Texas Property Tax Protest Deadline: May 15, 2026 - File Now

The Texas property tax protest deadline for 2026 is May 15, 2026 — just 35 days away. Texas homeowners have until this date to formally challenge their property's assessed value with their local appraisal district. Missing this deadline means accepting your current assessment and paying potentially thousands more in property taxes.

Key Facts: Texas law requires all property tax protests to be filed by May 15 (or the next business day if May 15 falls on a weekend). Late filings are only accepted in very limited circumstances involving military deployment or other extraordinary situations.

Why May 15 Matters for Your Property Taxes

Property tax bills in Texas are calculated using your home's assessed value as of January 1, 2026. Appraisal districts across Texas — from Harris County (HCAD) to Travis County (TCAD) to Collin County — have already mailed notices showing their valuation of your property.

The difference between protesting and not protesting can be substantial. According to Texas Comptroller data, successful protests in 2025 reduced property values by an average of $25,000 to $45,000, depending on the county. For a home with a $400,000 assessment, a successful $30,000 reduction could save approximately $600-900 annually in property taxes.

How to File Your Texas Property Tax Protest

Texas homeowners have several options for filing their protest before the May 15 deadline:

Online Filing (Fastest Method)

Most Texas appraisal districts now accept online protests:

• Harris County: File at hcad.org using the "Protest Online" portal
• Dallas County: Submit through dallascad.org's e-file system
• Travis County: Use traviscad.org's online protest form
• Collin County: File at collincad.org through their digital platform

Mail or In-Person Filing

Traditional filing methods remain available:

• Download protest forms from your county's appraisal district website
• Complete the form with your property details and reason for protest
• Mail or deliver to your appraisal district office before May 15

What Evidence Strengthens Your Protest

Texas appraisal districts consider several types of evidence during the protest process:

Comparable Sales Data

Recent sales of similar homes in your neighborhood provide market evidence. Look for properties that:

• Sold within the last 12 months
• Have similar square footage, lot size, and features
• Are located within 0.5-1 mile of your home

Property Condition Issues

Document any factors that may reduce your home's value:

• Needed repairs or maintenance issues
• Outdated systems (HVAC, plumbing, electrical)
• Functional obsolescence or unusual features

Market Analysis

Professional appraisals or broker price opinions can provide additional market perspective, though they're not required for filing a protest.

Important Deadlines and Next Steps

After filing your protest by May 15, the timeline typically follows this schedule:

• May 16-July 15: Informal review period - some counties offer informal conferences
• July-September: Formal hearings scheduled with Appraisal Review Board (ARB)
• October-November: Final property tax bills mailed based on protest outcomes

Texas homeowners who miss the May 15 deadline have very limited options. Counties may accept late protests only for military personnel on active duty, property owners who didn't receive proper notice, or in cases of natural disaster.

Filing Options and Costs

Texas homeowners can choose from several approaches:

• DIY Filing: Use free county resources and file independently
• Property Tax Consultants: Hire professionals who typically charge 25-50% of tax savings
• Document Preparation Services: Services like FairPath ($249 flat fee) prepare professional evidence packets
• Property Tax Attorneys: Legal representation for complex cases

Cost Consideration: Filing a protest with your county appraisal district is always free. Any fees are for professional assistance in preparing your case.
