Harris County Property Tax Protest, Texas
Watch: How to protest your property taxes in Harris County
Harris County is the third-most populous county in the United States with over 5 million residents, and the county seat is Houston, the largest city in Texas with over 2.4 million people. Major population centers include Houston, Pasadena, Baytown, Pearland, League City, and The Woodlands. Property tax protests are especially critical in Harris County due to its significantly higher-than-average tax burden, the county's effective property tax rate of 1.46% is well above the national average of 0.89%, and the median annual property tax bill of $4,416 exceeds the national median of $2,400 by $2,016. With the median home value at approximately $301,700 and one of the most complex property tax structures in Texas, Harris County homeowners face substantial tax obligations that make protesting essential for ensuring fair assessments.

How Harris County Assesses Property
Assessed by: Harris Central Appraisal District (HCAD)
Assessment cycle: annual
Notices typically mailed: late March to early April
In Texas, properties are assessed at 100% of their market value, meaning there is no reduction between market value and assessed value. For Harris County homeowners, if your home's market value is $301,700 (the county median), your assessed value would be $301,700 at the 100% assessment ratio. At Harris County's effective tax rate of 1.46%, this would result in approximately $4,405 in annual property taxes before any exemptions are applied. However, homestead exemptions can significantly reduce your taxable value and lower your actual tax bill.
The Protest Process
Appeals are heard by the Appraisal Review Board (ARB). ARB hearings are conducted informally and typically last 15 minutes. You will present your evidence to a panel of ARB members, who will ask clarifying questions. The appraisal district will also present their evidence. The board will then determine if your property was over-appraised and issue a written decision.
Step 1: Review your Notice of Appraised Value when it arrives (typically late March or early April). Check the protest deadline printed on the notice and verify all property details such as square footage, bedrooms, bathrooms, and exemptions are accurate.
Step 2: Research comparable properties in your neighborhood using HCAD's property search tool at hcad.org. Look for similar homes that sold recently for less than your assessed value, or comparable properties assessed at lower values to build an unequal appraisal argument under Texas Tax Code Section 41.43.
Step 3: File your protest before the deadline using HCAD's iFile online system (recommended), by mail, or in person. State your opinion of value and the grounds for your protest (market value too high, unequal appraisal, or both). You have 5 calendar days after filing to upload supporting evidence.
Step 4: Wait for an iSettle offer from HCAD. The appraisal district will review your evidence and may send you a settlement offer electronically through the iSettle system. Review the offer carefully and either accept it to resolve your protest immediately, or reject it to proceed to a formal ARB hearing.
Step 5: If you reject the settlement or don't receive an iSettle offer, attend your scheduled Appraisal Review Board (ARB) hearing. Present your evidence including comparable sales, photos, repair estimates, and your equity analysis. Most hearings are allotted 15 minutes, so prepare a clear, organized presentation.
Step 6: Receive the ARB's written decision via certified mail. If you disagree with the ARB decision, you have three post-ARB appeal options: (1) binding arbitration for properties valued at $1 million or less or residence homesteads, (2) State Office of Administrative Hearings (SOAH) for properties over $1 million, or (3) district court appeal within 60 days of receiving the written order.
