Dallas County homeowners face some of the highest property tax rates in Texas âÃÂàand with over 700,000 parcels to value annually, the Dallas Central Appraisal District (DCAD) relies on mass-appraisal models that frequently overvalue individual properties. Recent market data shows that Dallas County had over 519,000 residential properties whose owners did not protest in 2025, despite many being assessed above fair market value. If you haven't protested, the odds are you are overpaying. Texas law gives you the right to challenge your assessment every year, and 82% of well-documented protests result in a reduction.
How DCAD Values Dallas County Properties
The Dallas Central Appraisal District uses a computer-assisted mass appraisal system to value every property in Dallas County as of January 1st each year. DCAD groups properties into market areas and applies statistical models to estimate value. The system is designed for efficiency at scale âÃÂànot accuracy at the individual property level. DCAD has a legal obligation under Texas Tax Code to value your property at 100% of its January 1st market value. If their model produces a number higher than your home's actual market value, you have grounds to protest.

Dallas Market Conditions and Why They Help Your Protest in 2026
Dallas home prices surged aggressively from 2020 through mid-2023, then the market shifted. Rising interest rates slowed demand, inventory increased, and days-on-market stretched significantly. In many Dallas neighborhoods, homes that were worth $450,000 in 2022 are now selling for $410,000âÃÂÃÂ$430,000. DCAD's models often lag this kind of correction, leaving homeowners assessed at peak values that no longer reflect reality.
Building Your DCAD Protest Case
Strong DCAD protests are built on comparable sales evidence. Find recent sales within your neighborhood of homes similar to yours that sold for less than your assessed value.
- ✓Recent comparable sales below your assessed value
