This seems to be right!
So, I called both Postfinance and TradeDirect.
TradeDirect is a QI and will do a W-8BEN. So I’ll have 15% withheld by US and 15% withheld by CH. It seems (but not sure) I should be able to recover both with tax return.
PostFinance is NOT a QI. So I’ll get 30% deducted by US. I’ll be able to get back only 15% from Swiss authorities, and need to go to IRS to get the remaining 15%.
I think that TradeDirect may be a good option for diversification: a bit expensive with 108CHF annual custody fee, but it’s “AA” rated and Swiss based, which is very good for diversification with respect to a US broker.
Also, I think that IRS tax return (for non-QI case) would be a lot of paperwork. Any experience on this?
Good thread!
Thanks!
