Michigan Estimated Quarterly Tax

Michigan requires estimated quarterly tax payments if you expect to owe more than $500 in state tax. The safe harbor is paying 90% of your current year tax liability or 100% of your prior year tax. Payments are due on the same dates as federal (April 15, June 15, September 15, January 15).

Why It Matters

Self-employed workers and freelancers in Michigan must make estimated quarterly payments for both federal and state taxes. Missing payments or underpaying can result in penalties from both the IRS and Michigan Department of Treasury. Michigan charges a 25.0% penalty rate on underpayments. Planning ahead helps you avoid surprises at tax time and manage cash flow throughout the year.
