Missing a property tax deadline in Texas can seriously limit your ability to challenge an assessed value. This evergreen deadline hub explains the deadline to protest property taxes in Texas, the property tax protest deadline Texas owners commonly search for, and how county-specific timing issues may affect the next step.
The general statewide rule is important, but your actual deadline may depend on when the appraisal district sent your notice, what kind of challenge you are filing, and whether you are still in the protest stage or evaluating appeal options after an Appraisal Review Board decision.
In many Texas property tax cases, owners generally must file a protest by May 15 or within 30 days after the appraisal district delivers the notice of appraised value, whichever is later. Always review your actual notice because deadline rules can vary by situation.
Many owners search for the Texas property tax protest deadline 2026 after receiving a new notice of appraised value. For the 2026 tax year, the key practical point is still to review your actual appraisal notice immediately and confirm the filing instructions and due date shown by the appraisal district.
In many cases, the deadline is tied to May 15 or 30 days after the notice is delivered, whichever is later. However, some circumstances may involve different timing, so owners should not rely only on memory from prior years or general deadline articles.
The May 15 deadline is the date many Texas property owners associate with filing a property tax protest. Because notice timing matters, the applicable deadline may be later than May 15 if the appraisal district delivered the notice after the normal schedule.
If you are close to the deadline, the first priority is preserving your right to protest. Evidence, negotiation, and hearing preparation can often continue after filing, but missing the filing deadline can reduce or eliminate normal protest options for that tax year.
The property tax protest process is deadline-driven. If you miss the filing window, you may lose the chance to challenge the appraised value through the normal process for that tax year.
The deadline framework is generally statewide, but county searches matter because property owners often look for local appraisal district guidance. The table below links county deadline intent back to the relevant county pages and the broader protest or appeal process.

Appeal options may come later if the dispute is not fully resolved through the appraisal district or Appraisal Review Board process.

Check the market value, assessed value, exemption details, filing deadline, hearing information, and property record information.
The value may be too high, unequal compared with similar properties, or based on inaccurate property data such as square footage, condition, classification, or exemption status.
Filing before the deadline preserves your right to challenge the appraisal district value. Do not wait until all evidence is perfect before confirming that the protest itself has been filed on time.
Comparable sales, condition photos, repair estimates, independent appraisals, market data, and unequal appraisal support may all be useful. Commercial owners may also need income, expense, vacancy, and rent roll information.
Some owners handle the filing themselves, while others seek guidance earlier to avoid weak submissions, missed opportunities, or poor appeal positioning.
County-specific deadline searches are useful, but your actual deadline depends on the notice and circumstances. Do not rely only on memory, prior-year assumptions, or a generic date without checking the current notice.
Use these county pages for local appraisal district guidance, protest process information, and county-specific internal links from this deadline hub.

In many cases, owners generally must file by May 15 or within 30 days after the appraisal district delivers the notice of appraised value, whichever is later. The exact timing depends on the notice and circumstances.
For 2026, many owners will still focus on the May 15 deadline or the 30-day notice rule, whichever is later. Always confirm the specific date on your appraisal notice and county filing instructions.
Not always. The protest deadline is usually the first filing deadline to challenge the appraised value. Appeal options may come later and can have separate deadlines depending on the procedure involved.
The general framework is similar statewide, but county-specific searches are common because owners want local guidance based on their notice, appraisal district, filing portal, and hearing process.
Review the notice immediately, file before the listed deadline, save confirmation records, and begin organizing your evidence as soon as possible.
In many situations, filing preserves your right to challenge the value, and evidence preparation continues after filing. Owners should still confirm local requirements and submission deadlines for evidence or hearings.
