Hello.

I am a Non-Resident Alien looking to start a Single-Member LLC to do Web Design in the US. The LLC will have no US presence, no office, with all the activities exclusively done from my home country (although the money is collected in an US bank account). My understanding is that this would be a Disregarded Entity and that this income is NOT US Sourced since this falls under "Personal Services", for which the Source is "Where Services are Performed", which is my home country. I believe this means I owe no income tax.

In this case, what do I file/report to the IRS?
Nothing? In that case, how will they know the money going through the bank account is legally not taxed?
Or should I file a 1040NR even though I owe no income tax?

Additionally, I'd like to know what other requirements are asked of me:
1) Do I need to file/report anything else?
2) Do I need to do bookkeeping? If so, do I need to file this bookkeeping?
Basically is there anything else I need to do or report in order to do this legally?

Thank you so much for any help! This is very much appreciated.
