(C) Split-interest trusts In the case of a trust which is required to file a return under
section 6034(a), subparagraphs (A) and (B) of this paragraph shall not apply and paragraph (1) shall apply in the same manner as if such return were required under
section 6033, except that—
(i) the 5 percent limitation in the second sentence of paragraph (1)(A) shall not apply,
(ii) in the case of any trust with gross income in excess of $250,000, the first sentence of paragraph (1)(A) shall be applied by substituting "$100" for "$20", and the second sentence thereof shall be applied by substituting "$50,000" for "$10,000", and
(iii) the third sentence of paragraph (1)(A) shall be disregarded.
In addition to any penalty imposed on the trust pursuant to this subparagraph, if the person required to file such return knowingly fails to file the return, such penalty shall also be imposed on such person who shall be personally liable for such penalty.
