Tax relief and valuation review
A homestead exemption, senior-relief program, or valuation protest can change the amount a homeowner owes—but only if the filing reaches the right local office in the correct window. Use the verified county guidance below as your working checklist, then confirm the current form and deadline with San Juan County Assessor's Office.
Relief programs
The filing guidance for this county is: Veteran certificate of eligibility must be presented January 1-April 30, 2026; head-of-family exemption claims are filed with the Assessor and renew automatically after approval. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationSan Juan County's 2026 application covers the low-income valuation limitation for owners age 65+ or totally disabled; the county form uses a $44,200 prior-year modified-gross-income limit.
San Juan County applies New Mexico's NMSA 7-36-21.3 valuation limitation: qualifying low-income owners age 65+ or disabled may freeze the value of a primary single-family dwelling; general residential limitation and statutory exceptions are governed by state law.
Appealing an assessment
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: Within 30 days after the 2026 Notice of Value is mailed; San Juan County says NOVs are mailed before April 1, usually near the end of March. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
