I'm planning on registering an LLC in Wyoming. I don't live in the US neither I have ever visited. I'm actually a Pakistani and live in Karachi. I came across some consultants they offered me their services. I did some research and found out that Wyoming is a business-friendly state when it comes to taxation. My services will be online bookkeeping/accounting, financial modeling, and analysis. There PROBLEM is that I don't know if I'll have to charge sales tax? Also what kind of taxes will I be paying, I mean there's got to be some. Need your help.
