Article 2. Errors On The Board Roll

4876.  When it can be ascertained from any roll or from any papers
of the board what was intended or what should have been assessed,
defects in description or form or clerical errors of the board in
assessing state-assessed property or other errors of the board not
involving the exercise of judgment as to value which result in the
entry on the roll of assessed values other than those intended by the
board may be corrected by the board under this article at any time
within four years after the assessment was made or within the period
for which a waiver is given pursuant to Section 868.



4876.5.  When it can be ascertained by the board from an audit of an
assessee's books of account or other papers that the property of the
assessee was incorrectly valued or misclassified for any cause, then
to the extent that this error caused the board to assess taxable
tangible property which should not have been assessed or to assess it
at a higher valuation than the board would have entered on the roll
if the error had not occurred, the roll may be corrected under this
article at any time within four years after the assessment was made
or within the period for which a waiver is given pursuant to Section
868.


4877.  If the correction will increase the amount of taxes due, the
board shall give the assessee opportunity for a hearing after at
least five days notice at which he may present his objections to the
change. The board's decision is final.



4878.  The date and nature of the correction shall be entered in the
records of the board.



4879.  The board shall transmit a statement of the correction of the
assessment to the auditor of the county or city in which the
property is located.


4880.  The auditor shall enter the correction on the roll of the
county or city opposite the description of property, and shall file
and preserve the statement of the correction as a public record. The
auditor shall make any necessary changes in his account with the tax
collector.
