How this is calculated
The effective property tax rate is the median real-estate tax bill divided by the median home value — both for owner-occupied homes, from the U.S. Census Bureau's American Community Survey (ACS 5-year estimates)1. Median income is also from the ACS1. Federal and state income-tax figures use IRS2 and Tax Foundation3 data.
About Costilla County, CO
Costilla County’s effective property tax rate of 0.315% sits well below Colorado’s statewide median of 0.386%, placing it 48th among the state’s 64 counties. The gap widens further against the national median of 0.794%, meaning owners here pay less than half the share of home value that a median U.S. county collects. On a median home value of $184,700, that rate yields an annual tax bill of about $582 — a figure shaped as much by the area’s lower property values as by the rate itself. Household income in the county averages $36,861, with per-capita income at $28,445. Communities such as Fort Garland, Blanca, and Chama anchor this sparsely populated stretch of southern Colorado, where the tax climate leans lighter than most of the country.
