N.Y. Real Prop. Tax Law § 489-GGG
The tax exemption approved by the board shall continue in accordance with this title, provided that the applicant files an annual certificate of continuing use stating that the structure and property continue to be used for the industrial or commercial purposes justifying the issuance of the certificate of eligibility. The certificate of continuing use shall be filed with the tax commission on such form or forms and containing such information as shall be prescribed by the tax commission. The tax commission shall have authority to terminate a tax exemption on failure of an applicant to file an annual certificate of continuing use or on the recommendation of the finance commissioner who, in reviewing the certificate filed by an applicant, has determined that the structure or property has ceased to be used for the industrial or commercial purposes justifying the issuance of the certificate of eligibility.
