The Collin County property tax protest process for 2026 begins when your notice of appraised value arrives. From there, you should check your deadline, review your property details, compare your value to similar homes, and file your protest if needed.
Step 1: Check Your Protest Deadline
Start by reviewing your notice for the deadline.
In most cases:
- The deadline is May 15, or
- 30 days after your notice was mailed
Because notices are sent at different times, always confirm the exact date listed.
Step 2: Review Your Property Details
Next, go through your property information carefully.
Check for:
- Incorrect square footage
- Missing or extra features
- Wrong condition or quality rating
Even small errors can increase your appraised value.
Step 3: Compare Your Value to Collin County Comps
After reviewing your details, compare your value to similar homes in Collin County.
Focus on:
- Recent sales (last 6–12 months)
- Homes in your area (Plano, Frisco, McKinney, etc.)
- Similar size, condition, and features
If similar homes are valued lower, you may have a strong case.
Step 4: File Your Protest Online (CCAD)
If something looks off, file your protest with Collin Central Appraisal District (CCAD).
You can:
- File online through the CCAD website
- Submit your protest before the deadline
Filing early gives you more time to prepare.
Step 5: Gather Your Evidence
Strong evidence improves your chances.
Include:
- Comparable sales
- Photos of your property’s condition
- Repair estimates
- Property record details
Clear and organized evidence makes your case stronger.
Following this step-by-step plan for your Collin County property tax protest helps you stay on track and build a stronger case for a lower value.
