Property Tax Resources · Glasscock County, Texas
Permian Basin oil country with one of the lowest effective tax rates in Texas — Glasscock County’s 0.55% rate sits well below the state median, but mineral interests and energy valuations can produce unexpected bills.

🔴 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.
Glasscock County is one of the smallest and least populated counties in Texas, with fewer than 1,500 residents spread across 900 square miles of Permian Basin ranch and farmland centered on Garden City. The county sits directly in the core of West Texas oil production, and mineral interest valuations tied to Permian Basin activity can be volatile — fluctuating significantly as energy markets shift and production rates change.
At 0.55%, Glasscock County’s effective rate is among the lowest in Texas. But for mineral interest owners and working ranchers, the underlying value being appraised can move sharply in ways disconnected from actual income. If your mineral interest or surface valuation jumped with energy prices, the protest process applies to you just as it does to any suburban homeowner. Few owners protest in counties this small — which means errors compound quietly.

— Section 13, Declaration of Rights, Republic of Texas, 1836
Glasscock County is oil and ranch country — the kind of Texas that built the state’s wealth and gets little public attention. The founders of the Republic wrote their Declaration of Rights for exactly this kind of property owner: the person working land and mineral interests in a small county where government accountability is easy to overlook. A 0.55% rate sounds low, but on volatile Permian Basin valuations, the right to protest an inflated assessment is the same as anywhere else in the state. Look up your value. File your protest. The principle doesn’t shrink with the county’s population.
