Collin County has seen some of the most dramatic property value increases in the Dallas-Fort Worth metroplex. Cities like Plano, Frisco, McKinney, Allen, Prosper, and Celina have drawn corporate relocations, new development, and rapid population growth — and appraisal values have followed. That growth is real. But the appraisal district’s numbers don’t always reflect market corrections, and too many property owners simply pay what they’re billed without questioning it.
You have the right to protest. In 2023, more than 115,000 Collin County properties were protested — and owners who did protest saved an average of nearly $1,975 per account. The tools below are your starting point.

Before your ARB hearing, a CAD appraiser may offer to settle informally. Review any offer carefully — you can accept or proceed to the formal hearing.
The Appraisal Review Board is independent of the CAD. Present your evidence clearly and concisely. Most hearings last 15–30 minutes.
Disagree with the ARB ruling? You may appeal to district court, binding arbitration, or SOAH (properties over $1 million).
