Just trying to understand how the US Dividend taxation works if I have an UK S&S ISA and buy an US stock. I understand we pay 15% tax on US dividends (providing we fill the W-8BE form), but is that taken at source? How does it work if you buy through an ISA?
Let’s say I bought ExxonMobil that paid $0.87/share, I would only receive $0.74/share on my ISA account and won’t need to worry about filling tax forms, etc? Or will I be exempt because I have a S&S ISA and receive the full $0.87 amount?
