A business worth AUD 4M, built from nothing, generates about AUD 940,000 in Australian tax the moment its founder stops being an Australian resident — even though nothing has actually been sold. That's CGT Event I1.

The CGT Event I1 Problem for Business Owners

When an Australian tax resident ceases residency, CGT Event I1 deems most of their capital assets sold at market value on the day residency ends. For an online business owner, your business shares fall into this. If your SaaS or consultancy has meaningful value, CGT Event I1 crystallises the unrealised gain.

Australia's top marginal rate is 47% (45% plus the 2% Medicare Levy). The 50% CGT discount reduces the effective rate on qualifying gains to around 23.5%. For a business valued at AUD 4M with a nominal cost base, ceasing Australian residency triggers approximately AUD 2M in taxable capital gain after the discount — approximately AUD 940K in tax.

What CGT Event I1 Covers

Included:

• Shares of your Australian operating company

• Foreign shares

• Non-Australian real estate

• Cryptocurrency

• Managed funds

Excluded ("taxable Australian property" — remains subject to Australian CGT whether or not you're resident):

• Australian real estate

• Business assets tied to an Australian permanent establishment

The Opt-Out Election

Australians ceasing residency can elect not to trigger CGT Event I1 on non-taxable-Australian-property assets. Instead, those assets stay subject to Australian CGT until eventually sold, even after emigration.

This is often the better answer for founders moving to destinations without CGT treaty relief with Australia — a gap that, as the next section explains, is wider than the article you might have read elsewhere assumes.

If you elect to opt out:

• No immediate tax on emigration

• Australian CGT continues to apply to those assets whenever they're eventually sold

• Ongoing Australian filing is required on eventual disposal

• You lose the 50% CGT discount on gains accruing after you cease residency

The election is asset-specific — you can make it per asset or in aggregate.

Small Business CGT Concessions Pre-Emigration

If your online business is an active business, not a passive investment, small business CGT concessions can dramatically reduce or eliminate the CGT bill.

Four main concessions:

• 15-year exemption (age 55+, genuinely retiring)

• 50% active asset reduction, on top of the general 50% discount

• Retirement exemption, up to AUD 500,000

• Small business rollover

None of these is capped by the value of the business itself. Eligibility instead runs through the ATO's basic conditions: a AUD 6 million net-asset-value test, or a AUD 2 million aggregated-turnover test, plus a few other conditions depending on the concession used. That distinction matters specifically for online founders — an asset-light SaaS or content business can be worth well over AUD 3M while carrying modest net assets, and still qualify. Don't rule yourself out because your business is "worth too much," and don't assume you qualify just because your valuation looks low — check the actual net-asset and turnover tests against your business, not its headline price tag.

Using these concessions before emigration is often the highest-value planning move available to you.

Superannuation on Departure

Super generally stays put wherever you go. Withdrawals from super in the pension phase (age 60+) are Australian tax-free.

Destination country treatment varies. Colombia, Panama, and other no-treaty countries may tax super drawdowns depending on how they're characterised locally; the UAE (zero tax), Portugal (post-NHR, now IFICI, at ordinary rates), and treaty countries each have their own approach.

SMSF founders need particular care: the "central management and control" test can jeopardise an SMSF's Australian tax status if all trustees become non-Australian-resident.

The No-Treaty Problem for Australians

Australia has no tax treaty with Colombia, Panama, or the UAE — despite the UAE being the single most popular destination among Australian founders in this series.

Without a treaty:

• No formal residence tie-breaker

• No reduced withholding rates on cross-border income

• No formal double-tax relief mechanism

Australia does have treaties with the US, the UK, Canada, most EU countries, Singapore, and roughly 47 partner jurisdictions in total. The UAE is not one of them, and no timeline for a treaty has been publicly announced as of September 2026.

That changes the UAE's actual risk profile for an Australian founder. Zero personal tax there is real. But without a treaty, there's no formal mechanism to prevent double taxation, and no tie-breaker to resolve a residency dispute if the ATO and the UAE authorities ever disagree about where you're genuinely resident — the same structural gap Panama and Colombia already carry. Treaty coverage matters more for Australian founders choosing a destination than it typically does for other nationalities in this series, and the UAE, despite its reputation, sits on the wrong side of it.

Where Australian Online Business Owners Are Relocating

• UAE
  Treaty with Australia: No
  Note: Zero personal tax remains the draw, but no treaty means no formal double-tax relief mechanism — see above

• Singapore
  Treaty with Australia: Yes
  Note: Treaty coverage plus a sophisticated business ecosystem

• USA (particularly Puerto Rico, Act 60)
  Treaty with Australia: Yes
  Note: Treaty coverage plus Act 60's specific benefits

• Bali/Indonesia
  Treaty with Australia: Yes
  Note: Lifestyle draw plus the Second-Home Visa; tax outcomes vary

• Portugal (D7/D8)
  Treaty with Australia: Yes
  Note: Treaty coverage plus lifestyle, though NHR has closed to new entrants in favour of the narrower IFICI regime

• UK
  Treaty with Australia: Yes
  Note: Treaty coverage plus family and language ties; less tax-attractive post-non-dom-reform

• Panama
  Treaty with Australia: No
  Note: Despite no treaty, USD structuring and lifestyle draw Australian founders; requires careful characterisation planning

The Practical Sequence

24 months before: value the business realistically, model your CGT Event I1 exposure, check small business CGT concession eligibility against the actual net-asset and turnover tests, and weigh destination-country treaty coverage.

12 months before: choose your destination country and establish preliminary infrastructure; plan business restructuring if it's beneficial.

6 months before: formalise destination residency, decide on the opt-out election, and reduce Australian ties.

Departure year: file your final Australian return covering the pre-departure period, make CGT Event I1 elections as appropriate, and establish clear tax residency in your destination.

What to Model Before You Leave

If you're an Australian founder planning to emigrate, book a scoping call. We'll run your CGT Event I1 exposure against small business concession eligibility and your destination country's actual treaty position — UAE included — before you set a departure date.
