Singapore has earned its reputation as one of the world’s premier business hubs. Its competitive corporate tax regime, political and economic stability, robust legal framework, and extensive network of Double Tax Agreements (DTAs) continue to attract multinational groups, family offices, and high-growth businesses seeking a regional base.

Yet one of the most frequently misunderstood aspects of Singapore’s tax system is corporate tax residency.

Many business owners assume that once a company is incorporated in Singapore, it automatically becomes a Singapore tax resident. While this may be the approach in some jurisdictions, Singapore adopts a different test.

Tax residency often determines whether a company can access valuable tax concessions and Singapore’s treaty network. For businesses with cross-border operations, getting this right can materially affect the overall tax efficiency of their structure.

Incorporation Is Only The Starting Point

Incorporation establishes a company’s legal existence under Singapore law. Tax residency, however, determines how the company is viewed from an international tax perspective.

Unlike jurisdictions that rely primarily on the place of incorporation, Singapore determines corporate tax residency based on where the control and management of the business are exercised.

This means that a Singapore-incorporated company may still be regarded as a non-resident for tax purposes if strategic decisions are made elsewhere. Conversely, foreign ownership does not prevent a company from becoming a Singapore tax resident.

In a post-COVID world focused on mobility and being a “digital nomad”, it is increasingly common for businesses to establish a Singapore entity while senior executives or directors continue to manage the business from another jurisdiction. 

Without careful governance, the company may inadvertently fail to satisfy Singapore’s tax residency requirements despite being incorporated locally. In many cases, this means the company may instead be treated as tax resident in another jurisdiction, potentially giving rise to additional compliance obligations and tax complexity.

Demonstrating Tax Residency

Singapore’s test for corporate tax residency centers on where strategic control and management are exercised, rather than where day-to-day business activities take place.

In determining a company’s tax residence, the Inland Revenue Authority of Singapore (IRAS) primarily considers where the Board of Directors makes the company’s key commercial and strategic decisions. In practice, this means the physical location that board meetings are held.

For IRAS to treat a company as a tax resident of Singapore, board meetings must be physically held in Singapore. Where the meetings are held outside of Singapore, it is unlikely for IRAS to treat the company as a tax resident of Singapore.  

This above position holds even if the company has an office in Singapore with staff including senior management. The company can operate from Singapore, but without the directors meeting in Singapore to discuss and agree on commercial and strategic matters, the company will not meet the definition of a Singapore tax resident under the Singaporean Income Tax Act. 

Tax Residency Opens The Door To Singapore’s Treaty Network

Perhaps the most commercially significant benefit of Singapore tax residency is access to its extensive network of more than 90 DTAs.

For internationally active businesses, tax treaties do far more than eliminate double taxation. They provide greater certainty over how cross-border income will be taxed and often reduce the overall tax cost of international investments.

Depending on the relevant treaty, businesses may benefit from:

• Reduced withholding tax rates on dividends, interest, and royalties;
• Relief from double taxation through foreign tax credits or exemptions;
• Clearer allocation of taxing rights between jurisdictions;
• Protection from taxation where no permanent establishment exists; and
• Dispute resolution mechanisms where competing tax authorities seek to tax the same income.

These benefits can significantly improve cash flow and reduce the effective tax burden on international transactions.

Certificate Of Residence 

A Certificate of Residence (COR) confirms that IRAS regards the company as a Singapore tax resident for the relevant calendar year. It is commonly requested when companies seek reduced withholding tax rates or other benefits available under Singapore’s DTAs.

In many jurisdictions, the ability to access the concessional tax treatment under a DTA with Singapore is subject to the company presenting a COR from IRAS, covering the financial year in which the treaty provision is claimed.  

Without confirmation from IRAS that the company is a tax resident of Singapore, these benefits under the DTA will be denied. 

Key Takeaway

Singapore’s corporate tax residency rules reinforce a simple but important principle: where a company is managed matters.

For internationally active businesses, Singapore tax residency can unlock significant commercial advantages—from access to domestic tax concessions to the ability to leverage one of the world’s most comprehensive networks of DTAs.

Companies that align their governance framework with Singapore’s tax residency requirements are better positioned not only to access treaty benefits and tax incentives but also to demonstrate the commercial substance and governance standards that increasingly underpin today’s international tax landscape.

U.S. Federal Tax Perspective On Getting The Structure, The Substance, And The Paperwork Right From Day One

Foreign trusts have a reputation problem. Clients tend to arrive with one of two pictures in mind. Either the trust is an impenetrable shield that puts family wealth beyond the reach of every creditor and tax authority, or it is something slightly disreputable that only people with something to hide would consider. Neither picture is accurate, and both get in the way of good planning.

A foreign trust is nothing more exotic than a trust that fails a two-part U.S. classification test. It can be a perfectly ordinary vehicle for a family whose assets, trustees, and heirs sit in more than one country. It can also be the centerpiece of a structure the IRS treats as abusive. What separates the two has almost nothing to do with the trust deed’s jurisdiction. It has everything to do with whether the structure is real, whether control sits where the documents say it sits, and whether every required form is filed on time.

That last point deserves emphasis. In my experience, most foreign trust disasters are not planning failures. They are reporting failures. The plan was defensible, the income tax was paid, and then a form nobody knew about went unfiled for six years. Below is how I work through these structures with clients, and where the expensive mistakes tend to hide.

Start With Classification, Not With The Jurisdiction

Everything downstream depends on a single question, so it belongs at the front of the analysis rather than the end.

For U.S. federal tax purposes, a trust is a U.S. person, commonly called a domestic trust, only if it meets two tests. A court within the United States must be able to exercise primary supervision over the administration of the trust, and one or more U.S. persons must have authority to control all substantial decisions of the trust. Any trust that does not meet both tests is a foreign trust. 

The word “all” in the control test carries considerable weight. Substantial decisions are the core fiduciary calls. Whether to distribute, when, how much, and to whom. Whether to litigate or settle. Whether to remove and replace a trustee. How to invest. A single non-U.S. person holding a single one of those powers can move the trust across the border. 

Be aware of the automatic migration clause. Plenty of older asset protection templates include language that shifts the trust offshore the moment a creditor files suit in a U.S. court. Drafters like the clause because it looks protective. The regulations treat it very differently, because a trust subject to that kind of provision can fail the court test from the day it was signed

The successor trustee problem is quite common. A trust can be drafted in the United States, funded by a U.S. person, and administered here for years, and still become a foreign trust without anyone signing a new document. All it takes is for the named successor trustee to be a non-U.S. person. The control test asks who holds authority over substantial decisions at any given moment, not who held it at the time of signing. When the U.S. trustee dies, resigns, or moves abroad and a foreign successor steps in automatically under the terms of the instrument, U.S. persons no longer control all substantial decisions, and the trust becomes foreign as of that date.

The regulations give an illustration worth reading before signing anything. A trust that satisfies the court test has three fiduciaries deciding by majority vote. Two are U.S. citizens, and one is a nonresident alien. The instrument names a successor fiduciary who is also a nonresident alien. One of the U.S. fiduciaries dies, the successor takes over automatically, and control over substantial decisions is no longer in U.S. hands. 

There is relief, and it runs on a clock. Where the change in a person holding power over a substantial decision is inadvertent, such as the death, resignation, or change of residence of a U.S. trustee, the trust has 12 months from the date of the change to correct it. The correction can go either way, by changing who controls substantial decisions or by changing where those people are resident. Act within the window and the trust keeps its domestic status without interruption. Miss it and residency changes as of the date of the inadvertent change, which means retroactively to the day the trustee died rather than the day someone noticed. 

Deliberately naming a foreign individual as successor trustee is not an inadvertent change, so the 12-month cure is not available. And a trust that has quietly been foreign for several years usually has exposure to unfiled Forms 3520-A.

Build The Structure For Protection, Not For Concealment

A foreign trust used for genuine wealth protection should have real non-tax substance behind it. In practice that means an independent trustee who actually exercises discretion, administration that genuinely happens in the chosen jurisdiction, separate books and bank accounts, distributions that are documented as distributions, and no habit of paying the settlor’s personal expenses out of trust funds.

The test I apply is simple. If the trustee declined a distribution request, would that be the end of the conversation? If the honest answer is no, then the trust is not doing what the documents say it does, and no amount of jurisdiction shopping will fix that.

Concealment is another issue associated with some trusts. The IRS treats abusive trust arrangements as a standing enforcement priority and specifically warns that offshore structures are promoted to obscure true ownership and control. A structure that depends on the IRS not discovering it is not a plan.

Expect Grantor Trust Treatment When A U.S. Person Funds The Trust

This is the point at which clients are most often surprised, because it undoes the assumption that funding the trust means giving the assets away.

Under section 679, when a U.S. person directly or indirectly transfers property to a foreign trust, that transferor is generally treated as the owner of the portion of the trust attributable to the transferred property, provided the trust has a U.S. beneficiary. The statutory exceptions are narrow. Transfers by reason of the transferor’s death, and transfers for consideration of at least fair market value.

Section 679 is deliberately broader than the ordinary grantor trust rules. It applies even where the transferor retained none of the powers or interests under sections 673 through 677 that would otherwise create grantor trust status. Giving up control does not get you out of it.

The U.S. beneficiary question is also broader than most people expect. A foreign trust is generally treated as having a U.S. beneficiary unless its terms both prevent income or corpus from being paid to or accumulated for a U.S. person during the year and prevent any U.S. person from benefiting if the trust terminated that year. Contingent interests count. A remote remainder beneficiary who holds a U.S. passport is sufficient.

Where section 679 applies, the trust’s income flows onto the U.S. owner’s personal return. The client, who thought the structure had removed income from the U.S. tax base, is now reporting all of it and has annual trust reporting on top of that.

Gain On Funding, And An Everything That Happens Afterward

Clients almost always ask whether moving assets into the trust will trigger tax. The general rule sounds alarming, the exception that follows it is broad, and the real planning lives in understanding how the two fit together and when the exception runs out.

The General Rule

Section 684 treats a transfer of property by a U.S. person to a foreign trust as a sale or exchange for fair market value, with gain recognized to the extent that fair market value exceeds adjusted basis. The regulations then make the arithmetic worse in two ways. Losses are not recognized, and losses on depreciated assets cannot be netted against gains on appreciated assets transferred at the same time. 

Why Most Funding Transfers Do Not Actually Produce Gain

This is the part that gets missed by anyone who stops reading at section 684(a). Gain is not recognized to the extent that any person is treated as the owner of the trust under section 671. That exception sits in section 684(b) and is repeated in Treas. Reg. section 1.684-3(a).

Now read it alongside section 679. A U.S. person who funds a foreign trust with a U.S. beneficiary is treated as the owner of the portion funded. Because that person is an owner under the grantor trust rules, the section 684(b) exception applies, and there is no gain on funding.

So for the most common fact pattern, a U.S. settlor funding a foreign trust for U.S. family members, the answer to “does this transfer trigger gain?” is generally no. The two provisions clients find most alarming, sections 679 and 684, largely cancel each other out at the funding stage. What section 679 does instead is keep the trust’s income on the settlor’s own Form 1040, year after year.

When Gain Does Arise

The exception depends entirely on someone being treated as the owner. Remove that and the deemed sale reappears. Four common situations:

• No U.S. beneficiary. If the trust has no U.S. beneficiary, section 679 does not apply, nobody is treated as owner, and the exception is unavailable. Funding is an immediate taxable deemed sale. This is the classic case of a U.S. person providing for family who live abroad.
• Loss of grantor trust status during life. If a portion of the trust ceases to be treated as owned by the U.S. person, that person is treated as transferring the assets of that portion to a foreign trust immediately before the change. Gain is recognized at that point, including on appreciation that accrued in the intervening years.
• Death of the U.S. grantor. Death ends grantor trust status, and the deemed transfer is treated as occurring immediately before death. Because it lands immediately before, section 1014 does not automatically rescue it. There is an exception where the property is included in the decedent’s estate and the transferee’s basis is determined under section 1014(a), in which case no gain is recognized. Whether that inclusion exists is a question to settle while the client is alive.
• Outbound migration of a domestic trust. If a U.S. person funded a domestic trust, the trust later becomes foreign, and neither trust is treated as owned by anyone under the grantor trust rules, the trust is treated as transferring all of its assets to a foreign trust and must recognize gain. 

The Filing Burden Is The Price Of Admission

Foreign trust planning is paperwork heavy. Section 6048 sets out the reportable events. Creation of a foreign trust by a U.S. person. A direct or indirect transfer of money or property to a foreign trust by a U.S. person. Certain deaths involving foreign trusts. Notice is generally required on or before the 90th day after the reportable event, in the manner the IRS prescribes. That 90-day clock starts at formation or funding, long before anyone is thinking about next April’s return.

A U.S. person treated as the owner of a foreign trust carries two obligations. Provide the prescribed information about the trust, and make sure the trust itself files an annual return giving a full accounting of its activities and furnishes the required statements to U.S. owners and U.S. beneficiaries. Form 3520-A is that annual information return for a foreign trust with at least one U.S. owner, and responsibility for seeing that it gets filed rests on the U.S. owner rather than on the foreign trustee.

That allocation of responsibility catches people out. If the offshore trustee simply does not file, the U.S. owner may need to complete a substitute Form 3520-A and attach it to their own Form 3520 in order to avoid the penalty for the trust’s failure. “The trustee did not send me anything” is not a defense. It is a reason to build annual trustee reporting into the trust agreement and the fee arrangement from the outset.

U.S. beneficiaries have their own obligation. Direct and indirect distributions from a foreign trust must be reported, and indirect covers more ground than most beneficiaries assume, including certain uses of trust property and loans.

Do Not Treat Form 8938 And The FBAR As Optional Extras

These are separate regimes with separate thresholds, and satisfying one says nothing about the others.

Form 8938 reports specified foreign financial assets. Section 6038D requires an individual holding an interest in such assets to attach the required information to the annual income tax return once aggregate value exceeds the applicable threshold. 

Penalty Exposure Is Large Enough To Design Around

For failures under section 6048, the section 6677 penalty is generally the greater of $10,000 or 35 percent of the gross reportable amount, plus a further $10,000 for each 30-day period or fraction of a period that the failure continues more than 90 days after the IRS gives notice. For annual foreign trust owner reporting under section 6048(b), the 35 percent figure drops to 5 percent.

What counts as the gross reportable amount depends on which failure occurred. It may be the gross value of property involved in a reportable event, the gross value of trust assets treated as owned by the U.S. person, or the gross amount of distributions. 

Reasonable cause is available, and it is worth taking seriously. Foreign secrecy laws are expressly not reasonable cause, so a trustee’s refusal to hand over information because local law prohibits it will not help. Contemporaneous records showing what the client asked for, when, and what they were told will.

Form 8938 carries its own regime. A failure to disclose draws $10,000, with additional $10,000 increments if the failure continues after notice, capped at $50,000 for each failure. The reasonable cause exception requires an affirmative showing and is judged on all the facts and circumstances.

Two developments are worth knowing about. On the enforcement side, the courts have shown little sympathy. On the relief side, the IRS changed course in late 2024 and stopped automatically assessing penalties on late-filed Forms 3520 and 3520-A before reviewing any reasonable cause statement attached to the filing. That is a meaningful improvement over the old assess-first approach, and it makes one point of practice essential. If a form is going in late, the reasonable cause statement goes in with it, not afterward in response to a notice.

The Bottom Line

Foreign trusts can do real work for families with genuine cross-border lives. They can segregate assets, provide for succession across jurisdictions, and give a professional trustee the mandate to administer wealth over generations. What they cannot do is hide anything, and they cannot be bolted together first and reported later.

The safest planning posture is unglamorous. Use the trust for real administration and real asset protection objectives, keep control and record-keeping consistent with what the documents say, report the structure completely and on time, and price the penalty regime into the design before the first asset moves. Do that, and the structure holds up. Skip it and the paperwork will find you eventually, usually with a penalty attached that has nothing to do with how much tax was ever at stake.

If you are considering a foreign trust, already hold an interest in one, or have discovered that a structure you assumed was domestic is not, the analysis is worth doing properly and early. Correcting a classification or reporting problem voluntarily is always cheaper than responding to a notice.

After hardly 40 days, the Government has now decided to amend its new cost base indexation laws to allow Australian expats (and other non-residents) to have the benefit of the cost base indexation on a proportionate basis from 1 July 2027.

On 26 June 2026, the Government legislated and introduced Section 114.25 ITAA 1997 which reads as follows:

INCOME TAX ASSESSMENT ACT 1997 – SECT 114.25

Residency requirements for individuals for indexation to be included in a cost base under subsection 110 – 36(1A)

 (1)  This section sets out requirements for indexation to be included under subsection   110 – 36(1A) in the * cost base of a * CGT asset for the purposes of working out your * capital gain from a * CGT event happening in relation to the * CGT asset if:

 (a)  you are an individual; and

 (b)  the CGT event happened while you were holding the CGT asset (as a result of earlier * acquiring it).

Note:  This section applies for working out a capital gain you make from directly holding the asset. A similar result arises for any capital gain you make indirectly as a beneficiary of a trust (see Subdivision 115 – C, in particular subsections   115 – 225(4) and (5)).

 (2)  You must be neither a foreign resident nor a * temporary resident at any time during the period (the testing period) :

 (a)  starting on the later of 1   July 2027 and the day of * acquiring the * CGT asset; and

 (b)  ending on the day the * CGT event happens.

The Problem: Complete Loss Of Indexation

The effect of Section 114.25 is that if a person is a non-resident at any time during their ownership period of an Australian investment property, they will not be able to benefit from cost base indexation at all – regardless of how long they may have owned the property while living in Australia.

We highlighted this inequity in a tax seminar held for members and invitees of the American Australian Association in New York on 16 July 2026.

We are pleased that the Government has now proposed to address this issue.

Legislation As “Beta Code”?

Curiously, the Explanatory Memorandum which introduced the Tax Reform Act 2026 flagged that

“Future amendments may be considered in relation to how entities that are resident for only part of the period they hold a CGT asset …may access indexation. “

That begs the question: Why did the Government legislate in this manner in the first place if they knew there was an equity issue that would need to be addressed?

It is disappointing to see this legislative approach, which wastes valuable time and resources and fuels uncertainty.

New tax rules should not be treated as some form of ‘beta code’, released for user acceptance testing with bug fixes in the form of amendments.

Since the equity issue here was surely known at out the outset it, these issues would have been far better addressed as part of exposure draft legislation rather than being rush through with all the other Budget changes.

RIP Section 114.25 ITAA 1997 – alive for hardly 40 days and already ready to be cast aside!

“O, ill-fated tax Section, whither goest thou? To become an irrelevancy after not having inconvenienced a single person!”

What The Proposed Amendments Mean For Expats

The proposed removal of Section 114.25 will mean that:

• a Departing Australian moves overseas and becomes a non-resident, they will NOT lose the benefit of cost base indexation completely (on property they directly own).
• a Returning Australian can also benefit from cost base indexation upon returning, on a proportionate basis.

Trust Ownership

We caution that this amendment only addresses the equity issue where a person directly owns real estate and changes tax residency.

It does not deal with the situation where a beneficiary of an Australian trust changes tax residency and the asset of the Trust is sold.

The Government is aware of this, given its latest comments as follows:

‘Further consideration is being given to determining appropriate outcomes for taxpayers who change their residency status and how make capital gains indirectly through a trust.’ (paragraph 1.92 Exposure Draft Explanatory Memorandum Treasury Laws Amendment (Tax Reform No. 3) Bill 2026: CGT Adjustments (Tranche 2).

It would be straightforward to permit a non-resident to benefit from cost base indexation to the extent they have been a resident of Australia at some point during the Trust’s ownership of the asset.

That approach to apportionment for trust level capital gains was already perfectly operational under the previous 50% CGT discount rules.

Whether the Government extends this reasonable approach to trust beneficiaries remains to be seen. Will they or won’t they (allow it) – that is the question.
