Property Tax Bills Across Powder River County, Montana

Property tax bills in Powder River County are based on the assessed value of a home, not its market price alone. Local taxing authorities apply their tax rates to that assessed value, and the result is the annual property tax bill.

With a median home price of $87,722, many homeowners in the county face bills that are below the national median property tax bill of $2,400. The county’s tax burden can still vary widely from one property to another. The 25th percentile tax bill is $297, while the 75th percentile reaches $1,198, and the 90th percentile climbs to $1,746.
