Title 2 - Private Property
425-A - Abatement of County Taxes in Special Assessing Units.

(b) The general county tax extended on an eligible parcel shall be
abated by the abatement amount, which shall be calculated by multiplying
the taxable assessed valuation, after application of all exemptions for
which such parcel is eligible for general county tax purposes, by the
abatement tax rate determined pursuant to this subdivision, provided
that the abatement shall not exceed the general county tax otherwise
chargeable to such eligible parcel.
(c) The local legislative body shall determine separate abatement tax
rates for each class of property, each roll year and each portion of the
county for which a general county tax rate is determined. The abatement
rate shall be the base abatement tax rate calculated pursuant to this
subdivision multiplied by the abatement ratio.
(d) The abatement ratio shall be set forth in the local law, as it may
be amended from time to time, which adopts the abatement authorized by
this section. Such ratio shall be one-half if no other ratio is
specified in the local law. In no event shall the abatement ratio be
greater than one.
(e) For the general county tax levied on the assessment roll finally
completed in calendar year two thousand two, the base abatement tax rate
for a class shall be the general county tax rate for such class

applicable to such assessment roll, less the tax rate for such class for
the roll finally completed in calendar year two thousand one.
(f) In each subsequent year the base abatement tax rate shall be
adjusted to account for changes in the level of assessment by
multiplying the base abatement tax rate calculated pursuant to paragraph
(e) of this subdivision by the ratio between the class equalization rate
for such class for the roll completed in calendar year two thousand two
and the class equalization rate for such class for the assessment roll
for such subsequent year.
(g) If the equalized tax rate for a class in any year is less than the
equalized tax rate for the roll finally completed in calendar year two
thousand two but more than the rate for the roll completed in calendar
year two thousand one, the base abatement tax rate shall be recalculated
by dividing the difference between such equalized tax rates by the class
equalization ratio for the roll year of the taxes to be abated.
(h) If the equalized tax rate for a class and roll year after calendar
year two thousand two is less than the equalized tax rate for the roll
completed in calendar year two thousand one, no abatement shall be
granted for property in such class for such roll year.
(i) For purposes of this section, "class" shall have the meaning
provided by section eighteen hundred two of this chapter and "class
equalization rate" shall have the meaning provided by section twelve
hundred two of this chapter. The term "equalized tax rate" shall mean
the general county tax rate for a class and roll year multiplied by the
class equalization rate for such class and year.
5. Cooperative apartment corporations, trailers and mobile homes. The
abatement authorized by this section shall apply to taxes on real
property owned by a cooperative corporation and to trailers and mobile
homes to the extent such taxes are attributable to the property of
eligible shareholders or owners and shall be credited against the taxes
or rent otherwise payable by or chargeable to such eligible individuals
in the same manner as is provided for the exemption given by section
four hundred twenty-five of this title.
6. Retroactive implementation. A local law adopted pursuant to this
section may provide that benefits shall be given retroactively in
respect to all or specified assessment rolls finally completed in or
after the year two thousand two. Such local law may provide that the
assessor of such special assessing unit shall apply the retroactive
abatement as a credit against current taxes for one or more years or may
authorize the chief financial officer of the county to refund the excess
taxes collected without interest in one or more installments over a
period of one or more years.
