NYC's Additional 3.876% City Tax on Equity Income

New York State has one of the highest state income taxes in the country (top rate 10.9% in 2025). New York City stacks an additional city income tax on top, topping out at 3.876% for residents. For a senior IC in Manhattan with $2M of RSU vest income, the city tax alone adds $77,520 to the bill beyond state tax.

The NYC tax is imposed on city residents only. A commuter from New Jersey or Connecticut pays state tax to New York but not NYC tax. A resident of Brooklyn or Manhattan pays both.

For equity-heavy earners, this means the difference between “New York” and “New York City” residency is 3.876% of ordinary income.

NYC tax mechanics

NYC residents file Form IT-201 (the New York state return) with Form IT-360.1 for the NYC portion. The NYC tax schedule (2025, married filing jointly):

• 0% to $21,600: 3.078%
• $21,600-$45,000: 3.762%
• $45,000-$90,000: 3.819%
• $90,000+: 3.876%

For any senior IC earning over $90K, essentially all city income is taxed at 3.876%.

Combined marginal rates

A senior IC living in Manhattan with $600K of taxable income faces:

• Federal top marginal: 37% (above $609K single)
• NYS top marginal: 10.9% (above $25M; lower brackets apply at this income)
• NYC marginal: 3.876%
• FICA and additional Medicare: 2.35%

Combined marginal on ordinary income: roughly 50%+ at top federal bracket. For RSU income at these levels, nearly half of each dollar vested goes to taxes.

For capital gains, the treatment is slightly better federally (23.8% including NIIT) but full at state and city rate: 20% + 3.8% + 10.9% + 3.876% = 38.58%.

Residency definition

NYC residency follows New York State rules under Tax Law §605 plus specific NYC rules under Admin. Code §11-1705. Two tests:

Domicile test. NYC is your domicile.

Statutory residency. You maintain a “permanent place of abode” in NYC AND spend 184+ days in NYC during the tax year. This is a significant trap for commuters who keep a city pied-à-terre.

The 184-day test is strict. A Connecticut resident with a Manhattan apartment who stays in it for 185 days becomes a NYC statutory resident, subject to city tax on all income, even income earned outside the city.

Commuter vs resident

A commuter to NYC from NJ or CT pays:

• NY State tax on NY-source income (wages while working in NY)
• No NYC tax
• Home state tax on everything (with credit for NY state tax paid)

A resident of NYC pays:

• NY State tax on all income
• NYC tax on all income
• Any trailing nexus from former states

For an equity-heavy earner considering NJ vs Manhattan, the savings of commuting are meaningful:

• Manhattan resident at $800K income: $31,000 NYC tax
• Commuter from NJ: $0 NYC tax, but NJ state tax on home-state income

The calculation includes cost-of-living differences, commute time, and quality-of-life factors beyond just tax.

Double-residency traps

A NYC resident who moves to Miami in July faces:

• NYS part-year return (IT-203) for January-June
• NYC part-year return for same period
• Florida has no state tax

But if they maintain a NYC apartment and spend 183+ days in NYC that year (including days before the move), they may be considered a full-year NYC statutory resident.

The 184-day trap is a trap: moving in early July but visiting NYC for 30 days August-December puts the day count at 185, triggering full-year NYC residency and full-year tax on all income.

Like California’s trailing nexus

New York has its own trailing-nexus rules for equity compensation. Grants made during NYC residency that vest post-move retain some NYC sourcing based on workday allocation.

New York uses the “convenience of the employer” rule for telecommuting, which is stricter than California’s pure workday rule. A NYC-employed worker who works remotely from elsewhere may still be considered NY-source for days worked remotely if the remote work is for the employee’s convenience (not the employer’s requirement).

Post-pandemic, the convenience rule has been challenged but not struck down. NY continues to claim source on remote workdays for most NY-employed workers who moved out of state.

Estate tax considerations

NYC residents face NY state estate tax (top rate 16% above $7.1M exemption in 2025) but no separate NYC estate tax. The state estate tax applies in Manhattan, Albany, and every NY locale in between.

For wealthy NYC residents considering pre-death moves to no-tax states, the exemption cliff is sharp: gross estate above $7.1M loses most of the exemption (“cliff effect”), and estates just above the exemption can pay disproportionately high state estate tax.

Moves worth considering

For NYC residents with large equity compensation:

Move to Westchester or Long Island. NY state tax still applies (10.9% top) but no NYC tax. Commute is feasible for most office-based jobs. Saves 3.876% on city-ceased income.

Move to NJ or CT. Lower state tax than NY (NJ top 10.75%, CT top 6.99%). Commute for in-office work. Significant savings versus NYC residency but some complexity with home-state vs NY-state taxation.

Move to Florida or Texas. No state tax, no city tax. Full relocation required. Potential post-move trailing nexus on NY-source equity compensation.

Each path has trade-offs. The cleanest tax outcome is no-tax state with complete severance from NY, but that requires leaving the NY job or making it fully remote.

Frequently asked

Do I pay NYC tax on capital gains from stock I bought before moving to NYC? If NYC is your residence at sale, capital gains are generally NYC-sourced. The basis and original purchase state don’t matter for gain sourcing.

What about interest and dividend income? Full NYC tax for residents. No preferential treatment for passive income.

Can I avoid NYC tax by incorporating? Limited. Using an LLC or S-corp doesn’t shield wages from NYC tax if you’re an NYC resident performing services. You’re still taxed on distributions as a resident.

Does §6501 statute apply to NYS/NYC audits? NY’s assessment period is 3 years for most returns, 6 years for substantial omission. Longer than federal §6501 in the 6-year case.

How does trailing nexus compare between NY and California? NY uses “convenience of the employer” rule which taxes remote workdays that are for employee convenience. California uses straight workday allocation. NY is generally stricter for remote workers.
