Collin County is no longer the rural outpost it once was. As one of North Texas’ premier suburbs, booming growth continues to push property values — and taxes — sky-high.
In 2025, residential property values jumped 4.9%, while commercial values surged 14.8%. Unsurprisingly, property tax protests have become a vital tool for homeowners and businesses alike, with over 26% of properties appealed annually.
Residential Property Wins Modest Reductions
According to O'Connor Tax Reduction Experts, informal appeals shaved $1.16 billion off the county’s residential value, cutting the total to $195.01 billion, a 0.6% reduction. Larger homes, especially those over 6,000 square feet, saw the biggest gains, clawing back 5.3%. Homes between 2,000 and 3,999 square feet, the county’s most common, saw a 0.4% reduction.
Newer homes weren’t spared from rising assessments. Construction since 2001 makes up 61% of the county’s residential value, with 14% from new builds alone. While new homes increased in value by 30.5%, informal appeals trimmed that by 1.1%.
Commercial Properties See Bigger Cuts
Commercial property owners fared better in early protests. Initial appeals reduced taxable value by 6.1%, reclaiming $4.32 billion. Apartments, the county’s top commercial property type, led the way with an 8.3% reduction after a 16.5% value increase.
Other commercial sectors also saw relief:
- Offices: down 4.4%
- Hotels: down 13.4%
- Retail: down 4.9%
- Warehouses: down 3.6%
Apartments, offices and retail built between 2001 and 2020 made up the largest shares and benefited most from protests. For example, new hotels faced a whopping 40.5% value increase but clawed back 13.4% in appeals.
ARB Hearings Still To Come
These reductions are just the beginning. Most property owners in Collin County escalate to the Appraisal Review Board (ARB), where deeper cuts are often won. ARB hearings will stretch through the year, with some cases escalating further through lawsuits or arbitration, common for high-dollar properties.
Collin County's Growth Comes At A Price
While informal appeals offered some relief, the county’s rapid growth continues to push property taxes higher. New construction, particularly commercial, drives much of the increase. Until the ARB process wraps up, it’s unclear just how much property owners will save — but in Collin County, the fight over valuations is just heating up.
