Property Tax Resources · Brewster County, Texas
Texas’s largest county by area — Big Bend country, Marfa mystique, and an Alpine real estate market that has surprised long-time locals with its pace of change.
🔴 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.
Brewster County is the largest county in Texas by area, spanning more than 6,000 square miles of Chihuahuan Desert, the Chisos Mountains, and Big Bend National Park. The county seat of Alpine anchors Sul Ross State University and serves as the commercial center for a region that draws artists, retirees, and Marfa visitors in numbers that have noticeably moved property values over the past decade. Rural ranchland makes up the majority of the county’s acreage, with agricultural use valuations applying to many large tracts.
The Brewster County Appraisal District is a small operation serving a geographically enormous county. If your property value increased by $1,000 or more from the prior year, you should have received a reappraisal notice — and you have the right to protest it informally with the district before requesting a formal ARB hearing. If you purchased your property recently, the CAD will almost always reduce the appraised value to your actual purchase price if you provide a closing statement.

An appraiser at the CAD will review your value and contact you to try to reach an agreed value. This informal step resolves many protests without a 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.”

Brewster County is some of the most rugged, most beautiful land in North America — and it has been home and working land to Texas families for generations. The surge of outside interest in the Big Bend and Marfa region has driven appraisals beyond what local landowners can recognize as their reality. The founders built this Republic on the principle that no man’s property shall be taken without consent. That applies at the foot of the Chisos the same as it does anywhere in Texas. Show up. Look up your value. File your protest. Attend the hearings. The people setting these rates are your neighbors. They work for you — as long as you hold them to it.
