About the Gardner Property Market

Homeowners who believe their Gardner home is over-assessed have the right to file a appeal directly with Johnson County Appraiser before the March 15 or 30 days from notice deadline.

Gardner Property Market Context
The property tax picture in Gardner is shaped as much by Kansas statewide policy as by anything unique to a city.
Kansas market character
Kansas has effective tax rates around 1.4%, above the national average. The state reassesses annually, and appraised value is set at 11.5% of market value for residential. Rapid growth in Johnson and Sedgwick counties has pushed assessments up aggressively.
How Kansas handles appeals
Kansas homeowners appeal to the county appraiser (informal), then the Small Claims division of the Court of Tax Appeals. The state explicitly allows "payment under protest" as an alternate path.
When to file in Gardner
Informal appeals must be filed within 30 days of notice (usually March). Payment-under-protest appeals follow the December tax deadline.
Common Gardner Property Types
Gardner homeowners typically file protests across these property categories:
Single-family homes
The most common residential type and the dominant protest category.
Condominiums
Common in denser parts of the city and near employment centers.
Townhouses
Attached-home neighborhoods in newer subdivisions.
Small multi-family
Duplexes and 2-4 unit buildings assessed as income property.
Commercial
