Texas Property Tax Protest Deadlines: Why the Notice Date Controls

Texas does not have one deadline that accurately describes every property-tax protest. The Texas Comptroller states that the usual deadline is May 15 or 30 days after the appraisal district mails the Notice of Appraised Value, whichever is later. Special subjects and circumstances can have different rules.

Source review: August 13, 2026. Property-tax rules and account-specific dates can change. The homeowner's current notice and the responsible appraisal district control.

What the usual rule means

For many 2026 notices, May 15, 2026 was the usual calendar date. But the mailing date on the property owner's notice can produce a later deadline. A generic article headline should never replace the deadline printed on the current notice or the responsible appraisal district's current filing instructions.

The controlling record for a specific property should include:

• the tax year and property account;
• the date the appraisal district says it mailed the notice;
• the deadline printed on the notice;
• the protest subject or subjects selected; and
• the appraisal district's accepted filing methods and confirmation.

How a notice of protest can be filed

The Comptroller provides Form 50-132, Property Owner's Notice of Protest. The Comptroller also explains that a property owner is not required to use that form if the written notice otherwise identifies the property, the owner, and a subject showing dissatisfaction with an appraisal-district decision. Local online, mail, delivery, and electronic procedures vary, so the appraisal district's current instructions control the submission method.

Keep proof of submission. A completed form sitting on a computer is not evidence that the appraisal district received it.

Late and special situations require the actual rule

The Comptroller describes limited late or special protest paths, including good cause, failure to receive a required notice, certain military or offshore-work circumstances, and specified correction procedures. Each path has its own conditions and timing. The existence of a possible late procedure does not establish that a particular owner qualifies.

If the ordinary deadline appears to have passed, the responsible next step is to read the current Comptroller guidance, the local ARB procedures, and the account-specific notice. Missing or conflicting information should be surfaced rather than guessed.

Evidence and hearing timing

After a protest is filed, the ARB sends hearing information. The Comptroller says the notice generally includes the date, time, place, subject matter, and information about estimated taxes at least 15 days before the hearing. Local hearing procedures can govern copies, electronic presentation, scheduling, and evidence handling.

Potential evidence may include property photographs, comparable-property information, repair receipts or estimates, sales documents, surveys, engineering reports, deed records, and unequal-appraisal calculations where that argument applies. Relevance and source attribution matter more than a generic volume of documents.
