With 2025 property valuation notices set to arrive in Harris County mailboxes next month, homeowners are asking important questions about the assessment process. This guide addresses the most common questions we receive from Harris County homeowners preparing for protest season.
Understanding Your Property Valuation
What exactly is a property valuation notice?
A property valuation notice (officially called a "Notice of Appraised Value") is an official document from the Harris Central Appraisal District (HCAD) informing you of your property's assessed value.
The notice includes:
- Your property's market and appraised value
- The deadline to file a protest
- Instructions for filing a protest
How does HCAD determine my property's value?
HCAD uses a mass appraisal system that considers:
- Recent sales of comparable properties in your area
- Your property's physical characteristics (square footage, bedrooms, etc.)
- Your property's age and condition (based on available data)
- Land values in your neighborhood
For most residential properties, HCAD primarily relies on the "market approach," comparing your property to similar properties that have recently sold.
What's the difference between market value and appraised value?
- Market value is what your property would likely sell for in an open market between a willing buyer and seller.
- Appraised value is HCAD's assessment of your property's value for tax purposes.
Ideally, these values should be similar. However, exemptions (like the Homestead or Over-65 exemptions) can create differences between market value and appraised value for tax purposes.
Why did my property value increase when I haven't made any improvements?
Property values can increase due to several factors unrelated to home improvements:
- Rising market values in your neighborhood
- Increased demand for properties in your location
- New amenities or developments nearby
- General market appreciation
- Correction of previous undervaluation
Property Tax Protests
What is a property tax protest?
A property tax protest is a challenge to HCAD's assessment of your property's value. As a property owner, you have the legal right to protest if you believe your property has been overvalued or valued unequally compared to similar properties.
What are the deadlines for filing a protest in 2025?
For most Harris County homeowners, the deadline to file a protest is May 15, 2025. However, the technical deadline is the later of:
- May 15, 2025, or
- 30 days after the date your Notice of Appraised Value was delivered
This means if you receive your notice after April 15, your deadline may extend beyond May 15.
What are the valid reasons to protest my property valuation?
Texas law allows you to protest your property valuation on several grounds:
- Market value: Your property is appraised at a higher value than it would sell for
- Unequal appraisal: Your property is appraised unequally compared to similar properties
- Exemption denial: You were denied an exemption you believe you qualify for
- Failure to provide notice: HCAD failed to send required notices
- Other matters: Including incorrect property description or ownership
How do I file a protest?
Harris County homeowners can file a protest in three ways:
- Online (recommended):
- Visit HCAD's protest website
- Enter your property account number from your notice
- Complete the electronic protest form
- Receive immediate confirmation
- By mail:
- Complete the protest form attached to your notice
- Mail to: Harris County Appraisal District, P.O. Box 922012, Houston, TX 77292-2012
- Must be postmarked by the deadline
- In person:
- Visit HCAD's office at 13013 Northwest Freeway, Houston, TX 77040
- Submit your completed protest form
- Request a receipt confirming your filing
What evidence should I gather for my protest?
Effective evidence for a property tax protest includes:
For market value protests:
- Recent sales of comparable properties (within 6-12 months)
- Photos documenting condition issues with your property (as of January 1)
- Repair estimates for significant problems
- Recent fee appraisal (if available)
For equity protests:
- Assessment values of similar properties in your area
- Comparison of per-square-foot values
- Evidence of similar properties with lower assessments
What happens after I file a protest?
After filing your protest, the process typically follows these steps:
- Acknowledgment: You'll receive confirmation that your protest was received
- Informal Hearing Assignment: HCAD will schedule an informal hearing for you with an appraiser
- Evidence Exchange: You'll have the opportunity to submit evidence before your hearing
- Informal Hearing: Meet with an HCAD appraiser to discuss your valuation
- Potential Settlement: Many cases resolve at the informal stage
- Formal Hearing (if needed): Present your case to the Appraisal Review Board (ARB)
- Final Determination: Receive the ARB's decision on your protest
What's the difference between informal and formal hearings?
Informal Hearing:
- One-on-one meeting with an HCAD appraiser
- More conversational and flexible
- Opportunity to negotiate and reach settlement
- Typically takes 15-30 minutes
- Resolves approximately 70% of protests
Formal Hearing:
- Presentation before a panel of ARB members (usually 3)
- More structured with formal procedures
- Time-limited presentations (15 minutes for both you and the District)
- Final decision determined by ARB
- Can only be appealed through binding arbitration or litigation
What are my chances of success with a protest?
Success rates vary based on several factors:
- Evidence quality: Well-prepared cases with strong evidence have higher success rates
- Who handles the protest: Self-represented properties are typically more successful than those represented by agents.

Harris County homeowners may qualify for several exemptions:
- Homestead Exemption: For your primary residence, providing:
