Hi, if I invest in a US domiciled ETF and earn some dividends, which are withheld by the US government at a 15% rate, by how much can I reduce the Australian taxes I have to pay? Is the offset on a dollar-for-dollar basis, i.e. the reduction in my Australian tax equals the US tax I have paid?
Also, given that the 15% tax on the dividends is a withholding tax and I don't think I have to file a tax return in the US for that (i.e. the tax money is simply grabbed by the US government when the transaction occurs, and no subsequent paperwork is involved), how can I prove to the ATO the amount of tax I have paid in the US?
Thanks a lot!
