How the tax works
Searches for an tax rate in New York usually mean you want one percentage to plan cash for a — but New York does not publish a separate equity rate. is taxed as ordinary wages under progressive NYS brackets, and NYC residents add a local income tax layer on the same wage income.
Federal progressive income tax and FICA apply on top of New York state and city tax.

NYC residents pay both NYS progressive tax and NYC local income tax on wages — a Manhattan tech worker with a large quarterly on high salary can hit top marginal brackets at both layers. Employees outside NYC pay NYS tax without the city layer. Yonkers and other local taxes may apply depending on residence.
New Jersey commuters are a distinct NY pattern. If you live in New Jersey and work in New York City, you may owe New York tax on wages earned in NYC while still owing New Jersey tax as a resident, with credit mechanics on the full return. The NJ–PA reciprocal agreement does not cover the NYC–NJ pairing — cross-Hudson equity comp is not the same as a simple single-state paycheck.
Moving from New York to Florida or Texas mid-year does not erase NY tax on vests that occurred while you were an NY resident. Part-year resident returns allocate income by residency period and sourcing rules. Estimated New York tax may be needed when state and city on a falls short of your actual liability after stacking salary and multiple vests.
