Common Mistakes Homeowners Make When Protesting Property Taxes
August 13, 2025
Protesting your property taxes can save you hundreds or even thousands of dollars, but it’s a process that requires preparation, precision, and a clear understanding of local regulations. Texas homeowners, in particular, face some of the highest property tax rates in the nation, making it even more critical to approach the protest process carefully. However, many homeowners fall into common traps that can derail their efforts or limit the success of their appeal. Here are the top property tax protest mistakes to avoid and practical tips to ensure your protest is as effective as possible.
Failing to Meet Deadlines
One of the most critical property tax protest mistakes homeowners make is missing the deadline to file their protest. In Texas, you must submit your protest by May 15th or within 30 days of receiving your appraisal notice, whichever comes later. Missing this window means you lose the chance to challenge your property’s valuation for the year.
How to Avoid This Mistake:
- Mark the deadline on your calendar as soon as you receive your appraisal notice.
- File your protest as early as possible to allow ample time for gathering evidence.
- Use the Texas Comptroller’s website or your local appraisal district’s online portal to stay updated on deadlines and submission methods.
Providing Insufficient Evidence
Another common pitfall is not providing enough evidence to support your case. Simply stating that your property taxes are too high isn’t enough to convince the Appraisal Review Board (ARB). You need compelling, data-backed evidence that demonstrates your property’s value is lower than what’s listed in the appraisal.
How to Avoid This Mistake:
- Collect recent sales data for comparable properties in your neighborhood.
- Take clear photos of your property’s condition, especially if there are issues that might reduce its value (e.g., foundation problems or outdated features).
- Obtain professional appraisals or market analyses if possible.

Ignoring Your Appraisal Notice
Some homeowners make the mistake of assuming their appraisal notice is accurate or not worth reviewing. Others may disregard it entirely due to a lack of understanding about how property taxes are calculated. Ignoring your appraisal notice can lead to overpaying on property taxes for years.
How to Avoid This Mistake:
- Review your appraisal notice thoroughly each year.
- Look for discrepancies, such as inaccurate square footage or an overestimation of market value.
- Take action immediately if you notice any errors or feel the valuation is too high.
Overvaluing DIY Efforts
While it’s possible to protest your property taxes without professional help, many homeowners underestimate the complexity of the process. From gathering evidence to navigating the hearing, a DIY approach can lead to avoidable errors or weaker presentations.
How to Avoid This Mistake:
- Engage a licensed tax professional with experience in Texas property tax protests.
- Professionals often have access to market data and appraisal district trends, giving them an advantage in preparing your case.
- If you decide to go it alone, research the process thoroughly and prepare beforehand.
Relying on Emotional Arguments
Many homeowners fall into the trap of making emotional appeals to the ARB, such as discussing financial hardship or personal circumstances. While understandable, these arguments are unlikely to sway the board. Their focus is strictly on whether your property’s assessed value is accurate.
How to Avoid This Mistake:
- Stick to factual, evidence-based arguments.
- Present your case using objective data, such as comparable sales or property condition reports.
- Avoid discussing unrelated issues, such as rising property tax rates or dissatisfaction with local services.
Not Preparing for the ARB Hearing
The Appraisal Review Board hearing allows you to present your evidence and make your case, but many homeowners show up unprepared or fail to attend altogether. This mistake significantly reduces the chances of a successful protest.
How to Avoid This Mistake:
- Organize your evidence in a clear, logical manner before the hearing.
- Practice your presentation to ensure you can explain your points succinctly and confidently.
- Designate a representative or request a written affidavit hearing if you cannot attend the hearing.

Overlooking Homestead Exemptions
While not directly related to the protest process, failing to apply for available homestead exemptions is a common oversight that can increase your overall tax burden. Exemptions can reduce the taxable value of your home, making it less likely that your property is overvalued.
How to Avoid This Mistake:
- Apply for a homestead exemption if you haven’t already done so. This is a one-time application for most homeowners.
- Check for other exemptions, such as those for seniors, veterans, or individuals with disabilities.
- Review your tax bill each year to ensure exemptions have been applied.
Not Following Up After the Protest
Even if your protest is successful, your work might not be over. Some homeowners make the mistake of not reviewing their final valuation or tax bill after the protest. Errors can still occur, and it’s essential to ensure the changes are applied correctly.
How to Avoid This Mistake:
- Review your final valuation notice to confirm it reflects the ARB’s decision.
- Check your tax bill to ensure the corrected valuation was used to calculate your taxes.
- Stay vigilant each year to avoid falling back into overpayment.
Avoiding Tax Protest Errors: Final Tips for Texas Homeowners
Avoiding these property tax protest mistakes requires diligence, organization, and sometimes professional assistance. Here are a few final tips to help you navigate the process effectively:
- Stay Educated: Understand the protest process, deadlines, and requirements specific to your appraisal district.
- Be Proactive: Don’t wait until the last minute to file your protest or gather evidence.
- Engage Experts: Licensed tax professionals can simplify the process and improve your chances of success.
Protesting your property taxes doesn’t have to be overwhelming. By avoiding these common pitfalls and approaching the process strategically, you can reduce your tax burden and ensure a fair valuation for your home.
