Local government entities set tax rates, which can vary widely within a state. This variation occurs because each county annually estimates the budget necessary to provide services and divides it by the total value of all taxable property within its jurisdiction, resulting in the property tax rate.

Comparing Big Horn County's rate to the national median, which stands at 1.02%, provides a perspective on how local rates align with broader trends.
