N.C. Gen. Stat. § 105-163.10
The amount deducted and withheld under this Article during any calendar year from the wages or compensation of an individual shall be allowed as a credit to that individual against the tax imposed by Article 4 of this Chapter for taxable years beginning in that calendar year. The amount deducted and withheld under this Article during any calendar year from the compensation of a nonresident entity shall be allowed as a credit to that entity against the tax imposed by Article 4 of this Chapter for taxable years beginning in that calendar year. If the nonresident entity is a pass-through entity, the entity shall pass through and allocate to each owner the owner's share of the credit.
If more than one taxable year begins in the calendar year during which the withholding occurred, the amount shall be allowed as a credit against the tax for the last taxable year so beginning. To obtain the credit allowed in this section, the individual or nonresident entity must file with the Secretary one copy of the withholding statement required by G.S. 105-163.3 or G.S. 105-163.7 and any other information the Secretary requires.
