Taxes as a non-US resident
I have been looking into starting an LLC in the US, probably in either Wyoming or New Mexico. I want to know how my taxes would look like as a non-US resident operating the business from outside the country. My LLC would be selling a software for photography businesses. From some sources, I read that I would only be taxed on US-sourced income. For example, if I were to start the LLC in New Mexico and had customers all over the US, would I pay taxes for these customers? Would there be difference between customers in New Mexico and other states in the US? Would I have to pay taxes for any customers from Europe for example? Since my country has a tax treaty with the US, I can avoid being double-taxed as well? Thank you for your time
