How to Protest Your Property Taxes in Harris County

Every year, the Harris County Appraisal District (HCAD) sets the appraised value of your home. If you believe your property is over-assessed, you have the legal right to protest — and support a different value with evidence. Any tax savings depend on the resulting taxable value and tax rates.

Who Can Protest?

Any property owner in Harris County can file a protest. You don't need a lawyer or a tax agent to file. Compare the official property record with relevant evidence and explain the value you are requesting; a reduction is not guaranteed.

When Is the Deadline?

The protest deadline is May 15 each year, or 30 days after your notice of appraised value is mailed — whichever is later. HCAD typically mails notices in mid-April. Late protests are generally not accepted, so mark your calendar.

You can check if your notice has been mailed by visiting search.hcad.org and looking at the "Notice Date" field.

Step 1: Check Your Assessment

Start by looking up your property on Harris Value or on HCAD's website. Review your appraised value, square footage, bedroom/bathroom count, and other details. Errors in these fields are common — incorrect square footage alone can inflate your assessment by thousands of dollars.

Step 2: Gather Evidence

There are two main approaches to building your case:

  • Unequal appraisal (equity): Show that similar properties in your neighborhood are appraised at lower values per square foot. This is the most common and effective strategy — you're using HCAD's own data to prove inconsistency.
  • Market value: Show that recent sales of comparable homes indicate your property is worth less than HCAD's appraised value. This requires actual sales records.

Harris Value generates both types of evidence automatically — enter your address to see your comparable properties and potential savings.

Step 3: File Your Protest

The easiest way to file is online through HCAD's iFile system. You can also file by mail using Form 50-132 or in person at the HCAD office at 13013 Northwest Freeway, Houston.

When filing, check the box for "Value is over market value" and/or "Value is unequal compared with other properties." Enter your opinion of value — this is required to receive a settlement offer through iSettle.

Step 4: The Informal Settlement

After filing, HCAD's iSettle system may generate a settlement offer before your formal hearing. You can also request an informal phone conference with an HCAD appraiser. An accepted settlement can resolve your protest without a formal ARB hearing.

Tip: If the informal offer is close to what you want, consider accepting it. The formal hearing isn't guaranteed to produce a better result.

Step 5: Attend Your Hearing

If the informal stage doesn't resolve your case, you'll receive a hearing date with the Appraisal Review Board (ARB). Harris County offers three participation options: in person at the HCAD office, by telephone, or by video conference. Bring your evidence: a printed list of comparable properties with their assessed values and any recent sales data.

Tips for Success

  • Focus on 3-5 strong comparable properties, not 20 weak ones
  • Highlight the assessed value per square foot — it's the metric that matters most
  • Be polite and factual; the ARB responds to data, not emotions
  • If you're offered a settlement, do the math — even a partial reduction saves you money
  • You can protest every year; there's no penalty for filing

Sources and evidence for Harris County

Prepared by Harris Value. Filing resources checked September 4, 2026.

Start with the Harris County Appraisal District property record and your current notice. Our property pages organize imported public assessment records and available comparable evidence. Check the tax year and data dates shown on each page: a prior-year record is useful history, but does not establish the value on a new notice.

Comparable homes are candidates for review. Verify their size, age, condition, location, and sale details before using them. Value per square foot helps screen candidates; it does not account for every difference. Estimated savings depend on the final assessment, exemptions, assessment limits, and applicable tax rates.

Texas filing and valuation checks

For 2026, the ordinary May 15 filing date has passed. A notice mailed later can have a later deadline. Confirm the date on your notice and the HCAD filing instructions. Review Texas Comptroller protest guidance for procedures and owner rights.

Separate a market-value argument from unequal appraisal, and compare the same tax year. A homestead cap or exemption can make taxable value differ from market value; lowering market value may not change the bill immediately. Texas sales coverage is incomplete because sale prices are not universally disclosed.

Check the source before filing

Harris Value is an independent research tool. Verify the current procedure with Harris County Appraisal District, save a copy of your evidence, and retain your filing confirmation. The appraisal authority or review board decides the outcome.
