The New York State fiscal year begins April 1st and ends March 31st of the following calendar year. Each institution subject to assessment pursuant to this Part is billed five times for a fiscal year: four quarterly assessments (each approximately 25 percent of the anticipated annual amount) based on the banking division's estimated annual budget at the time of the billing, and a final assessment (or "true-up"), based on the banking division's actual expenses for the fiscal year. Any institution that is a regulated entity for any part of a quarter shall be assessed for the full quarter.
