What homeowners need to know before May 15

If you own a home in Bexar County, the 2026 property tax protest deadline is approaching quickly. Miss it, and you are essentially accepting the county’s value for the year with very limited options to challenge it.

As of March 23, 2026, you have 53 days left to file.

That might sound like plenty of time, but most homeowners still do not take advantage of it. In 2024, over 80% of Bexar County homeowners did not file a protest, leaving an estimated $100M+ in potential tax savings on the table. Many either assume it is not worth it or do not realize how the process works.

The Actual Deadline Rule

The deadline is not just May 15. It follows a simple rule under Texas law:

May 15, 2026 OR 30 days after the date on your Notice of Appraised Value, whichever is later.

If your notice is dated later in April, your deadline may extend beyond May 15. The key is to check the date printed on the notice itself, not when it arrives.

Why Filing a Protest Is Worth It

A lot of homeowners hesitate because they assume the outcome is uncertain or not worth the effort. The data says otherwise.

In Bexar County, the vast majority of informal protests result in a reduction, and most cases never make it to a formal hearing. The average reduction has been around $15,000 to $20,000 in value, which can translate to roughly $400–$600 per year in tax savings, depending on your tax rate.

Just as important, there is no risk to filing. Under Texas law, your assessed value cannot increase as a result of protesting. The only outcomes are a reduction or no change.

Understanding Your Two Protest Angles

When you file, you are not locked into one argument. There are two main ways to challenge your value, and they work independently.

The first is market value, which is based on what similar homes have actually sold for. If your home would not realistically sell for what the county says, this is your argument.

The second is unequal appraisal, which compares your home to similar properties nearby. If similar homes are assessed lower, even if values are close overall, you may still have a case.

Most homeowners should select both when filing. It gives you more flexibility when reviewing evidence and negotiating.

How to File Your Protest

Filing is more straightforward than most people expect and can usually be done in under 10 minutes.

You will need:

• Your Owner ID and PIN (from your Notice of Appraised Value)
• Your property address
• Your protest selections

When filing, most homeowners should check:

• Incorrect market value
• Unequal value

You can file in three ways:

Online (fastest option): through the BCAD portal using your Owner ID and PIN
By mail: using Form 50-132
In person: at the BCAD office

Online filing is typically preferred because you get immediate confirmation and can track your case.

What Strengthens a Protest

Filing gets you in the door. Evidence is what actually drives the result.

Strong protests typically include:

• Recent comparable sales showing lower values
• Photos of the home showing condition or needed repairs
• Estimates for repairs or updates
• Nearby homes with lower assessed values

Many homeowners skip this step or do not go deep enough, which is where most missed opportunity happens.

What Happens After You File

Once your protest is submitted, the process usually moves into an informal hearing. This is typically done over the phone or Zoom with a county appraiser.

This stage resolves the majority of cases. The appraiser reviews your evidence and may offer a value reduction. If you agree, the process ends there.

If not, the case moves to a formal hearing with the Appraisal Review Board. These are shorter, more structured, and based strictly on evidence.

What Happens If You Miss the Deadline

If you miss the deadline, your options become limited.

There is a short window where you may be able to file late with “good cause,” but this requires a valid reason and is not guaranteed. It also must be filed on paper, not online.

Once records are finalized, you lose the ability to protest for the year entirely.

Why 2026 Matters More Than Most Years

There are a few factors that make this year more important than usual.

The homestead exemption has increased to $140,000, which lowers your taxable value. However, your assessed value still matters because it affects future caps and calculations. Lowering your value now can have a longer term impact.

At the same time, the local market has shifted. Inventory is higher, homes are sitting longer, and many are selling below list price. In some cases, there is a gap between assessed values and actual sales, which creates opportunity for protest.

Why Filing Early Matters

Many homeowners wait until the last few days to file, but timing can affect the outcome.

Filing early gives more time to gather comparable sales and build a stronger case. The filing itself is quick, but the preparation is what determines the result.

What to Take Away

The process is not complicated, but the deadline is firm. If you plan to challenge your property value, the most important step is getting it filed on time.

From there, it becomes a matter of supporting your case with real data and understanding how your home compares to the current market.

How I Can Help

If you are unsure how to approach your protest or just do not want to spend time dealing with it, I can step in and help. From analyzing your value to building a case with comparable sales and handling negotiations, the goal is to make sure you are not overpaying simply because you missed something.
