2025 Protest Deadlines & Key Dates
If you intend to protest your Harris County property tax valuation in 2025, the most critical deadline to remember is May 15, 2025. This is the final day to file your protest with the Harris County Appraisal District (HCAD). Missing this date means you’ll have to wait until 2026 to challenge your property taxes.
Key Dates to Remember:
- April 1, 2025: HCAD sends out property tax appraisal notices. Review your notice promptly to check for accuracy.
- May 15, 2025: Deadline to file your protest with HCAD. You can file online, by mail, or in person.
- May 31, 2025: Informal review deadline. Many homeowners resolve disputes during this phase without a formal hearing.
- July 2025 (exact date TBD): Formal protest hearings begin. If the informal review doesn’t resolve the issue, you’ll present your case to the Appraisal Review Board (ARB).
Why Protest in 2025?
- Save Money: Even a minor reduction in your property valuation can save you hundreds or thousands of dollars annually.
- Correct Errors: HCAD valuations may contain mistakes, such as incorrect square footage or property details.
- Stay Competitive: With rising property values in Harris County, protesting ensures you’re not overpaying compared to similar homes.

Step-by-Step Protest Process
If you’re a Houston homeowner planning to protest your 2025 property tax assessment, here’s a straightforward guide to help you navigate the process efficiently.
1. Review Your 2025 Property Tax Notice
- HCAD will mail out property tax notices in early 2025. Check your assessed value and ensure it aligns with your property’s market value.
- For example, if your home is valued at $400,000 but similar homes in your area are selling for $350,000, you may have grounds for a protest.
2. Gather Evidence to Support Your Protest
- Collect recent sales data of comparable properties (comps) in your neighborhood.
- Document any property damage or issues that could lower your home’s value.
- Use tools like TaxLasso to quickly access professional-level comps and insights in just 5 minutes, saving you hours of research.
3. File Your Protest by the Deadline
- The deadline to file a protest in Harris County is typically May 15, 2025, or 30 days after you receive your notice, whichever is later.
- File online through the Harris County Appraisal District (HCAD) website or use TaxLasso for a streamlined approach.
4. Prepare for Your Hearing
- Choose between an informal hearing (with an appraiser) or a formal hearing (with the Appraisal Review Board).
- Present your evidence clearly and professionally. TaxLasso’s expert-backed reports can assist you in building a strong case without the need for costly legal services.
5. Negotiate or Appeal the Decision
- If you’re unsatisfied with the outcome, you can negotiate further or appeal to the State District Court.
By following this step-by-step process and leveraging tools like TaxLasso, Houston homeowners can effectively challenge their 2025 property tax assessments and potentially save significant amounts.
Evidence to Win Your Protest
To successfully protest your Harris County property tax in 2025, you’ll need compelling evidence to challenge your property’s assessed value. Here’s how to build a strong case:
1. Comparable Sales (Comps)
- Use recent sales of similar homes in your neighborhood (within the last 6-12 months).
- Focus on properties with similar square footage, age, and features.
- For instance, if your home is valued at $400,000 but nearby comps sold for $350,000, this serves as strong evidence.
2. Condition and Repairs
- Document any issues that may lower your home’s value, such as foundation problems, outdated systems, or required repairs.
- Include photos, repair estimates, or inspection reports.
3. Market Trends
- Highlight any declining market trends in your area, such as decreasing home prices or longer days on the market.
- Use data from reputable sources like HAR (Houston Association of Realtors) or Zillow.
4. Appraisal District Errors
- Review your property’s details on the Harris County Appraisal District (HCAD) website.
- Look for inaccuracies in square footage, lot size, or property features that could inflate your valuation.
5. Professional Tools for Success
Instead of spending hours researching comps or paying thousands to a legal firm, consider TaxLasso. TaxLasso simplifies the process:
- Takes just 5 minutes to generate professional-level evidence and protest documents.

2025 Rule Changes & Updates
The 2025 property tax season introduces several rule changes and updates that could impact your tax protest strategy. Here’s what you need to know:
Key Changes for 2025
- Increased Homestead Exemption: The homestead exemption cap has been raised to $125,000 (up from $100,000 in 2024), reducing taxable value for primary residences.
- Deadline Adjustments: The deadline to file a property tax protest is now May 15, 2025 (previously May 1). Mark your calendar to avoid missing this critical date.
- New Valuation Methods: HCAD will implement updated algorithms to assess property values, potentially leading to higher valuations for some homeowners.
How These Changes Affect You
- Higher Valuations: If your property value increases, your tax bill could rise significantly. Protesting your valuation is more important than ever.
- Exemption Benefits: Ensure you’ve applied for the homestead exemption to maximize savings. If you haven’t, act now—it’s free and reduces your taxable value.

Hiring a Professional: Pros and Cons

Common Mistakes to Avoid
Protesting your property taxes in Harris County can save you significant amounts, but many homeowners make common errors that can cost them time, money, or both. Here are the most common mistakes to avoid in 2025:
1. Missing the Deadline
The HCAD typically sets a May 15 deadline for filing protests. Missing this date means losing your chance to challenge your property valuation for the year. Mark your calendar and act early.
2. Not Reviewing Your Notice of Appraised Value
HCAD mails these notices in April. Failing to review your property’s assessed value and comparable sales data can lead to overpaying. Look for errors in square footage, lot size, or property details.
3. Overlooking Comparable Sales
One of the strongest arguments in a protest is demonstrating that similar homes in your area sold for less than your appraised value. Many homeowners skip this step, but tools like TaxLasso make accessing professional-level comps quick and easy.
4. DIY Without Proper Preparation
While DIY protests are an option, they often take hours of research and lack the necessary expertise to negotiate effectively. TaxLasso bridges this gap by offering affordable, expert-backed insights without the high cost of hiring a legal firm.
5. Paying Too Much for Professional Help
Legal firms can charge thousands of dollars for tax protest services. TaxLasso provides the same level of expertise at a fraction of the cost, giving you full control over your protest while saving you money.
6. Ignoring Exemptions
Many homeowners forget to apply for exemptions such as homestead, over-65, or disability exemptions, which can significantly reduce your taxable value. Check your eligibility and file for these before protesting.
By avoiding these mistakes and leveraging tools like TaxLasso, you can maximize your savings and streamline the protest process for your 2025 Harris County property taxes.
Post-Protest Timeline
Understanding the post-protest timeline is essential after filing your 2025 Harris County property tax protest. Here’s what Houston homeowners need to know:
1. Initial Review and Informal Hearing (May-June 2025)
- After filing your protest, HCAD will review your case.
- You’ll receive a notice for an informal hearing, typically scheduled within 4-6 weeks of filing.
- At this stage, HCAD may offer a settlement. If accepted, the process ends here. If not, you’ll proceed to a formal hearing.
2. Formal Hearing (June-July 2025)
- If no agreement is reached during the informal hearing, your case moves to the Appraisal Review Board (ARB).
- You’ll present evidence (e.g., comparable property values, photos, or repair estimates) to support your protest.
- Decisions are usually issued within 1-2 weeks of the hearing.
3. Post-Hearing Outcomes (July-August 2025)
- Accepted Settlement: If the ARB reduces your valuation, your new tax bill will reflect the adjustment.
- Denied Protest: If your protest is denied, you can either accept the decision or escalate to binding arbitration or district court.
4. Tax Bill Issuance (October 2025)
- Regardless of the outcome, your updated property tax bill will be issued in October 2025.
- Payments are due by January 31, 2026, with discounts available for early payment.
