US withholding tax on T2
My client who operates his consulting practice through a corporation has a client who told him for the work that he performs when he is physically in the US (very few days), the IRS now requires them to withhold US taxes a source.
I believe this is incorrect and only applies to a sole proprietor practice. Does anyone have any experience with this?
They are also asking him to file one of the W-8 forms, but not sure which one to file.
Any help would be appreciated.
