Quick answer: what the 183-day statutory residency rule is, which states use it (and which don't), what counts as a day, and what it means for Florida domicile.

Key Takeaways

  • In most states with the rule, spending more than 183 days there plus keeping a permanent place of abode makes you a "statutory resident"
  • The day count alone is rarely enough—the abode requirement is the second half of the test
  • California does not use a 183-day rule; Oregon and Hawaii use 200 days
  • Staying under 183 days does NOT guarantee safety—domicile is a separate test

What is the 183-Day Rule?

The 183-day rule is a statutory residency test some states use to tax people who live there most of the year without claiming to be domiciled there. In the states that use it, you are taxed as a resident if you both (1) maintain a permanent place of abode in the state and (2) spend more than 183 days of the year there—even if your legal domicile is somewhere else.

Critical: Statutory residency is separate from domicile. You can be taxed as a statutory resident of one state while domiciled in another, which can produce double-taxation situations.

How the Big States Actually Apply It

State Rule
New York 184+ days and a permanent place of abode maintained for substantially all of the year (more than 10 months under current audit guidelines)
New Jersey More than 183 days and a permanent home in NJ (N.J.S.A. 54A:1-2)
Connecticut More than 183 days and a permanent place of abode
Oregon More than 200 days and a permanent place of abode (ORS 316.027)
Hawaii More than 200 days creates a rebuttable presumption of residency
California No 183-day rule. Residency turns on domicile and whether your presence is "temporary or transitory"; more than nine months creates a rebuttable presumption (RTC §17016)
Not every dwelling counts: New York's highest court held in Matter of Gaied v. New York State Tax Appeals Tribunal, 22 N.Y.3d 592 (2014), that merely maintaining a dwelling isn't enough—you must have a residential interest in it (a place you actually use as your own residence). A property you own but where only relatives live is not automatically your "permanent place of abode."

What Counts as a "Day"?

  • General rule (NY and most abode states): Presence for any part of a calendar day counts as a full day
  • Travel exception: New York regulation 20 NYCRR 105.20(c) excludes days when your presence is solely for boarding a plane, ship, train, or bus to an out-of-state destination, or while traveling through New York to a destination outside the state. Connecticut has a similar in-transit exception.
Good to Know: Auditors verify day counts with flight records, credit card statements, EZ-Pass data, and cell phone records. Keep your own records so you can prove where you were.

Common Misconceptions

"If I spend less than 183 days, I'm safe"

FALSE. A state can still tax you as a domiciliary resident regardless of days. The day count only addresses statutory residency—domicile is a separate, facts-and-circumstances test.

"I only need to count work days"

FALSE. All days count—weekends, holidays, sick days, and vacation days spent in the state.

"An airport layover counts as a New York day"

FALSE. Days spent solely in transit between two points outside New York are disregarded under 20 NYCRR 105.20(c). A layover becomes risky only if you leave transit and conduct other activities in the state.

How to Track Your Days

  • Keep a daily location calendar or use a day-counting app
  • Save flight records, hotel receipts, and credit card statements
  • Document days you were NOT in the high-tax state, not just days you were

What This Means for Florida Residents

Florida has no state income tax and no day counting. As a Florida resident, your risk runs the other way: spending too much time in your old state—while keeping a home available there—can make you a statutory resident of that state even though your domicile is Florida.

Two-Part Test Days + a permanent place of abode. Manage both, not just the calendar.

Frequently Asked Questions

Quick answers to common questions

The 183-day rule is a statutory residency test used by states such as New York, New Jersey, and Connecticut. If you maintain a permanent place of abode in the state and spend more than 183 days there during the year, the state can tax you as a resident regardless of where you claim domicile.
183 day rulewhat isdefinition
No, Florida has no state income tax, so there's no day counting for Florida. However, if you're a Florida resident spending substantial time in other states, those states may count your days there.
florida183 daysapply
No. California residency is based on domicile and whether your presence in the state is for a temporary or transitory purpose. Spending more than nine months of the year in California creates a rebuttable presumption of residency under Revenue and Taxation Code section 17016, but there is no 183-day statutory residency test.

In New York and most states with the rule, presence for any part of a calendar day counts as a full day. New York excludes days spent solely in transit between two points outside the state, such as boarding a flight to an out-of-state destination.

Not necessarily. States can still claim you as a resident based on domicile even if you spend fewer than 183 days there. The 183-day rule is just one test; domicile is another.
