(a) Penalty imposed. A taxpayer who fails in a material way to disclose one or more positions taken for a taxable year, as required by section 6114 and the regulations thereunder, is subject to a separate penalty for each failure to disclose a position taken with respect to each separate payment or separate income item in the amount of -
(1) For a corporation taxable as such under the Code $10,000; or
(2) For all other taxpayers, $1,000.
(b) Penalty waived. Pursuant to the authority contained in section 6712(b) of the Code, the penalty imposed by paragraph (a) of this section may be waived, in whole or in part, if it is established to the satisfaction of the Assistant Commissioner (International), the District Director or the Director of the Internal Revenue Service Center that the taxpayer's failure to disclose the required information was not due to willful neglect. An affirmative showing of lack of willful neglect must be made in the form of a written statement that sets forth all the facts alleged to show lack of willful neglect and contains a declaration by such person that the statement is made under the penalties of perjury.
