Australian Tax for Australians and Founders Living in Singapore

Direct answer: a Singapore visa, apartment or company does not by itself end Australian tax residence or move an Australian business. The same analysis is required where the client is already living in Singapore and now wants a second opinion. Personal residence, CGT event I1, company control, permanent establishments, staff, contracts, intellectual property, funding and intercompany pricing must be aligned to the actual operating model.
What changes for an Australian already living in Singapore
Australia applies its own individual-residence tests. No single day count, employment pass or Singapore tax return determines the Australian position.
Singapore generally treats a foreign individual as resident when the relevant presence or work conditions are met, including the 183-day rule and specified administrative concessions.
If Australian residence ceased, CGT event I1 may affect founder shares, private-company interests, options and other assets. If it did not cease when assumed, earlier foreign-income and return positions may require review.
A Singapore company is tax resident where its control and management is exercised, not merely because it was incorporated there.
An Australian company may remain Australian resident while also creating Singapore taxable presence through the founder, staff, contracts or a fixed place of business.
Related-party services, software development, licences, funding and distribution arrangements should reflect the real functions, assets, risks and decision-making in each country.
Founder and company decision matrix
1. When did Australian residence cease, if at all?
The review should reconstruct the founder’s Singapore home, family location, expected duration, Australian home and assets, business authority, return pattern and actual conduct from the date of departure. Physical presence in Singapore is significant evidence, but a founder can be Singapore resident while remaining Australian resident under domestic law.
2. Is treaty residence relevant?
Where both countries treat the person as resident, the Australia–Singapore treaty may allocate treaty residence using the applicable tie-breaker provisions. That process does not automatically erase every domestic-law consequence, and each category of income, asset and entity must still be analysed.
3. Where are the companies controlled and carrying on business?
Singapore considers where company control and management is exercised. Australia considers incorporation and, for foreign-incorporated companies, whether business is carried on in Australia with central management and control or resident-shareholder voting control. Board papers, banking authority, budgets, senior hiring, product decisions and major contracts should match what occurs in practice.
4. Does earlier advice need correction?
A client already in Singapore may have received compliance advice without a complete residence, CGT, company-control or transfer-pricing analysis. Extax can reconstruct the timeline, test prior conclusions and identify whether returns, elections, agreements or governance need correction.
Worked scenario: the founder has already moved
An Australian founder has lived in Singapore for eighteen months and incorporated a Singapore sales company. The Australian company still owns the software, employs the engineering team and signs established customers. The founder approves product strategy, budgets and senior hires from Singapore and negotiates major Asian contracts. The prior accountant has treated the matter principally as two annual tax returns.
The review must determine Australian and Singapore residence from the actual dates, consider treaty residence and CGT event I1, test the Australian company’s residence and Singapore permanent-establishment exposure, and define the Singapore company’s genuine role. Sales, management, development and licence charges need to reflect the actual functions and control exercised in each country.

Frequently asked questions
Can Extax review my position after I have already moved to Singapore?
Yes. The work can reconstruct the residence and transaction timeline, test prior advice, review Australian positions and identify the treatment, corrections and evidence required going forward.
Does spending 183 days in Singapore end Australian residence?
No. The Singapore day-count rules and Australian residence tests are separate. The Australian outcome depends on the person’s full pattern of life and connections, with the treaty considered where both countries treat the person as resident.
Does incorporating in Singapore move the Australian business?
No. Incorporation creates a legal entity. It does not by itself move strategic control, employees, IP, customer relationships, risks or the Australian company’s tax residence.
Review an existing or proposed Singapore position
Extax can review a proposed move or an arrangement already operating from Singapore, including Australian residence, CGT event I1, treaty residence, company control, permanent establishments, IP, transfer pricing, employment, funding and correction issues.
