How to Invest in International Shares from Australia: VGS, US Stocks and Currency Risk

The ASX represents less than 2% of global share market capitalisation - a portfolio limited to Australian shares misses 98% of the world's public companies. International diversification is fundamental to a robust investment strategy:

• ASX concentration problem: The ASX is dominated by financials (banks - ~30%) and materials (miners - ~20%); holding only Australian shares creates significant sector concentration risk and limits exposure to technology, healthcare, and consumer sectors that drive global returns
• Global technology exposure: The top 10 US tech companies (Microsoft, Apple, Nvidia, Alphabet, Amazon, Meta, etc.) represent $15+ trillion in market cap; they are not accessible through any ASX-listed company; VGS provides exposure to all of them at once
• Historical return comparison: Over the 20 years to 2024, the MSCI World ex-Australia index has returned approximately 9-10% per annum in AUD terms; the ASX 200 Total Return index has returned approximately 8.5-9% - international shares have been roughly equivalent but with better sector diversification
• Currency as natural diversification: Holding unhedged international shares provides automatic exposure to the USD, EUR, JPY, and GBP; when the Australian dollar falls (as it typically does during recessions), international share values in AUD terms rise - providing a natural hedge against domestic economic downturns
• Franking credit trade-off: Australian shares provide grossed-up yields through the imputation system; international shares do not - dividends from US companies attract 15% US withholding tax (reduced by the Australia-US tax treaty) and no franking credits; the dividend advantage of Australian shares is partially offset by better growth in international shares
• Optimal allocation: Most diversified Australian portfolio models suggest 30-50% domestic (VAS) and 30-50% international (VGS/VGE) within the growth component of a portfolio - providing exposure to both the franking credit advantage and global growth

The choice between unhedged (VGS) and fully hedged (VGAD) international shares is one of the most debated questions in Australian portfolio construction:

• VGS (Vanguard MSCI Index International Shares ETF): Tracks MSCI World ex-Australia index; unhedged to AUD; MER 0.18%; includes large and mid-cap developed market companies from 23 countries; the most popular international ETF on the ASX
• VGAD (Vanguard MSCI Index International Shares ETF - Hedged): Same underlying index as VGS but currency-hedged to AUD; MER 0.21%; removes the daily currency fluctuation; effective return more closely tracks underlying share performance
• The hedging cost: Currency hedging has an embedded cost - in periods when the AUD interest rate is lower than foreign rates, you pay to hedge; in periods when AUD rates are higher, you receive a positive carry; in 2024-25 with AUD rates roughly similar to USD, hedging costs are moderate
• When unhedged (VGS) wins: When AUD depreciates against major currencies, your unhedged international holdings gain in AUD terms; historically, the AUD falls during global recessions precisely when other assets are also falling - providing a natural counter-cyclical buffer
• When hedged (VGAD) wins: When AUD appreciates strongly (e.g., commodity boom), your unhedged holdings lose value in AUD terms even if the underlying shares rise; VGAD removes this drag
• Academic evidence: Research by MSCI and Vanguard consistently shows that for long-term investors (10+ years), unhedged international shares produce slightly lower volatility-adjusted returns than hedged, but the difference is modest; the tax efficiency and tracking simplicity of unhedged is favoured
• Practical recommendation: Most Australian financial planners and portfolio models use unhedged international ETFs (VGS) as the primary international allocation; VGAD is used by those who specifically want to minimise currency volatility or who are approaching retirement

Some Australian investors prefer to hold individual US shares directly through platforms like Interactive Brokers, Stake, or Superhero. Several tax and regulatory issues arise:

• W-8BEN form: Any Australian resident investing in US securities must complete a W-8BEN (Certificate of Foreign Status of Beneficial Owner) - this certifies to US brokers that you're a non-US person and enables the Australia-US tax treaty withholding rate of 15% on dividends (vs 30% for those without a treaty)
• Dividend withholding tax: US companies withhold 15% tax on dividends paid to Australian residents who have completed a W-8BEN; this 15% is a foreign tax credit you can claim in your Australian tax return - reducing your Australian income tax by the amount already withheld
• Capital gains - US rules for non-residents: Australia-resident investors pay no US capital gains tax on the sale of US listed shares (as non-resident aliens, gains from publicly-traded securities are generally not US-taxable); capital gains are taxed only in Australia under Australian CGT rules
• Foreign exchange considerations: Buying US stocks involves converting AUD to USD; each buy and each sell creates a foreign exchange event; the ATO requires you to translate all foreign currency amounts to AUD at the time of the transaction for CGT and income purposes - use the RBA daily exchange rate
• Cost base in AUD: Your cost base for CGT is the AUD equivalent of what you paid in USD on the purchase date; when you sell, proceeds are translated to AUD at the sell date rate; AUD appreciation between purchase and sale reduces your gain; AUD depreciation increases it
• PFIC rules for US investors: If you are a US citizen or green card holder living in Australia, many Australian investment vehicles (managed funds, ETFs, super) are classified as Passive Foreign Investment Companies (PFICs) under US tax law - this creates punitive US tax treatment; seek US-specialist tax advice in this situation
• Franked dividend equivalents: US shares do not carry franking credits; a 3% US dividend yield is 3% after the 15% withholding credit is applied in your Australian return - compare to a 3.5% fully-franked Australian dividend grossed-up to ~5% for a like-for-like comparison

Australian investors who hold US-sited assets directly face potential US estate tax exposure at death - one of the most overlooked risks in direct US investing:

• US estate tax for non-resident aliens: The US imposes estate tax on US-sited assets owned by non-US persons at death; US estate tax rates range from 18-40% on the taxable estate above $60,000 (the non-resident alien exemption)
• $60,000 exemption: Non-resident alien estates receive a $60,000 exemption on US-sited assets - compared to the $13.6 million exemption for US citizens/residents in 2024; this means even a modest direct holding in US shares can create a US estate tax liability
• What counts as US-sited assets: Shares in US-incorporated companies held directly; US real property; certain US bonds; partnership interests in US partnerships; NOT: ASX-listed ETFs (e.g., VGS) that hold US stocks - the ETF is an Australian-domiciled fund
• VGS eliminates US estate tax risk: Holding US shares via an ASX-listed ETF (VGS, DHHF, IVV structured as Australian fund) means you own units in an Australian trust, not directly in US companies; Australian trust units are NOT US-sited assets; no US estate tax exposure
• Interactive Brokers / Stake direct holdings: If you hold $100,000+ in US shares directly on a US broker platform, you may have a US estate tax liability at death; the Australia-US tax treaty provides some relief but it is complex; consult a US-Australian tax specialist if your direct US holdings exceed $100,000
• Practical advice: For most Australian retail investors, ASX-listed ETFs (VGS, IVV as an Australian domiciled fund) are the better vehicle for international exposure - they eliminate US estate tax exposure while providing equivalent investment outcomes
• Australian CGT on death: Remember that while Australia has no estate tax, assets passing to beneficiaries at death are subject to CGT when the beneficiary eventually sells (they inherit the deceased's cost base) - plan estate transfers of appreciated international share portfolios carefully

International shares create more complex tax reporting obligations than domestic ASX investments. Staying on top of these prevents ATO compliance issues:

• Foreign income in your tax return: All dividends and interest from international investments are included in your Australian tax return as 'other foreign income'; declare the gross amount (before foreign withholding tax) and then claim the foreign tax credit as an offset
• Foreign tax credit (FTC): The FTC prevents double taxation - if you paid 15% US withholding on a US dividend, you can offset that 15% against your Australian income tax on the same amount; the FTC cannot exceed the Australian tax on the foreign income
• PAYG withholding pre-fill: Unlike ASX dividends (which pre-fill from STP), foreign dividends do NOT automatically pre-fill in myTax - you must manually enter these from your brokerage statements; underreporting foreign income is an ATO audit trigger
• ATO data matching: The ATO receives data from Australian banks and brokers about foreign payments and currency conversions; since 2019, they have also increased information sharing with the IRS and OECD partners - don't assume foreign income is invisible
• Reporting threshold - foreign financial accounts: Australians holding foreign financial accounts with balances above $50,000 AUD equivalent should be aware of FATCA (Foreign Account Tax Compliance Act) and CRS (Common Reporting Standard) reporting - these are bank reporting obligations, not direct filing requirements for individuals, but the ATO receives the data
• Sharesight for international portfolios: Sharesight handles foreign currency translation, dividend tracking, CGT lot management, and produces an ATO-ready report; essential for investors with international holdings across multiple currencies
• Foreign income averaging: For large one-off foreign capital gains, Australian tax law does not have a foreign income averaging mechanism - the gain is assessed in full in the year of disposal; timing large foreign asset sales across financial years can reduce marginal rate impact
