Highest rates in the Dallas metroplex
Collin County's 1.660% rate far exceeds nearby Comal County's 1.210% and state averages across the region. The $7,432 median tax is driven by Collin's booming real estate market, with median home values of $447,600—the highest among comparable counties.
Median home valued at $447,600
A typical Collin County home valued at $447,600 generates an annual property tax bill of $7,432 without a mortgage, or $7,903 with one included. This amounts to roughly $620 monthly—a substantial burden even for affluent homeowners in this fast-growing Dallas suburb.
High values make appeals especially worthwhile
In Collin County's hot real estate market, overassessment is common, and even a 5% appraisal reduction can save thousands annually on a half-million-dollar home. Homeowners should review their assessments closely and consider appealing if their appraisal exceeds recent comparable sales in their neighborhood.
