If you’re a homeowner in Dallas County, there’s a good chance you’ve looked at your annual property tax appraisal and wondered whether your home was valued too high. You’re not alone. Every year, thousands of Texas homeowners successfully protest their property’s appraised value, often reducing their tax burden and saving hundreds—or even thousands—of dollars.
The best part? Filing a property tax protest is something many homeowners can do themselves.
In this guide, we’ll walk you through the Dallas County property tax protest process, explain what evidence you should gather, and share practical tips to improve your chances of a successful outcome.
What Is a Property Tax Protest?
A property tax protest is your legal right to challenge the appraised value assigned to your property by the Dallas Central Appraisal District (DCAD). Because your annual property taxes are based largely on your property’s appraised value, lowering that value may reduce the amount of property taxes you owe.
Many homeowners assume the appraisal district’s valuation is final, but that’s not the case. If you believe your property has been overvalued or contains inaccurate information, you have the opportunity to request a review.
Who Can File a Property Tax Protest?
You may file a protest if you are:
- The property owner
- An authorized agent acting on behalf of the owner
- A property manager with authorization
- A business owner protesting commercial property
Most residential homeowners choose to file their own protests, especially if they have supporting evidence.
Important Filing Deadline
In most years, your protest must be filed by:
- May 15, or
- 30 days after your Notice of Appraised Value is mailed, whichever is later.
Missing the deadline may prevent you from protesting your property’s value until the following year unless a limited exception applies.
Step 1: Review Your Appraisal Notice Carefully
When you receive your Notice of Appraised Value, don’t focus only on the dollar amount. Verify that all of your property’s information is accurate, including:
- Square footage
- Lot size
- Number of bedrooms
- Number of bathrooms
- Garage spaces
- Pool
- Additional structures
- Construction quality
- Property condition
Even small errors can result in an inflated valuation.

Step 2: Gather Strong Supporting Evidence
Successful protests rely on objective evidence—not opinions.
Comparable Home Sales
One of the strongest pieces of evidence is recent comparable sales from your neighborhood.
Look for homes that are similar in:
- Size
- Age
- Condition
- Lot size
- Floor plan
- Location
Comparable sales should generally be as close as possible to January 1 of the tax year.

Repair Estimates
If your home needs repairs, obtain written estimates for items such as:
- Foundation repairs
- Roof replacement
- HVAC replacement
- Plumbing issues
- Electrical repairs
- Water damage
- Structural concerns
These documents help demonstrate why your home’s market value may be lower than similar properties.
Photographs
Take clear photos showing:
- Cracked foundations
- Roof damage
- Outdated kitchens
- Worn flooring
- Water intrusion
- Exterior deterioration
- Landscaping problems
Visual evidence often carries significant weight during the review process.
Recent Purchase Price
If you recently purchased your home, your closing documents may support your opinion of value.
While the appraisal district isn’t required to match your purchase price, it can be compelling evidence if the sale occurred near January 1 and was an arm’s-length transaction.
Step 3: File Your Protest
Dallas County makes filing straightforward.
You can submit your protest:
- Online
- By mail
- In person
The easiest option is through the Dallas Central Appraisal District Online Protest Portal:
Once submitted, you’ll receive confirmation that your protest has been accepted.
Step 4: Prepare for Your Informal Meeting
Before scheduling a formal hearing, DCAD often provides an opportunity to resolve your protest through an informal meeting.
During this meeting:
- Present your comparable sales.
- Show repair estimates.
- Provide photographs.
- Point out factual errors in your appraisal record.
- Stay professional and focused on evidence.
Many protests are successfully resolved during this stage, eliminating the need for a formal hearing.
Step 5: Attend Your Appraisal Review Board (ARB) Hearing
If you and the appraisal district cannot reach an agreement, your case will move to the Appraisal Review Board (ARB).
The hearing is relatively brief, usually lasting 15–20 minutes.
Bring organized copies of:
- Comparable sales
- Repair estimates
- Contractor bids
- Photos
- Closing documents
- Any additional supporting evidence
The appraisal district will present its valuation, you’ll present your evidence, and the ARB will issue a decision after reviewing both sides.
Common Mistakes to Avoid
Many homeowners weaken their case by making avoidable mistakes.
Avoid:
- Missing the protest deadline
- Using only Zillow or online estimates
- Bringing little or no documentation
- Becoming argumentative
- Ignoring incorrect property information
- Waiting until the hearing to organize evidence
Preparation is often the biggest factor in a successful protest.
Should You Hire a Property Tax Protest Company?
Some homeowners hire companies that specialize in property tax protests. These firms typically charge a percentage of any tax savings they achieve.
Hiring a professional may be worthwhile if:
- You own multiple properties.
- You have investment properties.
- Your property is high value or unique.
- You don’t have time to prepare your own case.
For many homeowners, however, filing independently is entirely manageable with the right preparation.

Frequently Asked Questions
Does filing a protest guarantee lower property taxes?
No. The Appraisal Review Board reviews the evidence presented by both sides before making a decision. Your value may remain the same or, in some circumstances, be adjusted based on the evidence.
Is filing a protest free?
Yes. Homeowners may file their own property tax protest at no cost.
Can I protest every year?
Yes. Texas property owners generally have the right to protest their property’s appraised value annually if they believe it is inaccurate.
Should I use Zillow as evidence?
Online estimates can provide general context, but they typically carry far less weight than comparable sales, repair estimates, photographs, and professional market data.
Final Thoughts
Property taxes are one of the largest recurring expenses of homeownership in Texas, but you don’t have to accept your appraisal without question. Taking the time to review your property record, gather strong evidence, and file a timely protest may result in meaningful tax savings.
Whether you’re planning to stay in your current home, purchase another property, or simply want a better understanding of your home’s market value, having accurate information is essential.
