Deadlines and Key Dates
Deadlines and Key Dates
Missing a key deadline is one of the most common — and costly — mistakes in the property tax protest process. Below are the most important dates New Mexico property owners need to know to file a protest successfully. These dates are notional and vary from county to county in NM.
May 1
Assessment notices mailed by counties
Review your Notice of Value carefully. This document determines your home’s taxable value and starts the clock for your protest window.
June 2
FINAL DEADLINE to file protest
Your written protest must be filed by the later of April 1 of the property tax year, or 30 days after the mailing of a notice of value. No exceptions — missing it means waiting another year.
June 2 through October 17
Hearings/conferences scheduled and conducted
After a protest has been set for hearing, or if a taxpayer requests or has requested an informal conference, the assessor may schedule and hold such a conference before the date of the hearing.
October 30
Final decisions and tax bills sent
Once protests are heard and values finalized, new tax bills are calculated and mailed.
