IVV vs VGS vs VTS (2026): Fees, Tax & Which Is Best for Australians

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. Since March 2026 there's a fourth contender: Vanguard's Australian-domiciled S&P 500 ETF, V500, covered below. Here is the full comparison.

Quick answer: IVV vs VGS comes down to US-only or global. IVV (0.04% p.a.) holds the 500 largest US companies; VGS (0.18% p.a.) holds about 1,250 companies across the US, Japan, Europe and other developed markets, with the US at about three-quarters. VGS vs VTS is a different question: VTS (0.03% p.a.) is US-only like IVV, but it is a US-domiciled fund, so it brings a W-8BEN form and US estate tax exposure that VGS and IVV don't. For most Australians, IVV or V500 for US-only and VGS or BGBL for global is simpler.

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 available US market capitalisation

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 1,250 holdings across 22 developed markets including the US (74% weight), Japan (6%), the UK (3.5%), Canada (3.3%), France (2.3%) and others (MSCI index factsheet, 30 September 2026).

Key advantages:

• Broadest developed market coverage — not just US exposure
• Australian-domiciled — no US tax complications
• Trading on the ASX since November 2014, with A$16.9 billion in the ETF at the June 2026 quarter

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 the cheaper BGBL at 0.08%) is the better choice over IVV.

VGS vs VTS: global or US total market

These two get compared because both are Vanguard and both are popular, but they do different jobs:

If you want one fund for everything outside Australia, VGS does that and VTS doesn't. If you only want the US, VTS is cheaper on paper, but IVV or V500 give you nearly the same exposure without the US-domicile paperwork described below.

VTS — The Complicated Option

VTS is Vanguard's US Total Market ETF, renamed the Vanguard Morningstar US Total Market Shares Index ETF from 30 July 2026 after Morningstar acquired its previous index provider. Vanguard says its investment approach is unchanged. You can buy it on the ASX like any other ETF, but the fund itself is domiciled in the United States — it's the US-listed fund, quoted in Australia. That creates complications for Australian investors that IVV, VGS and V500 don't have:

1. US estate tax risk: If a non-US resident dies holding US-domiciled assets worth more than US$60,000, their executor must file a US estate tax return. 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. A W-8BEN generally expires at the end of the third calendar year after signing, so it has to be renewed.

3. Not every platform supports it: because VTS is a US fund quoted on the ASX, some Australian platforms can't hold it or require extra steps. Check your broker before you plan a portfolio around 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 or V500 instead of VTS. The $10/year fee saving is not worth the complications.

V500 — Vanguard's Australian-domiciled S&P 500 ETF

Vanguard launched V500 (Vanguard S&P 500 US Shares Index ETF) on the ASX on 4 March 2026, with a 0.07% management fee and a currency-hedged sibling, V5AH, at 0.09% (Vanguard ETFs at a glance). Like IVV, it's Australian-domiciled, so there's no W-8BEN form and no US estate tax exposure.

IVV is still cheaper and far larger. V500's ETF size was about A$144 million in the June 2026 quarter. V500's main appeal is for investors on Vanguard Personal Investor, where buying Vanguard ETFs costs $0 brokerage, so regular small purchases of V500 can work out cheaper overall than paying brokerage to buy IVV elsewhere.

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 V500 if: You want the same S&P 500 exposure but invest through Vanguard Personal Investor, where Vanguard ETF purchases are brokerage-free.

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.
