From Detroit’s assembly lines to small retail shops in Traverse City, accidents happen—and when they do, Michigan workers compensation laws ensure that your business and your employees are protected. Whether it’s a slip, strain, or serious illness, compliance with these laws is not optional.
This guide outlines who needs coverage, what benefits are included, how much it costs, and what the claims process looks like under Michigan workers comp laws 2025. Understanding your responsibilities under Act 317 is essential to avoid fines, lawsuits, and business interruptions.
Who Needs Workers' Comp in Michigan?
Under Michigan law, workers’ compensation becomes mandatory when:
- You employ one or more workers for 35 hours or more per week for 13 weeks or longer during the preceding 52 weeks
- You are a private employer that regularly employs three or more workers at any time, including part-time or seasonal staff
- You operate an agricultural business with three or more employees working 35+ hours/week for 13 or more consecutive weeks
This rule applies to nearly all industries—from automotive factories to home-based businesses.
Who's Exempt?
- Sole proprietors without employees
- Corporate officers or LLC members with 10%+ ownership (must file Form WC-337)
- Independent contractors who pass the IRS 20-Factor Test
Misclassifying workers as contractors can result in steep fines and lawsuits. Household employers may also need coverage, depending on hours worked.
What Michigan Workers' Comp Insurance Covers
A valid MI workers comp insurance policy includes multiple benefits to ensure injured employees receive care while protecting the employer from legal claims. These include:
Medical Expenses: Covers treatment, hospitalization, surgery, rehab, and prescriptions
Wage Loss Benefits: Pays approximately 80% of an employee’s after-tax wages (about 60% of gross wages) while they’re unable to work
Death Benefits: Provides compensation to surviving dependents, including funeral costs
Occupational Disease Coverage: Covers illnesses like repetitive stress injuries or chemical exposure
Mental Health Benefits: Includes conditions like PTSD when directly tied to work duties. Recent legislation provides presumed coverage for certain mental health conditions among first responders.
Importantly, Michigan’s “exclusive remedy” law protects employers from civil lawsuits—so long as they maintain valid coverage.
*Benefits have a 7-day waiting period. If you’re off work less than 7 days, only medical expenses are covered. If you’re off work more than 14 consecutive days, you’ll be paid retroactively from day one.*
