I thought the U.S.' 30% withholding tax is only on dividends. But I noticed that my U.S. broker is withholding on ST capital gains as well. And they tell me they will withhold 30% on LTCG and interest as well.
I am aware that there is a new rule about withholding; but I thought it doesn't go into effect until 1/1/2013. Any insight would be appreciated.
Also, the "financial institution" can avoid the withholding if they sign some kind of agreement with the IRS. But I am not clear about the definition of "financial institution". Is it the broker in this case?
And does anyone know whether the IRS has published a list of FFIs who have "Chapter 4" agreement with them?
TIA
