Delaware does not offer a part year resident return. Delaware Part-year residents may elect to file either a resident or non- resident return.
- Electing to file a resident return – this option may be advantageous if, during the period of non-residency, you had no income from sources in other states and/or your only income was from Delaware.
- Electing to file a non-resident return – This option may be advantageous if, during the period of non-residency, you had any income from other states or sources outside of Delaware.
