(Tax Law, section 208(10))
Example 1: A domestic corporation is incorporated in New York State on November 19, 2021. The corporation selects the fiscal-year basis of reporting and uses the date November 30th as the last day of its fiscal year. The corporation is subject to tax for the period November 19, 2021, to November 30, 2021, and must file a report for that period. The report must be filed on or before March 15, 2022.
Example 2: A foreign corporation, which reports for Federal income tax purposes on a fiscal-year basis, uses September 30th as the last day of its fiscal year. The corporation leases a store in New York City on March 1, 2021. The corporation continues to do business throughout the year 2021. Since the taxpayer reports for Federal income tax purposes on a fiscal-year basis, its first taxable year for purposes of article 9-A begins March 1, 2021, and its tax is computed on the basis of an accounting period that begins October 1, 2020, and ends September 30, 2021. The report must be filed on or before January 15, 2022.
