Rate Breakdown

Property taxes in San Juan County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in San Juan County

Property taxes in San Juan County are calculated based on the assessed value of your property and the current millage (tax) rate. Here’s how the process works:

• Assessment: The San Juan County Assessor’s Office determines the taxable value of your property annually, based on market conditions and property characteristics.
• Millage Rate: Tax rates are set by local taxing entities (e.g., school districts, municipalities) and are applied per $1,000 of assessed value. For example, a 0.0100 mill rate means $10 in tax per $1,000 of assessed value.
• Calculation: Your tax bill = (Assessed Value × 55% for residential property) × Mill Rate.

Taxes fund local services like schools, roads, and emergency services. Notices are typically mailed in July, with payments due by November 30.

Available Exemptions

San Juan County offers several exemptions to reduce property tax burdens for eligible residents:

• Primary Residence (Homestead) Exemption: Reduces the taxable value of your primary home by up to 45% of its fair market value.
• Senior Citizen Exemption: Residents aged 65+ may qualify for a reduction based on income limits.
• Disabled Veteran Exemption: Veterans with a service-connected disability of 10% or more may qualify for partial or full exemptions.
• Indigent Abatement: Low-income homeowners may apply for temporary relief.

Applications for exemptions must be filed with the San Juan County Assessor’s Office by the annual deadline (typically September 1).

• Installment Option: Taxes may be paid in two installments (November 30 and May 31) if the total bill exceeds $100.
