The New Mexico Taxation and Revenue Department will conduct delinquent property tax auctions in Sandoval County on September 30, 2026, and Mora County on October 8, 2026. These auctions target properties with at least three years of unpaid taxes to recover state funds.
Why it matters
These auctions are held as a formal process to collect outstanding tax liabilities on real estate. While the state recovers the taxes owed, any proceeds exceeding the debt amount are remitted back to the former property owners.
Property owners must have at least 3 years of outstanding taxes to face an auction. Both the Sandoval and Mora County events are scheduled to begin at 10 a.m.

The details
To participate, prospective bidders must register in person at the venue starting at 8 a.m. on the day of the sale. Successful bids must be paid in full before the auction ends using certified funds such as a cashier's check, money order, or a personal check accompanied by a bank letter of credit.

The Mora County auction is scheduled for October 8, 2026, at 10 a.m.
Market Dynamics
These auctions represent the final phase of New Mexico's delinquent property tax collection statutes. This process ensures the state recovers its revenue while providing a mechanism to return excess proceeds to former owners in accordance with state law.
Prospective buyers must prepare specific payment methods, including a bank letter of credit, to ensure their bids are valid during the auction. Interested parties requiring assistance can contact the department at 505-827-0883.
The takeaway
These auctions serve as a last resort for the state to recover years of unpaid property taxes. Participants should ensure all financial documentation is ready before the 8 a.m. registration deadline to comply with state payment requirements.
