Australia vs UAE taxes

Australia and the UAE are not close on personal tax. Australia is a full residence-based system: residents generally report worldwide income, pay progressive rates up to 45%, and usually add a 2% Medicare levy. Capital gains sit inside that same income-tax system, even when individuals get a 50% discount after holding an asset for more than 12 months. Companies pay 25% if they qualify as base-rate entities or 30% under the general rate, and GST is 10%. There is no general net wealth tax and no federal inheritance tax, but stamp duty, land tax and superannuation death-benefit rules can still create transfer costs.

The UAE still has no personal income tax, no general personal capital gains tax, no wealth tax and no inheritance tax. Federal corporate tax is 0% up to AED 375,000 of taxable income and 9% above that threshold, with a separate 15% domestic minimum top-up for in-scope large groups. VAT is 5%. That is a simpler and lighter stack for a mobile earner, provided the person actually lives and works under a UAE residence visa and the business can show real management in the Emirates.

The constraint that decides most moves is not the 9% company rate. It is how you become, or stop being, a tax resident. Australia looks at presence, including a 183-day test, plus other residential ties. Crossing that line usually means worldwide tax and Medicare. The UAE does not levy personal income tax, but a visa, licensing and substance still control whether the Gulf base is real. Australian-source salary, property or company income can remain in Australia's net even after you fly out.

Choose the UAE when the income is portable and you can document residence and management there. Choose Australia when the commercial or family reason for being in Australia is stronger than the tax saving. Treaties, CFC rules and Division 7A can still pull Australian-connected structures back into the Australian system, so a company in Dubai does not, by itself, rewrite an Australian founder's position.
