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 Dallas Central Appraisal District — a flat $89. You sign it and mail it. No percentage of your savings.
To protest your Dallas County property taxes in 2027, send a Notice of Protest (Form 50-132) to the Dallas Central 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 Dallas County's certified 2026 appraisal roll. Every figure below is counted directly from it — 507,406 single-family homes, the district's own numbers. Nothing here is estimated or averaged in from another county.
34.6% of Dallas County homes are held below market by a cap — a high share, and the single most common reason a Dallas 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 Dallas County home on the roll is 1,755 square feet, a mid-sized home. At that size there is usually a deep pool of genuinely similar comparables in the same neighbourhood to measure against.
The median Dallas County value divided by the median home size comes to roughly $182 a square foot. That is a high per-foot level, where much of a home's value can sit in its location and lot. A $10-a-foot difference is only about 5.5% here, so a strong equal-and-uniform case in Dallas County usually rests on larger gaps between homes that are closely matched.
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 3,177 Dallas County neighbourhoods, the typical home's appraised value per square foot sits 11.3% away from the median for its own neighbourhood. That is a middling spread, and it is the range where equal-and-uniform protests do most of their work — enough variation that some homes sit well above their neighbours, on a roll consistent enough that the comparison is hard to argue with.
The median Dallas County home was built in 1974. Older housing stock is where mass appraisal struggles most: renovations, additions, deferred maintenance and condition differences accumulate over decades, and a model working from square footage and year built cannot see any of them. Two houses on one street can be genuinely unalike while the roll treats them as twins.
The district divides 507,406 Dallas County homes into just 3,392 neighbourhood codes — around 150 homes each. These are broad groupings, which cuts both ways. There is no shortage of comparables, but a single Dallas 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 A11 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.

Check My Protest — $89 Kit →TaxAppeal USA is a self-service document-preparation service. We prepare a ready-to-sign appeal kit and mail it to you; you sign it and mail it to the county yourself. 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 file appeals or represent customers before any appraisal district, board of assessors, board of equalization, value adjustment board, or review board. Every appeal, protest and petition is prepared for the property owner, signed by the owner, and mailed by the owner in the owner’s name. In Florida your petition is signed by you as the property owner under section 194.011(3), Florida Statutes, and the county’s Value Adjustment Board filing fee is paid by you directly to the county. TaxAppeal USA does not sign as your representative, does not appear before the Board, and does not present evidence or argument at a hearing.
