Nebraska Tax Residency (183-day rule)

Key parameters
Threshold	183 days
Period / Window	Tax year (1 Jan – 31 Dec)
Counting	Any part of a day
Alternative	Domicile
Additional requirements	Permanent place of abode

This applies to anyone with somewhere to stay in Nebraska, whichever state they treat as their own. You are a Nebraska resident if either of these applies:

• Domicile — Nebraska is your permanent home, the place you intend to return to whenever you are away.
• Abode plus days — you maintain a permanent place of abode in Nebraska and are present in the state for at least 183 days of the tax year, even where you are domiciled elsewhere.

The abode definition is broad. A permanent place of abode is a dwelling place permanently maintained by the taxpayer, and a dwelling place includes a house, apartment, room or other accommodation suitable for human occupation. A single room can therefore satisfy the limb where a larger property would not be needed.

• 183 qualifies, not 184. Nebraska sets the line at at least 183 days, so a count that would fall short in Iowa's neighbors to the east is enough here.
• A single room can be an abode. The definition reaches any accommodation suitable for human occupation that is permanently maintained, not only a house or apartment.
• Permanence, not size, decides. What matters is that the dwelling place is permanently maintained rather than how substantial it is.
• Two states can tax the same year as a resident year. Meeting the Nebraska test leaves your domicile elsewhere intact, with credits closing only part of the overlap.
• Domicile carries no threshold. Someone domiciled in Nebraska is a resident on that basis alone, whatever their count.

A resident is taxed on income from all sources while a nonresident pays only on Nebraska-source income, so an error usually surfaces as out-of-state earnings never reported while another state taxed the same income. The Department charges interest from the original due date and adds penalties for filing late and for underpaying, rising where an understatement is treated as more than an honest mistake. Professional tax advice is strongly recommended in situations like this.

A room kept year-round

You are domiciled in Kansas but keep a permanently rented room in Omaha and are in Nebraska for about 200 days. A room suitable for human occupation is a dwelling place, so both limbs hold and you are a resident.

A count landing exactly on the line

You maintain a Nebraska apartment and are present on exactly 183 days. Because the rule is at least 183 days, that is enough, where the same count would fall short in a state written as "more than 183."

Days without anything maintained

You spend around 190 days in Nebraska on rotating contracts, staying in motels booked as you go with nothing held between trips. Without a permanently maintained dwelling place the statutory route does not attach.
