IVV vs VGS vs VTS: Which US or Global Shares ETF Is Right for You? (2026)
IVV, VGS, and VTS are the three most popular international shares ETFs for Australians. IVV is US-only at 0.04%. VGS is global developed at 0.18%. VTS is US-domiciled with W-8BEN complexity. Here's the complete comparison.
For Australian investors wanting international shares exposure, three ETFs come up constantly: IVV (iShares S&P 500), VGS (Vanguard MSCI World ex-Australia), and VTS (Vanguard US Total Market). Each has different coverage, fees, domicile, and tax implications. Here is the full comparison.

IVV — The Cleanest US Shares ETF for Australians
IVV is the most popular US shares ETF for Australian investors. It is ASX-listed (Australian-domiciled), charges 0.04% MER, and tracks the S&P 500 — 500 of the largest US companies.
Key advantages:
- Australian-domiciled — no US estate tax risk, standard ASX brokerage, standard tax treatment
- Second lowest MER available (VTS is 0.03% but has significant complications)
- The S&P 500 covers approximately 80% of US market capitalisation by value
- $12.8B AUM — one of the largest ETFs on the ASX
What IVV misses: Smaller US companies (covered by VTS) and non-US developed markets (covered by VGS). For a concentrated US mega-cap allocation, IVV is the cleanest choice.
VGS — Broadest Developed Market Coverage
VGS tracks the MSCI World ex-Australia Index — approximately 1,500 companies across 22 developed markets including the US (73% weight), Japan (6%), UK (4%), France (3%), Canada (3%), and others.
Key advantages:
- Broadest developed market coverage — not just US exposure
- Australian-domiciled — no US tax complications
- 10-year track record
What VGS misses: Emerging markets (China, India, Brazil, etc. — covered by VGE separately) and Australian shares (covered by VAS/A200).
For investors who want true global diversification rather than just US exposure, VGS (or its cheaper equivalent BGBL at 0.08%) is the better choice over IVV.
VTS — The Complicated Option
VTS is Vanguard's Total US Market ETF — but it is listed on the New York Stock Exchange, not the ASX. This creates three significant complications for Australian investors:
1. US estate tax risk: US-domiciled ETFs are subject to US estate tax for non-US residents on holdings above approximately USD $60,000. For Australians with large VTS positions who die unexpectedly, the US estate tax liability could be significant. Australian-domiciled IVV and VGS have no such risk.
2. W-8BEN form: To buy VTS, you must complete IRS Form W-8BEN with your broker, certifying you are a non-US person. This reduces the withholding tax on distributions from 30% to 15% under the Australia-US tax treaty. It requires renewal every 3 years.
3. US brokerage required: Standard Australian brokers like CommSec, Pearler, and Selfwealth allow VTS purchases, but the process is less seamless than ASX-listed ETFs. Not all platforms support it.
The only advantage of VTS: Its 0.03% MER is lower than IVV's 0.04%. On $100,000, this saves $10/year. This is not worth the estate tax risk and administrative complexity for most Australian investors.
Verdict: Most Australian investors should use IVV instead of VTS. The $10/year fee saving is not worth the complications.
Which Should You Choose?
Choose IVV if: You want concentrated US exposure (S&P 500) at minimal cost, without any foreign domicile complications. This is the recommended choice for most Australians wanting US shares.
Choose VGS (or BGBL) if: You want broader international diversification beyond the US — Europe, Japan, and other developed markets alongside the US. VGS gives you 22 countries in one fund.
Avoid VTS for most Australians: The estate tax risk, W-8BEN requirement, and complexity are not justified by the 0.01% fee saving over IVV.
The common combination: VAS (Australian shares) + BGBL or VGS (global developed) covers the entire global developed market at low cost without US tax complications.
Frequently Asked Questions
Is IVV or VGS better for Australians?
IVV gives you US-only exposure (S&P 500) at 0.04% — ideal if you want concentrated US mega-cap exposure. VGS gives you 22 developed markets at 0.18% — ideal for true global diversification. Both are ASX-listed with no US tax complications. For a single international ETF covering more than just the US, VGS (or the cheaper BGBL at 0.08%) is the broader choice.
Is VTS safe for Australian investors?
VTS (Vanguard US Total Market) is US-domiciled, creating potential US estate tax exposure for non-US residents above approximately $60,000 USD. For most Australian investors, the ASX-listed IVV (Australian-domiciled, S&P 500) is a safer and simpler alternative with nearly identical US exposure at 0.04% versus VTS's 0.03%.
What is the difference between IVV and VGS?
IVV tracks the S&P 500 (500 largest US companies). VGS tracks the MSCI World ex-Australia (~1,500 companies across 22 developed markets). IVV is US-only; VGS is global. IVV has a lower MER (0.04% vs 0.18%). The US represents approximately 73% of VGS — so VGS provides meaningful additional diversification into Europe, Japan, and other markets that IVV excludes.
