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.

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