Every year, thousands of Texas homeowners pay more in property taxes than they legally owe — simply because they never challenge their appraisal. The good news? Protesting is easier than you think, it’s free, and it works.

What Is a Property Tax Protest?

In Texas, your local county appraisal district (CAD) sets the assessed value of your home each year. That value is used to calculate your tax bill. If you believe the assessed value is too high — or if errors exist in your property record — you have the legal right to protest it before the Appraisal Review Board (ARB).

Protesting does not mean your taxes will automatically go down. It means you’re asking for a fair, evidence-based review.

Step 1: Check Your Notice of Appraised Value

Each spring (usually April), your CAD mails or posts online a Notice of Appraised Value. This tells you what your property is assessed at for the upcoming tax year. Review it carefully:

• Is the square footage, bedroom count, or lot size correct?
• Does the value seem significantly higher than what your home would sell for?
• Did the value jump more than neighboring properties?

Step 2: File Your Protest by the Deadline

You must file a protest by May 15th (or 30 days after your notice is delivered, whichever is later). You can file:

• Online through your county appraisal district’s website (most counties now offer this)
• By mailing or hand-delivering Form 50-132 to your CAD office

Missing the deadline almost always means losing your right to protest for that year — so don’t wait.

Step 3: Gather Your Evidence

The strongest protests come with solid comparable sales data (“comps”) — recent sales of similar homes in your area that suggest a lower market value. Good sources include:

• Your county CAD’s online portal (many list comparable sales themselves)
• Zillow, Realtor.com, or HAR.com (for Houston-area homes)
• A recent appraisal from a licensed appraiser (strongest evidence, but optional)
• Photos or repair estimates documenting damage, deferred maintenance, or defects

Step 4: Attend Your Hearing (or Settle Informally)

After you file, many CADs will offer an informal settlement before your formal ARB hearing. This is a quick conversation — often just 15–20 minutes — with an appraiser who can reduce your value on the spot if your evidence is compelling.

If you don’t settle informally, you’ll attend a formal ARB hearing. Bring printed copies of your evidence, stay calm and factual, and present your comps clearly. Most hearings are brief and low-pressure.

Tips to Strengthen Your Protest

• Use comps within 1 mile and sold within the last 12 months when possible
• Compare your home’s assessed value per square foot to neighbors’
• Check for exemptions you may qualify for — homestead, over-65, disabled veteran, and others can significantly reduce your bill
• Consider using a property tax consultant if your home is high-value — many work on contingency

The Bottom Line

Protesting your property taxes in Texas is one of the most direct ways to lower your annual housing costs. The process is accessible to any homeowner willing to spend a few hours gathering evidence. With no fee to file and a genuine chance of success, there’s little reason not to try.

The worst outcome is that your value stays the same. The best outcome is hundreds — sometimes thousands — of dollars back in your pocket.
