Registration is not a flat fee
For most passenger vehicles from 1984 onward, Michigan calculates plate tax from original MSRP and a statutory fee schedule. Used and out-of-state vehicles use age-based fee levels. EV and plug-in-hybrid surcharges are separate from that amount.
Michigan applies a 6% state sales/use tax and does not permit local governments to add vehicle sales tax. Ordinary private-party purchases use a different value basis from dealer sales, while dealer trade-in deductions are capped for 2026.
