What a taxable index-fund account is actually worth after expense-ratio drag and after New York takes its share of the gain — which, in most states, is not at the federal preferential rate.

New York taxes your gains as ordinary income

There is no state equivalent of the federal preferential rate here — a long-term gain is charged at New York's normal income brackets, exactly like wages. This is the common case, and it surprises people who assume the federal 15% carries over. Long-term capital gains are taxed as ordinary income at the full graduated schedule above, topping out at 10.9%. New York taxable income starts from federal AGI, which already includes net capital gain, and the Tax Law provides no preferential rate, no holding-period discount, and no general exclusion — the federal preferential long-term rate does NOT carry over. A New York City resident adds the city tax on top, so a large long-term gain realized by an NYC resident can face a combined state-plus-city marginal rate above 14%, which is among the highest in the country and is the number that matters when comparing New York against a no-income-tax state for a liquidity event.
