Michigan Business Insurance Requirements

Is business insurance required in Michigan?

In Michigan, state law mainly requires two kinds of business insurance:

• Workers' compensation, once you meet the state's employee rule: required with 3+ employees, or 1+ working 35+ hours a week.
• Commercial auto, for vehicles your business owns, because every vehicle on the road needs liability coverage.

Most other coverage is required by the people you do business with rather than by law:

• Commercial landlords typically require general liability and may require property coverage.
• Clients and general contractors often require general liability, additional insured status and proof of workers' comp.
• Licensed professions and trades may need insurance or a bond to get or renew a license; check with the board for your field.

General liability is generally not mandatory under Michigan law, but most businesses that serve customers, visit job sites or rent space end up needing it.

Workers' compensation in Michigan

Michigan requires workers' compensation for employers with 3 or more employees, or with at least 1 employee who works 35 or more hours a week. That second rule catches many small businesses with just one full-time worker.

Coverage is bought from private insurers. Michigan is not a monopolistic state. Some larger employers qualify to self-insure, but that isn't practical for most small businesses.

If you're below the threshold, workers' comp is still worth considering: it protects you from lawsuits over workplace injuries and is often required by general contractors and clients.

What else Michigan business owners should know

• Count hours, not just headcount. Because one full-time employee can trigger the requirement, review schedules before you hire your first full-time worker.
• Auto-heavy businesses. Michigan's auto insurance system has its own rules. Business-owned vehicles should be on a commercial auto policy written for Michigan; ask a Michigan-licensed agent how the state's auto rules apply to your fleet.
• Licensed trades. Builders, electricians and other trades licensed in Michigan should check their licensing requirements for insurance or bonds.

Common coverage gaps for Michigan businesses

• Assuming a personal policy covers business use. Home and personal auto policies often exclude business activity, equipment and vehicles used for work.
• Hiring before arranging workers' comp. Coverage needs to be in place when the employee who triggers the requirement starts, not after an injury.
• Missing contract wording. If a client asks to be an additional insured or wants a waiver of subrogation, your policy needs the matching endorsement before you start work.

How much does business insurance cost in Michigan?

We don't publish a Michigan-specific median, because reliable state-level price data isn't publicly available. What we can share are national medians. According to Insureon's 2026 data from 100,000 small-business customers (most with 1–4 employees):

Prices in Michigan can be higher or lower than these figures. Your quote depends on your industry, payroll, revenue, number of employees, claims history, the limits and deductible you choose, and where in the state you operate. Riskier work costs more: Insureon's construction customers pay a median of $82 a month for general liability and $254 a month for workers' comp, compared with $29 and $40 for consultants.

How to verify requirements and coverage in Michigan

1. Check workers' comp rules with the state. The Michigan Workers' Disability Compensation Agency is the authority on who must carry coverage, exemptions and penalties.
2. Check your license. If your trade or profession is licensed in Michigan, the licensing board can tell you whether proof of liability insurance, a bond or workers' comp is part of getting or renewing your license.
3. Read your contracts and lease. Clients, general contractors, venues and landlords set their own minimums, often $1 million per occurrence and $2 million aggregate for general liability, and may ask to be named as an additional insured.
4. Confirm the insurer is licensed. The Michigan Department of Insurance and Financial Services regulates insurance companies and agents in Michigan. Use it to check that an insurer or agent is licensed and to file a complaint.
5. Keep proof handy. Ask for a certificate of insurance (COI) as soon as your policy starts so you can send it to clients quickly.
