Online Sales Tax: location based on transaction server, shipping address, CC, or location of purchaser?
My company is UK based but many of my clients are based in the US, Canada and other parts of the globe. I intend to setup a system for my clients so that they can take payments from their customers who are based all over the world.
So, it will be my UK based system, on US servers, taking payments through a website from global customers, all paying directly into clients bank accounts.
Will I have to charge tax at the standard rate per client country or can I charge UK rates of tax as it is my company running the system?
