At least in MA, if I have no physical presence and made no revenue here I wouldn't have to register as a foreign corporation. I know that for sure. I hope it's similar for other states... Wasn't there a big deal about amazon avoiding even paying sales tax when shipping goods to a state that they didn't have a physical presence in? I have been assuming that providing a service to a client in another state while in MA would just be taxed in MA, the IRS certainly knows all about it but I don't know what business the other state would have given that I have no physical presence there.
