For an Australian who owns an international or online business and is genuinely willing to relocate, the Cayman Islands offers the cleanest tax position of any destination in this series: no income tax, no corporate tax, no capital gains tax and no inheritance tax. Like our Greece, Italy, UAE and Singapore strategies, it depends on genuinely moving there. But Cayman differs from the UAE and Singapore in one important respect, and it is the first thing to be honest about: there is no cheap, free-zone-style route where you incorporate a small company and sponsor your own visa. Cayman's residency routes are built around investment and genuine business substance, with meaningful financial thresholds.
This guide sets out how the strategy works, who it works for, how the tax position arises, the residency routes available, how an Australian becomes genuinely resident, and the issues that have to be managed to make it hold up.
The strategy in one paragraph
An Australian relocates to the Cayman Islands and obtains residency through one of its business or investment routes: a Certificate of Direct Investment, granted to a person who invests around US$1.2 million in a licensed, employment-generating Cayman business that the person then works in; or a Residency Certificate for Substantial Business Presence, granted to a person who holds at least a 10 per cent interest in, or a senior management role in, an approved category of business such as a Cayman exempted company. A Residency Certificate for Persons of Independent Means, and a lighter remote-worker programme, are alternatives. With residency granted, the person genuinely moves to Cayman and, because Cayman levies no income, corporate, capital gains or inheritance tax, pays no Cayman tax on any income or gains at all.
Who the strategy works for
Because the entry thresholds are high, Cayman suits a narrower group than the other destinations. It works for people who have substantial capital to invest, who run an established international business or a financial-services-type business that fits the approved categories, and whose wealth sits largely in investments and gains that Cayman will not tax. It is particularly powerful for someone whose return comes from capital gains, because Cayman has no capital gains tax of any kind.
As with the other strategies, the income has to be genuinely international or location-independent rather than tied to an Australian premises or customer base, and the owner has to be willing to actually live on a small Caribbean island. For those who cannot meet the investment thresholds but want a foothold, the remote-worker programme is a lighter, temporary alternative.
How Cayman taxes you
It does not. The Cayman Islands has no income tax, no corporate tax, no capital gains tax, no inheritance or estate tax, and no general sales or value-added tax. Government revenue is raised through import duties, work-permit and licensing fees, and stamp duty on property. For a Cayman resident, salary, business profits, dividends, interest, rent and capital gains are all received free of any Cayman tax.
Set against Australian marginal rates of up to 47 per cent on worldwide income, including capital gains, the Cayman position is the most favourable in this series, because there is simply no local tax on the income side at all. The trade-off is the cost of entry and the cost of living, not local tax.
The residency routes: investment and substance, not a token company
Residency in Cayman is obtained by investing or by demonstrating a genuine business presence, not by incorporating a small company and sponsoring yourself. The main routes are:
- Certificate of Direct Investment. Granted to a person who invests, directly, around US$1.2 million in a licensed business in Cayman that employs Caymanians, and who is employed in a senior role in that business. The certificate allows the holder to live in Cayman and work in the business invested in. It is a long-term certificate, generally valid for 25 years and renewable, and carries a minimum annual physical-presence requirement.
- Residency Certificate for Substantial Business Presence. Granted to a person who owns at least a 10 per cent interest in, or holds a senior management position in, an approved category of business. The approved categories are financial-services focused, including fund administration and management, investment and brokerage services, insurance and reinsurance, family office, and companies registered as exempted companies under the Companies Act. This is the route closest to "set up or run a company and be employed by it", but the business must genuinely fall within an approved category and have a real operating presence in Cayman, which in practice means commercial premises and the employment of at least four people resident in the Islands.
- Residency Certificate for Persons of Independent Means. Granted to a person who invests in Cayman, typically around US$1.2 million including developed real estate, and who can demonstrate a substantial and continuing annual income from outside Cayman. This route does not carry the right to work.
- The remote-worker programme. A lighter, temporary route for a person who works remotely for an employer outside Cayman and earns above a set annual income, allowing residence for a limited period. It is the most accessible entry point, but it is temporary and is tied to foreign employment rather than a Cayman business.
The exact dollar thresholds, fees and category lists are set by Cayman immigration and should be confirmed as current before any application, but the shape is consistent: real investment or genuine, approved business substance, not a nominal company.
The corporate side
A Cayman exempted company pays no Cayman tax, which is the ordinary vehicle for an international business based there. Cayman does, however, have economic-substance rules under its International Tax Co-operation (Economic Substance) Act, which require entities carrying on certain relevant activities to demonstrate adequate substance, people and expenditure in Cayman. A company used in the structure has to be set up with those requirements in mind, and the substantial-business-presence residency route in particular assumes a genuine operating presence rather than a shelf company.
Becoming genuinely resident
Cayman has no income tax and therefore no concept of tax residency in the sense the other destinations use. What matters for this strategy is immigration residency combined with genuinely living there. The investment and business-presence certificates carry a minimum annual physical-presence requirement, but for the purpose of ceasing Australian tax residency the move has to be real, not a paper presence. For an Australian who genuinely relocates to Cayman and makes it their home, the absence of Australian tax on their offshore income and gains follows from their no longer being an Australian tax resident, and (eventually) being settled in a jurisdiction that imposes no tax of its own.
The issues that have to be managed
The tax outcome is the strongest in this series, but it depends on four things being handled properly.
1. Ceasing Australian tax residency
The Cayman position only helps once the owner is no longer an Australian tax resident. While they remain an Australian resident, Australia taxes their worldwide income and capital gains at rates up to 47 per cent. The departure must be deliberate and well evidenced, and it must account for CGT event I1, which deems a disposal of the departing resident's non-Australian-property assets at market value on the day they cease to be a resident. Australia does not have a comprehensive double tax treaty with the Cayman Islands; there is an information-exchange arrangement, but no treaty tie-breaker to resolve a dual-residence year. A move to a zero-tax jurisdiction with no treaty draws the closest scrutiny from the Australian Taxation Office on whether residency has genuinely ended, so the relocation has to be real and capable of proof.
2. The cost and threshold reality
Cayman is not a low-cost relocation. The investment routes require around US$1.2 million, and the substantial-business-presence route requires a genuine approved-category business, not a shelf company. The remote-worker programme is the only light-touch entry, and it is temporary. The cost of living is also high. The strategy only makes sense for someone with the capital to meet the thresholds comfortably.
3. Substance: the business and the person must genuinely be there
If the business is in substance still run from Australia, Australia can treat the company as an Australian tax resident on the basis that its central management and control is in Australia. Cayman's own economic-substance rules pull in the same direction, expecting genuine activity in Cayman. Real management and operation from Cayman, consistent with the owner having actually relocated, is essential to both.
4. What is taxed, and where
Cayman taxes nothing, which means the only tax questions that remain are the Australian exit and the rules of any other country that touches the income (for example, withholding tax in the country where income is sourced). The structure should be built with a clear view of those, because Cayman's zero-tax status does not switch off other jurisdictions' taxing rights.
Is the Cayman Islands the right destination?
Cayman suits high-net-worth individuals with substantial investment wealth and the capital to meet the investment thresholds, who run an international or approved-category business, and who will genuinely relocate to a small and expensive island. It offers the strongest tax outcome in this series, no tax at all on income or gains, but it carries the highest entry cost and, because there is no treaty with Australia, the closest scrutiny of whether the Australian exit is genuine. It is less suited to those who cannot meet the thresholds, or who will not actually relocate.
For the right person the combination is unmatched: no income tax, no capital gains tax, no inheritance tax, and a stable, well-regulated financial centre. The strategy rewards being deliberate. The relocation has to be real, the residency route has to be properly funded and structured, and the Australian exit has to be clean.
