It has been called a privately held corporation by its detractors so often that people believe this without doing any due diligence on their own.
The Federal Reserve has no articles of incorporation, no shareholders, no shareholder meetings, and does not file taxes in any jurisdiction.
It is part of the Federal Government not a private entity.
I am certain that I will get many negative comments on this post, but I doubt anyone will be able to point to any tax filings made by the Federal Reserve.
It seems that Fed employees know how to get rich betraying the public.
