"I'll just set up a Singapore Pte Ltd to save tax" is one of the most common — and most expensive — ideas an Australian-resident business owner brings to an accountant. Three separate sets of rules usually defeat it: the controlled foreign company rules in Part X of ITAA 1936, the central management and control residency test, and the permanent establishment rules in the relevant tax treaty. Used together they catch most genuine cases. They were strengthened by the Multilateral Instrument that Australia signed and ratified in 2017–2019, and the ATO has consistently identified offshore structuring as a compliance focus. Before you incorporate offshore, understand which rules apply to your situation and what they actually cost.
The three rules that catch most offshore structures
An Australian-resident individual who incorporates a company overseas typically faces three Australian tax rules simultaneously. Any one of them can pull the foreign company's income back into Australian assessable income:
1. The controlled foreign company (CFC) rules in Part X of the Income Tax Assessment Act 1936. Attributes "tainted" (broadly, passive) income of a foreign company controlled by Australians back to Australian shareholders each year, regardless of whether dividends are paid.
2. The central management and control (CM&C) residency test in section 6 of ITAA 1936, as interpreted in Bywater Investments Ltd v Commissioner of Taxation [2016] HCA 45 and ATO ruling TR 2018/5. If high-level decisions are made in Australia, the foreign company is itself an Australian tax resident and taxed on worldwide income at the company rate.
3. Permanent establishment (PE) rules in the relevant double tax treaty. If the foreign company has a PE in Australia — broadly, a fixed place of business or a dependent agent habitually concluding contracts there — Australia gets a taxing right over the profits attributable to that PE. The MLI (signed 2017, in force for many Australian treaties from 2019 onwards) made the agent-PE rule materially harder to avoid.
For most Australian-resident owners running a business from Australia through a foreign company, at least one of these three rules will apply. Often two or three apply at once. The right question is not "can I avoid Australian tax with an offshore company" but "what does the actual tax position look like, and is the offshore structure worth the compliance and audit cost".

Rule 1 — The CFC rules in Part X ITAA 1936
Part X is Australia's anti-deferral regime for offshore companies. The architecture has three layers:
Layer 1 — Is the foreign company a CFC? A foreign company is a CFC under sections 340–343 of ITAA 1936 in three main cases:
- Five or fewer Australian residents (with their associates) hold at least 50% of the company (the "5-or-fewer test"); or - A single Australian resident (with their associates) holds at least 40% (the "single-entity test"), unless another entity not associated with them controls the company; or - Australian residents collectively have de facto control (the "de facto control test").
A wholly Australian-owned offshore company is always a CFC.
Layer 2 — Are you an attributable taxpayer? Generally, an Australian resident with an attribution interest of 10% or more in the CFC. The attribution interest looks through chains of companies; you can be an attributable taxpayer indirectly.
Layer 3 — How much is attributed? The attributable taxpayer includes a share of the CFC's "attributable income" in their Australian assessable income for the year. Attributable income is calculated under Division 7 of Part X and depends on:
- The CFC's jurisdiction classification — "listed country" (broadly, comparable-tax jurisdictions on a regulated list) or "unlisted country" (everything else, including most low-tax jurisdictions). - Whether the CFC passes the active income test — broadly, at least 95% of the CFC's gross turnover is "active" income (genuine business operations, not passive returns). A CFC that passes the active income test attributes only specific narrow categories of income. - For CFCs that fail the active income test, attribution applies broadly to all "tainted income" — passive income such as interest, dividends, rent, royalties, certain capital gains, related-party services and sales income.
In simple terms: a genuine offshore operating business (real staff, real premises, real customers, mainly active turnover) generally has limited current-year attribution. A passive holding company in a low-tax jurisdiction attributes most or all of its income to its Australian controllers each year, with credit for any foreign tax paid.

Rule 2 — Central management and control: when a foreign company is Australian-resident
Section 6 of ITAA 1936 treats a foreign-incorporated company as an Australian tax resident if its central management and control is in Australia and it carries on business. The High Court's decision in Bywater Investments Ltd v Commissioner of Taxation [2016] HCA 45 and the ATO's follow-up ruling TR 2018/5 made two practical points unavoidable:
- The CM&C test focuses on where the high-level strategic and policy decisions are actually made — not where the board nominally meets, not where directors live, not where the company is incorporated. - A foreign company is taken to be carrying on business in Australia for residency purposes if its CM&C is in Australia. There is no separate "carrying on business" hurdle.
For an Australian-resident individual who is the only director of a Singapore, Dubai or Delaware company, the CM&C will almost always be in Australia. Routing the formal board meetings through a serviced office overseas does not help if the real decisions — investment, hiring, contract approval, banking — are taken in Australia.
If the company is Australian tax resident under CM&C, it is taxed on its worldwide income at the Australian company rate (25% for base rate entities, 30% otherwise) and the CFC rules effectively do not apply because the company is no longer a CFC at all.

Rule 3 — Permanent establishment risk under tax treaties
Even if the foreign company manages to be non-resident in Australia, it can still be taxed in Australia on profits attributable to a permanent establishment in Australia. Most Australian double tax treaties broadly follow Article 5 of the OECD Model: a PE includes a fixed place of business (office, branch, factory) and a dependent agent who habitually concludes contracts on behalf of the company.
The Multilateral Instrument (MLI), which Australia signed in 2017 and is in force for most major treaties from 1 January 2019 (income tax), substantially broadened the dependent agent PE rule. Under the MLI's Article 12, an agent who "habitually plays the principal role leading to the conclusion of contracts that are routinely concluded without material modification" by the foreign company creates a PE — even if the contracts are formally signed offshore. The change was designed to defeat exactly the "commissionaire" structures that earlier multinationals used.
Practically, this means an Australian-resident individual who:
- Operates from their Australian home or office; - Materially negotiates and executes the foreign company's contracts with customers; or - Has a sales team or contractors in Australia who do so,
creates a high risk of an Australian PE for the foreign company. The foreign company would then need to lodge an Australian tax return for the PE's profits.

Other rules that bite — transferor trusts, foreign hybrid entities, transfer pricing
Transferor trust rules in Division 6AAA of ITAA 1936 attribute the income of certain foreign trusts back to Australian transferors. If you "fund" a foreign structure (including via a loan or share subscription used to capitalise an offshore trust), these rules can apply alongside or instead of the CFC rules.
Foreign hybrid entity rules in Subdivision 830 (and the more recent hybrid mismatch rules in Division 832 ITAA 1997) deal with entities like US LLCs that are taxed as flow-throughs in their home country but as companies in Australia. Outcomes are commonly counter-intuitive.
Transfer pricing in Division 815 of ITAA 1997 requires any cross-border related-party dealings (loans, services, IP licensing) to be at arm's length. The ATO's Practical Compliance Guideline PCG 2017/4 and successors apply colour-coded risk ratings to common structures.
Diverted Profits Tax at 40% on diverted profits, in force from 1 July 2017 (Tax Laws Amendment (Combating Multinational Tax Avoidance) Act 2017). Designed for large groups but a useful illustration of the policy direction.

When does an offshore company actually make sense?
There are situations where an offshore company is the right structure:
- You have a genuine offshore operation with real staff, real premises and real local customers in the foreign jurisdiction. The active income test in Part X then limits attribution to specific narrow categories. - You have local market access or regulatory requirements (financial services licensing, e-commerce platform rules, government contracts) that mandate a local entity. - You are not currently an Australian tax resident. The CFC and CM&C rules apply to Australian residents — non-residents are outside their direct reach (though there are anti-conduit rules). - You are using a structure with a clear non-tax purpose — succession planning, asset protection, joint venture with overseas partners — and the tax outcomes have been modelled honestly, not assumed away.
The wrong reason: "I read on a forum that Singapore has 17% tax". Singapore's company rate is largely irrelevant if the Australian CFC rules attribute the income to you anyway, or if CM&C makes the company an Australian tax resident at the Australian rate.

What to do before you incorporate offshore
- Get written advice from a TPB-registered tax agent on the CFC, CM&C and PE positions for the specific structure you have in mind. A 90-minute consultation that costs $500–$1,500 will save vastly more in unwound structures or audit exposure. - Document the business purpose independently of tax. The ATO's general anti-avoidance rule (Part IVA) overlays everything else and asks whether the dominant purpose of the arrangement was obtaining a tax benefit. A clear commercial reason matters. - Plan for the compliance load. CFC attribution calculations are technical and annual. Foreign income tax offsets (Division 770 ITAA 1997) require careful tracking of foreign tax paid. Transfer pricing documentation is a separate exercise. - Run the numbers honestly. Total Australian tax + foreign tax + advisory fees + compliance time on a CFC structure often exceeds the tax payable on the same business operated through an Australian Pty Ltd. Pricing transparency is brutal.

FAQ
Q: I'm Australian but moving to Dubai for two years. Can my Dubai company avoid Australian tax during that period? A: If you genuinely cease to be an Australian tax resident on departure, the CFC rules will not generally attribute income to you while non-resident — but CGT event I1 is triggered on the way out (see our companion article). The CM&C test still applies, so if Australian-resident relatives or co-directors run the company day-to-day, the foreign company may itself be Australian-resident. Get the residency view in writing first. Q: Are there safe-harbour jurisdictions where the CFC rules don't apply? A: There are "listed countries" (under the Income Tax Regulations 1936) — broadly comparable-tax jurisdictions where the CFC rules apply with much narrower attribution. The list includes Canada, France, Germany, Japan, New Zealand, the UK and the US. Even for a listed-country CFC, certain "eligible designated concession income" is attributed. Singapore, Dubai (UAE), Hong Kong and BVI are unlisted countries — full Part X attribution applies. Q: Can I just hold the foreign company through a discretionary trust to dilute control? A: The CFC rules look through trusts in identifying attributable interests, and the transferor trust rules in Division 6AAA can attribute foreign trust income back to Australian transferors. Inserting a trust does not solve the underlying issue and often makes the compliance worse. Q: What about an Estonian e-Residency company or a US LLC? A: Both are popular online but technical. An Estonian OÜ is a company for Australian purposes and falls inside the CFC rules. A US single-member LLC is generally taxed as a foreign hybrid in Australia under Subdivision 830 ITAA 1997 — meaning its income is taxed currently in the Australian member's hands as if the LLC were a partnership. The "no US federal tax for non-US owners" claim repeated on social media is irrelevant to your Australian tax position. Q: Does Part IVA apply to a small business setting up offshore? A: Yes, in principle. Part IVA applies where the dominant purpose of an arrangement is to obtain a tax benefit. The ATO has used Part IVA against small-scale offshore structures where the commercial substance is weak. Document the commercial purpose, model the actual tax outcomes, and avoid arrangements where the only meaningful benefit is the tax saving.---
