2009 California Revenue and Taxation Code - Section 11271-11273 :: Article 2. Reports

11271.  (a) Every person whose private railroad cars are operated
upon the railroads in this state at any time during a calendar year
shall file with the board on or before April 30 a report under oath
setting forth specifically the information prescribed by the board to
enable it to make the assessment required in this part.
   (b) In the case of a corporate owner of property, the property
statement shall be signed either by an officer of the corporation or
by an employee or agent who has been designated in writing by the
board of directors to sign such report on behalf of the corporation.

11272.  The board for good cause may extend for not to exceed 30
days the time for making a report, provided a written request is
filed with the board prior to the period for which the extension may
be granted.

11273.  If any person required to file a report fails to file it on
or before April 30 or at the time as extended by the board, a penalty
of 10 percent of the assessed value shall be added to the
assessment.
   If the assessee establishes to the satisfaction of the board that
the failure to file the property statement timely was due to a
reasonable cause and occurred notwithstanding the exercise of
ordinary care and the absence of willful neglect, the board shall
order the penalty abated, provided the assessee has filed with the
board written application for abatement of the penalty within the
time prescribed by law for filing a petition for reassessment.
