It's time for me to fill out the W-8BEN form again. It's been ages since Ive filled one out and Ive forgotten some of the fine details like the amount of tax to be withheld. Australia has a tax treaty with the US so it will only be a very small percentage that will be withheld. Surprisingly, I couldn't find any such information online about the exact amount. Another Australian stock photographer on another forum assured me that it was 5%. Though today, I managed to download an old W-8BEN form that I had previously completed and it says 0.5%. So now I'm not sure whether I should put 0.5% or 5% on the new form. Would anyone here know?
