We write your protest letter, pull comparable sales in Harris County, and send it via trackable USPS mail to the Harris Central Appraisal District — all for a flat $89. No percentage of your savings. No hidden fees.
To protest your Harris County property taxes in 2027, file a Notice of Protest (Form 50-132) with the Harris Central Appraisal District by May 17, 2027 — or within 30 days of your appraisal notice, whichever is later. Include comparable sales showing your home is overassessed. Protests are authorized under Texas Tax Code §41.41. TaxAppeal USA writes and certified-mails your protest for a flat $89 — no percentage of your savings.
We hold Harris County's certified 2026 appraisal roll. Every figure below is counted directly from it — 1,146,413 single-family homes, the district's own numbers. Nothing here is estimated or averaged in from another county.
12.6% of Harris County homes are held below market by a cap. For those owners a protest has to push market value past the capped value before the bill moves at all — the first slice of any reduction changes the notice and nothing else. 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.
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 5,512 Harris County neighbourhoods, the typical home's appraised value per square foot sits 10.1% away from the median for its own neighbourhood. That is a fairly tight spread, though not so tight that outliers do not exist. Most Harris County homes sit close to their neighbours; the ones that do not, stand out clearly.
The median Harris County home was built in 1990, 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.
The district divides 1,146,413 Harris County homes into just 5,842 neighbourhood codes — around 196 homes each. These are broad groupings, which cuts both ways. There is no shortage of comparables, but a single Harris County neighbourhood code can span streets that are not much alike, so the properties the district treats as equivalent to yours may not be. Selecting the ones that genuinely match is most of the work.
Measured over every state-class A1 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.

File My Protest — $89 Flat →TaxAppeal USA is a self-service document-preparation and mail filing service. In every state we serve, including Florida, we are not property tax consultants, agents, or representatives, we do not provide tax or legal advice, and we do not represent customers before any appraisal district, board of equalization, value adjustment board, or review board. Every protest and petition is prepared for the property owner, signed by the owner, and filed in the owner’s name. In Florida we also pay your county’s Value Adjustment Board filing fee on your behalf and mail your petition to the Clerk of the Value Adjustment Board. Your petition is signed by you as the property owner under section 194.011(3), Florida Statutes. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
