Hays CAD accepts protests online and by mail, with evidence submitted ahead of the informal review. Recent closed sales from your own subdivision are the strongest card in a Hays protest. The legal framework is the same statewide: you can argue market value (Tax Code §41.41) and equal-and-uniform appraisal (§41.43) in the same protest, and the deadline is May 15 or 30 days after your notice — whichever is later.

Why flat fee instead of a percentage
Contingency protest firms typically charge 25–50% of your first-year savings, every year you use them. A $49 flat-fee packet means a homeowner who saves $1,000 keeps $1,000 minus $49 — not $500 to $750. The trade: you file it yourself, with the checklist walking you through each step.
Questions
When is the Hays County protest deadline?+
Texas Tax Code §41.44 sets the deadline at May 15, or 30 days after Hays CAD delivers your notice of appraised value, whichever is later. If you miss it, you generally wait until next year — which is why we open the waitlist early.
Do you file the protest with Hays CAD for me?+
No. This is a self-file document product. You file the protest with Hays Central Appraisal District yourself — the packet includes the evidence documents and a step-by-step filing checklist.
Do you guarantee Hays CAD lowers my value?+
No. Hays Central Appraisal District and the Hays County appraisal review board decide final values. The product is the evidence packet, not a guaranteed tax result.
