Property Tax Protest · New Mexico
Protest your property taxes
in New Mexico.
New Mexico county assessors mail notices of value each spring, and a protest is filed directly with the assessor within 30 days of the mailing date. Unresolved cases are heard by the county valuation protests board, with a district-court refund claim as the alternative route. The state’s defining quirk protects long-term owners: residential valuation increases are capped at 3% per year, but the cap lifts when a home sells — so recent buyers routinely see values jump to full market and are the most common protesters. Boards decide on evidence of market value as of January 1, which is where a licensed appraisal — comparable sales, adjusted and documented — carries the petition.
Notices of value mail by April 1, and your protest petition is due 30 days from the mailing date — the notice states the exact day.
The 3% cap means neighbors in identical houses can legally carry very different taxable values (locals call the post-sale jump “tax lightning”), so comparing your value to a long-held neighbor’s proves little. Compare to the market instead.
The evidence
Boards act on value,
not frustration.
However New Mexico labels the process, the case underneath is identical: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal — comparable sales, documented adjustments, a signed opinion of value — is that showing. Start with the $5 check to see if the numbers are on your side before you spend real money.
- Valued as of your assessment date — not today
- Comparable sales with adjustments and citations
- Signed by a state-licensed NM appraiser
- Phone walkthrough — no stranger in your home
- Delivered in 48–72 hours, rush available

New Mexico questions
The 3% annual cap on residential increases resets at sale — locals call the jump “tax lightning.” The new value must still match January 1 market value, and that’s exactly what an appraisal tests.
30 days from the date your notice of value was mailed; notices go out by April 1. File the protest with the county assessor, and the county valuation protests board hears it if you don’t settle.
