Tax bills & filing dates
These are the dates and qualifications recorded in the directory. Confirm your tax year and current deadline with the official office and your property’s notice.
- Tax bill mailing
- November 1, 2026 or earlier, under the New Mexico county-treasurer annual schedule; county-specific mailing practices may vary.
- Payment deadline
- 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.
- Assessment appeal
- 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.
Exemptions & appeals
View exemption application (opens in a new tab)Exemption filing
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.
Senior relief
New Mexico's low-income valuation limitation is available to an owner age 65 or older or disabled who owns and occupies a single-family primary residence and satisfies the statutory modified-gross-income test. File proof of age or disability, occupancy, and income with the county assessor within 30 days after the 2026 Notice of Valuation. The county assessor's 2026 form and current NM Taxation and Revenue Department threshold control eligibility.
Valuation limits
New Mexico's statewide residential valuation limitation under NMSA 7-36-21.2 and 7-36-21.3 generally limits the annual increase in assessed value for eligible residential property to 3%, with statutory exceptions including new property, change of ownership, physical improvements, permitted-use or zoning changes, and eligibility changes. Qualifying low-income owners age 65 or older or disabled may instead receive a valuation freeze at the qualifying year.
