Is a sole proprietorship a reporting company?

No, unless a sole proprietorship was created (or, if a foreign sole proprietorship, registered to do business) in the United States by filing a document with a secretary of state or similar office. An entity is a reporting company only if it was created (or, if a foreign company, registered to do business) in the United States by filing such a document. Filing a document with a government agency to obtain (1) an IRS employer identification number, (2) a fictitious business name, or (3) a professional or occupational license does not create a new entity, and therefore does not make a sole proprietorship filing such a document a reporting company.
