What Is a Property Tax Appeal?
A property tax appeal (also called a protest) is a formal process where you challenge the assessed value of your home with the Collin Central Appraisal District (CCAD). Under Texas Tax Code Section 41.44(a)(1), every property owner has the right to protest their appraised value if they believe it exceeds the property's actual market value.
In Collin County, over 150K+ property tax protests are filed each year. Homeowners who present well-documented evidence — particularly comparable sales data showing that similar homes sold for less than the appraised value — achieve success rates of 55-70%. The average successful appeal saves homeowners $1,100+ or more per year in reduced property taxes.
How Over-Assessment Happens
The CCAD assesses property values annually using mass appraisal methods — statistical models that estimate the value of thousands of properties at once. While efficient, these models often miss individual property characteristics like deferred maintenance, neighborhood micro-trends, or recent sales that suggest a lower value. When the assessed value exceeds what your home would actually sell for, you are over-assessed and paying more property tax than you should.
What Evidence Works Best
The strongest evidence in a property tax appeal is comparable sales — recently sold properties similar to yours in size, age, location, and features that sold for less than your assessed value. ClaimEngine automatically identifies the best comparables near your property, adjusts for differences in square footage, lot size, bedrooms, bathrooms, and year built, and calculates an indicated market value that you can present to the appraisal review board.
Other supporting evidence includes an independent automated valuation model (AVM) estimate, documentation of property condition issues (deferred maintenance, foundation problems, flood damage), and photos showing factors the mass appraisal may have missed.
Collin County Protest Deadlines and Process
The deadline to file a property tax protest in Collin County is May 15, 2026 (or 30 days after you receive your notice of appraised value, whichever is later). Filing early gives you a better chance of getting an earlier hearing date, which means a faster resolution.
File Your Protest
Submit your protest online through CCAD's Taxpayer Portal portal, by mail, or in person. You need your property account number and a brief statement that you believe the value is too high.
Informal Hearing
After filing, CCAD schedules an informal hearing — typically within 2 to 4 weeks. You meet one-on-one with an appraiser and present your comparable sales evidence. Many cases are resolved at this stage with an agreed reduction.
Formal Hearing (If Needed)
If you don't reach an agreement informally, you can proceed to a formal hearing before the Appraisal Review Board. You can attend in person, by phone, or submit evidence for a written decision.
