Nebraska taxes residents on all income. You can be a resident by domicile, or by keeping a home in the state and spending enough days there.
You are a Nebraska resident if you are domiciled in Nebraska, or if you maintain a permanent place of abode in the state and spend more than 183 days (6 months) there. Domicile alone also makes you a Nebraska resident even with fewer than 183 days of presence.
Nebraska treats a non-domiciliary as a resident when two things are true in the same year: you maintain a permanent place of abode in the state, and you spend more than 183 days (6 months) there. Meet both and Nebraska taxes you as a resident even if your true home is elsewhere. Domicile alone also makes you a Nebraska resident even with fewer than 183 days of presence.
Nebraska generally counts any part of a day in the state as a full day. Days add up across every trip during the year, not just one stay.
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.
