The Assessor's Office compiles a "tax roll", listing each property. The property may include improvements (house, barns, sheds, etc.). "Full Value" is the appraised value determined by a San Juan County Appraiser. "Taxable Value" is one third (33 1/3%) of the "Full Value" of the taxed item. The "Tax Rate" is expressed in dollars of tax per thousand.
The tax rate is established every year by the State Department of Finance and Administration based on the budgets submitted to the State by the county, schools, cities and the Voters, through the approval of bond issues. The New Mexico Department of Finance and Administration prepares the “Certificate of Tax Rates” every September.
