Evidence Tips for Collin County
- Collin County is one of the fastest-growing in Texas. Use recent comps (past 6 months).
- New construction comparables must be carefully adjusted for upgrades and lot premiums.
- Check CCAD records for correct square footage and room counts.
- Unequal appraisal can be compelling in newer subdivisions with uniform construction.
About Collin County Property Taxes
Collin County has been one of the fastest-growing counties in the United States for over a decade. Cities like Plano, Frisco, McKinney, and Allen have grown from suburban outposts into major employment centers with large, established residential markets. That sustained growth has driven property values sharply upward, and CCAD appraises a rapidly expanding base of both new and resale homes across dozens of master-planned communities.
For homeowners, this pace of growth cuts both ways. Rising demand supports higher values, but it also creates conditions where appraisals can overshoot actual market conditions, especially when builders are offering incentives that inflate reported sale prices. Understanding how your specific neighborhood fits into the broader county picture is the foundation of an effective protest.
Protest Preparation Tips
New construction is one of the most common protest situations in Collin County. Builders frequently sell homes with incentives, appliance packages, and lot premiums that inflate the recorded sale price beyond what a comparable resale home would fetch. When building your protest case, use recent closed resale sales from established inventory rather than new construction list prices as your comparables.
In master-planned communities where many homes share the same builder, floor plan, and construction year, unequal appraisal can be a particularly strong argument. If CCAD has appraised otherwise identical homes at meaningfully different rates, that disparity is direct evidence for a reduction under Texas Tax Code Section 41.43.
Building Your Evidence
Collin County's aggressive development pace means CCAD records sometimes contain errors on newer homes. Square footage, room counts, and construction quality ratings may not match what was actually built. Compare CCAD's online record for your property against your builder's final plans, your deed survey, or a licensed appraiser's measurement. Also check whether lot features like greenbelt backing, pond views, or cul-de-sac location have been accurately recorded, since these factors feed directly into CCAD's estimate.
Local Verification Reminder
CCAD processes a large volume of protests each season due to the county's size and continued growth. Filing early can mean faster scheduling and more appraiser availability. Always confirm current protest procedures, available online filing options, and evidence submission requirements directly at collincad.org or by calling 469-742-9200 before your deadline. Portal features and requirements can change from year to year.
Helpful Next Steps
- Review your property record at collincad.org for square footage and room count accuracy
- Compare your appraised value per square foot to similar homes in your subdivision
- Use recent resale closed sales, not new construction list prices, as comparables
- File your protest before the deadline and save your confirmation
- If the informal hearing does not resolve the issue, request an ARB hearing
