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 Los Alamos County Assessor's Office.
Relief programs
The filing guidance for this county is: Within 30 days of the April 1, 2026 Notice of Value; Los Alamos County says current-year exemption applications must be filed within that period. Use the official form or application channel, provide the residence and ownership documentation requested, and keep a copy of the submission.
Open homestead applicationLos Alamos County's 2026 form: owner age 65+ or 100% disabled with 2025 modified gross income of $44,200 or less may qualify for the valuation freeze under NMSA 7-36-21.3.
New Mexico NMSA 7-36-21.2 and 7-36-21.3 generally limit annual assessed-value growth for eligible residential property to 3%; statutory exceptions apply, and qualifying low-income owners age 65 or older or disabled may receive a valuation freeze.
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: April 1-May 1, 2026; Los Alamos County published a 2026 NOV mail date of April 1 and requires protests within 30 days. If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
