A group of friends are going to create a non-resident LLC in the USA. My question is how can we be paid as company founders? Would be possible to be registered as self-employed in our respective countries and send invoices to our own company? Will that be fine?
[F]oreign owners may act as consultants to the LLC under a written Consultant’s agreement completing all consulting work within their home country and billing the LLC in the United States for this service. By doing so, it may be possible to eliminate profits thus avoiding some taxation, as well as U.S. situs (located) earnings, which would be subject to the U.S. tax regime, even for non-residents.
But read the entire article I linked to.
