McKinley County property tax appeals
Your deadline runs from the date on your assessment notice.
Appeals go to McKinley County Valuation Protest Board.
New Mexico's 3 percent residential cap resets after qualifying ownership changes, so the comp engine must stay off.
- The current and correct value is below the capped value.
- The notice has a classification, exemption, or property-record error.
- The 3 percent cap already holds value below market.
- You miss the 30-day notice window.
Read the full explanation
New Mexico generally limits annual increases in a residential property's value to 3 percent, but the limit does not apply after a qualifying change of ownership, a change of use or zoning, or certain improvements. A property owner may protest the notice of value with the county assessor within 30 days after it is mailed. Because capped value can sit below current market value, an appeal often will not lower the bill unless the appeal can reduce value below the cap or correct another error. This is general information, not tax advice.
