The short answer: New York taxes you as a resident if you are domiciled there, or if you meet the statutory residency test. That test has two parts, and both must be true: you maintained a permanent place of abode in New York for substantially all of the year, and you spent more than 183 days (so 184+) in the state. Meet both and New York taxes your worldwide income, regardless of where your real home is.
Statutory residency is the rule that catches people who think they have left. A New York City professional buys a home in Florida, files a Declaration of Domicile, changes the license, and considers the job done. But they keep the Manhattan apartment for work, and they are in the city 190 days a year for that job. New York does not care that Florida is now home. Two boxes are checked, abode plus days, and they owe New York resident tax on everything.
The two-part test
Both conditions have to be met in the same tax year. Fail either one and the statutory residency test does not apply to you.
1. A permanent place of abode, for substantially all of the year
A permanent place of abode is a residence suitable for year-round living that you maintain, whether you own it or rent it. “Substantially all of the year” has been interpreted, since tax year 2022, as more than 10 months. A place used only for vacations and not suitable for year-round use generally does not count. The abode does not have to be where you actually stay on a given day; maintaining it is what matters.
2. More than 183 days in New York
The day count is the second gate. Spend 184 or more days in New York while maintaining that abode and you are a statutory resident. Spend 183 or fewer and you are not, on this test.
People call it the “183-day rule,” but the statute says more than 183 days. Exactly 183 days keeps you out. 184 is the number that triggers residency. Plan against 183 as your ceiling, not 184.
How New York counts a day
This is where careful people still get caught. Any part of a day spent in New York counts as a full day. Land at JFK at 11:30 p.m. and that is a New York day. A lunch meeting in Manhattan on your way elsewhere is a New York day. There are narrow exceptions, such as merely passing through, or certain days spent solely for medical treatment, but the default is that presence for any part of the day counts.
And the days accumulate across the whole year, not just one stretch. Every weekend visit, every business day, every family event adds to the same total. Because the burden of proof in an audit is on you to show the days you were not in New York, an unproven day is effectively counted against you.
Know your New York day count before December, not after the audit.
DayStayed counts your New York days automatically and warns you as you approach 183, so you can change plans while it still matters.
Statutory residency vs. domicile
These are two separate ways New York can claim you, and it is worth keeping them straight.
- Domicile is your one true, fixed, permanent home, the place you intend to return to. Changing it requires both intent and action, and New York auditors weigh a well-known set of factors: your home, your active business ties, the time you spend, your near-and-dear items, and your family.
- Statutory residency ignores intent entirely. It is a mechanical, two-part test: abode plus 184 days. You can genuinely be domiciled in Florida and still be a New York statutory resident.
Someone who has cleanly changed domicile to Florida can still walk straight into statutory residency by keeping a New York apartment and spending too many days in the state. The day count is the part you control most directly, and it is the part a good log defends.
How audits are won
New York runs one of the most aggressive residency audit programs in the country, and it targets high earners who claim non-residency. The examiners want proof, day by day. The strongest defense is a contemporaneous record: a log of where you were each day, kept as the year happened, supported by evidence that stands up to scrutiny:
- Cell phone location data and records.
- Credit and debit card transactions with locations and dates.
- E-ZPass and toll records.
- Travel itineraries and boarding passes.
- Building key-fob and swipe records where available.
Auditors are trained to distrust a calendar assembled after the notice arrives. A timestamped daily log built through the year, corroborated by these sources, is what wins. That is the entire case for tracking every day rather than reconstructing later.
Domiciled out of state, but keeping a New York City apartment year-round and commuting in for work. That is abode plus a high day count, the exact fact pattern statutory residency was written to catch. If this is you, the day count is not optional to track.
