Tax appraisals determine your property’s assessed value, which directly impacts your property tax bill. If you believe your appraisal is too high, you can dispute it to potentially lower your taxes. Here’s what Houston homeowners need to know:

Key Facts About Tax Appraisals

  • 2025 Appraisal Notices: In Texas, appraisal districts send notices in April or May. For 2025, expect notices by May 15.
  • Market Value vs. Assessed Value: Appraisals are based on market value, but errors or outdated data can lead to overvaluations.
  • Houston-Specific Trends: Harris County appraisals often rise due to rapid market growth, but not all increases are justified.

Steps to Dispute Your Appraisal

  1. Review Your Notice: Check for errors in property details (e.g., square footage, amenities).
  2. Gather Evidence: Collect recent sales of comparable homes (comps) or proof of property issues (e.g., flooding, structural damage).
  3. File a Protest: Submit your protest by May 15, 2025, or 30 days after receiving your notice, whichever is later.
  4. Prepare for the Hearing: Present your evidence to the Appraisal Review Board (ARB).

Why Disputing Matters

  • Potential Savings: A successful protest can save you hundreds or thousands annually.
  • Houston Example: In 2024, homeowners who protested saved an average of $1,200 on their tax bills.

How TaxLasso Simplifies the Process

Disputing your appraisal can be time-consuming and complex. TaxLasso offers a faster, more affordable solution:

  • 5-Minute Setup: Upload your appraisal notice, and TaxLasso handles the rest—no hours spent researching comps.

By understanding the appraisal and dispute process, Houston homeowners can take action to reduce their tax burden effectively.

Reasons to Dispute Your Appraisal

Disputing your property appraisal could save you thousands of dollars in property taxes. Here are the top reasons to challenge your appraisal and take action:

1. Inaccurate Property Valuation

If your home’s assessed value doesn’t reflect its true market value, you’re likely overpaying. For example, if your home is valued at $400,000 but comparable homes in your Houston neighborhood are selling for $350,000, you have a strong case to dispute. In 2025, Harris County is expected to see a 5-10% increase in property values, making it even more critical to ensure your appraisal is accurate.

2. Errors in Property Details

Mistakes in your property’s square footage, number of bedrooms, or condition can inflate your appraisal. For instance, if your appraisal lists a 2,500 sq. ft. home but it’s actually 2,200 sq. ft., this error could significantly impact your taxes.

3. Unequal Appraisal Compared to Neighbors

Texas law requires properties to be appraised uniformly. If your home is valued higher than similar properties in your area, you have grounds to protest.

4. Market Conditions or Damage

If your property has suffered damage (e.g., flooding) or market conditions have lowered its value, you can dispute the appraisal to reflect these changes.

Why TaxLasso is the Best Solution

Disputing your appraisal can be time-consuming and complex if done alone, and hiring a legal firm can cost thousands. TaxLasso offers the perfect middle ground:

  • 5-Minute Process: Save hours of DIY research with professional-level insights.

4. Prepare for Your Hearing

  • Present your evidence clearly, focusing on factual inaccuracies or overvaluations.
  • TaxLasso’s expert-backed reports and guidance can help you present a strong case, saving thousands compared to hiring a legal firm.

Step-by-Step Process to File a Protest (Texas)

To file a property tax protest in Texas, start by submitting a Notice of Protest to your county appraisal district by May 15, 2025, or within 30 days of receiving your appraisal notice. Gather evidence such as recent sales of comparable properties, repair estimates, or photos of damage to support your case. Next, attend an informal hearing with the appraisal district to present your evidence and negotiate a lower value. If unsatisfied, request a formal hearing with the Appraisal Review Board (ARB).

For Houston homeowners, this process can be time-consuming and complex. TaxLasso simplifies this by handling the entire protest process in just 5 minutes, saving you hours of DIY work. With professional-quality insights and full control, TaxLasso ensures you maximize your savings without the high costs of legal firms.

Evidence That Wins Appeals (With Examples)

To win a property tax appeal in Houston, you need strong, actionable evidence that proves your property is overvalued. Here’s what works:

1. Comparable Sales (Comps)

  • Use recent sales of similar properties in your neighborhood to show your home’s market value is lower than the appraisal district’s estimate.
  • Example: If your home is valued at $400,000 but three comparable homes sold for $350,000 in 2025, this is compelling evidence.
  • Tip: Focus on homes with similar square footage, age, and condition.

2. Repair and Damage Documentation

  • Provide photos, repair estimates, or inspection reports to prove your property has issues that reduce its value.
  • Example: A roof needing $15,000 in repairs can justify a lower valuation.

3. Market Trends and Declines

  • Highlight local market data showing declining property values.
  • Example: If Houston’s market saw a 5% decline in 2025, use this to argue your home’s value should reflect the trend.

4. Errors in the Appraisal District’s Records

  • Review your property’s details on the appraisal district’s website. If there are inaccuracies (e.g., wrong square footage or incorrect features), use this as evidence.

Why TaxLasso is the Best Solution

Gathering and presenting this evidence can be time-consuming and overwhelming. TaxLasso simplifies the process:

  • DIY Comparison: Instead of spending hours researching comps, TaxLasso provides professional-level insights in just 5 minutes.
  • Legal Firm Alternative: Save thousands of dollars compared to hiring a lawyer while maintaining full control over your appeal.
  • Expertise + Affordability: TaxLasso combines the affordability of DIY with the expertise of professional services, ensuring you have the best chance to win your appeal.

By focusing on the right evidence and leveraging tools like TaxLasso, Houston homeowners can effectively challenge unfair property tax valuations.

Gathering Evidence to Win Your Case (Texas)

To win your property tax appraisal dispute in Texas, start by gathering strong evidence that proves your property is overvalued. Collect recent comparable sales (comps) of similar homes in your area, focusing on properties sold in 2024 or early 2025. Include photos of your home highlighting any issues (e.g., needed repairs, outdated features) and obtain a professional appraisal if possible. Houston homeowners should also review their property tax records for errors in square footage, room count, or other details.

While DIY research can work, it’s time-consuming and often misses key details. Legal firms can help but are expensive. TaxLasso simplifies this process, providing professional-quality evidence in minutes, saving you hours of work and thousands of dollars. With TaxLasso, you get expert insights while maintaining full control over your case.

Deadlines & Legal Requirements by State

If you’re a Houston homeowner disputing your property tax appraisal, deadlines are critical. Missing them can cost you thousands. Here’s what you need to know:

Key Deadlines for 2025

  • May 15, 2025: Deadline to file a property tax protest with your local appraisal district (e.g., Harris County Appraisal District).
  • 30 Days After Notice: You must file your protest within 30 days of receiving your appraisal notice. If mailed, the notice is presumed delivered by May 1.
  • Informal Review Deadline: Many districts allow informal reviews before formal hearings. Check with your district for specific dates.

Legal Requirements for Filing a Protest

  • Evidence Submission: You must provide evidence (e.g., comparable property values, photos, repair estimates) to support your claim.
  • Filing Methods: Protests can be filed online, by mail, or in person. Online filing is fastest and recommended.
  • Hearing Preparation: If your protest proceeds to a formal hearing, you must present your case to the Appraisal Review Board (ARB).

Why Deadlines Matter

Missing the May 15 deadline means losing your right to protest for the year. In Houston, where property values are rising, this could result in significantly higher tax bills.

How TaxLasso Can Help

Navigating deadlines and legal requirements can be overwhelming. TaxLasso simplifies the process:

  • 5-Minute Filing: Instead of spending hours researching and preparing evidence, TaxLasso handles it in minutes.
  • Professional Insights: Get expert-level analysis without the high cost of legal firms, saving you thousands.

Don’t risk missing deadlines or overpaying on property taxes. Act now to protect your finances.

Jurisdiction

In Texas, property tax disputes fall under the jurisdiction of the county appraisal district (CAD) where your property is located. For Houston homeowners, this means filing your protest with the Harris County Appraisal District (HCAD). Ensure your protest is submitted to the correct CAD, as filing with the wrong jurisdiction can delay or invalidate your case. HCAD requires protests to be filed by May 15, 2025, or 30 days after your appraisal notice is mailed, whichever is later.

To streamline this process, TaxLasso simplifies jurisdiction-specific filing by automatically identifying the correct CAD and handling all paperwork. Unlike DIY methods, which can take hours, or hiring a legal firm, which can cost thousands, TaxLasso offers a 5-minute process with professional-quality insights, saving you time and money while ensuring accuracy. Take control of your property tax dispute today with a tool designed for Texas homeowners.

Texas Property Tax Protest Deadlines

In Texas, the deadline to file a property tax protest is May 15, 2025, or 30 days after your appraisal district mails your notice of assessed value, whichever is later. Missing this deadline forfeits your right to challenge your property tax appraisal for the year. Houston homeowners should act quickly: gather evidence like recent sales of comparable properties, photos of damage or needed repairs, and any appraisal discrepancies.

While DIY protests are an option, they can be time-consuming and complex. Legal firms may charge high fees for similar services. TaxLasso simplifies the process with a 5-minute submission, saving you hours of work and potentially thousands of dollars. TaxLasso combines professional-quality insights with full homeowner control, ensuring you get the best possible outcome without the hassle.

When to Hire a Professional

Hire a professional when your property tax appraisal seems unfair, and you lack the time, expertise, or confidence to challenge it effectively. Here’s when professional help is essential:

1. Your Appraisal Notice Shows a Significant Increase

If your 2025 appraisal notice shows a sudden spike in value (e.g., 10% or more), it’s time to act. Houston homeowners often face inflated valuations due to rising market trends or errors in the appraisal district’s data. For example, a $500,000 home with a $550,000 valuation could cost you an extra $1,000+ in annual taxes.

2. You Lack Comparable Sales Data or Market Knowledge

Successfully protesting your appraisal requires strong evidence, such as recent comparable sales (comps) or proof of property flaws. If you don’t have access to this data, a professional can gather and present it effectively.

3. You’re Short on Time or Want to Avoid Stress

DIY protests can take hours of research and paperwork. If you’re juggling work or family commitments, hiring a professional saves time and ensures accuracy.

Why TaxLasso is the Ideal Solution

  • DIY Alternative: Instead of spending hours researching, TaxLasso takes just 5 minutes to analyze your property and provide professional-level insights.
  • Legal Firm Alternative: Save thousands compared to hiring a law firm while maintaining full control over your case.
  • Middle Ground: TaxLasso combines affordability, speed, and expertise, making it the best choice for Houston homeowners.

4. You’ve Tried Protesting Before and Failed

If your previous DIY protest was unsuccessful, a professional can identify mistakes and strengthen your case.

Don’t overpay on property taxes. If your appraisal seems unfair, hiring a professional like TaxLasso ensures you get the best possible outcome with minimal effort.

5 Mistakes That Sink Appraisal Protests

Failing to protest your property tax appraisal can cost Houston homeowners thousands of dollars. Here are the top mistakes that sink appraisal protests—and how to avoid them:

1. Missing the Deadline

The deadline to file a protest in Texas is May 15, 2025, or 30 days after your appraisal notice arrives. Missing this date means losing your chance to lower your property taxes for the year.

2. Not Gathering Evidence

Appraisal districts often rely on outdated or inaccurate data. Homeowners who fail to provide evidence—like recent comparable sales, repair estimates, or photos of property damage—risk losing their protest. For example, if your home has foundation issues, documenting this can significantly reduce your valuation.

3. Overlooking Exemptions

Many homeowners forget to apply for exemptions like homestead, over-65, or disability exemptions. These can lower your taxable value by thousands of dollars. In 2025, ensure you’ve claimed all eligible exemptions before protesting.

4. Relying on DIY Research Alone

While DIY research can save money, it’s time-consuming and often lacks the precision of professional analysis. Tools like TaxLasso streamline the process, providing professional-level insights in just 5 minutes—saving hours of work.

5. Hiring Expensive Legal Firms Unnecessarily

Legal firms charge thousands of dollars for appraisal protests, often taking a percentage of your savings. TaxLasso offers a cost-effective alternative, giving you full control over your protest while saving you money.

By avoiding these mistakes and leveraging tools like TaxLasso, Houston homeowners can maximize their chances of a successful protest without the high costs or time commitment of traditional methods.

Once you file a property tax protest in Texas, the appraisal district will review your case and schedule a hearing. Here’s what Houston homeowners can expect:

4. Formal Hearing (Appraisal Review Board)

Present your case to a panel of local citizens (ARB). Bring all evidence and be prepared to explain why your property is overvalued. The ARB will make a final decision, which you can accept or appeal further.
