How expert strategy, licensed consultants, and better data can give you the edge
Texas has one of the most complex property tax systems in the country. Unlike many states, Texas does not have a state property tax. Instead, property values are set locally by County Appraisal Districts (CADs) — each with its own practices, data sources, and interpretations.
For homeowners, that complexity creates both risk and opportunity. If your home is over-assessed, you have the right to appeal — and when done correctly, a successful appeal can lead to meaningful savings year after year.
Below are insider tips for winning property tax appeals in Texas, along with why working with INTELLI’s licensed property tax consultants, who have access to non-public and private sales data, can significantly improve your outcome.
Understanding Property Tax Assessments
Your property tax bill starts with your assessed value — the CAD’s estimate of what your home is worth for tax purposes. That value is then multiplied by local tax rates set by cities, counties, and school districts.
The problem? Assessments are often built using mass appraisal models that rely on assumptions, incomplete data, and broad averages. These models frequently miss:
- Condition issues
- Location nuances within a neighborhood
- Functional obsolescence
- Private or off-market sales
As a result, many homes are assessed above true market value.
Texas Property Tax Appeals: Step-by-Step Insider Guide
Step 1: Review Your Assessment Carefully
Start by obtaining your property record card from your local CAD. This document contains the data used to assess your home, including:
- Square footage
- Year built
- Improvements
- Construction quality
Then compare your value to similar properties nearby. Large discrepancies are often the first red flag.
Step 2: Identify Errors and Gather Evidence
Common mistakes include incorrect square footage, wrong room counts, or outdated assumptions about condition.
Strong appeals are built on evidence, such as:
- Photos showing condition or deferred maintenance
- Repair or renovation estimates
- Recent comparable sales
This is where INTELLI stands apart. Our licensed consultants don’t rely solely on public records — we incorporate non-public data and private sales not available to homeowners or automated software, giving your appeal a stronger factual foundation.
Step 3: File a Notice of Protest (Texas-Specific)
In Texas, you must file a Notice of Protest by:
- May 15, or
- 30 days after your Notice of Appraised Value is mailed, whichever is later
Many counties allow online filing, but missing this deadline usually means waiting an entire year.
Step 4: Prepare for the Hearing
Whether your appeal is handled informally or goes before an Appraisal Review Board (ARB), preparation matters.
Successful appeals are:
- Clear and well-organized
- Supported by credible, localized data
- Presented professionally and concisely
INTELLI’s licensed property tax consultants know what CADs look for — and how to respond to counterarguments using real market evidence.

Property Tax Appeals Beyond Texas: What’s Universal
While Texas has a unique system, some principles apply nationwide:
- California: Proposition 13 caps annual increases, but reassessments still happen after sales or major improvements. Comparable sales and condition evidence are critical.
- Florida: The Save Our Homes cap limits assessed growth, but market values can still inflate bills. Appeals focus on discrepancies between assessed and market value.
- New York: High tax burdens make grievances common. Strong comparable sales and property-specific issues are key.
Across all states, data quality and preparation determine success.
General Tips for Winning Any Property Tax Appeal

- Know your deadlines
- Don’t rely on automated estimates alone
