You need a Business Plan and a business banking account to set up in business,legallyso unless its something like Ebay, I don t know how you can until you are legally old enough to work and contribute via N.I. and tax
no your too young in any state in the USA don t care what class restrictions thier is either YOU must be of legal age to have your own business so get the business under an adult family member name and lots of luck i wish you
