To calculate property taxes you need 2 pieces of information:

Formula:
(Assessed Value ÷ $1,000) x Tax Rate = Tax Bill
Example:
Assessed Value = $400,000
Tax Rate = 8.00
Tax Bill = ($400,000 ÷ $1,000) x 8.00 = $3,200
How do I find my Tax Rate?
Your tax rate is based on the Tax Code Area (TCA) of your property. TCAs are geographical areas covered by different combinations of tax levies. There are 20 TCAs in San Juan County. Your TCA is printed on your Notice of Value and on your Tax Statement.
