If your home is in Nassau County or Suffolk County, you live on Long Island but you are not a New York City resident, and that is the distinction that matters for NYC resident vs. Long Island questions about taxes, voting, schools, and city programs. Brooklyn and Queens sit on the same landmass, but they are boroughs of New York City. Nassau and Suffolk are not. Everything below follows from that county line.
Where the City Ends on the Island
Long Island runs west to east across four counties: Kings (Brooklyn), Queens, Nassau, and Suffolk. The first two are inside New York City. The last two are not. In everyday speech, “Long Island” usually means Nassau and Suffolk, and nobody in Flatbush says they live on Long Island even though they technically do. When legal or tax definitions are at stake, the shorthand stops mattering. What matters is the county on your address.
The Income Tax Difference
New York City charges its own personal income tax on top of state tax. Rates run from roughly 3.078% to 3.876% depending on filing status and bracket. Nassau and Suffolk residents don’t pay it on their personal income. A person earning $100,000 in Garden City saves roughly $3,500 to $3,800 a year in city tax compared with the same earner across the border in Queens.
When the City Treats You as a Resident Anyway
New York City uses the same two-part residency test the state uses, applied to city boundaries. You are a city resident for tax purposes if either condition is met. Your domicile is inside the five boroughs, meaning the city is your permanent home and the place you intend to return to. Or, even without a city domicile, you keep a permanent place of abode in the city and spend more than 183 days of the tax year there, which makes you a statutory resident who owes city tax on worldwide income.1New York State Senate.

That second test catches Long Islanders who keep a weeknight apartment in Manhattan. Any part of a day spent in the city counts as a full day toward the 183.2New York State Department of Taxation and Finance. New York State Income Tax Definitions A permanent place of abode is broader than most people expect: any year-round-suitable dwelling you maintain, own, rent, or have ongoing access to, kept for more than 11 months of the year. A spouse’s leased studio counts. So does a household in the city where you can stay whenever you want and contribute money or services.3New York State Department of Taxation and Finance. Permanent Place of Abode If you keep any dwelling in the city while claiming nonresident status, the state expects you to keep records proving 183 days or fewer.
Commuting In From Nassau or Suffolk
If you live in Nassau or Suffolk and commute to a job in the city, you owe no New York City income tax on your wages. City income tax reaches residents, not people who work there.
One exception. If you are employed directly by the City of New York (the municipal government) and were hired on or after January 4, 1973, you must file Form NYC-1127. The form computes a payment equal to what you would owe as a city resident, which erases the tax advantage for city employees living outside the five boroughs.4NYC Department of Finance.

Voting
Only residents of the five boroughs vote in New York City elections, including mayor, city council, and borough president. To register you must be a U.S. citizen, at least 18 by Election Day, a city resident for at least 30 days before the election, and not claiming voting rights elsewhere.5NYC Board of Elections. Voter Qualifications Nassau and Suffolk residents vote in their own county, town, and village races along with state and federal contests, and have no vote in who runs New York City.
Public Schools
NYC public schools are reserved for city residents. A child living in Nassau or Suffolk cannot simply enroll. Families may request non-resident placement, but a school must first enroll every city resident, seats have to remain, and the family pays tuition. Non-resident students are also barred from specialized high schools, screened programs, gifted and talented programs, and pre-K, and get no city-provided transportation.6NYC Public Schools.

CUNY
The City University of New York treats residency differently at its two tiers. At senior colleges the question is state residency: 12 consecutive months in New York State qualifies you for the resident tuition rate. At community colleges there is an additional city-level rule, and you must have lived in New York City for at least the last six months before classes begin to get the in-city rate. Nassau and Suffolk residents can still attend a CUNY community college at the in-state rate, but they need a certificate of residence from their home county.7The City University of New York. IV.

City-Only Programs
Several New York City programs stop at the borough line. Fair Fares NYC, which cuts MetroCard fares in half for low-income riders, is open only to five-borough residents between 18 and 64 whose household income falls below set thresholds ($23,940 for a single person in 2026).8NYC.gov.

If a program is funded by city tax revenue and built for city residents, a mile east of the Queens-Nassau border puts it out of reach.
How To Confirm Which Side You’re On
Check your county. Kings and Queens are inside New York City. Nassau and Suffolk are not. Your county appears on your property tax bill, your driver’s license, and most official correspondence from local government. For tax residency questions involving the 183-day rule, permanent place of abode, or domicile, the New York State Department of Taxation and Finance publishes detailed guidance and accepts questions from taxpayers trying to work out where they file.2New York State Department of Taxation and Finance.
