The question that most structures fail to answer
When a foreign entrepreneur incorporates a Singapore company, they have answered one question: where is the company registered? They have not answered the question that matters far more for their tax position: where are they, and where is their company, actually tax resident?
Tax residency is the concept that determines which jurisdiction has the right to tax your income and on what basis. It is not determined by where you incorporate. It is not determined by where you open a bank account. And for most Greater China entrepreneurs in the process of relocating to Singapore, it is not automatically resolved by the act of physical relocation. Tax residency is a legal determination, made independently by each jurisdiction, based on a set of factual tests that most clients have never been clearly explained.
Getting it wrong — or assuming it has resolved itself — is one of the most consequential planning failures we see.
Two separate questions: corporate and individual
Tax residency operates at two distinct levels, and both matter.
At the corporate level, a company’s tax residency determines which country has the right to tax its profits on a worldwide basis. Singapore determines corporate tax residency based on where central management and control is exercised, the place where the key management and commercial decisions for the conduct of the business are in substance made. As the IRAS e-Tax Guide on Double Taxation Agreements confirms, this is a substance test, not a registration test. A Singapore-incorporated company managed from China may be tax resident in China. A China-incorporated company genuinely managed from Singapore may, in principle, be tax resident in Singapore with consequences that cut in both directions.
At the individual level, a person’s tax residency determines which country has
the right to tax their personal income — salary, dividends, director’s fees, investment returns, and in many jurisdictions, capital gains. Individual and corporate tax residency are entirely separate questions. A client may have cleanly established their Singapore company’s tax residency while remaining personally tax resident in China, Australia, or another home jurisdiction — and subject to that jurisdiction’s personal income tax on worldwide income.
Both questions must be asked and answered. One does not resolve the other.
How Singapore determines individual tax residency
Singapore determines individual tax residency under the Income Tax Act. A foreigner is treated as a Singapore tax resident for a year of assessment if they have been physically present in Singapore for at least 183 days in the calendar year, or if they have been employed in Singapore for a continuous period spanning two calendar years amounting to at least 183 days in total.
Singapore citizens and Permanent Residents who are ordinarily resident in Singapore are also treated as tax residents.
Singapore’s individual tax treatment is attractive for residents: Singapore- sourced income is taxable at progressive rates, Singapore does not impose capital gains tax, and foreign-sourced income received in Singapore by individuals is generally exempt from tax.
But the Singapore side is only half of the picture. The critical question, which most advisors do not raise is what the client’s home jurisdiction is doing simultaneously.
How China determines individual tax residency — and why physical relocation is not enough
China’s Individual Income Tax (“IIT”) Law establishes two independent bases for PRC tax residency. A person is a PRC tax resident if they satisfy either of the following.
The first basis is domicile. A person is treated as having a domicile in China if they habitually reside in China by reason of any one of three factors:
- Household registration in China;
- Family ties (spouse or dependents ordinarily residing in China); or
- Economic interests, including controlling PRC businesses, holding primary assets in China, or having principal economic activity in China
These three factors are independent — satisfying any one of them is sufficient to establish domicile and therefore PRC tax residency.
The second basis is the 183-day physical presence test. A person with no PRC domicile who is physically present in China for 183 or more cumulative days in a tax year is treated as a PRC tax resident for that year.
The critical point — and the one that most clients do not fully appreciate — is that the domicile test takes priority. The 183-day test only applies where the client has no PRC domicile. If domicile is established under any of the three factors, the client is a PRC tax resident regardless of how many days they spend in China.
A client who has relocated to Singapore but retains their household registration, whose spouse remains in China, or who continues to control a PRC operating company as their primary economic interest, remains a PRC tax resident.
Physical relocation to Singapore does not break that.
A PRC tax resident is subject to Chinese IIT on worldwide income — including Singapore salary, Singapore dividends, and capital gains on assets held globally.
How Australia determines individual tax residency — a different but equally demanding standard
Australia’s tax residency rules operate on a different framework but produce equally demanding obligations for those who fail to cleanly exit.
The primary test is the resides test: if a person resides in Australia, they are an Australian resident for tax purposes without the need to apply any further test. Residency under this test is assessed by reference to physical presence, intention and purpose, family ties, employment connections, maintenance and location of assets, and social and living arrangements. An Australian entrepreneur who has moved to Singapore to build a business but maintains their family home in Australia, whose children remain enrolled in Australian schools, and who returns frequently, may well still reside in Australia for tax purposes — regardless of the number of days they physically spend in Singapore.
If the resides test is not satisfied, three statutory tests may still establish Australian tax residency — including the domicile test, under which a person is treated as Australian resident if their domicile is in Australia unless their permanent place of abode has been established elsewhere. As the ATO has made clear, a legal decision confirms that a person who fails to cut their connection with Australia will be treated as an Australian resident. The CGT implications of ceasing Australian residency are also significant: upon becoming a foreign resident, certain assets are deemed disposed of for CGT purposes, and the main residence exemption for Australian property may be unavailable for foreign residents who sell after certain dates.
The dual residency problem — and the DTA tie-breaker
A client who establishes Singapore tax residency without cleanly breaking their home jurisdiction’s tax residency becomes simultaneously resident in both jurisdictions. This is the most common and consequential planning failure in cross-border relocation.
Where dual residency arises under both countries’ domestic laws, the applicable Double Taxation Agreement provides a sequential tie-breaker to determine which country has the primary right to treat the individual as a tax resident for treaty purposes. The China-Singapore DTA Article 4(2) tie-breaker applies, in order:
- Permanent home available;
- Centre of vital interests;
- Habitual abode; and
- Nationality.
This sequence matters. A PRC national in the early stages of Singapore relocation, who has not yet cancelled their household registration, whose family is partially remaining in China, and whose primary business remains PRC- based, will frequently not produce a clean Singapore-resident outcome at the permanent home or centre of vital interests steps. If Steps 1 and 2 cannot be resolved in Singapore’s favour, the tie-breaker proceeds to nationality — which for a PRC national who has not acquired Singapore citizenship, resolves in China’s favour. That means the client is treated as a PRC tax resident for DTA purposes, regardless of how many days they spend in Singapore and regardless of whether they have incorporated a Singapore company.
The Australia-Singapore DTA operates on similar tie-breaker principles — permanent home, then centre of vital interests, then habitual abode, then nationality.
Breaking home jurisdiction residency: the steps most clients skip
Establishing Singapore residency is necessary. Breaking home jurisdiction residency is equally necessary — and the two processes must be managed in parallel, not sequentially.
For PRC clients, breaking tax residency on domicile grounds requires eliminating all three domicile factors simultaneously. A client who cancels their household registration but retains a spouse in China and continues to control a PRC operating company as their primary income source has eliminated only one of the three factors. They remain a PRC tax resident.
The formal mechanism for exiting PRC tax residency through household registration cancellation is the emigration tax clearance process, which requires settlement of all outstanding PRC IIT — including IIT on overseas income that should have been declared in prior years — before the cancellation can be processed. This is a statutory requirement under the PRC IIT Law and cannot be circumvented. For clients with historical non-compliance, the clearance process will expose it. Early and proactive engagement with qualified PRC tax counsel is essential.
For Australian clients, ceasing tax residency requires establishing a clear permanent place of abode outside Australia, with supporting evidence — lease agreements, family relocation, termination of Australian economic ties — sufficient to demonstrate to the ATO that the connection with Australia has been genuinely broken.
Why tax residency must be addressed before the structure is designed
The tax residency question is not a matter to be addressed after incorporation. It is the foundational input to any cross-border structuring decision. The company’s registered jurisdiction, its governance arrangements, the location of its directors, the flow of dividends to the shareholder, the shareholder’s personal tax position, and the CRS reporting obligations that flow from all of the above — all of these are shaped by where the client and the company are actually tax resident.
At BBCG, our approach begins with a structured diagnostic that maps the client’s current tax residency position across both jurisdictions — identifying where residency currently sits, what it would take to establish Singapore residency, what it would take to exit home jurisdiction residency, and what the exposure is during the transition period. We frame the issues, sequence the actions, and coordinate with qualified tax counsel in both jurisdictions. We do not render tax opinions. What we ensure is that the right questions are asked — and that no structure is recommended until those questions have been answered.
Practical next step
If you are relocating from Greater China or Australia to Singapore, or if you have already incorporated a Singapore structure without a formal residency assessment, the right starting point is a diagnostic conversation, not an incorporation form.
Tax residency determines everything that follows. Getting it right from the outset is substantially less costly than correcting it when a tax authority in another jurisdiction eventually asks.
Compliance caveats
This article provides a general educational overview of individual and corporate tax residency concepts across Singapore, China, and Australia. It draws on publicly available guidance including the IRAS e-Tax Guide on Avoidance of
Double Taxation Agreements (Fourth Edition, 30 January 2026), Australian Taxation Office published residency guidance (updated to August 2025), the PRC Individual Income Tax Law and its Implementing Regulations, and the China–Singapore Double Taxation Agreement. It does not constitute tax advice, legal advice, or a professional assessment of any individual’s tax residency status. Tax residency determinations are highly fact-specific and jurisdiction- specific. The rules of each jurisdiction, particularly China’s, are complex and evolving. Formal advice from qualified tax counsel in all relevant jurisdictions is required before making any decisions about residency, structuring, asset disposal, or emigration. PRC emigration tax clearance in particular requires formal engagement with qualified PRC tax counsel and cannot be managed without specialist input. IRAS guidance and PRC tax law should be verified against current published positions.
