What Is Workers Compensation Insurance?

Workers compensation insurance is a no-fault system that pays for an employee’s medical bills, lost wages, and rehabilitation when they suffer a work-related injury or occupational disease. In exchange, employers are protected from most employee lawsuits related to the incident.

How Much Does Workers Compensation Insurance Cost in Michigan?

Premiums are driven by three components:

Cost Factor	How It Works	Typical Range
Class Code Rate	Each occupation is assigned a risk-based rate per $100 of payroll by the National Council on Compensation Insurance (NCCI).	$0.25 – $15.00+
Payroll	Higher payroll equals higher premium because rates apply to every $100 in wages.	N/A
Experience Modifier (MOD)	Measures your claims history against industry peers (1.0 is average).	0.70 – 1.50+

Assigned Risk Pool: The Last Resort

Businesses with high MODs or new ventures in hazardous trades may be declined by private insurers. In that case, coverage is obtainable through the Michigan Workers' Compensation Placement Facility (MWCPF). Premiums are typically 15–25% higher, so developing a strong safety culture is key to moving back into the voluntary market.

Frequently Asked Questions

Is workers comp required for remote employees?

Yes. If they are Michigan residents on your payroll, coverage is mandatory even when working from home.

Can I self-insure?

Large employers with a net worth of $10 million+, positive cash flow, and a solid safety record can apply for self-insurance authority through the Workers’ Compensation Agency (WCA). A surety bond is usually required.

Does workers comp cover COVID-19?

Claims are evaluated case-by-case. Healthcare workers and first responders have an easier path to compensability, while other industries must prove workplace exposure.

How long do I have to file a claim?

Employees should notify you within 90 days of injury and must file a claim within two years. Prompt reporting helps avoid penalties and litigation.
