Assessor: county valuations within state ratio thresholds; assessment notices to include tax comparisons

Jessica Roach, Jefferson County assessor, presented the office's market analysis and the county's ratio study during the May 28 meeting, saying the county remains within the Idaho State Tax Commission's acceptable range and will present valuations to the state board of equalization this summer.

Roach said the county's 2023 average sale price was about $440,700 (compared with an average of $482,500 in 2022) and that 2024 sales show an upward swing toward roughly $464,000. She cautioned the board that changes in what types of properties are selling (more starter homes and fewer higher‑end sales) influence median values and therefore assessed valuations.

Roach referenced Idaho Code 63‑3‑14, which requires valuation at market value, and explained the ratio study mechanics used by the state tax commission (target range 90–110%). She said the county's internal follow‑up study after establishing the 2024 values showed a low of about 94 and a high of about 96, keeping the county inside the acceptable band and avoiding an automatic state follow‑up.

The assessor also noted an ongoing lawsuit by public utilities over valuation thresholds that has prompted the state tax commission to monitor utility and commercial classes closely. Roach urged commissioners and department staff to direct constituents with tax questions to the treasurer's office or taxing districts because the assessor's office handles valuation, not levy or tax settings.

Roach concluded by reminding officials that assessment notices will include the required historical tax and valuation comparisons and that taxpayers with questions should contact the assessor's office before pursuing appeals.
