made to such current base proportions made pursuant to paragraph (c)
hereof no later than thirty days subsequent to the date on which the

2. For the purposes of this section, the base percentage and the
current percentage of each class and for each portion shall be computed
pursuant to this subdivision.
(a) Base percentage. The base percentage for each class for each
assessing unit and portion thereof shall be determined as follows:
(1) Determine the estimated market value of each class by dividing the
taxable assessed value of the real property in each class in the special
assessing unit and portion thereof appearing on the final assessment
roll completed and filed in nineteen hundred eighty-nine by the class
equalization rate which was finally adopted by the commissioner for such
roll.
(2) Adjust the estimated market value of each class to reflect any
change in the class designation of any parcel of real property.
(3) Determine the total estimated market value of the special
assessing unit or portion thereof by summing the estimated market value
of each class.
(4) Divide the estimated market value for each class by the total
estimated market value of the special assessing unit or portion thereof.
Such quotient, as expressed as a percentage to at least four places to
the right of the decimal point, shall be the base percentage of each
class for such special assessing unit or portion thereof.
(b) Current percentage. The current percentage for each class for each
assessing unit and portion thereof shall be determined as follows:
(1) Determine the estimated market value of each class by dividing the
taxable assessed value of the real property in each class in the special
assessing unit and portion thereof appearing on the latest final
assessment roll for which class equalization rates have been finally
adopted by the commissioner by the class equalization rate which was
finally adopted by the commissioner.
(2) Determine the total estimated market value of the special
assessing unit or portion thereof by summing the estimated market value
of each class.
(3) Divide the estimated market value for each class by the total
estimated market value of the special assessing unit or portion thereof.
Such quotient, as expressed as a percentage to at least four places to
the right of the decimal point, shall be the current percentage of each
class for such special assessing unit or portion thereof.
3. Where there was no taxable real property in a class in a portion on
the final assessment roll completed and filed in nineteen hundred
eighty-nine, the local base proportion, base percentages and current
percentages for such portion shall be determined as provided by this
subdivision for each tax levy based upon an assessment roll filed
subsequent to the assessment roll on which such property first appears.
(a) The local base proportions shall be the adjusted proportions or
adjusted base proportions, whichever are appropriate, determined
pursuant to this section for the assessment roll on which such property
first appears.
(b) The base percentage for each class shall be determined as follows:
(1) For each class other than the class appearing for the first time,
determine the estimated market value by dividing the taxable assessed
value of the real property in the class in the portion on the final
assessment roll on which the new class first appeared by the class
equalization rate determined for such class in such portion on such
roll.
(2) For the class appearing for the first time, determine the
estimated market value of such class by dividing the taxable assessed
value of the real property in such class on the final assessment roll on
which such class first appeared by the class equalization rate
determined for such class in the special assessing unit on such final
assessment roll.
(3) Determine the total estimated market value of the portion by
summing the estimated market value of each class.
(4) Divide the estimated market value for each class by the total
estimated market value of the portion. Such quotient, as expressed as a
percentage to at least four places to the right of the decimal point,
shall be the base percentage of each class for such portion.
(c) Current percentages shall be determined as otherwise provided by
this section, except that until the commissioner can determine a class
equalization rate for the new class in such portion, the class
equalization rate for the class in the special assessing unit shall be
used in lieu thereof.
4. Where there is a new portion that did not appear on the final
assessment roll completed and filed in nineteen hundred eighty-nine, the
local base proportion, base percentages and current percentages for each
class in such portion shall be determined as provided in subdivision
three of this section for a new class in a portion.
5. Adjusted base proportions. No later than five days subsequent to
the filing of the final assessment roll, the legislative body of each
special assessing unit shall adjust such current base proportions to
reflect the addition to the assessment roll of new property, additions
to or improvements of existing property or formerly exempt property or
the full or partial removal from the assessment roll of property by
reason of fire, demolition, destruction or new exemption or any change
in the class designation of any parcel of real property subsequent to
the taxable status date of the latest final assessment roll for which
class equalization rates have been finally adopted. The current base
proportions so adjusted shall be known as the adjusted base proportions.
6. Upon determination of the adjusted base proportions, the
legislative body of the special assessing unit shall certify within five
days to the commissioner, on forms prescribed by the commissioner, the
adjusted base proportions as computed pursuant to subdivision five of
this section for each class applicable to the special assessing unit and
each portion contained therein; the assessed value of all property in
each class for the special assessing unit and each portion contained
therein; the net change in assessed value for each class on the
assessment roll resulting from the additions to or removals from the
assessment roll referred to in subdivision five of this section for the
special assessing unit and each portion contained therein; and the net
change in assessed value for each class on the assessment roll resulting
from changes other than those referred to in subdivision five of this
section for the special assessing unit and each portion therein.
7. If subsequent to and within sixty days after the certification of
the adjusted base proportions as final by the legislative body of the
special assessing unit, should said legislative body discover that a
mathematical error was made in the determination of the adjusted base
proportions, the legislative body of the special assessing unit which
has made such error shall redetermine such adjusted base proportions,
subject to the procedures set forth in this section for the review and
certification of adjusted base proportions, prior to the levy of taxes
for that fiscal year. If the redetermination cannot be made prior to the
extension of taxes for that fiscal year, the tax levying body shall
adjust the tax levy for the ensuing fiscal year to account for the
improper apportionment of taxes which resulted from the error in the
determination of the adjusted base proportions.
8. Notwithstanding any other provision of this article, the
calculations required by this section shall not apply to town or county
special districts or zones of assessment.
