To protest an appraisal on Guadalupe Appraisal District’s rolls, file a written notice of protest by the applicable deadline and present your case to the appraisal review board if it is not resolved informally.
The district’s protest procedures say owners may challenge market value, unequal appraisal, exemptions, ownership and several other appraisal actions. Start with the notice you received: its mailing or delivery date and the kind of decision determine which deadline to check.

Property owners have the right to protest actions concerning their property tax appraisals.Guadalupe Appraisal District ↗
The same district protest process applies to property on Guadalupe Appraisal District’s rolls whether the owner uses its Seguin or Schertz office. The appraisal review board, or ARB, is separate from the appraisal office and hears disputes submitted to it. It does not appraise property in the district’s day-to-day work. An owner should identify the property, the disputed action and the deadline before choosing how to file.
Check the deadline
The usual deadline is May 15 or 30 days after the district mails the notice of appraised value, whichever is later. The May 15 date for 2026 has passed; that alone does not establish the deadline for an owner whose notice was mailed later. A deadline that falls on a weekend or legal state or national holiday moves to the next business day. The district’s procedures also describe special deadlines and a limited good-cause route for late protests.
