Residents of applicable states who enter military service and are assigned to duty outside those States remain residents of those States for tax purposes unless they fulfill all three of the following conditions.
They maintain no place of abode in their State of legal residence during the taxable year.
They do maintain a place of abode outside that State for the entire taxable year.
They spend no more than 30 days in that State during the taxable year.
The following are not considered places of abode under condition 2
An abode maintained while on temporary duty or while attending a specialized training school away from your permanent duty station is not considered a place of abode under condition 2.
A member who is otherwise considered to maintain a place of abode outside his or her State of legal residence does not lose the place of abode solely because of performance of duty at another location if such place of abode is still maintained by the member.
Quarters occupied by a barracks, on shipboard, or in bachelor officer quarters at your permanent duty station are not considered a place of abode under condition 2. This restriction applies only to New Jersey and New York residents.
