About Property Taxes in Collin County, Texas
Collin County taxes run significantly higher
At 1.660%, Collin County's effective tax rate ranks among the highest in the nation, well above the national median of 1.41%. The median property tax of $7,432 is nearly three times the national median of $2,690, reflecting both high property values and elevated tax rates.
Top-tier tax burden among Texas counties
Collin County's 1.660% effective rate significantly exceeds Texas's 1.276% state average—a gap of 0.384 percentage points that places it among the state's highest-taxed counties.

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.
