Karnes County lies in the heart of the Eagle Ford Shale play, one of the most prolific oil and gas formations in North America. Karnes City is the county seat for a community that experienced the full intensity of the Eagle Ford boom in the 2010s — rapid population influx, infrastructure pressure, and dramatic shifts in land and mineral values. The county’s median tax bill of $234 reflects extremely low residential property values, even as underlying mineral interests can be worth far more.
At 1.10%, Karnes County’s effective rate is above the national median — and for mineral interest owners whose production values were set during peak Eagle Ford activity, current assessments may not reflect the current production reality. The disconnect between low surface values and significant mineral wealth makes Karnes County one of the more complex appraisal environments in South Texas. More than half of those who protested in 2024 achieved reductions. 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, 1836Karnes County sits on one of the richest energy formations ever discovered in Texas, yet its surface residents live in communities with some of the lowest property values in the state. The founders of the Republic wrote that no property shall be taken without consent and just compensation — and for mineral interest owners whose royalty income has fallen while production-based appraisals remain elevated, the protest system is the statutory correction. Look up your value. File your protest. The Eagle Ford built this county’s revenue — its owners deserve fair treatment.
