Write a letter advising a hypothetical sole proprietor to choose another form of business ownership. By definition, a sole proprietorship is an unincorporated business owned by one person known as the sole proprietor. The majority of U.S. businesses are owned and operated as sole proprietorships. In a persuasive paragraph, write a letter to a hypothetical sole proprietor explaining why he or she should convert the sole proprietorship to another form of business ownership (for example, a traditional "C" corporation, an "S" corporation, or a limited liability company).
