For an Australian founder post-exit or a senior professional with substantial liquid wealth, moving from Australia to Monaco compresses a top marginal personal rate of 47% (45% income tax plus 2% Medicare levy) to a true 0% on personal income, capital gains, dividends, interest and net wealth — in a stable AAA-rated European jurisdiction with full Schengen mobility. The two binding constraints are uniquely Monégasque: a €1–2 million all-in setup (bank deposit plus housing) and the requirement that you are not a French national post-1962. Layered on top is the Australian-side gotcha that bites every emigrating Australian regardless of destination — CGT Event I1 under section 104-160 ITAA 1997 deems a disposal of every non-Australian CGT asset on the day you cease residency — and the absence of any comprehensive Australia-Monaco double tax agreement, meaning there is no Article 4 tie-breaker if the ATO contests your departure.
The Tax Delta at a Glance
| Australia (current) | Monaco (after move) | |
|---|---|---|
| Personal income tax | 0–45% progressive + 2% Medicare levy (top marginal 47%) + up to 1.5% Medicare levy surcharge | 0% (non-French residents) |
| Capital gains tax | Taxed at marginal rate; 50% CGT discount on assets held >12 months; discount denied to non-residents on Taxable Australian Property gains accrued post-8 May 2012 | 0% on private investment gains (incl. crypto for individuals) |
| Dividend tax | Marginal rate; franking credits offset Australian-company dividends; 30% non-resident withholding on unfranked dividends post-departure (no AU-MC treaty reduction) | 0% on personal dividend income |
| Wealth / inheritance | No estate tax, but CGT on death is deferred, not forgiven for non-resident beneficiaries | 0% annual wealth tax; 0% inheritance between spouses and direct lineal descendants |
| Worldwide vs territorial | Worldwide for residents; CGT Event I1 deemed disposal on cessation | Effectively 0% for non-French resident individuals — no personal income tax base at all |
| Effective rate (NSW founder, AUD $1M mixed income) | ~44–47% | ~0% |
For a Melbourne or Sydney founder anticipating an AUD $20M trade sale, the difference between paying Australian CGT (effective ~23.5% after the 50% discount on long-held shares) and the 0% Monégasque rate on a clean post-residency disposal is on the order of AUD $4.7M — provided the section 104-160 deemed disposal is correctly modelled and elected on at the moment of exit. Annual cash savings on AUD $1M of mixed income hover around AUD $400–450K, which typically pays for the entire Monaco setup advisory layer within the first 12 months even before considering the CGT savings on a major liquidity event.
Step-by-Step Move
Step 1: Confirm you can legally cease Australian tax residency
Australia uses a multi-test residency framework, not a clean day-count rule. Four tests apply, and satisfying any one of them keeps you Australian-resident: (a) the “resides” test — a facts-and-circumstances common-law test of where you ordinarily live; (b) the domicile test — an Australian-domiciled person remains resident unless the Commissioner is satisfied your permanent place of abode is outside Australia; (c) the 183-day test — physical presence for at least 183 days in the income year unless your usual place of abode is overseas and you do not intend to take up residence in Australia; and (d) the Commonwealth superannuation fund test for certain government employees.
The two tests that trip up departing Australians are the domicile test and the resides test. Domicile is “sticky” — the burden is on you to demonstrate a permanent place of abode outside Australia. Taxation Ruling IT 2650 lists the operative factors: intended and actual length of stay overseas, intention to return, establishment of an overseas home, abandonment of any Australian residence, durability of association with the overseas place, and continuing economic, social and family ties in Australia. The Harding v Commissioner of Taxation [2019] FCAFC 29 decision held that a permanent place of abode requires “permanence” in a meaningful sense — a Monaco lease with utility connections, family relocation and a registered carte de séjour clears the threshold; serviced-apartment hopping through European tax-free hubs does not.
A clean Australia-to-Monaco departure typically requires: leasing or selling the Australian principal residence on arm’s-length terms (a furnished house “available for visits” is fatal under IT 2650 / Harding); moving the family unit to Monaco; surrendering Medicare via Department of Human Services notification; cancelling Australian state driver’s licences in favour of a Monégasque permis de conduire; and concluding a registered ≥12-month Monaco lease that generates Monégasque utility bills (electricity, water, telecoms) in your name. Without these tangible steps, the ATO has the evidence — and, as detailed in Step 4, no treaty backstop — to argue you remained Australian-resident.
Step 2: Plan around Australia’s CGT Event I1 deemed disposal
The single largest gotcha is CGT Event I1 under section 104-160 ITAA 1997: at the moment you cease to be an Australian resident, you are treated as having disposed of each CGT asset you own at its market value on the day, with any resulting capital gain or loss assessed in your final-year return. There is no de minimis — every listed share, every cryptocurrency holding, every foreign rental property, every interest in a foreign trust, every private-company shareholding outside the Taxable Australian Property net is in scope.
Taxable Australian Property (TAP) under section 855-15 is excluded from CGT Event I1 — primarily direct interests in Australian real property; indirect Australian real property interests (broadly, ≥10% holdings in entities whose value is principally Australian land); assets used in a business through an Australian permanent establishment; and options or rights over the foregoing. TAP is not deemed-disposed because Australia retains taxing rights over it indefinitely under section 855-10. Crucially, the 50% CGT discount is denied to non-residents on the portion of TAP gains accrued from 8 May 2012 onwards under section 115-115. Obtain a market valuation at the date of departure for any retained TAP and keep it on file for the eventual sale.
For everything else, section 104-165 offers an election to disregard CGT Event I1 for any or all non-TAP assets, in which case the elected assets are deemed to be TAP going forward and remain in the Australian CGT net until actual disposal. The election is made on the final-year return, is all-or-nothing per asset, and is permanent. For Australian founders sitting on long-held private-company shares facing a near-term sale, paying the departure tax in cash with the 50% CGT discount tends to be the cleaner outcome — once Monégasque, the eventual sale is taxed at 0% rather than at Australian non-resident rates without the discount. The election fits niche cases: low-basis growth assets you expect to hold for decades and may dispose of after a possible return to Australia.
Step 3: Establish Monaco tax residency
Monaco residency runs through the carte de séjour issued by the Section des Résidents (Sûreté Publique). The standard “non-active” route requires: non-French nationality (or French nationality settled in Monaco before October 13, 1962); age 16+; clean criminal record from every country of residence in the last five years; a registered Monaco home (owned property or registered lease ≥12 months); and proof of sufficient means, conventionally demonstrated by a deposit of €500,000+ at a Monaco-licensed bank — €1,000,000+ in practice for most HNW applicants. The all-in upfront commitment for a typical Australian family is €1–2 million between the bank deposit, lease deposits or property purchase, and advisory.
The carte de séjour issues in three successive forms — temporaire (1-year, renewable annually for the first three years), ordinaire (3-year, after the initial temporary phase), and privilégié (10-year, after roughly nine years of continuous residency). To be a Monégasque tax resident for the purposes of Australian tie-breaker arguments, you should spend 183+ days/year in Monaco and have your principal home there. Document presence carefully: utility usage, bank-card activity, club memberships and school enrolments are exactly the kind of contemporaneous evidence the ATO scrutinises. The full destination-side breakdown — bank introductions, BIC corporate-tax scope, property purchase mechanics, and the salaried/business activity routes — sits on the Monaco country page.
Step 4: Document the break and the new tie
Collect contemporaneously: the Monégasque carte de séjour, a registered lease or title deed, Monaco bank account statements, monthly utility bills (electricity, water, telecoms), private health insurance, school enrolment confirmation for any dependants, and — if applicable — an IRS-style attestation of the bank deposit and a tax-residency letter on Monaco government letterhead. Many Australian relocation files use the Monégasque “déclaration de résidence” plus the carte de séjour as the spine of the residency proof.
A material complication for Australians: there is no comprehensive Australia-Monaco double-tax agreement currently in force. Monaco’s treaty network is narrow and Australia is not within it. The practical consequence is that there is no Article 4 tie-breaker — domestic Australian law alone determines residency, and the case turns on the resides test, domicile test, and IT 2650 / Harding factors. Evidence of a settled Monégasque life — Monaco lease, Monaco bank, family relocation, a Monégasque school year for dependants, the disposal or arm’s-length leasing of the Australian principal residence — must be unambiguous, because no treaty backstop is available to rescue an ambiguous departure. CRS information exchange continues unaffected: both Australia and Monaco are CRS signatories, and your Monégasque bank balances are reported automatically to the ATO each year.
Step 5: First-year compliance in both jurisdictions
The departure-year Australian tax return is a “part-year resident” return covering worldwide income up to the date of cessation, the CGT Event I1 deemed disposal gains, plus any post-departure Australian-source income at non-resident rates (no tax-free threshold for non-residents — the bracket starts at 32.5% from dollar one up to AUD $135,000, then 37%, then 45%, with no Medicare levy). The section 104-165 election is made on this return. After departure, Australian-source income — rental from retained Australian real estate, Australian-source dividends, interest from Australian deposits, Australian-source employment income — remains in the Australian net at non-resident rates with 30% withholding on unfranked dividends, 10% on interest, and 30% on royalties, none reduced by treaty since the AU-MC DTA does not exist. Fully franked dividends remain exempt for non-residents but the franking credits are not refundable.
Australian superannuation is not deemed-disposed under CGT Event I1. Super interests are not CGT assets in the ordinary sense; preservation rules continue, you cannot access the balance until preservation age (60 for those born after 1964), and Australian citizens and PRs are not eligible for the Departing Australia Superannuation Payment (DASP) — DASP is restricted to former temporary visa holders. Leave the super untouched and plan a tax-efficient withdrawal at preservation age.
In Monaco, individuals do not file a personal income tax return — there is no such return. If you operate through a Monégasque company (SAM, SARL, SCS), you may be in scope of the 25% Impôt sur les Bénéfices to the extent more than 25% of turnover is generated outside Monaco; family-office and patrimonial structures that do not carry on commercial activity within Monaco are typically outside this net. Maintain a clean log of physical days in Monaco versus days spent in Australia — the ATO will request it first if your departure is reviewed.
Cost & Timeline
| Phase | Cost | Time |
|---|---|---|
| Tax planning + Australian/Monégasque legal review (pre-move) | AUD $20,000–AUD $50,000 | 2–4 months |
| CGT Event I1 modelling, market valuations, section 104-165 analysis | AUD $10,000–AUD $30,000 | 1–3 months |
| Monaco bank introduction + deposit (€500K–€1M+ tied locally) | €500,000–€1,000,000+ deposit + AUD $5,000–$15,000 advisory | 2–4 months |
| Housing — registered Monaco lease (≥12 months) or property purchase | €60,000–€240,000+/year rent or €500,000+ purchase | 2–6 months |
| Carte de séjour application + police interview | ~€10–€80 government fees + AUD $10,000–$25,000 advisory | 3–6 months |
| Move + setup (utilities, schools, health insurance) | AUD $20,000–AUD $60,000 | 1–2 months |
| Departure-year Australian return + ongoing Monaco compliance | AUD $8,000–AUD $20,000 | Annual |
| Total year-1 advisory + setup cost (excl. deposit & property) | AUD $90,000–AUD $250,000 | 6–12 months |
The deposit and any property purchase are not “cost” in the income-statement sense — they are capital tied up locally — but they must be financed in advance of the carte de séjour application. For a Sydney founder on AUD $1M of mixed income, the post-move annual cash saving (~AUD $400–450K) typically recovers the entire setup advisory layer within the first 6–12 months of Monégasque residency.
Treaty Considerations
There is no comprehensive Australia-Monaco Double Tax Agreement currently in force. Monaco’s treaty network covers a relatively short list — France (under the 1963 Convention), Luxembourg, Malta, Mauritius, Mali, Qatar, Saint Kitts and Nevis, Seychelles, and a handful of others — and Australia is not within it. This makes Australia-to-Monaco structurally similar to Australia-to-UAE: the question of where you are resident is decided exclusively under domestic law on each side — Australia applies its four-test framework and the IT 2650 / Harding factors; Monaco applies the carte de séjour requirements and the 183-day principle.
The practical effect is that the standard of evidence is higher than for treaty countries. The ATO is not bound by the Monégasque carte de séjour — it is at most persuasive evidence under the resides and domicile tests, not a determinative tie-breaker. Get the relocation right on the facts: family unit, principal residence, settled Monaco home, consistent days, and no “available for return” Australian dwelling. Australian-source dividend, interest and royalty withholding for non-residents falls back to statutory rates (30%, 10%, 30%) rather than reduced treaty rates, which materially increases the post-departure cost of holding income-producing Australian assets.
Common Mistakes
- Leaving the family in Australia while you live alone in Monaco. A spouse and minor children remaining in an Australian dwelling are a near-fatal residential tie under both the resides and domicile tests. Without a treaty tie-breaker, the ATO does not need much to land you back in Australian residency.
- Treating the Australian principal residence as “available” for visits. A house kept furnished, vacant, and ready for the family to return defeats the IT 2650 / Harding “permanent place of abode overseas” test. Either sell, or put it on a 12-month-plus arm’s-length lease.
- Ignoring crypto, private-company shares and foreign rentals in the CGT Event I1 calculation. Every non-TAP CGT asset is deemed-disposed at market value on the day of cessation — illiquidity is not a defence.
- Defaulting into the section 104-165 election by accident. The election is made by ticking a box on the return and is permanent. Review with an Australian-registered tax agent before lodging — for most Australia-to-Monaco profiles, paying the departure tax with the 50% discount and not electing is the cleaner answer because Monaco’s 0% personal CGT means subsequent gains will be entirely outside the Australian net.
- Underestimating Monaco’s French-national exclusion. Australian-French dual nationals must check carefully — French nationals settled in Monaco after October 13, 1962 are taxed under the 1963 Franco-Monégasque Convention as if they were French residents, which collapses the 0% benefit.
- Underestimating the absence of an AU-MC treaty. Australians who relocated to the UK or Singapore in the past sometimes assume Monaco will mirror those moves. It does not. The lack of a DTA changes both the residency tie-breaker (no Article 4) and the post-departure withholding cost on retained Australian assets.
FAQ
Will I still have to file in Australia after moving to Monaco?
Yes, in two scenarios. (1) The departure-year Australian tax return covers your worldwide income up to the date of cessation, the CGT Event I1 deemed disposal gains, the section 104-165 election if any, plus post-departure Australian-source income at non-resident rates. (2) Continuing Australian-source income — rental from retained Australian real estate (taxed at non-resident rates from the first dollar; no tax-free threshold), Australian-source business income, royalty income, and CGT on the eventual disposal of Taxable Australian Property — generally requires an annual non-resident return for as long as you have such income. Withholding handles most passive flows: 30% on unfranked dividends, 10% on interest, 30% on royalties, none reduced by treaty.
Can I keep my Australian bank account, super and property?
Yes to all three, with caveats. Banks reclassify the account as non-resident, applying 10% non-resident interest withholding. Australian super stays in place and remains tax-advantaged — preservation rules continue, contributions cease when employment income ceases, and access is restricted to preservation-age conditions of release. Citizens and PRs cannot use DASP. Australian real estate can be retained but the 50% CGT discount is denied on the portion of the gain accruing from 8 May 2012 onwards in non-resident periods, and the main residence exemption is largely denied to foreign residents under the post-30 June 2020 rules — selling the principal residence before departure typically preserves the exemption that a post-departure sale will lose.
What’s the minimum amount of capital I need to commit?
Realistically €1–2 million between (i) the bank deposit at a Monaco-licensed bank — formally €500,000+, but €1,000,000+ in practice for most HNW applicants — and (ii) housing, whether owned (entry-level apartments from €500,000+, central-district pricing typically €40,000–€60,000+ per m²) or rented (€60,000–€240,000+ per year for a family-suitable apartment). There is no Australian-specific surcharge — the same thresholds apply globally.
What if the ATO disputes my departure?
The dispute typically begins with an ATO query on the departure-year return, can escalate to a residency review, and ultimately to objection, the Administrative Appeals Tribunal and the Federal Court. Without an AU-MC DTA, Article 4 mutual agreement procedure is not available — the case is decided under Australian domestic law alone. The carte de séjour, registered Monaco lease, monthly Monégasque utility bills, family-relocation evidence, principal-residence sale or arm’s-length lease, and a clean physical-days log are the spine of the file. Cases like Harding turn on contemporaneous evidence of a permanent overseas home — keep the file from day one.
Does Australia tax me on the Monaco bank deposit interest?
Once you are non-resident under Australian domestic law, interest earned on a Monégasque bank deposit is foreign-source income and outside the Australian tax net. Monaco does not levy personal interest tax. The risk vector is residency itself — if the ATO successfully argues you remained Australian-resident in a given year, the worldwide-income principle pulls Monaco interest back into the Australian net at marginal rates. CRS reporting from the Monégasque bank to the ATO continues regardless.
How does this compare to Australia-to-UAE?
Both are 0% personal-tax destinations with no AU treaty, so the residency case is decided on domestic-law facts in either direction. The UAE is dramatically cheaper to enter (free-zone setup at AUD $8–25K versus €1–2M for Monaco), offers a more flexible 90-day hybrid residency test versus Monaco’s 183+ days, and has a 140+ country UAE treaty network for Australians who plan to retain investments globally. Monaco’s edge is European mainland location with full Schengen access, AAA jurisdictional stability, world-class private banking, and 0% inheritance tax to spouses and direct descendants — features that matter most to ultra-HNW families with European business or family interests. See Australia to UAE for the side-by-side.
Can I move back to Australia later?
Yes. There is no minimum non-residence period. If you re-establish residency under any of the four tests, you become Australian-resident again on that date, with a new acquisition cost equal to the fair market value on the day of becoming resident for assets that were previously deemed-disposed under CGT Event I1 (under the corresponding section 855-45 step-up). Assets in respect of which you elected under section 104-165 retain their original cost base on re-entry. Most cross-border advisors recommend a minimum 3–5-year non-residence horizon to avoid ATO arguments that the departure was not “genuine” within the meaning of the resides test.
