I'm from Guatemala and i own a company here with license to export.
Two days ago I ask another question here: Tax deduction for imported IT goods and services and @littleadv has given me a very helpful and informative answer.
Now I'm trying to find the best way to sell my products and services (Software & IT Support) in USA and Worldwide via an US based company (that i'll setup).
I know that each state have different tax regulations and laws (for the state) behind federal taxes, also that states like Delaware, Wyoming and Nevada doesn't have sales tax (is this true?).
In many questions in this site and some blogs posts around the web I see that tax apply only for US income.
The question is, how to identify if the income can be tagged as US income.
If I sell a product to a customer in any US state, of course, this is a US income. But, what's about a sale to a customer in Spain, Mexico, Japan, or any other country. They will pay by Paypal or WireTransfer to the company account.
Can this be considered as US Income?
In advance, thanks for your generous assistance.
