Property Tax Bills Across Natrona County, Wyoming

Property tax bills in Natrona County are based on the assessed value of a home, not its market price alone. Local taxing authorities apply the county’s tax rates to that assessed value to determine the final bill, so two homes with similar market values can still owe different amounts if their assessments or tax rates differ.

Several factors shape what a homeowner pays, including the property’s assessed value, the location of the home, and the mix of local levies that fund schools, services, and other public needs. With a median home price of $230,437, tax bills can vary widely across the county. The 25th percentile tax bill is $940, while the 75th percentile is $2,261 and the 90th percentile reaches $3,129.

That range matters for homeowners because property taxes can significantly affect monthly housing costs and long-term affordability. In Natrona County, the highest median tax bill is $2,101.00 in Bar Nunn, while the lowest is $241.00 in Hiland, showing how location can strongly influence what a homeowner owes.
