Collin County property values continued to rise in 2026, according to certified estimated taxable values released by the Collin Central Appraisal District.
CCAD mailed 2026 real property appraisal notices to property owners April 15. Owners who disagree with their valuations may file a protest by the deadline listed on their notice. Business personal property notices are also mailed separately.
The report said estimated Collin County property values increased 1.28% to $272.8 billion, with $7.87 billion in new property added to the tax rolls as of April 24, 2026.

“Collin County is still growing at a rapid pace as evidenced by the increase in new construction in most areas,” said Brian Swanson, assistant chief appraiser. “However, the year-over-year existing home values have decreased slightly. This will still result in a slightly upward trend for the taxing entities when we certify the values.”
