What is the Michigan franchise tax?

Michigan doesn’t have a franchise tax, but nearly every business encounters one of its major business taxes, each with its own rate, calculation method, and filing schedule. The main one is the Corporate Income Tax, a flat 6% hit on your corporation's apportioned federal taxable income. Michigan uses a 100% sales factor for apportionment, meaning only your Michigan sales determine your tax exposure. 

Financial institutions face a different beast entirely. Michigan imposes a true franchise tax on banks and similar entities based on net capital, an equity-based measure tied to capital rather than income. This often catches growth-stage financial institutions before they're even profitable.

Additional state taxes

The Corporate Income Tax or elective Flow-Through Entity tax rarely stands alone in Michigan. When operating in the state, you'll also handle:

• Sales and use tax
• Payroll withholding
• Unemployment insurance
• Property tax
• City income taxes

All of these taxes interconnect with your individual or corporate returns, making comprehensive compliance planning essential for avoiding penalties across multiple jurisdictions and tax types.

Penalties and compliance

Fail to file a Michigan business tax return, and the meter starts running immediately. The Department of Treasury imposes penalties and interest that compound quickly, making timely compliance essential for avoiding expensive consequences.

• Late filing penalties
• Late payment penalties
• Daily interest charges
• Lost good standing
• Administrative dissolution
• Court access restrictions
• Underpayment penalties

Track due dates, calculate estimates accurately, and schedule payments before deadlines to avoid an expensive learning curve. Michigan's penalty and interest charges compound quickly and can significantly exceed your original tax bill if left unpaid.
