What is the effective tax rate for millionaires living in NYC?
This fact-check may be outdated. Consider refreshing it to get the most current information.
Executive summary
A millionaire who lives in New York City faces a high combined tax burden made up of federal, New York State and New York City income taxes; the top non‑federal marginal rate for the very wealthy is roughly 14.8 percent (state plus city) and, when combined with the federal top marginal rate commonly used in recent analyses, produces a top marginal rate above 50 percent — but the actual effective tax rate that millionaires pay is substantially lower and varies widely depending on income composition, deductions and tax-law changes, with credible estimates clustering in the mid‑30s to low‑40s percent range [1] [2] [3].
1. What “effective tax rate” means in this context — marginal versus actual burdens
Marginal tax rates (the rate on the next dollar earned) differ from effective tax rates (total tax paid divided by total income), and New York’s system layers a progressive state schedule on top of a separate NYC local schedule, producing very high marginal rates at the top even though effective rates are lowered by deductions, preferential treatment of capital gains and other tax features [4] [2] [5].
2. The visible pieces: federal, state and city margins that create the headline numbers
State law established very high top brackets in recent years: New York State’s top rates include 10.3 percent for incomes above $5 million and 10.9 percent for incomes above $25 million, while New York City’s top local rate is about 3.876 percent for 2025 filings — together creating a non‑federal top marginal bite of roughly 14.8 percent [2] [4] [1]. Analysts commonly add the federal top marginal rate used in recent computations (37 percent in many official estimates) to produce a combined top marginal rate exceeding 50 percent before credits and other adjustments [2] [1].
3. Why headline marginal rates overstate what most millionaires actually pay
Many millionaires’ income is not all taxed at the top marginal rate: capital gains, pass-through preferences, business deductions, retirement and charitable strategies, and the phase‑in or phase‑out of credits alter effective tax bills; capital gains are notably concentrated among the wealthy and can be taxed differently than ordinary income, so a millionaire’s effective federal plus state plus city rate is often lower than the top marginal percentage [5] [6]. Tax preparers and local commentators estimate that for typical $1 million earners the combined effective rate can be “well above 40 percent” in some scenarios but will vary widely by source of income and deductions [3].
4. Recent policy changes and design choices that shift effective rates
Two policy dynamics matter: State and city top rates have been extended through 2032 for high earners, keeping non‑federal marginal rates high [2] [7], and federal changes — including the legacy effects of the 2017 TCJA and later Congressional actions — have altered top federal liability and deductions available to high incomes, producing both cuts and limits that move effective rates up or down depending on taxpayers’ circumstances [8] [9]. The SALT cap and potential changes to pass‑through entity taxation (PTET) are explicitly noted by local fiscal offices as important modifiers of the net‑of‑tax return for top filers [9].
5. Best synthesis from available reporting: a practical effective‑rate range
Given the range of published analyses and tax‑prep commentary, a plausible synthesis is that New York City millionaires face combined effective tax rates that typically fall in the mid‑30s to low‑40s percent of income in a representative year, while a small share of filers with mostly ordinary income taxed at the highest brackets could experience effective rates meaningfully higher and marginal top rates exceeding 50 percent when federal, state and city margins are stacked [3] [2] [1]. Reporting on tax shares also shows that millionaires pay a disproportionate share of New York’s income tax revenue — for example, millionaires accounted for roughly 41 percent of state personal income tax receipts in recent data — underscoring that, in aggregate, effective rates for the millionaire cohort are substantively high even if individual results vary [6] [10].
6. Caveats, competing narratives and political context
Advocates for higher taxes emphasize the progressivity and revenue yield of taxing millionaires who have paid rising shares of PIT revenue, while critics warn that marginal rate increases can prompt migration or income‑shifting; empirical studies cited by city fiscal analysts suggest migration effects exist but are usually small, concentrated to states like Florida, and can be offset by tax-code details such as SALT deductibility and PTET design [9] [10] [11]. Several independent local policy centers and commentators reach different normative conclusions — but they agree on the core factuality that marginal top rates in NYC are among the nation’s highest and that effective rates depend heavily on income composition and law specifics [1] [12].
