Houston Property Tax Appeals Guide
Step-by-step guide to protesting your Houston property tax appraisal and saving hundreds annually.
Why Every Houston Homeowner Should Protest
Texas has no state income tax, which means local governments rely heavily on property taxes. The Houston metro's effective property tax rate of **1.9%** is among the highest in the nation, and appraisal districts aggressively increase assessed values to keep pace with rising revenue needs.
Here's the critical fact: **Harris County homeowners who protest their appraisal win a reduction approximately 60% of the time**. Yet only about 6% of homeowners actually file a protest each year.
On a home appraised at $350,000, even a modest 10% reduction saves approximately **$665/year** in property taxes.
The Houston Metro Tax Landscape
| County | Effective Rate | Avg Appraisal Increase (2025) | Protest Success Rate |
|--------|---------------|-------------------------------|---------------------|

| Fort Bend | 2.05% | 7.5% | ~55% |
| Montgomery | 1.85% | 9.1% | ~58% |
| Brazoria | 1.88% | 6.8% | ~52% |
| Galveston | 1.92% | 7.2% | ~50% |
Step-by-Step Protest Process
Step 1: Review Your Notice of Appraised Value
Harris County Appraisal District (HCAD) mails appraisal notices in April. Your notice shows:
- **Market value**: What HCAD thinks your property would sell for
- **Appraised value**: The value used for tax calculation (subject to homestead cap)
- **Assessed value**: Appraised value minus exemptions
Step 2: File Your Protest (Deadline: May 15 or 30 days after notice)
File online through HCAD's iFile system or by mail. You don't need a reason — just check "Value is over market value" and/or "Value is unequal compared to other properties."
Step 3: Gather Evidence
Strong protest evidence includes:
- **Comparable sales**: 3–5 recent sales of similar homes within 1 mile, sold for less than your appraised value
- **Equity comparables**: Similar properties appraised lower than yours by HCAD
- **Condition issues**: Photos of deferred maintenance, foundation issues, or needed repairs
- **Professional appraisal**: A licensed appraisal ($300–$500) carries significant weight
Step 4: Attend Your Hearing
You can attend in person or by phone. Most informal hearings last 10–15 minutes. Present your evidence calmly and let the numbers speak.
Step 5: Escalate If Needed
If the informal hearing doesn't produce a satisfactory result, you can escalate to:
- Appraisal Review Board (ARB) formal hearing
- Binding arbitration ($500 filing fee, refunded if you win)
- District court (for high-value properties)

DIY vs. Hiring a Tax Protest Firm
| Approach | Cost | Avg Reduction | Effort |
|----------|------|---------------|--------|
| DIY protest | Free | $400–$600 | 3–5 hours research + hearing |
| Tax protest firm | 33–40% of savings | $500–$800 | Minimal — they handle everything |
| Licensed appraiser | $300–$500 flat fee | $600–$1,000+ | 1 hour for appraisal appointment |
Tax protest firms like O'Connor, Gill & Associates, or Bezerra & Associates handle the entire process on contingency — you only pay if they save you money.

FAQ
When is the deadline to protest my Houston property tax?
The general deadline is May 15 or 30 days after your appraisal notice is mailed, whichever is later. For Harris County, notices typically mail in mid-April, so the effective deadline is usually mid-to-late May.
Can I protest every year?
Yes. There is no limit on how often you can protest. Many Houston homeowners protest annually and achieve reductions most years. The process is free to file.
What if I just bought my house — can I still protest?
Absolutely. Your purchase price establishes a clear market value that HCAD must consider. If HCAD appraised your home above your recent purchase price, you have strong evidence for a reduction.
