You need a W-8BEN only for ETFs that are US-domiciled. On the ASX the best known are VTS and VEU (Vanguard) and SPY (State Street). IVV does not need one. It was converted to an Australian fund in 2018, as were most iShares international ETFs. Nor do VGS, BGBL, NDQ or other Australian unit trusts. Without the form, the US withholds 30% of the distributions from a US-domiciled ETF. With it, Australians generally pay 15%, which you can usually claim as a foreign income tax offset. The form is free, takes five minutes online through the share registry and lasts about three years.
Why some ASX ETFs are really US funds
An ETF's domicile is the country where the fund itself is set up. Most ETFs on the ASX are Australian unit trusts, even when everything they own is overseas. A few are US-listed ETFs made available here through CHESS Depositary Interests (CDIs). When you buy one of those, you own an interest in a US fund.
That matters because the US treats you as a foreign investor in a US company. It taxes the distributions at source, and it wants to know which country you live in so it can apply the right tax treaty rate. The W-8BEN is how you tell it.

Money in US-domiciled vs Australian ETFs with US exposure
How to check any ETF: look at the issuer's fund page or the product disclosure statement. If it says the fund is domiciled in the United States, or that you're buying CDIs over a US fund, you need the form. If the issuer is an Australian responsible entity offering units in an Australian trust, you don't.
What the W-8BEN actually does
Without a valid W-8BEN, the US withholds tax at the full 30% from distributions paid by a US-domiciled ETF. With one, the Australia-US tax treaty generally cuts that to 15% on dividends.
US tax withheld, with and without the form
Either way, you're not taxed twice. The US tax withheld is shown on your annual tax statement and you can usually claim it as a foreign income tax offset on your Australian return. The form doesn't change how much tax you pay overall at 15%. It stops you losing the extra 15%, which is hard to get back.
How to lodge a W-8BEN
- Where: through the ETF's share registry (Computershare for the Vanguard US ETFs), usually online. Some brokers prompt you when you first buy.
- Who signs: each individual owner. SMSFs, companies and family trusts need the entity version, the W-8BEN-E.
- What you need: your name, address, country of tax residence (Australia) and Australian tax file number. No US tax number is needed for the treaty rate.
- How long it lasts: until 31 December three years after you sign. A form signed in June 2026 lasts until 31 December 2029. Lodge a new one if your details change.
The bigger issue for larger balances: US estate tax
For people in their 50s, 60s and 70s, this matters more than the form. Units in a US-domiciled ETF are US assets. If a non-US person dies holding more than US$60,000 of US assets, their estate can be liable for US estate tax. The Australia-US estate tax treaty can reduce or remove it for many estates, but it means US paperwork for your executor, and you may need specialist advice.
Australian-domiciled ETFs such as IVV, VGS and BGBL avoid this, because you own units in an Australian trust, not US assets. That's one reason many retirees and SMSFs prefer them for large US holdings, even when the fee is a touch higher.
Fee for US and global shares ETFs
The fee gap between IVV and VTS is just 0.01% a year, or $10 a year on $100,000. For most Australian investors the simpler tax position of an Australian fund is worth more than that. See IVV vs VGS vs VTS or compare IVV and VTS side by side.
Other differences with US-domiciled ETFs
- No franking or Australian tax components. Distributions are foreign income, paid in US dollars and converted.
- Fewer reinvestment options. Many US-domiciled ETFs on the ASX, SPY included, offer no distribution reinvestment plan.
- Distributions arrive later. The US fund pays first, and the Australian payment follows a couple of weeks later.
- Tax statements look different. You get a US-style annual statement rather than the usual Australian AMIT statement.
Common questions
Does IVV need a W-8BEN form?
No. IVV has been an Australian-domiciled fund since BlackRock's 2018 restructure. US tax is dealt with inside the fund and passed through to you as a foreign income tax offset.
Does VTS need a W-8BEN form?
Yes. VTS is a US-domiciled Vanguard ETF quoted on the ASX. Without a W-8BEN, 30% US withholding applies to its distributions, rather than the 15% treaty rate.
Is SPY on the ASX a US fund?
Yes. ASX-listed SPY is a CHESS Depositary Interest over the US-listed SPDR S&P 500 ETF Trust, so a W-8BEN applies. IVV tracks the same index as an Australian fund.
How often do I need to renew a W-8BEN?
It stays valid until 31 December three years after the year you sign it, unless your details change.
Do VGS, BGBL or NDQ need a W-8BEN?
No. They are Australian unit trusts. You don't need any US forms, even though they hold US shares.
