What Is a Notice of Assessed Value?

A notice of assessed value is an official document sent by your local appraisal district, such as the Harris County Appraisal District (HCAD). This document states the assessed value of your property for tax purposes, determining how much you’ll pay in property taxes for the year. For Houston homeowners, this notice typically arrives in April 2025, and it’s crucial to review it carefully to ensure accuracy.

Key Details in the Notice:

  • Assessed Value: The dollar amount assigned to your property by the appraisal district.
  • Market Value: The estimated amount your property would sell for in the current market.
  • Exemptions: Any tax breaks you qualify for, such as homestead exemptions, which reduce your taxable value.
  • Deadline to Protest: In 2025, Houston homeowners typically have until May 15 (or 30 days after the notice is mailed) to file a protest if they believe the assessed value is incorrect.

Why It Matters:

  • Higher Assessed Value = Higher Taxes: If your property’s assessed value increases, your property taxes will likely rise.
  • Errors Are Common: Appraisal districts may overvalue your property or fail to apply exemptions correctly.
  • Protesting Can Save Money: Successfully challenging your assessed value can lower your tax bill.

What to Do Next:

  1. Review Your Notice: Check for errors in property details, exemptions, or valuation.
  2. Compare with Market Data: Use recent sales of similar properties in your area to determine if your assessed value is fair.
  3. File a Protest: If you find discrepancies, file a protest before the deadline.

How to Read Your Notice (With Examples)

Understanding your notice of assessed value is critical to ensuring you’re not overpaying on property taxes. Here’s how to read it and take action:

Key Sections to Review

  1. Assessed Value:

    • This is the value the appraisal district assigns to your property. For example, if your home’s assessed value is $350,000 in 2025, this is the figure used to calculate your taxes.
    • Compare this to recent sales of similar homes in your area. If comparable homes sold for $320,000, your assessment might be too high.

  2. Exemptions Applied:

    • Check if your homestead exemption (or others, like over-65 or disability) is listed. A $100,000 homestead exemption reduces your taxable value to $250,000.
    • If exemptions are missing, contact the appraisal district immediately.

  3. Market Value vs. Assessed Value:

    • Market value is what the district believes your home could sell for. Assessed value is often lower due to exemptions or caps.
    • For example, if your market value is $400,000 but your assessed value is $350,000, the latter is used for tax calculations.

What to Do Next

  • Protest if Necessary: If your assessed value seems too high, gather evidence like recent sales data or repair estimates.
  • Use Tools Like TaxLasso: Instead of spending hours researching DIY comparisons or thousands on legal firms, TaxLasso provides professional-level insights in just 5 minutes. It’s the ideal middle ground—affordable, fast, and effective.

By understanding your notice and taking action, you can potentially save thousands on your 2025 property taxes.

Assessed Value vs. Market Value: Key Differences

Understanding the difference between assessed value and market value is critical for Houston homeowners, especially when reviewing your 2025 notice of assessed value. Here’s what you need to know:

  • Assessed Value: This is the value assigned to your property by the Harris County Appraisal District (HCAD) for tax purposes. It’s typically a percentage of the appraised value and is used to calculate your property taxes. For instance, in 2025, HCAD may assess your home at 85% of its appraised value.
  • Market Value: This is the price your home would likely sell for on the open market, based on recent sales of comparable properties in your area. Market value fluctuates with demand, location, and market conditions.

Key Differences:

  1. Purpose:

    • Assessed value determines your property tax bill.
    • Market value reflects what buyers are willing to pay for your home.

  2. Calculation:

    • Assessed value is based on HCAD’s appraisal, which may not always align with current market trends.
    • Market value is influenced by real-time factors like neighborhood desirability and economic conditions.

  3. Impact on Taxes:

    • A higher assessed value means higher property taxes, even if your home’s market value hasn’t increased proportionally.

Why This Matters for Houston Homeowners

If your 2025 assessed value seems too high, you can protest it to potentially lower your tax bill. However, gathering evidence like comparable sales data can be time-consuming if done DIY. Hiring a legal firm can cost thousands.

TaxLasso offers a better solution:

  • 5-Minute Process: Submit your property details, and TaxLasso provides professional-level insights instantly.
  • Affordable Expertise: Save thousands compared to legal firms while maintaining full control over your protest.

By understanding these key differences and leveraging tools like TaxLasso, you can take action to ensure your assessed value is fair and your taxes are manageable.

Why Did My Assessed Value Change?

Your assessed value changed because the Harris County Appraisal District (HCAD) reevaluated your property based on market trends, improvements, or other factors. This reassessment happens annually, and the 2025 notice reflects the value as of January 1, 2025. Here’s why your assessed value might have increased or decreased:

Key Reasons for Changes in Assessed Value

  1. Market Trends: If home prices in your Houston neighborhood rose in 2024, your assessed value likely increased to reflect higher market values.
  2. Property Improvements: Adding a pool, renovating your kitchen, or expanding your home can raise your assessed value.
  3. HCAD Adjustments: HCAD may adjust values based on new data, such as recent sales of comparable homes in your area.
  4. Exemptions or Errors: If you lost a homestead exemption or HCAD made a mistake in their calculations, your assessed value could change unexpectedly.

What Can You Do About It?

If your assessed value seems too high, you have options:

  • File a Protest: Houston homeowners can protest their assessed value with HCAD. You’ll need evidence, such as recent sales of comparable homes or photos showing property issues.
  • Use TaxLasso: Instead of spending hours researching comparable sales or paying thousands to a legal firm, TaxLasso simplifies the process. In just 5 minutes, TaxLasso provides professional-level insights and handles your protest, saving you time and money.
  • Check for Errors: Review your property details on HCAD’s website. Incorrect square footage or missing exemptions can lead to overvaluation.

Critical Deadlines You Can't Miss

When it comes to your property tax assessment in Houston, timing is everything. Missing key deadlines can cost you thousands of dollars in overpaid taxes. Here’s what you need to know to act fast and protect your wallet:

1. Notice of Assessed Value Deadline (May 15, 2025)

  • What to Do: Review your Notice of Assessed Value as soon as you receive it (typically in April).
  • Why It Matters: If you believe your property is overvalued, you must act quickly. The deadline to file a protest with the Harris County Appraisal District (HCAD) is May 15, 2025. Missing this date means you lose your chance to challenge your assessment for the year.

2. Informal Review Deadline (May 1, 2025)

  • What to Do: Before filing a formal protest, consider requesting an informal review with HCAD.
  • Why It Matters: This step can resolve issues faster and often avoids the need for a formal hearing. The deadline for informal reviews is typically May 1, 2025, but confirm with HCAD as dates may vary.

3. Formal Protest Hearing Deadline (May 15, 2025)

  • What to Do: If the informal review doesn’t resolve your concerns, file a formal protest by May 15, 2025.
  • Why It Matters: This is your last chance to present evidence (e.g., comparable sales, repair estimates) to lower your property’s assessed value.

4. Payment Deadline (January 31, 2026)

  • What to Do: Even if you’re protesting, you must pay your property taxes by January 31, 2026, to avoid penalties.
  • Why It Matters: If your protest is successful, you’ll receive a refund for any overpayment.

How Assessed Value Impacts Property Taxes

The assessed value of your property directly determines how much you pay in property taxes. In Houston, your tax bill is calculated by multiplying the assessed value by the local tax rate. If your assessed value increases, your property taxes will likely rise unless you take action.

Key Facts for Houston Homeowners

  • 2025 Assessments: Harris County Appraisal District (HCAD) will release 2025 assessed values in early 2025. These values are based on market trends and property conditions as of January 1, 2025.
  • Tax Rate Impact: Houston’s average property tax rate is approximately 2.23%. For example, if your home’s assessed value is $300,000, your annual tax bill would be around $6,690. A 10% increase in assessed value could raise your taxes by $669.
  • Exemptions Matter: Homestead exemptions can reduce your taxable assessed value. For 2025, ensure you’ve applied for all eligible exemptions, such as the general homestead exemption, which caps increases at 10% annually.

What You Can Do

  1. Review Your Notice: Carefully check your 2025 notice of assessed value for accuracy. Look for errors in property details or valuation.
  2. Protest if Necessary: If your assessed value seems too high, file a protest with HCAD. You’ll need evidence, such as recent comparable sales or photos of property issues.
