When Are Property Taxes Due In New Mexico

If the November 10th due date falls on a weekend or holiday, the deadline is usually extended to the next business day. It is important for property owners to confirm the exact due date with their local county treasurer’s office, as there may be slight variations or specific local ordinances that affect payment timelines.

Payment Schedule and Penalties

Property taxes in New Mexico are generally billed once annually, with payments expected in full by the due date. However, some counties may offer installment payment plans or early payment discounts. Failure to pay property taxes by the due date will result in penalties, interest charges, and potentially tax lien sales.

The following outlines key dates and consequences related to property tax payments:

November 10: Standard due date for property tax payments.
November 11 onward: Penalties and interest begin to accrue on unpaid taxes.
March 1 (following year): Deadline for redemption before tax lien sales may occur.

Due Dates for Property Taxes in New Mexico

Property taxes in New Mexico are assessed and collected at the county level, which means the exact due dates may vary slightly depending on the county. However, the state sets specific deadlines for payment periods that apply statewide.

The primary deadlines for property tax payments in New Mexico are as follows:

First Half Payment Due Date: March 10
Second Half Payment Due Date: October 10

These dates correspond to the semi-annual property tax billing cycle. Property owners have the option to pay their taxes in two installments or pay the full amount by the first due date.

Semi-Annual Payments: Pay half by March 10 and the remaining half by October 10.

Late Payment Period	Penalty	Interest
After March 10 (First Half)	10% of unpaid tax	1.5% per month on unpaid balance
After October 10 (Second Half)	10% of unpaid tax	1.5% per month on unpaid balance

It is important for property owners to contact their county treasurer’s office if they anticipate difficulty paying on time, as some counties may offer payment plans or other assistance programs.

County Variations and Additional Considerations

While the March 10 and October 10 deadlines are standard across New Mexico, counties may have unique processes and minor timing differences for mailing tax statements or processing payments. Key points to consider include:
