Understanding Idaho's Property Taxes

The purpose of the Assessor's office is to locate, identify, and value all taxable property in Teton County Idaho. The result is assessed property values subject to taxation.

The ad valorem (property) tax is the primary source of revenue for county and city governments and other taxing entities that serve and protect our communities such as library, ambulance, fire, cemetery, and school districts. It is the assessor's duty to assess the properties (every 5 years) within the county uniformly and to the specifications of Idaho law so that all properties are taxed fairly and equitably. The assessor does not set taxes. The taxes are determined by the budgets that each taxing district turns in annually.

The assessor's office analyzes sales price, construction costs, rent and other pertinent data to estimate the correct valuation of the property. All appraisal evaluations are monitored by the State Tax Commission to ensure compliance with state law and all evaluators within the state must follow a continuing education program every two years to remain certified. Teton County Idaho contracts with Marshall Appraisal Inc. to conduct all necessary appraisals. It is required that the County keep track of property ownership changes, maps of parcel boundaries, and to plat parcels as they are split from larger parcels. The office must also keep descriptions of building and property characteristics files current as well as keep track of individuals and property eligible for exemptions and other forms of property tax relief.

The Assessor's office works very closely with the County GIS department to maintain the integrity of our database and the proper identification and addressing of all parcels.
