I have filed thousands of property tax protests across the Rio Grande Valley. The process is straightforward once you understand it, but there are pitfalls that trip people up every year. Here is exactly how I approach every protest, whether it is a $150,000 starter home in Weslaco or a $2 million commercial property in McAllen.
Step 1: Review Your Notice Immediately
When your Notice of Appraised Value arrives in April or May, do not set it aside. Open it right away and check three things:
- The value change: How much did it go up from last year? Anything over 5-10% deserves a closer look.
- The property details: Is the square footage correct? Bedroom and bathroom counts accurate? Lot size right?
- Your deadline: Mark it on your calendar. For the 2026 tax year, the protest deadline is May 15, 2026 or 30 days from the date your notice was mailed, whichever is later.
Pro Tip
Even if your value only went up a little, check what similar homes in your neighborhood are assessed at. You might be valued $30,000 higher than the house across the street with the same floor plan.
Step 2: Research Your Comps
This is where protests are won or lost. You need comparable sales, meaning recent sales of similar properties near you. I look for homes that are:
- Within half a mile of the subject property
- Similar in size (within 10-15% square footage)
- Same bedroom and bathroom configuration
- Built around the same time
- Sold within the past 12 months
In the RGV, neighborhoods can vary dramatically block by block. A comp from Tres Lagos is not appropriate for a home in Palmview, even if they are a similar size. Location specificity matters here more than in most Texas markets.
Step 3: File the Protest
You can file online, by mail, or in person. Here are your options for each county:
Hidalgo County (HCAD)
Online: File through the HCAD website for immediate confirmation. By mail or in person: 4405 S. Professional Dr., Edinburg, TX 78539.
Cameron County (Cameron CAD)
Online: File through the Cameron CAD website. By email: protest@cameroncad.org. By fax: 956-399-6969. By mail: PO Box 1010, San Benito, TX 78586. Cameron also offers walk-in informal conferences from approximately April 14 through May 16.
When filing, you will choose your protest grounds. The two strongest options are:
- Market value is too high: Your home is worth less than the assessed value based on comparable sales.
- Unequal appraisal: Your home is assessed higher than similar properties in the area.
You do not need all your evidence ready when you file. Just get it filed before the deadline. You will have weeks to prepare your full case before your hearing.
Step 4: Build Your Case
Between filing and your hearing date, I compile a detailed evidence packet. Here is what goes into a strong presentation:
- A comparable sales analysis with 3-6 recent sales
- Property photos showing condition issues (old roof, foundation cracks, outdated systems)
- Repair estimates if applicable
- A comparison chart showing your value versus similar nearby properties
- Any errors in the district's records
I present everything in a clean, organized format. ARB panels see hundreds of cases. Making it easy for them to understand your argument goes a long way.
Step 5: The Hearing
Most protests start with an informal conference, where you meet one-on-one with an appraiser to negotiate a value. Many cases settle here without going to a formal ARB hearing. If you cannot reach agreement, the case moves to the ARB panel.
ARB hearings in Hidalgo and Cameron counties are straightforward. Here is what to expect:
- Arrive 15 minutes early with multiple copies of your evidence
- You present first, typically for 5-10 minutes
- The district representative responds with their data
- The panel asks questions and makes a decision
Hearing Advice
Stay calm, stick to the facts, and never argue about tax rates. The hearing is only about value. If you get emotional or confrontational, you lose credibility with the panel.
Step 6: After the Decision
You will receive a written decision. Three outcomes are possible:
- Full reduction: You got the value you asked for. Your tax bill drops accordingly.
- Partial reduction: They lowered it, but not as much as you wanted. Still a win in most cases.
- No change: The panel sided with the district. You can still pursue binding arbitration or district court.

Key 2026 Deadlines
2026 Property Tax Deadlines
April 15 — BPP rendition deadline. April 30 — Homestead exemption application deadline. May 15 — Protest filing deadline (or 30 days from notice, whichever is later). January 31, 2027 — 2026 tax payment deadline.
If you decide to protest on your own, the most important thing is to file before the deadline and bring organized evidence. The worst outcome is your value stays the same — there is zero risk to protesting, and the potential savings can be significant.
