Tax firms typically charge 25%-50% of your savings, every year. Here are the real 6 steps to protest yourself and keep 100% of what you save — with the law that backs your right to go it alone.
Check your home FREE →Every spring, Harris County homeowners get letters and calls from firms offering to "handle" their property tax protest for them. What most of those letters don't say plainly is that the law already gives you, the homeowner, the direct right to do exactly the same thing — without paying anyone a percentage of your savings, every year, indefinitely. This page walks through that right, what an "agent" actually is, the honest economics of hiring one versus doing it yourself, and the six concrete steps of the process.

Texas Tax Code §41.41(a) states that "a property owner is entitled to protest before the appraisal review board" a specific list of actions — including the determination of the appraised value of their property, unequal appraisal, and denial of an exemption. This is not a right that depends on hiring representation: it is a right the law gives directly to you as the property owner. §23.01(g) confirms the same idea from another angle: "property owners representing themselves are entitled to offer an opinion of and present argument and evidence" about the value of their property. There is no license, credential, or formal training required to exercise this right.
A property tax agent is a person or firm a property owner formally designates, under Tax Code §1.111, to act on their behalf in property tax matters. That designation isn't informal — it requires filling out the Comptroller's Form 50-162 ("Appointment of Agent for Property Tax Matters"), signing it, and filing it with the appraisal district before it takes effect. Without that form on file, no one — not a firm, not a relative, not a neighbor — can legally protest on your behalf with HCAD.
Here's the part most sales letters don't emphasize: §1.111(g) itself says, word for word, that "an appraisal district, appraisal review board, or taxing unit may not require a person to designate an agent to represent the person in a property tax matter." Appointing an agent is a choice you can make — never a legal requirement to protest, file an exemption, or attend a hearing.
According to a Texas property tax protest industry cost breakdown published in 2026, most protest firms charge between 25% and 50% of your first-year savings as a contingency fee. One of the highest-volume firms operating in the Houston area specifically charges a flat 50% contingency fee. That fee isn't a one-time charge — if the firm keeps representing your property year after year, that same percentage repeats every year it achieves a reduction, and many contracts renew automatically unless you cancel in writing — always read the renewal terms before signing anything.
A simple example: if a value reduction saves you $1,250 in a year, a firm charging a 40% fee keeps $500 and you keep $750. At a 50% fee, you keep only $625. Doing the same protest yourself — with the same public HCAD evidence any firm would use — you keep 100% of that savings, every year, with no automatic renewals to worry about.
The Appraisal Review Board (ARB) is a group of local residents — typically a three-person panel — appointed to resolve disputes between property owners and the appraisal district; they are not HCAD employees. Per the Texas Comptroller's own ARB page, hearings "typically occur in May through July," and larger districts may continue hearings beyond July. The hearing is informal compared to a courtroom: you present your evidence (for example, comparable properties from HCAD's own records), the HCAD appraiser presents theirs, and the three-person panel decides. There are no formal courtroom rules of evidence, and the Comptroller's office itself publishes a video guide, "How To Present Your Case at an ARB Hearing: A Homeowner's Guide," built specifically for people without a lawyer or agent.
