Connecticut taxes residents on all income and applies a statutory residency test to non-domiciliaries who keep a home in the state and spend more than 183 days there.
You are a Connecticut statutory resident if you maintain a permanent place of abode in the state and spend more than 183 days (184 or more) there in the year, even if domiciled elsewhere. Domicile is the separate first path to residency.
Connecticut residents include anyone who maintains a permanent place of abode in the state and spends, in the aggregate, more than 183 days of the year in Connecticut. The state’s instructions specify the abode must be maintained for a full year. The definition is broad: even a furnished room maintained for your use in a relative’s house can count.
Connecticut counts any part of a day in the state as a full day, with one narrow exception: time spent in Connecticut solely while passing through to a destination outside the state does not count. Days accumulate across the 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.
