How does New York decide someone actually left?

The domicile track: leave and land, on paper

Domicile is a facts contest with a narrative problem. New York presumes an established domicile continues until a new one is established; the burden is on the person asserting the change (20 NYCRR 105.20(d)(2)), and the courts and the Department's own Nonresident Audit Guidelines require the change to be shown by clear and convincing evidence (Matter of Bodfish v. Gallman, 50 AD2d 457 (3d Dept 1976); Nonresident Audit Guidelines (Dec. 2021), p. 10). The examiner's working assumption, rarely stated but reliably present, is that no one leaves; the response's job is to tell a specific, documented story of someone who did. The story has two halves. The leaving half is the old life ending: the departure from the former home, school withdrawals (including small proofs such as a deposit forfeited at the old school), lease and membership terminations, the mail and designations swept to the new state. The landing half is the new life beginning, and the strongest records are full of paper nobody thinks of as tax evidence: the first correspondence with the real estate agent, dated before the move; the education consultant and the new school's application file; the transfer of medical and veterinary records to new providers; dues to local associations in the new community; any interim housing lease and its termination when the permanent home closed. Alongside the paper belongs the reasons memo, a short affirmative statement of why the family moved (family proximity, a child's school, aging parents, the location of the taxpayer's own history and institutions), because a move with articulable human reasons is easier to believe. A tax motive does not defeat a real move: the motives for a change of domicile are immaterial except as they indicate intention (Matter of Newcomb, 192 NY 238 (1908); Guidelines, p. 9), but a record that shows only the tax motive sends the examiner looking for the life that did not move. The memo is a declaration, and the regulation gives declarations due weight without letting them control over contrary conduct (20 NYCRR 105.20(d)(2)); the memo supports the binder, it does not substitute for it. Time and business involvement then do their work: the domicile case coexists with continued New York employment; people commute interstate constantly; but the calendar must show the center of life shifted even if the office did not, which is where this article's companion on wage allocation and the two-schedule day count carries half the load. The Guidelines themselves say that a suburban commuter's presence in New York for work, without more, does not create a New York domicile (Matter of Knight, DTA No. 819485, quoted at Guidelines pp. 20 to 21), and that retaining a New York residence is not, by itself, enough to negate a change of domicile; the auditor weighs whether the taxpayer is actively selling and what was moved out (Guidelines, p. 13). The counterexample is Matter of Silverman (DTA No. 802313), where a house that sat listed from 1975 to 1983 defeated the change because it was unclear how hard the taxpayers had tried to sell.

The statutory residency track, and the house that would not sell

The second track needs no intent at all: abode plus days equals resident. This is what makes New York the model of a statutory residency state: once the elements are met, the statute itself decides residency, with no closest-connections weighing to rebut it, in contrast to a presumptive residency state such as California, where day counts raise rebuttable presumptions and the record decides. The days element is arithmetic: any part of a day in New York counts, subject to the travel-through allowance in the regulation (20 NYCRR 105.20(c)), a rule the Appellate Division upheld as a reasonable elaboration of the statute in Matter of Leach v. Chu, 150 AD2d 842 (3d Dept 1989), and applied in Matter of Zanetti v. New York State Tax Appeals Tribunal, 128 AD3d 1131 (3d Dept 2015), where 167 full days and parts of 26 more at the taxpayer's New York home crossed the line; the Tribunal below had held that the travel exception does not reach trips whose origin or destination is the taxpayer's own New York home (DTA No. 824337). A commuting executive can cross 183 without noticing, which is why the presence schedule exists. The Department's Nonresident Audit Guidelines say the same, adding that a same-day arrival and departure still counts and that, while the literal rule could reach a taxpayer who steps over the state line for a second, no audit is expected to be built on presence that minimal (Guidelines, p. 53); the taxpayer should nonetheless plan on the literal rule, because the Guidelines describe the auditor's restraint, not a legal exception. The one exception beyond travel is medical: days confined to a New York medical institution do not count, under Stranahan and the Department's stated policy, but outpatient visits do (Guidelines, p. 54, citing Matter of Kern, 240 AD2d 969 (3d Dept 1997)).

The abode element is where the retained home lives, and it has four parts rather than the two it is usually given. Under 20 NYCRR 105.20(a)(2) and (e)(1), as read in Gaied and Obus, the dwelling must be permanent, meaning suitable for year-round use; it must be maintained by the taxpayer; the taxpayer must have a residential interest in it; and it must be maintained for substantially all of the taxable year, which the regulation glosses as generally the entire taxable year disregarding small portions of it. The Department administers that last phrase through a month-count convention in its Guidelines: before tax year 2022, a period exceeding eleven months, and beginning with tax year 2022, generally a period exceeding ten months, a convention the Audit Division applies in a year in which the taxpayer acquires or disposes of the residence, so an abode held for less than the count in that year does not produce a statutory resident no matter how the day count comes out (Guidelines, ch. VI, pt. D, pp. 49 to 50). The convention is neither a floor nor a ceiling. The Tax Appeals Tribunal has read the regulation's own text to reject ten months and a day: in Matter of Pilaro (DTA No. 829204, Aug. 18, 2022), an abode maintained from January 1 through November 1 fell short of substantially all of the year "under both the regulation's plain language and the Division's guidelines," so for 2022 and later years the ten-month convention is the Audit Division's opening position, not the end of the argument. In the other direction, the Guidelines call the rule general rather than absolute, cite an administrative law judge's holding that an apartment maintained ten and a half months was "substantial" under the old eleven-month rule (Matter of Brodman, DTA No. 818594), and warn that a home rented out for a few months each summer is still maintained for substantially all of the year because the rental did not occur in a year of acquisition or disposition (Guidelines, pp. 49 to 50). The duration element is the one most often dropped from the shorthand, and for a family that keeps a former residence and then sells or rents it, it is frequently the element that decides the year.

The move year is the year most exposed. Because the statute reaches a taxpayer "whether or not domiciled in this state for any portion of the taxable year," days in New York before the move count toward 183, and a family that leaves on July 1 after six months at home has about 181 New York days before it has done anything else (Guidelines, ch. VI, pt. E, p. 51, quoting Matter of Smith v. State Tax Commission, 68 AD2d 993 (3d Dept 1979), where a family that moved to Florida in July and could not sell the furnished house was taxed as a full-year statutory resident). The way out is abode duration and residential interest. If the house is emptied and staged on July 1 and the commuting spouse uses hotels, the residential interest arguably ends with the move, the abode is maintained about six months, and the year is a part-year year; the Department reached that result where a family moved every belonging out in mid-August and the house, still owned and listed, closed in November (TSB-A-97(3)I). If the commuting spouse sleeps at the house two nights a week, the residential interest runs all twelve months, and New York taxes the whole year, including everything earned after the move. The twist is that the same two nights a week cut the other way on the domicile track: the Guidelines treat a cross-border commuter's reduction to one or two nights a week at the old home as tending to confirm the stated intent to leave (Guidelines, p. 28). One fact feeds both tracks, pulling in opposite directions, and only the statutory track has a number in it.

The residential-interest element has its own history: for years the Department and the Tribunal read maintenance broadly enough that any kept residence, whatever its use, filled the element. The Court of Appeals fixed the frame in Gaied: a permanent place of abode requires a residential interest in the place, not bare ownership or maintenance. Obus applied that gloss to the vacation-home pattern and changed the working terms: maintaining a dwelling is not enough; the taxpayer must have utilized the dwelling as a residence, and a home the taxpayers owned but used at most a few weeks a year, over four hours from the office and never used to reach it, did not qualify. The court distinguished Matter of Evans, 199 AD2d 840 (3d Dept 1993), on exactly that access-to-work point, relied on the fact that the owners kept no personal effects in the house, and said in a footnote that 20 NYCRR 105.20(e)(1) cannot be read to dispense with the residential-interest requirement. For the relocated family whose former residence lingers unsold, Obus supplies the frame but not automatic safety. A retained home within the commuter's reach sits on the Evans side of the line, so the usage record carries the whole case: a house kept staged for sale, empty of the family's daily life, unused as a base for the commuting spouse's workdays, is a strong candidate for no residential interest, while the same house used as a crash pad on office nights is the Department's best exhibit. The facts to build are usage facts: where the commuting spouse stays on New York nights, the hotel folios that prove it, and, for a staged house, the record that the furniture is the stager's and the family's belongings left with the move. The cleanest structural exit is the one many such cases eventually reach anyway, although it does not operate the way it is usually described.

Renting the former residence to an unrelated third party on an arm's-length lease does not split the year; it decides it. The abode element is tested across the taxable year as a whole, so what the tenancy does is set the substantially-all count, and the date that matters is when the tenant takes possession and the owner gives up access, not when the lease is signed. A tenancy that begins in the middle of the year generally defeats the abode element for that entire year, not merely for the months after it begins, since the taxpayer then did not maintain the abode for substantially all of the year. For 2022 and later years, a tenant in possession by the end of October leaves the abode maintained ten months or less; a tenancy that starts in mid-November leaves about ten and a half months, which the Department will count under its convention and which Pilaro gives the taxpayer the text to contest; a tenancy that begins in mid-December does nothing for that year and its benefit falls in the following year instead. The Department's closest published authority treats a house still owned but emptied of belongings as no longer an abode maintained for substantially all of the year (TSB-A-97(3)I), and treats a three-month lease of the home to a charity as breaking the count while cautioning that a repeated arrangement might not (TSB-A-04(4)I, discussed at Guidelines p. 50). The timing matters only in a year the house carried a residential interest for part of the year, the move year or a crash-pad year; for a house that sat staged and unused all year, Obus may already defeat the abode element, and the lease date decides nothing for that year. The relinquishment also strips the taxpayer of any residential interest in the property, an application of the Gaied principle rather than a stated bright-line rule, and converts the property's story from ambivalence to investment. It should be documented with the same care as the move itself, including the framing that the rental followed a failed sale rather than a plan to keep a foothold, and it should be timed against the month count rather than signed whenever the broker happens to produce a tenant. Renting has a price of its own: rent from New York real property is New York-source income to a nonresident (Tax Law section 631(b)(1)(A)), so the family files a nonresident return every year of the tenancy; the eventual sale carries nonresident estimated tax at closing unless the house still qualifies as a principal residence under IRC section 121 (Tax Law section 663(c)(1)); and once the house stops being the principal residence, the federal exclusion of gain on its sale generally survives only if the sale closes within about three years of moving out, under the two-of-five-year test that New York follows (Guidelines, pp. 16 to 17). A family weighing a lease now against a price cut now should see both columns. A taxpayer whose retained home is in New York City faces a second, separate statutory test for city tax, a city abode plus more than 183 days in the city (N.Y.C. Admin. Code section 11-1705(b)(1)(B)); a Westchester house triggers only the state test.

Practice notes

The checklist for a move away from New York has five standing records: the move evidence binder, assembled at move time (agent correspondence, movers, schools, physicians, memberships, licenses, registrations); the reasons memo, written early and factually; the two day-count schedules shared with the allocation defense; and the retained-property record, which tracks the listing history and the showings and price reductions that prove active marketing (the Silverman problem), the renovation and market events that explain the delay, the usage record showing the family did not live there, what was moved out and when, the dates that fix how much of each year the property was maintained, and, when it comes, the lease and the tenant's possession date. Under audit, answer the document requests in the structure the two tracks demand, domicile facts and abode-and-days facts separately, because conceding confusion between them lets the examiner win the easier test with the harder test's facts. And advise the commuting taxpayer candidly about the standing exposure: as long as New York employment continues, the convenience-of-the-employer rule governs the paycheck (20 NYCRR 132.18(a)), the day count resets every January, and the statutory-residency test waits for any year the abode and the calendar align, which makes the annual review (days, abode status, the months the abode was maintained, usage) not a formality but the decisive exercise.
