In addition to any criminal penalty provided by law, if any notice or return required to be filed by section
6048—
the person required to file such notice or return shall pay a penalty equal to the greater of $10,000 or 35 percent of the gross reportable amount. If any failure described in the preceding sentence continues for more than 90 days after the day on which the Secretary mails notice of such failure to the person required to pay such penalty, such person shall pay a penalty (in addition to the amount determined under the preceding sentence) of $10,000 for each 30-day period (or fraction thereof) during which such failure continues after the expiration of such 90-day period. At such time as the gross reportable amount with respect to any failure can be determined by the Secretary, any subsequent penalty imposed under this subsection with respect to such failure shall be reduced as necessary to assure that the aggregate amount of such penalties do not exceed the gross reportable amount (and to the extent that such aggregate amount already exceeds the gross reportable amount the Secretary shall refund such excess to the taxpayer).
