and high net wealth individuals should ensure the accuracy and timeliness of their tax obligations. Issues to consider include:
In parallel with foundational issues, the ATO is proactively identifying emerging risks that reflect the current business environment. These include:
The ATO has also identified sectors and market thematics that are of specific interest.
1. Succession planning: With Australia’s ageing population, succession planning may involve preparing your business for sale, or planning to transfer control or wealth to family members. With this, there are complex tax issues to consider, including:
2. Private equity: risks across the life cycle of private equity investment, including tax outcomes for all private equity participants (funds, private businesses and investors) at different stages of the private equity lifecycle (pre-acquisition, acquisition, holding, pre-exit and exit).
3. GST focus areas: the ATO are focussed on two key industries, being retail and construction.
With the ATO strengthening its focus on tax compliance in privately owned groups and high net wealth individuals, staying informed and prepared is critical to mitigate risks. Understanding these key focus areas will enable private groups to remain compliant and prepared throughout 2025 and beyond.
