I just came across some US tax forms for "alien"foreign entities like W-8BEN-E and 1040NR which made me ask this question.
Suppose a company called Cool Stuff Ltd. (incorporated outside of the US) runs some sort of online business serving customers all over the world (could. This could be news/mediapaid content subscriptions, dating, posting classifieds etc.)ads/classifieds, hosting, VPN — all sorts of stuff that is performed by software accessible by customers over the Internet.
The company is not present in the US in any way: no incorporation, no offices, no employees, no web hosting, the shareholders and directors are not related to the US at all.
People in the US visitors can access the company's website/app and buy services in the company's home country currency. The company may not even care or take note of where they are from.
Technically, if any single John Doe from the US decides to buy a subscription, he will make the company "receive" "income" "from U.S. sources that consists of" "Compensation for, or in expectation of, services performed" (cited from WW-8BEN-E).:
Does that really trigger the company's obligation to fill US tax forms and pay tax in the US? If so, is there any threshold i.e. minimum income that triggers the obligation?
