Sanilac County adopts 2025 equalization report valuing county at $4.075 billion

The Sanilac County Board of Commissioners on April 15 adopted the county's 2025 equalization report, setting the county equalized value at $4,075,408,342 and authorizing the equalization director to make any amendments before submission to the Michigan State Tax Commission.

Keegan Bangle, the county's equalization director, walked the board through the process used to produce the report, including sales and appraisal studies the office completed this year. He told commissioners the office completed 117 studies across townships and cities and highlighted the difference between assessed value and taxable value. "A sales ratio is created, when the assessed value of a property is divided by the sale price," Bangle explained, adding that a "perfect sales ratio is 50%" and that the state requires ending ratios to be between 49% and 50%.

The presentation showed countywide assessed value rising about 10.95% from 2024 to 2025 and taxable value increasing by 5.94%. Bangle also described a small factor (0.9522) that had to be applied to bring one township's commercial class into the required ratio after a late personal-property statement altered the assessed totals.

Finance Chairman Sarkelos moved to adopt the report and the board approved the motion by voice vote. The board authorized the equalization director to make any needed technical amendments before the formal submission to the state tax commission.
