New Mexico property tax rates by county

What the figures are

This page reproduces DFA's weighted average property tax rate for each county, by class, in mills on net taxable value (Table 6, "weighted in proportion to taxable value of the tax district in which the rates appear"), and the same obligations as an approximate percent of assessed value (Table 7). Each is an average of the county's tax-district rates, not the rate in any one district. Period: tax year 2025 (rates certified in 2025, bills payable November 2025 and April 2026), from DFA's Property Tax Facts.

Net taxable value. "Assessed value in New Mexico is three times net taxable value, plus exemptions." Table 7's percent is "Obligations divided by net taxable value multiplied by 3; does not account for property tax exemptions because data on them is not currently available." (Property Tax Facts, Tables 6 and 7)

Residential and nonresidential. Residential and nonresidential rates differ because of yield control: "Since yield control has had a greater impact on residential rates than non-residential rates..." (Property Tax Facts)

• N/A means the county has no rate for that class. "Only Grant County has Copper Production (reported as Ad Valorem production)."
• Every Table 7 percent equals the Table 6 mills divided by 30 (mills ÷ 1,000 × one-third × 100), which is how the two tables relate; DFA's statewide Table 7 total is 0.927% for all property types.

Worked example: $100,000 of net taxable value

• Bernalillo County: $100,000 × 41.004 ÷ 1,000 = $4,100.40 a year.
• Dona Ana County: $100,000 × 29.107 ÷ 1,000 = $2,910.70 a year.
• Santa Fe County: $100,000 × 19.028 ÷ 1,000 = $1,902.80 a year.
• Median county: $100,000 × 24.180 ÷ 1,000 = $2,418.00 a year.

Under DFA's statement that assessed value is three times net taxable value plus exemptions, $100,000 of net taxable value corresponds to $300,000 of assessed value for a property with no exemptions; a property's own rate is its tax district's, not the county average.

How to appeal an assessment in New Mexico

1. File a petition of protest with the county assessor (Section 7-38-24 NMSA 1978); a hearing is scheduled before the County Valuation Protests Board: no later than 30 days after the mailing of the notice of value, as the county petition form states Section 7-38-24 (the Taxation and Revenue Department's FAQ says within 30 days after you receive the notice; counting from the mailing date is the earlier of the two).

The two sources word the start of the 30 days differently, so both wordings are given. Sources: New Mexico Taxation and Revenue Department, FAQ: disagreeing with a county assessor's valuation notice, read October 26, 2026; Valencia County Assessor, 2025 Protest Petition, read October 26, 2026. The official notice and the body hearing the appeal govern the dates; this is not legal advice.

Checks: Table 6 was read twice, independently, and both reads agreed for all 33 counties; every Table 7 percent equals the Table 6 mills ÷ 30 within 0.001 for all 33 counties and four classes, and N/A appears in the same cells of both tables; no county lies outside three interquartile ranges of the others and no two neighbouring rows repeat the same rates.
