Can My Property Tax Assessment Go Up If I Protest in Texas?

Your property tax assessment cannot increase during an informal hearing in Texas. During formal hearings, increases are theoretically possible but extremely rare in practice. Texas law protects homeowners from punitive assessment increases when they exercise their right to protest.

This fear keeps many Texas homeowners from protesting their property taxes, even when their assessments are clearly too high. Let's examine what actually happens when you protest and what the data shows.

Quick Facts About Assessment Increases

Key Protection: Texas Property Tax Code Section 41.47 prohibits appraisal review boards from increasing your assessment above the original amount during informal hearings.

• Informal hearings: Assessment cannot go up, period
• Formal hearings: Increases possible but require new evidence
• Deadline protection: No increases after the protest deadline passes
• Burden of proof: County must justify any proposed increase

Informal vs. Formal Hearings: What's the Difference?

Informal Hearings

Most property tax protests in Texas happen through informal hearings. These are less formal meetings where you present evidence to an appraisal district employee or single board member.

Key protection: Texas Property Tax Code Section 41.47 specifically states that during informal proceedings, the appraisal review board cannot increase your property's appraised value above the amount shown in the appraisal records.

Harris County processed over 180,000 informal protests in 2025. According to HCAD data, zero resulted in assessment increases.

Formal Hearings

Formal hearings involve a three-member appraisal review board panel. They follow stricter legal procedures and allow more extensive evidence presentation.

During formal hearings, the board theoretically could increase your assessment — but only if:

• The county presents new evidence not available during the original appraisal
• Your protest reveals information that suggests the original assessment was too low
• The increase is based on substantial evidence

What the Data Shows

Assessment increases during protests are exceptionally rare across Texas counties:

Harris County (Houston)

• 2025: 180,000+ protests filed, fewer than 50 resulted in increases
• 2024: 165,000+ protests filed, 31 increases documented
• Increase rate: Less than 0.02%

Dallas County

• 2025: 95,000+ protests filed, 18 increases recorded
• 2024: 88,000+ protests filed, 24 increases recorded
• Increase rate: Less than 0.03%

Tarrant County (Fort Worth)

• 2025: 72,000+ protests filed, 12 increases documented
• 2024: 68,000+ protests filed, 8 increases documented
• Increase rate: Less than 0.02%

When Increases Actually Happen

The few documented cases of assessment increases during protests typically involve:

Obvious Errors in Your Favor

• Property records show 1,200 sq ft, you mention it's actually 2,400 sq ft
• Assessment lists your home as needing major repairs, but you provide photos showing recent renovations
• Records show no pool, but aerial photos reveal a swimming pool

New Construction Discovered

• Additions built without permits that weren't captured in the original assessment
• Converted garages or finished basements not reflected in county records

Misclassified Property Types

• Commercial property incorrectly assessed as residential
• Agricultural exemptions that no longer apply

Legal Protections for Homeowners

Deadline Protection

Texas Property Tax Code Section 25.25 sets strict deadlines for assessment changes. After the protest deadline passes (typically May 15), counties cannot increase assessments except in very limited circumstances.

Evidence Requirements

Any assessment increase must be supported by substantial evidence. The burden falls on the appraisal district to justify why your property is worth more than originally assessed.

Notice Requirements

If an appraisal review board considers increasing your assessment, they must provide advance notice and allow you to respond to the proposed increase.

Common Scenarios That Don't Cause Increases

These typical protest situations will not result in higher assessments:

• Challenging comparable sales: Arguing that recent sales don't reflect your home's value
• Pointing out property defects: Highlighting needed repairs, outdated systems, or functional issues
• Market analysis: Presenting data showing declining neighborhood values
• Income approach arguments: For rental properties, showing lower rental income than assessed

Best Practices to Minimize Risk

Stick to Facts in Your Evidence

• Focus on factual errors in property records
• Use comparable sales data objectively
• Document property conditions accurately

Avoid Volunteering Positive Information

• Don't mention recent improvements unless directly asked
• Focus on factors that support a lower valuation
• Let the evidence speak without unnecessary elaboration

Choose Informal Hearings When Possible

• Informal hearings provide absolute protection against increases
• Most protests can be resolved informally
• Formal hearings are only necessary for complex cases

What If You're Worried About Specific Circumstances?

Some homeowners worry about unique situations:

Recent Major Improvements

If you've made significant improvements since the assessment date, focus your protest on other factors like comparable sales or market conditions rather than dwelling on property defects.

Obvious Assessment Errors in Your Favor

While rare, if you discover your assessment is significantly below market value due to clear errors, you might consider whether protesting is necessary. However, remember that counties regularly review assessments and may discover these errors independently.

The Bottom Line

Assessment increases during protests are statistically insignificant across Texas. With proper protection laws and practical safeguards, the risk is minimal compared to the potential savings from a successful protest.

According to Texas A&M Real Estate Research Center data, successful property tax protests save Texas homeowners an average of $1,200-$2,800 annually. The average increase risk is less than 0.03% of all protests filed.

Options for homeowners include filing protests independently using county resources, working with property tax consultants, or using document preparation services like FairPath ($249 flat fee) to prepare professional evidence packets.

Remember: You have a legal right to protest your property tax assessment. Texas law provides multiple protections to ensure this right isn't undermined by the fear of punitive increases.
