What this state guide covers
A quick view of the questions, practical details and source notes below.
Updated August 23, 2026. Quick answer: New Mexico runs a value freeze for owners who are 65 or older (or disabled) and whose modified gross income is under an indexed limit — the figure the state last published is $42,900, set for tax year 2025 by P.T.D. Order No. 24-36 — and a separate property-tax rebate claimed on the income-tax return. The programme is good. The deadline is the problem: the application is due no later than thirty days after the assessor mails your notice of valuation — a moving date, keyed to a letter, not a fixed day on the calendar. Notices go out around April 1. Miss the window and you wait a year.
What New Mexico offers
- The valuation limitation — what it actually freezes — NMSA 1978 § 7-36-21.3(A): the valuation for property taxation purposes of a single-family dwelling owned and occupied by a person who is 65 or older, or disabled, and whose modified gross income for the prior taxable year did not exceed the limit “shall not be greater than the assessed valuation of the property for property taxation purposes” for the tax year in which the owner qualifies and applies. It fixes the value on the roll, not the rate — if your district’s rate rises, your bill still rises.
- The income limit — and the number the state last published — The statute names a floor of $35,000 and then indexes it. The Taxation and Revenue Department publishes the resulting figure each year by order. The most recent order on the Department’s own page when we read it is P.T.D. Order No. 24-36, dated November 26, 2024, which sets the limit for tax year 2025 at modified gross income not exceeding $42,900. “Modified gross income” means what it means in the Income Tax Act.
- Three years of proof, then it runs itself — § 7-36-21.3(B): an owner who applies and files proof of income eligibility “for the three consecutive years immediately subsequent to the tax year for which the application is made need not claim the limitation for subsequent tax years if there is no change in eligibility”, and “the county assessor shall apply the limitation automatically” until eligibility changes. Subsection C carries the same relief for owners who had already held it for three consecutive years before 2020, subject to the assessor asking for updated income information.
- The head-of-family exemption — every resident, any age — § 7-37-4(A) exempts up to $2,000 of the taxable value of residential property owned by a New Mexico resident head of a family, including property held in a grantor trust. New Mexico computes taxable value by dividing the assessor’s value by three (3.6.6.10 NMAC), so $2,000 of taxable value is $6,000 of value on the assessor’s roll. The definition is wide: a married person (one spouse only), a widow or widower, a head of household supporting a related person, a single person (one per household), or a member of a condominium association who pays tax through it. Once per tax year, in one county only.
- When the notice arrives — County assessors mail notices of valuation “by around April 1 of each year” as § 7-38-20 requires, and the Department describes the net taxable value on that notice as the basis of the tax bill the treasurer sends later in the year. That notice is what starts your thirty-day clock.
- Property Tax Rebate for persons 65 or older — claimed at Section 3 of Form PIT-RC, filed with your New Mexico income tax return, by a resident who is 65 or older with modified gross income of $16,000 or less for 2025. It is separate from the value freeze and it runs on the tax-return calendar, not the assessor’s. Residents of Los Alamos, Santa Fe, Doña Ana and Bernalillo counties have a further Low Income Property Tax Rebate at Section 4, with a modified-gross-income limit of $24,000. Read at the Taxation and Revenue Department’s instructions for the 2025 PIT-RC, 13 August 2026.
The catch most senior-exemption roundups skip
Thirty days from a mailing, not a date you can diary a year ahead. § 7-36-21.3(B): “The application shall be filed no later than thirty days after the date of mailing by the assessor of the notice of valuation.” If you are away, or the notice goes to an old address, the window can close without you having seen it.
The freeze does not cover the things that usually raise your value. Subsection H excludes a change in valuation resulting from physical improvements made in the year before the tax year, a change in permitted use or zoning in that year, and a residential property in the first tax year it is valued. Add a room and the room comes in at current value.
Losing eligibility is a thing you must report, and the penalty is real. Subsection D requires notice to the assessor by the last day of February of the tax year after the year eligibility is lost — whether from a change in status, income or ownership. Subsection E: a person who knowingly claims a limitation they are not entitled to, or who fails to give that notice, “shall be liable for all taxes due, interest and a civil penalty of one thousand dollars ($1,000)”.
The income limit is a ratchet. Subsection F sets it at $35,000 multiplied by the consumer price index ending in the prior tax year over the index ending in 2019, rounded down to the nearest $100 — and then: “if the result would be an amount less than the corresponding amount for the preceding tax year, then no adjustment shall be made.” The limit can rise and can never fall. The index is the CPI for all urban consumers for the month ending September 30.
How to apply
File with your county assessor, on the application form the assessor furnishes (the Department designs it), within thirty days of the mailing of your notice of valuation. The form provides for proof of age or disability, occupancy and income eligibility. Ask the assessor for the current year’s income limit at the same time. The head-of-family exemption is claimed separately under § 7-38-17.
What we checked, so you can check us: we read the Taxation and Revenue Department’s own compilation of the Property Tax Code (3.6 NMAC, Rev. 05/20 — the statutes, the regulations and the constitutional appendices in one document) and its published assessor orders, this session. One honest limit on what is above: the income limit we publish is the 2025 one. Subsection G requires the Department to publish the calculated amount annually and give it to each assessor by December 1; when we read the Department’s orders page today, the newest limitation order posted was the one for tax year 2025. We publish the number the state has published rather than computing our own, and your assessor will have the current year’s figure.
Two things to check before you count on it
- Thresholds move. Age and income limits are reset by legislatures and are frequently indexed. Every figure above carries the year we confirmed it; confirm the current one before you budget around it.
- Your county or town may add its own. Statewide programmes are the floor. Counties and municipalities frequently run additional exemptions, and those are where a lot of real money sits.

Program classifications and thresholds are read from each state’s own revenue department, legislature or statute, at the source linked on the state page. Dollar and income thresholds change most years and are labelled with the year we confirmed them — check the current figure with the state or your county before relying on it.

Disabled Veteran Property Tax Relief in New Mexico: an Exemption Scaled to Your VA Rating
The New Mexico Department of Veterans' Services states both veteran property-tax exemptions in the general-information pages of DVS Form 1, revised March 2025.
- New Mexico does not run an all-or-nothing test: the property of a disabled veteran receives an exemption from taxable value equivalent to the veteran's VA service-connected disability rating, so a partial rating produces a partial exemption. The property must be occupied as the veteran's principal place of residence.
- A separate standard veteran exemption removes up to $10,000 of taxable value for a veteran or an un-remarried surviving spouse who is a New Mexico resident, and it reaches community or joint property of husband and wife.
- Eligibility for the disabled-veteran exemption turns on an honorable discharge plus a federal determination of service-connected disability by the United States Department of Veterans Affairs — the state defers to the VA finding rather than running its own medical test.
- A resident, un-remarried surviving spouse of a veteran who qualified for the disabled-veteran exemption is entitled to it even if the veteran never applied during their lifetime, which is the provision most often missed.
Before applying, match the rating letter, ownership, occupancy, survivor status, and filing timing in your records to the controlling text; confirm current filing instructions with the administering agency.
Compare veteran property-tax mechanisms across jurisdictions, then verify this state rule in the official source.
Deferral is the one relief type on this page that postpones the bill rather than reducing it, and secures the postponed amount against the home: New Mexico’s senior property-tax deferral works through the exact interest rate, the repayment triggers, and whether the lien outranks an existing mortgage.
