(Tax Law, section 208(10))
The calendar-year taxpayer's first accounting period and its first taxable year ends on December 31, 2021 in each of the following examples. The taxpayer's first report must be filed on or before April 15, 2022.
Example 1: The corporation is organized in New York State on October 22, 2021, and its certificate of incorporation is filed in the Office of the Secretary of State on the same date. The corporation becomes subject to tax on October 22, 2021, and its first accounting period and taxable year begins on that date irrespective of when the corporation starts to transact business.
Example 2: The corporation is organized in New York State on December 31, 2021, and its certificate of incorporation is filed in the Office of the Secretary of State on the same day. The corporation's first accounting period and taxable year is one day, December 31, 2021, and the corporation must file a report based on such period.
Example 3: The foreign corporation, which reports for Federal income tax purposes on a calendar-year basis, leases space for an office in New York City on February 5, 2021. Prior to February 5, 2021, the corporation did not do business, employ capital, own or lease property, maintain an office, or derive receipts from activity in New York State. The corporation hires personnel and opens its office in New York City on March 1, 2021. The corporation becomes subject to tax on February 5, 2021. Since the taxpayer reports for Federal income tax purposes on a calendar-year basis, its first taxable year for purposes of article 9-A begins February 5, 2021, and its tax is computed on the basis of an accounting period that begins January 1, 2021, and ends December 31, 2021.
