(e) "Qualified owner" means a Cold War veteran, the spouse of a Cold War veteran, or the unremarried surviving spouse of a deceased Cold War veteran. Where property is owned by more than one qualified owner, the exemption to which each is entitled may be combined. Where a veteran is also the unremarried surviving spouse of a veteran, such person may also receive any exemption to which the deceased spouse was entitled.

(f) "Qualified residential real property" means property owned by a qualified owner which is used exclusively for residential purposes; provided, however, that in the event that any portion of such property is not used exclusively for residential purposes, but is used for other purposes, such portion shall be subject to taxation and only the remaining portion used exclusively for residential purposes shall be subject to the exemption provided by this section. Such property shall be the primary residence of the Cold War veteran or the unremarried surviving spouse of a Cold War veteran, unless the Cold War veteran or unremarried surviving spouse is absent from the property due to medical reasons or institutionalization.

(g) "Latest state equalization rate" means the latest final state equalization rate or special equalization rate established by the commissioner pursuant to article twelve of this chapter. The commissioner shall establish a special equalization rate if it finds that there has been a material change in the level of assessment since the establishment of the latest state equalization rate, but in no event shall such special equalization rate exceed one hundred. In the event that the state equalization rate exceeds one hundred, then the state equalization rate shall be one hundred for the purposes of this section. Where a special equalization rate is established for purposes of this section, the assessor is directed and authorized to recompute the Cold War veterans exemption on the assessment roll by applying such special equalization rate instead of the latest state equalization rate applied in the previous year and to make the appropriate corrections on the assessment roll, notwithstanding the fact that such assessor may receive the special equalization rate after the completion, verification and filing of such final assessment roll. In the event that the assessor does not have custody of the roll when such recomputation is accomplished, the assessor shall certify such recomputation to the local officers having custody and control of such roll, and such local officers are hereby directed and authorized to enter the recomputed Cold War veterans exemption certified by the assessor on such roll.

(iii) The exemption provided by paragraph (a) of this subdivision shall be granted for a period of ten years. The commencement of such ten year period shall be governed pursuant to this subparagraph. Where a qualified owner owns qualifying residential real property on the effective date of the local law or resolution providing for such exemption, such ten year period shall be measured from the assessment roll prepared pursuant to the first taxable status date occurring on or after the effective date of the local law or resolution providing for such exemption. Where a qualified owner does not own qualifying residential real property on the effective date of the local law or resolution providing for such exemption, such ten year period shall be measured from the assessment roll prepared pursuant to the first taxable status date occurring at least sixty days after the date of purchase of qualifying residential real property; provided, however, that should the veteran apply for and be granted an exemption on the assessment roll prepared pursuant to a taxable status date occurring within sixty days after the date of purchase of residential real property, such ten year period shall be measured from the first assessment roll in which the exemption occurs. If, before the expiration of such ten year period, such exempt property is sold and replaced with other residential real property, such exemption may be granted pursuant to this subdivision for the unexpired portion of the ten year exemption period, provided however, that notwithstanding the ten year limitation imposed by the foregoing provisions of this subparagraph, a county, city, town, village or school district that has adopted a local law or resolution pursuant to paragraph (a) of this subdivision may adopt a local law or resolution providing that the exemption authorized by this section shall apply to qualifying owners of qualifying real property for as long as they remain qualifying owners, without regard to such ten year limitation. Each county, city, town or village may adopt a local law, and each school district may adopt a resolution, to reduce the maximum exemption allowable in paragraphs (a) and (b) of this subdivision to six thousand dollars, nine thousand dollars and thirty thousand dollars, respectively, or four thousand dollars, six thousand dollars and twenty thousand dollars, respectively.

The owner or owners shall file the completed form in the assessor's office on or before the first appropriate taxable status date. The exemption shall continue in full force and effect for all appropriate subsequent tax years and the owner or owners of the property shall not be required to refile each year. Applicants shall be required to refile on or before the appropriate taxable status date if the percentage of disability percentage increases or decreases or may refile if other changes have occurred which affect qualification for an increased or decreased amount of exemption. Any applicant convicted of willfully making any false statement in the application for such exemption shall be subject to the penalties prescribed in the penal law. 4. Notwithstanding the provisions of this section or any other provision of law, in a city having a population of one million or more, applications for the exemption authorized pursuant to this section shall be considered timely filed if they are filed on or before the fifteenth day of March of the appropriate year. 5. A local law or resolution adopted pursuant to this section may be repealed by the governing body of the applicable county, city, town, village, school district or, in the case of a city with a population of one million or more, the local legislative body. Such repeal shall occur at least ninety days prior to the taxable status date of such county, city, town, village, school district or legislative body. 6. Notwithstanding any other provision of law to the contrary, the provisions of this section shall apply to any real property held in trust solely for the benefit of a person or persons who would otherwise be eligible for a real property tax exemption, pursuant to this section, were such person or persons the owner or owners of such real property. 7. (a) For the purposes of this section, title to the portion of real property owned by a cooperative apartment corporation in which a tenant-stockholder of such corporation resides and which is represented by his or her share or shares of stock in such corporation as determined by its or their proportional relationship to the total outstanding stock of the corporation, including that owned by the corporation, shall be deemed to be vested in such tenant-stockholder.

(b) Provided that all other eligibility criteria of this section are met, that proportion of the assessment of such real property owned by a cooperative apartment corporation determined by the relationship of such real property vested in such tenant-stockholder to such real property owned by such cooperative apartment corporation in which such tenant-stockholder resides shall be subject to exemption from taxation pursuant to this section and any exemption so granted shall be credited by the appropriate taxing authority against the assessed valuation of such real property; the reduction in real property taxes realized thereby shall be credited by the cooperative apartment corporation against the amount of such taxes otherwise payable by or chargeable to such tenant-stockholder.
