How to protest your property taxes in Cameron County
Your Cameron County property value is set by the Cameron Appraisal District (CAD). If your appraisal notice says your home is worth more than it would sell for — or more than similar homes on your street — you can protest it. Here's exactly how it works in Cameron County.
Filing deadline
May 15, or 30 days after your notice is delivered — whichever is later
Where to file
Look up your property
Step 1: Check your appraisal notice
Appraisal districts across Texas mail notices of appraised value in the spring, usually April. Compare the market value on your notice with recent sales of similar homes nearby. If the district's number is higher, you have grounds to protest. You can also protest if your home is appraised higher than comparable homes on your street (an unequal appraisal protest).
Step 2: File your protest with CAD
File through the Cameron public portal with the Owner ID and PIN printed on your notice. There you can upload evidence, view the district's evidence packet, and accept or decline a settlement.
The statewide deadline is May 15, or 30 days after your notice was delivered if that's later (Texas Comptroller). Miss it and you generally wait until next year.
Step 3: Gather your evidence
The strongest evidence is recent sales of homes like yours: similar size, age, and condition, close by, and sold near January 1 of the tax year. Add photos of anything that lowers your value (foundation issues, an old roof, needed repairs) and contractor estimates if you have them.
Cameron County tips
- Before accepting a settlement offer in the portal, compare it with your own comparable-sales value.
- The portal shows the district's evidence packet. Read it before your informal meeting.
- Search your property on cameroncad.org to confirm its listed details.
Step 4: The informal conference
After you file, CAD typically offers an informal meeting with an appraiser. Present your comparable sales and any condition evidence. Most protests are settled here. If the offer is fair, you can accept it and you're done.
Step 5: The ARB hearing (if you don't settle)
If you don't settle, the Appraisal Review Board (ARB) holds a formal hearing and must give you at least 15 days' notice. You can attend in person, by phone, or by video, or submit a written affidavit instead. The board weighs your evidence against the district's and issues a decision.
