Payroll Tax Deadlines for Employers in Michigan

Employers operating in Michigan must carefully track payroll tax deadlines to maintain compliance and avoid penalties. Meeting these deadlines ensures timely tax deposits and accurate reporting to federal and state agencies.

Key Payroll Tax Deadlines

• Federal Payroll Tax Deposits: Employers must follow the IRS deposit schedule based on their tax liability. Deposits can be semi-weekly or monthly. As of 2026, use the IRS Electronic Federal Tax Payment System (EFTPS) for timely payments.
• Federal Form 941 (Quarterly Federal Tax Return): Due by the last day of the month following the end of each quarter:
  • April 30 for Q1 (Jan-Mar)
  • July 31 for Q2 (Apr-Jun)
  • October 31 for Q3 (Jul-Sep)
  • January 31 for Q4 (Oct-Dec)
• Michigan State Withholding Tax Deposits: Michigan withholding tax payments are generally due either monthly or quarterly depending on the employer’s withholding amount. As of 2026, deposits must be made electronically through Michigan Treasury Online (MTO).
• Michigan Form MI-W4 (Withholding Exemption Certificate): Employees complete this form to determine withholding allowances. Employers should update payroll systems promptly to reflect changes.
• Michigan Annual Withholding Tax Return (Form MI-W3): Due January 31 following the end of the calendar year. This form summarizes all state income tax withheld from employees.
