Authorizes a childhood education surcharge on the personal income tax for cities having a population of one million or more persons

This bill allows cities with over 1 million residents (like New York City) to add a 4.3% surcharge on personal income tax for residents earning over $500,000, effective January 2026. It applies to married couples filing jointly, single filers, heads of household, and estates/trusts. All revenue from this surcharge must be used exclusively for early childhood education programs in the city, not general funds. The surcharge expires December 2030, and cities must adopt the local law by December 2025.
