The Michigan State Tax Commission issued a bulletin outlining 2026 procedures for millage requests and rollbacks. The bulletin details calculation methods and key treatments, sets the 2026 inflation rate multiplier at 1.027, requires filing Form L 4029 with the county by Sept. 30, notes that Headlee rollback does not apply in 2026 to new millages authorized after April 30, and instructs counties to reduce their 2026 base tax rate for estimated convention facilities and cigarette tax revenues.
