The tax commissioner shall administer this chapter with respect to an income tax exemption or credit and has the same powers as provided under section 57-38-56 for purposes of this chapter. The secrecy provisions of section 57-38-57 do not apply to exemptions or credits received by taxpayers under sections 40-63-04, 40-63-06, and 40-63-07, but only when a local zone authority inquires of the tax commissioner about exemptions or credits claimed under sections 40-63-04, 40-63-06, and 40-63-07 with regard to that local zone authority or to the extent necessary for the tax commissioner to administer the tax exemptions or credits.
