Data Story
About Property Taxes in Carbon County, Montana
Carbon County's lowest rate, highest values
Carbon's 0.548% effective tax rate is the nation's lowest in this dataset, yet the median home value of $379,300 generates a $2,080 tax bill—near the national median of $2,690. This reflects Carbon's unusual position as a low-rate county with premium properties.
Second-lowest rate, highest home values
Carbon ranks second in Montana for lowest effective rate at 0.548%, just below Broadwater's 0.606%. With median home values of $379,300—the highest in this dataset—the county's median tax of $2,080 exceeds the state median by $278, a testament to property values outpacing the low rate.
Carbon combines low rates with premium prices
Carbon's 0.548% rate trails Broadwater (0.606%) and Beaverhead (0.665%), but its $379,300 median home value far exceeds both neighbors. This creates a paradox: the lowest rates paired with the highest absolute tax bills in southwest Montana.
Annual tax bill on median home
A median-priced home valued at $379,300 in Carbon County generates an annual tax bill of approximately $2,080. With a mortgage, expect about $1,980; without one, roughly $2,219 annually.
High values warrant careful assessment review
Carbon County's premium home values mean even small percentage errors in assessment translate to hundreds in taxes. Request a full reassessment if recent comparable sales suggest your home's appraised value exceeds its true market worth.
