New York City taxes its residents on top of New York State. Besides people domiciled in the City, it taxes a statutory resident: someone who keeps a permanent place of abode in the City and spends more than 183 days of the tax year there (NYC Administrative Code 11-1705). The count is days inside the five boroughs, not days anywhere in the State, which is why a person with a City apartment and a Hudson Valley house can be a State statutory resident without being a City one.
Each person is a New Jersey resident who keeps a Manhattan apartment, tax year 2025, counting the arrival and departure day. Add NYC to a stay line (for example 2025-01-01 to 2025-07-02 NYC) and the counter shows a New York City row beside the New York one.
| City stays | NYC days | Against the 183-day limit |
|---|---|---|
| 1 January to 2 July | 183 | No room left |
| 1 January to 3 July | 184 | Over by 1 |
| 1 May to 31 October | 184 | Over by 1 |
Every City day is also a State day, so the same stays count toward New York State’s own 183-day test, with its own abode condition. Days at a Westchester or Long Island house count toward the State total but not the City total.
New York City income tax applies to City residents. Besides people domiciled in the City, a statutory resident is someone who keeps a permanent place of abode in the City and spends more than 183 days of the tax year in the City (NYC Administrative Code 11-1705, the same shape as the State test). So 183 days inside the five boroughs is the most you can spend and stay under the line; the 184th crosses it. Domicile is separate, and days do not matter if the City is your permanent home. Check the Department of Finance's own guidance.
The wording is parallel, but they are measured separately. The State test counts days anywhere in New York State; the City test counts only days inside the five boroughs. You can be a statutory resident of the State (say, 200 days split between a Hudson Valley house and the City) without being a City resident, and each test needs its own abode. The counter tracks both: add NYC to a stay line for days in the five boroughs and the City is counted on top of the State.
The counter defaults to counting any part of a day, so both the arrival day and the departure day count, which is the conservative reading New York usually takes. Counting nights only drops the departure day.
Not by itself. The abode has to be a permanent place you keep and can use, and you also have to spend more than 183 days in the City. With fewer days the statutory test does not apply, although domicile can still make you a resident. The counter only does the day arithmetic.
