We check whether a protest will actually lower your tax bill, after caps and exemptions, before you pay. If it will, we mail you a ready-to-sign kit with a return envelope addressed to the Cameron County Appraisal District — a flat $89. You sign it and mail it. No percentage of your savings.
To protest your Cameron County property taxes in 2027, send a Notice of Protest (Form 50-132) to the Cameron County Appraisal District by May 17, 2027 — or within 30 days of your appraisal notice, whichever is later. Include evidence that your home is valued above market or above similar homes. Protests are authorized under Texas Tax Code §41.41. TaxAppeal USA checks first whether a protest will actually lower your tax bill. If it will, we mail you a ready-to-sign protest kit for a flat $89 — you sign it and mail it. No percentage of your savings.
We hold Cameron County's certified 2026 appraisal roll. Every figure below is counted directly from it — 123,574 single-family homes, the district's own numbers. Nothing here is estimated or averaged in from another county.
45.4% of Cameron County homes are held below market by a cap — a high share, and the single most common reason a Cameron County protest wins on paper and saves nothing. Market value has to fall past the capped value before a dollar reaches the bill. Texas caps how fast a homestead's taxable value can rise — 10% a year under Tax Code § 23.23, and 20% on most non-homestead property under § 23.231. We check where your property sits against that cap before you pay us, and we tell you when the answer is that a protest would not move your bill.
The median Cameron County home on the roll is 1,376 square feet — a compact home. On a smaller house each square foot carries more of the value, so the district's recorded living area is the first figure worth checking: a measurement that is off by a hundred feet shifts the per-foot comparison more here than it would on a larger home.
The median Cameron County value divided by the median home size comes to roughly $130 a square foot. That is a moderate per-foot level. A home valued $10 a foot above its comparables would sit about 7.7% over them — a gap that is visible in the district's own numbers without any appraisal of our own.
This is the question an equal-and-uniform protest turns on. Texas Tax Code § 41.43(b)(3) does not ask whether your home is worth what the district says — it asks whether your home is appraised equally with comparable properties. So what matters is how much the district's own values disagree with each other.
Across 1,485 Cameron County neighbourhoods, the typical home's appraised value per square foot sits 17.5% away from the median for its own neighbourhood. That is a wide spread. Similar Cameron County homes in the same neighbourhood carry appraised values that differ substantially from one another, which is the precise circumstance § 41.43(b)(3) was written for, and it makes the median-of-comparables argument unusually strong here.
The median Cameron County home was built in 1994, so the county holds a mix of established neighbourhoods and newer construction — and a mass-appraisal model tends to handle the two with different accuracy.
One more feature of this roll shapes every Cameron County protest: the district divides 123,574 homes into 3,300 separate neighbourhood codes — about 37 homes each. That is unusually fine-grained. It means the properties the district itself considers comparable to yours are genuinely close by and genuinely similar, which makes the comparison persuasive — but it also means there may only be a handful of them, so which ones are selected matters a great deal.
Measured over every state-class A home with recorded living area, in neighbourhoods of at least 10 homes, using the appraised values on the district's certified 2026 roll. Texas does not disclose sale prices, so this compares the district's values to each other rather than to the market — which is what § 41.43(b)(3) compares too.
