Property Tax Appeals in Johnson County, Kansas
Johnson County owners receive a Notice of Appraised Value each spring and may request an informal appeal within 30 days of mailing. The ordinary 2026 spring window has passed; confirm any property-specific notice separately. Payment under protest is filed with the County Treasury and Financial Management Office with tax payment under the county's November 1 through December 20 rule, or by the following January 31 when an escrow agent paid at least half. Weekend or legal-holiday deadlines extend to the next business day. If taxes are paid after those deadlines, the county says to file the protest when paying. Eligibility depends on whether the owner already had a meeting with the County Appraiser on that year's valuation. FairPath's owner-guided packet remains available year-round to organize county records, sales, condition documents, owner questions, and official links. It does not establish eligibility, automate Johnson County valuation, file with the county, or represent the owner.
Assessment context: Johnson County values taxable real property at fair market value as of January 1. Confirm the property record, quick reference number, parcel identifiers, classification, land and improvement values, year built, living area, and characteristics before deciding what requires explanation. Johnson County's public land-record and appraiser resources support parcel-level review, while some AIMS data products are separately licensed. ACS 2024 five-year data reports a $391,200 median owner-occupied value, $4,447 median annual real-estate taxes, and about 69 percent of housing built before 2000. These figures describe county demand and housing age; they do not prove that a subject is overvalued, unequal, or likely to receive a reduction.
Filing process: For payment under protest, complete the county's PUP form and file a copy with the County Treasury and Financial Management Office with tax payment under its November 1 through December 20 rule. When an escrow agent pays at least one-half of the taxes, the county gives the following January 31 as the deadline. Its calendar extends weekend or legal-holiday deadlines to the next business day. If taxes are paid after those deadlines, file the protest at the time of payment. The county then schedules a hearing in person at the Sunset Drive office building, by telephone, or as a residential hearing based on submitted evidence. Preserve the filed form, payment record, and hearing confirmation. The ordinary spring informal period has passed; the actual Notice of Appraised Value governs its 30-day filing window. If dissatisfied with a county decision, an owner generally has 30 days to pursue the next Kansas level. Kansas permits only one county-level protest route per tax year, so a prior informal appeal affects payment-under-protest eligibility.
Evidence to review: Johnson's notice identifies possible issues such as market value, unequal treatment compared with like property, classification, or agricultural use. A market-value file can include verified arm's-length sales near January 1 with address, date, price, living area, age, lot, quality, renovation, and location differences. An equalization file should use genuinely like properties and consistent county fields. Dated photographs, inspections, repair estimates, permits, and contractor scopes can explain condition that existed by the valuation date. Correct county-record errors with an owner document tied to the disputed field. The 2026 notice asks for an owner's estimate and basis, so the exhibit index should connect facts to that estimate. FairPath organizes materials but does not determine the estimate or outcome.
Current deadline guidance: Payment under protest: November 1 – December 20 with payment, or the following January 31 if an escrow agent paid at least half; weekend/holiday and later-payment rules apply. Kansas allows 30 days after the Notice of Appraised Value mailing for an informal appeal. Johnson County's ordinary 2026 spring informal window has passed; the current county residential mockup shows a February 23 mailing and March 25 deadline, but the actual property notice controls. For payment under protest, the county says to complete the PUP form and file a copy with the County Treasury and Financial Management Office between November 1 and December 20 with payment, or by the following January 31 when an escrow agent paid at least one-half of the taxes. Its calendar automatically extends a deadline falling on a weekend or legal holiday to the next business day. If taxes are paid after these deadlines, the county says the protest must be filed at the time the taxes are paid. Only owners who have not had a meeting with the County Appraiser on the valuation for the same tax year may file.
Johnson County's PUP rule is November 1 through December 20 with payment, or the following January 31 when an escrow agent paid at least half; weekend or legal-holiday deadlines extend to the next business day.
The county says that when taxes are paid after those deadlines, the protest must be filed at the time the taxes are paid.
The county allows payment under protest only for owners who have not had a meeting with the County Appraiser on the same year's valuation, so track whether a spring informal appeal was filed.
The county's current 2026 residential mockup shows a February 23 mailing and March 25 deadline; it is an example, and the actual property's notice controls. A prior-year matter does not preserve current-year rights.
