What Happens If I Don't Pay Property Taxes in New Mexico?

Failing to pay your property taxes in New Mexico means your home can be subject to a tax lien, giving the county the legal right to initiate a tax sale. Through this process, local authorities may auction off the property to recover unpaid taxes, penalties, and fees. The buyer at the tax sale gets ownership of the property, and you won't get the opportunity to get it back by redeeming it.

In this article, you'll learn about the New Mexico property tax sale process, delinquent tax timelines, tax lien enforcement, and steps to avoid losing your home in a tax sale.

When Are Property Taxes Due in New Mexico?

In New Mexico, the first half of property taxes are due November 10, and delinquent after December 10. The second half is due April 10, and becomes delinquent after May 10. Delinquent tax notices are mailed in June for unpaid balances. (N.M. Stat. § 7-38-38, § 7-38-51 (2025).)

What Are the Penalties and Interest for Delinquent Property Taxes in New Mexico?

A penalty of 1% of the delinquent tax amount is charged for each month or portion of the month the taxes remain unpaid, with a maximum penalty of 5% of the delinquent taxes. (N.M. Stat. § 7-38-50 (2025).)

What Is a Tax Lien and How Does It Affect Me in New Mexico?

People who own real property must pay property taxes. The government uses these taxes to pay for schools, public services, libraries, roads, parks, and the like. Typically, the tax amount is based on a property's assessed value. When homeowners don't pay their property taxes, the overdue amount becomes a lien on the property. A lien effectively makes the property act as collateral for the debt. All states have laws that allow the local government to sell a home through a tax sale process to collect delinquent taxes.

So, if you don't pay your real property taxes in New Mexico, the county can eventually sell your home to a new owner at a tax sale, and you won't be able to get it back afterward. However, you'll have plenty of time to get current on the delinquent amounts before a sale occurs. And if a problem occurred in the sale process, you might be able to invalidate the sale and recover your property.

Tax Delinquency Timeline: How Long Before Your Property Faces a Tax Sale?

If your New Mexico property taxes are delinquent for more than two years, your home will be added to a "tax delinquency list." (N.M. Stat. § 7-38-61 (2025).)

Three years after the first delinquent date shown on the list, the Taxation and Revenue Department will schedule a sale to sell your home to pay off the tax debt. (N.M. Stat. § 7-38-67 (2025).)

Notice Requirements for New Mexico Property Tax Auctions

New Mexico's Taxation and Revenue Department must mail you a notice about the upcoming tax sale and publish notice in a newspaper.

• Notice by mail. The Department must send you a notice by certified mail, return receipt requested, at least 20 days, but not more than 30 days, before the tax sale date. The notice will inform you how much you must pay in taxes, penalties, interest, and costs to get current on the debt. (N.M. Stat. § 7-38-66 (2025).)
• Notice by publication. In New Mexico, notice of the sale must be published in a local newspaper for three weeks or, if the area doesn't have a newspaper, in a newspaper published in a nearby county. (N.M. Stat. § 7-38-67 (2025).)

What Happens During a New Mexico Property Tax Auction?

The tax sale consists of a public auction where the Department sells the home to the highest bidder. After the sale, the purchaser gets a deed (title) to your home and becomes the new owner. (N.M. Stat. § 7-38-70 (2025).)

The minimum price at the sale can't be less than the total amount of all delinquent taxes, penalties, interest, and costs. (N.M. Stat. §§ 7-38-67, 7-38-70 (2025).)

Sometimes, the Department will agree to sell only part of the property to cover the delinquent taxes, penalties, interest, and costs, like if your property can be divided and you agree to this arrangement. (N.M. Stat.§ 7-38-67 (2025).)

Stopping a New Mexico Tax Sale: Redeeming Your Property Before the Auction

You can stop the sale by paying the delinquent taxes, penalties, interest, and costs by 5:00 p.m. of the day before the sale. (N.M. Stat. § 7-38-66 (2025).) This payoff is called "redeeming" the property.

Property Tax Payment Plans

Or you may enter into an installment agreement by 5:00 p.m. of the day before the sale. (N.M. Stat. § 7-38-66, § 7-38-68 (2025).) The installment agreement can't extend for longer than 36 months, and interest will accrue at 1% per month. (N.M. Stat. § 7-38-68 (2025).)

But the tax sale may proceed if you:

• don't make the installment payments on or before the dates specified in the agreement
• fail to pay any other property taxes when due, or
• fail to meet any other condition contained in the agreement. (N.M. Stat.§ 7-38-68 (2025).)

Also, if you previously entered into an installment agreement to pay the delinquent taxes and failed to meet your obligations under that agreement, you can't do another one. So, for example, if you previously defaulted on an installment agreement, you won't be eligible to enter into another contract to get caught up on the delinquent amounts. (N.M. Stat. § 7-38-68 (2025).)

Is There a Redemption Period After a Tax Sale in New Mexico?

In some states, a homeowner who loses their home to a tax sale can get the house back by catching up on the delinquent amounts or by paying the purchaser the amount paid at the sale, plus some other amounts. This process is also called "redeeming the home."

In New Mexico, however, you can't redeem your home after a tax sale.

Getting Your Home Back By Challenging the Tax Sale

While New Mexico law doesn't have a law giving you the right to redeem after the sale, you might be able to get your home back following a tax sale by challenging the sale in court. (N.M. Stat. § 7-38-70 (2025).)

You'll have to show:

• your property wasn't subject to taxation for the tax years claimed
• the Department failed to mail the notice before the sale or didn't receive any required return receipt
• you had paid all delinquent taxes, penalties, interest, and costs before the sale, or
• you entered into an installment agreement to redeem the home before 5:00 p.m. on the day before the sale, but the sale went ahead anyway. (N.M. Stat. § 7-38-70, § 7-38-65 (2025).)

You must file such a suit within the two years after the sale. (N.M. Stat. § 7-38-70 (2025).)

How Property Tax Sales Affect Your Mortgage in New Mexico

Property tax liens have priority. So, a tax sale process can eliminate mortgages (and deeds of trust). If your mortgage loan isn't escrowed and you don't pay the property taxes, the loan servicer will usually pay them to stop a tax sale from happening.

Most mortgages say the lender can add the amount it paid for the taxes to your loan. You'll then have to make repayment arrangements with the servicer or potentially face a foreclosure.

What Options Do I Have If I Can't Afford to Pay My Property Taxes in New Mexico?

If you're having trouble paying your property taxes, you might be able to reduce your tax bill or get extra time to pay. New Mexico provides several property tax relief options, including exemptions, rebates, deferrals, and specific help for veterans, low-income, elderly, and disabled residents. Deadlines to apply for these programs vary by county and program, so contact your local assessor's office to find out about what alternatives might be available to you.
