You can still challenge
your property tax assessment.

The spring appeal deadline was March 27th. But Kansas law gives you another way to fight an assessment you believe is too high.

It's called Payment Under Protest. We help you prepare your evidence and protest form. You submit it through the county's online portal when you pay your December tax bill. Takes about 10 minutes. No hearing required — the county reviews your evidence in writing.

Am I eligible?

Most Johnson County homeowners qualify. Here's the quick check:

You own property in Johnson County, Kansas
Homeowners, investors, commercial owners — all eligible
You received a 2026 assessment you believe is too high
Compare your appraised value to what similar homes have actually sold for
You have not already filed a spring informal appeal for 2026
Kansas law allows one appeal per property per year — either a spring appeal or a protest, not both

If all three apply to you, you're eligible. That's it.

How it works

Three steps. About 10 minutes of your time. We handle the hard part.

1
Start on JoCoTaxAppeal
Enter your address. We pull your assessment from Johnson County records, find comparable sales in your neighborhood, and show you if you have a case. Takes about 2 minutes.
2
We build your case
We prepare your evidence package — comparable sales analysis, supporting data, and a pre-filled protest form. You review everything and download your documents.
3
Submit through the county portal
Follow our step-by-step guide to file your protest form online at appealportal.jocogov.org when you pay your tax bill. The filing window is November 1 – December 20, 2026. We recommend the evidence-based review — the county reviews your documentation in writing. No meeting, no phone call, no time off work.

Then you're done. The county reviews your evidence and mails you a decision. If you win, your next tax bill is reduced — or you get a refund if you've already paid.

Things you should know

Quick answers to the most common questions.

Do I have to attend a hearing?
No. We recommend the evidence-based review option — you submit your documentation and the county appraiser reviews it in writing. No meeting, no phone call, no time off work. If you prefer, you can also choose a ~20-minute phone call or an in-person meeting at 11811 S. Sunset Drive in Olathe. But most people don't need to.
When can I file?
The filing window is November 1 – December 20, 2026. You submit your protest form through the county's online appeal portal at the same time you pay your first-half property taxes. You can prepare your case with us now and have everything ready to file the moment the window opens.
What if my mortgage company pays my taxes?
You can still file. If at least half your taxes are paid through escrow, your deadline is extended to January 31, 2027. But you need to submit the protest form yourself — your lender's payment alone doesn't count as a protest.
What evidence helps the most?
Comparable sales — recent sales of similar homes in your area that sold for less than your assessed value. That's the #1 thing the county looks at. Photos of property issues (deferred maintenance, damage) help too. This is exactly what we prepare for you.
Can my taxes go UP because I filed?
No. Kansas law protects you. Your assessment can only stay the same or go down. There is zero risk.
What if the county says no?
You have 30 days to appeal to the Kansas Board of Tax Appeals. It's free to file, the hearing is informal, and single-family homes start with a simpler “Small Claims” process. Most people don't need a lawyer.
