Can I be a New York statutory resident even if I changed my domicile to Florida?

Yes. Statutory residency under New York Tax Law §605(b)(1)(B) is completely independent of domicile. If you maintain a permanent place of abode in New York for more than ten months and spend more than 183 days in the state, you are taxed as a full-year New York resident on your worldwide income regardless of where you are domiciled. Winning the domicile argument does not help if you fail the statutory residency test.

Does a day trip to New York count toward the 183 days?

Yes. Under 20 NYCRR 105.20, presence in New York for any part of a calendar day counts as a full day, so a lunch meeting, a late-night landing, or an afternoon in the city each count as one full day. Narrow exceptions exist for merely traveling through the state and for days you are confined by illness. Auditors reconstruct your days from cell-phone, E-ZPass, and credit card records, so keeping a contemporaneous log matters.

Is a New York vacation home a permanent place of abode?

Not automatically. In Matter of Obus (3d Dept. 2022) and Matter of Gaied, 22 N.Y.3d 592 (2014), the courts held that a dwelling is only a permanent place of abode if the taxpayer has a residential interest in it and actually uses it as a residence. A cottage suitable only for summer use, or a home used a few weeks a year with no personal effects left behind, generally does not count. A pied-à-terre you live in during the workweek clearly does.

Does keeping a Manhattan apartment also trigger New York City tax?

Yes. New York City applies the same statutory residency test as the state, so an apartment in the five boroughs plus more than 183 days makes you a New York City resident, adding the city income tax of up to 3.876% on your worldwide income. There is no New York City tax on nonresidents, so the city layer only appears once you become a statutory resident.

How many days can I safely spend in New York after moving away?

If you keep a permanent place of abode in New York, you must stay at 183 days or fewer to avoid statutory residency; 184 days makes you a full-year resident. Because any part of a day counts and the burden of proof is on you, most advisors recommend leaving a cushion and stopping well short of 183. If you have no New York abode, the day count alone does not make you a statutory resident.

The New York 183-Day Statutory Residency Test: Why a Manhattan Pied-à-Terre Taxes You After Moving to Florida.

By Ewan Morkel, EAJuly 1, 20267 min read

You can change your domicile to Florida, file the paperwork, and still owe New York tax on your worldwide income. Keep an apartment in Manhattan, cross 183 days, and the statutory residency rule makes you a full New York resident no matter where your home really is.

A hedge fund partner moves to Palm Beach, files a Florida declaration of domicile, changes his driver's license, and registers to vote in Florida. He is confident he has left New York. He also keeps the two-bedroom on the Upper East Side, because he still comes into the office most weeks and the kids visit. That last decision is the one that undoes the plan. The New York 183-day statutory residency test does not care where your true home is. If you keep a place to live in New York and spend more than 183 days in the state, New York taxes you as a full-year resident on your worldwide income, capital gains and all, even though your domicile is now in Florida.

The statute

Two ways to be a New York resident.

New York Tax Law §605(b)(1) defines a resident individual two separate ways, and people who move usually only defend against the first one. The first is domicile: your true, fixed, permanent home, the place you intend to return to. When you move to Florida and cut your ties, you are attacking domicile. The second definition, in §605(b)(1)(B) and its regulation at 20 NYCRR 105.20, is statutory residency, and it has nothing to do with intent. You are a statutory resident, taxed exactly like someone domiciled in New York, if you maintain a permanent place of abode in New York for substantially all of the taxable year and spend more than 183 days in the state. Both prongs have to be met, but neither one asks where you consider home to be. This is a purely mechanical test, and it is the one that catches movers who did everything else right.

The abode

A pied-à-terre is a permanent place of abode.

A permanent place of abode is a dwelling of a permanent nature that you maintain and that is suitable for year-round living. It does not have to be owned. A leased apartment counts, a spouse's apartment counts, and a Manhattan pied-à-terre absolutely counts. You maintain it for substantially all of the taxable year if you keep it for more than ten months, the threshold New York's audit guidelines adopted in 2022, down from the older eleven-month standard. A true vacation cottage that is only suitable for summers is not a permanent place of abode, and two court decisions have narrowed what the Department can count. In Matter of Gaied v. New York State Tax Appeals Tribunal, 22 N.Y.3d 592 (2014), the Court of Appeals held that the taxpayer must have a residential interest in the place, not merely own it. In Matter of Obus (3d Dept. 2022), a home the taxpayer used two or three weeks a year, with no personal effects left behind, was not a permanent place of abode despite his free and continuous access to it. A pied-à-terre you actually live in during the workweek is nothing like those cases. It is the textbook abode.

The day count

How the New York 183-day statutory residency test counts a day.

The 183-day prong is where the trap springs, because New York counts days more aggressively than people expect. Any part of a day spent in New York is a full New York day. Landing at LaGuardia at 11 p.m. is a day. A lunch in Midtown is a day. A layover where you leave the airport is a day. There are narrow exceptions for travel solely through the state and for days confined by illness, but the default is that presence for any fraction of a calendar day counts. Cross into day 184 and, with the abode already in place, you are a full-year resident. The difference between 183 days and 184 days is not one day of tax. It is tax on your entire worldwide income for the year. New York publishes detailed nonresident audit guidelines, and in a residency audit the Department will pull cell-phone records, E-ZPass logs, credit card statements, and building key-fob data to rebuild your calendar day by day. The burden of proving you stayed under the line is yours.

$3M stock sale: 183 days versus 184 days, 2026.

Long-term capital gain on stock sale: $3,000,000
New York tax as a Florida nonresident (intangible gain): $0
New York State tax as a statutory resident (9.65%): $289,500
New York City resident tax as a statutory resident (3.876%): $116,280
Total New York tax once you cross 183 days: $405,780
Cost of day 184 versus stopping at 183: $405,780

Illustrative, 2026 rates, married filing jointly, New York City resident. Assumes the $3M gain stacks on top of other income so it falls in the 9.65% New York State bracket (taxable income over $2,155,350); New York taxes capital gains as ordinary income. A New York nonresident owes no New York tax on gains from intangible property such as stock, so the entire liability turns on statutory residency, not on where the sale happened.

That table is the whole point. As a genuine Florida nonresident, New York cannot reach the gain on your stock, because a nonresident is taxed only on New York source income and intangible investment gains are not sourced to New York. Trip the statutory residency test and New York taxes you as if you never left, on every dollar of income from every source. The Palm Beach domicile you carefully built does not shield you, because statutory residency is an independent path to full residency that ignores domicile entirely. You can win the domicile argument and still lose the year.

The city layer

The New York City tax rides along.

New York City uses the same statutory residency test as the state, so a Manhattan apartment plus 184 days makes you a New York City resident too. That adds the city's personal income tax, up to 3.876% at the top, on your worldwide income, and there is no city tax on nonresidents at all. This is why the combined top marginal rate for a New York City resident, the state's 10.9% plus the city's 3.876%, reaches nearly 14.8%, the highest in the country. The pied-à-terre that felt like a minor convenience is the single fact that stacks a second tax on top of the first. If the apartment were in Westchester or Long Island instead of the five boroughs, you would face state statutory residency but not the city tax.

The defense

Breaking the test on purpose.

There are only two ways to defeat statutory residency, and they map to the two prongs. You can get rid of the New York abode, by selling or truly relinquishing the apartment so you do not maintain a permanent place of abode for more than ten months, or you can stay under 184 days and prove it. Most movers who want to keep a foothold in New York choose the day count, which means keeping a contemporaneous, defensible log all year, not reconstructing one after an audit notice arrives. Count conservatively, treat every partial day as a full day, and leave a margin, because auditors will. If you can, put the New York apartment in a form that is not yours to maintain, though be careful: a spouse's abode is attributed to you, and the Department reads maintenance broadly. Keep the day count and the abode question separate in your own head, the same way the statute does.

Statutory residency is a different fight from the domicile audits other high-tax states run, though the day-tracking discipline is identical. The mechanics resemble what California does under a different theory in the California FTB residency audit after a move to Texas, and the sourcing questions overlap with how California taxes RSUs after you move out of state. The lesson across all of them is the same: the move is not the paperwork, it is the calendar and the keys.
