How it works

Note: New York supplemental withholding rate is 11.7% for high earners (NYS Pub NYS-50). NYC residents pay an additional NYC personal income tax of up to ~3.876% on top of state.

RSU vests

RSU vests are W-2 supplemental wages in New York, withheld at the state supplemental rate (10.23%). Reconciled at filing against your actual marginal rate — same shortfall mechanics as federal.

ESPP qualifying dispositions

New York taxes both the ordinary-income piece (the §423(c) discount) and the long-term capital gain at ordinary rates. Federal qualifying-disposition rules still split the gain into ordinary income and LTCG; state treatment is layered on top.

ISO exercises

New York does NOT have a personal AMT for ISO exercises. Bargain element is not taxed at the state level on exercise (assuming you don't disqualify-sell). On a qualifying sale, the long-term gain is taxed at ordinary rates.

Frequently asked questions

What supplemental withholding rate does New York use for RSUs and bonuses?

Does New York have a state AMT for ISO exercises?

Where is this information sourced?

Top marginal rates are from the Tax Foundation 2025 state individual income tax brackets summary. State supplemental rates are from the published guidance of each state's revenue department (linked above). Personal AMT status reflects 2025 legislation. Always confirm current-year rules with the New York State Department of Taxation and Finance before making decisions.
