The Assessor reported the office completed township work for 2026 and processed 599 certificates of error for 2025 tax bills, a routine post-bill increase officials said they expect when residents receive bills and discover missing exemptions.
"We've processed 599 certificates of error for 20 25 tax bills," the Assessor said, noting many claimants seek senior or disability exemptions. The office reminded residents that certain exemptions and renewals are administered through township mailings and that the county posts explanatory information on its website.
On legislation, the Assessor said a change to farmland assessment was signed into law (referred to in the meeting as "Public Act 104-0468") and that the Department of Revenue will issue a fuller summary later this summer or early fall. "This change will impact the tax bills for the 1st time in '28 payable in '29," the Assessor said, adding staff expects to have more detailed guidance after fall conferences.
The committee also discussed senior-exemption thresholds and the senior-freeze income limit (the meeting noted a $75,000 threshold for 2026 and indexing in future years). Committee members said the county should consider a short, clear insert with exemptions information for tax-bill mailings to reach senior residents who may not get online notices.
