Property taxes play a major role in the yearly costs of owning real estate in Texas, and knowing when and how to challenge an incorrect valuation can make a real difference in what you pay. Many property owners receive their appraisal notice without realizing that the timeline for filing a protest is already ticking. Understanding the rules, deadlines, and steps involved helps you stay prepared and prevents you from losing the chance to correct an inaccurate assessment.

Key Dates For Filing Your Property Tax Protest
Understanding the Texas property tax protest deadline is essential for protecting the accuracy of your property valuation. Every year, appraisal notices trigger a specific filing window that property owners must follow to keep their protest rights active. Below is a clear breakdown of the key dates you need to know:
The Standard Deadline: May 15
The most common deadline for filing a property tax protest in Texas is May 15. This date applies to many counties statewide and serves as the anchor point for most property owners. Filing on or before this date helps preserve your right to challenge the assessed value listed in your appraisal notice.
Deadline Based On Appraisal Notice Delivery
If your appraisal district delivers your Notice of Appraised Value after early May, the deadline adjusts. State law allows property owners to file up to 30 days after the delivery date printed on the notice. This rule protects property owners in counties where appraisal notices are sent later than usual.
Why County Variations Matter
Not all counties release appraisal notices simultaneously, which means deadlines often vary across Texas. Property owners should review their mailed notice as soon as it arrives to determine the specific filing date. Marking this date helps prevent accidental delays and gives you more time to prepare essential documents.
The Value Of Early Preparation
Harding and Carbone encourages property owners to begin reviewing their assessments as soon as the annual notice arrives. Early preparation helps you gather evidence, compare properties, and analyze market factors with a clear head rather than rushing at the deadline. Taking action sooner also provides more opportunities to refine your strategy for a stronger protest.

Why You Shouldn’t Miss The Property Tax Protest Deadline
Missing the Texas property tax protest deadline can affect your financial stability for the entire tax year. Once the deadline passes, the value listed on your appraisal becomes final, even if it does not reflect the true market conditions. Below is a detailed look at why this date carries so much weight for property owners:
Locked In For The Year
When the deadline is missed, property owners lose the opportunity to challenge the assessed value of their property. This means the appraisal district’s valuation becomes permanent for that tax cycle. Any errors, inflated figures, or outdated data used in your assessment remain unchallenged until the following year.
Higher Taxes From Overvalued Assessments
Appraisal districts often rely on mass valuation methods that do not always capture the unique characteristics of individual properties. If your property is assessed too high, your taxes will reflect that inflated value. Missing the deadline forces you to pay based on an incorrect figure that could have been lowered through a timely protest.
Impact On Market Based Accuracy
Texas real estate markets can shift quickly, and assessments do not always keep pace with these changes. A protest allows property owners to show relevant sales data or condition issues that justify a lower figure. Without filing on time, there is no way to correct a valuation that does not match current market realities.
Financial Strain For Residential And Commercial Owners
Higher property taxes reduce a homeowner’s disposable income and can add unnecessary pressure to a business’s operating budget. For commercial property owners, inflated taxes can reduce net income and complicate long term planning. Filing before the deadline helps maintain balance in your financial outlook.
Steps To File A Texas Property Tax Protest
Filing a Texas property tax protest involves several important actions that help support your claim for a fair valuation. Each step gives you an opportunity to review, gather, and present information that strengthens your case. Below is a breakdown of the process so you can move through it with clarity:
Review Your Notice Of Appraised Value
Each spring, Texas property owners receive a Notice of Appraised Value from their local Appraisal District. This document lists your assessed value and the official deadline for filing a protest. Identifying the deadline on this notice is essential because it determines how much time you have to prepare your case.
Collect Strong Supporting Evidence
A successful protest relies on evidence that accurately reflects your property’s value. Photos showing needed repairs, recent sales of comparable properties, or an independent appraisal can help demonstrate that the assessed value is too high. The goal is to create a clear picture of your property’s condition and market position.
Submit Your Protest Form
Texas property owners can file their protest online, by mail, or in person through their appraisal district. The Notice of Protest, also known as Form 50 132, is the standard document used to begin the process. Make sure your form is filled out correctly and submitted before the deadline listed on your appraisal notice.
Participate In The Informal Meeting
Most appraisal districts offer an informal conference with an appraiser before a formal hearing is scheduled. This meeting gives you a chance to present your evidence and discuss your concerns directly. Many property owners are able to reach an agreement at this stage without needing to appear before the Appraisal Review Board.
Prepare For The Appraisal Review Board Hearing
If the informal meeting does not resolve your case, it moves to a hearing before the Appraisal Review Board. At this hearing, you will present your evidence and explain why the assessed value should be adjusted. Staying organized and focused on the most relevant details helps strengthen your argument.
Consider Professional Guidance
The protest process can feel complex, especially for first time filers or owners of commercial properties. Many property owners choose to work with professionals who have experience with Texas tax laws and local market trends. This support can help you present a more complete and well researched case.

Consequences Of Missing The Protest Deadline
Missing the Texas property tax protest deadline affects your ability to correct an inaccurate valuation and can have long lasting financial effects. Once the deadline passes, property owners lose the legal right to challenge the number used to calculate their taxes for that year. Below is a closer look at what happens when the protest window closes:
No Opportunity To Dispute The Value
The moment the protest deadline expires, the assessed value on your Notice of Appraised Value becomes final for the entire tax cycle. Even if the figure is based on outdated data or an incorrect comparison, it cannot be adjusted through a protest. Property owners must then wait until the next year to raise any challenges.
Higher Annual Tax Obligations
An inflated assessed value leads to higher taxes. Without the ability to protest, you are required to pay taxes based on that inaccurate figure. This can place strain on household budgets and reduce profitability for commercial properties.
Reduced Flexibility During Market Changes
Real estate markets can change significantly within a year. A protest allows property owners to present evidence that reflects current market conditions. Missing the deadline removes this option and can leave you paying taxes that do not align with the property’s true position in the market.
Increased Operating Stress For Businesses
For commercial property owners, excessive assessments raise operating costs and limit room for reinvestment. These higher expenses can influence pricing decisions, long term planning, and overall financial stability. Filing on time helps prevent these avoidable challenges.
