How it works
How to protest your property taxes in New Mexico.
- Step 1
Check your savings
Enter your address and pay $5. We check your New Mexico assessment against recent nearby sales.
- Step 2
Order the appraisal
A desktop appraisal valued as of your assessment date, with the $5 credited. Complex homes get one exact quote.
- Step 3
Show us your home
Walk through on your phone so the appraiser sees its condition. A desktop appraisal needs no visit.
- Step 4
File your protest
A state-licensed NM appraiser signs it, with a cover letter and filing steps. You file by your deadline, and the county valuation protests board hears your case.
The evidence
Boards act on value, not frustration.
However New Mexico labels the process, the case underneath is the same: show what your home was actually worth on the assessment date. A licensed, USPAP-compliant appraisal, with comparable sales, documented adjustments and a signed opinion of value, is that showing.

- A phone walkthrough; a desktop appraisal needs no visit

The process
How New Mexico handles protests.
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.
Worth knowing in New Mexico
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.
FAQ
New Mexico questions
Why did my value jump right after I bought my New Mexico home?
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.
How long do I have to protest in New Mexico?
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.
