The first half payment is due November 10th and must be paid by December 10th to avoid delinquent charges. Second half payments are due by April 10th of the following calendar year and must be made by May 10 or the first business day thereafter to avoid delinquent charges. You will only receive one bill and no additional notice for the 2nd half installment.

If you have not received your tax bill by November 15th, call us at 575-835-0714 for help.

Delinquent Taxes

If your taxes become delinquent, by State law (7-38-15 NMSA 1978), each June the County will mail a delinquency notice to the assessed property owner for any tax bill 30 or more days delinquent. The notice will inform the owner that if the taxes on real property, including penalty and interest charges, are not paid within two years from the date of delinquency, the property will be sold at state public auction. For owners of mobile homes and personal property, the notice will state that the property is subject to seizure and subsequent sale after six months from the date of delinquency.

Q: What can I do if my delinquent taxes have been transferred to the New Mexico State Property Tax Division for collection?
A: Once taxes have been transferred to the Division for collection, all delinquent taxes, penalties, interest, and costs must be paid in full or your property may be offered for sale at public auction. If a property owner is unable to pay in full, the owner may prevent the sale of the property by entering into an Installment Agreement with the State Property Tax Division for payment on all outstanding liabilities.

Q: I have been contacted by the New Mexico State Property Tax Division and informed that my property will be sold at public auction. I owe back taxes for prior years. May I just pay the oldest delinquent tax to prevent the sale of the property?
A: Real property owners who owe three or more years of prior taxes will have their property sold by the State unless delinquent taxes, interest and penalty charges for all years are paid in full by the date of the sale of the property (4-38-65-NMSA 1978).

Delinquent Tax Property Sales

Q: How can I obtain a listing of properties that may be sold for delinquent taxes?
A: All tax sale lists must be published in a newspaper of general circulation for three weeks preceding the week of the sale.
