How Property Tax Works

Santa Fe County's property tax system funds essential local services including schools, county operations, and various special districts throughout the region. Property owners pay taxes based on their property's assessed value multiplied by the applicable mill rate, which varies significantly depending on your location within the county due to different special taxing districts and school districts.

The effective tax rates in Santa Fe County range from approximately 2.28% to 3.25% of assessed value, depending on your specific district. Properties in the CI-R (Capital Improvement - Rural) district face lower rates at 0.022772 mills per $1,000 of taxable value, while those in the CI-N (Capital Improvement - North) district pay 0.032464 mills per $1,000. Your actual tax bill depends on your property's assessed value, available tax credits you've applied for, and the specific combination of taxing districts that serve your property location.

Supplemental Tax Bills

Supplemental taxes in Santa Fe County are triggered when property ownership changes, new construction is completed, or major improvements are made that increase the property's assessed value mid-tax year. These taxes cover the difference between what was originally assessed and the new higher assessment, prorated for the remaining portion of the tax year.

For example, if you purchase a home in March that was previously assessed at $200,000 but now appraises at $300,000, you would owe supplemental taxes on the additional $100,000 in assessed value for the remaining 9 months of the tax year. The calculation would be: ($100,000 ÷ $1,000) × your district's mill rate × (9 months ÷ 12 months) = your supplemental tax amount.

Example Calculation

$300,000 Home Value Example (CI-R District):

  • Assessed Value: $300,000
  • Less Head of Family Credit: -$2,000 (if applied for)
  • Net Taxable Value: $298,000
  • Annual Tax: $298,000 ÷ $1,000 × $22.77 = $6,785
  • Monthly Escrow: $565

$600,000 Home Value Example (CI-N District):

  • Assessed Value: $600,000
  • Less Head of Family Credit: -$2,000 (if applied for)
  • Net Taxable Value: $598,000
  • Annual Tax: $598,000 ÷ $1,000 × $32.46 = $19,411
  • Monthly Escrow: $1,618

$1,000,000 Home Value Example (CI-N District):

  • Assessed Value: $1,000,000
  • Less Head of Family Credit: -$2,000 (if applied for)
  • Net Taxable Value: $998,000
  • Annual Tax: $998,000 ÷ $1,000 × $32.46 = $32,395
  • Monthly Escrow: $2,700

All tax credits require application and approval. Contact the County Assessor for current application deadlines and requirements.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Santa Fe County collect property taxes through monthly escrow payments to ensure timely payment of your tax obligations. Your lender estimates your annual property tax bill, divides it by 12, and adds this amount to your monthly mortgage payment. The escrow account typically maintains a cushion of 2-3 months of tax payments to cover any increases.

Property taxes are paid in two installments: the first half is due by December 10th, and the second half is due by May 10th of the following year. Your lender will make these payments directly to Santa Fe County from your escrow account. You should receive an annual escrow analysis showing how your payments were applied and any adjustments needed for the coming year. Always verify that your lender has paid your taxes by checking with the County Treasurer, as you remain ultimately responsible for payment even when using escrow services.
