New Mexico Property Tax Relief for Seniors 2026

Every statewide property tax break New Mexico offers older homeowners that we could confirm on an official page: the type of relief, the age and income limits, the amount, how to apply and the deadline.

New Mexico has no age-based homestead exemption. Its main property tax relief for seniors is a valuation freeze for homeowners aged 65+ (or disabled) with prior-year household modified gross income under $44,200 for tax year 2026. Homeowners or renters aged 65+ with income of $16,000 or less can also claim an income-tax property tax rebate of up to $250, and low-income residents of Los Alamos, Santa Fe, Doña Ana and Bernalillo counties with income of $24,000 or less can claim an extra rebate of up to $350 with no age requirement (both tax year 2025). No statewide senior property tax deferral program was found in official sources. (sources)
