N.C. Gen. Stat. § 63-86
After each assessment for taxes following the creation of the district, the board or boards of commissioners of the county or counties within which the district is located shall file with the district board the valuation of assessable property within the district. The district board shall then determine the amount of funds to be raised by taxation for the ensuing year in excess of available funds to provide for the payment of interest on and principal of all outstanding general obligation bonds as the same shall become due and payable and to pay all obligations incurred by the district in the performance of its lawful undertakings and functions.
The district board shall determine the number of cents per hundred dollars necessary to raise said amount and certify such rate to the appropriate board or boards of commissioners of the appropriate county or counties. The board or boards of commissioners of such county or counties shall include the number of cents per hundred dollars certified by the district board in its next annual levy against all taxable property within the district, which tax shall be collected as other county taxes are collected, and every month the amount of tax so collected shall be remitted to the district board and deposited by the district board in a separate account in a bank in the State. Such levy may include an amount for reimbursing the particular county for the cost to the county of levying and collecting any such taxes. The officer or officers having charge or custody of the funds of the district shall require security for protection of deposits as provided in the Local Government Budget and Fiscal Control Act.
