Collin Central Appraisal District (CCAD) Protest Procedures and What to Expect
While Texas law governs the overall protest framework, CCAD procedures and timelines are county-specific. Understanding how the Collin Central Appraisal District handles protests gives you a strategic advantage.
Filing and Confirmation
Once your protest is submitted, CCAD will confirm receipt and place your property into the protest system. Due to volume, processing timelines vary significantly throughout the season.
Evidence Exchange and Informal Review
After filing, CCAD may make appraisal evidence available, including:
- Comparable sales used by CCAD
- Market data supporting the appraised value
- Property record information on file
Many Collin County protests are resolved during an informal review, which is a negotiation with CCAD appraisal staff prior to any formal hearing.
Submitting strong evidence early often improves settlement outcomes. Use our Collin County property tax protest evidence checklist to make sure you have what you need.
ARB Hearing Process in Collin County
If no agreement is reached informally, CCAD schedules a hearing before the Collin County Appraisal Review Board (ARB).
ARB hearings:
- Are conducted by independent board members
- Require evidence submission by strict deadlines
- Allow both CCAD and the property owner or representative to present arguments
Property owners are not required to attend and may appoint a representative.
