The New York 184-day rule: a survivor's guide
New York's 184-day + permanent place of abode rule is one of the most aggressively audited residency tests in the world. Here's how it works, what triggers an audit, and how to defend yourself.
New York runs the most aggressive residency-audit program in the country. In 2022–23, the state collected roughly $3 billion from residency audits alone. If you spend significant time in New York while claiming to be a resident of a no-tax state — Florida, Texas, Tennessee — you are a target.
The 184-day rule, in plain English
Under New York Tax Law § 605(b)(1)(B), you are a 'statutory resident' of New York for a tax year if both of these are true:
- You maintain a permanent place of abode in New York for substantially all of the year (more than 11 months).
- You spend more than 183 days of the year in New York — i.e., 184 or more.
Note the threshold is more than 183, so 183 days is fine; 184 is not. Hence the name 'the 184-day rule.'
What counts as a day in New York?
Almost everything. Any part of a day spent in New York counts as a full day — including time in JFK, LGA, EWR, or even a 30-minute layover at Penn Station.
- Counts: any presence at all, even a few minutes.
- Exceptions: travel days where you only changed planes (not boarding/disembarking on a NY-origin or NY-destination flight); days you were in NY solely as a hospital patient; days as a member of the U.S. armed forces in NY for active duty.
- Surprising: a Sunday brunch in Manhattan is a 'day' in New York for residency purposes.
What is a 'permanent place of abode'?
This is the part that catches people. A permanent place of abode (PPA) is a dwelling place permanently maintained by you, suitable for year-round use. You don't have to own it. You don't have to live there. You don't even need to use it.
- An apartment you rent year-round in NYC, even if you never sleep there: PPA.
- A house you own in the Hamptons that's habitable in winter: PPA.
- A summer-only beach house with no winter heat: not a PPA (winter access matters).
- A bedroom in a parent's apartment that's available to you: probably a PPA, depending on facts.
The Court of Appeals weakened this rule in Matter of Gaied (2014): the abode must be one you 'actually used as a residence' to qualify. But the burden of proof is on you, and 'I never sleep there' is not a great defense by itself.
How a New York residency audit actually works
If you file a non-resident or part-year return and the state has reason to believe you spent more than 183 days in New York, you'll get a residency questionnaire. They will ask for:
- Cell phone records (location data and call towers).
- EZ-Pass and toll records.
- Credit card and bank statements (where were you swiping?).
- Calendar entries and travel itineraries.
- Boarding passes, hotel receipts, train tickets.
- Any evidence of physical presence — gym check-ins, doctor visits, even social media posts with geolocation.
Auditors will reconstruct your year day-by-day. They will catch every day you spent in New York. If you don't have a contemporaneous record showing where you were, the auditor's reconstruction wins.
How to defend yourself
There is exactly one rule: keep a contemporaneous day-by-day log of where you were. Every day of the year. Don't reconstruct it after the fact — auditors can tell.
Tax Days is built for exactly this. Log your trips as you go. The app tracks your day count against the New York 184-day rule in real time, warns you before you cross, and exports an audit-ready PDF if your accountant asks. See pricing.
If you split time between New York and Florida, your goal is 183 or fewer days in NY. Tax Days will tell you the exact date you'd hit 184 if you stay — so you can leave 24 hours earlier and keep your domicile claim.
