Property Tax Resources · Reagan County, Texas
Big Lake and the Santa Rita No. 1 — Reagan County’s 0.81% effective rate falls on a small Trans-Pecos oil community where the first Permian Basin oil discovery in 1923 launched the energy empire that still defines West Texas.

Reagan County holds a place in Texas energy history that few communities can match: the Santa Rita No. 1 well, drilled near Big Lake in 1923, was the first commercial oil discovery in the Permian Basin — the find that opened the formation that now produces more oil than most countries. Big Lake is the county seat of a community that has lived with the Permian Basin’s cycles of boom and bust ever since, and mineral interests in the county carry significant historical and financial weight.
At 0.81%, Reagan County’s effective rate is below both the state and national medians. But for Permian Basin mineral interest owners whose production values may reflect peak-cycle assessments rather than current conditions, the protest process is still worth pursuing. Few protests are filed in counties this small. Your deadline is May 15, 2026.

“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, 1836Reagan County is where the Permian Basin began — the Santa Rita No. 1 changed Texas and the world in 1923, and the mineral interest owners in Big Lake carry that legacy. The founders of the Republic wrote that no property shall be taken without consent and just compensation. That principle protects the Reagan County royalty owner as fully as the West Texas ranch family. Look up your value. File your protest. The birthplace of the Permian Basin deserves fair assessment.
