You cannot live in North Carolina and join Amazon.
The law is similar to the one in NY but interpretation may differ. In NY doesn't matter where you incorporate if you still live in NY you can create a nexus and out of state merchants would have to collect & remit sales tax
if sales threshold is met. Our initial review of the NC law indicates the same but we are in process of trying to verify. If possible consult your own lawyer.
Luckily, there are still many quality merchants that will allow you to join their programs. It is a matter of finding them. Search through the networks to find some great merchants. It will take several merchants to fill the place of Amazon but as many have learned, that diversification is the best avenue. Never, ever become dependent on just a couple merchants.
