New Jersey taxes residents on all income and, like its neighbors, applies a statutory residency test that can capture people who keep a place in the state and spend more than half the year there.
You are a New Jersey resident if you are domiciled there, or if you keep a permanent place of abode in New Jersey and spend more than 183 days (184 or more) in the state. A statutory resident is taxed as though domiciled in New Jersey for the whole year.
New Jersey treats a non-domiciliary as a resident when two things are true: you maintain a permanent place of abode in the state, and you spend more than 183 days there during the year. Because the threshold is more than 183, 184 days is the trigger.
New Jersey has offered little formal guidance on exactly how to calculate days, so a careful, well-documented count is especially important.
Physical presence in New Jersey for any part of a calendar day is generally counted as a full day, including brief visits for shopping, appointments, or time at an airport within the state. Days add up across every trip all year.
In an audit the burden is on you to prove the days you were outside the state. A contemporaneous day-by-day log, backed by phone, card, and travel records, is the strongest defense.
DayStayed resolves each day to one jurisdiction and shows your running count against every threshold you watch.
