Travis BunnTravis Bunn·Updated July 24, 2026

Cameron County is the southernmost county in Texas with a population of approximately 434,940 as of 2026. The county seat is Brownsville, which is also the largest city with a population of 194,626, followed by Harlingen, San Benito, Port Isabel, and South Padre Island. Cameron County homeowners face a median annual property tax bill of $1,458, which is below the national median of $2,400, but the county's effective tax rate of 1.33% remains higher than the national median of 1.02%. Property tax protests are particularly important in Cameron County because properties are assessed at 100% of market value, and even a small overassessment can result in hundreds of dollars in annual overpayments that compound year after year.

How Cameron County Assesses Property

100%of market value

Assessed by: Cameron Appraisal District (CCAD)

Assessment cycle: annual

Notices typically mailed: April (beginning April 6th for 2026)

In Texas, properties in Cameron County are assessed at 100% of their market value as of January 1st each year. This means there is no reduction between your home's market value and its assessed value for tax purposes. For example: If your home's market value is $155,000, at Texas's 100% assessment ratio your assessed value would be $155,000, resulting in approximately $2,062 in annual taxes at the county's effective rate of 1.33% (before any exemptions).

The Protest Process

Appeals are heard by the Appraisal Review Board (ARB). The Cameron County ARB hearing is a formal proceeding where you present your evidence to an independent panel. Most cases resolve within 2-4 months from filing, with simple cases potentially settling in 30-45 days through informal review. Homeowners who file protests will have access to the district's evidence packet through the online portal before their hearing.

1

Step 1: Review your Notice of Appraised Value carefully when it arrives (typically mailed beginning April 6th). Note the property ID, proposed value, notice date, and protest deadline.

2

Step 2: Search your property on the Cameron CAD website to verify the appraisal details, exemptions, and property characteristics. Save a copy of your property record for your evidence packet.

3

Step 3: Gather strong evidence to support your protest, including comparable sales of similar properties in your neighborhood, photos showing property condition or defects, repair estimates for any damage, and documentation of any incorrect property details (square footage, age, features).

4

Step 4: File your protest before the deadline using the Cameron CAD online portal, drop box, or mail. Clearly state your grounds for protest (market value too high, unequal appraisal, or incorrect property details) and your requested value.

5

Step 5: Attend the informal review if offered by Cameron CAD to discuss your evidence with an appraiser. Many protests are resolved at this stage without needing a formal hearing.

6

Step 6: If the informal review doesn't resolve your protest, prepare for your formal Appraisal Review Board (ARB) hearing. Present your evidence clearly and professionally, focusing on comparable sales and property-specific issues.

7

Step 7: If you disagree with the ARB's decision, you can appeal to state district court, request binding arbitration (for certain property values), or appeal to the State Office of Administrative Hearings (SOAH) depending on your property type and circumstances.

Required form: Notice of Protest form (available online) or written letter of disagreement

Frequently Asked Questions

What is the deadline to protest my property taxes in Cameron County for 2026?
The deadline to file your property tax protest in Cameron County is May 15, 2026, or 30 days from the date your Notice of Appraised Value was mailed by Cameron CAD, whichever date is later. Homestead properties typically receive notices by April 1, while other properties receive notices by May 1. If the deadline falls on a Saturday, Sunday, or legal holiday, it automatically extends to the next business day. Missing this deadline means you lose your opportunity to protest for the 2026 tax year, though late protests may be accepted in rare cases involving clerical errors or substantial mistakes.
How do I file a property tax protest online in Cameron County?
You can file your Cameron County property tax protest online through the Cameron CAD Public Portal at cameron.prodigycad.com. The online system is fast and easy, providing instant confirmation of your filing. Simply search for your property, select the protest option, choose your grounds for protest (such as market value too high or unequal appraisal), state your requested value, and upload supporting evidence like comparable sales or photos. The online portal also allows you to track your protest status, access the district's evidence packet, and receive communications via email throughout the process.
What is the homestead exemption worth in Cameron County?
In Cameron County, the school district homestead exemption is worth $140,000 for the 2026 tax year, which was increased from $100,000 under Proposition 13 approved by Texas voters in November 2025. This exemption removes $140,000 from your home's taxable value for school district taxes only. On a home valued at $250,000, this exemption would reduce your taxable value to $110,000 for school taxes, potentially saving you hundreds to over a thousand dollars annually depending on your local school tax rate. Homeowners age 65 or older, or those with qualifying disabilities, receive an additional $60,000 exemption for a combined total of $200,000.
What happens at an ARB hearing in Cameron County?
At a Cameron County Appraisal Review Board (ARB) hearing, you present your evidence to an independent panel that decides whether to adjust your property's appraised value. The hearing is a formal proceeding where you explain why you believe your property is overvalued, using evidence such as comparable sales, photos of property condition, or documentation of incorrect property details. The Cameron CAD appraiser will also present their evidence supporting the appraised value. Keep your presentation short, factual, and document-based, focusing on specific evidence rather than general complaints. After reviewing both sides, the ARB issues a written Order of Determination by certified mail with their decision.
How much can I save by protesting my property taxes in Cameron County?
The amount you can save by protesting depends on how much your property is overvalued and your local tax rate. In Cameron County, approximately 60-70% of property tax protests result in some reduction, with professional services achieving success rates above 85%. The average reduction ranges from 8-15% of assessed value when successful. On a typical Cameron County home valued at $155,094 with the county's effective tax rate of 1.33%, a 10% value reduction would lower your assessed value by about $15,509, saving approximately $206 annually. Over several years, these savings compound significantly, making the protest process worthwhile even for modest reductions.
What evidence do I need for a Cameron County property tax protest?
The strongest evidence for a Cameron County property tax protest includes recent comparable sales of similar properties in your neighborhood that sold for less than your appraised value, photos documenting property condition issues or damage, contractor repair estimates for any needed work, and documentation proving incorrect property details like wrong square footage or features. Cameron CAD will provide their own evidence packet through the online portal once you file your protest, which you should review before your hearing. Focus on property-specific evidence rather than general complaints about high taxes. The most effective protests use actual market data showing that your property's value is higher than what similar homes are selling for in your area.
Can I protest my Cameron County property taxes if I have a homestead exemption?
Yes, absolutely. Having a homestead exemption does not prevent you from protesting your property's appraised value, in fact, homestead properties in Cameron County benefit from a 10% annual cap on assessed value increases, but you can still protest if you believe the initial value is too high. The homestead exemption and property tax protest are two separate tools that work together to lower your tax bill. The exemption reduces your taxable value by $140,000 for school taxes, while a successful protest lowers the appraised value itself. Many Cameron County homeowners use both strategies simultaneously to maximize their savings and ensure they're not overpaying on their property taxes year after year.
Does Cameron County offer an informal review before the formal ARB hearing?
Yes, Cameron County Appraisal District offers an informal review process where you can meet with an appraiser to discuss your evidence and potentially resolve your protest without going to a formal Appraisal Review Board hearing. Most cases in Cameron County are settled through informal review before requiring an ARB hearing, and simple cases may resolve within 30-45 days if the appraisal district agrees to an adjustment. During the informal review, you present your evidence and the appraiser may offer a settlement value. If you accept the offer, your protest is resolved quickly. If you don't accept the settlement or the appraiser won't adjust the value, your case proceeds to a formal ARB hearing where an independent panel makes the final decision.
