Why tax residency matters more than ever for globally mobile families and businesses
In today’s world, it is increasingly common for individuals and businesses to operate across multiple countries. Entrepreneurs relocate for opportunities, families move for lifestyle, and companies transact globally with ease.
However, while mobility has increased, tax systems remain firmly tied to jurisdiction and residency. Where you are considered a tax resident can dramatically influence:
- The tax you pay
- The assets subject to taxation
- Your reporting obligations
- Your estate and succession planning
At New Leaf Advisory, we regularly assist clients navigating the complexities of international tax residency. This often arises when circumstances or events have the potential to impact their current or future tax residency. Whether an individual is relocating overseas or a business is transacting globally, understanding how tax residency works from a global perspective is essential.
What Is Tax Residency?
Tax residency determines which country has the right to tax your income, capital gains, and sometimes your global assets.
In simple terms:
- Tax residents are generally taxed on their worldwide income.
- Non-residents are typically taxed only on income sourced within that country.
Each country has its own residency tests, and these tests often consider factors such as:
- Physical presence
- Permanent home
- Family location
- Business or employment ties
- Long-term intentions
This means someone may be considered a resident in more than one country at the same time, which is where international tax planning becomes critcal.
Why Tax Residency Is Increasingly Complex
Historically, determining tax residency was relatively straightforward. Today, global mobility and digital work environments have made the analysis far more nuanced.
Common scenarios we see include:
- Business owners relocating overseas while retaining Australian investments
- Families with members living in different jurisdictions
- Entrepreneurs operating companies across multiple countries
- Investors holding assets in several tax jurisdictions
- Individuals spending significant time in Australia but living abroad
In these situations, tax residency is rarely a simple “yes or no” answer. It requires careful analysis and planning.
The Risks of Getting Tax Residency Wrong
Misunderstanding your tax residency can lead to significant consequences.
These may include:
- Unexpected tax liabilities
- Double taxation across jurisdictions
- Capital gains tax triggered on departure
- Penalties for non-compliance
- Complex reporting obligations
Without proactive planning, individuals may inadvertently trigger tax outcomes they never anticipated.
For this reason, tax residency decisions should always be approached strategically rather than reactively.
Case Study: International Tax Residency Planning – Migration to Singapore
One of our recent engagements involved advising a client relocating their tax residency from Australia to Singapore. With a significant asset base of approximately $50 million and family members potentially residing across multiple jurisdictions, the move required far more than simply changing addresses.
At New Leaf Advisory, we specialise in cross-border tax planning and worked closely with the client’s legal, financial, and estate planning advisers to provide a comprehensive strategy. Our role included:
- Modelling current and future capital gains tax exposures to minimise unintended liabilities
- Assessing the interaction between Australian tax residency rules and Singapore residency
- Reviewing director and officeholder roles across family entities
- Aligning tax planning with succession and estate planning objectives
- Designing family governance structures to support long-term wealth and decision-making
A critical component of our engagement was long-term modelling, not just immediate tax outcomes. We analysed how future events—such as asset sales, generational transfers, and potential relocation of family members—could impact tax exposures.
By approaching the transition strategically and leveraging insights from the client’s broader professional team, the client was able to relocate with clarity and confidence, ensuring their global structure supported both financial and family objectives.
This case highlights how proactive international tax residency planning can significantly reduce risk, protect wealth, and simplify complex cross-border transitions for high-net-worth individuals and families.
The Capital Gains Tax Exit Issue
One of the most significant issues when leaving Australia is the potential capital gains tax (CGT) event triggered when tax residency changes.
When an individual ceases to be an Australian tax resident, certain assets may be treated as if they were disposed of at market value at the time of departure.
This can create a substantial deemed capital gain, even if the asset has not actually been sold.
Planning opportunities exist, including:
- Deferring the CGT event in some cases
- Re-structuring asset ownership prior to departure
- Reviewing which assets remain taxable Australian property
- Modelling the timing of disposals
Without careful planning, individuals relocating overseas can inadvertently trigger large and unexpected tax liabilities.
Cross-Border Business Transactions
Tax residency issues are not limited to individuals. Businesses operating across borders must also manage complex tax reporting obligations.
One example is the International Dealing Schedule (IDS), which forms part of Australia’s transfer pricing and international tax reporting framework.
The IDS requires businesses to disclose detailed information about cross-border related-party transactions, including:
- Intercompany loans
- Management fees
- Service arrangements
- Asset transfers
- Financial flows between related entities
These disclosures are closely scrutinised by the Australian Taxation Office and require accurate and well-supported data.
Case Study: International Dealing Schedule for a Global Freight Business
We recently worked with the corporate accountant of a large freight forwarding business that operates across multiple tax jurisdictions.
The group had substantial international activity, including cross-border transactions between related entities. Preparing the International Dealing Schedule required:
- Collecting transaction data from multiple countries
- Reconciling foreign balances and currencies
- Aligning accounting records across jurisdictions
- Reviewing the nature of related-party transactions
- Preparing and supporting a detailed IDS disclosure
Our role was to work collaboratively with the internal accounting team to ensure the data was accurately reconciled and the disclosure met the required reporting standards.
The process required significant coordination and technical expertise, particularly given the scale and complexity of the group’s international dealings.
The Growing Importance of International Tax Advice
Global mobility will only continue to increase.
We are seeing a rising number of clients:
- Relocating overseas for business or lifestyle
- Holding investments across multiple jurisdictions
- Running international businesses
- Structuring family wealth across borders
Each of these situations introduces tax residency considerations that require careful planning.
The key is to approach international tax with a long-term perspective. Decisions made today can influence tax outcomes many years into the future.

Final Thoughts
Tax residency is one of the most important—and often misunderstood—areas of international tax.
Whether relocating overseas, operating a global business, or managing family wealth across borders, understanding how tax residency works is essential.
The difference between proactive planning and reactive decision-making can often be measured in millions of dollars in tax outcomes.
If your personal or business circumstances involve multiple jurisdictions, it is worth seeking advice early. With the right structure and planning, international mobility can be an opportunity rather than a tax risk.
