Australia taxes you on a deemed disposal of everything you own outside superannuation the day you stop being a resident. Panama's territorial system won't rescue you from that first bill — it only decides what happens to your money once you're already through the door.

The Exit Bill: CGT Event I1

The day you stop being an Australian tax resident, the ATO treats you as though you'd sold most of what you own outside superannuation and Australian real property. This is CGT Event I1, sometimes called the departure tax. It doesn't touch your superannuation interests — those aren't CGT assets in your hands, the fund holds them — and it doesn't touch Australian real property or other "taxable Australian property", which stays taxable regardless of where you live afterwards. What it does catch is everything else: an Australian share portfolio, managed funds, foreign shares, deemed disposed of at market value on the date you leave, with the resulting gain taxed in your final resident return.

You do get a choice. Elect to defer CGT Event I1 on a given asset and the ATO treats you as still resident for that asset until you actually sell it — useful if the market's down the day you leave, or if you expect to come back within a few years. Defer, and you also carry the currency risk and the ongoing compliance obligation forward with you. There's no free option here, only a different set of numbers to model before you pick one.

Take Margaret, 63, who holds an Australian share portfolio built up over two decades alongside her superannuation. Leave without electing to defer, and that portfolio is deemed sold the day she becomes a non-resident, with any accrued gain taxed in her final Australian return — a real cash bill, landing in the same year she's paying for the move itself. Elect to defer, and she postpones that bill but stays inside the Australian CGT system for those specific assets until she genuinely sells them, wherever she's living when she does. Which choice is right depends entirely on what's in the portfolio and what she expects to do with it, not on a general rule.

The Residency Tests You Have to Fail on Purpose

Ceasing Australian residency isn't a single test — it's four, and you need to fail all of them to be genuinely non-resident. The primary test is the "resides" test: the ordinary meaning of where you live, judged on your actual behaviour, not a form you filled in. Behind it sit three statutory tests. The domicile test asks whether you still have an Australian domicile and, if so, whether the Commissioner accepts you've set up a permanent home elsewhere. The 183-day test asks whether you were in Australia more than half the income year. The superannuation test catches contributing members of a Commonwealth super scheme, which mostly means Australian government employees. Meet any one of these and you can still be treated as a resident, even while you're sitting in a Boquete café telling yourself you've left.

Superannuation Once You're a Non-Resident

Superannuation itself behaves better than most retirees expect. If you're over preservation age and drawing from a taxed super fund — the large majority of Australian funds are — your pension or lump sum withdrawals are tax-free in Australia whether you're a resident or not, because the tax was already paid inside the fund. Panama's territorial system doesn't touch it either, since it's foreign-sourced income received outside Panama's tax net. Where non-residency actually bites is around the income and gains you generate outside super after you've left, and around franking credits.

Franking Credits Stop Working the Way You're Used To

Franking credits attached to Australian share dividends assume you're a resident filing an Australian return that can use them — either against tax payable or, for many resident retirees on a low income, refunded in cash if you owe no tax that year. Once you're a non-resident, that straightforward cash-refund path isn't available to you the way it was. If franked dividends are a meaningful slice of your retirement income, this is worth modelling before you leave, not after you've filed your first return as a non-resident and noticed the number is smaller than expected.

No Treaty, and What That Actually Means

Panama and Australia have no tax treaty — and despite what some retirement content still claims, none has ever existed. That matters less than it would with a country that taxes worldwide income, because Panama's system is territorial: it only taxes income earned inside Panama, so your Australian superannuation, dividends and offshore investment income sit outside Panama's tax net regardless of a treaty. What you lose without one is the safety net — no tie-breaker residency clause if Panama and Australia ever both claimed you, no treaty-based relief mechanism, no formal dispute-resolution process to fall back on. In practice this rarely bites a retiree living cleanly on superannuation and Australian-sourced investments, but it's a layer of protection other jurisdictions in this series have and Panama doesn't.

Panama's Side: Pensionado and Territorial Tax

Panama's Pensionado visa is built for exactly this move. You need a guaranteed lifetime pension — Australian superannuation qualifies — of at least USD 1,000 a month, or USD 750 a month if you also own Panamanian real estate worth more than USD 100,000. There's no minimum-stay requirement to keep the visa active, which suits retirees who want to split time between Australia and Panama in the early years rather than relocate all at once. Once approved, Pensionado status comes with statutory discounts worth having on a fixed income: 25% off domestic and international airfares, 50% off entertainment, and 15–20% off private medical care and medicines among them.

Getting the Exit Order Right

Book a scoping call before you set a departure date. We'll model CGT Event I1 against your actual portfolio, including whether deferring makes sense for you, check your position against all four ATO residency tests, and map what happens to your franking credits and Pensionado eligibility together rather than as three separate problems solved in the wrong order.

This is general guidance for Australians considering Panama, not a substitute for advice from a registered tax agent who knows your specific superannuation and residency position.
