Select your county, enter your address, and see how your appraisal compares to similar homes nearby — then generate a ready-to-file protest packet in minutes.
From address to filed protest in four steps — all free, no account required.
Search for your property by street address. We pull live data directly from your county appraisal district's public records.
We find similar homes in your neighborhood and calculate adjusted values using standard Texas appraisal methods.
If your appraisal is higher than the adjusted median of comparable properties, you have grounds to protest under §42.26(a)(3).
Generate a complete evidence package — pre-filled Form 50-132, comp analysis, and legal argument — ready to submit to your appraisal district.
Appraisal districts set values in bulk using mass-appraisal models. Errors are common, and the system is designed so that unchallenged values stick. Most homeowners lose money every year simply because they don't know they have a case — or don't know how to make one.
Other flat-fee documentation services typically charge $50–$80 per filing, and commission-based protest firms can charge up to 40% of your savings. Citizens Tax Protest Service charges nothing. We believe every Texas homeowner deserves access to the same tools, regardless of whether they can afford a professional. If we save you money, we hope you'll consider a small donation to keep the lights on and help us expand to more Texas counties.
Donations are not tax-deductible. No payment is required to use the service — ever.
Texas law requires that your property be appraised at the median level of appraisal of a reasonable sample of comparable properties. If your appraisal district has appraised your home higher than that median — even if the value seems "fair" in the market — you are legally entitled to a reduction. This tool identifies comparable properties in your neighborhood, applies standard Texas adjustment methodology for differences in size, features, and age, and tells you whether you have grounds to protest. The full methodology is shown on the analysis page.
Everything you need to know before you start.
Any Texas homeowner who has received their annual appraisal notice and wants to challenge it — without hiring a professional or paying a commission. If you're comfortable filing your own paperwork and want to keep 100% of any savings you win, this tool is built for you.
It's especially useful if your appraisal went up significantly year-over-year, or if you suspect neighboring homes of similar size and age are appraised lower than yours.
We're Texans who believe every homeowner deserves access to the same protest tools that professionals use — not just those who can afford to pay $50–$80 in flat fees or give up 40% of their savings to a commission firm.
We keep our costs low by using publicly available data from each county's appraisal district. Voluntary donations help us cover operating costs and expand to new counties, but the service will always be free to use.
We currently support Williamson County. We're actively working to add Harris County, Travis County, Brazos County, and additional Texas counties. Donations directly fund that expansion — each new county requires integrating with a different set of data sources.
If your county isn't listed yet, check back soon or consider a donation to help us get there faster.
In Texas, the general deadline to file a protest is May 15, or 30 days after your appraisal notice is mailed — whichever is later. Missing the deadline typically means waiting until next year.
Check the deadline printed on your official appraisal notice, as it may differ slightly by county or property type. Don't wait — the process takes only a few minutes with this tool.
No. Texas law gives every property owner the right to protest their own appraisal and represent themselves at the Appraisal Review Board (ARB) hearing. No license, agent, or legal representation is required.
This tool provides everything you need: the data, the adjusted comparable analysis, and a pre-filled evidence packet that meets Texas ARB standards.
The tool pulls live data directly from your county's public appraisal records and applies the same adjustment methodology appraisal professionals use under Texas Tax Code §42.26. It's not a guess — it's the same math.
That said, the ARB makes the final decision, and outcomes vary depending on the comparable properties available in your neighborhood and the strength of your specific case. The tool will tell you upfront if the data suggests you have strong grounds to protest.
