(b) Exceptions for certain transfers to foreign partnerships; special rule (1) Exceptions Subsection (a)(1)(B) shall apply to a transfer by a United States person to a foreign partnership only if— (A) the United States person holds (immediately after the transfer) directly or indirectly at least a 10-percent interest (as defined in section 6046A(d)) in the partnership, or (B) the value of the property transferred (when added to the value of the property transferred by such person or any related person to such partnership or a related partnership during the 12-month period ending on the date of the transfer) exceeds $100,000. For purposes of the preceding sentence, the value of any transferred property is its fair market value at the time of its transfer. (2) Special rule If by reason of an adjustment under section 482 or otherwise, a contribution described in subsection (a)(1) is deemed to have been made, such contribution shall be treated for purposes of this section as having been made not earlier than the date specified by the Secretary. (c) Penalty for failure to furnish information (1) In general If any United States person fails to furnish the information described in subsection (a) at the time and in the manner required by regulations, such person shall pay a penalty equal to 10 percent of the fair market value of the property at the time of the exchange (and, in the case of a contribution described in subsection (a)(1)(B), such person shall recognize gain as if the contributed property had been sold for such value at the time of such contribution). (2) Reasonable cause exception Paragraph (1) shall not apply to any failure if the United States person shows such failure is due to reasonable cause and not to willful neglect. (3) Limit on penalty The penalty under paragraph (1) with respect to any exchange shall not exceed $100,000 unless the failure with respect to such exchange was due to intentional disregard.
