Texas Property Tax Protest FAQ
Every Texas property owner has the right to protest their property's appraised value each year. The process involves specific deadlines, forms, and hearings that can be confusing for first-time protesters. Below are answers to 25 of the most common questions we receive about Texas property tax protests.
Filing and Deadlines
1. When is the deadline to file a property tax protest in Texas?
The deadline is May 15, 2026, or 30 days after your Notice of Appraised Value is mailed, whichever is later. The exact deadline date is printed on your appraisal notice. If you miss this deadline, you generally cannot protest for that tax year.
For county-specific deadline details, see our Texas property tax protest deadlines guide.
2. How do I file a property tax protest?
File a Notice of Protest (Form 50-132) through one of these methods:
- Online - Most county appraisal districts have online filing portals. You will need your property ID and passcode from your Notice of Appraised Value.
- By mail - Send a completed Form 50-132 to your county appraisal district.
- In person - Visit your appraisal district office.
For step-by-step instructions, see our complete protest filing guide.
3. What forms do I need?
- Form 50-132 (Notice of Protest) - Required to initiate your protest
- Form 50-162 (Appointment of Agent) - Required if someone else will represent you at hearings
- Form 50-283 (Affidavit of Evidence) - Used to submit evidence by affidavit instead of appearing in person
All forms are available on the Texas Comptroller's website and your county appraisal district's website.
4. What grounds can I protest on?
Texas law allows protests on several grounds:
- Market value - Your appraised value exceeds what your property would sell for
- Unequal appraisal - Similar properties in your area are appraised lower than yours
- Errors in property records - Incorrect square footage, lot size, bedroom count, or other details
- Exemption denial - You were denied an exemption you believe you qualify for
- Change of use - Your property's use classification is incorrect
Most residential protests focus on market value and unequal appraisal arguments.
5. Can I protest if my value did not increase this year?
Yes. You can protest even if your appraised value stayed the same or decreased. If comparable sales in your area support a value lower than what the appraisal district assigned, you have grounds to protest regardless of whether the value went up.
Evidence and Preparation
6. What evidence do I need for a successful protest?
The strongest evidence includes:
- Comparable sales - Recent sales of similar homes in your area that sold for less than your appraised value
- Unequal appraisal data - Properties similar to yours that are appraised at lower values
- Property condition documentation - Photos showing deferred maintenance, foundation issues, roof damage, or other problems that reduce your home's value
- Error corrections - Documentation proving your property records contain mistakes (wrong square footage, extra bedrooms, etc.)
- Professional appraisal - A licensed appraisal showing a lower market value
For more on building your case, see our guide on how comparable properties help lower your taxes.
7. Where do I find comparable sales data?
- Your county appraisal district's website (property search tool)
- MLS data (available through real estate agents)
- Recent sales in your neighborhood
- Professional property tax protest firms, which have access to comprehensive sales databases
The best comps are recent sales (within 6-12 months) of homes similar to yours in size, age, condition, and location.
8. Can I use Zillow or Redfin estimates as evidence?
No. Online automated valuations (Zestimates, Redfin estimates) are not accepted by appraisal districts or ARB panels because they are algorithm-generated estimates, not appraisals based on property-specific analysis. Use actual sales data and professional appraisals instead.
The Protest Process
9. What happens after I file a protest?
After filing, the process typically follows this path:
- Informal review - A one-on-one meeting with an appraiser from the appraisal district to discuss your case and negotiate a value
- ARB hearing - If no agreement is reached, your case goes before the Appraisal Review Board, a panel of citizens who review evidence from both sides
- Decision - The ARB issues a binding determination of your property's value
- Appeal (optional) - If you disagree, you can pursue binding arbitration, district court, or SOAH
10. What is the difference between an informal review and an ARB hearing?
The informal review is a negotiation with an appraiser from the appraisal district. It is less formal, typically done by phone or online, and most protests settle at this stage. If you cannot reach agreement, your case advances to the ARB hearing, where a panel of appointed citizens hears evidence from both you and the appraisal district and issues a binding decision.
See our detailed comparison for Harris County informal review vs. ARB hearing.
11. Can protesting my property taxes raise my value?
No. Under Texas law, the Appraisal Review Board cannot increase your property's appraised value as a result of a protest you filed. Your value can only stay the same or go down. There is zero risk to filing a protest.
12. Can I protest my property taxes every year?
Yes. Texas law allows annual protests regardless of whether you protested the previous year or received a reduction. Annual protests are recommended because property values change each year and each successful reduction lowers your baseline for the 10% homestead cap.
13. How much can I save by protesting?
Savings depend on your home's value, local tax rates, and how much the appraised value exceeds market value. A typical 10% reduction on a $400,000 home at a 2% combined tax rate saves approximately $800 per year. Those savings compound through the 10% homestead cap, making each successful protest more valuable over time.
Your Rights as a Protester
14. What rights do I have during the protest process?
Texas property tax protesters have several rights under the Tax Code:
- Right to protest - Every property owner can protest annually
- No risk of increase - Your value cannot go up as a result of filing
- Right to representation - You can appoint an agent to act on your behalf
- Right to evidence - The appraisal district must provide their evidence at least 14 days before your ARB hearing
- Right to postpone - You can reschedule your hearing (typically once, sometimes twice)
- Right to a remote hearing - Most counties offer phone or video hearing options
- Right to appeal - You can appeal an ARB decision through binding arbitration, district court, or SOAH
15. What is a taxpayer liaison officer?
Every Texas appraisal district is required by law to have a taxpayer liaison officer who assists property owners with the protest process. This person can:
- Answer questions about how to file a protest
- Explain the hearing process and your rights
- Help resolve procedural issues
- Provide information about exemptions
Contact your county appraisal district to reach their taxpayer liaison officer if you need help navigating the process.
16. Can I request an interpreter for my hearing?
Yes. Texas law requires appraisal districts to provide language interpreter services and sign language interpreter services at ARB hearings upon request. Contact your appraisal district before your hearing date to arrange interpreter services. There is no cost to you.
17. Can someone else attend my hearing for me?
Yes. You can appoint a representative - such as a property tax consultant, attorney, or any other person - to attend and present your case on your behalf by filing Form 50-162 (Appointment of Agent). Many homeowners use property tax protest firms so they do not need to take time off work.
After the Hearing
18. What happens if my protest is denied?
If the ARB does not lower your value, you have additional options:
- Binding arbitration - Available for properties with appraised values under $5 million. Filing fee ranges from $500 to $1,550 depending on value. A neutral arbitrator reviews the case and issues a binding decision.
- District court appeal - You can file a lawsuit in district court within 60 days of the ARB's final order.
- State Office of Administrative Hearings (SOAH) - For properties appraised over $1 million, you can appeal to SOAH, which uses an administrative law judge. This is generally faster and less expensive than district court.
19. If I win, when does the reduction take effect?
The reduced value applies to your tax bill for the current tax year. If you pay property taxes through escrow, your mortgage company will adjust your monthly payment during the next escrow analysis (typically within 6-18 months). If you pay directly, the lower value is reflected on your tax bill due in January.
20. Does a reduction carry forward to future years?
Yes and no. The ARB's decision applies only to the current tax year. However, a lower value creates a lower baseline for the 10% homestead cap, which limits future annual increases. This compounding effect means a successful protest today can save you money for years to come.
Hiring Help
21. Is it worth hiring a property tax protest company?
For most homeowners, yes. Professional firms have access to comprehensive comparable sales databases, experience presenting at ARB hearings, and work on contingency - you only pay if they reduce your value. The reduction typically carries forward for multiple years while the fee is based on first-year savings only.
For a detailed comparison, see our guide on the best property tax protest companies in Texas.
22. How do property tax protest companies charge?
Most reputable firms charge a contingency fee between 25% and 50% of your first-year tax savings. You pay nothing upfront, and if the company fails to reduce your value, you owe nothing. Avoid any company that requires payment before delivering results.
23. Can I protest on my own?
Absolutely. Texas law is designed to allow homeowners to file and present their own protests without professional help. If you have time to research comparable sales, prepare your evidence, and attend the hearing, DIY protesting is a viable option.
Exemptions and Related Topics
24. Should I file for a homestead exemption before protesting?
Yes. The homestead exemption removes $100,000 from your taxable value for school district taxes and activates the 10% annual cap on assessed value increases. File your homestead exemption first, then protest the appraised value for maximum savings.
