New Mexico Seniors 65 and Older May Qualify for Property Tax Rebates

George Chandler, the Los Alamos County Assessor, and the New Mexico Taxation and Revenue Department are sitting on a program that paid out a combined $10,236 in property tax relief to all qualifying county residents last year, a figure so modest for a county of roughly 20,000 people that it almost certainly means hundreds of eligible households never filed a claim. Two separate rebate programs are available on 2025 New Mexico personal income tax returns right now: one for all New Mexico seniors 65 and older and one for low-income property owners specifically in Los Alamos, Santa Fe, and Doña Ana counties. For seniors in Los Alamos County who qualify for both, the combined maximum reaches $600 on a single return.

Two Programs, One Return

New Mexico's property tax relief for older and lower-income homeowners runs through two parallel tracks. The first is the statewide Property Tax Rebate for Persons 65 or Older, which rebates a portion of property tax paid on your principal residence, up to a maximum of $250 for single filers or $125 for married taxpayers filing separately. The second is the county-specific Low-Income Taxpayer Property Tax Rebate, a program that the Los Alamos County Council extended through 2028 with an ordinance adopted in January 2025. That county program offsets a sliding-scale percentage of property tax, not to exceed $350 for single filers or $175 for married filers filing separately. Both can be claimed on the same New Mexico Rebate and Credit Schedule, known as the PIT-RC, when filing your 2025 state personal income tax return.

Los Alamos County has participated in the county rebate program continuously since 2001, renewing its authorization every four years. The current ordinance, adopted under Section 7-2-14.3 of the New Mexico Statutes, runs through the 2028 tax year. Each year, the county reimburses the New Mexico Taxation and Revenue Department directly for every dollar paid out to qualifying county residents, a financial commitment the County Council has maintained for more than two decades.

Who Qualifies for the State 65+ Rebate

Qualifying for the statewide senior rebate requires meeting four conditions:

• You must be a New Mexico resident who was physically present in the state for more than six months of the tax year.
• You must be age 65 or older on the last day of the tax year.
• The property must be your principal residence, and any surrounding land may not exceed five acres.
• The property must be subject to property tax; tax-exempt properties do not qualify.

The income threshold is where Los Alamos County residents gain an important advantage. For most New Mexico seniors, the modified gross income ceiling for the prior tax year is $16,000. Residents of Los Alamos, Doña Ana, and Santa Fe counties benefit from a higher limit: modified gross income below $24,000 for the prior tax year, according to AARP Foundation eligibility guidance. The maximum rebate remains $250 for single filers and $125 for married filers filing separately.

Who Qualifies for the County Low-Income Rebate

The county program carries no age requirement at all. Any low-income homeowner whose principal residence is in Los Alamos County may apply, regardless of age. The income ceiling is a modified gross income of $24,000 or lower, with the percentage of relief calculated on a sliding scale. The property must be subject to property tax, and only your principal residence qualifies; the five-acre surrounding land limit applies here as well.

The Sliding Scale: Your Potential Rebate

The county rebate is not a flat credit. It pays back a percentage of your actual property tax bill, with that percentage dropping as income rises. The full scale from the County Council's ordinance:

The rebate may not exceed $350, no matter the calculated percentage. Los Alamos County homeowners pay an average of $2,442 in annual property taxes on median home values of $412,700, according to property tax analysis firm Abode Money, which puts the effective rate at 0.59 percent. At 35 percent, even the lowest rebate bracket would yield roughly $854 against that average bill, but the $350 hard cap applies universally.

How to Claim: Step-by-Step

A Separate Program: The Property Tax Freeze

Los Alamos County seniors should also know that a third, distinct program exists: the property tax freeze, which locks in assessed value rather than providing a direct cash rebate. The freeze carries its own rules. Only single-family dwellings are eligible, applicants must own and occupy the property as their primary residence, and applicants must be either disabled or have turned 65 during the year of application. The income limit for the 2025 freeze was a modified gross income of $42,900 or less in 2024, with that ceiling adjusted annually for inflation. The freeze is separate from both rebate programs described above, and eligibility conditions for all three programs should be confirmed directly with the Taxation and Revenue Department.

Where to Get Help

For eligibility questions, current income thresholds, and the PIT-RC form, call the New Mexico Taxation and Revenue Department's taxpayer assistance line at 1-866-285-2996. The TRD also accepts appointments at its offices and publishes updated filing instructions online. For questions specific to Los Alamos County's program terms or the January 2025 ordinance, contact George Chandler at the Los Alamos County Assessor's Office at (505) 662-8030; Chandler holds in-person office hours every Monday from 9 a.m. to noon.

The AARP Foundation Tax-Aide program offers free return preparation assistance to eligible seniors and can help identify which rebate lines apply on the PIT-RC. Any taxpayer who already filed their 2025 return without claiming these credits should consult a tax professional about filing an amended return before the window closes. The $10,236 paid out to all eligible Los Alamos County residents last year is a signal: the program works, and it is waiting to be used.
