About the Casper Property Market
Casper is a city located in Natrona County, Wyoming. Every property inside the Casper city limits is assessed by Natrona County Assessor, which applies Wyoming property tax rules uniformly across the county.
Because Casper property values are set at the county level, the $230,000 county median home value and 0.68% effective tax rate apply to homes throughout the city. Homeowners who believe their Casper home is over-assessed have the right to file a appeal directly with Natrona County Assessor before the May 30 or within 30 days deadline.
Wyoming allows the assessor to defend or adjust the assessed value during a appeal, so Casper homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Casper Property Market Context
The property tax picture in Casper is shaped as much by Wyoming statewide policy as by anything unique to a city.
Wyoming market character
Wyoming has no state income tax, and residential property is assessed at 9.5% of fair market value. Effective rates are low at around 0.6%, but recent growth in Teton, Laramie, and Natrona counties has produced assessment pressure on high-value homes.
How Wyoming handles appeals
Wyoming homeowners protest to the County Board of Equalization, then the State Board of Equalization, then District Court. The process is clear and the state is procedurally fair.
When to file in Casper
Protests must be filed within 30 days of the assessment notice, which typically mails in April.
Common Casper Property Types
Casper 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
Retail, office, and small commercial along major corridors.
ProtestMax supports all of the above property types in Casper. Each appealpacket is tailored to the property's classification and uses comparable sales from Casper and surrounding Natrona County neighborhoods.
