🔴 2026 Protest Deadline: May 15, 2026 — or 30 days after your Notice of Appraised Value is mailed, whichever is later. Miss this date and you waive your right to protest.

Dallam County occupies the far northwest corner of Texas — the only Texas county to border two other states, sharing lines with both Oklahoma and New Mexico. Dalhart, the county seat, lies at the crossroads of U.S. Highways 54, 87, 287, and 385. The county’s economy runs on cattle feedlots, farming, and wind energy. Population has grown steadily since 2010, bucking the trend of rural Texas decline.

With a median tax rate near 2% and median bills around $1,640, Dallam County property owners pay more than many rural Texas counties. Annual protests remain the primary tool for keeping assessments honest — and Texas law gives every property owner the right to file at no cost.

How to Protest Your Dallam County Property Taxes

1

Look Up Your Value

Search your account at dallamcad.org. Know your Notice of Appraised Value and the deadline printed on it.

2

File Your Protest

File online, by mail, or in person at Dallam Appraisal District: 401 Denver Ave., Dalhart, TX 79022. Deadline: May 15, 2026 or 30 days after notice was mailed.

3

Gather Your Evidence

Recent sales of comparable properties, your purchase price, photos of condition issues, and repair estimates all strengthen your case.

4

Try Informal Resolution

Before your ARB hearing, a CAD appraiser may offer to settle. Review any offer carefully before accepting.

5

Present to the ARB

The Appraisal Review Board is independent of the CAD. Present your evidence clearly and concisely. Most hearings run 15–30 minutes.

6

Appeal If Needed

Disagree with the ARB ruling? You may appeal to district court, binding arbitration, or SOAH (properties over $1 million).

“No person’s particular services shall be demanded, nor property taken or applied to public use, unless by the consent of himself or his representative, without just compensation being made therefor.”

— Section 13, Declaration of Rights, Republic of Texas, 1836

Dallam County is where Texas meets the rest of the West — the corner of two states, the edge of the High Plains, a place built by farming families and cattle operations that have been here for over a century. The same principle the founders wrote into the Republic’s founding document applies just as much at the Texas-Oklahoma-New Mexico tripoint as anywhere else in the state. Look up your value. File your protest. Show up to the public hearings. The people setting your rates work for you.
