Applies to

Effect

Basis

NY Tax Law § 605(b)(1)(A)(i)

A New York domiciliary is taxed as a nonresident for a year in which they maintain no permanent place of abode in New York, maintain a permanent place of abode outside New York for the entire year, and spend 30 days or fewer in New York. All three conditions must hold for the whole taxable year; a 31st day, any New York abode, or a gap in your home elsewhere puts you back to being taxed as a resident on worldwide income.

Who it applies to

This matters most if you are:

• A New York domiciliary — someone whose legal, permanent home is still New York — who has actually set up a home in another state or country.
• A remote worker, retiree or executive who left New York but still returns for family, business or short visits.
• Someone who moved away but has not yet clearly changed domicile, and wants to be taxed as a nonresident meanwhile.

The Tax Department says the same tests apply to New York City and Yonkers residency, substituting the city for the state. If you are not a New York domiciliary, this rule is not the one that applies to you.

The rule — and why it exists

New York taxes a domiciliary as a resident unless they meet all three conditions of either Group A or Group B in Tax Law § 605(b)(1)(A) and 20 NYCRR § 105.20(b). Group A — the 30-day rule — requires that, for the taxable year:

1. 1you maintained no permanent place of abode in New York State during the year;
2. 2you maintained a permanent place of abode outside New York State during the entire year; and
3. 3you spent 30 days or less in New York State during the year (a part of a day is a day).

The burden is on you to show you met the conditions. Group B, the 548-day rule, is a separate test for people living abroad (see the FAQ above).

Why it exists: domicile is hard to shed, so a person can remain a New York domiciliary long after moving on. The rule gives genuinely departed domiciliaries an objective way to be taxed as nonresidents, while the two abode conditions stop someone from claiming it while keeping a base in New York or living nowhere in particular.

Counting the days

1. 1Count each day you are in New York during the taxable year (1 January to 31 December for calendar-year filers).
2. 2Any part of a day counts as a full day, so even a short visit uses one of your 30.
3. 3Presence solely to board a plane, ship, train or bus to a destination outside New York, or while traveling through New York to somewhere else, may be disregarded.
4. 4Thirty days or fewer, with both abode conditions met all year, keeps you a nonresident; day 31 ends it for that year.

Because the ceiling is low and auditors ask for proof, keep contemporaneous records of every New York day and of the days you spent elsewhere.

Examples

Example 1 — the rule holds

You sold your Westchester house, bought a home in Florida you live in all year, and stay in hotels when you visit New York — 22 days this year. No New York abode, a permanent abode elsewhere for the whole year, and fewer than 30 days: you are taxed as a New York nonresident even if New York is still technically your domicile.

Example 2 — lost on the 31st day

Same situation, but a busy autumn of client meetings pushes your New York days to 33. The day limit is breached, so the rule fails for the entire year and, as a domiciliary, you are taxed as a resident on your worldwide income.

Example 3 — the New York apartment defeats it

You spend only 18 days in New York, but you keep your Manhattan apartment furnished and available for your own use. Because you maintain a permanent place of abode in New York, the 30-day rule does not apply no matter how low your day count is.

Exceptions & edge cases

• The whole-year requirement. The conditions apply to the entire taxable year. Keeping a New York apartment for part of the year, or moving away mid-year, means the rule is not met for that year; the year of the move is normally a part-year resident year.
• The 548-day rule. Domiciliaries who spend at least 450 days abroad within 548 consecutive days, with no more than 90 New York days of their own in that period, no more than 90 New York days for their spouse (unless legally separated) and minor children wherever they stay in the state, and a prorated limit in the partial years at each end, are also treated as nonresidents. Full and part days count for both the foreign and New York totals.
• Travel days. Presence solely to board transport to a destination outside New York, or while traveling through the state, may be disregarded.
• Statutory residency is for non-domiciliaries. The separate 183-day statutory residency test applies to people domiciled elsewhere who keep a New York abode — a different rule from this one.

Common misconceptions

• "Under 30 days means I'm safe." Only if you also have no New York abode and a permanent abode elsewhere for the entire year.
• "A quick day trip doesn't count." Any part of a day counts as a full day, unless you were only passing through or heading to a departure point.
• "Leaving New York automatically changes my domicile." Domicile persists until you clearly establish a new one; until then, the 30-day or 548-day rule is what keeps you off the resident rolls.
• "If it applies, I owe New York nothing." You are still taxed as a nonresident on New York-source income.
