🔴 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.
Gaines County anchors the southwest corner of the High Plains, where Seminole serves as the county seat for a community built equally on cotton farming and Permian Basin energy production. The county has seen significant oil activity in recent years as operators pushed west from the core Permian Basin — and that energy activity has pushed both land values and population higher, even as traditional agricultural operations face the same commodity price pressures that affect the whole region.
At a 1.57% effective rate, Gaines County property owners pay above the state median. Agricultural landowners should verify that productivity valuations are current and properly filed — energy-activity-driven land sales can inflate market values in ways that bleed into agricultural assessments if not challenged. More than half of owners who protested in 2024 achieved reductions.

— Section 13, Declaration of Rights, Republic of Texas, 1836Gaines County has built prosperity through two industries that require patience, capital, and acceptance of risk: farming and oil. The Republic’s founders understood that kind of ownership — property earned and maintained through hard work, protected from arbitrary exaction by the Declaration of Rights. When energy development raises land values that the agricultural operator doesn’t benefit from directly, and when the appraisal district captures that value without notice, the protest system is the correction mechanism the founders intended. Look up your value. File your protest. What you’ve built here is worth defending.
