Michigan charges a flat 4.25% on federal AGI less a $5,900 exemption per filer, and under H.B. 4961 it follows BOTH federal deductions for 2026-2028 — one of the few states that does. If you work in Detroit, the city adds its own tax on top: 2.4% for residents, 1.2% for non-residents, with a $600 exemption. That city tax is not included here.
What it means on a real paycheck
Take a single filer earning $50,000 a year, $8,000 of it in tips. Against the same person with no tips to declare, the federal deduction is worth $960.
In Michigan it is worth $340 more, because the state follows the federal deduction. Together that is $1,300.
How Michigan works out the tax
Michigan charges a flat 4.25%, after an exemption of $5,900 a person. It begins from your federal adjusted gross income and applies its own reliefs from there.
