Property Tax Bills Across San Juan County, New Mexico
Property tax bills in San Juan County are based on the assessed value of a home and the local tax rate applied to that value. When a property’s market value rises, the assessed value can increase as well, which may lead to a higher tax bill. Local taxing authorities then use that assessment to calculate what a homeowner owes each year.
Several factors can affect the final bill, including the home’s value, the tax rate, and any local levies that apply. For homeowners, this means two similar homes can still have different tax bills if their assessed values or taxing districts differ. In San Juan County, the median home price is $103,862, while tax bills vary widely, with the 25th percentile at $218 and the 75th percentile at $1,558.
