Outside its New York City and Monroe County rates, the model uses state defaults for district choices, with the minimum for mandatory differentials (5%, then 10% from April 1, 2025, under Social Services Law 410-x(10)) and zero for optional ones. The combined limit rises from 25% to 35% on December 24, 2025. Not modeled - the optional differentials for QUALITYstarsNY and the auto-injector initiative that OCFS added on December 24, 2025, Monroe County's 75% enhanced informal rate, and public assistance in countable income (omitted to avoid a circular dependency through the TANF dependent care deduction)
