(a) Additional information required. If later regulations issued under the section of the Code or of the Subchapter S Revision Act of 1982 under which the election, consent, or refusal was made require the furnishing of information in addition to that which was furnished with the statement of election, consent, or refusal as provided by part 18 of this title, and if an office of the Internal Revenue Service requests the taxpayer to provide the additional information, the taxpayer shall furnish the additional information in a statement filed with that office of the Internal Revenue Service within 60 days after the date on which the request is made. This statement shall also—

(1) Contain the name, address, and taxpayer identification number of each party identified in connection with the election, consent, or refusal,

(2) Identify the election, consent, or refusal by reference to the section of the Code or Act under which the election, consent, or refusal was made, and

(3) Specify the scope of the election, consent, or refusal.

If the additional information is not provided within 60 days after the date on which the request is made, the election, consent, or refusal may, at the discretion of the Commissioner, be held invalid.

(b) State law incorporator. For purposes of any election, consent, or refusal provided in part 18 of this title, any person who is considered to be a shareholder for state law purposes solely by virtue of his or her status as an incorporator shall not be treated as a shareholder.
