Delaware Residents who work in another state
If your domicile was in Delaware for any part of the year, or if you lived in Delaware for more than 183 days, you are a Delaware resident.

To file a Delaware return use Form 200-01R or 200-03EZ and for additional assistance or information see the Form 200-01R instructions. Please note that full-time students who are residents of another state remain residents of that state.
If you are a Delaware resident that works in another state you will be taxed on the income earned in the other state by Delaware. This is because Delaware taxes all income its residents make regardless of source. Additionally you may be taxed by the state in which the income was earned because the other state also taxes this income. To avoid dual taxation on such income Delaware offers a tax credit for taxes on such income that were paid to another state. To file for this credit you will need to file Schedule 1 (which can be found in either Form 200-01R or 200-03EZ) and attach it to a signed copy of the return you filled with the other state. For additional information see the Form 200-01R instructions.
