About the Coggon Property Market
Coggon is a city located in Linn County, Iowa. Every property inside the Coggon city limits is assessed by Linn County Assessor, which applies Iowa property tax rules uniformly across the county.
Because Coggon property values are set at the county level, the $200,000 county median home value and 1.55% effective tax rate apply to homes throughout the city. Homeowners who believe their Coggon home is over-assessed have the right to file a protest directly with Linn County Assessor before the April 30 deadline.
Under Iowa law, a protest cannot increase your assessed value — it can only stay the same or go down. That makes a Coggon protest a low-risk way to push back against an over-assessment, especially for homeowners with strong comparable sales evidence.
Coggon Property Market Context
Every Coggon homeowner operates under Iowa property tax law, and understanding the state context is the first step toward a successful challenge.
Iowa market character
Iowa reassesses on a two-year cycle (odd years), and recent cycles have produced 20-30% jumps in many counties. The state uses a rollback factor to soften tax-bill impact, but the underlying assessed value still drives exemptions and future sales.
How Iowa handles protests
Iowa homeowners file a protest with the local Board of Review, then the Property Assessment Appeal Board or District Court. Protest does not risk an increase in assessed value. Informal review with the assessor is encouraged.
When to file in Coggon
Protest window runs April 2 through April 30, annually. This is one of the most compressed windows in the country — file as soon as notices arrive.
