If I have an online business in NJ must I file incorporation paperwork in all states I am doing business in?
Let me clarify. If I am running an online candy business from my home in NJ and my customers are both from NJ and other states, must I have paperwork (incorporation, tax ID, etc) filed in every state or just in NJ? If so, what would I need to file? I just want to make sure I have everything I need before starting my business.
