Residency Status Information for South Carolina Returns
Residents: Residents are individuals:
- Who maintain South Carolina as their permanent home; AND
- For whom South Carolina is the center of their financial, social and family life; AND
- When they are away, South Carolina is the place to which they intend to return.
Part-year residents: Part-year residents are individuals who are South Carolina residents for only a portion of the tax year. Part-year residents can file either a resident or a nonresident return, choosing the way that is most advantageous to them:
- A resident return: If they elect to file as a full-year resident, file SC1040, reporting all income as though they were a resident for the entire year. They will be allowed a credit for taxes paid on income taxed by South Carolina and another state. To claim this credit, they must complete Form SC1040TC and attach a copy of the other state's income tax return.
- A nonresident return: If they elect to file as a nonresident, file SC1040 with Schedule NR. They will be taxed only on income earned while a resident in South Carolina and will prorate their deductions and exemptions. All personal service income earned in South Carolina must be reported to this state.
Nonresidents: Nonresidents are individuals who are not South Carolina residents at any time during the year. They will file SC1040 with Schedule NR.
Married couple, one is a resident, one is a part-year resident: If they file a joint federal return, they must file a joint South Carolina return SC1040 with Schedule NR (same as part-year residents file a nonresident return). The resident spouse will report to South Carolina all income for the entire year. The nonresident spouse will only report income earned in South Carolina, if any.
Military Personnel/Military Spouses
Residents: Military personnel who are residents of South Carolina upon entering military service remain residents of South Carolina 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 and spouses stationed within South Carolina are not required to file a South Carolina income tax return unless they have earned income from South Carolina 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.
