Lady Gaga plans to start at least two different business activities after graduating with a masters in accountancy, from world renowned Sacramento State University. She will apply the knowledge gained in her business courses to use various forms of social media to promote her skills and experience as a musician to help younger musicians develop their skills. She plans to generate income from advertising on her social media sites. She also will use her artistic and marketing talents to find work for herself and the young musicians she will be training. Based on what she has learned, she is wondering if she should from a corporation, limited liability company or just be a sole proprietor. She is also curious whether for tax and legal purposes, she should have one business or two. Please advise Lady Gaga as to her best plan of action.
