The credit for taxes paid to another state is automatically calculated in your account when you add a Nonresident return to your already created Resident Delaware return if you pay taxes to both Delaware and another state.
Part-Year Residents will have to manually claim the credit for taxes paid to another state by following the instructions outlined below.
Delaware may request a copy of the other state's tax return before processing the return.
For more information on this credit please see the Delaware DOR website.
