Who Determines Property Values in Collin County?

Property values in Collin County are determined by the Collin Central Appraisal District (CCAD).

Each year the appraisal district assigns a value to properties based on available market data. These values are used to calculate property taxes.

When Can You File an Appeal?

If your property value changes, you will typically receive a Notice of Appraised Value.

Appeals must be filed before the deadline listed on that notice. Deadlines generally occur in the spring each year. Contact the Collin Central Appraisal District or review your notice for the specific deadline that applies to your property.

Who Reviews Property Tax Appeals

Appeals are reviewed by the Appraisal Review Board (ARB).

The ARB examines the evidence submitted by both the property owner and the appraisal district before issuing a decision. The ARB operates independently from CCAD.

Reasons Property Owners File Appeals

Common reasons for filing an appeal include:

• The assessed value is higher than recent comparable sales
• Property characteristics listed in county records are incorrect
• Market values declined but the assessment did not adjust
• Unequal valuation compared with nearby properties

Evidence That May Help an Appeal

Supporting information may include:

• Recent comparable property sales
• Corrections to county property records
• Photographs of property condition
• Repair estimates
• Neighborhood sales data

The type and strength of evidence required will depend on the grounds for your appeal and the decisions of the Appraisal Review Board.

Understanding the Appeal Process

The typical Collin County appeal process involves:

• Reviewing the appraisal district's value for your property
• Gathering supporting evidence such as comparable sales or record corrections
• Submitting a protest before the deadline on your Notice of Appraised Value
• Attending an Appraisal Review Board hearing if necessary

Some cases may be resolved during an informal review before a formal hearing takes place.
