The average successful property tax protest in Collin County saves homeowners $1,350 per year in property taxes. With 400K+ properties in the county and an average assessment of $480,000, even small percentage reductions can mean significant dollar savings.
Your actual savings depend on several factors: how much your current assessment exceeds fair market value, your local tax rates (school district, city, and special districts), and whether you qualify for any exemptions. Collin County has seen assessment increases averaging 12.1% year-over-year, which means many properties may be over-assessed compared to actual market conditions.

Filing a property tax protest with the Collin County Central Appraisal District (CCAD) is straightforward. You have three options: file online through the CCAD website, mail a written protest, or file in person at the CCAD office.
Step 1: Complete the Notice of Protest
Download Form 50-132 from the Texas Comptroller's website or use theCCAD's online portal. Check the box for "Value is over market value" and/or "Value is unequal compared with other properties."
Step 2: Submit by the deadline
File online for fastest processing, or mail to ensure delivery before May 15, 2026. Keep a copy of your submission.
Step 3: Receive hearing notification
The CCAD will mail you a hearing date, typically within 2-4 weeks. Most Collin County protests are first scheduled for an informal hearing with an appraiser.
Step 4: Prepare your evidence
Gather comparable sales, photos of property condition issues, repair estimates, or any documentation supporting a lower value.
Step 5: Attend your hearing
Present your case at the informal hearing. If you reach an agreement, you're done. If not, you can proceed to the ARB (Appraisal Review Board) for a formal hearing.
The most effective evidence for Collin County property tax protests falls into three categories: comparable sales, property condition, and unequal appraisal. The CCAD appraisers respond best to objective, documented evidence.
Comparable Sales (Most Effective)
Find 3-5 similar properties that sold for less than your assessed value within the past year. "Similar" means: same neighborhood, similar square footage (+/- 20%), similar age (+/- 10 years), and similar features. Pull data from realtor sites, county records, or MLS if you have access.
Property Condition Issues
Document any problems that affect value: foundation issues, roof damage, outdated systems, needed repairs. Bring photos, inspection reports, or contractor estimates. The CCAD can't know about these issues from their records.
Unequal Appraisal
Show that similar properties in your area are assessed at lower $/sqft. This is where TexasTaxSignal helps—our neighborhood comparison shows you exactly where you stand relative to similar properties.
