Sole Proprietor and Sole Proprietorship
A Sole Proprietor is an individual who undertakes to engage in business without partners and without organizational forethought. This does not mean that you have one person, but that you have one owner. There is almost never a reason to operate as a sole proprietorship, as a sole proprietorship does not offer the liability protection that an entity does. Please consult with an attorney.
