Dallas County property owners have watched their appraised values climb year after year. The county's real estate market has been among the hottest in Texas, driven by corporate relocations, population growth, and a construction boom that has reshaped entire neighborhoods. But just because the market went up doesn't mean the appraisal district got your individual property's value right.
If you own residential or commercial property in Dallas County, this guide covers everything you need to know to protest your 2026 appraised value.
The Dallas Central Appraisal District (DCAD)
The Dallas Central Appraisal District handles property valuations for all taxing units within Dallas County. That includes the city of Dallas, Irving, Garland, Mesquite, Richardson, Grand Prairie (the Dallas County portion), and every school district, college district, and special district in the county.
DCAD's online portal at dallascad.org lets you search for your property, review your appraised value and property details, and file a protest electronically. Use it — the online system is more efficient than mail or in-person filing.
2026 Timeline and Deadlines
Appraisal notices are typically mailed in mid to late April. Your deadline to file a protest is May 15, 2026 or 30 days after the date your notice was mailed — whichever gives you more time. Mark the date. Once it passes, you've lost your right to protest for the entire tax year.
DCAD also offers early informal settlements through their online portal. In some cases, you can review a proposed value and accept or counter it before formal hearings are even scheduled. If DCAD offers you a value you're comfortable with, accepting it early saves everyone time.
How to File in Dallas County
Filing is straightforward:
- Online: Through dallascad.org — the fastest and most convenient method
- By mail: Send Form 50-132 to Dallas Central Appraisal District, 2949 N. Stemmons Freeway, Suite 100, Dallas, TX 75247
- In person: Visit the DCAD office at the Stemmons Freeway location
When filing, check the box for "value is over market value" and, if applicable, "value is unequal compared with other properties." Filing on both grounds gives you maximum flexibility during your hearing.
What's Happening with Dallas County Values in 2026
After several years of aggressive increases, the Dallas County market has started to show more nuance. Some neighborhoods are still appreciating. Others have plateaued. A few — particularly in areas with high inventory or where new construction has stalled — have seen values soften.
This mixed picture is actually favorable for protesters. When the market is uniformly hot, it's harder to argue that your value is too high because the comps support high prices. In a more complex market, there's more room to find comps that support a lower number — especially if the appraisal district applied a blanket increase across your neighborhood without distinguishing between properties that are genuinely appreciating and those that aren't.
Dallas County Neighborhoods and Considerations
North Dallas and Far North Dallas: These areas around Richardson, Plano (the Dallas County portions), and along the 75 corridor have seen persistent growth driven by the Telecom Corridor and corporate relocations. Values are high, but so are expectations. If your specific property has condition issues or negative location factors (backing up to a highway, for instance), the district's model may not account for it.
East Dallas and Lakewood: Gentrifying neighborhoods where older, unrenovated homes sit next to complete tear-down rebuilds. The appraisal district sometimes applies the appreciation from renovated homes to unrenovated ones. If your 1940s bungalow is being valued like the new construction two doors down, that's a strong protest argument.
Oak Cliff and Southern Dallas: These areas have seen targeted investment but remain uneven. Block-by-block conditions vary significantly, and mass appraisal models sometimes struggle to capture these micro-differences. Check your comps at the street level, not just the zip code level.
Irving and the Las Colinas area: The continued development around the TxDOT campus and Hidden Ridge has pushed values up in surrounding residential areas. But properties further from these centers of development may not be benefiting from the same market forces. Challenge comps that assume uniform appreciation across the entire city.
Garland and Mesquite: Working-class neighborhoods where property taxes are a particularly significant portion of household expenses. Even modest reductions matter. Check for unequal appraisal — if your neighbor's similar home is appraised $15,000 lower, that's a straightforward argument.
Building Your Case for 2026
The best evidence for a Dallas County protest includes:
- Three to five comparable sales within one mile, closed within the past 12 months, that sold for less than your appraised value
- Appraisal records of similar properties in your neighborhood that are valued lower (for the unequal appraisal argument)
- Photos and documentation of any condition issues — deferred maintenance, needed repairs, negative external factors
- Your recent purchase price, if you bought within the last two years for less than the appraised value
Pull your comparable sales from DCAD's website, which provides recent sales data organized by location. You can also use the Texas Comptroller's property search or ask a real estate agent to pull MLS data for your area.
After the Protest
If your informal hearing doesn't produce a satisfactory result, your case moves to the ARB. Dallas County's ARB hearings run from late May through the fall. Come prepared with your evidence organized, enough copies for the panel, and a clear, concise presentation.
For properties appraised at $5 million or less, binding arbitration is available as an alternative to district court if you disagree with the ARB's decision. The arbitration fee depends on your property value but is often more cost-effective than litigation.
Dallas County is one of the most active protest markets in Texas. Thousands of property owners file every year, and many of them succeed in getting their values reduced. If you own property in Dallas County, there's no reason not to at least review your appraisal and consider whether a protest makes sense for your situation.
