Dallas County Property Tax Protest: How to Do It Yourself
If your Dallas County appraisal notice shows a value that seems too high, you can protest it — free, on your own, without hiring a company. The Dallas Central Appraisal District/DCAD runs the process, and most homeowners can navigate it start to finish in a few hours. This guide covers who handles your protest, what grounds you can use, how to file, and what evidence actually works.
Who Handles Your Protest: DCAD and the ARB
DCAD sets your property's appraised value — the number your tax bill is based on. It is separate from the cities, school districts, and other taxing units that collect taxes; it only determines value. A successful protest lowers that appraised value, and every taxing unit adjusts your bill accordingly.
Hearings are decided by the Appraisal Review Board/ARB — an independent panel, not DCAD staff. The ARB's job is to weigh your evidence against DCAD's, not to defend the district's figure.
The Protest Deadline — Confirm It Before Anything Else
Under Texas law, the protest deadline is generally May 15 or 30 days after DCAD mailed your Notice of Appraised Value, whichever is later. Miss it and you lose your opportunity for that tax year — there is no grace period. Verify the current deadline at dcad.org before filing. (Other counties follow the same framework — see our Denton County guide for county-specific details.)
Grounds for Protest: Two Arguments Worth Making
You need a legal ground — a reason — to file. For most Dallas County homeowners, two grounds apply:
- Market value: DCAD's appraised value exceeds what your home would realistically sell for today. Support this with recent comparable sales — similar homes nearby that sold for less.
- Unequal appraisal (equity): Your home is assessed at a higher ratio to market value than comparable nearby properties. Texas is one of the few states where this uniformity argument alone can produce a reduction — see also guides for Denton County and Tarrant County where the same ground applies.
You can check both grounds on the same protest form — most homeowners do, and it costs nothing extra to argue both simultaneously.
How to File Your Protest With DCAD
DCAD accepts protests online via its e-file portal at dcad.org, by mail (Form 50-132), or in person. Online filing is fastest and generates a confirmation. State your grounds — market value, unequal appraisal, or both — when you file. You do not need to submit evidence at filing; bring it to the hearing. For Denton County filers, see the Denton County property tax protest guide for that district's portal.
After filing, DCAD may send an informal settlement offer before your ARB hearing — many protests resolve here. If you reject it or don't receive one, your case moves to a formal ARB hearing (usually 15–30 minutes) where both sides present evidence and the panel decides. See the Denton County property tax protest guide if you own property there.
Evidence That Moves the ARB
Bring printed copies of everything — the ARB panel will not scroll through your phone. The most persuasive evidence:
- Recent comparable sales (comps): 3–5 homes in your neighborhood with similar square footage, lot size, age, and condition that sold within the past 12 months for less than DCAD's appraised value.
- Appraised value per square foot for neighboring properties from DCAD's public records — useful for an unequal-appraisal argument if your per-square-foot figure is higher than nearby homes. (The same approach applies in Denton County — see the Denton County property tax protest guide.)
- Photos or repair estimates documenting condition issues DCAD may not have accounted for — foundation problems, roof damage, deferred maintenance.
- A recent independent appraisal, if you have one (from a refinance, for example) — it carries real weight with the ARB.
A reduction is not guaranteed — it depends on how well your evidence aligns with the ARB's standards. Strong, current comps are the most reliable path. For a comparison of outcomes across North Texas counties, see our Tarrant County property tax protest guide.
