Hays County has become one of the fastest-growing counties in Texas, with San Marcos, Kyle, Buda, and Dripping Springs absorbing the overflow from Austin’s housing market. Median home values have climbed past $400,000, and the Hays Central Appraisal District (Hays CAD) has pushed appraisals upward to keep pace with the market. The result is a wave of over-assessments on homes that did not actually track the trend in their specific neighborhood.
The encouraging news: Hays County protesters have one of the highest success rates in Texas. Hays CAD reports that a large majority of formal protests result in a reduction, and informal settlements push that rate even higher. This guide walks you through the entire process, from reading your appraisal notice to presenting evidence at your ARB hearing.
The Hays Central Appraisal District is responsible for appraising every residential and commercial property in Hays County. Hays CAD serves San Marcos, Kyle, Buda, Dripping Springs, Wimberley, and the unincorporated areas, as well as the school districts and other taxing jurisdictions that use its appraisal roll.
Hays CAD uses mass appraisal, meaning it applies area-wide sales trends and comparable data to estimate values for every property at once. That method produces reasonable averages but often misses property-specific factors such as foundation problems common in the limestone and clay soils of the Hill Country, flood zone designations along the Blanco and San Marcos rivers, or unequal appraisals compared with neighboring homes. Those gaps are exactly what a protest corrects.

The standard Texas protest deadline is May 15, or 30 days after Hays CAD mails your Notice of Appraised Value, whichever is later. Hays CAD typically mails notices between late March and mid-April, so depending on when your notice was mailed, your personal deadline could extend into late April or early May.
Check the “Date Mailed” printed on your notice, not the date it arrived in your mailbox. If your notice was mailed on April 18, your deadline is May 18 (30 days later), not May 15. This distinction saves many homeowners who think they missed the window.
File early if you can. Hays CAD’s online system sees heavy traffic near the deadline, and early filers get earlier hearing dates, which means your protest is resolved sooner and with less uncertainty.
Hays CAD offers three filing methods. Online filing is the fastest and creates an instant confirmation record.
Hays CAD’s online protest portal lets you file without leaving your house. You will need your property ID number (printed on your notice) and a valid email address. The system walks you through selecting your protest reason, entering your opinion of value, and uploading supporting evidence. You receive an email confirmation immediately after filing.
Download and complete Form 50-132 (Notice of Protest) from the Texas Comptroller’s website. Mail it to Hays CAD before the deadline. The postmark date counts as your filing date, so use certified mail to create proof of timely filing.
You can deliver your completed Form 50-132 to the Hays CAD office in person. Visit the Hays County data page for the current office address and hours.
When filing, select “Value is over market value” as your primary protest reason. You can also check “Value is unequal compared with other properties”. This gives you two separate legal arguments at your hearing and roughly doubles your chances of success.

Evidence wins protests. Opinions, complaints about tax rates, and personal financial hardship do not move the needle at Hays CAD. The appraisal district and ARB panel are required to base decisions on market data, so your job is to present data that supports a lower value. Here is what works in Hays County.
Find 3–5 recent sales of homes similar to yours that sold for less than Hays CAD’s appraised value. Texas uses a 100% assessment ratio, so sale prices compare directly to your appraised value with no adjustment. Focus on homes in your subdivision or neighborhood that match your square footage, year built, lot size, and condition. Prioritize recent sales, a home that sold six months ago is more persuasive than one from 14 months ago. Read our complete guide to finding comparable sales for step-by-step instructions.
Texas Property Code Section 42.26 lets you argue that your property is appraised higher per square foot than comparable properties on Hays CAD’s own rolls. Pull the appraised values and square footage of 5–10 similar homes in your area, calculate each one’s price per square foot, and show that yours is above the median. This argument is especially effective in Kyle and Buda, where newer tract-home neighborhoods have similar properties valued inconsistently.
Hays CAD cannot inspect the interior of every home. If your property has issues that reduce its value, foundation problems (common in the limestone and clay soils across Hays County), an aging roof, outdated HVAC or plumbing, water damage, or deferred maintenance, document them with photos and repair estimates from licensed contractors. A $20,000 foundation repair estimate directly supports a $20,000 reduction argument.
After you file your protest, Hays CAD will schedule you for two stages: an informal settlement conference and, if needed, a formal Appraisal Review Board (ARB) hearing.
This is a one-on-one meeting (in person, by phone, or by video conference) with a Hays CAD appraiser. The appraiser has authority to offer a reduced value on the spot. Bring your evidence organized and ready to present. Be professional and data-focused. The appraiser reviews dozens of cases per day and responds best to clear, factual arguments.
If the appraiser offers a value you find acceptable, you can sign a settlement agreement and your protest is resolved. A majority of Hays County protests are resolved at this stage. If you cannot reach agreement, you automatically proceed to a formal hearing.
The Appraisal Review Board is an independent panel of citizens appointed to hear protests. Your hearing typically lasts 15–30 minutes. You present your evidence, the Hays CAD appraiser presents theirs, and the panel makes a binding determination.
If you disagree with the ARB’s decision, you have further options: binding arbitration (for properties under $5 million) or filing suit in district court. For most homeowners, the informal and ARB stages resolve the matter. For more on what to expect, see our guide on what property tax protests cost.
Protesting your Hays County appraisal is not a long shot. The numbers heavily favor homeowners who show up with evidence.
On a $409,000 Hays County home, a 10% reduction saves roughly $900–$1,100 per year in property taxes, depending on your taxing jurisdictions. Over five years, that is $4,500–$5,500 in real savings.

Before you protest your appraised value, make sure you are claiming every exemption you qualify for. Exemptions reduce your taxable value, which directly lowers your tax bill.
Texas provides a $100,000 exemption on school district taxes for your primary residence. You must apply with Hays CAD. It is not automatic. Once granted, it remains in effect until you move. This exemption also triggers the 10% homestead cap, which limits how much your appraised value can increase from year to year for tax purposes.
Homeowners 65 and older qualify for an additional $10,000 school district exemption on top of the general homestead exemption. This also freezes your school district taxes at their current level. Even if your appraised value increases in the future, your school taxes will not go up. Some local taxing units in Hays County offer additional over-65 exemptions. Read our complete guide to the Texas Over-65 exemption for details.
Texas offers property tax exemptions for disabled veterans based on their VA disability rating. The exemption ranges from $5,000 for a 10–29% rating up to a full exemption from all property taxes for veterans rated 100% disabled or receiving 100% disability compensation due to individual unemployability. See our complete guide to the Texas disabled veteran exemption.
Homeowners who receive disability benefits under the Federal Old-Age, Survivors, and Disability Insurance Program qualify for an additional $10,000 school district exemption, similar to the over-65 exemption. This also triggers a school district tax ceiling.
Hays County homeowners have every reason to protest their appraisal. The process is free to file, carries no risk of an increase, and the majority of protesters receive a reduction. Whether you live in San Marcos, Kyle, Buda, Dripping Springs, or Wimberley, the steps are the same: file by the deadline, bring solid evidence, and let the data make your case.
