🔴 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.
Guadalupe County has been one of the fastest-growing counties in Texas for over a decade, anchored by the rapid expansion of Cibolo and Schertz as San Antonio’s northeastern suburbs and by New Braunfels’s growth pushing south from Comal County. The county seat of Seguin sits at the Guadalupe River, surrounded by communities whose values have nearly doubled in the past decade as the San Antonio and Austin metros expand toward each other along the I-35 corridor.
At a 1.43% effective rate on properties whose values have climbed sharply, Guadalupe County’s $4,783 median annual bill is among the highest in Central Texas. Nearly two-thirds of property owners who protested in 2024 achieved reductions. Cibolo’s combined rate — one of the highest in the county — makes an accurate appraisal especially valuable. If your notice shows a significant increase, the informal settlement process at Guadalupe CAD is worth pursuing before your ARB hearing.

“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, 1836Guadalupe County residents moved here — or stayed here — because this stretch of Central Texas offered a quality of life that made the investment worthwhile. The founders of the Republic wrote that no property shall be taken without consent and just compensation. When rapid suburban growth drives appraisals to levels that bear no relationship to local income — when a longtime Seguin homeowner’s bill doubles because Cibolo is booming — the protest system is the constitutional correction. Look up your value. File your protest. Growth doesn’t entitle the taxing units to everything the market can bear.
