Step-by-Step: Filing Your Protest

Receive and review your appraisal notice

DCAD mails appraisal notices in April. The notice shows your 2026 certified appraised value and the protest deadline. You can also look up your current value at dallascad.org by searching your address or account number. You may protest even if you did not receive a mailed notice.

Prepare your evidence

Dallas County is large and diverse — neighborhood comparisons are critical. The strongest argument is §41.43 Unequal Appraisal: demonstrating your home is appraised at a higher $/sqft than similar properties in your DCAD appraisal neighborhood. You need:

3–5 comparable properties in the same DCAD appraisal neighborhood (same geo_cd or nbhd code)
Each comp's appraised value, sqft, and $/sqft from DCAD public records
Your own property's DCAD data for direct comparison

File online at dallascad.org iFile

Go to dallascad.org/protestifile.aspx and click "iFile Protest". You'll need your 11-digit DCAD account number. Select protest reasons — choose "Unequal Appraisal" at minimum, and also "Value over Market Value" if applicable. Upload your evidence as a PDF attachment. You will receive a confirmation with a protest number.

Wait for the county's response — often no call needed

After filing and uploading your evidence, the appraiser reviews your packet — usually within a few days to two weeks. Many protests are resolved entirely online through a written settlement offer in the DCAD portal — no phone call, no in-person visit required. Log back in to check for an offer and accept or counter.

If DCAD doesn't settle online, they will schedule an informal hearing by phone or in person at 2949 N Stemmons Fwy. Due to Dallas County's high protest volume (~200,000+ annually), hearings may be scheduled several weeks after filing. Your evidence packet is already on file — no extra preparation needed.

Respond to the offer or present your case

If you receive an online settlement offer: Compare it to your target value (page 1 of your evidence packet). Accept if it's within 5–10% of your target. Counter or decline to proceed to a hearing if it's significantly above your target.

At a phone or in-person hearing, be direct and cite specific data:

Open with: "I'm protesting under §41.43. My property at [address] is appraised at $X/sqft. These properties in the same neighborhood are appraised at $Y/sqft after size and age adjustments."
State your requested target value clearly
If the appraiser pushes back, ask: "What $/sqft are you using for this neighborhood?"

DCAD appraisers have discretion to offer a reduction at the informal stage. Most Dallas County settlements happen here.

Accept settlement or proceed to ARB

If you and the DCAD appraiser reach an agreement, sign the settlement. The reduced value is final for 2026 and you waive your right to further protest for this tax year.

If no agreement is reached, your case goes to the Dallas ARB — a panel of 3 independent board members. ARB hearings are typically held at DCAD's main office. You present the same evidence; the panel issues a binding order within days.

Tips for Winning Your Hearing

Use DCAD's own neighborhood codes

DCAD assigns a 'geo_cd' neighborhood code to every property. Comps from the same geo_cd carry the most weight — DCAD uses these zones to set mass appraisal ratios.

File before April 30

Dallas County receives the highest volume of protests in DFW. Filing early gives you better hearing slot availability and avoids the May rush.

Bring printed comps

For in-person hearings, bring 2 printed copies of your evidence packet — one for the appraiser, one for you. DCAD may not print materials for you.

Target 25th percentile, not lowest comp

Asking for the median $/sqft of your selected comps is highly defensible. Asking for the single lowest property in Dallas County will be dismissed.

Don't over-explain

DCAD appraisers are experienced. State your $/sqft disparity, your comps, your number, and stop. Over-arguing weakens your position.

Check for homestead exemption

Before protesting, confirm your homestead exemption is applied at dallascad.org. The 10% appraisal cap only applies if you have an active homestead exemption.

Frequently Asked Questions

How do I find my DCAD account number?

Search your address at dallascad.org. Your 11-digit account number appears on the property detail page and on your mailed notice.

Can I protest online if I live outside Dallas County?

Yes, as long as the property is in Dallas County. DCAD iFile is available to all property owners regardless of where they live.

How does the 10% homestead cap work?

If you have a homestead exemption, your taxable value cannot increase by more than 10% per year — but your appraised value can still increase more. Protesting the appraised value reduces the future ceiling for the cap.

What if I disagree with the ARB's decision?

You can appeal an ARB order to district court (expensive) or to the State Office of Administrative Hearings (SOAH) for properties under $5M. Most homeowners accept the ARB result.

Is there a fee to file a protest?

No. Filing a property tax protest with DCAD is free.

What if I recently purchased my home at a lower price?

Texas is a non-disclosure state, so sale price is not automatically reported to DCAD. However, you can voluntarily provide a recent arm's-length HUD-1/closing disclosure as evidence of market value.
