Here is the run down: A online only business selling private label dietary supplements in Texas. The supplements are manufactured and shipped by a separate corporation in a different state. I will be using a DBA because I want to use a company name. What licenses/permits do I need? What business structure would you recommend? Also advice on liability? This is what I think I"ll need: -DBA (registered business name) -File to trademark business name. (For copyright protection) -A Federal Tax ID (EIN) if not a sole-proprietorship (SSN for SP) -State Tax ID (not needed because of online only structure) -Permits and Business license? I'm not sure. Dietary supplements are considered a food item under FDA regulations.
