New Mexico Homestead Exemption: Amount, Filing & Savings
New Mexico’s property-tax homestead benefit is the head-of-family exemption. It takes up to $2,000 off the taxable value of residential property owned by a New Mexico resident who heads a family (NMSA 7-37-4). You claim it with the county assessor within 30 days after the notice of valuation is mailed; it then carries over automatically while ownership and eligibility stay the same. A separate law, NMSA 42-10-9, shields $150,000 of a primary residence from judgment creditors, a figure subject to cost-of-living adjustment under NMSA 42-10-14.
Head-of-family exemption: $2,000 of taxable value
New Mexico taxes a share of value, not the full value: “The tax ratio is thirty-three and one-third percent” (NMSA 7-37-3). The head-of-family exemption comes off that taxable figure. NMSA 7-37-4 sets it at $2,000 “for the 1993 and subsequent tax years,” deducted “from taxable value of property to determine net taxable value.” The home can be owned directly or “held in a grantor trust” under Internal Revenue Code sections 671–677, by a head of a family who is a New Mexico resident.
“Head of a family” is defined in 7-37-4(D). A resident qualifies as any one of the following:
- “a married person, but only one spouse in a household may qualify as a head of a family”;
- “a widow or a widower”;
- “a head of household furnishing more than one-half the cost of support of any related person”;
- “a single person, but only one person in a household may qualify as a head of family”; or
- “a member of a condominium association or like entity who pays property tax through the association.”
The exemption is allowed “only once in any tax year” and “in only one county,” even if you own property in several counties.
Deadline, renewal and when to notify
County assessors mail notices of valuation “By April 1 of each year” (NMSA 7-38-20). Under NMSA 7-38-17(C), an exemption that must be claimed “shall be applied for no later than thirty days after the mailing of the county assessor’s notices of valuation … in order for it to be allowed for that tax year.” If your claim is still pending at that point, you can file a protest under 7-38-21, and the assessor decides within the protest period.
After the first year, you do not refile. Head-of-family and veteran exemptions “need not be claimed for subsequent tax years if there is no change in eligibility for the exemption nor any change in ownership.” Assessors apply them “automatically.” If you lose eligibility, for example by selling, you must tell the assessor “by the last day of February of the tax year immediately following the year in which loss of eligibility occurs.” Intentionally claiming and receiving an exemption you are not entitled to, or failing to give that notice, is a misdemeanor with a fine of up to $1,000 (7-38-17(G)).
The 3% valuation limit and the low-income freeze
These two programs limit the assessed value itself, not the tax rate.
Under NMSA 7-36-21.2, residential value in a tax year may not exceed “the higher of one hundred three percent of the value in the tax year prior … or one hundred six and one-tenth percent of the value in the tax year two years prior.” No application is needed, but three things fall outside the limit:
- “a residential property in the first tax year that it is valued for property taxation purposes”;
- “any physical improvements, except for solar energy system installations, made to the property during the year immediately prior to the tax year or omitted in a prior tax year”; and
- any tax year after “a change of ownership of the property occurred in the year immediately prior,” or after the use or zoning changed in the prior year.
After a purchase, the home is revalued at “current and correct value.” Subsection E lists eight transfers that are not treated as a change of ownership.
A tighter freeze covers a single-family dwelling “owned and occupied by a person who is sixty-five years of age or older or disabled” whose modified gross income for the prior taxable year did not exceed “the greater of thirty-five thousand dollars ($35,000)” or that figure indexed to the consumer price index each year (NMSA 7-36-21.3). “Disabled” means blind or permanently disabled “with medical improvement not expected” under the federal Social Security Act (42 U.S.C. 421), or a permanent total disability under New Mexico’s Workers’ Compensation Act. The value is held at its level in the tax year the owner qualifies and files an application. The Torrance County Assessor’s 2026 application lists the indexed ceiling as $44,200 of household modified gross income. You file on the assessor’s application form no later than 30 days after the assessor mails the notice of valuation. After you file proof of income eligibility “for the three consecutive years immediately subsequent to the tax year for which the application is made,” the assessor applies the freeze automatically until eligibility changes. Physical improvements made in the prior year, a change in permitted use or zoning in the prior year, and a home’s first valued year are not frozen. If you lose eligibility through a change in status, income or ownership, you must tell the assessor “by the last day of February of the tax year immediately following the year in which loss of eligibility occurs.” A person who knowingly violates the section “by intentionally claiming and receiving the benefit of a limitation to which the person is not entitled,” or who fails to give that notice, is liable for all taxes due, interest and “a civil penalty of one thousand dollars ($1,000).”
Veterans and disabled veterans after the 2025–2026 changes
The veteran exemption in NMSA 7-37-5 was “four thousand dollars ($4,000)” for tax years 2006 through 2024 and “ten thousand dollars ($10,000)” for tax year 2025. For 2026 and later, it is the $10,000 figure “adjusted for inflation,” rounded down to the nearest $100. The Taxation and Revenue Department publishes the figure and sends it to assessors “no later than December 1 of the prior tax year.” A “veteran” was honorably discharged and served “on active duty continuously for ninety days.” Shorter service counts if the discharge was “brought about by service-connected disablement.” The exemption also covers an unmarried surviving spouse.
The disabled veteran exemption in NMSA 7-37-5.1 is no longer limited to a 100% rating. Laws 2025, ch. 10 made it proportional “to the 2026 and subsequent property tax years.” The exempt share equals “the percentage of the veteran’s disability as determined by federal law multiplied by the taxable value of the property” after the regular veteran exemption. The veteran must occupy the home “continuously as the veteran’s principal place of residence.” A surviving spouse’s property is exempt if the couple were married when the veteran died and the spouse keeps living there. Where two disabled veterans own the same property, the highest rating is used. Claims need a certificate of eligibility from the Department of Veterans’ Services, filed with the county assessor (7-38-17(E)).
Income-tax rebate for residents 65 and older (NMSA 7-2-18)
NMSA 7-2-18 lets a resident who has reached 65, files an individual New Mexico income tax return and “is not a dependent of another individual” claim a rebate of the property tax due on the principal place of residence above the amount in a statutory table based on modified gross income. Renters qualify too: their property tax is figured as six percent of the gross rent for the year. The principal place of residence includes up to five acres of land reasonably necessary for use of the dwelling as a home. No rebate is allowed to anyone who was an inmate of a public institution for more than six months of the year, or who was not physically present in New Mexico for at least six months of it. The rebate “shall not exceed two hundred fifty dollars ($250) per return,” or $125 on a separate return that could have been filed jointly. It is not allowed if modified gross income exceeds “sixteen thousand dollars ($16,000),” or $25,000 in a county whose commissioners adopted the higher table by resolution. The rebate is taken against New Mexico income tax, and any excess is refunded.
Creditor homestead: $150,000 under NMSA 42-10-9
Laws 2023, ch. 104 rewrote the creditor homestead for “actions filed on or after July 1, 2023.” NMSA 42-10-9 now reads: “A person shall have a homestead exemption in a domicile or land owned by the person that is the primary residence of the person.” The protection runs against “attachment, execution or foreclosure by a judgment creditor,” bankruptcy and insolvency trustees, and probate executors. The amount is “one hundred fifty thousand dollars ($150,000).” That figure, the $300,000 figure and the $15,000 in-lieu amount below are subject to NMSA 42-10-14: “On July 1, 2025, and at each two-year interval” they “shall be adjusted to reflect the change in the consumer price index,” the Administrative Office of the Courts publishes any adjustment, and an adjustment does “not apply to legal proceedings commenced prior to the date of such adjustments.” The Supreme Court’s claim-of-exemption form (Form 4-803 NMRA, as amended effective December 31, 2024) still prints $150,000. It rises to $300,000 “if the spouse of the person claiming the exemption died within two years prior to the date of claiming the homestead exemption,” provided the deceased spouse could have claimed it. “Domicile” includes “a mobile home, trailer, recreational vehicle, outbuilding or other similar shelter,” whether or not it meets building codes. The section “shall be liberally construed in favor of the person claiming.”
The homestead does not reach every debt:
- 42-10-9(E): “The provisions of this section shall not apply to garnishment or properly perfected liens of secured creditors.”
- 42-10-11: the article does “not apply or extend to taxes, garnishment, recorded liens of mortgagees or lessors or recorded liens of laborers or materialmen for labor or materials furnished for the construction or repair of the dwelling house.”
- 42-6-11: when a co-owner wins a suit to establish title to jointly owned real estate for the benefit of all owners, the suit’s reasonable expenses and attorney’s fees become a lien on the other co-owners’ shares, and that real estate is not “exempt from said charge or lien by virtue of any execution or forced sale exemption law in force in this state.”
There is no declaration to record in advance. The filing sections that once existed (42-10-8 and 42-10-12) were repealed in 1979. You raise the exemption in the court case: under 42-10-13, a claim of exemption is filed “in the appropriate court,” and the time allowed to file it “shall not be less than ten days after the filing of a writ of execution.” The creditor must give you a notice that “shall contain a complete list of exemptions provided by the law.” If a judgment creditor instead sues to foreclose its judgment lien on the home (NMSA 39-4-13), NMSA 39-4-15 requires you to “set up [your] claim of exemption by answer in such foreclosure suit.” A resident who owns no homestead gets $15,000 of real or personal property “in lieu of the homestead exemption” (42-10-10).
New Mexico owners ask
I bought my house in June. Can I get the head-of-family exemption this year?
Only if your claim was in within 30 days after the assessor mailed that year’s notices of valuation, which go out by April 1. Otherwise file for next year. After that, the exemption carries over automatically until ownership or eligibility changes.
Do my spouse and I each get $2,000?
No. Under 7-37-4(D)(1), “only one spouse in a household may qualify as a head of a family.” The exemption applies once per tax year, in one county.
My house is in a living trust. Do I lose the exemptions?
Not if it is a grantor trust under IRC 671–677. The head-of-family, veteran and disabled veteran sections each name property “held in a grantor trust.” A transfer to a revocable trust benefiting you, your spouse or a child is not a change of ownership for the 3% limit.
Does the $150,000 homestead stop a foreclosure by my lender?
No. Recorded mortgage liens and “properly perfected liens of secured creditors” are outside it (42-10-9(E), 42-10-11). It protects against judgment creditors.
