I'm an Egyptian citizen, living in Egypt and I own a LLC in Wyoming. I am the only owner of this LLC (single member managed LLC). I use this company to accept international payments through stripe.com and Paypal on my website. I'm selling web design services only through my website. I've never visited the US before—the company was formed over the internet through a registered agent.
I was told that my LLC is a disregarded entity and there will be no federal taxes on my LLC but I'm supposed to file 1040NR form every year. I'm supposed to send the form from my country by regular mail after filling it to the IRS address in Austin, Texas.
My question is: will I fill 1040NR form with my details only and leave the rest blank? Do I have to fill schedule C form ? How can I correctly fill this forms for my LLC with no Income Effectively Connected With U.S. ?
