Short answer: To compare your home's value with Texas county appraisal data, start by reviewing your appraisal district's website for your property record and recent sales of comparable homes. Look for properties similar to yours that were assessed lower or sold for less. Specialized online tools can also quickly identify potential over-assessments by analyzing public data and finding "equal and uniform" discrepancies.
- Review your county appraisal district's website for your property.
- Identify comparable homes with lower assessed values or sales prices.
- Focus on "equal and uniform" appraisal discrepancies.
- Utilize online tools to streamline data analysis and find your gap.
- Understand key protest deadlines, typically May 15.
- Gather strong evidence to support any protest claim.
Why Does My County's Assessed Value Matter?
Your county appraisal district (CAD) determines your home’s assessed value each year, which is the basis for your property taxes. If this value is higher than what your home is actually worth, or higher than similar homes around you, you could be paying more in taxes than you should. This difference is often called the “gap.” Understanding how to compare your home’s value to the CAD’s data is your first step in ensuring you’re not overpaying.
Texas law requires that your property be appraised at its market value. However, mass appraisal techniques used by CADs aren’t always perfect, leading to potential discrepancies for individual homes. For the 2026 tax year, it’s especially important to review your appraisal notice carefully.
How Can I Get My County's Property Appraisal Data?
The primary source for your property’s appraisal data is your local county appraisal district’s website. For example, if you’re in Travis County, you’d visit TCAD.org; for Dallas County, it’s DCAD.org. Most CAD websites offer a property search tool where you can enter your address to find:
- Your property’s assessed value and characteristics (square footage, lot size, year built).
- A list of recent sales (comparable sales or “comps”) used to value properties in your area.
- Assessed values for neighboring properties or other comparable homes.
When reviewing this data, pay close attention to the “Appraised Value” and the “Market Value” listed. Also, look at the values of homes similar to yours in your neighborhood. You’re specifically looking for evidence that your home is appraised at a higher value than comparable properties, which is the basis for an “equal and uniform” protest under Texas Tax Code 41.43(b)(3).
DIY vs. Specialized Tools: Finding Your "Gap"
Comparing your home’s value with county data can be a detailed process. You can certainly do it yourself, but specialized tools can make it much easier to identify discrepancies.
DIY Approach:
- Gather your data: Download your property record and sales data from your CAD website.
- Identify comps: Manually search for 5-10 homes that are similar in age, size, condition, and location to yours.
- Compare values: Look at the assessed values of these comparable homes and any recent sales prices. If similar homes are assessed significantly lower than yours, or if recent sales in your area suggest a lower market value, you might have a case.
- Use online real estate sites: Sites like Zillow or Redfin can give you an estimated market value, but remember these are just estimates and may not reflect the specific data your CAD uses or the legal standards for protest.
Using Specialized Tools:
Online tools designed specifically for property tax protests can automate much of this research. For example, the Tax Gaps TX free home check tool helps homeowners in Travis (TCAD) and Dallas (DCAD) counties quickly find their estimated over-assessment gap. By entering your address, the tool analyzes public appraisal data and identifies comparable homes assessed for less than yours, highlighting potential “equal and uniform” issues. This can save you hours of manual research and provide a clear picture of whether a protest is worthwhile.
What if I Find a Discrepancy? Protesting Your Appraisal
If your comparison reveals that your home is over-assessed, you have the right to protest your appraisal with your county appraisal district. The standard deadline to file a protest is May 15 or 30 days after your Notice of Appraised Value was mailed to you, whichever is later. Always verify the exact deadline with your specific CAD.
Your protest must be based on solid evidence. This evidence typically includes:
- Comparable sales data: Recent sales of similar homes in your area that sold for less than your assessed value.
- Equal and uniform data: Assessed values of comparable homes that are lower than yours, even if their market value is similar.
- Property condition: Photos or reports documenting any damage or needed repairs that negatively impact your home’s value.
After filing your protest, you’ll typically have an informal meeting with an appraiser, followed by a formal hearing with the Appraisal Review Board (ARB) if an agreement isn’t reached. For homes valued over a certain amount, binding arbitration is another option.
Key Texas Property Tax Details to Remember
Understanding a few specific Texas property tax rules can also help you in your comparison and protest efforts:
- Homestead Exemption: Make sure you have your homestead exemption filed on your primary residence. This reduces the taxable value of your home.
- 10% Homestead Cap: For qualifying homesteads, the appraised value for tax purposes cannot increase by more than 10% per year, regardless of how much the market value increases. This cap applies to the assessed value, not necessarily the market value.
- Equal and Uniform: This is a powerful protest argument under Texas Tax Code 41.43(b)(3), asserting that your property is appraised at a higher value than a reasonable number of comparable properties.
Remember, appraisal values, deadlines, and exemption amounts can change yearly. Always refer to your county appraisal district’s official website or the Texas Comptroller of Public Accounts website for the most current information.

Frequently asked questions
What is an "equal and uniform" protest in Texas?
An "equal and uniform" protest argues that your property is appraised at a higher value than a reasonable number of comparable properties in your neighborhood, even if your market value assessment seems correct. This is a common and effective basis for protest under Texas Tax Code 41.43(b)(3).
How does the 10% homestead cap work in Texas?
The 10% homestead cap limits the increase in your home's assessed value for tax purposes to no more than 10% per year, provided you have a homestead exemption. This cap only applies to your primary residence and can significantly reduce your tax burden in rapidly appreciating markets.
Can I protest my home's value after the deadline?
Generally, no. The protest deadline (May 15 or 30 days after your appraisal notice, whichever is later) is strict. Missing it typically means you lose your right to protest for the current tax year, though there are very limited exceptions for specific errors or certain property types.
What kind of evidence do I need to protest my home's value?
Effective evidence includes recent sales data for comparable homes that sold for less than your assessed value, assessed values of similar homes that are lower than yours, and documentation of any physical damage or defects that reduce your home's market value.
