North Carolina Administrative Code Title 17 — Revenue
17 NCAC 05C .0605 — When A State Has Jurisdiction
In the case of any "state," as defined in G.S. 105-130.4, other than a state of the United States or political subdivision of such state, the determination of whether such "state" has jurisdiction to subject the taxpayer to a net income tax shall be made as though the jurisdictional standards applicable to a state of the United States applied in that "state." If jurisdiction is otherwise present, such "state" is not considered as without jurisdiction by reason of the provisions of a treaty between that state and the United States. SECTION .0700 - APPORTIONABLE AND NONAPPORTIONABLE INCOME
