Travis BunnTravis Bunn·Updated July 22, 2026

Guadalupe County is located in south-central Texas with Seguin as the county seat. Major population centers include Schertz, Cibolo, Seguin, New Braunfels (partial), Selma, and Marion, with the county's growing connection to the San Antonio metro area driving rapid development. Property tax protests matter significantly here because Guadalupe County has one of the highest property tax burdens in Texas, with a median effective rate of 1.69% compared to the national median of 1.02%. The median home value in Guadalupe County is approximately $288,797, and the median annual property tax bill is $4,783, which is $2,383 higher than the national median of $2,400.

How Guadalupe County Assesses Property

100%of market value

Assessed by: Guadalupe Appraisal District

Assessment cycle: annual

Notices typically mailed: April through mid-May

In Texas, properties are assessed at 100% of market value for property tax purposes. The market value is what your property would sell for in the open market, and this becomes your assessed value. For example, if your home's market value is $288,797 (the county median), at Texas's 100% assessment ratio your assessed value would be $288,797, resulting in approximately $4,881 in annual taxes at Guadalupe County's effective rate of 1.69% before any exemptions are applied.

The Protest Process

Appeals are heard by the Appraisal Review Board (ARB). The ARB hearing is a formal but straightforward process where you present your evidence to an independent panel of board members. You will have the opportunity to explain why you believe your property is overvalued and present supporting documentation such as comparable sales, photos, and repair estimates.

1

Step 1: Review your Notice of Appraised Value when it arrives in April or May to identify your property's assessed value and compare it to recent comparable sales in your neighborhood.

2

Step 2: File your Notice of Protest (Form 50-132) with the Guadalupe Appraisal District by May 15th or within 30 days of receiving your notice, whichever is later. You can file online at portal.guadalupead.org, by mail to 3000 N. Austin St., Seguin, TX 78155, or in person at either the Seguin or Schertz office.

3

Step 3: Gather evidence to support your protest, including comparable sales data from similar properties in your area that sold for less, photographs showing property condition issues, repair estimates for needed work, and documentation of any errors in the appraisal district's property description.

4

Step 4: Attend the informal review with a Guadalupe CAD appraiser (optional but highly recommended). This meeting provides an opportunity to present your evidence and potentially reach a settlement without proceeding to a formal hearing. In 2024, 57% of Guadalupe County protests heard by the Appraisal Review Board resulted in reductions (2024 Guadalupe CAD data).

5

Step 5: If the informal review does not resolve your protest, attend the formal Appraisal Review Board (ARB) hearing where you present your evidence to an independent panel of board members. The ARB hearing is a formal but straightforward process where you can present comparable sales, photos, and other documentation.

6

Step 6: If you disagree with the ARB decision, you can appeal to state district court, request binding arbitration (for properties valued under $5 million), or appeal to the State Office of Administrative Hearings (SOAH) for certain issues.

Required form: Form 50-132 (Notice of Protest) or written letter of disagreement

Frequently Asked Questions

What is the deadline to protest my property taxes in Guadalupe County for 2026?
The deadline to file a property tax protest in Guadalupe County is May 15, 2026, or 30 days after you receive your Notice of Appraised Value from the Guadalupe Appraisal District, whichever date is later. The appraisal district typically mails assessment notices in April through mid-May. Missing this deadline means you lose your right to protest your property value for the 2026 tax year, so it's critical to mark your calendar as soon as you receive your notice. You can file online at guadalupead.org, by mail, or in person at their Seguin or Schertz offices.
How do I file a property tax protest online in Guadalupe County?
To file a property tax protest online in Guadalupe County, visit the Guadalupe Appraisal District online portal at portal.guadalupead.org. You'll need your property account number from your Notice of Appraised Value and basic information about why you believe your property is overvalued. The online system allows you to submit your Notice of Protest electronically and track the status of your appeal. The online filing system provides immediate confirmation, which you should save as proof of your timely filing. Alternatively, you can download Form 50-132 (Notice of Protest) from the Texas Comptroller's website or the district's website and submit it by mail or in person.
What is the homestead exemption worth in Guadalupe County?
The homestead exemption value in Guadalupe County varies by taxing jurisdiction. School districts provide a $140,000 exemption (increased from $100,000 following voter approval of Proposition 13 in November 2025), which translates to approximately $500-$1,800 in annual school tax savings. Guadalupe County provides 1% of the property value with a minimum of $5,000 as an exemption. Cities and other taxing units may offer additional local option exemptions up to 20% of appraised value. The homestead exemption also limits annual assessed value increases to 10%, which provides significant long-term protection against rapidly rising property taxes in fast-growth areas like Schertz and Cibolo.
What happens at an Appraisal Review Board (ARB) hearing in Guadalupe County?
At an ARB hearing in Guadalupe County, you present your evidence to an independent panel of board members who will decide whether to reduce your property's assessed value. The hearing is a formal but straightforward process where you explain why you believe your property is overvalued and present supporting documentation such as comparable sales from similar properties, photographs showing property condition issues, and repair estimates. The ARB requires documentation, and personal opinions without supporting data will result in denial. You typically have 10-15 minutes to present your case. After hearing from both you and the appraisal district representative, the board will make a decision and mail you the results within a few weeks.
How much can I save by protesting my property taxes in Guadalupe County?
The average savings from a successful property tax protest in Guadalupe County is $1,335 per year according to 2024 data. However, individual savings can range from $500 to $3,000 or more annually depending on your property's value and the degree of overassessment. On the typical Guadalupe County home valued near $288,797 at the county's effective tax rate of 1.69%, an over-assessment of even 10% means you are overpaying approximately $488 per year until you protest it. With Guadalupe County's 93% informal success rate, homeowners have an excellent chance of achieving a reduction without even proceeding to a formal ARB hearing.
What evidence do I need for a successful Guadalupe County property tax protest?
For a successful protest in Guadalupe County, you need documented evidence that demonstrates your property is overvalued compared to the market. The strongest evidence includes 3-5 comparable sales from similar properties in your neighborhood that sold for less than your assessed value within the past 6-12 months. Match property type, location, school district, condition, size, acreage, and improvements before using a sale as protest evidence, as fast-growth areas around Schertz, Cibolo, and New Braunfels-area subdivisions may not compare well with older Seguin homes or rural acreage. Also bring photographs showing property condition issues, repair estimates for needed work, and documentation of any errors in the appraisal district's property description such as incorrect square footage or features.
Can I protest my property taxes if I just bought my home in Guadalupe County?
Yes, new property owners in Guadalupe County can and should protest their property taxes if the assessed value exceeds what they paid. If you've recently purchased a property, it's crucial to ensure your home's assessed value is aligned with its current market value. Your purchase price is strong evidence of market value, especially if the sale was recent and at arm's length. By providing your purchase documentation, closing statement, and evidence of comparable market values, you can effectively challenge any discrepancies between your purchase price and the appraised value. This is particularly important in Guadalupe County where the appraisal district's mass-appraisal model may apply broad appreciation rates from new master-planned developments to all properties without accounting for individual circumstances.
Should I attend the informal review before my ARB hearing in Guadalupe County?
Yes, you should absolutely attend the informal review in Guadalupe County before proceeding to a formal ARB hearing. In 2024, 57% of Guadalupe County protests heard by the Appraisal Review Board resulted in reductions (2024 Guadalupe CAD data). The informal review provides an opportunity to meet with a Guadalupe CAD appraiser, present your evidence, and potentially reach a settlement without the time and preparation required for a formal hearing. Many homeowners achieve their desired reduction at this stage, avoiding the formal ARB process entirely. Even if you don't reach full agreement, the informal review helps you understand the appraisal district's position and refine your evidence before the formal hearing.
