Office names and responsibilities vary even within a state. The directory classifies the reviewed New Mexico records under the following administrative models.
Repeated guidance can reveal a common state calendar, but a county notice, local ordinance, installment schedule, or special program can still control an individual property. The entries below are shown only when the same reviewed wording appears in at least two New Mexico records.
For tax year 2026, New Mexico county treasurers mail property-tax bills on or before November 1, 2026; the first-half payment is due November 10, 2026 and avoids interest and penalty if paid by December 10, 2026; the second-half payment is due April 10, 2027 and avoids additional charges if paid by May 10, 2027.
For tax year 2026, file a petition with the county assessor by the later of April 1, 2026, or 30 days after the 2026 Notice of Valuation is mailed. The petition may challenge value, classification, allocation, denial of an exemption, or a valuation limitation; New Mexico law does not provide a protest of the tax rate itself.
For 2026, head-of-family, veteran, and other qualifying exemptions are claimed with the county assessor. New Mexico requires annual property changes and returns to be reported by the last day of February; the county assessor's form and instructions control any additional filing rule. A low-income valuation-limitation application must be filed within 30 days after the 2026 Notice of Valuation.
