What the Bywater Case Means for Australian Business Owners With Offshore Structures

Introduction

Many Australian business owners assume their foreign-incorporated company’s tax residency follows the board — where the directors sit & where the minutes are signed. The Bywater Investments Limited & Ors v Commissioner of Taxation [2016] HCA 45 (‘Bywater‘) decision exposed that assumption directly: it was not where the directors were located that counted — it was where the real decisions were being made.

This article explains what the High Court found, why the Commissioner of Taxation now uses Bywater as the benchmark for examining offshore corporate tax residency, & what the decision means for your structure.

The Case That Changed How the ATO Looks at Offshore Companies

Australian business owners with offshore structures once operated under a framework where formal governance — where directors sat & where board minutes were signed — carried significant weight with the ATO. Under Taxation Ruling TR 2004/15 (‘TR 2004/15’), if the paperwork showed decisions were made offshore, the structure was rarely questioned.

The High Court’s unanimous decision in Bywater replaced that framework. It is not where the directors are located that counts — it is where the real decisions are being made. A structure that looks clean on paper but fails on substance is precisely what Bywater exposed.

What Happened in Bywater & What the High Court Found

The Real Story Behind the Offshore Setup

The Bywater case exposed a structure where the real business ran from Sydney while the formal governance sat offshore. Four foreign-incorporated companies sat at the centre of the case:

• Three — Bywater Investments Ltd, Chemical Trustee Ltd & Derrin Brothers Properties Ltd — had formal directors based in Switzerland, led by Peter Borgas.
• The fourth, Hua Wang Bank Berhad, was incorporated in Samoa & administered through Asiaciti, a corporate services firm.

Behind every entity was Vanda Gould, a Sydney-based accountant who made every real commercial decision — what ASX-listed shares to buy & sell, investment policy, & general business direction — from Australia, without the offshore directors’ involvement. The formal governance structure was a shell, & the real business ran from Sydney the whole time.

The High Court’s Unanimous Finding

The High Court unanimously dismissed all four appeals, finding the companies were Australian residents for income tax purposes. The basis was paragraph (b) of subsection 6(1) of the Income Tax Assessment Act 1936 (Cth) (‘ITAA 1936‘) because their central management & control was in Australia.

The Court confirmed a long-established principle: a company’s residence is a question of fact determined by the course of its business & trading, not by the documents establishing its formal structure. 

Where directors abrogate their decision-making to someone else & only meet to rubber-stamp decisions already made in Australia, the formal structure does not control the outcome. It was not where the directors were located that counted — it was where the real decisions were being made.

Directors Who Rubber-Stamped Instead of Decided

The High Court found that Borgas & the Asiaciti directors were not exercising genuine independent judgment. Their role was to record & implement Gould’s instructions — made from Sydney — in a mechanical fashion.

This finding goes to the heart of what central management & control actually means. Directors who implement decisions made by someone else, rather than exercising genuine independent judgment, do not constitute CMC offshore. The Court confirmed that CMC may be exercised by persons without any legal authority to manage or control a company. 

If you are the one calling the shots from Australia, the fact that offshore directors sign the paperwork does not protect the structure.

Board Minutes That Did Not Match Reality

Board meetings were formally recorded as taking place in Switzerland, but the ATO looked past the minutes & examined key evidence, such as: 

• Correspondence; 
• email chains, and 
• the actual sequence of events. 

What emerged was clear: the real decisions were made by Gould in Sydney before they were ever recorded offshore.

This is where the evidentiary failure becomes catastrophic for a structure. Paperwork that contradicts the actual course of business is not a shield — it is evidence of a problem. When board minutes do not reflect genuine deliberation that happened offshore, they shift the structure from low-risk into an exposed position that the ATO will examine in detail.

The Controlling Mind Operating From Sydney

Gould held no formal director title in any of the four companies. Yet, he was the person whose judgment they actually ran on. He maintained the key relationships, made the real calls on what shares to trade, & directed the entities’ operations from Sydney.

The High Court confirmed that CMC is determined by the reality of what happens, not by legal formalities or restrictions on who may exercise it. The question after Bywater is not who appears as director on the register, but whose judgment the company’s business actually depends on.

Why Bywater Is the Benchmark the ATO Now Uses

The Shift From TR 2004/15 to TR 2018/5

The ATO’s framework for assessing where a foreign company is managed has been reset. Before Bywater, the Commissioner’s position in TR 2004/15 gave weight to where directors were located & where board meetings took place, allowing a foreign-incorporated company to argue its central management & control was offshore.

The High Court dismantled that approach, & the ATO recognised that the position in TR 2004/15 “can no longer be sustained”. It was replaced with Taxation Ruling TR 2018/5 (‘TR 2018/5’), which codifies the Bywater principle: central management & control is determined by the substance & reality of where high-level decisions are made, not by formal governance structures. 

Australian business owners who relied on offshore directors & clean board minutes as their primary defence now face a fundamentally different assessment standard.

How Practical Compliance Guideline PCG 2018/9 (‘PCG 2018/9’) Risk-Assesses Offshore Structures

For Australian business owners with offshore entities, the quality of board records is now the gatekeeper. PCG 2018/9 sets out how the ATO applies the CMC test to foreign-incorporated companies. Its centrepiece is a board minute safe harbour: where a company maintains comprehensive, accurate minutes detailing where & by whom high-level decisions were made, the ATO will accept those records as primary evidence of CMC location.

Where minutes are incomplete, not kept, or shown to be false, the ATO examines other evidence — pre-meeting papers, emails, correspondence, & oral statements from decision-makers. This is the same forensic approach the Commissioner used in Bywater. A structure that cannot produce genuine, contemporaneous board records is effectively inviting the ATO to reconstruct where decisions were really made.

The Three Questions the ATO Now Asks

The Bywater principles distil into three questions the ATO now applies to offshore structures:

1. Are the offshore directors genuinely independent, or are they receiving instructions from Australia? Directors who implement decisions made by someone else, rather than exercising genuine independent judgment, do not constitute CMC offshore.
2. Do the board minutes reflect genuine deliberation, or do they record decisions already made in Australia?
3. Where does the controlling mind actually sit — whose judgment does the company’s business depend on?

A structure that cannot answer all three satisfactorily falls into the ATO’s moderate or high-risk zone. At that point, the offshore entity that looked compliant on paper has been fully exposed, & the Australian business owner faces the outcome Bywater was designed to prevent — Australian tax residency with all its consequences.

Would the Structure Survive the Same Scrutiny?

Who Actually Makes the Strategic Decisions?

The first question to ask is who really decides:

• what shares to buy & sell;
• what the investment policy is; and
• what commercial direction the company takes.

In Bywater, the answer was Vanda Gould — a Sydney-based accountant with no formal director title.

If the answer for your structure involves the Australian owner giving direction to offshore directors, that is exactly the pattern the High Court examined. Directors who implement decisions made by someone else, rather than exercising genuine independent judgment, do not constitute CMC offshore.

Are the Offshore Directors Truly Independent?

The High Court found that the directors in Switzerland & Samoa had surrendered their decision-making authority entirely. They did not push back, ask questions, or reach different conclusions — they simply recorded & implemented Gould’s instructions.

Ask yourself whether your offshore directors could explain the commercial reasoning behind a major decision if the Commissioner of Taxation’s office asked. If they are only receiving & acting on instructions from Australia, the Bywater standard is not met — it was not where the directors were located that counted, but where the real decisions were being made.

Do the Board Minutes Reflect Genuine Deliberation?

Under the PCG 2018/9 safe harbour, comprehensive board minutes are treated as prima facie evidence of where central management & control is located — but only if they reflect what actually happened.

Minutes that record decisions already made in Australia are not a defence — they are evidence of the problem.

Where Does the Controlling Mind Really Sit?

The concept the High Court embedded into Australian tax law is simple: look past the register of directors & ask whose judgment the company actually runs on. In Bywater, Gould maintained the key relationships with bankers, advisers, & major clients — he was the person everyone deferred to when a material decision needed to be made.

If the Australian owner is the person whose judgment the business actually runs on, CMC is likely in Australia. The formal title on the company register does not determine the answer — the course of the company’s business does.

Who Conducts & Approves Material Negotiations?

A practical indicator the High Court examined was where the person who conducts & approves material commercial negotiations is physically located. In Bywater, Gould handled all significant negotiations from Sydney — the offshore directors were not involved in any meaningful commercial discussion.

If your offshore company’s major contracts, financing arrangements, or client negotiations are led from Australia, the structure is exposed. The ATO will ask where the negotiating party was sitting when the deal was struck — & that location can anchor CMC regardless of where the board later ratifies it.

The Structures Most at Risk & the Warning Signs

Nominee Director Arrangements Where the Australian Owner Remains Central

A Singapore company with a local nominee director, where the Australian business owner directs all material decisions by email, is the clearest Bywater risk pattern. The nominee exists to satisfy incorporation requirements — not to exercise genuine central management & control.

The structure fails the moment the offshore director cannot demonstrate independent judgment & genuine deliberation, regardless of where that director is physically located. Directors who implement decisions made by someone else, rather than exercising genuine independent judgment, do not constitute CMC offshore.

A company’s residence is a question of fact — not a question of what its documents say. This is where an offshore company that looks independent on paper still ends up fully inside the Australian tax net.

Holding Companies Managed Remotely From Australia

Offshore holding companies whose Australian owner manages all decisions from Australia face direct Bywater exposure, regardless of whether they are in the BVI, Cayman, or Singapore. Attending quarterly board meetings by video call from Sydney does not shift central management & control offshore.

If the Australian owner is the person whose judgment the holding company’s operations depend on, CMC is likely in Australia regardless of where the video call originates. The High Court in Bywater made clear that where a company’s CMC is located is a question of fact determined by the reality of what happens.

In practice, this means the structure does not deliver the offshore tax outcome the owner is relying on, even if formal board minutes suggest otherwise.

Structures Where the Paperwork Is Clean, but the Substance Is Not

The most common Bywater risk is a structure established with proper documentation at formation, whose governance arrangements have gradually drifted back toward Australian control. The Australian owner becomes increasingly central, the offshore directors become increasingly passive, & the gap between what the minutes record & what actually happens widens. The structure looks clean on paper but fails on substance.

As discussed above, the ATO examines the reality of where high-level decisions are actually made, not the formal legal structures.

However, minutes that record decisions already made in Australia do not protect the structure — they become evidence of the problem. In that scenario, the very documentation meant to support the structure instead confirms that CMC remains in Australia.

What a Bywater-Proof Structure Actually Looks Like

What Genuine CMC Offshore Actually Requires

A structure that genuinely satisfies the Bywater standard turns on where high-level decisions are actually made, not on formal governance documents. Offshore directors must do more than mechanically implement instructions from an Australian owner. They must:

• understand the business;
• engage with board papers;
• ask genuine questions; and
• exercise independent judgment.

Board meetings also need real agendas, real discussion, & minutes that reflect what actually occurred. The ATO examines the substance & reality of where high‑level decisions are made rather than formal governance structures.

Central management & control is assessed in each income year against the facts as they exist in that year. A structure that was sound at formation does not stay that way without active, ongoing maintenance.

Why Professional Advice Is Essential Here

The Bywater standard is not something an Australian business owner can self‑diagnose by reviewing their paperwork. Many owners genuinely believe their foreign‑incorporated company is compliant because the incorporation documents & board minutes appear in order. However, the ATO examines the reality of where the controlling mind actually sits, not just the formal record.

A specialist in Australian international tax law can review your actual governance arrangements against the Bywater indicators, identify where the structure is exposed, & advise on what genuine remediation requires. Doing nothing is what creates major issues. A structure that looks clean on paper but fails on substance is exactly the kind of arrangement the High Court dismantled in Bywater.

Conclusion

The Bywater decision established that corporate tax residency is not about where directors are located — it is about where the real decisions are made. A structure that looks compliant on paper but fails on substance is exactly what Bywater dismantled, & getting the substance right is what separates a defensible offshore structure from an expensive rebuild.
