Calculating Property Taxes

How to estimate your 2023 property taxes

Actual Value x Assessment Rate x Mills = Property Taxes

  • Actual Value is set by the County Assessor and can be found on Notices of Valuation and Tax Notices
    For 2023 only, subtract $55,000 for each parcel with a residence. Subtract $30,000 for each parcel with a commercial building.
  • Assessment Rate is set by the State Legislature and State Property Tax Administrator:
    • 27.9% for most non-residential property
    • 6.7% for most residential property
  • Mill Levies are set by local taxing entities. The sum of Mills that apply to a given property is used to calculate taxes. 
    Mills should be divided by 1000 to calculate taxes. 2024 Mill Levies will be set in late December 2024.
    The following are the 2023 Mill Levies:
    • 19.641 San Juan County (all property in SJC)
    • 15.484 School District #1 (all property in SJC)
    • 10.560 Town of Silverton (property within Silverton)
    • 08.200 Durango Fire Protection District (property in S. County)
    • 00.347 SW Water Conservation District (all property in SJC)
