Moving from Australia to Greece can drop a high-earning founder or family-office principal from a 47% top marginal rate to a hard cap of €100,000 a year on worldwide income for fifteen years — under Greek Article 5A non-dom rules — with EU residency and an EU passport pathway thrown in. The two costs that dominate the planning are Australia’s CGT event I1 (the unrealised-gains “deemed disposal” the ATO triggers the day you cease residency) and the €500,000 qualifying Greek investment that Article 5A demands within three years of acceptance. Get the sequencing wrong and you can either pay the Greek flat tax and the Australian capital-gains bill in the same calendar year, or fall into the gap between regimes and end up taxed twice on the same income.
The Tax Delta at a Glance
| Australia (current) | Greece (after move, Article 5A non-dom) | |
|---|---|---|
| Personal income tax | 0–45% + 2% Medicare = up to 47% | €100,000 flat per year on all foreign income |
| Capital gains tax | Taxed as income (50% discount if held >12 months) | Foreign CGT absorbed in the €100K flat; 15% on Greek non-listed shares |
| Dividend tax | Franked: imputation; unfranked: marginal rate | €0 extra on foreign dividends; 5% on Greek dividends |
| Wealth / inheritance | No wealth tax; CGT applies on inherited assets to non-residents | No wealth tax; 1–10% inheritance to spouse/children (€150K threshold) |
| Worldwide vs territorial | Worldwide for residents; source-based for non-residents | Worldwide, but flat-tax cap on the foreign portion |
| Effective rate (founder taking AUD 1.5M of foreign dividends) | ~47% (~AUD 705K) | ~10% (€100K ≈ AUD 165K) |
Step-by-Step Move
Step 1: Confirm you can legally cease Australian tax residency
The ATO does not apply a single bright-line day-count test. Four overlapping tests run in parallel and you remain a tax resident if you satisfy any one of them: the Resides Test (the common-law “do you reside here in the ordinary sense?” question), the Domicile Test (you remain resident if your domicile is in Australia unless the Commissioner is satisfied your permanent place of abode is overseas), the 183-Day Test, and the Commonwealth Superannuation Test. The most-litigated is the Domicile Test. The leading authority — Harding v FCT [2019] FCAFC 29 — confirmed that a “permanent place of abode” overseas does not require a single forever-home, but it does require that you have abandoned Australia as your home in a real, durable sense. Short-term Athens rentals while a Sydney house sits empty, a spouse and school-age children left in Australia, or an Australian-employer payroll all weigh heavily against you.
You are aiming to satisfy the ATO that on a specific departure date you ceased to reside in Australia and ceased to have your domicile of choice there. From that date you are assessable only on Australian-source income and on disposals of Taxable Australian Property (essentially direct or indirect interests in Australian real estate). Until that date you remain assessable on worldwide income — including, importantly, any Greek-source income you earn during the run-up.
Step 2: Plan around Australia’s exit tax — CGT event I1
This is the single biggest line item in any Australia-to-Greece exit. Under section 104-160 of the Income Tax Assessment Act 1997, the moment you cease to be an Australian tax resident, CGT event I1 is triggered on every CGT asset you own that is not Taxable Australian Property. The ATO treats those assets — listed Australian shares, foreign equities, ETFs, private company shares, ESOP holdings, crypto (TD 2014/26 confirms crypto is a CGT asset), and most fund interests — as disposed of at market value on the departure date. The capital gain is assessed in your final Australian part-year return.
Individuals (but not companies) may make an irrevocable election under s104-165(2) to disregard the gain on departure — the so-called “I1 election.” If you elect, no Australian tax is payable on departure, but every elected asset is deemed to remain Taxable Australian Property in your hands until you actually dispose of it. The ATO retains taxing rights over the eventual sale even after you become a Greek tax resident; the gain on actual disposal is fully assessable in Australia at non-resident rates with no 50% CGT discount for the post-8 May 2012 portion and no tax-free threshold.
For someone heading to Greek Article 5A this is a particularly sharp decision, because the €100K Greek flat tax already covers the eventual foreign capital gain. If you take the Australian I1 election to defer, Australia keeps full taxing rights over the gain on actual sale; Greece collects nothing extra (the gain is inside the €100K). You end up paying Australian non-resident rates on a sale Greece would have absorbed for free. The right answer for most founders is therefore the opposite of the deferral default — trigger CGT event I1 on departure, pay the Australian tax once with the 50% CGT discount intact for assets held over 12 months, and hand Greece a clean, stepped-up cost base. Run both calculations before booking the flight: the choice between paying ~23.5% effective now versus 45% non-resident rates on a future sale is often the largest single decision in the move.
Step 3: Establish Greek tax residency and file Article 5A
Greek tax residency follows the standard test: 183+ days in Greece in any 12-month period, or centre-of-vital-interests in Greece. Most successful Article 5A applicants spend 183+ days on the ground both to satisfy Greece and to break Australian residency cleanly.
The Article 5A non-dom regime under Law 4646/2019 is the headline reason to choose Greece. Mechanics:
- You must not have been a Greek tax resident for at least 7 of the previous 8 tax years — every Australian arriving for the first time clears this easily.
- You must commit to a qualifying investment of at least €500,000 in Greek real estate, Greek companies, Greek securities or AIFs, completed within three years of acceptance. Golden Visa property investments count toward the €500K, so the two regimes stack.
- Application deadline: 31 March of the tax year you want to be taxed under Article 5A. Miss the date and you wait a full year.
- Annual cost: €100,000 flat on all foreign income, paid in a single instalment by 31 July, plus €20,000 per qualifying family member added.
- Duration: up to 15 tax years, non-renewable.
Full destination-side detail is on the Tax-Free Residency in Greece page. Australians who don’t need flat-tax treatment can alternatively use the Golden Visa (€250K–€800K real estate depending on region, with no minimum stay) or the Financially Independent Person visa (~€3,500/month verified income), both of which let you live in Greece without triggering Greek tax residency unless you also hit the 183-day or centre-of-vital-interests tests.
Step 4: Document the break and the new tie
Australian audit defence is a documentation exercise. Build a contemporaneous file: signed Greek lease or purchase contract dated before departure, biometric residence card / Article 5A acceptance letter, Greek AFM (tax number) certificate, Greek utility bills in your name, Greek bank statements, Greek private health insurance, Australian principal residence sold or genuinely let at arm’s length (written tenancy agreement and rental ledger), Australian Medicare card cancelled, electoral roll removed, Australian driver’s licence surrendered or marked as overseas, and — most importantly — a Greek tax residency certificate issued by AADE for the first full Greek year.
The Australia–Greece Double Tax Convention, signed in Athens on 18 October 2023, is the first comprehensive treaty between the two countries and applies to income years beginning on or after the calendar year following entry into force in both states. It contains a standard OECD-model tie-breaker in Article 4: permanent home → centre of vital interests → habitual abode → nationality. Confirm current treaty status on the ATO’s tax-treaties page before lodging — for any year the treaty is not yet in force, your only protection is Australian domestic residency rules and the documentary record above.
Step 5: First-year compliance in both jurisdictions
Australia: lodge a part-year resident return for the income year ending 30 June covering 1 July to your departure date, with the CGT event I1 schedule (or the s104-165 election) attached. Continue to lodge a non-resident return in any year you have Australian-source income — rent on a retained property, Australian dividends (subject to non-resident withholding), or a disposal of Taxable Australian Property. Non-residents lose the tax-free threshold and pay 32.5% from the first dollar of Australian-source income.
Greece: if you’ve been accepted into Article 5A, pay the €100,000 flat by 31 July of each year and lodge an annual personal income-tax return declaring your Greek-source income (any income earned inside Greece sits outside the flat tax and is taxed at standard progressive rates). Register with AADE for an AFM, set up TaxisNet credentials, and budget for ENFIA (the annual Greek real-estate tax) on any qualifying-investment property.
Cost & Timeline
| Phase | Cost (AUD) | Time |
|---|---|---|
| Pre-departure tax planning + I1 modelling | $5,000–$15,000 | 1–3 months |
| CGT event I1 / part-year return (Australian agent) | $3,000–$10,000 | 1–3 months after EOFY |
| €500K Greek qualifying investment | ~AUD 800K+ | Up to 3 years post-acceptance |
| Article 5A filing (Greek tax counsel) | $12,000–$30,000 | 60-day approval window |
| Golden Visa / residence permit | $8,000–$15,000 + government fees | 2–6 months |
| Move + relocation logistics | $15,000–$60,000+ | 1–2 months |
| First-year dual filing (AU final + GR first) | $7,000–$15,000 | Annual |
| Total year-1 effective cost | AUD 50,000–$140,000 + €100K flat + I1 tax | 6–12 months |
The dominant variables are the I1 tax bill itself and the €500K investment. A founder sitting on AUD 5M of unrealised gains on listed equities held more than a year faces roughly AUD 5M × 50% discount × 47% ≈ AUD 1.18M of Australian tax at departure. The €500K Greek investment is recoverable capital (you keep the asset), but it must be in qualifying Greek instruments and held for the duration of the regime.
Treaty Considerations
The Australia–Greece DTC, signed 18 October 2023, follows the OECD Model. Once in force in both countries it does three useful things for Australian-Greek relocations:
- Tie-breaker for dual residency. Article 4 resolves cases where Australian and Greek domestic rules both claim you in the order permanent home → centre of vital interests → habitual abode → nationality. For a clean Athens-based founder with no Australian home, family or business, Greece will win the tie-breaker on the first test.
- Reduced withholding on Australian-source dividends and interest paid to Greek tax residents — typically capped at 15% on dividends (lower for substantial holdings) and 10% on interest, against Australia’s standard 30% non-resident rate on unfranked dividends.
- Credit relief, eliminating juridical double taxation on income that remains taxable in Australia after departure (rent on retained property, ESS interests, Taxable Australian Property gains).
Critically, the Greek €100,000 flat tax is not a tax exemption — it is an alternative tax paid in Greece on foreign income. AADE issues a Greek tax residency certificate to Article 5A residents, and most jurisdictions (including Australia under the new treaty) accept it. For Greek-source income there is no overlap to manage; for Australian-source income, the treaty’s credit mechanism applies in the normal way.
Common Mistakes
- Leaving without breaking the Resides/Domicile Test cleanly. Keeping a Sydney family home “available” while you trial-live in Athens is the classic failure mode — the ATO will argue you never ceased to reside, and Harding won’t save you.
- Taking the I1 deferral election by default. It is almost always wrong for someone heading into Article 5A: Greece would have absorbed the gain inside the €100K flat anyway, so deferral converts a 0% Greek event into a 45% future Australian event.
- Missing the 31 March Article 5A filing window. If you depart Australia in May 2026 expecting to start Greek non-dom in 2026, the deadline has already passed — you’ll be a normal Greek tax resident on progressive 9–44% rates for an entire year before Article 5A kicks in.
- Not pre-funding the €500K investment. The investment can be made within three years of acceptance, but most successful applicants close on Greek real estate or the AIF subscription before filing so that the investment evidence is part of the application file.
- Keeping a permanent home or family in Australia. Once the Australia–Greece DTC is in force, the tie-breaker’s centre-of-vital-interests test will land you back in the Australian net if your spouse and minor children remain in Sydney — regardless of where you sleep.
FAQ
Will I still have to file in Australia after moving?
Yes, in two situations: the part-year return for the year of departure (covering 1 July to your departure date with the CGT event I1 schedule), and any later year you have Australian-source income — typically rent on a retained Australian property, distributions from an Australian trust, dividends from Australian shares (subject to non-resident withholding), or a disposal of Taxable Australian Property. Australia does not impose citizenship-based taxation, so once your Australian-source income stops, your Australian filing obligations stop too.
Can I keep my Australian bank account, super and property?
Yes to all three. Banks reclassify the account as non-resident (10% withholding on interest paid to non-residents). Your superannuation keeps its concessional treatment while preserved, but you cannot make most contributions as a non-resident; pension-phase withdrawals after 60 are tax-free in Australia and absorbed by the €100K Greek flat (so effectively tax-free in Greece too). Australian real estate triggers non-resident CGT on sale — no 50% discount on the post-2012 portion and no main-residence exemption for the post-departure period since the 2019 reforms.
How does the €100K flat tax interact with my franked Australian dividends?
Franking credits are only refundable to Australian tax residents. After moving, unfranked Australian dividends suffer 30% non-resident withholding (reduced to 15% under the new DTC); franked dividends are fully franked and effectively pay no further Australian withholding. Either way, the dividend is then absorbed in your €100K Greek flat — Greece does not double-tax it. Many Australian founders restructure into non-Australian holding companies before departure to escape the 30% withholding altogether.
What happens after the Article 5A 15 years are up?
The regime is non-renewable. From year 16 onward you face standard Greek progressive rates (up to 44%) on worldwide income unless you exit Greek tax residency. Many Australian families plan an exit before year 15 — typically into Cyprus 60-day non-dom residency or back to a low-tax jurisdiction — and treat the 15-year window as a finite planning horizon.
Does the Greek Golden Visa make me a Greek tax resident?
No. The Golden Visa is purely an immigration status — it gives you the right to live in Greece and travel Schengen, but you only become tax resident when you actually meet the 183-day or centre-of-vital-interests tests. Many Golden Visa holders never become Greek tax resident and continue to file as Australian residents (or in a third country).
What if the ATO disputes my exit?
ATO disputes typically focus on the Domicile Test and on contemporaneous evidence. The defence is paper: sold or arm’s-length-let Australian home, spouse and dependants relocated, Greek tax residency certificate for the first full year, signed Greek lease pre-dating departure, Australian Medicare and electoral roll cancelled, and a clean part-year return with CGT event I1 properly disclosed. With that record and the Article 5A acceptance letter from AADE, post-Harding case law strongly favours the taxpayer; without it, the ATO will press the point under the four-year amendment window.
