A.
In the event that the total assessed value of any real property for which an exemption prescribed in Subdivision 1 or 2 of § 458 of the Real Property Tax Law has been granted increases or decreases as the result of a revaluation or update of assessments, and a material change in level of assessment, as provided in Title 2 of Article 12 of the Real Property Tax Law, is certified for the assessment roll pursuant to the rules of the State Board of Equalization and Assessment, the City of Schenectady Assessor shall increase or decrease the amount of such exemption by multiplying the amount of such exemption by such change in level of assessment. If the Assessor receives the certification after the completion, verification and filing of the final assessment roll, the Assessor shall certify the amount of exemption as recomputed pursuant to this subsection to the local officers having custody and control of the roll, and such local officers are hereby directed and authorized to enter the recomputed exemption certified by the Assessor on the roll.
B.
Owners of property who previously received an exemption pursuant to § 458 of the Real Property Tax Law, but who opted instead to receive exemption pursuant to § 458-a of the Real Property Tax Law, may again receive an exemption pursuant to § 458 of the Real Property Tax Law upon application by the owner within one year of the adoption of this article. The Assessor shall recompute all exemptions granted pursuant to § 458 of the Real Property Tax Law by multiplying the amount of each such exemption by the cumulative change in level of assessment certified by the State Board of Equalization and Assessment measured from the assessment roll immediately preceding the assessment roll on which exemptions were first granted pursuant to § 458-a of the Real Property Tax Law; provided, however, that if an exemption pursuant to § 458 of the Real Property Tax Law was initially granted to a parcel on a later assessment roll, the cumulative change in level factor to be used in recomputing that exemption shall be measured from the assessment roll immediately preceding the assessment roll on which that exemption was initially granted. No refunds or retroactive entitlements shall be granted.
C.
The provisions of this article shall be applied retroactively to an assessment roll prepared on the basis of a taxable status date on or after March 1, 1994.
