Maybe someone already ask this;but I can't find it,lol. If I start out part time instead of FT do I still need to apply for a business license and/or EIN number? For example buy one or two items a week and sell/auction it on Ebay. Eventually once I have enough cash flow going I would like to open a store then I'm pretty sure I'll need all the stuff to run it full time. And one last thing does the IRS put a limit on stuff a person sells before you need to get a license/EIN? Thanks! :? :? :? :
