Plan your next step

Estimate a bill and check your assessment

Census survey estimates, 2020–2024. These county medians describe a survey population; they do not establish your home’s correct assessment.

Median home value
$391,200
Median annual taxes paid
$4,447
Estimated effective rate
1.14%

Census home values, Census taxes paid. Last verified 2026-10-24. Rate = median taxes ÷ median home value. Displayed rates are rounded; calculations use the unrounded ratio.

Example at $391,200: $4,447 per year, using the Census estimate.

Is my assessment too high?

At the default market value and bill, both equal the county medians. Being above a median does not establish overassessment. Assessed or taxable values may use a different basis and cannot be compared directly with Census market values.

Appeal timing and filing

An informal real-property appeal is due within 30 days after mailing of the Notice of Appraised Value.

How to file: Johnson County Appraiser’s Office, ATTN: Hearing Coordinator, 11811 S Sunset Dr., Suite 2100, Olathe, KS 66061; or the appeal portal.

State guidance: Single-family residential appeals must go through BOTA's Small Claims division before the full state Board of Tax Appeals.
