New York statutory residency: 184 days and a place to live

New York has a way of taxing people who don't live there. If your home is in New Jersey, Connecticut, Florida or abroad, New York can still tax you as a full resident — on all of your income, wherever you earned it — if two things are true in the same year. It is called statutory residency, and it catches people who never thought of themselves as New Yorkers.

The two conditions

If New York is not your domicile — the place you consider your permanent home — you are still a New York State resident for a tax year when you:

• maintain a permanent place of abode in New York for substantially all of the year, and

• spend 184 days or more in New York during the year.

Both, not either. Lots of days without a New York home doesn't make you a statutory resident (you may still owe New York tax as a nonresident on income from New York sources). A New York apartment with few days there doesn't either. It is the combination that does it — and then, as a resident, you pay state tax on all your income, not only what you earned in New York.

New York City uses the same test for its own income tax: a permanent place of abode in the city and 184 days or more in the city. Meet it and you are a city resident too.

It's 184, not 183

The rule is usually quoted as "183 days", and the statute does say "more than 183". What the Department of Taxation's own guidance spells out is the number that matters: 184 days or more. Day 183 is still fine; day 184 is the one that tips it. (We wrote about how often "183" means different things in different countries in the 183-day rule isn't one rule.)

What counts as a day

Any part of a day is a day. Arriving at 11 pm counts. A Saturday matinee counts. And you don't need to be at your New York home for the day to count — any presence anywhere in the state does.

There are only two exceptions in the state's audit guidelines:

• Travel. Presence solely to board a plane, ship, train or bus for a destination outside New York, or travel through the state that began outside it. Their own example: a Connecticut resident who drives to JFK to fly to Europe doesn't have a New York day. Buying a meal at the terminal doesn't change that; arriving a day early for a cruise to attend a business meeting does.

• In-patient medical stays. Days confined to a medical institution in New York don't count. Outpatient visits do.

What is a "permanent place of abode"

Broadly, a place where you can live that you permanently maintain and that is suitable for year-round use — whether you own it or not. It usually includes a place your spouse owns or leases. A cottage only suitable for summer holidays isn't one; neither is anything without the basics of a home, like a kitchen or a bathroom.

The courts have added one requirement: you need a residential interest in it — some basis to say you actually use it as a residence. The state's own example is a couple who live in New Jersey and keep a New York City apartment for evenings at cultural events rather than driving home. That apartment counts.

"Substantially all of the year" means more than 10 months

Since tax year 2022, the audit guidelines read "substantially all of the year" as generally more than 10 months (it used to be 11). This mostly matters in the year you take on or give up a New York home. The guidelines' example: someone who works in New York City all year but only starts renting an apartment there in March is generally not a statutory resident that year, even with more than 183 days.

It does not work the other way round: renting your New York house out for a few summer months doesn't stop it being your permanent place of abode, if it is otherwise yours to use.

A worked example

You live in Connecticut and keep a small apartment in Manhattan for the whole year. You are in the office four days a week, 48 weeks a year. That is 192 New York days from the office alone — eight past the line. You are a statutory resident of New York State and, because the apartment and the days are in the city, of New York City as well.

Cut it to three office days a week and you are at 144. That sounds safe, until you count the rest: a show on a Saturday, a dinner on a Sunday, a few extra days in the busy weeks. Forty more days of any kind and you are at 184. Flights out of JFK or LaGuardia don't add to it if you are only passing through to board.

The burden of proof is on you

This is the part people underestimate. If you maintain a New York home, you have to show that you spent fewer than 184 days in the state — New York doesn't have to show that you spent more. Its regulations require you to keep adequate records, and the standard of proof in an audit is "clear and convincing".

In practice, auditors test a diary or log against credit card receipts, phone records and similar evidence, and they generally accept credible, consistent accounts — weekends at home, for example — unless there is evidence of a different pattern. A day count you can't support is a day count you don't really have.

If New York is your home

Everything above is about people domiciled elsewhere. If New York is your domicile, you are a resident regardless of days, with two narrow exceptions. The simpler one: you kept no permanent place of abode in New York all year, kept one outside the state all year, and spent 30 days or less in New York. The other is built for long stays abroad: at least 450 days in a foreign country in a 548-day period, with strict limits on days in New York for you and your family.

How the app handles it

Track Country Days has New York as ready-made rules: New York State statutory residency, New York City statutory residency and the 30-day test for New Yorkers living elsewhere. The state rule counts every day you are in New York State in the calendar year, part days included, and flags day 184. The permanent place of abode is shown as a condition, because only you know whether you have one.

For New York City, the app tags your city days automatically when location tracking is on, using the city's official borough boundaries — so a day in Manhattan counts and a day in Westchester doesn't.

It can't tell which of your days were travel-only or spent in hospital, so its count can run high, never low. And because every day in the app has a dated history you can export as a PDF or CSV, it gives you the kind of record an audit asks for, kept as you go rather than rebuilt from receipts years later.

If you are not a U.S. citizen, the federal count is a different test entirely: see the substantial presence test, worked through with real dates.

As always: this is day tracking, not tax or legal advice. We count the days. Whether you are a New York resident for tax — and what follows if you are — is a question for a tax professional.
