N.Y. Tax Law § 43
A limited liability company that has a single member and is disregarded as an entity separate from its owner for federal income tax purposes (without reference to any special rules related to the imposition of certain federal taxes, including but not limited to certain employment and excise taxes) shall be disregarded as an entity separate from its owner for purposes of determining whether or not the taxpayer that is the single member of such limited liability company satisfies the requirements to be eligible for any tax credit allowed under article nine, nine-A, twenty-two or thirty-three of this chapter or allowed under article thirty-two of this chapter prior to the repeal of such article. Such requirements, including but not limited to any necessary certification, employment or investment thresholds, payment obligations, and any time period for eligibility, shall be imposed on the taxpayer and the determination of whether or not such requirements have been satisfied and the computation of the credit shall be made by deeming such taxpayer and such limited liability company to be a single entity. If the taxpayer is the single member of more than one limited liability company that is disregarded as an entity separate from its owner, the determination of whether or not the requirements to be eligible for any tax credit allowed under article nine, nine-A, twenty-two or thirty-three of this chapter or allowed under article thirty-two of this chapter prior to the repeal of such article have been satisfied and the computation of the credit shall be made by deeming such taxpayer and such limited liability companies to be a single entity.
