authorize the cooperation of counties for purposes of operating an office of county director of equalization.

This bill authorizes counties in South Dakota to work together to operate a shared office for county directors of equalization. It directly affects county governments by allowing them to collaborate on administrative functions related to property assessment and tax equalization. The key provision permits multiple counties to pool resources and staff for this specific role, potentially reducing individual county costs. The legislation focuses on operational cooperation rather than changing existing tax laws or assessment standards.
