Harris County Property Tax Protest
A Harris County property tax protest is how you challenge the value the appraisal district put on your home. It is free to file yourself, the window is short, and a well-prepared protest often lowers your value, which lowers the taxes every taxing unit charges. This guide walks the deadline, how to file, what evidence works, and what happens at the hearing.
Protest basics
- Deadline: May 15, or 30 days after your notice was mailed, whichever is later.
- File with the Harris Central Appraisal District (HCAD), online or by mail.
- Two grounds: value is over market or the appraisal is unequal versus similar homes.
- Filing yourself is free. Bring evidence to the informal review and the ARB hearing.
Know your deadline
The protest deadline is May 15, or 30 days after the date HCAD mailed your notice of appraised value, whichever is later. The date printed on your own notice is the one that governs, so open district mail in the spring and note the date. Missing the window usually means waiting a full year.
How to file
The fastest route is HCAD iFile online, which lets you submit your protest and, in many cases, receive an iSettle offer, a proposed value you can accept or decline without a hearing. You can also file the state Notice of Protest, Form 50-132, by mail or in person. When you file, state both common grounds unless one clearly does not apply: that the market value is too high, and that your home is appraised unequally compared with similar properties.
Build your evidence
A protest is stronger with evidence than with opinion. Useful support includes:
- Recent sale prices of comparable homes near you, ideally close in size, age, and condition.
- Unequal-appraisal comparisons showing similar homes appraised for less.
- Photos of anything that lowers value, such as foundation movement, roof damage, or dated interiors.
- Repair estimates from a contractor for major issues.
- A closing statement if you bought the home recently for less than the appraised value.
You can also request the evidence HCAD plans to use, so you can see the comparable sales behind your value before you meet.
The informal review and the ARB hearing
Many protests settle before a formal hearing. In an informal review, you present your evidence to an appraiser who can offer a reduction on the spot. If you cannot agree, your protest goes to the Appraisal Review Board, an independent panel that hears both sides and sets a value. Hearings can be in person, by phone, or by written affidavit, and HCAD holds some Saturday hearings in June and July. Present your strongest comparables first and keep it factual.
If you still disagree
After the ARB issues its order, Texas gives owners further options depending on the property and value, including binding arbitration, an appeal to district court, or, for some properties, the State Office of Administrative Hearings. Most homeowners settle at the informal or ARB stage, but the later remedies exist if the numbers justify it.

Frequently asked questions
What is the deadline to protest in Harris County?
The deadline is May 15, or 30 days after the date the appraisal district mailed your notice of appraised value, whichever is later. The date on your notice is what counts, so read it each spring.
Does it cost anything to protest your own property taxes?
No. Filing a protest yourself with the Harris Central Appraisal District is free. You only pay if you hire a firm or agent to protest for you, usually a share of the tax savings.
Will protesting lower my taxes in future years?
It can. A reduction applies to the current year's value, and because next year's value often starts from this year's, a lower number can carry forward and reduce increases later.
