About TexasTaxSignal

What is TexasTaxSignal?

TexasTaxSignal is a free property tax analysis tool for Texas property owners. We help you decide whether protesting your property taxes is worth your time by analyzing your property against county data, neighborhood comparisons, and year-over-year trends. We provide judgment and clarity—not protest services.

Is TexasTaxSignal legit?

Yes. TexasTaxSignal uses real data from Texas Central Appraisal Districts (CADs) to analyze your property. We don't file protests on your behalf, take percentages of your savings, or make guarantees. We simply help you make an informed decision about whether to protest. Our analysis is free during our preview period.

Is TexasTaxSignal free?

Yes, TexasTaxSignal is completely free until April 2026. You get full property analysis reports including year-over-year comparisons, neighborhood data, and a clear recommendation—all at no cost. After April 2026, Basic reports will be $9 and Pro reports with strategy guidance will be $29.

Who runs TexasTaxSignal?

TexasTaxSignal was built by Texas property owners who were frustrated with the lack of transparent, unbiased information about property tax protests. We're a small team focused on helping property owners make better decisions—not a protest company trying to upsell services.

Are you a property tax protest company?

No. We do not file protests, attend hearings, or represent you before the CAD or ARB. We're a decision tool that helps you understand if protesting is worth your time before you invest effort into the process. If you decide to protest, you'll do it yourself or hire a separate company.

How It Works

How does TexasTaxSignal analyze my property?

We pull your property data from your county's Central Appraisal District, then analyze it against several factors: year-over-year assessment changes, how your $/sqft compares to similar properties in your neighborhood, recent sales data, and historical protest success rates in your area. This gives you a data-driven recommendation.

What data do you use for the analysis?

We use official data from Texas Central Appraisal Districts (CADs) including property assessments, land and improvement values, building characteristics, and neighborhood boundaries. We also analyze public sales records and market trends. All data comes from authoritative public sources.

How accurate is your recommendation?

Our recommendations are based on the same data appraisers use, analyzed against proven indicators of successful protests. While we can't guarantee outcomes (no one can), our analysis considers the factors that matter most: assessment anomalies, neighborhood comparisons, and YoY increases. We're transparent about our reasoning so you can judge for yourself.

How long does the analysis take?

About 30-60 seconds. Enter your address, we auto-detect your county, pull your property data, and generate your analysis. You'll get a clear verdict (Worth Protesting / Maybe / Not Worth It) along with the specific reasons why.

What counties do you support?

We currently support 46 Texas counties covering over 6.5 million homes. 12 counties have full live data: Harris (Houston), Dallas, Tarrant (Fort Worth), Bexar (San Antonio), Travis (Austin), Collin (Plano/Frisco), Denton, Fort Bend, Williamson, Brazoria, Galveston, and Hays. More counties are being added regularly.

Property Tax Basics

Should I protest my Texas property taxes in 2026?

It depends on your specific situation. Key indicators that protesting is worth it: your assessment increased more than 10% year-over-year, your property is valued higher than similar homes in your neighborhood, or your assessment exceeds recent comparable sales. TexasTaxSignal analyzes these factors and gives you a personalized recommendation.

What is the success rate for Texas property tax protests?

Texas property tax protest success rates are very high at informal hearings—typically 70-90% depending on the county. Harris County sees about 85% success, Travis County around 88%. However, 'success' doesn't always mean big savings. Having valid grounds matters more than simply filing. That's why we help you identify IF you have valid grounds first.

How much can I save by protesting?

The average successful protest in Texas saves homeowners $800-$1,500 per year in property taxes. However, this varies widely by county and property. High-growth areas like Collin, Travis, and Hays counties often see larger savings due to rapid assessment increases. Your actual savings depend on how much your assessment exceeds fair market value.

Can I protest my property taxes every year?

Yes, and you should review your assessment every year. Property values change annually, and appraisal districts can make new errors each year. Even if you protested last year, new factors may make this year worth protesting too. TexasTaxSignal helps you evaluate each year's assessment independently.

What is market value vs. assessed value?

Market value is what your property would sell for on the open market. Assessed value is what the appraisal district says it's worth for tax purposes. Texas law says assessed value should equal market value as of January 1st. If your assessed value is higher than true market value, you have grounds to protest.

What is the homestead cap?

Texas limits annual assessment increases to 10% for homestead properties (your primary residence). This means even if your market value jumped 20%, your taxable value can only increase 10% from last year. Investment properties don't have this protection, which is why investors often see larger increases.

Filing a Protest

When is the Texas property tax protest deadline for 2026?

The general Texas property tax protest deadline is May 15, 2026, or 30 days after your appraisal notice date, whichever is later. You must file your protest with your county's Central Appraisal District (CAD) before this deadline. Don't wait—file as soon as you receive your notice to get earlier hearing dates.

How do I file a property tax protest in Texas?

Most Texas counties allow online filing through their CAD website. You can also file by mail, fax, or in person. You'll need to complete a Notice of Protest form and check the box for 'Value is over market value' or 'Value is unequal compared with other properties.' No evidence is required to file—just to present at your hearing.

What evidence do I need for a property tax protest?

The most effective evidence includes: comparable sales (similar properties that sold for less than your assessed value), photos of property condition issues, repair estimates for needed work, and MLS listings showing lower-priced homes in your area. You don't need evidence to file, but you'll need it to win at your hearing.

What is an informal hearing vs. ARB hearing?

An informal hearing is a meeting with an appraiser from your CAD—it's casual, quick (15-30 minutes), and where 70-90% of protests are resolved with some reduction. An ARB (Appraisal Review Board) hearing is more formal, before a panel of citizens, and happens if you're not satisfied with the informal result. Most homeowners never need the ARB hearing.

Can I protest online or do I have to appear in person?

Most Texas counties now offer online/phone hearings as an option. You can choose to appear in person, by phone, or submit evidence online for review. In-person hearings often allow for more negotiation, but online options have become much more common since 2020. Check your county's CAD website for available options.

What happens if I miss the deadline?

If you miss the May 15th deadline (or 30 days after your notice), you generally cannot protest your current year assessment. There are limited exceptions for late-delivered notices or certain errors. Your only option would be to wait until next year. That's why we recommend filing as soon as you receive your notice.

Results & Expectations

What if TexasTaxSignal says 'Not Worth It'?

If we say your property isn't worth protesting, we'll explain exactly why: maybe your assessment is actually below market value, or your increase was minimal, or your $/sqft is already lower than neighbors. This saves you time that would be wasted on a protest likely to fail. We don't just tell you to protest everything.

What does 'Maybe' mean?

'Maybe' means your situation is borderline. You might have some grounds for a small reduction, but it may not be worth your time depending on how you value that time. We'll show you the estimated potential savings so you can decide if it's worth the effort. For a $200 potential savings, some people protest; others don't.

Does TexasTaxSignal guarantee results?

No, and you should be skeptical of anyone who does. We provide data-driven analysis to help you make an informed decision. The actual outcome of your protest depends on many factors including the evidence you present, the appraiser you meet with, and market conditions. We help you understand your odds, not guarantee outcomes.

How are protest results different from tax savings?

Protest results are measured in assessment reduction (e.g., $20,000 off your assessed value). Tax savings depend on your local tax rate (typically 2-3% in Texas). A $20,000 assessment reduction at a 2.5% tax rate = $500 annual savings. We calculate both for you so you understand the real dollar impact.
