If you own a home in Schertz or Cibolo, your property tax notice deserves a careful look before the May 15 protest deadline.

Many homeowners glance at the appraised value, compare it to last year, and either feel relieved or frustrated. But the number itself is only part of the story. You also want to check your exemptions, property details, neighborhood sales, and whether your home is being compared fairly.

That is especially true in Schertz and Cibolo, where homes can vary widely by age, subdivision, school district, county, tax entities, lot size, condition, and proximity to Randolph AFB, I-35, FM 78, Loop 1604, and New Braunfels.

In Texas, the usual deadline to file a property tax protest is May 15 or 30 days after the appraisal district mailed your notice, whichever is later. Guadalupe Appraisal District lists the 2026 protest deadline as May 15, 2026 for non-business personal property properties. Bexar County also notes that the deadline each year is May 15 or 30 days after the notice is mailed, whichever is later.

First, confirm which county applies

One thing that can confuse Schertz and Cibolo homeowners is that the area does not fall neatly into one simple bucket.

Depending on the specific property, you may be dealing with:

Guadalupe County
Bexar County
Comal County in some nearby areas
Different school districts
Different city tax entities
Different special districts or fees

Your appraisal notice should identify the appraisal district and taxing entities tied to your property. This matters because deadlines, online portals, protest procedures, and values are handled through the applicable appraisal district.

If you recently moved to Schertz or Cibolo, or if you own a home near a county line, do not assume your neighbor’s process is exactly the same as yours. Check your actual notice.

Review your appraised value

The first number most homeowners look at is the appraised value.

Ask yourself:

Did the value increase significantly from last year?
Does the value seem higher than similar homes nearby?
Were recent sales in your neighborhood truly comparable?
Does the value reflect your home’s actual condition?
Are you being compared to updated homes when yours needs repairs?
Are you being compared to larger or newer homes?

Schertz and Cibolo have many neighborhoods where small differences can matter. A home with fresh updates, newer systems, and strong curb appeal may not compare directly to a similar-sized home that needs flooring, paint, roof work, HVAC updates, or landscaping repairs.

Check your exemptions

Do not skip the exemption section.

Common exemptions may include homestead, over-65, disabled person, disabled veteran, or other qualifying exemptions. Not every homeowner qualifies for every exemption, but if you do qualify, you want to make sure it is reflected correctly.

Your appraised value and taxable value may not be the same. The appraised value reflects the district’s opinion of value, while exemptions and caps may affect how much of that value is actually taxable.

If something looks wrong, contact the appraisal district or review the district’s exemption resources.

Look closely at property details

Mistakes happen.

Before deciding whether to protest, check the property characteristics on your notice or appraisal district record.

Review:

Square footage
Year built
Lot size
Bedrooms and bathrooms
Garage spaces
Pool or no pool
Exterior features
Condition assumptions
Additional structures
Ownership information
Exemptions
Property classification

If the record shows incorrect details, that may affect the appraised value. For example, if your home is listed with more square footage than it actually has, or if an improvement is recorded incorrectly, it may be worth addressing.

Compare by neighborhood, not just city

A common mistake is comparing your home to “Schertz” or “Cibolo” broadly.

That is usually too general.

A home in one Schertz neighborhood may not compare well to a home in another, especially if there are differences in age, school zoning, builder, lot size, tax rate, updates, or proximity to major roads.

The same is true in Cibolo. Some areas are newer, some are more established, some have larger lots, and some compete heavily with nearby new construction.

Better comparisons usually start with:

Same subdivision or nearby neighborhood
Similar size
Similar age
Similar lot size
Similar condition
Similar updates
Similar school district
Recent sale date
Similar features

This is where local sales data matters.

Understand condition and updates

The county may not fully know the condition of your home.

If your home needs repairs, has older flooring, has an aging roof, needs paint, has foundation concerns, has older HVAC, or has dated finishes, that may matter when comparing it to recent sales.

On the other hand, if nearby homes that sold for more had major updates, new flooring, fresh paint, remodeled kitchens, newer roofs, or premium outdoor spaces, those may not be fair comparisons to your home.

When reviewing your notice, think like a buyer:

Would a buyer pay the same for your home as they would for the comparable home?
What updates did that comparable home have?
Was it move-in ready?
Did it include features your home does not have?
Was it in the same neighborhood or a different part of town?

A fair protest review is not just about finding lower sales. It is about finding relevant sales.

Why Schertz and Cibolo values can vary

Schertz and Cibolo have strong buyer demand for several reasons. The area is popular with families, military relocation buyers, commuters, and people wanting access to Randolph AFB, San Antonio, New Braunfels, I-35, FM 78, and Loop 1604.

But values are not the same everywhere.

Value can shift based on:

Subdivision
School zoning
Commute routes
New construction competition
Lot size
HOA fees
Taxing entities
Age of home
Condition
Neighborhood amenities
Proximity to Randolph AFB
Access to shopping and dining
Resale demand

That is why homeowners should not assume a citywide number tells the whole story.

What to do before May 15

Before the deadline, take these steps:

Read your appraisal notice carefully
Confirm the protest deadline listed on your notice
Verify your exemptions
Check your property details
Review your appraised value and taxable value
Look at recent nearby sales
Compare condition, updates, age, and lot size
Gather photos or documents if your home has condition issues
File on time if you decide to protest
Consider getting professional help if you are unsure

If you miss the deadline, you may lose the right to protest for that year unless a limited exception applies. The Texas Comptroller explains that late protest rights are limited and generally require good cause.

Bottom line

For Schertz and Cibolo homeowners, the May 15 property tax protest deadline is a good reminder to slow down and review your notice carefully.

Your appraised value may be reasonable, too high, or simply based on comparisons that do not fully reflect your home’s condition, location, or features. The only way to know is to review the details.
