About Property Taxes in New Mexico
New Mexico property taxes are administered at the county level. Property is assessed at one-third (33.33%) of its market value — the lowest assessment ratio in the country. This means a $300,000 home has an assessed value of only $100,000 before exemptions. New Mexico's low assessment ratio combined with moderate mill rates results in effective property tax rates among the lowest in the western United States. Tax bills are mailed in the fall and due in two installments.
Payment & Assessment
New Mexico property taxes are paid in two equal installments: First half: Due November 10 Second half: Due April 10 of the following year A 1% per month penalty applies to late payments. Most counties offer online payment. Contact your county treasurer for payment options.
