New York State and New York City Residency Tests

New York State Tax Residency Rules

Whether an individual is considered a resident of New York State or City can have a material impact on the individual’s income tax liability. A New York State resident is generally subject to New York State income tax on his or her worldwide income, whereas a nonresident is subject to New York State income tax only on income from New York State sources. The difference is even more significant in New York City. A New York City resident is generally subject to New York City income tax on his or her worldwide income, while a nonresident is not subject to New York City income tax regardless of the source of his or her income. Federal deductibility of state and local taxes depends on the applicable tax-year limits and the taxpayer’s circumstances.

New York State applies a multipart tax residency test based on whether you are domiciled in New York or are a statutory resident based on spending 184 days or more during the calendar year in New York State while maintaining a permanent place of abode (PPA) in New York for substantially all of the taxable year, subject to applicable exceptions.

Understanding Domicile vs. Residence

Generally, you are considered a New York State resident for income tax purposes if you are domiciled in the state. The terms domicile and residence are often used synonymously in casual conversation, but for New York State tax purposes, they have distinctly different legal meanings:

• Domicile: Your permanent and primary home — the place you intend to return to whenever you are away. You can have only one domicile at any given time.
• Residence: Any physical dwelling where you reside or maintain living quarters (houses, condos, apartments). An individual can have multiple residences across several states simultaneously.

Your New York domicile does not change until you demonstrate with clear and convincing evidence that you have abandoned your New York domicile and established a new domicile outside New York State. This requires demonstrating a primary shift in the focus of your life to the new location.

The Five Primary Domicile Factors

According to the New York State Department of Taxation and Finance Nonresident Audit Guidelines, tax auditors evaluate domicile using Five Primary Factors:

1. Home: The relative use, size, market value, and degree of maintenance of your New York residence compared to your out-of-state home. Auditors analyze where you truly "live."
2. Active Business Involvement: Your directorships, employment, active decision-making, and day-to-day management of business operations. (Note that in Matter of Knight, DTA No. 819485 (NYS Tax Appeals Tribunal 2006), the Tribunal held that "the presence of a suburban commuter at work or play in New York on most days, without more, does not create a New York domicile" and cancelled the State's tax assessment).
3. Time: The ratio of days spent in your new home state versus New York. Auditors examine overall lifestyle patterns rather than just raw day counts.
4. Near and Dear: The physical location of items of high sentimental or monetary value — family heirlooms, artwork, photo albums, pets, stamp/coin collections, and valuable personal property (often verified through insurance riders).
5. Family: Where your spouse and minor children live, and specifically where your minor children are enrolled in school.

Formalities ("Other Factors"): Steps such as changing your driver's license, registering to vote, moving bank accounts, updating vehicle registrations, or executing new estate planning documents are treated by auditors as relevant but not determinative. While necessary for consistency, these ministerial acts alone will not overcome negative primary factors.

Statutory Residency Test & The Permanent Place of Abode (PPA) Rules

New York's statutory residency rule is commonly called the "183-day rule," but the legal threshold is 184 days or more. Exactly 183 countable days does not satisfy the statutory day-count threshold. It does not establish nonresident status: domicile is a separate basis for residency. Statutory residency generally requires both 184 or more countable days and a qualifying permanent place of abode maintained for substantially all of the taxable year, subject to applicable exceptions. See New York Tax Law § 605(b)(1)(A)–(B) (PDF, pp. 3–4) for the State’s domicile and statutory-residency provisions, including the active U.S. armed-forces service exception to § 605(b)(1)(B). The “substantially all” abode-duration requirement is set out in 20 NYCRR § 105.20 (PDF).

You are a statutory resident of New York State if:

• You maintain a permanent place of abode in New York State for substantially all of the taxable year; and
• You spend 184 days or more in New York State during the taxable year.

What Constitutes a Permanent Place of Abode (PPA)?

A permanent place of abode is a dwelling place of a permanent nature maintained by the taxpayer that is suitable for year-round residential use (20 NYCRR § 105.20). However, key statutory exemptions and court rulings refine this definition:

• Residential interest and use: Ownership or payment alone does not settle PPA status. Matter of Gaied (2014) and Matter of Obus (2022) require attention to the taxpayer’s residential interest and actual relationship to the dwelling. Limited vacation use is not a blanket exemption for every second home.
• Duration and the 10-month policy: Beginning with tax year 2022, Audit Division policy generally interprets “substantially all of the year” as a period exceeding 10 months in acquisition or disposition years; the prior policy used more than 11 months. This is a general audit policy, not an absolute statutory safe harbor. Short-term rentals or temporary absences do not necessarily stop maintenance of a PPA, and successive New York dwellings may be combined. Review the actual dates and circumstances rather than relying on a single purchase or sale deadline. See Nonresident Audit Guidelines, pp. 49–51 (PDF).
• Full-time undergraduate students: The regulation excludes a residence maintained by a qualifying full-time undergraduate enrolled in a baccalaureate degree program and occupied while attending the institution. Graduate study does not receive this undergraduate exclusion. Review the enrollment and occupancy conditions in 20 NYCRR § 105.20(e)(1) (PDF).
• Corporate and shared apartments: Sharing does not automatically eliminate PPA status. Primary availability, personal residential use, reservation records, and any designated quarters matter. An apartment principally available to one executive can be a PPA even if others occasionally use it. See Nonresident Audit Guidelines, p. 47 (PDF).
• Uninhabitable dwellings and seasonal camps: Year-round suitability and essential facilities matter. A genuinely uninhabitable period requires evidence; travel, non-use, or routine improvements alone do not establish that a dwelling ceased to be a PPA.

Special Safe Harbor Exceptions for Domiciliaries

If your domicile remains New York, you can still qualify as a nonresident if you satisfy all three conditions of either Group A or Group B:

These are separate exceptions under Tax Law § 605(b)(1)(A)(i)–(ii) (PDF), explained in 20 NYCRR § 105.20(b) (PDF). Do not assume a day excluded for the 183-day statutory test is also excluded for these exceptions.

New York City Residency Rules

The rules for New York City residency mirror the New York State tests. You are a New York City resident if:

• Your domicile is located in one of the five NYC boroughs (Manhattan, Brooklyn, Queens, the Bronx, or Staten Island); or
• You maintain a qualifying permanent place of abode in NYC for substantially all of the taxable year and spend 184 days or more in the City during the calendar year, subject to applicable exceptions.

New York City residents are subject to NYC personal income tax on their worldwide income. Nonresidents of NYC owe no New York City income tax, regardless of where their income is earned.

Yonkers Tax Residency & Nonresident Earnings Tax

Yonkers is an independent city in Westchester County (not part of NYC). Yonkers imposes its own income tax rules:

• Yonkers Residents: Taxpayers domiciled in Yonkers, or maintaining a PPA and spending 184+ days in Yonkers, are subject to a Yonkers resident income tax surcharge on their NY State tax return.
• Yonkers Nonresidents: Nonresidents who earn wages or carry on a business/partnership in Yonkers are subject to the Yonkers Nonresident Earnings Tax.

New York State Estate Tax & The Infamous "Estate Tax Cliff"

In addition to personal income tax, New York is one of a minority of states that imposes a separate State Estate Tax (N.Y. Tax Law Article 26 § 952) with top tax rates reaching 16%. High-net-worth individuals and business owners must understand that state estate tax jurisdiction is governed strictly by legal domicile, not statutory residency:

• Governed Strictly by Domicile (Not the 183-Day Rule): Unlike New York personal income tax — which can be triggered by either domicile or the 183-day statutory residency test — New York estate tax liability is determined exclusively by legal Domicile. Spending 184 days in New York or maintaining a permanent place of abode does not, by itself, trigger NY estate tax if your legal domicile is elsewhere. However, physical time spent in New York remains a primary evidentiary factor used by auditors to challenge your claimed out-of-state domicile.
• Worldwide Scope for NY Domiciliaries: If you die as a New York domiciliary, New York State taxes your entire worldwide gross estate — including all cash, stocks, bonds, brokerage accounts, business interests, and intangible assets, regardless of where in the world they are located (excluding only real estate and tangible property physically situated in another state).
• Limited Scope for Non-Domiciliaries: If you successfully establish domicile outside New York (e.g., in Florida, Texas, or Wyoming, which impose 0% state estate tax), New York State estate tax applies only to real property (real estate) and tangible personal property physically located within New York State. Your intangible wealth (stocks, bank accounts, investment portfolios) escapes NY estate tax entirely.
• The Infamous NY Estate Tax "Cliff" (2026 Exclusion & Threshold): Unlike the federal estate tax exemption (which only taxes amounts exceeding the threshold), New York enforces a severe statutory cliff. For 2026, New York's Basic Exclusion Amount is $7,350,000. An estate valued at $7.35 million or less owes $0 in NY estate tax. However, if a deceased domiciliary's taxable estate exceeds 105% of the exclusion ($7,717,500), the state exemption is completely eliminated (0%), and New York taxes the entire estate starting from dollar one. This creates an immediate, multi-hundred-thousand-dollar tax penalty the moment an estate crosses $7,717,500.
• The 3-Year Gift Clawback Rule: Under N.Y. Tax Law § 954(a)(3), taxable gifts (under IRC § 2503) made by a NY domiciliary within 3 years prior to death are added back into the NY gross estate for calculation purposes (excluding real or tangible property outside NY, gifts made while a non-resident, or gifts made after January 1, 2032 when the clawback statutorily sunsets).
• The Cliff-Clawback Interaction Trap: A critical danger arises when a family makes gifts to reduce an estate below the $7.35 million exemption threshold. If the donor dies within 3 years, § 954(a)(3) claws those gifts back into the taxable estate. If the clawed-back gifts push the total gross estate past the 105% cliff threshold ($7,717,500), the exemption is completely wiped out, subjecting the entire estate to full 16% NY estate tax — leaving the estate in a far worse tax position than if no gifts had been made.
• No Spousal Portability in New York: Unlike federal estate tax rules (which allow a surviving spouse to inherit the unused portion of a deceased spouse's exemption), New York does not allow spousal portability. If the first spouse to die does not fully utilize their $7.35 million NY exemption through credit shelter or bypass trust planning, that $7.35 million state exclusion is permanently lost.

Moving During the Year

A change of domicile can create part-year residency, but it does not automatically limit the statutory residency test to the post-move period. The full-year day count and abode history still matter: a person can satisfy statutory residency for the full year despite changing domicile during it. See Nonresident Audit Guidelines, p. 51 (PDF).

Moving-year income can raise a separate issue. In Matter of Garg, DTA No. 829955 (2023), the Division of Tax Appeals treated gain from a business sale as accruable to the taxpayers’ New York resident period because the events fixing the right to receive the income and its amount occurred before the later payment. Residency status and income-sourcing or accrual rules should therefore be reviewed together when a move and a transaction occur in the same year.

Counting Days in New York & Statutory Exceptions

Under 20 NYCRR § 105.20, any part of a day spent in New York counts as a full day ("a minute is a day"). You do not need to stay overnight or visit your home for the day to count. In Matter of Zanetti v. NYS Tax Appeals Tribunal, 128 A.D.3d 1131 (3d Dept. 2015), a taxpayer who spent 26 partial days flying in or out of NY on a private jet had all 26 partial days counted, triggering statutory residency.

Day Count Exceptions

• Travel Exception: Presence in NY is disregarded if it is solely to board outbound transit (plane, train, ship, bus) or passing through NY en route between two non-NY locations. Activity incidental to travel (buying gas, terminal meals, ATM use, meeting a limousine) does not forfeit the exception, provided the traveler does not engage in non-travel activities (e.g. business meetings or visiting friends). See NY Nonresident Audit Guidelines.
• Medical Exception: A limited, case-law-based exception concerns qualifying confinement in a New York medical facility for treatment. It is not a blanket statutory exclusion for every illness-related visit or stay. Outpatient appointments and time outside the facility require separate review. See Nonresident Audit Guidelines, pp. 53–54 (PDF).

Burden of Proof & Audit Evidence Hierarchy

Under New York law, the taxpayer bears the burden of proving non-residency by clear and convincing evidence on domicile, and by precise daily documentation for statutory residency (Matter of Boniface, DTA No. 829018 (2021)).

Residency audits demonstrate a strict hierarchy of evidence where contemporaneous, objective proof defeats secondhand or reconstructed accounts:

• The Limited Lesson of Matter of Knight: In Matter of Knight (DTA No. 819485), the Tribunal gave no weight to particular hearsay statements in an investigator’s report and a building manager’s later letter. The decision supports checking the source, timing, and firsthand basis of audit evidence; it does not mean every later-created record or witness statement is automatically excluded.
• Specific daily records matter: In Matter of Ruderman, 170 A.D.3d 1442 (3d Dept. 2019), a Florida domiciliary with substantial New York connections did not overcome the statutory-residency assessment because his testimony and affidavits lacked sufficiently specific dates and contained contradictions. The court also rejected inferring out-of-state days from a general travel pattern.
• Clear and convincing proof can be assembled: In Matter of Robertson, DTA No. 822004 (2010), the Tribunal accepted a detailed combination of testimony and contemporaneous calendar and travel evidence for disputed New York City days and cancelled the deficiency. The practical lesson is to preserve day-specific records that can be explained and corroborated, rather than relying on a single record type.
• Domicile365 Hardware-Attested & Crypto-Signed Logs: In contrast to unreliable hearsay or retroactively created logs, Domicile365 automatically records your daily location using hardware-level device verification (Apple App Attest & Android Key Attestation) and generates cryptographically signed, tamper-evident logs. This proves to auditors that location data originated from a genuine, un-spoofed mobile device in real time and provides strong evidence to assist with your tax defense.
• Cellular Carrier Logs: Auditors frequently subpoena cellular call detail records (CDRs) and data/text tower pings (AT&T, Verizon, T-Mobile) to verify locations.
• EZ-Pass & Toll Records: A major audit focus in the tri-state area. Audit Trap: Avoid sharing EZ-Pass tags across family vehicles, as auditors assume the account owner was present in the vehicle. Each family member should maintain an independent EZ-Pass tag.
• Credit Card & ATM Records: Monthly statements are audited for physical location. Watch out for "false positive" NY transactions caused by recurring online subscriptions, auto-pays, or dry cleaners with cards on file.
• Electronic Calendars & Diaries: Outlook and Google calendars carry less evidentiary weight on audit because they can be retroactively altered, unless backed up by cryptographically verified location proof.
