Hi. I’m non-US author. My country allows me to claim a 0% rate of withholding (Yes, I’m lucky :-)). In the W8 form I can put U.S. Social Security Number. Can I still claim a 0%? I’m a bit confused after reading this natman’s post. It says I can put either Foreifner TIN or ITIN (and nothing about SSN). Please clarify.
