Creates an enhanced real property tax circuit breaker credit

S 1147 creates a new tax credit for New York City residents (population over 1 million) who own or rent their primary home. The credit reduces state tax liability based on a portion of property taxes paid, after subtracting a threshold amount tied to household income. Eligibility requires living in the home for six+ months, meeting income limits, and filing state taxes. The credit applies only to property taxes on primary residences within NYC, with specific definitions for household income and tax calculations.
