What the Collin County numbers mean
The median is the midpoint of the county's actual bills: half of Collin County homeowners pay more than $7,432 a year and half pay less. The exact bill for any one home depends on its assessed value, exemptions, and which school, municipal and special districts cover it.

Collin County's medians imply a derived rate of 1.66%; applied illustratively, a $400,000 home would owe about $6,640 a year, or around $553 a month spread evenly. Individual properties depart from the illustration in both directions.
Checking your assessment in Collin County
If your bill looks wrong, work through these steps:
1. Get your property record card from the assessor and check the basics — living area, lot size, bedrooms, condition, and any exemptions you should have.
2. Compare your assessed value with recent sale prices of similar homes in Collin County.
3. Talk to the assessor's office informally first; clear errors are often fixed without a hearing.
4. If needed, file a formal appeal with the local review board before the deadline on your assessment notice, with your evidence attached.
5. Keep paying the bill as issued while the appeal runs, unless your notice says otherwise — unpaid taxes accrue penalties regardless of an appeal.
