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.
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) |
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.
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.
