Michigan Assessor Manuals

State of Michigan Assessor's Manuals:

MCL 211.10e requires all assessing officers to use only the official assessor's manual or any manual approved by the State Tax Commission.  At their meeting on May 27, 2025, the State Tax Commission approved to distribute the 2025 manual to all assessors in 2025 with authorization for use in creation of the 2026 assessment roll.

The 2025 manuals provided below include changes to the base costs.  These changes are automatically incorporated into the costs contained in CAMA systems through MMSVP.

At their meeting on June 6, 2017, the STC rescinded the current version of Volume III and authorized the release of the 2017 Volume III.
