Form SC 1040TC is the form needed by all South Carolina residents who worked in another state. This form is a supplemental form that should be filed with Form SC 1040. This form prevents South Carolina residents who work in other states from facing dual taxation on the income they earned from other states. Without filing Form SC 1040TC, residents who work in other states would be taxed by both South Carolina (the state of residency) and the other state (where the income was earned) on all income earned outside of South Carolina. Form SC 1040TC prevents dual taxation by issuing a South Carolina credit for all taxes paid to other states.
