The same three members serve on the county board of equalization and on the county excise board. Different roles are assumed by the members depending on the time of year either board is required to meet.

The county excise board reviews and approves the budgets of some of the political subdivisions within the county, and sets the ad valorem tax rates in keeping with the Constitution and Statutes of Oklahoma.
