What do I need to do to start a new business in Missouri. I plan on starting out on my own and only using help ocasionally. I think I can pay them as contract labor and simplify some things. I already registered my business name with the state, and im going to find out about a county business license tommorow. Do I need a federal tax ID number and if so who do I contact. Also, what companies offer affordable liability insurance. What information will my bank most likely want to open a business account. I know thats a lot of questions but I dont want to go into this completely blind. Im not concerned with any type of professional licenses or applicators license at this time, that will come later.
