New York statutory residency, explained
Not tax or legal advice. Verify with a qualified professional.
New York decides statutory residency on two limbs that must both hold: a day count, and a permanent place of abode. It is the most aggressively enforced residency test in the United States — the state runs a dedicated audit programme and routinely subpoenas mobile phone records, E-ZPass logs and credit card statements to reconstruct where someone actually was. This is a test where the quality of your evidence matters as much as the underlying facts.
US-NY · v2026.1
New York statutory residency
You are a New York statutory resident if you maintain a permanent place of abode in New York for substantially all of the year AND spend more than 183 days (i.e. 184+) in New York. ANY part of a day in New York counts as a New York day — a red-eye arrival at 00:10 counts here even when it fails the UK midnight test. Days in transit through NY airports between two non-NY points, and inpatient medical days, are excluded.
How days are counted
- Any part of a day present counts as a full day.
- Pure transit, without passing border control, is excluded.
The day count is stricter than you expect
Any part of a day physically present in New York counts as a full New York day. A red-eye landing just after midnight uses a day. A three-hour meeting uses a day. This is the opposite of the UK’s midnight rule, and people who move between the two systems reliably undercount here.
The exceptions are narrow. Travel purely in transit between two points outside New York — a connection at JFK between London and Toronto — does not count. Days spent as a hospital inpatient do not count. Almost everything else does.
The abode limb decides more cases than the count
A permanent place of abode is a dwelling you maintain that is suitable for year-round use. It does not need to be your home, you need not own it, and you need not sleep in it. Because the limb is about maintenance and suitability rather than use, it catches arrangements people assume are safe: a family apartment kept available, a property retained after a move.
The rule was tightened recently, which matters if you are relying on older guidance or a professional’s memory of it. Check the current New York State Department of Taxation and Finance position rather than assuming continuity, and treat this page as an orientation, not an answer.
US-NYC · v2026.1
New York City statutory residency
New York City levies its own resident income tax. You are an NYC statutory resident if you maintain a permanent place of abode in the five boroughs for substantially all of the year AND spend more than 183 days in the City. Any part of a day in NYC counts. Yonkers has an equivalent separate test.
How days are counted
- Any part of a day present counts as a full day.
- Pure transit, without passing border control, is excluded.
New York City runs the same test again
The City applies identical mechanics within the five boroughs: the day count plus an abode in the City. The two tests are independent. It is entirely possible to be a State statutory resident and not a City one, and the counters run separately over the same ledger. Yonkers operates its own equivalent.
The other bright-line states
New York is the most aggressively enforced of this family, but it is not alone in it. Four other states apply the same two-limb structure — a day count plus a permanent place of abode — and if you move within the north-east you are likely to meet another one rather than escape the pattern.
US-NJ · v2026.1
New Jersey statutory residency
N.J.S.A. 54A:1-2(m)(2): a non-domiciliary who maintains a permanent place of abode in New Jersey AND spends in the aggregate MORE than 183 days of the taxable year in New Jersey is a resident taxpayer — unless in the Armed Forces of the United States. A NJ domiciliary escapes residence only with no NJ abode, an abode elsewhere, and no more than 30 days in NJ. New Jersey publishes no rule for what counts as a day, so treat one-day margins as undecided.

How days are counted
New Jersey’s test needs more than 183 days in the state alongside an abode maintained there, with an exclusion for members of the armed forces. For anyone commuting across the Hudson this matters more than it first appears: the pattern that makes you a New York statutory resident is frequently the same pattern that makes you a New Jersey one, and the two states can reach the same year on different footings.
Connecticut and Massachusetts run the same shape, each needing more than 183 days plus an abode, and each with its own military exclusion. Pennsylvania applies the same day threshold and abode requirement without the military limb.
The practical consequence is that the record you need is not “days in New York” but days in every state you touch. A ledger built around one state’s threshold answers only that state’s question, and it is the second state’s enquiry that tends to arrive unprepared for.
What Residay computes and what it asks
The app derives the raw State and City day counts from your trips, projects the date each threshold would be crossed, and holds the evidence behind every attributed day. What it cannot see is the abode: whether a dwelling is maintained, and whether it is suitable for year-round living, are legal questions about arrangements, not about location. So the app asks — separately for the State and for the City, scoped to the tax year — and keeps each answer dated alongside the count.
Residay also tracks state-level presence for California, Florida, Nevada, Tennessee, Texas and Washington as advisory presence evidence. Those counters decide nothing on their own; they exist so that if a state ever asks where you were, your ledger already holds a dated answer.
Planning notes
- Both limbs must hold. If you can genuinely end the abode, the day count stops mattering — and that is usually the cleaner lever.
- Part-day counting makes airport and meeting choices material in a way annual planning does not capture. Track as you go; reconstructing a year afterwards is exactly what audits punish.
- Domicile is a separate route to residency and is not addressed by these counters. Moving away without changing domicile can leave you a resident regardless of days.
- Keep contemporaneous evidence. In an audit the burden is effectively yours, and a ledger built from records at the time is worth far more than a reconstruction built from memory.

Common questions
What makes someone a New York statutory resident?
Two things must both be true for the calendar year: you spent more than 183 days in New York State, and you maintained a permanent place of abode there for substantially all of the year. Failing either limb means statutory residency does not attach, though you may still be a resident by domicile.
Does a part day count as a New York day?
Yes. Any part of a day physically present in New York counts as a full day, including the day you arrive and the day you leave. The narrow exceptions are travel purely in transit between two points outside New York, and days as a hospital inpatient.
What counts as a permanent place of abode?
A dwelling maintained by you and suitable for year-round living, whether or not you own it. It does not have to be your home, and in some circumstances a property you keep for others can qualify. The rule was tightened recently, so the current Department of Taxation and Finance guidance is the reference that matters.
Which other states use a bright-line day test like New York's?
New Jersey, Connecticut, Massachusetts and Pennsylvania all apply the same two-limb structure: more than 183 days in the state plus a permanent place of abode there. The mechanics are close enough that a move within the north-east rarely escapes the pattern — it usually just changes which state is asking.
If I leave New York for New Jersey, am I in the clear?
Not automatically. New Jersey runs its own statutory residency test on the same shape as New York's, so a commuter pattern that made you a New York statutory resident can make you a New Jersey one instead. Worse, both states can reach the same year on different footings, which is why the day record has to cover every state you spend time in rather than just the one you left.
How does New York City residency differ from New York State?
The City applies the same two-limb mechanics one layer down: more than 183 days within the five boroughs plus a permanent place of abode in the City. You can be a State statutory resident without being a City one, and the two counts run independently over the same travel history.
