Residency Status Information for Delaware Returns
Residents: Residents are individuals:
- Who are domiciled in Delaware for any part of the tax year, or
- Who maintain a place of abode in Delaware and spend more than 183 days in Delaware during the year.
Part-year resident: Part-year residents are individuals who are Delaware residents for only a portion of the tax year. Part-year residents can elect to file either:
- A resident return. This option is usually best if, while a nonresident, the individual has no income from sources outside Delaware, or
- A nonresident return. This option is usually best if, while a nonresident, the individual has income from sources outside Delaware.
Nonresidents are individuals who are not Delaware residents at any time during the year.
Military Personnel / Military Spouses
Residents: Military personnel who are residents of Delaware upon entering military service remain residents of Delaware for income tax purposes until proof of change of home of record has been made. A change in legal residence is documented by filing DD Form 2058 and DD Form 2058-1 with the military personnel office.
Nonresidents: Nonresident military personnel stationed within Delaware are not required to file a Delaware income tax return unless they have earned income from Delaware sources other than military pay.
Military spouses: Under the Military Spouses Residency Relief Act, a military spouse’s state of residence does not change when moving to a new state to be with a servicemember stationed there if the residence or domicile is the same for the service member and spouse.
