Buying a Business Overseas as an Australian Expat: The Tax Side Nobody Warns You About

Buying a business in another country is a genuinely exciting move. New lifestyle, new market, a proper adventure with a profit-and-loss statement attached. And there’s plenty of sensible groundwork to do before you sign anything: understanding the local infrastructure, the political and economic stability, the way business actually gets done, and the culture of the people you’ll be working with every day. All of that matters, and getting to know the locals rather than just the expat bubble is genuinely good advice.

But here’s the thing most “things to consider” lists gloss over in a single line at the bottom. The tax side. And not just the foreign country’s tax, the Australian tax consequences, which have an unhelpful habit of following you across the border and turning up when you least expect them. We’re registered tax agents, not business brokers or migration agents, so we’ll leave the choosing of the business to you and your advisers. What we can do is walk you through the Australian tax traps that catch Australians buying businesses abroad, because they’re the ones that quietly cost the most.

It all starts with your residency

Before anything else, work out your Australian tax residency, because it determines how much of this even applies to you. If you remain an Australian tax resident (and simply moving overseas doesn’t automatically end that, it depends on your circumstances and ties), then you’re generally taxed in Australia on your assessable income from all sources, both Australian and foreign. That can include salary, dividends, trust distributions, attributed foreign-company income, and in some cases income connected with your shiny new overseas business. A low tax rate in the country you’ve moved to doesn’t change your Australian position; it just changes how much foreign tax you may have paid before Australia has its turn.

If you’ve genuinely ceased to be an Australian tax resident, Australia generally steps back from your foreign business income, but ceasing residency is its own careful exercise with its own consequences. Either way, residency is the foundation stone, which is why we have a whole guide on being an Australian resident for tax purposes. Sort that out first.

Leaving Australia can trigger an exit tax before you even buy

If buying the overseas business is part of a broader move offshore, don’t skip the Australian exit tax. When you cease Australian tax residency, CGT event I1 can treat you as having disposed of many of your non-taxable-Australian-property CGT assets at market value on the day you leave.

That can include shares, options, crypto, foreign assets, founder equity and, depending on timing, interests connected with the overseas business. You may be able to choose to disregard the deemed gain or loss, but that keeps the relevant assets inside the Australian CGT net until you actually sell or become an Australian resident again. So the timing genuinely matters: buying before leaving, leaving before buying, holding personally or through a company, and making or not making the CGT event I1 choice can all produce different outcomes. This isn’t the bit to sort out from the departure lounge while boarding is open.

The trap that catches almost everyone: running a foreign company from Australia

Here’s the one that genuinely blindsides people. You buy a business overseas, structure it as a foreign company, and assume that because it’s incorporated in another country, it’s automatically outside the Australian tax net. Then the real decisions get made from Australia, and the wheels start wobbling.

Under Australian law, a company that isn’t incorporated here can still be an Australian tax resident if it carries on business in Australia and has its “central management and control” in Australia. A foreign company can also be resident if it carries on business in Australia and its voting power is controlled by Australian-resident shareholders. So the label on the incorporation certificate isn’t the whole story; the ATO is deeply unmoved by stationery.

Following the High Court’s decision in the Bywater case, and the ATO’s view in Taxation Ruling TR 2018/5, what matters is the substance of where the high-level strategic decisions are genuinely made, not where the company is registered, and not where you hold the board meetings for show. If the controlling mind of the company sits in Australia, your “foreign” company can become an Australian tax resident, taxed here on its worldwide income.

One important distinction, because it’s easy to muddle: this isn’t simply about whether you’re personally an Australian tax resident. If you’re physically offshore but still an Australian resident for your own tax purposes, the company-residency question still turns on where the company’s central management and control is actually exercised, not on your personal status. You might still have CFC, personal-tax or attribution issues (more on those below), but don’t collapse them into the company-residency test. Different trap, same paddock.

And flying directors overseas to rubber-stamp decisions already made in Australia doesn’t fix it. The ATO’s compliance approach in PCG 2018/9 is focused on substance, not theatre. It has seen board-minute cosplay before.

There’s a reform footnote worth knowing. Earlier corporate-residency reform proposals would have moved toward a “significant economic connection” test for foreign-incorporated companies, requiring both core commercial activities and central management and control in Australia. As at June 2026 that proposal has not become the operative law, so plan around the law we actually have, not the reform people have been waiting for. Tax planning by wish list rarely ends well.

Even if the company is genuinely foreign, Australia may still tax some of its profits

Suppose you get the structure right and your foreign company really is a foreign resident, run and controlled offshore. Good, sensible, and still not the end of the Australian story, because Australia has anti-deferral rules designed to stop residents parking income in offshore companies and indefinitely delaying Australian tax.

The main one is the controlled foreign company (CFC) regime. Broadly, if you’re an Australian resident with a substantial interest in a foreign company, some of its income can be attributed to you and taxed in Australia before a dividend is ever paid. The important word is “some”: active business profits are generally treated differently from passive income, related-party income and other tainted income, and the active income test, the country involved, the ownership structure and the type of income all matter. In plain English, a genuine trading business isn’t automatically a tax disaster; a foreign company stuffed with passive income, related-party receipts or Australian-connected dealings is where the alarm bells start charging rent.

Foreign trusts are their own swamp. The transferor trust rules can attribute income where an Australian resident has transferred value to a non-resident trust, and separately, section 99B can tax Australian residents on certain payments or benefits received from foreign trusts. If someone suggests holding the business through a foreign trust because “that’s what everyone does offshore,” pause. Offshore folklore isn’t legislation.

Bringing the money home, and not being taxed twice

When the overseas business eventually pays you, whether as salary, dividends, interest, royalties, trust distributions or something else, the character of the payment matters, and if you’re an Australian tax resident, that income generally needs to be considered for your Australian return.

The foreign income tax offset (FITO) can help where eligible foreign tax has been paid on income that’s also assessable in Australia. But don’t overread it. Foreign corporate tax paid by the company isn’t automatically your personal tax credit; dividend withholding tax, salary tax, and tax paid by the right taxpayer on the right income can be quite different stories. Same money trail, different tax buckets. The offset is also limited: if it exceeds the Australian limit on that income, the excess isn’t refunded and can’t be carried forward. So it relieves genuine double taxation, but it doesn’t guarantee a perfect one-for-one wash.

The relevant tax treaty matters here too. Under the business-profits article of many Australian treaties, one country can tax the business profits of an enterprise from the other country only where the enterprise has a “permanent establishment” there, and generally only to the extent the profits are attributable to that permanent establishment. That sounds neat until you apply it to real life: premises, staff, dependent agents, management activity, contracts, servers and warehouses can all bear on whether a permanent establishment exists and where the business is really carried on. A treaty is useful, but it isn’t a travel adapter you plug in and forget.

The other bits and pieces

A few more Australian-side matters tend to come up when you own a business abroad. Foreign currency gains and losses can have their own tax treatment under Australia’s forex rules, so exchange-rate movements on your overseas dealings aren’t always tax-neutral.

GST is another one to check rather than guess. If the overseas business makes sales connected with Australia (including some imported services, digital products or low-value goods supplied to Australian consumers), Australian GST registration can be required once the relevant GST turnover reaches $75,000. A foreign company, a foreign website and a foreign bank account don’t automatically keep Australian GST away; the GST system has internet access now.

Selling later? The CGT rules are moving under your feet

If you later sell the overseas business, or the shares in the entity that owns it, Australian CGT can still matter depending on your residency, your structure, and whether Australia has kept the asset in its tax net.

There’s also a timing issue worth flagging: the 2026-27 Federal Budget proposed replacing the 50% CGT discount with inflation-based indexation and introducing a minimum 30% tax rate on capital gains from 1 July 2027. Bills have been introduced, but this isn’t yet law and the final detail should be checked before relying on it. For a business sale, that’s not background noise, it’s the drumbeat. If the exit is part of the plan, model it before you buy, rather than collecting future surprises. We track the changes in our 2026 Budget guide for expats.

One firm warning on “structuring”

You’ll find no shortage of people online promising clever offshore structures that make Australian tax disappear. Be careful, sometimes violently careful, because there’s a real difference between genuine commercial structuring and artificial tax theatre.

Genuine commercial structuring means the business is actually run where it says it’s run, has real people and functions, prices its related-party dealings properly, and produces a tax result that matches commercial reality. Artificial structuring means nominee directors, board meetings for show, offshore trusts nobody quite understands, and arrangements whose main job is to make Australian tax look smaller. Australia has a whole toolkit for the second kind: the company-residency test deals with where a company is really controlled; the CFC and transferor trust rules can bring certain offshore income back into the Australian net before any cash is paid out; transfer pricing rules require international related-party dealings to be at arm’s length; and the general anti-avoidance rule (Part IVA) can attack schemes with a dominant tax-avoidance purpose. Add automatic exchange of financial information between tax authorities, and “nobody will find it” stops being a strategy and becomes a confession with poor timing.

Nothing in this article is a recommendation to enter any particular structure. The right one depends on the business, the country, the owners, the treaty, the timing and the exit plan, and anyone selling you a universal offshore answer is probably selling the invoice harder than the advice.

The bottom line

Buying a business overseas can be a brilliant move, and the lifestyle and commercial reasons for doing it are real. But do the tax homework with the same seriousness you’d give the due diligence on the business itself.

Work out your Australian residency first. Then map the exit tax, company residency, the CFC and foreign trust rules, the treaty position, FITO treatment, GST exposure, foreign currency issues and the eventual sale. The right answer depends on whether you buy assets or shares, hold personally or through an entity, run the business locally or from Australia, and whether you plan to come home. A bit of money spent on advice up front is almost always trivial next to the cost of unwinding a structure that looked clever in a pitch deck and feral in a tax audit.

And if you happen to be looking at this from the other direction, moving to Australia to start or buy a business here, the issues flip around, and we cover those in our guide on moving to Australia to start a business.
