Workers’ Compensation Insurance in Michigan

Michigan requires coverage for private employers regularly employing one or more workers at least 35 hours per week for 13 weeks in the preceding 52, or three or more employees at once. Agricultural employers, householders, and public employers have distinct tests; exclusion forms are limited to businesses where all employees can be excluded and no subcontractors are used. 1,2

What Is Workers’ Compensation?

Workers’ compensation can pay medical care and part of an employee’s lost wages after a work-related injury or illness. If you have staff, check who is covered in each state; owners, contractors and some workers may be treated differently. Read the national Workers’ compensation guide.

What to Watch for in Michigan

  • The Two Private-Employer Tests Are Independent

    Either three simultaneous employees or the one-worker hours-and-weeks test triggers coverage. Count part-time workers for the three-person test and track a single worker’s prior 52 weeks separately. 1

  • Agriculture and Domestic Work Have Separate Tests

    Agricultural employers need coverage at three employees working 35 hours weekly for 13 consecutive weeks; householders have a similar 35-hour/13-week test for domestic servants. Don’t apply the general private-employer count without checking the job category. 1

  • WC-337 Is Available Only for an All-Eligible Workforce

    The Agency says an employer may file the exclusion form only if all employees can be excluded under the Act and it uses no subcontractors; otherwise it must obtain a policy. Ask the broker whether owner, family, and subcontractor roles make your whole business ineligible before relying on a form. 2

  • Partners, Officers, and Manager-Members Count Differently Than Sole Proprietors

    Michigan treats a partner, corporate officer, and LLC manager-member as an employee of the entity, while a sole proprietor is not an employee of the sole proprietorship. Confirm how entity structure and owner duties affect the policy roster. 1

Who Regulates Insurance in Michigan

Michigan Department of Insurance and Financial Services

The Michigan Department of Insurance and Financial Services licenses agents, agencies and companies, supervises insurance business, and helps resolve complaints. You can use its state lookup or complaint service to check a license or raise an insurance issue. 3,4,5

Surplus-lines tax and stamping office

Reported tax rate: 2.5% combined surplus-lines tax and regulatory fee on premium when Michigan is the insured's home state Michigan's Property and Casualty Guaranty Association is funded by insurers authorized to transact in the state; an insurer procured solely under Chapter 19 is expressly not considered authorized for that chapter. The surplus-lines policy must carry a notice that the insurer is not Michigan-licensed and insolvency claim payment may not be guaranteed. 6,7,8

Providers With Documented State Licenses

These providers publish a national listing for Workers’ compensation; the state records document licenses for the entities and roles shown below. Some records rely on company-reported information rather than independent regulator verification. A national listing does not confirm the product is available in Michigan. Check the regulator’s license lookup and confirm state availability for your business when requesting a quote.

  • CorgiCorgi Insurance Services, Inc.Insurance producer · checked 2026-09-28Corgi’s company producer-license table lists 50 jurisdictions: 49 states and the District of Columbia, including DC license 3003091619. New Mexico does not appear in the table and is not included here; the omission does not establish that Corgi is unlicensed there. The company-reported table has no stated as-of date and does not establish product availability. 11
  • ERGO NEXT InsuranceNext First Insurance Agency, Inc.Insurance producer · checked 2026-09-28ERGO NEXT’s current license table lists Next First Insurance Agency, Inc. in 50 jurisdictions, including Washington, DC; New York is excluded because its table rows name Next Insurance Services and AP Intego, not Next First. The table is company-reported; it does not establish product availability or provide state-regulator verification for each entry. 13
  • HiscoxHiscox Insurance Company Inc.Insurer · checked 2026-09-28Hiscox’s U.S. company information states that Hiscox Insurance Company Inc. is licensed in all 50 states and the District of Columbia. This is company-reported insurer authority for this entity and does not establish which company issues every Hiscox-branded product. 12
  • TechInsuranceSpecialty Program Group LLCInsurance producer · checked 2026-09-28TechInsurance’s current licensing page names Specialty Program Group LLC / SPG Insurance Solutions and lists state license numbers, but labels Rhode Island “Individual licenses” rather than identifying a license for the named agency. RI is omitted because this disclosure does not establish agency authority there; this is a search limitation, not an assertion that the company is unlicensed. The remaining state entries are company-reported and are not an insurance product availability map. 14
  • VouchVouch Specialty Insurance Services, LLCInsurance producer, Surplus-lines broker · checked 2026-09-28Vouch’s licenses page, effective January 16, 2025, lists producer licenses in all 50 states and DC. Its separate surplus-lines table includes Idaho number 870820, while a footnote says Georgia and Idaho do not issue agency-level surplus-lines licenses. Because those statements conflict for Idaho, this record keeps Idaho producer-only and does not treat the table number as established agency surplus-lines authority. The page is company-reported and does not establish product availability. 15

No. The Agency’s guide says all employees must qualify for exclusion and the business must use no subcontractors. 2
