New Mexico property tax exemptions
✓ Verified August 2026 against official county pages — 3 sources linked below.
Exemptions lower the value your taxes are figured on — for most homeowners they're the easiest money on this page. Nearly every one has a filing date, though, and missing it usually costs you a year. The statewide programs and their deadlines are below; many counties and cities layer their own versions on top.
| Exemption | Deadline to file | What it's worth |
|---|---|---|
| Head-of-family exemption | Claim with the county assessor (within the protest window after a purchase) | A modest taxable-value exemption for New Mexico resident heads of household — small, but free and renewable |
| Veteran exemptions | Claim with the county assessor with your NMDVS certificate | Expanded by 2024 constitutional amendments: a larger base exemption for honorably discharged veterans and a disability-scaled exemption up to full exemption at 100% — amounts index going forward |
| 65+/disabled low-income valuation freeze | Apply with the county assessor (three consecutive annual filings make it permanent in most counties) | Freezes the taxable value for homeowners 65+ or disabled under the state income limit |
65 or older?
Start with the 65+/disabled low-income valuation freeze — Freezes the taxable value for homeowners 65+ or disabled under the state income limit. Deadline: Apply with the county assessor (three consecutive annual filings make it permanent in most counties).
Comparing states? Every state's senior program is in the senior property tax exemptions by state table.
How to file
Head-of-family exemption: One-time claim; reapply after ownership changes.
Veteran exemptions: Certify eligibility with the NM Department of Veterans Services, then file with the assessor.
65+/disabled low-income valuation freeze: File with income documentation during the spring window.
Amounts and dates above are the statewide baseline — where counties or cities run their own versions, the local deadline and paperwork can differ. Confirm with your county assessor before relying on a date.
Exempted and still think the bill is high? The next lever is the value itself: how to appeal in New Mexico.
