Any taxing agency, including a taxing agency having its own system for the levying and collection of taxes or assessments, but excluding a county, may by ordinance or resolution of its governing body provide that the county recorder shall file, record, index, and make notations upon, written instruments pertaining to the assessment, sale, and deeding (whether to such agency or a purchaser therefrom) of property taxed or assessed by such agency in the same manner and with the same effect as provided in this division with respect to comparable instruments pertaining to property subject to county taxes, and the county recorder shall comply with such ordinance or resolution upon payment of the same fees as if the taxing agency were the county. The recorded duplicate of any deed to a taxing agency other than the State or county shall be forwarded by the county recorder to the officer designated in the ordinance or resolution.
