A scenario: I am selling online software and I provide advanced features for premium members. As far as I understand I do not ship or deliver anything physically. I also do not ask customers for their address information and can accept any payment (e.g., bitcoin).


What sales tax do I charge if I do not know their county and address? Can I assume that the sale happened at my "store's" location and charge them a standard sales tax based on that?



Destination-based sales tax collection. What if you do not know the destination's address?
