Texas has no state property tax. All 254 counties administer their own appraisal districts, set their own methodologies, and make their own valuation decisions. That level of local control is a feature of how this state is built — but it also means there are 254 separate systems that need oversight. That’s the job of the Property Tax Assistance Division.
What PTAD Is
The Property Tax Assistance Division (PTAD) is a department within the Texas Comptroller’s Office. It doesn’t collect taxes, set rates, or determine your property’s value. What it does is monitor whether the 254 appraisal districts around the state are doing their jobs consistently and in compliance with Texas law.
What PTAD Does
Property Value Study (PVS). Every two years, PTAD conducts a study of property values in each school district to determine whether the local appraisal district’s values are accurate relative to actual market conditions. This matters because school district funding from the state is tied to property values — if a district undervalues property, it may receive more state funding than it’s entitled to. If it overvalues property, homeowners pay more than their share.
Methods and Assistance Program (MAP) Reviews. Also every two years, PTAD reviews appraisal districts for operational compliance — whether they’re following proper appraisal methods, serving taxpayers adequately, and meeting state standards. These reviews produce public reports.
Education and guidance. PTAD publishes the Property Taxpayer Bill of Rights, the Taxpayer Assistance Pamphlet (which you’re entitled to receive before your ARB hearing), and updated property tax law summaries after each legislative session. These are real resources, available at no cost.
Taxpayer Assistance Pamphlet. If you are going to an ARB hearing, you are legally entitled to a free copy of this pamphlet from the Comptroller’s office. Request it. Know what the ARB is and isn’t allowed to do before you walk in.
PTAD Resources Worth Knowing
The Texas Comptroller’s property tax page at comptroller.texas.gov publishes the Taxpayer Assistance Pamphlet, the Property Taxpayer Bill of Rights, and property tax law updates. These are not bureaucratic boilerplate — they contain your statutory rights, spelled out plainly.
What PTAD Does Not Do
PTAD does not intervene in individual property tax disputes. If your appraisal district overvalued your home, PTAD will not fix it. If your ARB hearing went badly, PTAD has no jurisdiction to overturn the result. Its oversight is systemic — it looks at districts as a whole, not at individual accounts.
This is a meaningful limitation. A district can overvalue individual properties consistently, pass a MAP review, and score fine on the PVS — because those measures look at aggregate accuracy, not at whether your specific home was appraised fairly. The oversight exists. It is not sufficient on its own. Your protest is the mechanism that protects you individually.
“All political power is inherent in the People, and all free governments are founded on their authority, and instituted for their benefit.”
— Section 2, Declaration of Rights, Republic of Texas, 1836PTAD is a useful watchdog with real limitations. Know what it publishes, use the resources it provides, and understand that the accountability it offers operates at the system level. At the individual level — your property, your value, your tax bill — the accountability runs through you. File the protest. Show up to the hearing. Make them prove the number.
