Rate Breakdown

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

How Property Tax Works in Santa Fe County

In Santa Fe County, property taxes are determined by a calculation involving the property’s taxable value and the local mill rate. The Santa Fe County Assessor’s Office is responsible for determining the market value of your property, which is then adjusted by the state-mandated assessment ratio of 33.33% to arrive at the net taxable value. This value is further protected by the "3% limitation," which restricts the annual increase in taxable value for residential properties unless there has been a change in ownership, new construction, or a change in land use.

The millage rate, or tax rate, is a composite figure determined by the New Mexico Department of Finance and Administration. This rate reflects the budget requirements of various taxing entities, including the county, school districts, and municipal governments. Your final tax bill is calculated by multiplying the net taxable value (after exemptions) by the local mill rate, expressed as dollars per $1,000 of taxable value.

Available Exemptions

New Mexico offers several statutory exemptions to reduce the tax burden for eligible property owners. To benefit from these, you must apply with the County Assessor’s Office:

• Head of Family Exemption: A $2,000 reduction in the taxable value of a primary residence for residents of New Mexico.
• Veterans’ Exemption: Qualified veterans or their surviving spouses may receive a reduction in taxable value of $4,000.
• Disabled Veteran Exemption: Veterans with a 100% service-connected disability rating are eligible for a full exemption from property taxes on their primary residence.
• Senior or Disabled Citizen Valuation Freeze: Homeowners aged 65 or older, or those who are permanently disabled, may be eligible to freeze the valuation of their primary residence, provided their modified gross income meets specific state thresholds.

Payment Schedule & Deadlines

Property tax bills in Santa Fe County are typically mailed by November 1st of each year. Taxes are due in two equal installments:

• First Half: Due on November 10th and becomes delinquent if not paid by December 10th.
• Second Half: Due on April 10th and becomes delinquent if not paid by May 10th.

If you prefer to pay in full, you may do so by the December 10th deadline to avoid interest and penalties. Failure to pay by these dates results in a 1% monthly interest charge and a penalty of up to 1% per month, capped at 10% of the delinquent amount. Continued non-payment can eventually lead to the sale of the property at a delinquent tax auction.

Appealing Your Assessment

If you believe the assessed value of your property is inaccurate or exceeds its fair market value, you have the right to file a formal protest. You must submit a written "Petition of Protest" to the County Assessor within 30 days of the date on your Notice of Value. It is recommended that you provide supporting documentation, such as recent appraisals, comparable sales data, or photographs of property condition issues, to substantiate your claim. Following the filing, a hearing will be scheduled with the County Valuation Protests Board to review your evidence.
