Knox County sits in the Rolling Plains of Northwest Texas, where Benjamin serves as the county seat for a community of ranchers and dryland cotton and wheat farmers. The county’s small population of roughly 3,500 residents reflects decades of agricultural consolidation and rural outmigration that has left large landholdings in the hands of a shrinking number of operators. The county has limited commercial activity and few non-agricultural comparable sales for the appraisal district to work from.
At 1.16%, Knox County’s effective rate exceeds the national median. For dryland cotton and grain farmers, verifying that productivity valuations are accurate — rather than based on thin comparable sales data that may not reflect current market conditions — is the most important step. Few protests are filed in counties this size. Your deadline is May 15, 2026.

Before your ARB hearing, a CAD appraiser may offer to settle. Review any offer carefully — you can accept or proceed to the formal hearing.
The Appraisal Review Board is independent of the CAD. Present your evidence clearly and concisely. Most hearings run 15–30 minutes.
Disagree with the ARB ruling? You may appeal to district court, binding arbitration, or SOAH (properties over $1 million).
“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, 1836
Knox County cotton farmers have planted and harvested on Rolling Plains soil for generations, operating businesses that depend on rainfall, commodity prices, and patience. The founders of the Republic wrote that no property shall be taken without consent and just compensation — and for a dryland farmer whose land is appraised at values divorced from what the land actually produces, the protest system is the statutory correction. Look up your value. File your protest. Rolling Plains agriculture deserves accurate assessment.
