3 Reasons to Appeal Your Assessment

If you’re a Houston homeowner, appealing your property tax assessment could save you thousands of dollars in 2025. Here’s why you should consider taking action:

1. Your Property May Be Overvalued

Harris County property valuations often exceed market value, especially in rapidly changing neighborhoods. For example, if your home was assessed at $400,000 but comparable homes in your area are selling for $350,000, you’re likely overpaying. Appealing ensures your valuation aligns with real market conditions.

2. Errors in Your Assessment Are Common

Mistakes happen. Your assessment might include incorrect square footage, outdated improvements, or even properties that aren’t yours. Review your notice carefully—if you spot errors, appealing is your best chance to correct them and lower your tax bill.

3. 2025 Could Bring Higher Taxes

With rising property values and potential tax rate changes, 2025 assessments may hit harder. Proactively appealing now can lock in a fair valuation, protecting you from future spikes.

Step-by-Step Appeal Process

If you believe your 2025 property tax assessment is too high, you can appeal it to potentially lower your tax bill. Here’s a clear, step-by-step process to guide you:

1. Review Your Assessment Notice

• Houston homeowners receive their property tax assessment notices in April 2025.
• Check for errors in property details (e.g., square footage, number of bedrooms) and compare your valuation to similar homes in your area.

2. Gather Evidence

• Collect proof to support your case, such as recent sales of comparable homes, photos of property damage, or appraisals.
• Use tools like TaxLasso to quickly access professional-level market data and insights in just 5 minutes, saving hours of research.

3. File Your Protest

• Submit your protest online, by mail, or in person by the May 15, 2025, deadline (or 30 days after receiving your notice).
• Include all supporting documents and clearly state why your property is overvalued.

4. Prepare for the Hearing

• If your protest isn’t resolved informally, you’ll attend a hearing with the Harris County Appraisal Review Board (ARB).
• Present your evidence confidently, focusing on factual comparisons and errors in the assessment.

5. Consider Professional Help

• While DIY appeals are possible, they can be time-consuming and overwhelming. Legal firms charge thousands of dollars for similar services.
• TaxLasso offers a superior alternative: it’s affordable, takes just 5 minutes, and provides expert-level insights without the high cost of legal firms.

Critical Evidence to Collect

To successfully appeal your property tax assessment in Houston, gathering critical evidence is essential. This evidence will help you prove your property is overvalued, potentially saving you thousands of dollars in 2025. Start collecting the following key documents and data:

1. Current Property Assessment Details

• Obtain your 2025 property tax assessment notice from the Harris County Appraisal District (HCAD).
• Verify the assessed value, square footage, and property classification for accuracy.

2. Comparable Sales (Comps)

• Collect data on recent sales of similar properties in your neighborhood (within the last 6-12 months).
• Focus on homes with similar size, age, and condition. For example, if your 2,000 sq. ft. home is valued at $400,000, but nearby comps sold for $350,000, this is strong evidence of overvaluation.

3. Photos and Repair Estimates

• Document any property issues (e.g., foundation cracks, roof damage) with photos.
• Include repair estimates to show how these issues reduce your home’s market value.

4. Independent Appraisal

• Hire a licensed appraiser to provide a professional valuation of your property. While this costs $300-$500, it can be a powerful tool in your appeal.

5. Market Trends and Neighborhood Data

• Gather data on declining market trends or neighborhood-specific issues (e.g., flooding, high crime rates) that could lower your property’s value.

How to Calculate Fair Market Value

Calculating the fair market value of your property is the first step to appealing your property tax assessment. Fair market value is the price your home would sell for under normal market conditions, and it’s the basis for your property tax bill. Here’s how to calculate it effectively:

1. Use Recent Comparable Sales (Comps)

• Research recent sales of similar properties in your Houston neighborhood. Focus on homes with the same size, age, and features as yours.
• Use resources like the Harris County Appraisal District (HCAD) website or real estate platforms like Zillow or Realtor.com.
• Example: If a 2,000 sq. ft. home in your area sold for $350,000 in early 2025, this is a strong comp for your property.

2. Adjust for Differences

• If your home has unique features (e.g., a pool, updated kitchen, or larger lot), adjust the comps accordingly.
• Example: A pool might add $20,000 to your home’s value compared to a comp without one.

3. Consider Market Trends

• Houston’s real estate market fluctuates. Check 2025 trends to see if prices are rising or falling in your area.
• Example: If home values in your ZIP code increased by 5% in 2025, factor this into your calculation.

4. Get a Professional Opinion

• If DIY research feels overwhelming, TaxLasso can calculate your fair market value in just 5 minutes. Their platform uses professional-level insights to save you hours of work.

Why TaxLasso is the Best Option

• DIY Alternative: TaxLasso provides expert-level accuracy without the time commitment.
• Legal Firm Alternative: Save thousands compared to hiring a firm while maintaining full control over your appeal.

By accurately calculating your fair market value, you’ll have the evidence needed to challenge your property tax assessment and potentially lower your bill.

Understanding State Property Tax Laws in Texas

Texas has some of the highest property taxes in the U.S., and Houston homeowners face unique challenges due to rising valuations. The state mandates that property taxes are based on the appraised value of your home, determined by your local appraisal district. However, Texas law also provides homeowners with the right to protest their property tax assessments if they believe the valuation is inaccurate.

Key Facts for Houston Homeowners:

• Deadlines Matter: In Texas, the deadline to file a property tax protest is typically May 15 or 30 days after you receive your appraisal notice, whichever is later. For 2025, mark your calendar early to avoid missing this critical window.
• Evidence is Crucial: To successfully appeal, you’ll need evidence like recent sales of comparable homes, photos of property damage, or an independent appraisal.
• State Caps: Texas caps annual property tax increases for homesteads at 10% under state law, but this doesn’t apply to new construction or non-homestead properties.

Why Protest?

• Save Money: A successful protest can lower your tax bill by thousands of dollars annually.
• Future Benefits: Lowering your assessed value now can prevent higher taxes in future years.

County-Specific Requirements

Houston homeowners must follow county-specific requirements when appealing their 2025 property tax assessment, as Harris County has unique deadlines, forms, and evidence submission rules. Start by checking the Harris County Appraisal District (HCAD) website for the exact appeal deadline, typically in May, and download the required protest form. Gather evidence like recent comparable sales, photos of property damage, or repair estimates to strengthen your case. DIY appeals can be time-consuming, and hiring a legal firm may cost thousands. TaxLasso simplifies this process with a 5-minute submission, saving you hours of work while providing professional-quality insights. It ensures compliance with county-specific rules and maximizes your chances of reducing your tax bill, all while keeping you in full control of the process.

5 Common Mistakes to Avoid

Appealing your property tax assessment can save you thousands of dollars, but Houston homeowners often make avoidable mistakes that hurt their chances of success. Here are the top 5 mistakes to avoid in 2025:

1. Missing the Deadline

The deadline to file a property tax protest in Houston is typically May 15 or 30 days after you receive your assessment notice, whichever is later. Missing this deadline means you lose your right to appeal for the year. Set reminders and act early to avoid this costly oversight.

2. Failing to Gather Evidence

Simply claiming your home is overvalued isn’t enough. You need solid evidence, such as recent comparable sales (comps) in your neighborhood, photos of property damage, or appraisals. Without this, your protest is unlikely to succeed.

3. Overlooking Exemptions

Many homeowners forget to apply for exemptions like the homestead exemption, which can significantly reduce your taxable value. In 2025, ensure you’ve claimed all eligible exemptions before filing your protest.

4. Not Understanding the Process

The property tax appeal process can be confusing, especially for first-timers. Mistakes like submitting incomplete forms or not knowing how to present your case to the appraisal review board (ARB) can weaken your appeal.

5. Going It Alone Without Professional Help

While DIY appeals are possible, they often take hours of research and preparation. Legal firms can charge thousands of dollars for their services. TaxLasso offers a superior alternative: it takes just 5 minutes to submit your protest, provides professional-level insights, and saves you thousands compared to legal firms.

By avoiding these common mistakes, you can maximize your chances of a successful property tax protest in 2025. For a streamlined, cost-effective solution, consider using TaxLasso to handle your appeal with ease and confidence.
