Valuation limits
For 2026, Michigan's capped-value inflation multiplier is 1.027: 2026 capped value = (2025 taxable value − losses) × 1.027 + additions. Proposal A caps taxable-value growth until an uncapping transfer; taxable value cannot exceed SEV, and transfers, new construction, additions, or omitted property can change the cap.
