Property taxes on vacant land in New Mexico

Why the bill on raw land is usually small, how it is figured, when it is due, and what happens when it is not paid.

Property tax on vacant land in New Mexico is usually one of the smallest bills you will ever get for owning something — often tens of dollars a year on a small rural lot — but it is the one bill that can cost you the land if ignored.

How it is figured

The county assessor sets a value. The taxable value is one-third of that. The tax is that taxable value times the local mill rate, which is set each year by the county and the districts inside it (schools, hospitals, water conservancy) and varies by where the land is. So two identical lots in different districts pay different amounts; the treasurer's search for the exact UPC is the only way to know the real figure. Our listings link straight to it and never print a tax number of their own.

Why raw land is cheap to hold

Assessed values on rural vacant land are low, and there is no building. A lot that sells for a few thousand dollars can be assessed lower still. Expect tens of dollars a year on a small lot, more on larger or better-located acreage.

When it is due

Bills go out in the fall. The tax may be paid in two halves — the first by early December, the second by early May — or all at once. The treasurer's site takes cards for most counties.

If it is not paid

Interest and penalties accrue. Once a property is three or more years delinquent the county hands it to the state's Property Tax Division, which sells it at a public auction to recover the taxes. That is where some of the land we buy comes from; it is also why every listing of ours has a treasurer link — so you can see for yourself that nothing is owed.

During a contract for deed

Our contracts make the yearly tax the buyer's from the day of signing, as is usual. We forward the bill or you pay the county directly; an unpaid bill is a default under the contract, so it is worth setting a reminder.

After you own it

The bill comes to the mailing address on the assessor's record. Update it when you move; the county does not chase, and "I never got the bill" does not stop the clock.
