Workers' Comp Insurance in Michigan: Requirements & Costs

Michigan law requires almost every employer to carry workers' compensation insurance. Here's a complete guide to Michigan workers' comp — what's required, what it covers, what it costs, and how to keep premiums down.

Who Needs Workers' Compensation in Michigan?

Michigan requires workers' comp for:

All employers with one or more employees working 35+ hours/week for 13+ weeks
All employers with three or more employees at any one time (full or part-time)
All household employers paying $1,000+ in a quarter
Construction and certain other industries — even single employees

Penalties for Not Having Coverage

$1,000 fine per day uninsured
Possible misdemeanor or felony charges
Personal liability for all employee injury costs
Stop-work orders
Loss of right to deny employee injury claims

What Workers' Comp Covers

Medical Benefits

100% of reasonable and necessary medical treatment for work-related injuries — emergency care, doctor visits, surgery, rehab, prescriptions. No deductible for the employee.

Wage Loss Benefits

80% of after-tax wages while unable to work. Michigan has weekly maximum/minimum amounts updated annually.

Specific Loss

Scheduled benefits for amputations, severe injuries to specific body parts.

Vocational Rehabilitation

Retraining if the injured worker can't return to their previous job.

Death Benefits

For work-related fatalities, benefits to surviving family members.

What Workers' Comp Does NOT Cover

Injuries from intoxication or drug use
Self-inflicted injuries
Injuries during personal activities while on the clock
Some independent contractors (depending on classification)
Mental-only stress claims without physical injury (with some exceptions)

How Much Does Workers' Comp Cost in Michigan?

Cost is calculated as: (Payroll ÷ 100) × Class Code Rate × Experience Modifier

Sample Michigan Rates per $100 of Payroll

Clerical office: $0.15-$0.30
Restaurant: $1.50-$3.00
Retail: $0.80-$2.00
General contractor: $5.00-$15.00+
Roofing: $20.00-$45.00
Trucking: $4.00-$10.00
Auto repair: $4.00-$8.00

Real Examples

Office firm with $400K payroll: ~$800-$1,200/year
Restaurant with $500K payroll: ~$8,000-$15,000/year
Roofing contractor with $300K payroll: ~$60,000-$135,000/year

Experience Modifier

After 3+ years in business, your premiums are adjusted by your "Experience Mod" (E-Mod) — based on your actual claim history vs. industry average:

1.0 = average
Below 1.0 = better than average (discount)
Above 1.0 = worse than average (surcharge)

A 0.85 E-Mod means 15% discount. A 1.25 E-Mod means 25% surcharge. Active claim management matters a lot.

How to Lower Your Workers' Comp Premium

Safety programs — documented training, equipment, procedures
Return-to-work programs — get injured employees back faster
Active claim management — quick reporting, follow-up, fraud investigation
Drug-free workplace certification
Higher deductibles (if available)
Accurate classification — avoid misclassification that inflates rates
Bundle with other commercial coverage

Michigan Worker Classifications Matter

One of the most common premium issues we see: workers improperly classified into higher-cost class codes. A clerical employee shouldn't be coded as construction. Annual classification audits save real money.
