Check
Enter your notice. We screen your assessed value against recent sales and neighborhood comps and tell you plainly whether a protest looks worth your time — sometimes the answer is no.
For Texas homeowners
Your county may think your house is worth more than it is.
Most Texas homeowners never check — and never protest. Those who do win a reduction most of the time. ProtestKit checks your assessment, builds your evidence, and keeps you on the deadline. You file it yourself and keep every dollar you save.

Estimate your protest upside
Enter what your appraisal notice says. We'll estimate the reduction homeowners like you typically win, your real filing deadline, and what a win is worth per year.

Secure checkout by Stripe. You'll answer three quick questions about your property, and your kit intake arrives by email.
Estimates use a typical combined tax rate for your county and statewide protest outcomes (average 7.6% value reduction among protesters, 77% win rate). Your outcome depends on your property and evidence. This is an estimate, not a promise or appraisal.
How ProtestKit works
You stay the filer. ProtestKit is software that does the research and paperwork with you — it never represents you, and nothing gets submitted without your click.
Build
We assemble your evidence packet: a comparable-sales table, an unequal-appraisal argument where the numbers support it, a photo checklist, and a one-page summary the appraiser can actually read.
File & present
County-specific filing instructions and portal links, your exact filing deadline, and talking points for the informal conference, plus what to expect if your case goes to an ARB hearing. You review and submit everything yourself.
What your evidence packet looks like
Appraisal districts decide on evidence. Here's the core of what the kit produces — sample data shown for illustration.
| Address | Sold | Sq ft | Sale | $ / sq ft |
|---|---|---|---|---|
| 1418 Bay St | Mar | 1,842 | $318,000 | $172.64 |
| 2209 Palm Ave | Feb | 1,910 | $325,500 | $170.42 |
| 711 Cypress Ln | Mar | 1,795 | $299,900 | $167.02 |
| 3304 Oleander | Apr | 1,860 | $312,000 | $167.74 |
| 902 Terracotta | Feb | 1,888 | $321,000 | $170.02 |
Your subject property, assessed at $352,000 for 1,870 sq ft, works out to $188.24 / sq ft — about 11% above every comparable sale in the sample set. That's the argument, in one table.

The Texas protest calendar
Miss the filing deadline and you generally wait a full year. Here's the sequence.
-
Feb – Apr
Notice of appraised value arrives
Your appraisal district mails your notice. Read it — this is where most people stop, and shouldn't.
-
By May 15*
File your protest
*Or within 30 days of the notice mailing date, whichever is later. Filing is free and can usually be done online through your district's portal.
-
Spring – summer
Informal conference
Most cases settle here. You and an appraiser walk through the evidence — your packet does the talking.
-
15 days' notice
ARB hearing (if needed)
If you don't settle, the Appraisal Review Board schedules a hearing and must give at least 15 days' notice. You can attend in person, by phone, by video, or by written affidavit.
-
After the ruling
Written order
The ARB's order arrives by email or certified mail. Reductions apply to this year's taxes.
Pricing
One flat price. No percentage of your savings, ever.

Immediately
Receipt & intake
Your Stripe receipt arrives by email. The property details you entered at checkout — address, county, assessed value — become your kit intake, so there's nothing to re-type.
-
Within 1 business day
We prepare your packet
We assemble your evidence: a comparable-sales table with verifiable sources, an unequal-appraisal argument where the numbers support it, a photo checklist, and your county's filing instructions and portal links.

You review & file
You stay the filer
You review the packet and file the protest yourself through your county's online portal — usually about fifteen minutes. ProtestKit never files for you and never represents you before the district.
-
At your informal conference
You present the evidence
Your packet includes talking points for the informal conference — where most cases settle — and explains your ARB hearing options if yours doesn't. Questions along the way? Email [email protected].
No outcome is guaranteed — savings depend on your property and evidence — and nothing here is legal, tax, or appraisal advice.

Questions
Can protesting raise my assessed value?
The ARB can consider evidence about your value when you file a protest, so bring your best case — that's what the kit is for. In practice, homeowners who protest with real evidence do it because the odds of a reduction are favorable: in recent Texas data, most protests resulted in a reduction.
What if I missed the May 15 deadline?
If more than a year has passed since you knew you disagreed with a value, or you missed the filing window, options narrow sharply — late protests are generally limited to specific situations like a clerical error or value change. Your kit states your exact filing deadline up front so you don't end up here. Next season's notices go out in early spring.
Is this legal or tax advice?
No. ProtestKit is self-help software. It organizes public data and published process rules, and you make every filing decision. Nothing here is legal, tax, or appraisal advice, and ProtestKit does not represent you before your appraisal district.
Which counties are supported?
Full kits are available in 15 counties: Galveston, Harris, Brazoria, Fort Bend, Montgomery, Dallas, Tarrant, Collin, Denton, Travis, Williamson, Bexar, Hidalgo, Cameron, and El Paso. See Counties we serve. The free estimator works anywhere in Texas; if your county isn't listed, email [email protected] before buying.
What are my actual odds?
Statewide, roughly 60–80% of protests result in a reduction, with an average assessed-value reduction around 7.6% among protesters in a recent 17-county study. Your odds depend on your evidence — a solid comparable-sales packet is the single biggest lever you control.
Do I have to go to a hearing?
Usually not. Most cases settle at the informal conference. If yours doesn't, you can attend the ARB hearing in person, by phone, by videoconference, or by filing a written affidavit — no courtroom required.
The county counts on you not filing.
Most of your neighbors won't protest this year. The free check takes about a minute.
